SHEET-POSITIONING MECHANISM.

To all whom it may concern:

Be it known that I, JOSEPH WHITE, a citizen of the United States, residing at Piscataway township, county of Middlesex, State of New Jersey, have invented certain new and useful Improvements in Sheet-Positioning Mechanism; and I dodebe a'full, true, and exact description of the said invention, such as will enable others skilled in the art to which it appertains to make use of the same.

This invention. relates to mechanism for positioning individual sheets before they are presented to machines for operating on such sheets and particularly to devices for s0 presenting the sheets to the feeding or impression cylinders of printing machines that each of them will be taken by the sheet taking mechanism of the cylinder so that each sheet will have the same relation to such cylinder as all other sheets. My new mechanism is particularly useful in positioning sheets of heavy or stifi' material, such as tin or cardboard, though it is by no means limited to such material. My novel mechanism may be used in connection with any form of sheet handling devices, such as sheet separating devices by which sheets of material are taken up from a pile and presented 'one by one to the machines, machines in which sheets are cut from a web, or with hand-fed machines. In any form of mechanism for presenting sheets to a machine, it is desirable that the sheet shall be positioned longitudinally and laterally bethe mechanism to do this should be simple in construction and certain in operation, and preferably the gages for so positioning the sheets-shouldbe adjustable for. various.

sized sheets, and it is desirable to provide a mechanism for'automati'cally positioning the sheet without any -care on the part of the feeder.

My novel mechanism to'accomplish these objects consists of Y a simple and .effi'cient construction and arrangement of parts as will be more fully described and pointed out in the appended claims.

Fig. 5 is an elevation of Fig. 4:.

The corresponding parts are referred to both in the drawings and the following description by similar reference characters.

Referring now particularly to Fig. 1, 10 is an impression cylinder cooperating with a form or other printing cylinder 11, these cylinders in the type of press which I have chosen for purpose of illustration, being geared together and driven by power. Since such driving means are no part of my invention, they are not illustrated. 12 is the usual gripper shaft carrying the usual rying a cam roll 15, which as the cylinder 10 rotates, engages with the cam 16 to open and close-the grippers in the usual manner. After the grippers are closed, they are held in this position-by the usual spring mechanism. Instead of the grippers which I have shown, any other equivalent sheet taking device, such aspins, may be employed.

17 and 18'318 shafts rotatably mounted in the frames of the press, the .shaft 17 being provided with gear .19 which meshes with an intermediate gear 20, which in turn, meshes with a gear 21 attached to the shaft of theimpression cylinder 10. 22 represents a series of endless bands connecting pulleys 23 and 24 mounted respectively on shafts 17 and 18. These belts or bands may be of any material, such as leather, tape or strings. 'The proportion of the gear 19 to the pulleys 23 is preferably such that the bands 22 move at a greater speed than the surface speed of the impression surface of the cylinder 10. The shaft 18 may be positioned any distance away from the shaft 17 as will be found most convenient for feeding sheets to the belts. The sheets of material S to be fed to the cylinder 10 are placed on the bands 22 either by hand or by automatic mechanism and the bands 22 are driven in the proper direction to carry such a sheet toward the cylinder 10.

40 is a fixed rod extending between the side frames of the machine and carrying thereon sheet guides 41 the top portions of which serve to support the sheet between stantially the same speed as the surface speed of the impression cylinder 10, and in such a direction that the lower portion of such chains move toward the cylinder 10.

As shown more in detail in Figs. 2 and 3, the chains 29 have brackets 31 attached thereto on which is mounted a shaft, 32 carrying block 33 held adjustably-on shaft 32 by a set screw 34 and the spline 35. The

block 33 is provided with a front gage 36 having a dependent portion 37 and the gage 36 is'slidingly mounted on the block33 and adjusted by the screw 37 and locked in place on block 33 by the screw 38. 39 is a spring adapted to direct a sheet a'ga'instthedependent portion37 of the front gage. It will be understood that as many of the front gages 36 as are necessary will be provided on the shaft 32, though two is the preferable number.

As shown particularly in Fig. 1, it will be seen that the front gage 36 moves for a portionof its length toward the cylinder above the bands 22 and parallel therewith, and with its dependent portion 37 in the path of a sheet on the bands 22. In the structure illustrated in the drawings, a sheet placed on the bands 22 will be moved by such bands toward the cylinder 10 at a greater velocity than the velocity of the front gage 36. If such sheet does not have its front edge parallel to the front edge of the impression surface when placed on the bands 22, it will be thrust into such a position by being pressed against the front gages 36,before the edge of the sheet arrives at the point where it will be taken by the grippers of the cylinder 10, the front gages, when two or more. are employed, in connection with the bands 22 acting, therefore, to straighten the sheet. Preferably, I arrange the sprocket chains 29 in such a way that the front gages cut across the path of the impression surface of the cylinder 10. With this arrangement the sheet may be directed tangently to such after passing over sprocket wheels- 28,

again conie into the path of the bands 22 ready to receive another sheet.

In the mechanism just described, it will be noted that the front gages move with the sheet up to the point where the grippers close on the sheet and that they then continue to move in .the same direction while beinglifted out of "the path of s'the sheet. The grippers, of'cpurse, close at each revolution of the cylinder at the time when the front edge of the sheet is at a certain predetermined point and preferably Iarrange my gage carriers so that the front gages do not alter their relation to the sheet until at about the time the edge of the sheet has arrived at this point and the grippers are closed. The grippers are therefore actually controlling the sheet before the gages are removed. This is possible in the structure I have illustrated because the further motion of the gages is principally with the sheet and not across or against its path, the gages passing from one side to the other or through, and not simply up to, the plane determined by the center line of the cylin;

der-and the position of the edge of the sheet at the time the grippers close.

In order to position the sheet laterally, I provide a bar 42 whose ends are carried in the sprocket chains 29 in a manner similar to that in which the bar 32 is carried. On this bar 42 are mounted blocks 4344 which are adjustable lengthwise of the bar 42 and held in adjusted position by the set screws 45. In the block 43, is slidingly mounted a rod 46 having a head 47 and a' spring 48, the latter abutting against the block 43, and a collar 49 fastened to the rod 46. Similarly, block 44 has a rod 50 mounted slidingly therein and carrying a head'51,

the-rod 50 being provided with a spring 52 abutting against the block 44. and the collar 53 fastened to the rod 50. To the block 43 is pivoted a cam lever 54 carrying a cam roller 55. A link 56 connects the lever 54 with the block 47. Similarly to block 44 is pivoted a cam lever 57 carrying a cam roller 58. The block 51 has a projection 59 through which passes one end of a link 60 connected at one end to the lever 57. On this link 60 between the lever 57 and the proj'ection59 is a spring 61. From each of the blocks 47 and 51, respectively, hang down gages 62 and 63, having projections 64-65 on the ends thereof and springs 66 to direct a sheet into the gap formed between the projections 64-65 and the cutaway portions of the side gages 62-63, as shown particularly in Fig. 5. These projections 64-65 extend under the sheet S being positioned and thus support it, which I have found desirable to ob-. tain accurate registration. The gages 62-63 are mounted in the blocks .47-51 so as to be movable longitudinally therein, being normally heldin the positions shown, by the springs 66. When the device is used in connection with a cylinder having a sheet bearing surface, as illustrated, this arrangement permits the gages 62-63 to be pushed up into the blocks 47-51 when they contact with such surface without injury to either the surface or the gages. 67-68 are fixed cams mounted on either end of the'rods 69-70 carried in the'frames of the machine, such cams being adjustable toward and away from the center of the machine, and held in' adjusted position by the set screws7 1. I

The springs 48 and 52 are arranged to hold the cam rollers 55 and 58 against the cams 67 and 68, respectively, as the-jbar 42 is carried along by the chains 29 toward the cylinder 10. The cams 67-68 are so designed that, as the bar 42 passes around the sprocket wheel 28 the blocks 47-51 are normally drawn back against the blocks 43-44 by the springs 48 and 52. As the side gages 62-63 pass around the sprocket wheel 28 they come into the plane of a sheet carried on the bands 22, and at the proper time in their travel, as determined by the shape of the cams 67-68, they are moved inward to engage the sheet S. The block 47 and the gage 62 are moved in positively, while the block 51 and the gage 63 are moved in yieldingly by reason of the spring connections 61. The'gage 62 serves, therefore, to press the sheet up against the gage 63 and then the spring 61 yields. It will be understood, of course, that this action takes place while the sheet is being progressed toward the cylinder 10 by the bands 22, and is being held against the front gages 36 so that the side gages are working on a sheet WlllCh is practically stationary relative to the side gages. As soon as the sheet is taken by the grippers 13, the rollers 55-58 reach the portion of the cams 67-68 indicated by 72-73 and the side gages 62 and 63 are moved back by the springs 48-52. It should be understood that the spring 52 is stronger than the spring 61. This action of the gages serves to carry cated so as to position a sheet of any size in proper relation to the cylinder.

After one sheet has been positioned laterally and taken by the grippers 13, the bar 42 with its gages moves with the chains 29 around the sprockets 27 and the sprockets 28, when the rollers 55-58 again engage the cams 67-68 to open the gages 62 and the gages are held in this position as they move into the plane of the sheet on the bands 22, before being closed by the cams 67-68 as the gages move toward the cylinder.

In my preferred form, the operation of my sheet positioning device is as follows: A sheet is placed on the bands 22 which are moving at a greater velocity than the chain 29 or the surface of the cylinder 10, and is carried by the friction of such bands against the front gages 36 which are moving parallel to the sheet and at substantially the same speed as the surface of the impression cylinder. This causes the sheet to be straightened and the front edge of the sheet to have its proper longitudinal relation to the front gages 36 and therefore to the surface of'the cylinder 10, since the front gages and the surface have a fixed timed relation by reason of the gearing 21-27. While the sheet is being moved forward, the side gages 62-63 are being closed in by the cams 67-68 until they contact with the sheet. After an edge of the sheet is in contact with each of the side gages 62-63, the sheet is properly positioned laterally and it is not crushed or bent by reason of the yielding of the spring 61. It will be remembered that the sheet during this side positioning operation is being carried toward the impression cylinder 10, which is constantly rotating, and at the proper time and while the sheets are held against the front and side gages, the grippers 13 close thereon.

Since the front and side gages are carried on mechanism pos tively geared to the cylinder 10,"it will be seen that each sheet will be positioned properly in relation to the cylinder.

The cylinder 10, as illustrated in the drawings, is of the continuously rotating type and my sheet positioning mechanism is espe-' cially adapted for positioning sheets on such "a cylinder, but my device may also be used with cylinders which stop to take a sheet. It is also obvious that it-is wholly immaterial Whether the cylinder 10 as an impression cylinder cooperates with a rotary form cylinder or a flat bed or a transfer cylinder, and it is also obvious that the cylinder 10 may be merely a feed cylinder or any other device by which sheets are conveyed to a machine.

'While preferably I move the chain 29 at I substantially the same surface speed as that front gages, it is obvious that the front gages may travel faster or slower than the impression surface, provided they arrive at the sheet feeding and the sheet gripping point at the instant that the grippers close on the sheet. -Moving the front gage and the impression surface at the same speed has several advantages, however, since the sheet is taken by the grippers while it is traveling at exactly the same speed as the impression surface, and While the sheet is still being held against the front gages.

While I have shown as my preferred form of carrier for my front gages and side gages the endless traveling carrier 29,

.it is obvious that many of the same objects may be accomplished by mounting these gages on any form of carrier, as, for in stance, a reciprocating one, which will move them toward the cylinder while they are positioning the sheet.

It will be understood that the gages are in reality the front surfaces of the members against which the sheet bears and not the whole member itself with all of its adjust. ing and supporting devices. Theoretically, the gage could be a surface only but practically it must have some thickness to support it. It will be understood, however, that when, in this specificationand the following claims I describe the gages as having a certain motion or position, I am referring to the effective part of the gage, which is the surface which. contacts with the sheets.

While preferably I use my sheet positioning device in connection with an automatic sheet presenting device, such as the belts 22,

.many features of my device may be used if the sheet is presented to the feeding point of the cylinder entirely by hand.

It is also possible for certain purposes to use either my novel front gages or my novel side gages alone and not necessarily in combination as I-have shown for purposes of illustration, although I prefer to' so use them.

While I have shown and described my new side gages as "consisting of a gage on either side of the street, which gagesare moved toward the sheet and toward each other as the gages themselves progress toward the cylinder, I do not wish to be limited to this particular form. It is posthan that of such sheet,'and means,

sible, for instance, to fix one of the side gages, allowing the sheet to be adjusted laterally entirely by one gage. This might be readily accomplished by moving the cam 67 away from engagement with the roller 54, so that the block 47 with its gage 62 remains pressed back against ,block 43 by the spring 48. This then becomes a fixed gage against which the sheet will be pressed by the gage on the block'5l. In such a case, if the gages are mounted on a chain as 29, it will benecessary to move the projection 64 from beneath the sheet S before the projection passes around the sprocket 27, or the projection 64 may be dispensed with altogether, which might readily be done, since this projection is not a necessary part of my invention. It is also possible to position the sheet laterally by causing one of my traveling side gages to push the sheet against a fixed side gage instead'of a traveling one. I Y

My device for straightening and positioning a sheet laterally and longitudinally may be used with a support which does not bring the sheet directly to the machine, but which delivers it in a straightened and adjusted position to another conveyer which does move it to the machine. In other words, it is possibletonse so much of my device as is illustrated by the bands 22 and the carrier 29 nd the gages supported thereby at any stage of the travel of a sheet toward a machine which is to operate on the sheet. It is also obvious that any other form of sheet conveyer, such as a reciprocating carriage, may be used inplace of my traveling. bands 22.
