(Cl. S35-4.5)

Claims.

This invention relates to an improved record controlled photographic recording machine, and more particularly to a machine adapted to the photographic recording of characters in one or more colors.

The type oi machine to which this improvement relates is shown in U. S. Patent No. 2,346,251 to James W, Bryce. The machine of the Bryce patent achieved photographic recording under control of perforated record cards by selectively flashing gaseous discharge tubes in timed relation with the rotation of a character drum which is transilluminated by the ashing tube, thereby exposing a photographic lm on which the record is made.

It is a general object of this invention to provide a machine of the type indicated to record in more than one color under selection of record sources such as perforated record cards from which are derived the data to be recorded.

It is a further object of the invention to provide a machine for recording photographically in more than one color on a single photographic record medium.

It is a further object of the invention to provide for the simultaneous recording in selected columns of a record medium, and particularly to provide such recording in different colors.

It is another object of the invention to provide individual column control of color recording in recording operations using a photographic recording medium.

A still further object of the invention is to pro- .vide auxiliary color control mechanism cooperating with flash tubes during the recording operation so that one or more columns of data may be recorded simultaneously in different colors.

It is still a further object of the invention to provide a plurality of differently colored recording devices which may be selectively brought into operation under control of the record source.

It is also an object of the invention to provide means for presetting a color recording device which will result in the color recording of data in preselected columns of the recording film.

The objects of the invention are attained by providing a machine having a card handling and sensing section through which perforated record cards are passed, and from which a recording section is controlled, Basically the recording section includes a camera unit having suitable lens structure through which a color sensitive photographic iilm may be exposed as it is passed from a feed spool to a take-up spool in synchronization with the passage of cards through the card handling and sensing section. The recording section includes a rotatable character drum which is opaque but for columns of characters formed therein through `which gaseous discharge lamps within the drum are adapted to illuminate the photographic lm, the rotatable character drum being rotated in synchronism with the passage of a card through the sensing section so that `as a perforation is sensed in the card a corresponding drum character is positioned at a transilluminating slot in front'of the gaseous discharge lamp. Each drum has a separate discharge lamp related to each character column in the periphery of the drum, and the lamps are selectively red under the control of card perforations.

The color recording herein to be described may be achieved in a plurality of different ways. In one form of the invention color screens are provided on movable strips which correspond in position and number to the character columns in the wall of the rotating character drum. The color screens of the respective strips may be brought into alignment with the character of the drum at the exposure position under the selective influence of record cards being processed. When a color screen is positioned at the exposure zone of any given column7 the recording on the color sensitive photographic iilm will be in a corresponding color.

In a modified form of the invention a plurality of character drums are provided, specifically two such drums, and the discharge lamps of the respective drums are selected to produce under their natural illuminating power a desired color in the record film. Thus, in the example that is to be described more specically hereinafter, it is proposed to provide neon lamps in one of the character drums, thereby producing on the record iilm a red recording, and mercury vapor lamps in the second drum, the rays of the mercury vapor lamps being effective to produce a bluish white recording on the recording film. In the modified form of the invention the drums and their associated lamps are also under control of record cards being sensed in the record card handling and sensing section, and the drums and their illuminating lamps are consequently automatically and selectively operated to produce the desired color recording under record card control.

The manner in which the invention is practiced will appear more particularly as the description thereof proceeds with reference to the drawings forming a part of this application and in which drawings:

Referring now particularly to Fig. l, the machine in general comprises a record handling and record reading section Ill and a recording section or unit I2. Suitable shafting Connects the recording section and the record handling and analyzing section whereby the operative devices of the respective sections may be driven by a motor I4. The motor I4 through conventional worm gears and shafts is adapted to drive a main drive shaft i6. The drive shaft I6 directly drives parts in the `recording section, as will be subsequently described. It also drives a plurality of so-called C cams, specifically herein referred to as the cams C`I through C-4 which are keyed to the shaft. Attached to the shaft I6 is a gear I8 which drives a gear 20. Fixed to the gear is a one-revolu tion clutch mechanism 22 which is freely rotatable on a shaft 24. A clutch dog 26 is pivoted to an arm 28 which is fixed to the shaft 24. The clutch dog 26 is adapted to be tripped into engagement with a notch in the clutch plate 22 upon energization of a card feed clutch magnet 3Q. the shaft 24 are two distributing commutators CD-I and C20-2. Also attachedA for rotation with the shaft 24 are cams CF-I through CF-I IA. Gearing 32 transmits drive from .the shaft 24 to a main drive shaft 34 of the cardv handling and sensing section. The card handling and sensing section is of customary construction, and it includes a supply hopper 36 and a stacker or discharge hopper 38. The card handling and sensing unit is also provided with driven card feed rolls which are driven by helical gearing 4G. Within the card sensing section isa conventional card picker which is adapted to pick cards one at a time from` the bottom of a card stack in the hopper 36 and advance such cards into the bite of feed rolls, whereafter the cards pass between sets of Contact rollers 42 and 44 and related sensing brushes B-I and B-2, respectively, for detecting perforations therein. The cards passing through the card sensing section also come into contact with card levers 4b and 48. After the cards have been analyzed in the card sensing section, they are discharged into the receiving hopper 33. The contact rolls 42 and 44, their related sensing Driven by and secured to r brushes B-I and B-2, respectively, and the card levers 46 and 43 are .shown in Fig. 8 of the drawings, and their particular disposition in the card sensing section is disclosed in Fig. 7 of the Bryce patent noted above.

yRecordimg unit i2 includes a suitable base 5@ which has attached thereto a pair of side plates 52 and 54, and by particular reference to Fig. 5, it may be seen that suitable bearings in the side plate 52 afford a journal for the end of the drive shaft I6. The drive shaft I6 through suitable gearing 56 is adapted to drive a drum driving gear 5S. The drum drive gear 58 is suitably xed to one of the end hubs Si! of a character drum 62. The hubs 60 are rotatably mounted in bearings E4 supported in the side plates 52 and 54. Attached to the hub sections 60 of the character drums t2 are annular members 66 which support the character drum` 62. The drive gear which drives the drum is preferably proportioned so that the drum 62 will make one complete revolution during three machine cycles, that is to say, if three cards in succession pass the sensing brushes during the transit of these three cards, there will be one complete revolution of the drum 52. The drum is rendered opaque except at the character displaying portion thereof where the drum is transparent or translucent.

Disposed within the drum are a plurality of gaseous discharge tubes such as neon or mercury vapor tubes Bt. Normally these tubes are not energized. When it is desired to record, a source of potential. is momentarily applied to the gaseous discharge tube at the instant the desired character in the wall of the drum is in proper registration for recording. The light from the gaseous discharge tube will transilluminate the character, and such character will be recorded on a photographic fllm as will be subsequently ex-l plained. Since the drum hubs 60 are hollow, it is possible to provide supports extending from the outside of the drum through the hubs and into the interior of the drum to support the discharge tubes therein. A cable may be also led into the interior ofthe drum through one of the hollow hubs. Such cable aifords the leads to provide current to the individual discharge tubes.

' The terminal ends of the tubes lit into conductive socket elements which are molded in a block of insulating material lll, the block being supported by suitable brackets '12. Insulating separators I4 of opaque material are provided between the tubes to prevent illumination from a tube related to one character column to eifect other character columns. It will be understood that a single tube is provided for each column of characters on the drum. A mask 'It with a central slot "I8 is interposed between the drum and a camera unit of the recording section so that only a single line of characters will be photographed at one time.

Reference to Figs. 6 and 7 will illustrate the nature of the camera unit including the means for supporting film spools and for feeding lm past a lens. A.k camera housing is adapted to t into flanges 82 attached to one end of the section housing I2. The camera housing may be removably held in position by means of thumb nuts 84. A camera frame plate 3% has mounted therein three rotatable shafts 8B, tu and 92, the shafts having xed thereon film feed sprockets 94, 9S and 98, respectively. These sprockets are adapted to t a color sensitive lm strip Il) which is provided with the usual sprocket holes at the longitudinal marginal edges thereof. A

v'Tilm'take-up.spool |02 is provided for thelm.

this spool beinsmounted on a rotatable shaft |04.

`Film 'feed is effected from a lm spool |116 `,mounted for rotation cna -spool'shaft Vills upon energization and .successive deenergization of a 4film-feed solenoid ||0 (see Fig. 6). Energization vof the solenoid lowers a linkage system l 2 which -carries a feed pawl H4, the feed pawl ||4 being engaged with a ratchet wheel IB which is xed to a pinion H3. The ratchet wheel ||6 and the pinion I8 are rotatably mounted on a stud shaft |20. The pinion I |8 meshes with a gear |22 whichhasattached toit a smaller gear |24. The gear |24 in turn vmeshes with a gear |26 which is :fixed tothe` shaft'SG from which the sprocket 96 .isidriven Gearing |28 also transmits motion to v:,the'upper sprocket shaft `68. Gearing |30 also idrives Ythe lower .sprocket Vshaft 92. isprocket shaft 92 carries a pulley |32, which The lower Aratchetwheel |6t` lone step. `Each advancing step vof the ratchet wheel through the drive connections previously described drives tne various sprocket wheels and the take-up spool and advances the nlm one line space. A spring pressed .lever 1| 40 (Fig. 7) rests in contact with the nlm on the supply spool |96, .and when the film on .the supply spool is substantially exhausted, the lever |40 will swing to a position in which con tacts |42 `are permitted to open. In a manner which will be subsequentlyexplained, the opening of contacts |42 terminates the machine operation.

.As best seen inFig. 6 of the drawings, a housing platemember |44 providessupport for a lens .and shutter assemblyll. The shutter assembly .includes a shutter operating member |48. The shutter is adjusted fora so-called bulb ,exposure operation, the same being normally open during recording. Thefshutteris opened by moving the shutter operating member |48 upwardly, and the .shutter is `closed upon return of the operating member |48 to its .lower position ,as -viewed in Fig. :6. The member V|-48-abuts .the top of aslide |50 having a pin andslot ,connection with a lever |52. The lever |52 .ispivoted ,on a stud |54, and an Yextension of .the lever ,|52 .beyond its pivot point rests in contact with a .detent |i56. 'With the .partsin position as lshown inllig 6, the, lever 52 .isat its ccunterclockwise.limit of movement, and .the connecting slide |59 isin .its upper position in which itholds the shutteroperatingmem- .ber MBinshutteropening position. yIn the other position ofthe parts, `the lever |52 is .in clockwise displaced position, .and the operating slide 50 is in its lower position in which `it permits the shutter operatingelernent .i 4,8 to move the shutter to closed position. The detent |56 is springactuated and contacts with .the end of the lever `|52 to maintain the lever .in either of its two positions. Operation ofthe shutter accordingly may be effected by rotationof the lever |52 about its pivot.

Circuit diagram ABefore themachine Ais placed into operationto record a run of cards, certain plug connections must rst be made. Assuming that auto-control is desired on1several classiiicationcolurnns, plug Lnections aremadejfromisockets |6201 these same pick-up 'coils Vto the double sockets |64 which are wired tothe regular sensing brushes B-2 `for the classication columns. If two columns, for

example, are to 4be `used for auto-control, two

pick-up coils of relays PH are plugged up in this manner and plug connections also are made from a pair of the |65` sockets to the E68 sockets which are wired to contacts Pil-2 of the `two utilized PH relays. The number of connections between |65 and Hi8 will correspond to thexnumber of columns which are plugged up for autocontrol.

Other plug connections are made Afrom desired ones of the `sockets' |613 `of the B-2 brushes to sockets Ill) which connect to relay `coils E. It will be understood that one relay coil E is ,provided for each column of `recording, but for simplicity in the circuit diagram only three of such coils are shown. through coils E are the sensing circuits established through card periorations, and they control the recording of designated characters. The current supply for these sensing circuits is at relatively low line voltage. On the other hand, with the vpresent machine, the gaseous tubes by which the lm is exposed `are red with current at a relatively high voltage, and it is desirable that the high voltage circuits be isolated from the sensing circuits. Accordingly, the relay coils E are utilized, these being energized under line voltage applied through the card sensing circuits. These relays E in turn are utilized to conneet up the gaseous tubes to `receive high voltage current and to be'fired for recording as will be subsequently explained.

The .opposite `,terminals of each individual gaseous tube 68 are connected to plug sockets |s'l2 and VM. A plug connection is made from the 4|14 socket `of 'ga tube to a H6 socket and another .plugfconnectionis made from the |12 socket of the tube to `a -l'l socket. It will be understood .thatJ-asgmanyitubes are `utilized as are necessary ffor ,tlre required number of columns 4to be recorded. v.In practice lthere is one tube for each column of `characters -upon the drum and while only fa few tubes have `beenshown inthe circuit :diagram l:for -simplicitylof illustration, it will be -appreciated that any number may be provided. Qther plug vconnections are made from vplug sockets .to plug sockets 82. The latter plug connections are uin .thecharging .circuits of certain .condensers commonly designated K.

It may here bementioned that with the presentgmachine Vexposure of variabledata from the character ycarrying drum '.62 iseiTect-ed by flashing .the tubes at the proper diierential time. `Such tubesrequired considerable voltage to flash orzre them. In vorder Vto provide such voltage, according itothe present invention, use is .made of sets of `condensers K, `one iset of condensers being'provided for each tube in the system. In generalgitmay be stated that the condensers are charged-fromzthe relatively low voltage D. C. supply line with ithe condensers of each set con nected in parallel. Accordingly, each condenser ofthe -set will be charged to approximately the linepotential of the D. C.:supply line. After the condensers are thus charged and before recording, provision is madefor :reconnecting the -con- The circuits completedV many lines of improperly exposed 1ihn might be run through the machine before nal examination of a developed film would make it apparent that one or more tubes had failed to ire as intended. To prevent such undesired operation, testing and indicating means are provided. While this testing and indicating means will be subsequently described in greater detail, its general principle of operation may be mentioned here. If a particular tube fails to fire during a cycle, its related bank of firing condensers will retain a charge after the recording period of the cycle. This retained charge is utilized to energize a testing relay. If such a testing relay becomes energized, an indicating lamp pertaining to the particular column of undischarged condensers is illuminated and further the machine Voperation is automatically terminated. On the other hand, if a set of condensers after recording operations retains no charge, the testing relays will not be energized, the indicating lamp or lamps will not be illuminated and the machine operation will be permitted to continue.

Assuming the proper perforated records are in the supply magazine 36 (Fig. l), the operator of the machine i'lrst closes the main line supply switch |84 (Fig. 8) providing D. C. current supply to buses it and |88. The start key is now depressed, closing start key contacts |99 to complete the following circuit: from the line |86, through the serially connected D| contacts of the various detecting and testing relays D, through the master auto-control contacts G-I, through the start key contacts |9il, through the ilm lever contacts |512 and through the card feed clutch magnet 3@ to the other side of the line |88. A branch circuit is also completed through a holding relay H which on energization closes contacts H-I. Energization o the magnet 3|! starts card feeding in the -customary manner and the cards are advanced from the supply hopper. the first machine cycle a card reaches a position in which its leading edge is under the brushes B| in which position the card lever contacts 45a. are closed. Closure of these card lever contacts causes energization or" the relay coil M, closing contacts M2 to provide a holding circuit for the coil through cam contacts CF-L Coil M also closes contacts M-I. Contacts M-I the stop key contacts, and now closed contacts H-l, shunt the start key contacts |91@ so that the start key may now be released and the machine will continue in automatic operation until the card supply is exhausted or a change in card group occurs. During the second card cycle, the rst card is fed to a position in which it causes the second card lever contacts i3 to close. Accordingly, coil N is energized, closing contacts N-l which are in shunt with contacts M-I. Coil N also closes contacts N-Z to provide a holding circuit for the coil by way of cam contacts CF-Z. The holding circuits for the relay coils M and N are provided so as to maintain the coils energized during the intervals in which the card lever contacts open between successive cards.

During the third card cycle, the first card will In n b-e sensed by the B-2 brushes and the second card will be sensed by the B-I brushes. At the beginning of the third cycle, a charging circuit is established to the condensers K. With the card lever relay coil N energized, relay contacts N-3 are closed and a circuit is established from'the line |86, through N-3, through a commutator timer CD-l to a line |92, thence through a resistor in parallel through the normally closed switching contacts R-Z and the various K condensers of the set, thence out through the normally closed S-E switching contacts to a line leading to the plug sockets |86, thence via the plug connection to |82 to the line |88. Provision is made `for reconnecting the condensers from their parallel charging relation to a series discharging relation. Closure of cam contacts CF- at the time shown in the timing diagram establishes an energizing circuit for relays R and S. With the relays R and S energized, the contacts R-Z and. 5 2 open and the contacts R-l and S-I close. With the latter contacts closed, the several condensers K of each set are connected in series relation.

t may be here mentioned that there is a CD-I timing commutator for each of the sets of condensers and all of the sets which have been connected to the line |88 through plug connections between sockets |8 and |82 are concurrently charged.

During the third machine cycle, the leading card is sensed, the recording control magnets E are energized, and the auto-control circuits are set up. Assuming that the cards under the brushes have agreeing group designating perforations, the auto-control circuits are established as follows: from the line |86, through the lvl-3 relay contacts, cam contacts CF-S to common brush and contact roll 42. thence through the B-l brushes which sense the group perforations, thence through the plug connections between sockets |58 and i, through the pick-up coils p of the auto-control relays .PI-l, thence through the plug connections from |62 to IM, back through the B-2 Vbrushes to the contact roll 44, through CF-l cam contacts, through relay contacts N-' and back to the line |88. The auto-control magnets PH are of the usual dual winding type and the energized pick-up coils close the holding contacts PH| to energize the companion holding coils h through circuits extending from the line |86 and through the cam contacts CF-l. The energized PH magnets open the related PH-Z contacts so as to prevent energization of the masf ter auto-control relay coil G. It may be pointed out that if the cards do not have corresponding group perorations, then the PH-Z contacts will remain closed and upon closure of the cam contacts CF-S near the end of the cycle, the circuit of coil G will be established via relay contacts ril-5. Coil G will then open contacts G-I to break the card feed clutch magnet circuit.

The relay coils E are energized under the control of the B-Z brushes as they sense the character designating perforations in the card in columns where recording is desired. The circuits are from line |38, through the N-i contacts now closed, the CF-l contacts to contact roll M, thence through B-2 brushes, through the plug connections from |64 to lli), through the relay coils E and back to the line |86. It will be understood that the relays E' are energized at diierential times in accordance with the differential positions of the holes in the record cards. Relay coils E only energize momentarily but upon energzation, they close their related E'-| contacts; With such E| contacts closed, a tube hashing circuit or circuits are established as will now be described.

These circuits extend from the, right hand terminal of the lowest K condenser of a set, for example the left hand set in Fig. 8, through the condenser, thence through the. Wire which eX- tends to the econd S-i contacts from the bottorn of the now closed S| contacts, then through the nextY condenser and so on iny succession in series through the various condensersv and the S-l contacts, finally through the uppermost condenser, through the now closed' R-I contacts, through the plug connection between plug sockets |75, I'I, thence through the tube 68 or 68A, depending on the position of the CCM-2 contact, through the plug connections between sockets |12 and |18 via downwardly extendingfwire, through theV now closed l-I contacts, through a timing commutator CD-E, via wiresn |94, back through a resistor |96, through theL lowest S-l Contact and'back to the startingpoint. It will be understood from the foregoing that theY condensers discharge through the `related tube when the condensers are connected in series relation.

It may be here mentioned that the commutator CD-Z' istirned fora very'short duration of cir-V cuit: closure, which duration is` sufficient to re the tube and thereby effectively exposing thefilm by transilluminating the passing characterl of a characterY column on the drum.

It will be understoodL that while the circuit has been traced for one particular column of condensers and for one tube, exposures may occur for a multiplicity of columns.

The selected character on the drum passes the exposure position at the time the related tube is illuminated under control of the corresponding index point in the card, the commutator contacts CD-2.closing for a short period of time during which the particular index pointv is being sensed.` The drum characters selected bythe designations in the card. columns can thus beY ex.- posed and recorded at differential points ofthe cycle and such exposure for different columns mayoccur` either. concurrently or' at different times depending on whether like: or unlike designations are sensed in the card columns. Ex.' posure of characters` in different' columnsA during a card cycle will bel effected. on a common line on the film.

Feed of the film will. follow each exposure. Upon closure of cam contacts CIF-3 a circuit. is: completed from the line |88, through relay con.- tacts N-S now energized, through the CF-Za` con tacts and through lm feed solenoid (see Fig; 6). Energization' of the solenoid followed byits'` subsequent deenergization upon opening of cam contacts (3F-3 causes line spacing of the lm in the manner previously described.

Provision is now made for detecting. mis-operation of the tube or tubes. If a tube has failed to re there will be a charge remaining in the condenser bank associated with the particular tube which failed to nre. Before testing is effected, relays R and S are deenergized by opening of cam contacts CF-B. Accordingly, HP2 and S-Z contacts reassume the normal relation shown in the wiring diagram. Assuming a charge remaining in one or more of the condensers K, cur-- rent will ow from the charged condensers through the R-2 contacts now closed, to a line |98, thence through relay contacts N--'| now closedthrcugh cam contacts CIF-5, which close at the time shovvnin the timing diagram, through one of the detecting relay coils D, through a resistor Z, through the S-2 contacts to the opposite sides of the charged condenser. The current inthe circuit thus established' is sufcient to energize the D coil, closing related contacts D-2 to establish. a circuit throughkey contacts 292i', through an indicating lamp 2SA, through the D-Z contacts, through the D relay coil, through resistor 2te, through a plug connection from |80 to i3? and back to line |88. A lamp 2`|4is provided for each condenser column (see also Fig. 1). Failure of any plugged in lamp may be detected at once by noting whether its associated signal lamp 2M has been illuminated. The energize. tion of relay D also opens its related D-I contact and the opening of such D-l contact interrupts the holding circuit to the card feed clutch magnet 30, thus causing deenergization of the card feed clutch magnet and stopping further feed of cards through the card handling section of the machine. After there has been a tube failure, the operator detects which tube is faulty and re.- placesA it. Thereafter the warning' circuit through lamp 26d and related coil D is opened. Opening up of such circuit for relay D and the signal lamp 2M is afforded by manual operation of the key which controls normally closed key contacts 202.

With the present machine, when a change in control occurs between card groups, provision is made for effecting additional film feed to give distinct spacing between the successive groups. When successive cards with disagreeing. group control perforations traverse brushes B-I and B-Z, one or more of the auto-control magnets PH are not energized and the related PH-2 contacts remain closed, and when the CF-S contacts close, coil G is energized as explained before, through the closed PPI-2 contacts and the N-5 contacts. Coil G closes holding contacts G.-2 providing a holding circuit for the coil, through cam contacts C|. Energization of coil G also opens contacts G-| to break the card feed clutch magnet circuit, causing interruption in card feed. Coil G also closes` contacts G-B, establishing a circuit from line ISB, through these contacts, through cam contacts C-2 when closed, then through the nlm feed magnet l I0 to the line |86. Upon opening of the cam contacts C-2, the cir-- cuit just traced is broken and the magnet lli) deenergized. As a result the lm is line-spaced. Coil G is still energized and contacts G-3 still closed when cam contacts C-3 close. Contacts C-3 function to the same effect as contacts 0 2. Hence a second energization and deenergization of magnet In occurs, causing a second linespac.-

ing of the lm. Following this additional line spacing operation, provision is made for automatically reinitiating card feed. Reinitiation of card feed is erected as follows: With relay contacts G-4 now closed, the clos-ure of cam contacts C-4 completes a circuit from line |8, through G-4, and C-4, to the card feed clutch magnet 3B and coil H. Card feed of records pertaining to a followingA group will now automatically be resurned.

C0101- screen operation As hereinabove indicated the present invention is designed for the photographic recording of data in selected color, and several forms of mechanism for such color recording have been disclosed herein. In the description to. follow immediately hereinbelow, oneform of the invention which involves the use of shiftable color screens will be described, and for the purpose of this description reference may be had to Figs. 2 through 5, inclusive. In these iigures the character drum62 hereinabove mentioned is the principal nlm exposing medium. Disposed immediately in front of the drum 52 are a series of strips 206 which are preferably formed of thin metal, and which are so arranged that a strip is directly in alignment with a character column on the drum. The strips 223 are provided with two cutout portions 29B and 210. The cut-out portion 211) has attached thereto a translucent color screen 212. The color screen 2i2 may be secured to the strip 235 by means of an adhesive cement. The cut-out portion 238 ordinarily has no color lter overlying the same since it constitutes the aperture used during normal recording operations.

The strips 252 pass through 'two sets of horizontal guides 212 and 213, and a further set of restoring guides 2 i 3, which cooperate with a projecting stud 222 carried by each strip for the purpose of restoring the color screen strips as will appear more fully hereinafter. Springs 222 and 224 are secured to the upperand lower extremities respectively of the strips 222. The opu posite end of the spring 222 is secured to an upper cross bar 223, and the opposite end of the spring 222 is secured to a lower cross bar 222.

The spring 221i is stronger than the spring,r 222 and serves to pull the strip downwardly upon release of the strip so that the color screen 212 is in registration with a character of the drum 32 which is in recording position. The spring 222 is merely strong enough to hold the strip 2li?) in upright position and to provide a ilegible connection between the upper end of the strip and the supporting cross bar 223.

Normally the strips 222 are in the position shown in Figs. 2 and 4 of the drawings, and they are held in this position by the latching action between a projection 232 formed in the face of the strip and an electromagnetically operated latch 232. With the strip in the position shown, the cut-out portion 228 is aligned with exposure slot '18 in a light mask '1311. Accordingly, when a ilash tube such as the tube S3 is illuminated forrecording purposes, the recording on the nlm, in this case color film, will be a bluish white if the lamp t8 is a mercury vapor lamp, or the recording will be red if the lamp is a neon tube. For the purpose of illustration, let it be assumed that the lamps 63 are of the mercury vapor type. The latches 232 are individual for each strip 203, and each latch is controlled by a related electromognet 234. The latches are provided with pull rods 233 which connect them with their magnets. When it is desired to change from the bluish white recording to the red recording in any particular column or columns, the corresponding magnet or magnets 232 are energized, thereby shifting their associate latches 232 out of engagement with the related strip projections 233. This will permit the spring 223 to move a released strip 236 downwardly until its stop studs 223 engage the restoring guide 218. Color filter 212 will then be in alignment with the exposure slot '18. When the related tube E32 is iiashed, the recording will be in red rather than in the bluish White color in which the recording appears when the exposure is through the cut-out 238.

The driving action of the restoring guides 213 may now be described with reference to Figs. 2 and 3 of the drawings. A cam 238 is secured to the gear 56 which engages the drive gear 58 for the character drum. A follower link 240 constitutes a connection between the cam 233 and a sliding cross-head 242 which slides on vertical bars 22d. A similar structure is provided at both sides of the machine so that the restoring guide 218 has imparted thereto an even movement. A shaft 226 extends through the side plates of the unit to provide a drive for the opposite restoring cam. A slot 245 is cut in each side of the frame to permit connection between the cross-heads 222 and the restoring guides 218, as well as for the purpose of providing for the vertical reciprocation of the latter. The contour of the cams 233 is such that they start their upward movement at approximately l1 in the cycle and return to rest position as shown in Fig. 3 of the drawings shortly before 9 in the cycle.

The circuit controlling the normal recording of data has been described hereinbefore, and it is therefore appropriate at this point to further describe that part of the control system which governs the position of the color strips 236. The circuit connections necessary to effect control of the magnets 232 therefore follows. Reference to Fig. 9 of the drawing will disclose the additional control circuitsV that must be imposed on the general control circuit shown in Fig. 8 of the drawing for the control of the hereunto described color recording system.

Control for the color control magnets 234 will be under the iniiuence of a hole in the record card being analyzed, for example, a hole in the X position, such as the car-d in G. F. Daley et al. Patent No. 1,954,041. One hole in the position of a column may control the color of the recording in that column only, or an X position hole may control the color control magnets 234 in a plurality of columns. Assume, for example, that an X hole is sensed in the 15th column of the record card. Referring to Figs. 8 and L9, a plug hub 238 is connected by a plug wire to the upper brush plug hub 158 of Fig. 8 for the l5 column. This connection is indicated by the dotted line in Fig. 9 of the drawings. Assuming that it is desired to re-cord the rst three numbers on the left in red every time a perforated card appears, a plug connection is made from the plug hub 253 to the plug hub 252-1, and from the plug hub 252-1 to plug hub 252-2, `and finally from the plug hub 252-2 to the plug hub 252-3. The suiix 1, 2 and 3 attached to the plug hub numeral 252 indicates the first, second and third column from the left of the recording. In this example the first, second and third columns might contain a customers balance, and the punched record cards may represent debit cards against that customers account. In the event it is desired to record in red color in only one column, the plug connection would obviously be made only from plug hub 251i to the plug hub 252 for the single column in which the red color recording under X control is desired. In the event that it is desired to record different columns in red for one card than the columns it is desired to record in red for another card,. more than one X control will be plugged up in a manner similar to that just described.

With the plugging as described, whereby the control circuit of Fig. 8 is modified by the imposition of lthe additional controls of Fig. 9 and with cards disposed in the hopper 36, the main switch |84 may be closed and the start key may be depressed, thereby setting the card handling and sensing unit it into operation, and as a consequence the recording unit l2 which is under its control. When a card bearing an X perforation is sensed, a circuit is completed from the line |86, through relay contacts M-3, through cam contacts CF-S, through the common brush and contact roll 42, through the hole in a card being sensed, and through the reading brush B-i to the exit plug hub |58. The circuit further extends from the plug hub |58 to the plug hub 248 (Fig. 9) to energize the Y pick-up magnet, and from thence to the other side of the line |88. Relay Y, when energized, closes-its contacts Y-I, which maintain the relay energized by a circuit through CF-4, to the other side of the line. Shortly thereafter relay contacts CF-iO close to complete a circuit from the line |86, through contacts CF-IU, through relay contactsY-2, through relay Z, and to the other side of the line |88. The relay Z is maintained energized into the following cycle for controlling purposes through its contacts Z-|, and cam contacts CF-l At the start of the cycle in which color control is desired, a` circuit isconf pleted from the line |66, through the cam vcontact CF-|2, through relay contacts Z-Z, now closed, plug hub 258 and to one or more of the plug sockets 252, and consequently to one or more of the color strip control magnets 234, and thence to the other side of the line |88.

Energization of a magnet 234 will trip the latch 232 as previously described, thereby permitting the color screen 2|2 to drop into alignment with the exposure slot 18. Accordingly, when the tube 68 is flashed, the recording will be effected in a different color than would occur during regular operations of the machine when the color screen 2|2 is not moved into alignment with the eX- posure slot.

Near the end of the cycle the color screen strips 266 which have been released and lowered under the influence of their respective springs 224 will be restored to their upper latched position under the action of the restoring guides 2 I8. The manner in which recording of more than one color may be effected under X control with a colored mask or color filter has just been described.

Multiple character drum operation The foregoing manner of selectively reproducing data in color on photographic lm is one Way of achieving the general' objective of the present invention, but in order to indicate the scope ofthe invention herein a further method for accomplishing the purpose under perforated card control will be described specifically, and this description Will proceed mainly with reference to Figs. 6 and 7 of the drawing, insofar as mechanical aspects are concerned and With reference to Figs. 8 and 10 ofthe drawings, insofar as automatic control of the` mechanism may be concerned.

In accordance with the modified recording structure there are provided two character drums and two sets of gaseous discharge tubes, the tubes being so selected that the illumination from the tube itselfA results in a color of the desired character. Circuit controls toV permit the flashing of tubes in one or the other of a pair of drums being equipped with tubes of different illuminating characteristics vare provided, and an optical system which permits recording from two drums to a common film is part of the structure as shown in Fig. 7. In addition to the character drum 62, there is provided in the modified form of theV invention a second identical characterV drum 254. Each drum is provided with al drum driving. gear; and particularly the drum 254 has associated therewith a driving gear 256. In order t0 impart motion to the drum 254, a set of idler gears 258 interconnect the gear 256 with the gear 58. which drives the drum 62. 58 to the gear 2.56, and accordingly the drum 254 Will rotate synchnonously'withv the drumV 62 and in the same direction.

The path of light. when a tube in a drum is ashedmay best be traced with reference to` Fig. '7 of the drawing. Thelight from the drum1254 will impinge onv a mirror 260`and Will be reiflected to a semi-reflecting and transmitting. prism 262 of the type shown and described in the U. S. Patent No.V 2,371,120 to R. T. Blakely; The light is then reflected tothe lens |46 of the camera assembly'and a character image will be recorded on the film. Light from the drum 62 will impinge. on a mirror 264, and it will be reflectedto a mirror 266.which inturn passes..

thezlight, through the prism 262 and through the camera'. lens |48` to theA lm. Thegaseous tubes 68A in the drum 254 may contain mercury vapor and the gaseousV tubes 68 ofthe drum `62, in this instance, may contain neon. It has,

heretofore been explainedv that the lm exposed to the rays of a mercury vapor. lamp will pro:- duce a bluish white image,. whereas the same film exposed to the rays of. a neon lamp will result in a red recording.. Consequently, therev is no necessity inthe modified form of the mechanism for the interpositon of color screens, inasmuch as the light sources themselves determine the color in which the character will be recorded on the film.

The circuit connections for controlling the modified form of the. invention will be understood by reference to the general control diagram 'of Fig. 8`When viewed in connection with the specific control diagram of. Fig. 10 which is imposed on the general control system for the selective illumination. of lamps in either; character drums 62 or 254; The tubes 68 and 68A are connected as shown and as will be explained; the selection of oner of thesev is effected by relay contacts CCM-2 (Fig. 8).

For control of the lamps under the influence of an X hole of a record card, it will be necessary that a plug hub 268 (Fig. 10) be connected by a plug Wire to the upper brush plug hub |58 of Fig. 8, thisA connection being made, for example, at the 15th column position. The plug wirel is shown in dotted lines in Fig. 10. Assuming that it is desired to record the first three v numbers on the left in red every time an X perforated card appears, a plugv connection is made from the plug hub 210,. to the plug hub 212-I, and from theY plug hub 212-l to the plug hub 212-2, and from the plug hub 212-2 to the plug hub 212-3, the suiix 1, 2 and 3 used in con-V nection with the plug hub numeral 212 indicating the first, second and third column from the left of the recording. In this example the rst, second and third columns again might contain a customersY balance, and the X punched cards mayv represent debit records flor charge against the customers account. In the event it is desired to record in red color in only one' Idler gears 258 provides drive from thegear thecolumns' it is desired to record in red for another card, more than one X control Will be plugged up in a manner similar to that just described. The plug connections from sockets |12 to |18 and from |14 to |16 are as previously described. With the card hopper 36 supplied with cards and the machine set in operation by closure of the line switch |84 and depression of the start key |90, cards Will be fed through the card handling and sensing unit I as hereinbefore described. When a card bearing an X perforation is sensed, a circuit is completed from the line |86, through relay contacts M-3, through cam contact CF-9, through the common brush and contact roll 42, through the hole in the card, through the sensing brush B-l, and to the plug hub |58. The circuit further extends from the plug hub |58 to the plug hub 268 (Fig. l0) to energize the pick-up magnet 214, and to the other side yof the line |88. Relay 214, when energized, closes its contacts 214A which maintain the relay energized by a circuit through CF-ll to the other side of the line. Shortly thereafter cam contacts CF-l-A close to complete a circuit from the left side of the line |86, through the cam contact CF-Ill-A, through the relay contacts 214B, through the plug hub 216, the plug wire to the plug hub 212-|, through the relay CCM, and to the right side of the line |818. The relays CCM for columns 2 and 3 Will also be energized at this time because of the plug connections from 212-| to 212-2, and from 212-2 to 212-3. The relays CCM are maintained energized into the next cycle for controlling purposes through contacts CCM-l and cam contacts CF-II-A.

Accordingly, during the cycle that color control is desired, relay contacts CCM-2 Will be shifted so that the gaseous discharge tube 68 containing neon gas Will be connected in circuit for illumination during this cycle, rather than the gaseous discharge tube 68A Which contains mercury, and the recording will be in red rather than in bluish white.

As an'alternative to having tubes with differentA gases, similar tubes such as those containing mercury or neon may be used in both of the characterr drums 62 and 254i, but in this instance one drum would have merely cut out characters at the character columns thereon, whereas the other drum would have its characters covered by aV It has been previously mentioned in connec` tion with the objects of the invention that a preset color control may be effected for both embodiments of the invention. Considering now the first described embodiment of the invention, and assuming that it is desired as previously described to record in red color in the three left hand columns of the record film, the plug connections from plug hubs |58 to plug hubs 248, and from plug hubs 256 to plug hubs Z-l, etc. are not made. IOn the other hand, a plug connection is made from a plug hub |58A to plug hub 252-I, and from plug hub 252-l to a plug hub 252-2, and from plug hub 252-2 to plug hub 252-3. Then the color control magnets 236 of the selected columns will be energized every cycle by a circuit from line |86 through cam contact C11-I2, through plug hub |68, and by way of plug connections to the plug hub 252-I, thence to plug i6 hub 252-2 and to plug hub 252-3, to the magnets- 23e and to the other side of the line |88. If only a single column of red recording is desired, it is obvious that only one of the plug hubs 252-l etc. will be plugged to a |58A plug hub.

In connection with the modified form of the invention, if it is desired to preset color control, the connection from the plug hub |58 to the plug hub 268 is eliminated, and instead of plugging from the plug hub 210 to the plug hub 212-|, a connection is made from plug hubs 216 to selected ones of the plug hubs 212-I, etc., thereby effecting an energization of the selected CCM magnets at every cycle to control the color in the particular column or columns so selected.

As the last cards pass through the sensing section, irrespective of the type of control employed, there is, in eifect a break in auto-control, causing stoppage in machine operation. This break in control is due to the fact that relay contacts M-3 are now open and no circuit is provided to the contact roll d2.
