PAYNE, OF ROCHESTER, NEW YORK, ASSIGNORS TO THE TODD COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK APPARATUS FOR PRINTING NEGOTIABLE PAPER Application filed October 18, 1926. Serial No. 142,194.

The present invention relates to apparatus for printing negotiable paper, the object being to provide more particularly an improved apparatus for printing upon sheets containa: ing blank checks, drafts and the like, the signature of'the maker of the checks or some other identifying mark at the time of issuing the checks whereby to render them negotiable, or printing in conjunction with the signatures an identifying mark or character which will make duplication or forgery of the checks or drafts extremely diiiicul A further object of the invention is a provision of'apparatus of this character which can be economically employed by banks,

corporations, manufacturers and others having relatively large payrolls, who desire to avoid the risk and inconvenience of handling large sums of money in paying off their em- :a ployees and who find the signing of the checks, in large numbers, in theordinary way an inefficient, troublesome and unsatisfactory method of distributing the wages of the men from week to week, or as often as may be required.

A further object is to provide an improved printing machine of the class described herein and one which is convenient to operate, efficient in service and of comparatively sun- 3 ple construction.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being 3:, pointed out in the claims at the end of the specification.

The present invention provides one form of mechanism for advantageously carrying out the method described and claimed in our divisional application, Serial No. 343,436, tiled February 28, 1929.

The present apparatus for signing checks, drafts, bills and other negotiable paper is de- 2 1,7s1,7ae

signed for applying or printing on sheets, of a given size, a number or series of blank checks of the usual form which may be printed in relatively large numbers ready for use when desired. The next step is that of simultaneously applying upon the checks of each sheet, preferably by printing, a signature of the maker and a suitable identifying mark, seal, or character such as a picture or photograph of the maker, this being done preferably at the time of issuing the checks and upon a protective background such as the series of closely related lines shown in conjunction with the signature and picture indicated in Figure 15, which renders duplication of the check more difficult. The amounts for which the checks are to be issued and the dates and names of those to whom they are made payable can then be filled in, or if preferred this can be done previous to applying the signatures. By s1- multaneously applying or printing a facsimileof the signature of the maker of the check and his picture or that of an ofiicer of his company, or any suitable identifying character, the checks are rendered ne otiable and recognition of this fact can be 0 tained from the bank on which the checks are drawn. This method of rendering the checks negotiable not only saves the maker the time required for signing the same, but it renders duplication or forgery more diflicult since not only the signature must be duplicated but the picture of the maker as well, or whatever character may be employed in conjunction with the signature. Forgery under these conditions is far more difficult than in the present method of signing checks, where only the signature has to be forged. With the present method the would-be forger is put to the expense of employing an engraver to make the necessary plates for printinglthe signature and picture, thereby laying imself liable to detection. It will be understood that the machines for printing the checks will be kept under lock and key in the care of some responsible person who can be trusted to prevent unauthorized use of the machine.

Referring to the drawings, 10 represents the base of the machine to which is suitably bolted'to an upstanding frame 11 at the left hand end of the machine and an additional for each printing unit, the same being adapted to carry the ink supply rolls 18 in a manner described hereinafter. The panels 17 are supported by a longitudinally extending bar 19 having a groove or slot therein to receive the lower edges of the panels as shown in Figure 4, the upper edges of the panels being disposed upon a somewhat similar bar 20. Both of the bars have their opposite ends suitably secured to the frames 11 and 12. A vertically disposed panel 21 is positioned at the right hand end of the bars 19 and 20 for closing the front of the com artment containing the drive mechanism s own in Figures 7 and 8.

Mounted on a lateral extension 10. of the base 10 is a small electric motor 22 for driving the revoluble parts of the printing and check" cutting mechanisms, which wilh be hereinafter described.

In the present machine there are provided five separate printing unitsfor simultaneously printing upon a single sheet, one of which is indicated at 23, five signatures of the maker of the checks shown by way of example at 23 and a corresponding number of photographs indicated at 23*, Figure 15. It will be understood of course, that the number of printing units may be increased or decreased as desired according to the demands of those using the machines. The sheets 23 are preferably of a width corresponding to the length of the individual checks and of a length suflicient to afford anumber of checks corresponding to the number of printing units.

As all of the printing units are of the same construction, a description of one will suffice for all. These units are mounted on upper and lower longitudinally extending shafts 24 and 25 respectively. The upper shaft has its left hand end suitably journaled in the frame 11, its opposite end being keyed Within the hub 26 of a gear 27, supported by a stub shaft 28 journaled in the frame 12 as shown in Figure 3 and ada ted to bedriven by mechanism which will e subsequently described. The lower shaft 25 has its opposite ends journaled in the end frame members 11 and 12 and is adapted to be driven by the upper shaft through the medium of suitable gearing which will presently be described.

:A suitable number of'intermediatebear ings are provided for taking the upward thrust on the shaft 24, one of which is indicated at 29 in Figure 3, said bearings being suitably supported by transversely extending plate members 30 overlying the shaft and having their opposite ends connected with the front and rear walls of the casing.

The printing forms or plates upon which the signatures and photogra hs of the maker of the checks are etched or reproduction preferably constitute thin zinc plates one of which is indicated at 31 in Figure 10. The plates are in the form of circular bands memes 1 clamped upon the rollers 32, fixed upon and adapted to be driven by the shaft 24.

The signatures 23 and photographs 23 are transferred from the plates 31 to printing strips or blankets 33 suitably clamped in the grooved faces of the blanket rolls 34 which are supported by the shaft in a manner which will subsequently be described.

The platens for holding the sheets in contact with the blanket rolls are indicated at 35 in Figure 4, each being free to rotate upon a short shaft 36 carried by an arm or lever 37 pivoted upon the base 10 at 37*. The free end of the arm 37 is slotted to receive a pair of downwardly projecting studs 38 suitably connected at their upper ends to a support 39 preferably formed integral with the base 10. Coil springs 40 carried by the studs 38, Figure 4, serve to press upwardly on the arm to afford the desired pressure between the platen and the sheets to be printed when the latter are run through the machine. An adjusting screw 41, Figure 3, is threaded through. the arm 37 between the studs 38 and engages the support 39 to limit the upward movement of the arm, and consequently the pressure of the platen upon the-blanket roll when the paper is fed between the two. The platen operates through an opening 43 in a tray 44 upon which the sheets to be printed are properly placed for movement through the machine by the blanket rolls when rotated in a clockwise direction as viewed in Figure 4. An upper guide plate 45 for the sheets is provided with an opening 46 through which the blanket rolls operate, said'plate being curved upwardly at the front of the machine where it is secured to the bar 19. It is flanged upwardly at its opposite side and suitably connected with the rear wall of the casing.- The tray 44 is flanged downwardly at its front and rear edges to receive a plurality of supporting rods 47 which extend transversely through the base, by which they are supported. The tray is provided with an adjustable positionin bar 48 for the printed sheets of paper an carries depending pins or projections operating in slots 49 in the tray andserving to hold the bar in proper alignment when adjusted inwardly or outwardly to the desired point on the tray. The pins carry thumb nuts 48" by which the bar is clamped in the desired position. The tray is provided at its right hand end with an adjustable positioning pin 50 for effecting the proper alignment of the sheets with the printing units.

The plate rolls 32 carrying the printing forms 31 have extended hub portions 51, Figure 3, which form abutm'ents for a pair of plates 52, the shape of which isbest indicated in Figure 4. Both the upper and lower shafts 24and 25 extend through these plates. The plates are provided with hearing hubs 53 and 54 and are held in proper position on the shafts by contact with the ends of the hub 51. The plates form supports for the inking rolls 55 which distribute the ink to the printing form 31, five of the rolls being shown in Fig ure 4 in position to contact with the printing form when rotated by the shaft 24. The rolls have trunnions at their ends which are guided in slots 56 in the plates, the rolls being yieldably held in engagement with the printing form by two upper rolls 57 and two lower rolls 58 each having trunnions free to move in slots formed in the plates 52. Therolls 57 are yieldably held in the position shown in Figure 4 by a pair of springs 59 connected at their inner ends to the plates 52 and at their outer ends to a pair of arms 60 fixed on the trunnions of said rolls. The two lower rolls 58 are yieldably held upon three of the inner rolls 55 by a single roller 61, the trunnions of which are free to move in slots formed in the plates 52, said trunnions carrying arms 62 with which are connected the outer ends of springs 63 which have their inner ends suitably connected with the plates 52 as shown in Figure 4. The trunnions for the inner set of inking rolls 55 are provided with small rollers 64, Figure 3, adapted to travel on the flanged portions 65 of the plate roll 32 whereby said inner rolls are supported for contact with the printing plate 31. The rollers 64 are preferably made slightly smaller in diameter than the inking rolls so that the latter will be free to engage the printing plate under the action of the springs 59 and 63. The supply roll 18 is carried by a U-shaped lever 66 into which projects a lug 67 on the inner face of the panel 17, the lug carrying a pin 68 upon which the lever is pivoted. A torsion spring 69 wound about the pivot pin tends to swing the lower end of the lever inwardly to move the supply roll into engagement with the inking roll 61. The supply roll is normally held out of engagement with the roll 61 by a latch 70 pivoted upon the upper end of the lever and projecting through a slot in the panel 17. The latch is provided with a shoulder portion 71 which normally bears against the inner face of the panel 17 as shown in Figure 4. To release the latch it is only necessary to raise its outer end slightly, at which time it will be projected through said slot by the action of the spring 69 which will throw the supply roll 18 into engagement with the inking roll 61,

from which ink will be carried to the remaining rolls as will be understood. The supply roll may be removed for inking whenever desired by removing the panels 17 which are held in position by pivoted guards or latch members 72 as shown in Figures 2 and 4.

The blanket rolls 34 are each rotatably mounted upon a. pin 73 extended through hubs 7 3 of the roll, the pin being supported by a screw 74 projecting into each end thereof. The studs are carried by a pair of arms disposed inwardly of the plates 52 and pivoted thereon at 76, Figure 4. The plates 75 constitute adjustable arms for supporting the blanket roll to permit it to be adjusted toward and from the plate roll whereby to regulate the pressure between the printing plate 31 and the blanket 33. This is done by means of an adjusting screw 77 which extends through an outwardly turned toward or from theplate roll according to' whether it is desiredto increase or decrease the pressure between the plate and the blanket. A locking screw 80 is threaded through the lug 78 to hold the arm 75 in adjusted position. The arm in addition to being secured to the plate 52 by the pivot pin 76 is held by a second headed pin 81 extended through a slot in the plate 52 as indicated in Figure 4.

The plates 52 of 'each blanket roll are provided with suitable connections 82 for bracing and tying them together as indicated in Figures 3 and 4. The blanket rolls each carry a gear 84 secured at one side thereof by three screws 85 threaded into a corresponding number of bosses 86 formed upon the roll, the gear being disposed inwardly of one of the arms 75. The gears 84 mesh with a series of smaller gears 87 fixed on the shaft 25 which serve to drive each of the blanket rolls. The shaft 25 carries a gear 88 at its right hand end which meshes with a gear 89 of the same size rotatably supported by a stud 90 suitably secured upon and projecting inwardly from the end frame 12, Figure 3. The gear 89 is driven by a gear 91 loose on the stub shaft 28, Figures 3 and 7. The gear 27 which. drives the shaft 24 and'the plate rolls thereon is driven by a gear 92 having a hub, 93 to which the gear 89 is fixexhthe hub being ournaled upon the stud 90 carriedby the frame 12. Thus it will be seen that by rotating the stub shaft 28 the gear 91 when coupled therewith as hereinafter explained, will drive the gear 89 which in turn will drive the gear 88 on the shaft 25 for rotating the blanket rolls. The shaft 24 will be driven at the same speed as the shaft 25 since the gears 27 and 91 are the same size, the gears 88, 89 and 92 being also the same size.

Secured to the end frame 12 is a gear casing 93 carrying a worm 94 on a shaft 95 haV- ing its opposite ends suitably journaled in bearings formed upon the casing. The shaft 95 is connected with the motor shaft 96 by a suitable'coupling 97 of a well known type, the same being shown in Figured The worm 94 meshes with a worm wheel 98 fixed upon the stub shaft 28, the outer end of which is journaled in the casing 93 and the inner end i being journaled in a sleeve 91 fixed to the gear 91, said sleeve having projections 100 entering notches in the hub of a disc 101 on the arbor 28. The disc carries a driving pawl 102 pivoted thereon for 'movement into engagement with a ratchet wheel 108 011 the worm gear 98. The driving pawl carries a pin 104 projecting through an opening 105 in the disc and is engaged by the forked end of a dog 106 pivoted upon the disc. A stop pin 107 is carried by the disc for engagement with the dog, the latter being normally held against the stop pin by a latch 108, Figure 8. With the latch in the normal position shown in Figure 8, the'pawl 102 is held out of engagement with the ratchet wheel to permit rotation of the motor without operation of the printing units. Upon'release of the latch a spring 109 connected with the dog serves to move the latter upon its pivot which in turn swings the pin 104 downwardly and moves the pawl into engagement with the ratchet wheel whereby the disc 101 is coupled with the stub shaft 28 to be driven by the latter. The latch is carried on the inner end of a rod 110 which is journaled in the frame 12 and casing 93, and which projects from the latter as shown in Figure 7. The latch carries an arm 111 adapted to engage the wall of the casing which forms a stop to limit the downward movement of the latch. A dog 109 pivoted loosely on the rod 110 en-' gages a notch in the periphery of the disc 101 to prevent the backward movement of the'latter under the influence of the spring 109. A spring pressed plunger 110 serves to hold the dog in the notch. The outer end of the rod is provided with an arm 112 which carries an inwardly turned portion 113 at naled in brackets 122 on the base 10, Figure 3. The lever is provided with an offset portion 123 forming a support for one end of a trip bar 124, the other end of the bar being carried by an L-shaped plate 125 secured to the inner end of the rod. Depression of the trip bar causes the lever 120to push up on the link 119 which swings the lower arm of the bell crank lever forwardly thereby exerting a pull on the arm 112 of the rod 110 whereby the latter is rocked to release the latch 108 from engagement with the dog 106 to permit the spring 109 to move the operating pawl 102 into engagement with the teeth of the ratchet wheel 103. In this manner the worm wheel is coupled with i envae and the latter is made to swing the pawl 102 out of driving engagement with the ratchet wheel. at the end of each rotation of the disc 101. A light spring 12? connects the bell crank lever 116 with the front end of the lever, 114 whereby the rear end of said lever is held in operating engagement with the arm 112 of the latch rod 110. With the driving mechanism described above one sheet containing the printed checks can be fed through the machine to receive the signatures and photographs indicated in Figure 15, each time the finger bar 124 is depressed by the operator.

The upper and lower knives 128 and 129 for severing the checks from the printed sheets as the latter are passed through the machine are best indicated in Figures 4 and 13, and are preferably in the form of discs mounted on shafts 130 and 131 with their cutting edges arranged to be rotated one adjacent the other. Each of the knives is clam ed between a pair of collars 132 ad.- justa le longitudinally upon the threaded portions 133 of the shafts so that their cutting edges may be properly adjusted one with respect to another from time to. time. The different sets of knives are preferably staggered one with respect to another, as in dicated in Figure 13, so that by providing suitable thrust bearings for one shaft the knives thereof, through engagement with cer-. tain of the knives of the other shaft, will prevent longitudinal movement of the latter, thus making it unnecessary to provide thrust bearings for both shafts. The ends of the shafts are journalled in suitable brackets 134 and 135 which are in the form of housings and which are bolted respectively to the frames 11 and 12 at the back thereof. Dis posed within the housing 134 are upper and lower gears 136 and 137 meshing one with another and being keyed on the shafts 130 and 131 respectively. A. cover plate 138 is carried by the housing 134 to protect-the gears therein. The upper shaft 130 is provided at its opposite end, within the housing 135, with a gear 139 driven by an idler 140 which in turn is driven by a gear 141 meshing with and driven by a gear 142 on the stub shaft 28. The idlers 140 and 141 are suitdriven by the motor will drive the knife.

shafts continuously, the gearing being so proportioned as to drive the knives at a somewhat greater speed than that of the printing rolls so that when the advancing ends of the sheets pass. between the upper and lower sets of knives the latter will tend to exert a slight pull on the sheets which is advantageous in thatthe sheets are thus kept slightly tensioned during the printing operation.

The severed checks indicated at 144 are received as they pass from the knives by the holding device shown in Figure 14 which comprises a rack having a plurality of pockets formed from a series of bent plates 145 having flanges at their lower edges supported by a base plate 146, the flanges being extended beneath lugs 147 struck upwardly from the base plate, the latter being provided with suitable supports 148 preferably formed of rubber or other relatively soft material. 85

The rack, though shown separate from the machine proper may be suitably connected therewith if desired, both the rack and machine being carried by a suitable support such as a table, not shown. The relation of the rack to the machine is such that the upper edges of the plates 145 will occupy positions a little to one side of the knives so that all of the checks severed by a given set of knives will fall into a common pocket. This is due to the unbalanced position of the checks upon the plates 145 when the severing operations are completed, as indicated in Figure 14. The length ofthe pockets is preferably a little less than that of the checks so that the ends of the latter will project somewhat beyond the pockets in order that the checks may be more easily grasped for removal by .the fingers.

1n positioning the printed sheets upon the tray, they are first inserted between the latter-and the plate 45, the back edges of the sheets being then brought into engagement with the rear edge of the positioning bar 48. This is done to insure proper positioning of no the signatures and photographs on the checks when the sheets are run through the machine, it being understood that the blanket rolls are operated from the same starting point for each sheet printed, and that consequently the printing will occupy the same relative position on all of the checks.

To prevent the possibility of the sheets being passed into engagement with the knives, when positioned in the machine, a series of guards 149 are projected through openings in the back of the casing, said guards having their inner ends sultably connected with a rock shaft 150 extending longitudinally of the casing, Figure 4, and having -their opposite ends journaled in the end on the end frame 12 and adapted to be driven I by a smaller gear 1 55 on the right hand end of the shaft 25, Figure 3. The cam is so arranged as to depress the arm 151 whereby to rock the shaft in time to raise the guards before the sheets reach them.

A cover plate 156 is positioned over the knives as indicated in Figure 4, and carries at its rear edge a suitable number of guards 157 which project forwardly between the knives to prevent the sheets from passing upwardly beneath the cover plate.

At certain times it is desirable to prevent the platens from contacting with the blanket rolls, as when the blankets have been freshly inked. At such times the arms 37 which support the platensare moved downessential in a device of this kind.

wardly a slight ainbuntby a set of links 158 which have slots in their upper ends to receive laterally projecting pins 159 on the arms. The links are carried by a shaft 160 journaled in the ends of the base and on which are mounted eccentrics 161 rotatable in openings formed in the lower ends of the links through which the shaft extends. The links and eccentrics are disposed between oppositely positioned collars 162 and 163 on the shaft, the eccentrics being attached either to the shaft or to one of the collars as desired, preferably the latter. Rotation of the eccentrics to lower the links is effected by giving the crank 164 on the outer end of the shaft substantially a half turn.

The plate roll shown in section in Figure 10 has angularly disposed portions 165 and 166 for receiving the ends of the printing plate. A clamping member 167 is provided with a rounded edge portion 168 which is adapted to force one end of the plate into a circular groove formed in the portion 165 of the roll, the member 167 being held in clamping position by a screw 169. The opposite end of the plate is disposed upon a slide 170, and is secured thereto by a clamping member 171, which also has a rounded edge portion for pressing the end of the plate into a groove formed in the slide. A bar 173 is suitable secured upon the portion 166 of the roll and extending therethrough is in adjusting screw 174 which is threaded into the slide for the purpose of adjusting the same whereby to tighten and properly ten sion said plate. By this means a very fine adjustment of the plate is afforded which is The blanket rolls 34 are provided with the same form of 'adjusting means for the blanket strips as indicated in Figure 4.

-f-=" In order to prevent overrunning of the gears for driving the shaft 25, and those thereon for driving the blanket rolls, a suitable brake is provided which preferably comprises a pair of yieldable arms 175 having suitable lining strips 176 disposed in engagement with the opposite sides of the shaft, Figmemes ure 9. The arms are carried by a block 177 supported preferably by a stud 178 projecting inwardly from the end frame 11 at the left hand end of the machine. The arms are yieldably held in engagement with the shaft by a spring 179 on a bolt 180 extending through the other ends of the arms, one end of the spring being seated upon the upper arm and-the other upon the head of the free end of the bolt.

The electric switch for controllin the motor is indicated at 181, and may be 0 any well known type. It is preferably disposed on the end frame 11 and is provided with the usual arm or lever 182 for opening and closing the switch. The arm isprojected between two operatinglugs 183 and 184 on a switch control plate 185 mounted to swing upon the shaft 24. The plate has associated therewith a disc 186 rigid on the shaft 24 and havingv a notch 187 in registry with a similar notch 187 in the plate 185. The notches are adapted to receive the bolt 188 of a lock 189 of any preferred type, preferably a key lock, the key receiving portion of which projects through the frame 11 as indicated at 190. The bolt 188 serves to lock both the shaft 24 and the switch plate when the machine is not in use. The switch member 182 is shown in open position in Figure 9, and in this position' the notches 187 and 187 are in registry with the lock bolt 188, which when moved into the notches prevents closin of the switch and unauthorized operation 0 the machine. When the bolt is in release position, as shown, the plate 185 may be swung to switch closing position by moving the operating knob or handle 191 thereon, in the slot 192 of the frame 11, tothe right as viewed in Figure 9.

A counter 193 is provided at the right hand end of the machine to furnish a record of the number of checks printed at any given time.

The counter may be of any well known type, and is suitably supported so that it can be read through an opening in the end panel 21 behind which it is disposed. The counter is provided with the usual resetting stem 194 which projects through the end wall 14 of the casing. The counter operating shaft carries an arm 195 with which is connected a depending link' 196, the lower end of which is pivotally connected with an arm- 197,.the latter being pivoted at 198 totheend frame 12. The link carries a roller 199 projecting through a slot 200 in said end frame. The roller lies in the path of a cam block 201 on the gear wheel 154 driven by the gear 155 on the shaft 25, Figure 3. I For each revolution of the ear wheel the block 201 will en age the rol er and depress the arm 197, w ich serves to effect a downward pull on the link.

indicating wheels of the counter are preferayienvae ably designed to display, at each printing operation of the machine, a number corresponding to the number of checks printed at said operation, being in each case 5 with the present machine.

The counter is provided with a locking lever 203 pivoted on a stud 204 of a housing 205 in which the counter is disposed, and to which it is suitably secure-d. The lever carries a projection 206 which engages in a notch formed in a disc 20? rigid on the resetting stem 194 of the counter. A torsion spring 208 tends to hold the leverin the position.

shown in Figure 11. A rod 209 is provided for holding the lever in locked position when the machine is being operated to prevent turning back of the counter and spoiling the record. The rod has a notch 210 normally in line with the lever 203 for receiving the latter when resetting the counter. The rod has its opposite ends slidably mounted in the end frames 11 ahd 12 and is held in release position with respect to the leverby a spring 211, one end of which engages the frame 12 and the other a 'pin on the rod. The rod is automatically moved to locking position by turning the key of the lock 189 to depress the bolt 188 thereof. In doing this a stud 212 on the bolt rides on the cam surface 213 of a lever 214: pivoted at 215 on the end frame 11 whereby the lower end of the lever is moved rearwardly and its upper end forwardly. The upper end of the lever is pivotally connected to a slide bar 216 guided in a bracket 21? on the frame 11, Figure 12.

The front end of the bar is forked to receive a reduced portion 218 of the rod. The latter is provided with upper and lower beveled shoulders 219 which lie in the path of correspondingly' beveled surfaces 220 on the end of the slide bar, whereby when the latter is moved forward by the lever 214 the rod 209 is forced to the right against the action of the spring 211 and the notch 210 is thus moved out of registry with the counter locking lever thereby preventing any motion of the latter. Upon completion of the printing of a desired number of checks, the switch control plate 185 will be.rotatedback to the position shown in Figure 9 to open the-switch, atiwhich time the bolt of the lock, by turning the key of the latter, will be returned to the notches 187 and 187 to lock the switch control plate and shaft 24 whereby to prevent unauthorized operation of the machine. At this time the s ring 211 will move the rod 209 to the left, which in turn will move the slide bar rearwardly to press the lower end of the lever 214 in position to be operated by the stud on the bolt of the lock when the latter is again moved to unlocked positionr In this position the notch 210 in the rod 209 is opposite the counter locking lever 203 so that the latter can move into the notch when the counter operating stem is I: rotated, the locking lever being pushed back against the action of the spring 208 by the inclined walls of the notch in the disc 207.
