MULTIFORM PRINTING PRESS.

Application filed July 28,

zen of the United States of America, and a resident of Hoboken, county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Multiform Printing Presses, of which the following is a specification.

My invention relates to improvements in printing presses, and in particular comprises features whereby a pressis produced which is particularly adapted for numbering sheets of bank cheques as Well as for printing on such sheets the name of the drawer of the cheque or other similar matter.

Sheets of bank cheques commonly each comprise three cheque blanks, together with corresponding stubs. Each bank commonly maintains a considerable stock of such blanks, printed according to its particular design, but lacking serial numbers and the name of any particular customer. .Many of the bank customers commonly desire special cheque books, the cheque blanks of which are numbered serially and also bear the customers name. To meet an order for such a special cheque book, an appropriate number of cheque sheets, each already printed according to the particular design of that bank, must be passed through a machine which will number serially each cheque blank andits corresponding stub, and will also print the customers name on the blank; after which the sheets are bound into a book. This is commonly done by a printing house which, commonly, carries a largestock of cheque sheets for each of a large number of banks. .It is necessary that the serial numbering, and the printing of the customers name, for any particular order, shall be done in a machine which can be changed quickly to adapt it to different orders, for each order, commonly, is for a relatively small number of sheets. The matter is complicated further by the fact that cheque forms of different banks vary greatly, particularly as to the location of the serial number. In some cheque forms, the serial number must be placed in the upper left-hand corner; in others, in the lower left-hand corner; and in still others, 1n the upper righthand corner. Also, some bank customers desire that their names be printed across the left-hand end of the cheque; others desire Specification of Letters Patent.

that it be printed inthe signature space; and still others, that it be prlnted in both said places. Furthermore, 111 many cases it is deslred that the serial numbering be done with ink of acolor different from that with wh ch the customers name is printed. These various complicating conditions have caused the use of separate presses .for printin the customers name on the cheques an for printmg the serial numbers, and have caused the use, for printing the customers name, of a cheque-printing press in which one cheque only, together with its corresponding stub, 1s printed at any one operation, the chequesheet being fed forward and positioned for the printlng, separately, of the several cheque blanks of the sheet, by handan operation requiring much Skill on the part of the operator,-who, nevertheless, occasionally Spoils a sheet. Furthermore, in the printing of the serial numbers the cheque sheet is positioned by hand, and is moved by hand from oneprintlng position to another, and it not infrequently happens that the sheet is badly positioned. I

My invention comprises means whereby the cheque sheets may be introduced without special care on the part of the operator, and thereafter will be fed forward automatically, from one printing position to the next, without special attention, or, in fact, any attention whatever on the part'of the operator; and whereby the printing of the customers name and the serial numbering of the cheques and their stubs, may be done in the same machine and at the same time, and may be done in any of the several required positions, as previously stated, and,,in most cases, in different colors if so desired. Other features of my invention will be described hereafter and set forth in the appended claims. The printing presshereinafter described as one embodiment of my invention is of course adapted for various other uses than the printing of cheque sheets; for example, is adapted for the printing of railway tickets and other tickets and forms of various kinds, and therefore my invention is not restricted to cheque presses only, but extends to'all classes of machinery to which it is adaptable.

The object of my invention is to improve the construction of cheque-printing presses and the like, to adapt the same for the automatic feeding-forward of the cheque sheets and the positioning thereof in the several desired printing positions; and, in general,

to produce a press which, while particularly a portion of the chase-carrying member being broken away; Figure 2 shows a side, elevation of the machine; Figures 2, 2 and 2 are similar side elevations of stop-fingeractuating cams employed in the machine; Figure 3 is a vertical longitudinal section of the machine; Figures 3 3 and 3 are similar fragmentary detail side elevations of various stop-fingers employed in the ma' chine; Figure 4 is a fragmentary horizontal section of a portion of the machine; Figure 5 is a vertical transverse section'of the machine; Figure 6 is a detail side view of cam mechanism for reciprocating the printing head; Figure 7 is a detail top view of the lateral positioning device; Figures 8 and 9 are similar detail transverse sections showing the lateral positioning device in two different positions; Figure 10 is a fragmentary perspective view of the lateral positioning device; and Figure 11 is an isometrlc perspective of the upper portion of the machine, certain parts being broken away.

In the drawings, 1 designates a suitable. frame for the machine. As shown, the construction of this frame is such that it may be built most readily of timber; but it will be understood that the particular construction of the frame, and the particular material of which that frame iscomposed, is imma-' terial; and, in fact, a metal frame will commonly be used. 2 designates a. feeding table,

designed to support a pile of cheque sheets, from which pile the sheets will be fed, one by one, and usually by hand, into the feed ing mechanism of the machine; and 3 designates a delivery table upon which the printed sheets will be deposited by the machine.

t designates a main driving shaft, and 5 a driving-belt pulley thereon, which pulley may be considered as representing, diagrammatically, any desired source of power. 6, 6, designate a series of a er-feed tapes, pasm'ng over main rollers f f, and 8, 8, of which rollers 7 are driving rollers, driven from shaft 4 as hereinafter described. 9 designates the bed of the press, around which, and its supporting frame member 1, the tapes 6 are carried by guide-rollers 10. 11 designates a cross-head, adapted to carry a type-form or type-chase, and adapted to be reciprocated up and down by suitable cam mechanism, as .hereinafter described. This cross-head is pivoted on a transverse bar 12, so that it can be thrown up and back (as indicated 'in dotted lines in Figure 3) for the convenient change of the typeca-rried by it, and normally rests, at its ends, on ledges of side plates 13, themselves mounted on rods 14, which slide up and down in bearings in the frame of the machine, being cross-c'onnected by a reciprocating frame 15 driven by a cam 16 on shaft 17. This frame 15 has two follower rollers 18 and 19, of which 18 (the upper roller) is narrow, and engages only the outer por tion of the edge of the cam, while the other roller, 19, is broader, and engages the whole face of the cam, except when a drop 16 is opposite that roller 19, when that roller engages only the higher part of the cam. When this drop 16 is opposite roller 18, the latter engages the drop only, and therefore at this time the printing head 11 is practically stationary. It is at this time that the hereinafter-mentioned inking roller passes across the face of the type carried by the printing head. Beneath the lower end of frame 15 there is a counterweight lever 20, pressing up against frame 15, and so reducing the work to be done by cam 16 in lifting other reciprocating parts attached thereto.

Upon certain of the feed tapes 6 rest light rollers 21. As a sheet to be printed is pushed forward from table 2 its edge passes between rollers 21 and the tapes 6, and by said rollers 21 is held down on said tapes, and is caused to feed forward until arrested by a first set of spring-actuated stop fingers 22 mounted on the transverse bar 22 (see Figs. 3 and For the usual cheque-sheet, containing in all three cheque blanks, there are three sets of stop fingers for the three different printing positions,namely, a set 23 for the no first position, a set 23 for the second position, and a third set 24 for the third position.

The first set of stops or stop fingers 23 and the second set of stops 23 are for convenience of construction mounted on the same pivoted bar 23*, as best shown in Fig. 3 and the third set of steps 24 is carried by the pivoted bar 24; (see Fig. 3).

Fingers 22 arrest the cheque sheet in advance of the first printing position; the 3120 and 24 respectively, projecting-from rods shoulder 42, in front of which clamp mem- 22, 23 and 24, as shown particularly in Figure 2. These cams- 22 23 and'24 are all mounted on a longitudinal cam shift 25, driven from shaft 17 by a sprocket chain 26 and bevel gears 27 (Fig. 1), suitable sprocket wheels 28 and 29 and a shaft 30 being of course provided; and the cams 22", 23 and 24 have appropriate rises to operate the stop fingers as desired.

For properly positioning the cheque sheets laterally and holding them during the printing operations to insure that they shall be printed upon at precisely the desired position, a lateral positioning device is pro vided. In the particular machine illustrated in the drawings, this positioning and holding device comprises a clamp consisting of members 31 and32, of which 32 is pivoted on 31, (both of these members being longitudinal with respect to the direction of motion of the paper through the machine) member 31 being mounted to slide back and forth (laterally of the machine) through a small distance. on rods 33. This sliding motion is determined by a cam-disk 34, on shaft 25, which disk has three projecting cam-lugs, 36, 37 and 38, each adapted to engage and move to the left (of Flgures 8 and 9) a member 39 secured to clamp member 31, such motion being-against the pressure of springs 40. The cam-lugs 36,

37 and 38 act on a projecting lug 41 of member 39. Figure 9 shows the clamp in what may be termed its extreme or right-hand position, while Figure 8 shows the cam lug 37 in the position of having moved the slide 39 to the left, said cam-lug being about to disengage the lug 41 and so to permit the springs 40 to return the clamp to the right. Referring further to Fig. 9, where the registering device is shown at the end of its lateral movement toward the sheet, the jaws or clamps 31 and 32 are open but are about to close, as the pin 44 is ready to leave the tail or extension 43. As soon as the jaws have closed upon the sheet, they are drawn back by one of the cam- lugs 36, 37 and 38, carrying the sheet with them'into the exact printing position, substantially as indicated in Fig. 8. In this figure the position of the parts is approximately just after the printing has been done, for the pin 44 of the cam 34 is ready to open the jaws to allow the printed sheet'to be advanced to the next position. This opening of the jaws takes place just before the stop fingers rise, as

otherwise the running tapes would tend to twist the sheet. It is to be understood that during each printing operation the registering device, firmly holding the sheet, remains stationary, thus insuring the correct printing position of the sheet.

As shown particularly in Figure 10, clamp member 31 has, near one end, a stop her 32 moves. This member 32 has a rearwardly-projecting tail 43, adapted to be acted upon by pins 44 projecting from camdisk 34. These pins are so positioned that upon movement of the clamp 31-32 to the right (of-Figures 8 and- 9) the clamp is open, and therefore as the clamp so moves the edge ofthe cheque-sheet encounters the .the clamp members 31 and 32, such as a spring adapted to move the pivoted member 32 into closing position when the pin disengages the tail 43.

For inking the type, inking rollers 45 are provided on a shaft 46, extending transversely of the machine, and mounted in bearings in arms 48 pivoted at 48 to slides 49 which operate in ways 47, being reciprocated by a link 50,. a cam-follower arm 51, and a cam 52 on shaft 17. Ink-distributing rollers 53 and 54 are also provided, together with springs 55 which tend to holdrollers 45 against rollers 53. The rollers 45, 53 and 54 are adjustable laterally of the machine, and so are adjustable to different positions of the type-faces to be inked; also, because each set of rollers 45, and 53, and 54, com prises several rollers, different colors of ink may be used on different rollers.

The cheque sheets, after the printing of them is complete, are lifted from the tapes delivery table 3.

The feed-tape rollers 7 are driven from driving shaft 4 by sprocket gearing comprising a chain 61. The ink-distributing rollers 53 are driven from shaft 4 by a belt 62. Shaft 17 is driven from shaft 4 through gears 63 and 64 and a clutch 65 controlled by a pedal 66. The clutch is indicated diagrammatically only, as various types of clutches suitable for the purpose are well known. Shaft 67 for cam 59 is driven from shaft 17 by sprocket gearing including a chain 68.

The operation of the machine is as follows: The various moving parts of the machine being in motion, cheque sheets fed one by one by hand from table2 to the feeding tapes 6, are fed forward thereby until arrested by the first set of stops, 22. At an appropriate time, determined by cam 22*, these fingers 22 are lifted, and the cheque sheet then against said fingers is fed forward by tapes 6 until arrested by the front ends of stop fingers 23, the cheque sheet being then in the first printing position. The positioning clamp 31-32, then operates, positioning the sheet laterally, and the crosshead 11 descends, printing the first cheque blank of the sheet. As the cross-head 11 rises, the clamp 31- 32 releases the sheet, if it has not done so already, and the stop fingers 23 move so that the front ends of said fingers release the sheet and the rear ends of stop fingers 23 are in position to stop the sheet in the second printing position, and the tapes 6 feed the sheet forward until it is arrested by the second set of stop fingers 23. Again the lateral positioning device operates, and the printing head 11 again descends, printing the sheet in the second printing position. The printing head then rises, the fingers 23 are operated to release the sheet, and said sheet is again fed forward until arrested by the third set of stop fingers 24; after which the lateral position ing device again acts, the printing head descends and prints the sheet in the third position, and then rises, and the now-finished sheet is fed forward by tapes 6 over delivery fingers 56, which then deposit the sheet, face downward, on table 3. During these various operations the inking device has been operating at suitable times, and as previously described. As soon as the sheet has passed the first set of stop fingers, 22, another sheet may be introduced and will be fed forward until arrested by fingers 22, where it will be held until the appropriate time for its release. These fingers 22 tend to square the sheet, so that when fed forward it will be presented properly under the printing head; and the lateral positioning device obviates the necessity-of particular care in introducing the sheet in precisely the proper lateral position. Very little skill in the feeding of the machine is required, therefore.

As previously stated, the registering device remains stationary during the period in which the printing takes place for each position of the sheet. This interval is, of course, very short, because the printing only takes a moment or two. After the printing has been done on the sheet in its second position, the fingers 23 and 23', which for convenience are shown mounted on the same shaft 23*, assume a middle or neutral position, as indicated in full lines in Fig. 3. This permits the sheet to pass beneath the stops 23 and '23 into the third printing position against the stops 24. The three positions of the stops 23 and 23', as indicated in by those skilled in the art. Further descrip-' tion on this point is believed to be unneces sary.

One or more type carriers, or type chases, as they are usually called, are mounted on the transverse printing bar 11 in such manner as to be adjustable laterally thereon. In the drawings, T have shown two printing chases mounted on the bar 11; a chase at the right end of the bar (see Fig. 11) and a chase 70' at the left end of the bar (see Fig. 5). Although the type chases 70 and 70' are not shown in the same figure, owing to the fact that in Figs. 5 and 11 the printing bar 11 is broken away for clearness, their disposition on the bar 11 will be well understood. Of course, any number of type chases may be used, depending upon the printing to be done on the sheets. For instance, the chase 70 may be usedfor printing a customers name at the left end of the check and the chase 70 may carry an ordinary numbering machine for numbering the stubs of the check sheets. Usually there will be a third chase also carrying a numbering machine for numbering the checks in correspondence with the numbering of the swung upward about its hinge 12 into position to give access to the type. The ready adj ustability of the type chases on the transverse printing bar 11 is an important feature of my invention. As is well known, there are many different sizes and styles of bank. checks and the adjustment of the type chases for one size or style of check would not do for a check of a different size or style. It is an easy matter to so adjust the type chases on the printing bar 11 as to bring them into the correct printing position for each size and style of check. In this way the requirements of successive orders are quickly met and with a minimum of ex= pense.

Although I have herein shown and described a specific machine, I would have it clearly understood that T have done so by way of illustration and not by way of restriction or limitation. As far as Tam aware, I am the first to invent a practical, successful machine for automatically printa o mg upon a sheet a series of successive 1mpressions from the same type, the sheet being held in adjusted position for each printing operation. Doubtless, the principles of my invention may be carried out mechanically in other ways than that herein set forth without departing from the scope of the invention as defined in the appended claims.
