MULTIPLE-WRITING MACHINE.

Application filed September 30, 1919. Serial No. 327,469.

To all whom it may concern:

Be it known that I, FRANK AMos JointsoN, a citizen of the United States, and mmdent of New Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Multiple-\Vriting Machines, of which the following is a specification This invention relates to multiple writing of parts in a machine of this character,-

whereby the documents, such for example as checks may be taken from different stacks or sources, arranged in predetermined groups, fed into position'to be written upon, and finally conveyed from the writing pens to be restacked or grouped in any desired arrangement which is usually the same as that from which they were segregated and formed into predetermined groups'for being written upon. One of the objects of the present invention is to provide improved means for feeding checks from a plurality of stacks and arranging them in groups to correspond to the group arrangement of the pens by which they are to be written upon. Another object is toprovide improved means for correlating the check-feeding and checkstacking operations with the operation 'of the pen group. Other and more specific objects of invention will appear in the specification and be pointed out in the claims, referene being bad to the accompanying drawings which exemplify my invention and in which,

Figure 15 is a similar top plan view show-'- ing parts in changed positions.

According to the embodiment of my invention shown on the drawings, the main frame of the machine, as shown in Figure 1, includes three pairs of uprights 1, 2, and 3. Throughout the following description, the front end of the machine will be taken as that toward which the documents move in theirpassage through the machine. Said documents will therefore be considered as entering the machine at the rear end. The right side will therefore be considered that on the observers right as he faces forward, the left side being toward his left hand as he faces forward. Surmounting the rear-- uprights 1, are left and right side frames 4 and 5, the forward ends of said side frames being connected by left and right side bars 6 and 7 (see Figures 1,4, and 8) to the rear end of the main bed plate 8 which surmounts the paired uprights 2 and 3. As shown in Figures, a crank 9 provided with a hand grip 10, is journalled upona stud 11 which is mounted in the side frame 5. Also journalled on the stud 1 1 and adapted to be rotated by'the crank 9, is a pinion 12 which meshes with a spur gear 13, said spur is journalled in the side frames 41 and 5. Secured to the left end of cam shaft 1% and arranged outside the side frame a, is an eccentric whichhas running contact with a cam lever 16. The cam lever 16 oscillates upon a pin 17 and carries a pin 18 upon which is mounted a pawl 19 provided. with a hand grip 20 by means of which said pawl may be thrown into and out of engagement with a rack 21 which is reci roca bly mounted on the side frame at. for yieldably holding pawl 19 in engageinent with rack 21, are provided by a spring 22 which has one end connected to the pawl 19 and its other end attached to a flange on the side frame t. A dog 23 provided with a hand grip 24 is pivotally mounted on a stud 25 and acted upon by a spring 26 for holding it in en agement with rack 21. Pivotally connected at 27 to the forward end of the rack bar 21, is a cam bar 28 which may be held at a suitable inclination to the horizontal by means of a link 29 which is pivotall connected at 30 to the rear end of com ar 28. it slot 31 in the lower end of link 29,- pe'rmits a vertical adjustment of cam bar 28. The cam. bar is held in any'desired position by means of a thumb nut 32 which clams the link 29 tothe ratchet bar 21. rack bar 33 has a rounded lowerend 3% which is adapted to bear on the inclined cam bar 28. The cam bar'33 meshes with a spur pinion 35 keyed to a shaft 36, and

serves only to tranit, power to said shaft 36. Near opposite ends of said shaft, are

attached to a table or platen t0 so that as v the cam bar 28, shown in Figure 5, is moved forward, the table or platen 40 is gradually elevated for apurpose to be hereinafter explained. As shown in Figure 3, the platen or tabledOis in the present embodiment of my invention, provided with a plurality of,

longitudinal partitions All, said partitions being adaptedto provide suitable compartments for piles or stacks of checks or other documents which may-he arranged in said compartments in any .des' ed order... Referring now to Figures 3 o 7 inclusive, a rock shaft 42. which is .journalled in the reariends of- side frames 4 and 5. has keyed thereto a lower cam arm 43 and an upper cam arm tt-which are controlled by cams 45-and 46 respectively which are keyed to the camshaft 14; Menu upon the rock shaft 42 arelatera'lly spaced lever arms 47 f and 4:8 within the upper ends of which is journalled a. secondary rock shait t9 which i s adapted torock on its c axis while said axis being moved to. and fro in a 1 cans A tort operating anteater direction longitudinal to the feed. According to the present embodiment of my invention, five reciprocatory bucklers are pivotally-mounted upon the secondary rock shaft 49, the lateral disposition of said grippers corresponding to the compartments which contain the checks or other documents C. The forward ends of the bucklers 50 are provided with weights 51, said weights being adjustable along the bucklers 50 and held by set screws 52 in any positions to which they ma be adjusted. The downwardly deflectc end of each of said bucklers 50 is provided with afriction pad '53 for adapting it to displace a check or document from the top of the pile or stack. Adjacent opposite sides of the machine are a pair of levers 54 which are keyed to the secondary rock shaft 49 and carry in their forward ends a bar 55 which is adapted to engage the under'edgcs of the bucklers 50 for lifting them from the documents at certain times in the feedingoperation. Projecting rearwardly from the rock shaft 49 and keyed thereto is a lever arm 56 which is pi'votally connected at 57 to the upper end ofa connectin rod 58. Said rod 58 is provided with a s ot 59 in its lower end through which projects a stud 60, carried by the rear.

wardly; projecting arm of a cam lever 61 which oscillates about the'axis of rock shaft 42. This construction permits the rock shaft 49 to be turned sufliciently to raise all the arms or bucklers 50 out of the way, for introducing the checks G into the machine. ca'plp g2, 1

, e e'rring more esecial to Fi rest and 7, 'acam 63, ich i: keyed l o the cam shaft Moperatesupon one end of a cam lever 64 which is pivoted on a stud 65 and provided with a spring 66 which holds the camlever in running engagement with the cam 63.. 'The forward end of the cam lever ea isconnected by a link 67 with a reciprocable slide 68 provided at its upper The cam lever 61 r is moved vby a end with a rack 69 which meshes with a spur pinion 70, said spur pinion being keyed to a transverse shaft 71 which carries a plurality of movable stops 72 which are periodically moved into and out of the position shown in Figure 6' in which they hold the forward edges of the checks or documents C while they are being buckled in the manner indicated in Figure 6. After each group of five checks or documents has been thus buckled and before their rear edges are released by the bucklers 50,'the upward movement of the slides 68 serves to move the stops 72. to release position in which their forward edges are caused to have been thus described. As shown in full lines in Figure 3 and in-dotted lines in Figure 4, a bracket or hanger 73 carries a stud 74 on which is pivotally mounted a cam lever 75, said cam lever being provided with a cam roller 76 which travels in a profile cam slot 77 formed on the inner surface of gear 13. Cam lever 75 isconnected by a link 78 to the rear end of a rack bar 79 which, as shown in Figure 8, is reciprocably mounted on a guide bar 80. The reciprocable carriage upon which are mounted the document ippers, comprises a spur gear 81 which is keyed to a, shaft 82, said shaft 82 having also keyed thereto oppositely arranged spur gears 83, 83 which mesh with fixed racks 84, 84. The shaft 82 is journalled within a, tubular bar 85 which is rigidly connected to a tubular bar 86 by means of "side frames 87. Said car riage is supported independently of the gears and racks by means of rolls 88, 88 journalled on opposite ends of shaft 82- and on opposite ends of tubular bar 86. Said rolls 88 run on tracks 89, 89. In the present embodiment of my invention, five document grippers are mounted on the carriage and arranged to correspond to the relative positions of the piles or stacks from which the documents are to be fed off. Each of said grippers includes a plate 90 supported by the tubular rods 85 and 86, said plate being provided with a downwardly presented jaw 91. N movable gripper jaw 92 is formed by the deflected lower end of a bar 93 Which'is movably connected to the plate 90 by a link 94 and one arm of a lever 95. Said lever 95i's fulcrumed at 96 upon an upwardly projecting portion of the plate 90. A spring 97 tends to retain the movable gripper jaw in close contact with the fixed gripper jaw. Journalled in the carriage side bars 87, 87, is a rock shaft 98 which extends through the plates 90. Secured tos aid rock shaft are lever arms 99 which are respectively provided with pins 100 adapted to engage cam surfaces 101 formed on levers 95. Depending from the rock shaft 98 is an arm 102 which is adapted w rock said shaft by having its travelling movement with the carriage intercepted. by fixed and movable stops. of the fixed-stops is disposed at 103 adjacent the rear end,of the carriage movement while a' second fixed stop 104 is disposed adjacent the end of the longer forward movement of said carriage. Interposed between these fixed stops, is a movable stop (see Figures 1' and 5) which is pivotally connected at 106 to one arm of a camlever 107 which is fulcrumed on a stud 108 in the side frame 4. A cam 109' (see Figure 3) is provided with suitable connections for operating cam lever 107. In or documents. therebetween. Each As shown in Figures 2 and 8, one

of'the feeding action 'of the carriage, suitable means are provided for each gripper to indicate whether -more or less than one check is being fed off by that grip er. For this purpose, in the present embo iment of my invention, a cross bar 110 is mounted upon laterally spaced links 111 to be moved into and out of operative position on studs 112. Mounted on the cross bar'110, are a plurality of lamps 113, one terminal of each-of said lamps being connected by a wire 114 ,to one-pole of a battery 115. The other terminal of each lamp is electrically connected to a spring bar 116 which projects forwardly from the cross ;'bar 110. The spring bars 116 are adapted to yieldably engage contacts 117 which extend through the blocks 118 carried by the plates 90 of the respective grippers (see -Figures 8 9, 10 and 11). Each of the blocks 118 carries on its opposite face, a conducting yoke 119 which is provided with an upper contact 120' and a lower contact 121, said contacts preferably being adjustable toward and away from each other. Arranged between the contacts 120 and 121 is a spring contact 122 which projects rearwardly from the cam lever 95. A wire 123 .connects the spring contact 122 to the other pole of 'ba-tter'y115 so that wheneverthe spring contact 122 is moved into engagement with either of. the contacts 120 and 121 while the carriage is in its rearmost position, an energizing circuit is completed which includes lamp "113, wire 114, battery 115, wire 123, spring contact 122, contact 120 (or 121), yoke'119, contact 117, and

band 116. Referring now to Figures 1,2 and 12, a plurality of endless belts or chains 124 are laterally spaced on the machine to correspond to the reciprocable grippers or carriages. As shown'in Figure 12, each of the endless chains 124, is provided with lugs or pushers 125'which'are spaced longitudinally of the chain a distance sufiicient to accommodate successive of said endless chains 124 runs about a rear sprocket 126 and a forward sprocket 127. The forward sprockets .127 are keyed to a common shaft 128, the left end ofsaid shaft being provided with a pinion 129 which meshes with a gear 130 on a stub shaft 131 which carries a crank 132. The

top surface of themain bed plate 133 of the machine is preferably made to extend from near the forward. edge of the platen or table 40 upon which the stacks of documents are disposed. Near the end ,of the machine and above the; main bedplate, are

"arranged, in the present embodiment of my- .invention, a group ofpens 134 which are carried by a common ,frame 135. Connected to the frame l35,-isa monitor handle 136 by means of which the multiple writing instruments 134 are actuated. Leading from the forward end of the main bed plate133, is an inner guide or plate 137 and spaced outwardly therefrom, 'a plurality of guide fingers 138. This construction provides downwardly presented chutes through which the documents from the multiple writing mechanism, are discharged into pockets or receptacles formed as shown in Figures 1 and 12. A recep-i tacle for receiving the documents thus discharged, comprises a front wall 139, bottom wall 140 and partitions'and end walls 141, said receptacle being mounted on the forward uprights of the machine'by means of bracket arms 142. In the modification shown in Figures 13, 14 and 15. a packing device is shown for handling checks made of verythin paper. For this purpose, the partitions 141 are arranged to provide "compartments of less width than the checks as'shown in the enlarged scale views, Figures 14 and 15. The upper edges of partitions 141 are made of less thickness to form ledges or shoulders 155 upon which the lateral edges of the checks become lodged until they are pressed down on to the packs "as shown in. F1 ure 15. For thispurpose,

a pusher crossead 143 is connected by a I buckled. Briefly stated, the operation of my improved machjine, according to the embodiment shown 'on the drawings is as follows.

For example, single checks arranged in five stacks or piles upon the platen or feed table 40 are to be arranged in double, transverse rows beneath the writing pens 134,

.said checks are then to be signed an oflicial who manipulates the monitor handle 136and said checks are then to be stacked within the receptacles at the end of the machine in the same order in which they were taken from the stacks at the feeding-in end of said machine. As shown in Figure 4, the cam slot 77 comprises a, rearwardly pre- 'sented portion located relatively near to the cam shaft 14, upper and lower portions whichare near the periphery of the cam and a forwardly extending portion which is intermediate in distance between the first mentioned portion and said peripheral portions ofthe cam slot. a

Asthe crank 76WhenJ-in'the position shown in Figure 4-, ill correspond to the reciprocating car pa e or gripper in its forward positionfesi 9 is turned, the cam roller mas er shown in Figure 1. Prior to the parts assuming these relative positions, the bucklers 50 have buckled the top checks of the several piles in the manner shown in Figure 6,

the movable stops 72 being disposed in suit- 76 able position to hold the forward ed es of the checks against displacement. As t e reciprocating carriage or grippers reach their rear-most position, the movable steps 72 are swung into their lowered positions shown 76 in Figure 7 which releases the forward edges of the top checks so that as the buckled checks flatten themselves, their forward edges are extended between the gripper jaws which at that time are held in open position 8t by reason of the pendulum 102 having thrown the caml lever 99 under the cam lever at the forward end of the preceding stroke. During the return stroke of the carriage or grippers, said pendulum 102 85 comes into engagement with a fixed stop'103, and it is moved into the position shown in Figure 7, permitting springs 97 to close the several grippers. If there is a failure in any one of said grippers to grip a cheek an (as shown in Figure 10), the spring contact 122 is thrown into engagement with the lowercontact 121 and the lamp 113 becomes illumined. If, as shown in Figure 11, more than one check has been gripped by the jaws 5 of the gripper, the spring switch 122 will be held in engagement with the upper contact 120, the lamp 113 being likewise energized. Noticing the lamp or lamps, the

operator, by examining the particular gripwe per or grippers, will see whether there is no check present or two or more checks present within each of the grippers. It will be understood from Figure 8 that gear 81 is'of less pitch diameter than gears 83, 83 so that 5 the reciprocatory movements of the rack 79, are multiplied in the travel of the carriage. 1f the machine is operated by turning the crank 9 in a clockwise direction, according to Figure 4,. the cam'77 revolves in the di- 11d rection of the arrow. By noticing the form of cam 77, it will be seen that cam arm 75 has moved the carriage to its extreme forward position in which the forward fixed stop 104 operates to release a groupof 1'15 checks. The carriage is then returned to its rearmost position shown in Figure 7 to, receive another group of checks. The cam arm is next moved into aiposition intermediate to its extreme forward and rear I positions, thus bringing the carriage forward to a position in which the movable intermediate stop 105 operates the grippers to release asecond group of checks in the rear of the firstv mentioned group. AS125 shown in Figure 6, a' cam lever 151 which is .fulcrumed at 152, is operated by cam 45,

saidcam lever being rovided with a finger or dog153 whichisa apted to lock the endless chains or belts; 124 during those pemods gae of documents,

in which the checks are being positioned. As soon as the checks are thus arranged in order, the endless chains or belts are released so as to permit them being moved into position under the multiple writing instrumentalities. According to the present embodiment of my invention, this operation is preferably performed by a secon operator who turns the crank 132. A further movement of said endless chains or belts 124, after the checks have adapted to discharge said checks into the several compartments of the packing box wherein they are arranged in the same order in which they were withdrawn from the feed table l-(l.
