  PHOTOGRAPHIC MACHINE FOR COMPOSITION OF PRINTING TYPE.



   The present invention relates to improvements to photographic composing machines. Photographic compositing machines produce character lines, from lines composed of individual character-bearing elements, directly on sensitized film or paper; a suitable vacuum plate suitable in particular for offset printing and gravure printing processes can be prepared from this film or paper. In these machines, the lines of characters are produced, letter by letter, from lines of elements, bearing characters which are capable of being photographed and possess basic form and dances.

   The elements may have the general shape of the dies used in commercial line composition and block line molding machines, but have a photographic character on their flat, wide side. These character-bearing elements are individually and successively removed from a compound line to be transferred to a camera with a view to photographing their respective characters on the sensitized film or paper.

   The correct letter and word spacings for successive photographic exposures are obtained by moving a film holder step by step for each exposure, the amplitude of the movements step by step being controlled by the thickness of the edge of the elements successively removed; this thickness is equal or proportionate to the length of composition of the particular character disposed on the wide lateral face of the element considered. A machine conforming to this type and operating in an almost fully automatic manner has been described in Belgian patent 489,256.



   These machines are normally mounted on a heavy metal frame and their total weight of around 1400 kg virtually eliminates the possibility of moving them easily from one place to another. These machines: however operate satisfactorily, but there is a need for a simplified photographic composition machine, relatively light in weight, operating on the same principles and capable of being

  <Desc / Clms Page number 2>

 attached to high-performance machines of the type mentioned or to replace them if necessary.



   The main aim of the present invention is therefore to provide a photocomposition machine of this type, which is relatively light and transportable, for example a machine which can be mounted on an ordinary console and in which most of the heavy supports have been eliminated. and heavy duty machine mechanisms.

   The sequence of operations performed in the photocomposition of characters, using 1-'aide.la machine described in the patent cited above by reference as well as the machines forming the subject of the present invention, essentially comprises:
1 - The composition, in a sliding assembly trolley, of the dies bearing the individual characters to be photographed,
2 - Transfer of the assembled line to an assembly elevator,
3 - The rise of the elevator to trigger an electrical contact to allow a delivery trolley actuated by a spring to propel the line to a justification station,
4 - the optional justification of the assembled line or a selected part of it at the justification station, '
5.

   - the release of a mobile power supply rack with the assembled line and a simultaneous start-up of the camera mechanism comprising the means responsible for transporting the dies, one by one, from the front end of the assembled line to the photographic station, and from there to a matrix recovery system,
6 - the return of the feed rack and the delivery carriage to their initial positions when the photography of a line of dies has been carried out, and the return of the film holder located in the camera to its initial position starting so as to put it in position to photograph the next line of characters.



   In the photocomposition machines described in the patent mentioned above, and used with the flexible justification mechanism described in Belgian patent no.505,016. all these operations, with the exception of operation no. 3, are carried out mechanically by suitable mechanisms actuated by a main camshaft driven by an electric motor.

   The dies are placed in a store in the form of a channel, from where they are withdrawn to compose them in an assembly elevator, by manipulating a keyboard; when the elevator has been lifted by hand to release the delivery carriage and thereby advance the compound line to the justification station, levers actuated by appropriate cams operate in a timing plan to control the justification mechanism ; when this is completed, the feed rack is released so that it can move forward; the camera and the die recovery systems then begin to operate.



   When the photography of a compound line is completed, the feed rack and delivery carriage are automatically returned to their starting positions, in which they are locked until they are released again by the following sequence. operation.



   In the light photocomposing machines according to the present invention, all the operations of the above-mentioned sequence are carried out by hand; the main camshaft is eliminated; the magazine and the keyboard are also eliminated and a new kind of manual composition device is used in their place.

   The release of the feed rack, in order to allow the advance of the assembled line of dies from the justification station to the photographic station, is effected by the manual operation of the matrix recovery system; the operation of this system is combined so as to actuate the mechanism

  <Desc / Clms Page number 3>

 of the camera and the means responsible for transporting the matrices from the
 EMI3.1

 EMI3.2
 camera canism,

   the return of the alàmentation rack and the delivery carriage to their initial positions, etc., set in motion various new mechanisms intended to carry out these operations; these mechanisms will be described in detail a little later. An electric motor drive is provided to actuate the means responsible for transporting
 EMI3.3
 the matrices to the photographic station and an electric power source supplies the light source of the camera.



   The typesetting machines of the present invention are
 EMI3.4
 particularly interesting for certain special works of pr3mery in which a direct composition made by hand is preferred to a composition by keyboard. For example, many of the Oriental and Middle Eastern languages have alphabets made up of a very large number of individual characters; one can cite, as striking examples of these
 EMI3.5
 gu.es, Chinese and Japanese. In these cases, keyboard dialing is impractical and you must use direct dialing.
 EMI3.6
 hand.

   Thus, the composition of mathematical signs and of other scientific signs frequently requires the use of a very large number of specialized characters, and the machine according to the present invention is particularly useful for this kind of work. Mention may be made, among other uses of the invention, of the advertising composition in which relatively small texts are used in cooperation with illustrations; we can here-

 There are also various special printing works: concerning, for example, greeting cards, catalogs, labels and articles in which lines of text or single words are to be printed on maps and the like.

 if, in li <npress3on of different business prints, such as ruled prints, it is desirable to photograph the characters of a given line made up of different elements a large number of times.

The manual composition device, which constitutes an element of the present invention and which allows the elimination of the keyboard and the associated magazines of the heavy-duty machine, comprises a support, an assembly carriage mounted on this support and slidable at hand in a channel of the assembly elevator, an adjustable guide mounted on this assembly carriage and capable of moving relative to the latter, and finally locking means for locking together this carriage and this guide, which can move in a single block to the elevator to transfer to it a line composed of elements.

   The locking means preferably comprise a shoe capable of sliding in a slot in the support, the end of this slot in the support adjacent to the elevator constituting a stop with which the shoe can come into contact to limit the movement of the lift. assembly trolley and adjustable guide towards the interior of the elevator. The adjustable guide and the front end wall of the carriage constitute two adjustable walls with respect to one another, their adjustment being able to be carried out, in accordance with the invention, as a function of the length of the line to be composed.



  To this end, a device for determining the length of the lines comprises a graduation and an index capable of moving thereon to indicate the length of the line to be composed; there is preferably provided a notch centering member aligned with one end of the graduation and capable of receiving one of the adjustable walls of the composition device to facilitate the relative adjustment of these walls as a function of the length chosen for the line.



   Like the heavy-duty machine, the machine according to the present invention comprises a movable feed rack with a line composed of elements, while these are supplied to the means for moving the elements, and a locking member which can engage in the supply rack to lock it or disengage it to unlock it.

   According to the invention, a locking control mechanism is mechanically connected to the locking member of the rack, this mechanism can move to unlock the rack, in response to the manual positioning of the waste recovery system. elements, in order to receive or re-circulate the matrices when they are unloaded from the camera; this positioning of the element recovery system acts simultaneously on a member whose movement triggers the camera mechanism and the means responsible for transporting the elements one by one to the photographic station.



     In its preferred form, the element recovery or recirculation system according to the invention comprises an accumulator bar, on which the elements unloaded from the camera can be recovered, and a delivery system. circulation to return the items in the proper order for re-photographing, with the accumulation bar and recirculation system being used in a selective manner according to the requirements of the print types to be composed.



   The accumulator bar and recirculation system can both be moved by hand to operate either as desired and to put either or both into the operating position. the other automatically activates the mechanism, the movement of which unlocks the power rack, as well as the mechanism which triggers the movement of the means of transporting the elements and that of the camera mechanism. Thus, the accumulation bar can be moved by hand so as to align it with the unloading station of the camera in order to receive each element as it leaves the camera; the items thus recovered can be stored in any suitable space for later use as desired.

   The recirculation system includes an endless belt extending from the discharge station to a point above the assembly elevator; a corridor intended to receive the elements from the endless belt has a discharge end capable of moving to a position close to the assembly elevator in order to successively deliver the elements to the latter so that they are assembled again in one line.

   A guide block is provided

  <Desc / Clms Page number 5>

 laid above the end of the conveyor, in alignment with the camera dump station, to guide the elements from the dump station to the conveyor o The guiding block can be removed out of this alignment when the accumulation bar is lowered to the operating position; consequently, when the accumulation bar is in the operating position, the recirculation system is inoperative and vice versa. The mobile mechanism responsible for triggering the operation of the film support and of the means for transporting the elements is engaged in preferably by part of the corridor as it approaches its delivery position.



   The present invention will be better understood by reference to the accompanying drawing which shows a photocomposing machine, light, transportable and having the preferred features of the present invention.

   The machine described in the present application is for most of its details substantially the same as the machine described in the patent cited above by reference. As explained in this patent, the characters to be photographed are mounted on dies such as those shown in Figure 3 of the present application. Dies bearing the appropriate characters are dialed into a line of the desired length and then individually photographed on a sensitized surface to produce a line of characters thereon.

   The dies have a thickness commensurate with the compositional width of the characters they carry, and the thickness of each die is used to adjust the motion of the film and achieve correct character spacing in the compound line.



   As seen in Figure 1, the machine according to the present invention is mounted on the upper part of a console designated as a whole by 8. If we consider the right portion of Figure 1, we see that a line of dies M-1 is composed by hand in a composition device 10 which can be removed from or introduced into the machine. The compound line is lifted by hand to a top position, where it triggers a lever 14 to release the line follower.



  Triggering lever 14 releases a line delivery lever 16 which is pushed to the left by a spring 1880 Lever 16 is connected to a delivery cart, the front or left end of which is connected to a line follower or pusher 20, which pushes the line consisting of the dies from the lifted elevator and along a feed channel 22 to a justification station 24. When the line follower 20 reaches the justification station 24 , it engages a line length determination member or jumper 26 carried by a supply rack 27, and locks onto this member.



   At the justification station 24, there is a justification mechanism designated as a whole by 28 and analogous to the mechanism described in the patent application cited above by reference; it differs, however, from the latter by certain characteristics which will be described in detail a little later.

   At the justification station 24, the mechanism 28 measures the difference between the actual length of the line composed of matrices and the length of the desired line, in order to determine what will be called in what follows "the". line insufficiency ", and modifies the movement of the film support so that its difference or line insufficiency is distributed over the line of characters produced on the film or over a selected part of this line, as explained in patent application already mentioned. At the same time as the justification measuring operation is carried out, the line composed of the dies at station 24 is pushed to the left against an end wall C which forms part of the camera housing.



   When the justification measurement is complete, the characters of the arrays are photographed individually by a camera mechanism designated as a whole by 30 and comprising a film holder 32 capable of moving vertically. To trigger the photograph, a

  <Desc / Clms Page number 8>

 accumulation bar plate 34, shown above. from the central part
 EMI8.1
 of Figure 1 and carrying a deaccunulation bar 36 is lowered by hand.



  When the plate 34 approaches its lower part, it actuates a clutch which triggers various parts of the mechanism :. of the camera. These parts include two endless conveyors (not shown) which transport the-
 EMI8.2
 the head element of the line of the dies, i.e. the die abutting against the wall G, from the justification station 24 to a photographing position, in which the character carried by the matrix is photographed and then to a discharge position 35 where the die is discharged onto the accumulation bar 36.

     lowering of the plate 34 of the accumulation bar also triggers the operation of various shutters which make
 EMI8.3
 part of the photographic mechanism and which release a supply rack 27 to allow it to move to the left. The feed rack 27 is connected by a member 28 to a line follower 20. The movement of the rack to the left therefore occurs in successive jolts, when each die reaches the wall C and leaves the component line. - sitiono
The rack 27 is connected by a set 38 of a shaft and gears to a vertical rack 40, on which the film holder 32 normally rests.

   Thus, this support 32 does not move down
 EMI8.4
 step by step when each item is photographed. The magnitude of each lowering movement of the film carrier depends on the compositional width of the character being photographed, and also on the line insufficiency mentioned above.
 EMI8.5
 However, if one wants to compose tables, and if one does not seem to want to apply a justification correction, each movement of the film support 32 is then only proportioned to the compositional width of the character to be photographed.



   When the photograph of a line of dies is completed, the line follower 20 is removed by hand to the right by means of a button 42 fixed to it. This withdrawal of the line follower 20 moves the release lever.
 EMI8.6
 : true sound 16 to the right, cgest = to = d1.re to its position shown in figure 1, and at the same time lift the film holder 32 to its position
 EMI8.7
 upper via a chain 44. The feed rack 27 is also withdrawn so as to lift the rack 40 to its upper position, in order to support the film holder 32 during the next photographing operation.

   We can then lift the plate 34 of the accumulation bar to disengage the clutch uniting the photographic mechanism to its drive and to lock the rack 27. The dies which have been accumulated on the bar 36 are then removed and they are disposed of as we want it. A composition rod provides a suitable means of removing the dies from the bar 36.



   Plate 34 is pivotable about a horizontal axis from an upper position shown in Figure 1 to a lower position.
 EMI8.8
 where the accunulation bar 36 is aligned with the die discharge station 35. Thus, after being photographed, each element passes to the discharge station 35 and the accumulation bar 36, hence
 EMI8.9
 a line of items can be taken out for redistribution in a store or in some other convenient way. The matrices accumulate on bar 36 in 1 / the reverse order of that of their prima.t 'disposition: IP,: -n cannot therefore reintroduce directly into the machine, to repeat a row, the row of accumulated matrices on bar 36.

   However, in accordance with the present invention, the dies can be reassembled automatically, if desired, in the order in which they were originally made and at a point where they can be easily fed back to the machine if desired. photograph them once more.



   This re-photographing mechanism returns the dies one by one from the unloading station 35 to the assembly elevator 12. For this purpose, a horizontal die return conveyor 50 is attached.
 EMI8.10
 runs from a point adjacent to the unloading station 35 to a point above the right end of the elevator 12. Near this end is a die return corridor 52, which is pivotally mounted.

  <Desc / Clms Page number 9>

 its left end so as to be able to be tilted from an inoperative horizontal position shown in figure 1 to a vertical position which is shown in figure 25 and in which its lower end is adjacent to the elevator 12.

   When the. corridor is in this position
 EMI9.1
 upright, it can receive the end dies from the conveyor 50 and guide them down into the elevator 12 and in the order suitable for the renewal of the photograph. When the line of dies has been reassembled in elevator 12, the latter rises again and the operations described above are repeated.

   In accordance with this
 EMI9.2
 modification of the invention, the triggering of the movement of the endless conveyors, with a view to transferring the head of the line of dies to the photographic station, triggering of the photographic mechanism
 EMI9.3
 and the release of the diJal rack: 1menation 27 to allow its displacement to the left, are carried out when the corridor 32 approaches its lowest position close to the elevator 12, The machine shown in FIG. 1 comprises various adjustment members allowing adjust the machine from several points of view. The way in which these adjustment members act has been described in its prmaipe, either in patent no. 987,279 already cited by reference, or in the patent application also mentioned above.

   If we start with the left side of Figure 1, we see that these adjustment members include a dial 47 for adjusting the line spacing, which allows to adjust the amplitude of movement of the film for each line, a dial 48 for adjusting of
 EMI9.4
 lenses, thanks to which one can modify a photographic enlargement of the characters of the elements, a gearbox 51, which is interchangeable with other gearboxes so as to be able to change the ratio between the movements of the rack 27 and the film holder 32 , a lever 53, the movement of which makes it possible to disengage the gearbox, 51, as well as the shaft 38 and its gears, a knurled disc 54,

   thanks to which we can adjust the initial position of the film holder 32 so as to achieve a precise alignment of the left margin of the column of characters for different degrees of enlargement, and finally the lever 46 which is arranged at the bottom left side of the machine and which, when lowered,
 EMI9.5
 allows the film to advance one line spacing within the film holder 32 to photograph characters from another line of elements - or to photograph a recirculated line again.

   The adjusters also include a lever 56, which can be moved vertically to actuate the line measurement and justification control mechanism 28, a margin control lever 58 for aligning a short line of characters, or on the line. left margin, or on the right margin, as desired, a main electrical contact 62 provided near the base of the machine and used to control the power supplied to the electric motor which drives the photographic mechanism, as well as the energy supplied to the camera light source, a rheostat button 60 and an am-
 EMI9.6
 associated father-meter 61 to adjust and indicate respectively l.f1intenB.ity of the current supplied to the light source,

   a button 64 for rotating a graduated drum 66 on which there are provided graduated scales corresponding to different dimensions of points, and finally a handwheel 68 which makes it possible to place
 EMI9.7
 an index 70 relative to the graduated drum 66 in order to indicate the dot dimensions of the desired line, and also to place the line length determining member 26 in the correct position on the rack
 EMI9.8
 de-fermentation 27a
As already indicated in the present description, the usual keyboard and magazine of the fully automatic or high-efficiency photocomposing machine of this type are replaced by a manual composition device.

   Any suitable and practical means can be used for storing the dies, for example the drawers of the desk on which the machine is mounted. The manual composition device according to the invention is clearly shown in Figures 5, 7 and 9 to 11 of the drawing.

   If we consider Figure 5, we see that this manual composition device comprises a slotted support designated as a whole by 80 and constituted by a base 82 provided with a longitudinal slit 84. a relatively high rear wall

  <Desc / Clms Page number 10>

 86 and a relatively low front wall 880 The base 82 and the walls 86 and
 EMI10.1
 88 form a channel in which is disposed a assembly carriage 90 provided with a longitudinal slot 92 coinciding with the slot 84 and a vertical gas end wall The carriage 90 has a right end 96 which is curved to facilitate manual movement of the carriage in relation to the support 800
 EMI10.2
 An adjustable guide 98 is mounted on the assembly carriage 90 and has a vertical wall 100 aligned with the wall.

  94 of carriage 90
 EMI10.3
 The guide 98 is fixed by adjustment on the carriage 90 by means of a rotary lock 102 and a stepped shoe 10 / Q. If one considers particularly FIG. 7, it can be seen that the locking member 102 comprises a handle 106 extending laterally. , and a pin 108 which projects downwards and which is screwed into the shoe 104. The upper step 110 of the shoe 10 $ = slid in the slot 84 of the support 80 and the lower step 112 constitutes a frame which prevents , in a manner which will be described in detail later, the separation of carriage 90 and support 80.



   The steps 110 and 112 have a height such that, when the locking member 102 is turned clockwise, the guide 98 is firmly clamped on the carriage 90, but the latter can slide freely. relative to the support 80. The guide 98 can be adjusted relative to the carriage 90 by rotating the locking member 102 in the direction
 EMI10.4
 counterclockwise enough for the pin 108 to slide freely into the slot 92 of the assembly carriage.



  The guide 98 of the carriage 90 is initially adjusted so as to provide between the walls 94 and 100 a space equal to the desired length of line.
 EMI10.5
 re ordering this setting is described below. When the desired clearance has been obtained, the locking member 102 is rotated in the direction of the
 EMI10.6
 clockwise so as to fix the guide and the carriage together and a line of dies is composed by hand in the space between the walls 94 and 100. The line composed of the dies is then introduced into the machine , as will be explained below.



   The line length adjustment mechanism, clearly seen in Figures 8, 9 and 11 of the drawing, is generally similar to that described in the above-cited patent. It includes a manual control wheel 64, an index 66 and a graduated drum 68.
 EMI10.7
 



  If we consider in particular Figure 9, we see that the flywheel 64 comprises a handle 120 s.9 extending forward and is provided, on its rear face, with a bevel gear 122 which meshes with a second bevel gear 124 wedged on a threaded rod 126. As can be seen in FIG. 11, the rod 126 is screwed into the member 66 carrying an index, and this member ends in a fork 128 which covers a guide rod 130; in this way, the index cannot rotate with the threaded rod. The rotation that is imparted to the rod
 EMI10.8
 thread 126 to 1? using the handwheel 64 moves the 1.9 index 66 laterally with respect to the graduated drum 68.



   As seen in Figures 8 and 11, the drum 68 carries at its periphery a series of engraved scales on which are marked the dimensions of the points, and the drum can be rotated by hand at
 EMI10.9
 means of the button 132 so as to present the desired scale at 1? to index 66, as was explained in detail in the patent cited above. The line 126 is connected by a series of shafts and gears, generally designated as 134, with the line length determining member 26.

   When the handwheel 64 is rotated so that the index 66 indicates the line length on the graduated drum 68, the member 26 is placed automatically, relative to the front wall G 'of the camera housing. , in the position determining the desired line length.
 EMI10.10

 a notch member 138 intended to receive the wall 94 of the assembly carriage 90 of the manual composition device. If we consider in particular Figure 9, we see that to adjust the guide 98 with respect to the as-

 EMI11.2
 this member is secured to the housing in any suitable manner, for example by screws 1520 As can be seen clearly in FIG. 11, the member 150 can receive the slotted support 80 of the manual dialing device 10 in such a manner. that this support slides on the member 150;

   support 80 is held in place in member 150 by a plate 154 fixed to member 150 by screws 156 (Figure 9) and covering the channel. As seen in Fig. 8, the composition device 10 slides into the member 150 in the form of
 EMI11.3
 channel until its left end hits a stopper 158 forming part of the elevator 12.



   The line composed of the dies is raised to the level of the
 EMI11.4
 feed channel 22 through the elevator 12, the construction of which is clearly shown in Figures 4, 6 and 8 of the drawing, As seen in
 EMI11.5
 Figure 6, the elevator in the form of a U in cross section; it comprises a front plate 160 and a rear plate 162 spaced from the front plate, the rear plate having on its edge. a.part 164. which protrudes laterally and serves to secure the two plates together. A handle 165 is attached to the front plate 160 to facilitate lifting of the elevator 12. The protrusion 164 of the elevator 12 is connected by a link 166 at the front end of lever 168 which is hinged to console 8 (Figure 4).

   A spring 170 fixed to the console 8 is also fixed at an intermediate point of the lever 168 so as to exert an upward force on the elevator 12. The tension of the spring 170 is chosen such that it almost balances, but not completely the weight of the elevator 12, of the link 166 and of the lever 1680 Thus, one can lift the elevator 12 by a light pressure of the hand, but it descends by its own weight to its lower position when it is lifted.

   The line composed of the dies is introduced into the elevator 12 by hand tightening the curved end 96 of the sliding carriage as-
 EMI11.6
 assembly 90 and pushing the left end thereof between the upper ends of the plates 160 and 162 until the upper step 110 of the shoe 104 comes into contact with the end of the slot 84.



  This has a length such that, when engaged by step 110, the compound line is placed correctly inside the elevator Coma as seen in figure 6, the dies are provided with upper lugs 172 and dj) lugs. lower 172 which extend laterally beyond the sides of wall 94 of the sliding assembly carriage. The plates 160 and 162 of the elevator 12 are provided with flanges 176 and 178 capable of coming into contact with the lower edges 174 of the. dies, and also respectively comprise flanges 180 and 181 above

 capable of engaging, and supporting, the upper ears 172 of the dies. Thus, when the elevator is lifted, the line composed of dies is "etipée & N. assembly guide 90 as seen in particular on ± 1g * e 7 .



   Turning now to Figure 1, it can be seen that the elevator 12, when it reaches its highest position, engages and switches the line delivery release lever 14, thereby releasing the line follower 20 and the lever. 16 of line delivery to allow them to move to the left o The connection between the lever 14 and the line follower 20 is shown in figures 15 to 17 o These two components are connected to each other by a frame 182 (figure 21) provided wheels 184 which roll on horizontal rails, upper and lower, serving to guide the line follower along a horizontal path.

   The wheels 184 roll forward in channels 185 arranged opposite each other in a frame of

  <Desc / Clms Page number 12>

 support 187 having in cross section the general shape of jinn C. If we return to Figure 1, we see that the line follower 20, when it moves to the left, drives the line composed of dies from the elevator 12 and along the feed channel 22 to the justification station 24, where the line follower is stopped by the line length determining member 26.



   If we now return to Figure 4, we see that the line delivery lever 16 is pivotally mounted at 186 on the console 8 and that it is pushed, counterclockwise, by a spring 188 relatively powerful which is connected at one end of the console 8 and at the other end to the delivery lever, at a point away from the pivot 186.

   The delivery lever 16 is provided near the pivot 186 with an arm 190 connected by a link 192 to an ordinary damping device 194 which dampens the movement of the delivery lever and prevents excessive shock between the line follower 20 and the line follower. 'member 26 at the end of the delivery stroke o A second damping device 196 is mounted on the console 8 and connected in a similar manner to the film support 32. This device 196 dampens the step by step descent of the film support 32 .



     Justification mechanism and its lock -
The justification mechanism is shown as a whole in Figure 1 and different parts are shown in detail in Figures 16 and 18 to 21. As seen in Figure 1, this mechanism comprises a movable rack 200, which can move vertically and carries a rider 202 adjustable laterally, and a thin rack 204 also carrying a rider adjustable laterally and designated by 2060 A control rail 208 brings together the two riders; it is articulated on the rider 202 and slidably mounted on the rider 206.



   If we now consider in particular the left part of Fig. 16, in which the line follower 20 is seen in the position it occupies after a large number of the matrices of a line designated by M2 have been removed from the justification station to be photographed, it can be seen that the line follower comprises two cooperating line clamping members shown in dotted lines. One of these members is a vertically movable wedge 210 which can slide in suitable guides of the follower 20 and carries a roller 212 at its lower end. This wedge 210 is provided with a slot 214 engaged by a finger 216 which cooperates with it to limit 1-9 amplitude of the vertical movement of the. corner.



   The other line clamp is a plunger 218 capable of sliding horizontally and pushed to the right by a spring 220. This plunger 218 has a head 222 capable of resting against the right end of the line of dies M2 at the justification station and carrying, inside the follower 20, a roller 224 able to come into contact with the inclined surface 226 of the wedge 2100 When the wedge 210 moves upwards, it pushes the plunger 218 to the left. which clamps the dies of the compound line against the end wall C mentioned above The amplitude of the movement of the head 222 of the plunger is equal to the line insufficiency mentioned above;

   therefore, the upward movement of wedge 210, which produces this movement of plunger 218 to the left, also measures the line insufficiency. The roller 212 and the wedge 210 are lifted by the rider 202 of the movable rack 200 by means. of a mechanism that we will now describe.



   The line insufficiency thus measured serves to modify the movement of the film holder so as to produce a justified line of characters on the film ,, By correctly setting the position of jumpers 202 and 206, it is possible to distribute this justification correction. , is. on the entire line, or on a part of the line chosen in advance.



  However, it suffices for the present presentation to consider the case where the justification corrosion is distributed over the entire line. In this case, the jumper 202 is placed on the rack 200 so that the swivel connection of the jumper and the control rail 208 is aligned with the height of the ge

  <Desc / Clms Page number 13>

   19 axis of roller 2120 As can be seen in FIG. 1, the control rail 208 is initially horizontal, but when the rack 200 and the rider 202 are lifted by the mechanism which will now be described, the control rail.
 EMI13.1
 control 208 is presented with a tilt angle proportional to the line insufficiency. When 1 line clamping operation is completed, the camera is triggered and the feed rack 27 is released., Then,

  dies are transported from the left end of the line
 EMI13.2
 compound, at the end wall C, up to the photograph position; when each die is removed, the spring 188 of the line delivery lever
 EMI13.3
 drives the line follower 20, 19 line determining member 26 and the creamillera 27 to the left and lowers the film holder 32 by a corresponding amount through the mechanism 38. When the fourth line follower 20 moves to the left, the roller 212 descends along the control rail 208 and thus lowers the wedge 2100. The roller 224 moves along the surface 226 and the head 222 of the plunger 218 is gradually retracted towards the body of the line follower.

   As a result of this withdrawal
 EMI13.4
 of the plunger 218, the line follower and the gear rack 27 move to the left, each time no die is removed to be
 EMI13.5
 photographed, of a length slightly greater than the thickness of the removed matrix and this small difference in displacement is transmitted to the film support in such a way that the justification correction is distributed over the entire length of the photographed line,
The mechanism for moving the rack 200 and the jumper 202 upward is clearly shown in Figures 18 to 21 of the drawing.

   As seen in the upper part of figure 18, the movable rack 200 is attached to a cross bar 230 which is supported by two vertical rods 232 and 234 (figure 20) The rods 232 and 234 can slide vertically in orifices provided respectively in bos-
 EMI13.6
 wise 236 and 238 fixed to the frame of the machàned, in a manner not shown in the drawing.

   The boss 238 has a stop 240 which limits the descent of the cross bar 2300 Under the bosses 236 and 238, the rods 232 and 234 are joined by a bracket 242 which carries a locking rod 244 directed downwardsa Two springs 246 and 248 respectively surround the rods 232 and 234 and are interposed respectively between the bracket 242 and the bosses 236 and 228 so as to push the cross bar 230 downwards against the stop 240.



   Returning to Figure 18, we see that the locking rod 244 passes through an orifice 250 provided in a locking member 252 which has at its left end a rim 254 projecting downward;
 EMI13.7
 190rgan 252 is supported by its rim 254 on a fixed stop 256.

   The locking member 252 is pushed in the clockwise direction of a .watch, so as to pivot eqtouc of the contact between the flange 254, and lablltée 256, par.a spring 258 which presses; 1.e-against the upper surface of the locked body. ge 252 and which is held in place by a screw 260;

   this screw goes through the res-
 EMI13.8
 comes out and the locking member and cut in a threaded hole of the stop 2560
Consequently, now in FIG. 21, it can be seen that the locking member 252 ends, at its end opposite to the flange 254, by a
 EMI13.9
 fork which receives 1-9 lower end of a control rod 262 hinged by a pin 264 to the locking member 2520 Near its upper end, the control rod 262 passes through a guide block 266, which is secured to the main machine frame in any suitable manner, for example by means of screw 268.

   The control rod 262 is provided at its upper end with a block 270 which slides along an adjacent edge of the guide block 2660.
The upper part of the control rod 262 cooperates with a bell return 272 articulated on the frame of the machine. The bell return 272 comprises an arm 314, by means of which the bell return is actuated in a manner which will be explained later, and an arm 274 in

  <Desc / Clms Page number 14>

 fork shape which partially embraces the control rod 262 between the upper block 270 and the part of the guide block 266 through which the rod passes.

   The arrangements are such that no rotation of the lever 272 in the counterclockwise direction causes the arm 274 to bear against the underside of the block 270 so as to lift the rod 262; conversely, a clockwise rotation of lever 272 allows rod 262 to move downward.



   The rise of the transverse bar 230 and its rack is effected by means of a control lever 280 actuated by hand and provided at its outer end with the button 56 already mentioned, this lever 280 being articulated by a pin 284 on the machine frame. At its lower end, the control lever 280 has a rounded boss 286 which is called

 EMI14.2
 



  During the period of time a line of element s is photographed, (and assuming no justification correction needs to be made), the crossbar 230 is locked in its upper position by the ac-
 EMI14.3
 cooperating brand of the locking rod 244 and the locking member 252. As can be seen clearly in Figures 18 and 19, the element 250 of the locking member 252 has a diameter slightly greater than that of the locking rod. locking 244. When the parts are in the position shown in Figure 18, with the locking rod 262 in its upper position and the locking member 252 substantially horizontal, no locking occurs.

   Under these conditions, if the button 56 is lowered to raise the crossbar 230, and if it is then released, the bar 230
 EMI14.4
 immediately returns to its lower position, in contact with the stopper, 2fit), under the inaction of the springs 246 and 248. The parts can be put in the Locking position by lowering the rod 262 to the position shown in FIG. 19;

   1? Locking member 252 then pivots around the flange 254
 EMI14.5
 until the upper front edge and the lower rear edge of the port 250 come into contact with points on the surface of the control rod 244 by pressing on those points. With the parts in the position shown in Figure 19, it is evident that a movement of the locking rod 244 upwardly relative to the locking member 252 tends to cause the latter to pivot in the direction. counterclockwise and thereby releasing the pressure between the upper and lower edges of the port 250 and the locking rod;

   on the contrary, if an effort is exerted to move the rod 244 downward with respect to the locking member 252, the pressure between the parts instantly increases to prevent such movement. Therefore, if the parts are in the indicated position
 EMI14.6
 shown in figure 19, and if we move 1-caliper 242 upwards by lowering the button 56, the caliper remains locked in its upper position when the button 56 is released until the locking member 252 turns in

 the counterclockwise direction shows under Inaction of an upward movement of the rod 262.



   --j The operating rod 262 is lowered, in order to place the parts in -on locking, by the line delivery movement of the line follower, and it is raised ,, to prevent locking of the parts, by
 EMI14.8
 the return movement of the line follower at the end of the photographing operation. We will now describe how the displacement of the: 1; control rod is achieved. It has already been pointed out previously that the control rod 262 is driven upwards and downwards by the pivoting
 EMI14.9
 of the doorbell return 272 (figure 15). This is itself actuated by a control bar 300 which can slide laterally on the main frame of the machine.

   The bar 300 ends at its left end with a fork which embraces a finger 302 fixed to the main frame, and it is provided at its right end with a slot 304 in which is engaged a finger 306 fixed to the main frame of the machine. bar 300 is pushed to the left

  <Desc / Clms Page number 15>

 by a spring 308 fixed to the main frame at 310 and connected, at its other end, to the finger 312 fixed to the bar 3000 The movement of the control bar 300 to the left is limited by the finger 306 engaged in the slot 304 on the right end.

   The longer arm 314 of the bell return 272 is arranged so as to be in contact with the finger 312 of the bar 300; thus, when the bar 300 moves horizontally, it rotates the bell diverter 272 so as to raise or lower the control rod 262.



   The arm 314 is normally kept in contact with the finger 312 by the weight of the control rod 262 and its associated parts, as well as by the spring 2680 The relation between the finger 312 and the arm 314 of the bell return 272 appears clearly in Figure 21.



   Turning now to the upper part of Fig. 21, it will be seen that the movable frame 182, on which the line follower 20 is mounted, carries an oscillating detent 316 which is hinged to the rear surface of the frame; the movement of this trigger in the anti-clockwise direction (looking at figure 21) is limited by the wall 318 of the frame 1820
Returning to figure 15, and in particular to its right part,

   it can be seen that the trigger 316 is shown pressed against the wall 318 of the frame 182 and in contact with an arm 319 which extends towards the barrier and which forms part of an adjusting member 320 itself fixed in an adjustable manner on the bar
3000 The organ 320 is slidable along the rear surface of the 1-end of the bar 300 and has a slot 321 in which a guide finger 322 attached to the bar 300 is engaged.

     The member 320 is fixed in an adjustable manner on the bar 300 by means of a screw 323 which extends forwardly through the slot 321 and which screws into the barie 300, so as to allow a relative lateral adjustment between the arms 319 and the bar 300 and consequently an adjustment of the right position of the bar 3000
With the parts in the position shown in Fig. 15, line follower 20 and its associated frame 182 are held against any leftward movement by line delivery release lever 14, and the line delivery release lever 14. trigger 316 maintains control bar 300 in its right-hand position by means of arm 319.

   Through finger 312, bar 300 maintains doorbell return 272 tilted to the right, as seen in the drawing, and doorbell arm 274 therefore maintains control rod 262 in its upper position. and prevents locking of the justification mechanism.



   As the line delivery release lever rotates as a result of raising elevator 12, line follower 20 and its associated frame 182 move to the left to the position shown in Fig. 160 From the start of the movement of the line follower 20, the trigger 316 moves away from the arm 319 and thus allows the bar 300 to move to the left under the influence of the spring 308; the doorbell 272a then rotates counterclockwise to lower the control rod 262 and place the locking mechanism in the operative position.

   As shown in the dotted line representation of Fig. 16 and Fig. 21, the swing trigger 316 contacts the upper part of the arm 314 of the doorbell 272, and then passes over this arm when the follower. line 20 approaches the end wall C.



   At the end of the photographing operation, line follower 20 is withdrawn to its right-hand position, as seen in figure 15, and this withdrawal of line follower 20 and its associated frame 182 allows the trigger 316 of. come into contact with the arm 314 of the bell return 272 to cause it to rotate clockwise, and lift. worm the control rod 262 thus unlocking the justification mechanism. When the line follower reaches its right position, the trigger 316 again comes into contact with the arm 319 of the bar 300 and pulls the latter to its right position shown in Figure 15.

   The finger 312 then maintains the bell return 272 inclined to the right in order to maintain the control rod 262 in its upper position, that is to say in its unlocked position.

   The justification device of this machine is constructed in such a way that the short lines can be placed either at the left margin of the character column (flush operation on the left), or
 EMI16.1
 to the right margin of the character column (right flush operation) and also allows normal justification of an entire line.
 EMI16.2
 To perform the right-hand trimming operation, the crossbar 230 is left in its lower position, and this operation is performed in the present machine simply by not lowering the lever 56.

   In the initial description of FIG. 1, reference was made briefly to the lever 58 which, in its upper position, performs the normal justifying operations.
 EMI16.3
 The left flush operation is performed in the present machine by bolting the control rail 210 to the cross bar 230 so that this rail remains horizontal when the cross bar is in its lower position and in its lower position performs the left flush operation. 230 is raised
The structure for bolting the control rail to the crossbar 230 has not been fully shown in the drawing of the present patent application. However, part of this structure is shown in figure 18.

   If we refer to this figure, we see that the lever 58 is indicated in phantom and that it is mounted on a rotary shaft 330 to which is fixed a toothed wheel 332 engaged by a chain 3340 When we move the lever 58 of its high position to its low position, toothed wheel 332 rotates and drives chain 334 to slide a bolt (not re-
 EMI16.4
 shown) carried by crossbar 230 until it comes into contact with control rail 208;

   as a result, the control rail 208 raises horizontally when the lever 280 is lowered to raise the crossbar 2300 When the control rail is raised, (figure 16), the line of elements M2 is tightened as previously explained , but when
 EMI16.5
 the lifting rack 27 is released, the roller 212 moves in a horizontal line and no justification correction is therefore applied to the movement of the film holder.,, When the lever 58 is raised to its up position, the chain 334 moves in the opposite direction to remove the bolt (not shown) from the control rail 206,

   in order to allow the normal operation of justification which was explained previously,
 EMI16.6
 The photographic apparatus of the present machine is essentially the same as that described in the patent cited above by reference.



  It comprises two endless chains 646, one of which is shown partially in the upper right-hand part of figure 30 and serves to individually lift the dies of line M2 to a photograph position where the characters carried by the dies are photographed and then to a discharge position where they are discharged.

   Thus, the present machine includes apparatus for returning the dies from unloading station 35 to elevator 12 in a suitable order for photographing them again to repeat a line. Referring to Figure 25, we see that the conveyor 50, made in the form of a belt without. end is mounted on spaced pulleys 336 and 338, the pulley 336, being, located near the unloading station 35 and the pulley
 EMI16.10
 338 being located approximately above the right-hand end of elevator 12.

   The belt is kept taut on the pulleys 336 and 338 by a current belt tensioning device 340

  <Desc / Clms Page number 17>

 
Turning now to Figure 28, we see that the dies are unloaded at the unloading station by a pusher 342, the operation of which has been disclosed in the above-referenced patent. The advancing position of pusher 342 is shown in line. dotted and designated by the reference number 342a.

   A block 344 is disposed above the conveyor 50, near the charging station 35; this block comprises a curved reflection member 346 which guides or deflects each die so as to bring it into the desired horizontal position on the conveyor 500
As previously indicated, a revolving corridor 52 of re
 EMI17.1
 A tower of the dies is provided at the discharge end of the conveyor 50 to guide the dies to the elevator 12. Referring to Figures 30 and 31, it is seen that the lane 52 has two spaced side walls 348 and 350 connected! another by a cross member 352 at the upper end
 EMI17.2
 re of the corridor, and by a cross member 354 at the lower end of the corridor.



  This is mounted to pivot on a shaft 356, which is itself supported in a channel 358 forming part of the frame of the machine; the lane is rotatable around shaft 356 from the horizontal position shown in Figure 1 to the vertical position shown in Figures 30 and 31.



   If we refer in particular to Figure 31, we see that two spaced guide members 360 and 362 are fixed to the side wall 350 of the corridor 52; these guide members define a guide slot 364. The other side wall 348 of the corridor 52 is provided with a similar guide slot (not shown) Under the lower end of the guide grooves 364, there is a organé deflector 366 inclined at a suitable angle to guide
 EMI17.3
 the dies To the 12 "elevator, A similar deflector 368 (Figure 30) is attached to the side wall 348 of the aisle 520 At the base of the aisle 52,
 EMI17.4
 that is, at its discharge end, there is a star wheel 369.

   mounted on a shaft 370, which is rotated by means which will be described later, in order to ensure correct positioning of the dies in the element.



   The dies are transported by the conveyor 50 to a guide channel 372 formed in the channel 358, and they are guided towards the upper end of the guide slot 364 and the corresponding slot provided on the side face 348 of the corridor 52. The dies then fall through the corridor and pass between the deflector members 366 and 368 and the arch 374 urged by a spring to finally arrive at the star wheel 369 which pushes them one after! Each other in! S ' elevator 12.



   The conveyor 50 is driven by the pulley 338, while
 EMI17.5
 the star wheel 369 is driven, via a shaft 370, using means which will now be described., The power required to

 the drive of the conveyor is provided by an electric motor 376 shown in dotted lines near the base of figure la. If we consider the lower part of figure 30, we see that this motor is connected by a gear reducer to one, shaft 378 on which is caléenne pulley 3800
 EMI17.7
 This pulley 380 drives, via a belt 382 and a pulley 384, a shaft 386 rotatably mounted in a fixed block 388 fixed to the channel 3580 Considering FIG. 26,

   we see that 1? shaft 386 crosses a pulley 338 which is wedged on it; the rotation of the shaft 386 therefore drives the pulley 338 and the conveyor 50. A toothed wheel 390 is also fitted.

   The pulley 400 is fixed on the shaft 370 on which is also mounted the

 star wheel 369, so that this is driven through pulley 396, belt 398, pulley 400 and shaft 370.



   Considering again figure 31, we see that the matrices
 EMI17.10
 introduced into the elevator 12 by the star wheel 369 are assembled against a finger 402 which forms part of a sliding assembly carriage 404 pushed to the right by a spiral spring device 406 similar to those used on typewriters. 1) free end 408 of the device to

     this end 408 passes over a idler roller 412 mounted between the hook 410 and the spring device 406. The spring tension in the device 406 can be adjusted by rotating a shaft 414 carrying a worm 416 which meshes with a toothed wheel 418 provided inside the device 406.



   If reference is made more particularly to FIG. 32 and to FIG. 31, it can be seen that the sliding assembly carriage 404 is provided with a brake designated as a whole by 420 and comprising a brake arm 422 pivotally mounted on a axis 424. The carriage 404 passes through an opening 426 of the arm 422 and this opening is slightly wider than the carriage.

   The brake arm 422 is urged in a clockwise direction by a spring 428 connected to the arm and a fixed pin 430. The construction is such that the carriage 404 can be easily moved to the left, but is held against it. any movement to the right by the frictional forces exerted on it by the front left and rear right portions of the side walls of the opening 426.



   The brake 420 can be released, either by hand or automatically. A tab 432 extends laterally near the front end of the brake arm 422; this tab can be lowered by hand to rotate the arm 422 a small angle counterclockwise, thus allowing the spring 406 to bring the carriage 404 back. bottom of FIG. 31, it can be seen that, for the automatic release of the brake 420, a lever 434 pivotally mounted at 436 and pushed by a spring 438 against a stop 440 is provided. The lever 434 is provided at its end, on the right, a finger 442 which engages in a slot 444 of a rocking arm 446 articulated at 448.

   The upper end of the arm 446 is so arranged that when the lever 434 is lifted it engages a finger 450 attached to the rear of the brake arm 422 and rotates the latter counterclockwise. a watch to allow the spring 406 to bring back the carriage 404.



   Lever 434 is lifted by moving elevator 12 upward. The left end 452 of lever 434 is located above. a control surface 454 provided on the elevator 12, which surface contacts the end 452 as the elevator 12 rises. End 452 is far enough above surface 454 to allow the line of dies to clear the top of finger 402 before carriage 404 is released. .



   As indicated above, the present machine is suitable, either for the type of operation in which the dies are collected on an assembly bar 36 after having been photographed, or for operation with repeating lines. Referring now to Figures 23, 28 and 29, we see that the plate 34 can be lowered to a horizontal position (Figure 29) using a handle 648 provided with a hook 650 (Figure 23 ) in order to engage a latch 652 (Figure 1);

   in this position the bar 36 is aligned with the unloading station 35 of the machine and the dies are collected on the assembly bar from where they can then be removed in any suitable manner, for example by means of the device. dialing manual 10 shown in Figure 1.



   When the plate 34 is lowered, the guide block 344 is withdrawn out of the path followed by the dies, so as to leave a free space allowing the bar 36 to be moved into the path of the dies; a description will now be given of the structure which thus allows the guide block 344 to be erased.



   Looking at the upper right-hand portion of Figure 30, it will be seen that an attached support plate 456 is attached to the machine frame; this plate is provided with guide members 458 responsible for guiding a block 460 slidably mounted on the plate 456. The sliding block 460 comprises a vertical wall 462 on which the guide block 344 is fixed (figure 23) A pin 464 is screwed in the left end of block 460 and it is

  <Desc / Clms Page number 19>

 connected by a spring 466 to the channel 358 of the machine frame so that the block 460 is pushed to the right (looking at figure 23) to place the guide block 344 above the return conveyor 50 matrices.



   Reference will now be made to Figures 26 and 27. A rod 468, on which is mounted a small roller 470, is formed on the block 460 and near the wall 462 (see also Figure 30). The roller 470 (Figure 23) is engaged by a bar 472 attached to the plate 34 of the accumulation bar. This roller is spaced appreciably from the pivot 474 of the plate 34; thus, when the plate 34 is moved to its horizontal position, the bar 472 and the roller 470 cooperate to retract the slide block 460, despite the tension of the spring 466 and therefore to remove the guide block 344 from the path. followed by the unloaded matrices.

   Therefore, when the plaque
34 is in its lower position (Figure 29, the bar 36 is placed in the die receiving position, while, when the plate 34 is in its highest position (as in Figure 28), the guide block 344 is in position to deflect the dies down and bring them onto the conveyor
50.



   As explained in the French patent cited above as a reference, the camera mechanism comprises various parts driven by an electric motor via a clutches When the line composed of the dies has been moved to at the justification station
24 and when the line measurement and justification control operations have been carried out, the camera clutch is engaged to successively drive the dies to the photography station 33 (figures 1 and 30). refers to figure 26 and in particular to the left part of this figure,

   it can be seen that the camera mechanism is engaged by moving a rod 4760 to the left A bell return 478 is mounted on the plate 456 by means of a screw 480 so as to move the rod to the left 4760 The bell return 478 comprises an arm 482 capable of attacking the rod 476 and an arm 484 in which is engaged a screw 486 capable of being attacked by the wall 462 of the sliding block 4600 Thus, when the plate 34 is lowered and with block 460 retracted, bell deflection 478 rotates so as to move rod 476 to the left and therefore start the camera mechanism ;.



   During the row repeat operation, the plate 34 remains in its upper position and a separate mechanism is therefore provided to start the camera mechanism in this case. When the machine is prepared to perform the repeat of a row, the camera is started by pivoting the die return lane 52 towards its lowest position, again considering Figures 26 and 27, it can be seen that the bell return 478 can rotate, not only by removing the block 460, but also by means of a rod 488 provided at its left end with a head 490 capable of striking the arm 482 of the bell return. doorbell 478.



   Turning now to Figure 30, we see that the rod 488 can slide at its right end in a post 492 rising from the plate 456. The left end of this rod 488 is attached to a swing arm 494 mounted on a shaft 496 which can oscillate in a block 4980 A driving arm 500, provided with a contact screw 501 at its outer end, is also wedged on the shaft 4960 The corridor 52 is provided with a finger 502 'dispodé so as to be able to come into contact with the screw 501 when the corridor approaches its vertical position.

   Thus, when the lower end of the corridor 52 approaches elevator 12, the finger 502 rotates the shaft 496 so that the rod 488 moves to the right and rotates the bell return 478, in order to push. to the right rod 476 and start the camera mechanism.



   It can also be seen in Figure 30 that the rod 488 is pushed to the left by a spring 504 which surrounds the rod 488 and which is interposed between the upright 492 and the upper end of an arm 506 wedged on a shaft 508. A collar 510 is attached to rod 488 in order to maintain the

  <Desc / Clms Page number 20>

 output 504 compressed It appears that when the finger 502 of the lane 52 moves the rod 488 to the right, the shaft 508 rotates clockwise at the same time as the camera start rod 476 is actuated .



  The rotation of the shaft 508 frees the feed rack 27, through a mechanism which will be described now, at about the time of starting the camera. Considering FIGS. 23, 24 and 25, it can be seen that the supply rack 27 has an orifice 512 in which a locking bolt 514 can be engaged which can move axially. This bolt 514 comprises a lateral finger 516 capped by the fork provided at the lower end of the arm 518 of a bell transmission 520 capable of rotating around a pivot 522.

   The other arm 524 of the bell return 520 is articulated on the lower end of a rod 526 provided at its upper end with an extension 528 of reduced diameter which cooperates with the main part of the rod 526 to form an annular shoulder. 530. A spring 532 connects the arm 524 to the frame of the machine; this spring is normally under tension and tends to push the locking bolt 514 into the hole 512 of the supply rack 27. A lever 534 is attached to. the front end of the shaft 508 which has already been mentioned with reference to figure 30; this lever 534 is arranged so as to be able to engage with the shoulder 530 of the rod 526.

   The left end of the lever 534 is constituted for this purpose by a fork which embraces the extension 528 of the rod 526 (FIG. 24). .



   To prevent the feed rack 27 from being inadvertently released, a mechanism is provided to prevent removal of the locking bolt 514 until the compound line has been moved and has reached the justification station 24. Near from the lower end of the rod 526 there is a part 536 which can be arranged so as to prevent the lowering of this rod and the withdrawal of the locking bolt 514; this part 536 can pivot around an axis 538 to come into a position allowing the lowering of the rod 526 and the withdrawal of the locking bolt 5140 A wedge-shaped part 540 is attached to the lower end of the axis pivot 538;

   a spring 542 is connected to the wedge 540 so as to tend to urge the part 536 under the rod 526. The pivoting of the axis 538 clockwise, to move the part 536 away from. below the rod 526, is effected by a bar 544 capable of pivoting to the left to rotate the wedge 540. The pivoting of the bar 544 is produced by the engagement of a part of the line follower 20 with this bar when the Line follower approaching Justification station.

   As noted above, movement of die return corridor 52 to its lowest position rotates shaft 508, which brings lever 534 into contact with shoulder 530; this lever thus lowers the rod 526, and requires that the locking bolt 514 is released from the feed rack. Therefore, when the lane 52 reaches its low point, the camera mechanism starts and the feed rack 27 is unlocked at about the same time.



   When the machine is used to collect the dies on the bar 36, the. corridor 52 remains in its horizontal position. Under these conditions, the feed rack is unlocked when the upper end of the extension 528 of the rod 526 is lowered by the plate 36, moving to its lower position.

   Lowering the plate 34 therefore starts the camera mechanism and at about the same time unlocks the feed rack 27
Considering in particular Figure 12, it can be seen that the bar 544 is articulated at spaced points on the lower ends of two parallel links 602 and 604, which are themselves articulated at their upper ends on the main frame of the machine. so that the bar 544 can oscillate freely in the lateral direction The line follower 20 is provided with an arm 21 which extends forwards;

   when the line follower approaches the line length determining member 26, this arm 21 lifts a latch 29 pivotally mounted on the member 26 and passes under this latch, thus locking the line follower on the organ 26. The

  <Desc / Clms Page number 21>

 latch 29 is aligned with bar 544; when it is lifted by the arm 21 of the line follower, it engages the bar 544 and rotates it up and to the left. Bar 544 then engages and rotates wedge 540, as previously indicated, to place the lock release mechanism.
 EMI21.1
 the rack in the desired condition allowing the rack to be released when the plate 34 is lowered.



   To maintain the bar 544 in its left position until the line follower has been retracted after the end of the photographing operation, a trigger mechanism is provided as shown in Figures 12, 13 and 14. As as can be seen clearly in FIG. 12, the upper end of the link 604 is provided with a shoulder or notch 606 (FIG. 13) in which a pivoting arm or trigger 6080 can engage. This arm 608 is articulated between its ends, on one end of a rod 610 which can slide axially in the support fittings 612 and 614.

   A res-
 EMI21.2
 spell 616 is interposed between the fitting 612 and the left end of the rod 610 and surrounds this rod; this spring 616 therefore tends to push the rod to the left. This carries at its right end a block 618 provided with a finger 620 extending downwards and capable of engaging the upper part of the line follower 20 (FIG. 14). The way the finger
 EMI21.3
 620 comes into contact with the shoulder part of the line follower 20 shown in particular in FIG. 5. When the line follower is in its right position, the parts are arranged as in FIG. 12, with the trigger 608 released from the rod 604.



   When the line follower 20 begins its line delivery movement, it is seen that the released rod 610 moves to the left under the inaction of the spring 616 and that the front end of the arm 608 comes to rest elastically against the rod 604, at a point slightly below 1-notch 6060 As it approaches justification station 24, the line follower allows latch 29 to swing bar 544 to the left.
 EMI21.4
 che, and as a result of this movement, the notch 606 of the link 604 is slightly lowered, which allows the front end of the arm 608 to engage in this notch and thus to maintain the bar 544 in the gaucho position.



   Returning to Figure 1, it can be seen that the conveyor 50 and the star wheel 369 of the return corridor 52 are driven by a motor
 EMI21.5
 electric 376 as explained previously The 376 motor is powered by current ¯ by an appropriate source and by the intermediary of a circuit comprising a driver 546 connected directly to the motor and a conductor 548 connected to mm, eromeord.tat 550 connected to it - even at the motor by, a driver 5520 The microswitch 550 (also shown in figure 31) is provided

 of a contact button 554 capable of being engaged by the corridor 52 when the latter is in a horizontal position The electrical connections are such that, when the corridor 52 is horizontal, the circuit of the engine 376 is cut, and when the corridor 52 swivels towards the bottom,

   it moves away from the -contact button 544 to close the circuit and start the engine 376, and consequently the conveyor 50 and the star wheel 3690
A lock has been provided to keep the corridor 52 in a horizontal position. Referring in particular to FIG. 2, it can be seen that this lock 556 constituted by a curved spring is fixed at its lower end on the frame of the machine, and that it leans on the underside of the corridor 52. To release the corridor and allow it to pivot downwards, we
 EMI21.7
 manually lower the latch 558, i.e. push it to the right while looking at figure 2.



   Referring to the lower left portion of Figure 30, it can be seen that a latch 558 is provided to lock the aisle 52 in.
 EMI21.8
 its lowest position. The lock 558 pre..n return a bell capable of turning on a fixed pivot 560 and comprising the arms 562, 564 and 566. The arm 564 is connected by a spring 568 to the frame of the machine; this spring tends to rotate the bell return counterclockwise around pivot 560.

   The rotation of the sonnet-

  <Desc / Clms Page number 22>

 counterclockwise is limited by

 a stopper 570 on which can S9 push the arm 5620 As the lane 52 approaches its lowest position, the arm 566 of the bell deflection moves behind the lane under Inaction of the spring 568 until the moment when the arm 562 comes hit stop 570; this way the corridor is closed

 rusty with its discharge end next to the elevator 12.



   The latch 558 is unlocked by the return movement of the line delivery lever 16. This lever comprises a curved arm 572 capable of coming into contact with the arm 564 when the lever 16 approaches its retracted position, and thus of moving the arm 566 to release it from behind the corridor 52, thus unlocking the latter.



   The line delivery lever 16 and the line follower 20 can be retracted by hand by means of a ball knob 42 mounted to

The bar 574 is arranged to engage the lane 52 when the line follower 20 is retracted The arrangement of the parts is such that, when the delivery lever and the line follower approach their retracted position, the arm 572 of the shift lever. delivery unlocks lane 52, and bar 574 then engages lane and rotates it slightly

 away from the elevator 12, the new position of the corridor being indicated in phantom in FIG. 31. With this arrangement,

   corridor 52 cannot be locked again to start the mechanism

 of the camera, until Pelevaur 12 n9 is lifted again to release the line delivery lever and line follower and bring a line of dies to justification station 24.



   Referring to Figure 30, and Figure 6, it is seen that the elevator 12 is provided with a door 576 which can be pivoted towards

   The electrical circuit of the present marine is shown in figure 22. It can be seen in this figure that an ordinary plug 580 of a socket outlet, capable of being pushed into a corresponding ordinary socket, is connected by a conductor 582 at one end. the primary of a transformer 584, and by a conductor 586, an electrical contact 62 and a conductor 588 at the other end of this primary. Contact 62 is precisely the manual starting contact shown in figure
 EMI22.7
 gure 1.

   Reference number 590 designates the electric motor driving the camera; this motor is connected to conductors 582 and 588 by respective conductors 592 and 5940

   If we consider in particular-Figure 12, we see that a control member 600 of the electrical contact
 EMI22.10
 tri-, l - * 5t pivotally mounted on the upper pivot of the rod 604; when the bar 544 pivots to the left, this member 600 moves upwards and
 EMI22.11
 actuates a contact 622 to increase the energy supplied to lamp 596.



   If we now return to Figure 22, we see that no end of the secondary of transformer 584 is grounded, while the other end is connected by a conductor 624 to a resistor 626 itself connected to a fixed point 628 of contact 622 The other fixed point 630 of the contact 622 is connected, through the intermediary of the rheostat 60 and the conductor 624, to the secondary of the transformer 5840 The various locations which can be given to the rheostat 60 are indicated in Figures 1 and 12 .



   The lamp 596 has a filament 632, one end of which is connected to earth while its other end is connected by a conductor

  <Desc / Clms Page number 23>

 
634 to the movable member 636 of the contact 6220 The arrangements are such that., When the pivoting bar 544 is in its lowest position, the movable member 636 is in contact with the fixed point 628 and the lamp is supplied with current through resistor 626; the lamp therefore consumes relatively little current.

   On the contrary, when the bar 544 is moved upwards and to the left by the line follower 20, the movable member 636 comes into contact with the fixed point 630 and the lamp 596, which is then supplied via the rheostat 60 , operates at a relatively high intensity o The light intensity of the lamp can be adjusted using rheostat 60 during photography o The light intensity of the lamp
596 is measured by a selenium photocell 638 ... which is connected by conductors 640 and 642 to an ammeter 661, the replacement of which is shown in figure 15.

   It is evident that when the line follower
20 is withdrawn at the end of the photographing operation, the rod 610 is retracted to disengage the trigger 608 from the link 604. The bar 644 then pivots downward to its lower position and the movable member 636. touches the fixed point 628, thereby reducing the energy supplied to the lamp 60, until the forward line follower line delivery movement occurs again.



   The operation of the machine should emerge fairly easily from the preceding description, but it nevertheless appears desirable to briefly summarize the successive stages of this operation in the order in which they occur. The machine is first set up for the dimensions of the characters to be printed expressed in points and for the length of line desired.



   The order in which you perform these initial settings does not matter.



   These adjustments are as follows, with reference to FIG. 1 g a - adjust the position of the graduated drum 66 so as to bring into the position of cooperation with the index 70 a graduation bearing the appropriate dimensions expressed in points; b - turn the handwheel 68 so as to have the index 70 indicate the desired line length on the graduated drum 66; the rotation of this flywheel, as indicated above, also places the member 26 for determining the line length in the appropriate position on the supply rack 27;

   c- set the dial 48 of the lenses for the appropriate dimensions in points: move the dial 54 for adjusting the margin to obtain the appropriate dimensions in points, e - insert the appropriate gearbox 51 in the train d drive of the film support;

   f - placing the line spacing dial 47 in the desired position to give the film the correct line advance movement; g - adjust the justification mechanism 28 by placing the justification conditioning lever 58 in the appropriate position? If one wants to compose tables, further settings of the justification device 28 are necessary as explained in the patent application cited above in reference. When all these adjustments have been carried out, the start contact 62 is actuated to supply energy to the machine.



   A line of matrices M-i is composed in the manual device 10 and the latter is introduced into the machine. The compound line is then introduced into the elevator by moving the sliding member of the manual composition device. The elevator 12 is then raised to remove the die line from the slide member and the device 10 is removed from the machine.
When the elevator reaches its upper position, it actuates the release lever 14; line delivery lever 16 and line follower 20 then move the dialed line to justifying station 24.

   Movement of line follower 20 to the left rotates

  <Desc / Clms Page number 24>

 bar 544 to the left (Figure 24), as a result wedge 540 rotates and places the feed rack unlocking mechanism in the desired position to unlock that rack.



   When the line follower 20 reaches the line determining member 26, it locks with it, and the compound line is then placed at the justification station 24 between the line follower 20 and the end wall. C. The button 56 is then lowered to measure the line insufficiency and the machine is ready to photograph the c. characters of the matrices.

   If we want to collect the dies on the assembly bar 36 after the photographing operation, it is then necessary to lower the plate 34 of the accumulation bar; this operation causes the camera mechanism to start and also unlocks the supply rack 27. It is then that the photographing operation is carried out which has been fully described in the French patent cited above by reference, Les matrices are successively moved upwards from the justification station 24 to the photographing station 33 by transport chains, and they are then raised to the unloading station 35, from where they pass over the accumulation bar 36.

   The film support 32 moves downward by successive advances, the location of which is controlled by that of the movement of the supply rack 27.



  The magnitude of each feed, as already noted, is determined by two factors, the thickness of the individual removed from the head of the line and the justification correction to be applied.



   When the line length determining member 26 reaches the end wall C, the line follower 20 is automatically unlocked from this member. The button 42 of the line follower is then seized and the latter is brought back to its right position. As explained in the French patent cited above by reference, the line follower puts back in place, during its withdrawal movement, the supply rack 27 and the film support 32. In the case where the passage 52 die return is in its lower position, removal of line follower 20 unlocks this lane and rotates it away from elevator-12.



   When the line follower has been returned to its right position, and has been locked by raising the right end of lever 14, plate 34 is lifted from the accumulation bar, disengaging the clutch. drive the camera, and releases the feed rack locking mechanism to allow bolt 514 to enter hole 512 in the rack and lock the rack.

   The elevation of the plate 34 also allows the spring 532 (Figure 24) to lift the rod 526; the spring 542 then moves the part 324 'to bring it under the rod 526, so as to prevent the lowering of the plate 24, the starting of the camera mechanism and the release of the supply rack 27, until 'that the line follower has placed another line at the justification station.



  The discharged dies are removed from the accumulation bar 36 and returned to the store. Knob 46 is then lowered by hand to advance the film and the machine is ready for another cycle of operation.



   In the event that the machine is arranged to perform the line repeat operation, the accumulation bar plate is left in the upper position. The operation is the same as that explained above until the operation consisting in lowering the button 56 of the justification apparatus 28. Then, the latch 556 of the die return passage 52 is lowered and the passage is pivoted. downward as it approaches elevator 12. The initial movement of lane 52 operates electrical contact 550 to start motor 376 which drives conveyor 50 and star wheel at the discharge end of the lane.

   As the lower end of lane 52 approaches elevator 12, lane finger 502 rotates shaft 496 to move rod 488, start the camera mechanism, and unlock power rack 27. The lane is then locked against the elevator 12 by the lock 558 and the photograph of the characters of the dies proceeds as before.

  <Desc / Clms Page number 25>

 



   The dies arriving at the unloading station 35 are pushed by the pusher 342 against the guide block 344 guiding pins onto the conveyor 50; they are then transported to the upper end of the lane 32. The dies are then guided one behind the other through the lane 52, then pushed successively into the elevator 12 by the star wheel. Since the dies are assembled in

 The elevator in the order they were unloaded at the unloading station, they are in the correct order for J, a, a..photographing again. When they have been reassembled in the elevator 12, the line follower is removed, as previously explained, in order to unlock the lane 52.

   When the line follower is in its fully withdrawn position, it rests against the lane 52 and maintains the latter away from the elevator to the outside, as can be seen particularly clearly in Figure 31. If one wishes to repeat the dialed line one more time, the elevator 12 is raised to allow the line follower to advance the line again to the justification station, and operations. described above are repeated. If a single character or only a few characters must be changed in the composed line, the door 576 of] .- 'elevator 12 can be opened and the ma-
