EATER-FEEDING ATTACHMENT FOR ACCOUNTING AND RECORDING MACHINES.

Specification of Letters'Patent.

Application filed January 13, 1916. Serial No. 71,863.

To all whom it may concern:

Be it known that 1, JOHN citizen. of the United States of America, and

a resident of Vvilmette, county of Cook, and

' State of Illinois, have invented certain new and useful Improvements in Paper-Feeding Accounting and Record ing Machines, of which thefollowing is a specification.

This invention relates to a device com prising paper magazine and mechanism for successively feeding slips of paper into and out of printing position, said mechanism automatically becoming operative upon the completion of some predetermined series of entries in the machine. For example, the feeding mechanism is arranged to be set in operation by the depression of a key which records the fact that the machine is clear at the time of depression of this key and the key cooperates with the accounting mechanism in a manner to prevent the depression of the key except when the accounting mechanism is at the zero position. The depressihle key also has connections for clutching the driving mechanism of the paper feeding device with a motor shaft.

The main object of this invent-ion is to provide paper feeding mechanism for accounting machines which is automatically operative to feed paper into and out of the'machine only after an accounting operation is properly entered in the machine and recorded on the paper being fed through the machine. Further objects of the invention are to provide an improved means for stacking paper slips such. as bills or checks in the paper magazine so that the desired friction is maintained between the particular slip which is to be fed and the feed roller and at the same time provide a minimum of friction between the said slip and the remaining slips in order that a plurality of the slips shall not be dragged and fed through the machine at the same time.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figure 1 shows in side elevation the 'improved paper feeding mechanism and some of the cooperating parts of a typewriter and the accounting machine.

and the typewriting machine, v'ith which the device, as shown in the ings, may be combined.

In the drawings the motor 1 is shown having a beveled gear connection 2 with a The latter carries fast a ratchet wheel 4 adapted to coiiperate with a pawl 5 pivotally' mounted on disk 6, can nied fast by a sleeve 7 journaled in frame El and carrying fast at its upper end a helical cam 9. Pawl 5 is normally held-out of engagement with ratchet wheel 4: by a cam arm pivotally mounted on 2. lug ll of frame 8 (see Fig. 1). The shattil may there forcrotate independently of cam 9 but hey controlled means are provided for with drawing cam arm 10 from pawl 5, permitting the latter to engage the ratchet wheel at. The cam f) in this manner becomes clutched to shaft 3. For the purpose of unclntching the cam 9 from drive shaft 3, cam arm 10 is provided with an inclined flange 12 for engagement with a downwardly extending pin 13 on pawl At the end of each open ation of the machine, pin 13 engages the flange 12 when the cam 9 has completed its work of operating the paper feeding mechlllllSln.

present drawgagement by a spring 14.

The cam arm 10 rocked to release pawl. Fig. 1, this losing" the specific means shown in the drawings for setting: the paper feeding mechanism into operation. The shank 16 of this key Patented Feb. 20, 1917.

When the pawl is permitted to en gage ratchet wheel 4 it is rocked into encarries a pin 17 passing through a slot 18 in a lever 19.1 pivoted to the machine frame at 20.1 Lever 19.1 is connected a link 19.2 to a key lever 19 pivoted to the machine -frame by pin 20. By this arrangement, movement is imparted to key lever 19, either by depressing said, lever at its head 15.1 .or key 15, this lever being one of the usual keys of the typewriter and having connections for operating type bar 36.

' Lever 19 carries pin 21 passing through a slot 22 in one arm of a bell crank lever 23 pivoted to the'frame of the machine by a pin 24. The upwardly extending arm of .bell crank lever 23 carries a clip 25 connected by a rod 26 to an arm 27 rigid with cam arm 10'on ashort shaft 28 journaled in the lug 11. Key 15 is also shown as controlling means for closing the motor circuit 29. Fig. 1 shows in diagram a motor circuit terminating in a pair of contacts 30 which may be electrically connected by contact 30.1 carried at the bottom of key 15. Key 15, cam arm 1'0 and the connections between the two may be restored to normal position at the desired time by a driven oscillating shaft 31 which carries a pin 32 cooperating witha cutaway hub 33 on an arm 34 journaled on shaft 31. Arm 34 is connected by a link 35 with lever 19.1. Normally the key 15 may be depressed without changing the angular setting of shaft 31, but connections (not shown) are provided between shaft 31 and the motor for first rocking shaft to the right and then returning it to its normal position, I as shown. The right'hand rocking of shaft 31 results in the engagement of pin 32 with the shoulder on hub 33, returning arm 34 and through it key 15 and cam arm 10 to normal position. The restoring movement occurs before cam 9 has made a complete rotation and accordingly, as arm 10 is in its upper position, at the end of each rotation of the cam 9, pawl 5 is disengaged from ratchet wheel 4.

Bell crank lever 23 is connected to actuate a printing hammer 36 upon the depression of key 15. This hammer cooperates with a platen 37 around which the paper is fed by the action of cam 9 and carries a special character for making a record that the machine is clear at the time of the depression of key 15; that is, at such time, the'indieating or accounting mechanism 38 is in its zero position. To prevent the t'lepression of key 15 or 15.1 when the accounting device is set at some other position than zero, said device is provided with a plurality of notched disks 39, all cooperating with a roller 40 carried by a bell crank lever or frame 41 pivotally supported in the machine frame, and adapted normally to hold the bell crank 41 in engagement with a lug 42 carried by the key. It will be understood that there is provided one disk 39 rigid with each number wheel of 4 the accounting device. l Vhen all the number wheels of the accounting device are in zero position bell crank lever 41 may rock out of the path of movement of lug 42 as the roller 40 may rest in the notches in disks 39. The actuating device for the accountin mechanism and the keys for controlling its differential movement are omitted from the drawings as their specific construction forms no part of the present invention. 7 The paper feeding device comprises platen 37. feed rollers 43 and 44, coiiperating paper guides 45, 4G and 47. a'paper magazine 48, and. a delivery platform 49. The cam 9 cooperates with a roller journaled in a bar 51 slidably mounted in a s t 8.1 in frame 8 and adjustably connected with a link 52 by means of a set screw 51.1. The bar 51 and link 52 are further guided in their vertical movement by downwardly projecting 5 parts 52.1 of.link 52 overhanging the edge of cam 9, as shown in Fig. 5. The link 52 is pivotally connected at its upper end with a bar 53 carried by a pair of arms 54 journaled on a shaft 55 supported in the frame 56 of the paper feeding device. One of the arms 54 terminates in a gear sector 57 meshing with a pinion 58 fast to a sleeve 59 rotatably mounted 011 ashort shaft (30 (Fig.

The sleeve 59 also carries fast an arm 95 61 upon which is pivoted a pawl 62 normally held by the pressure of a spring 63 in engagement with a ratchet v eel 64 rigid with a gear wheel'65 journaled 011 sleeve 59. Gear wheel 65 meshes with a pinion 67 oo on feed roller 43. .By means of the pawl and ratchet connection described, the oscillation of sector gear 57 imparted to it by the rotation of cam 9 resultsin the forward rotation of feed roller 43 the desired number of degrees to feed the lowermost slipof paper on magazine 43 far enough so that on. the second operation of cam 9 the paper will be fed dmvnwardly around. platen 37 into printing position and the second sheet of paper will be fed into position so that'on the third operation of cam 9 the second sheet will be in place to receive a record. The feed roller shaft 68. to which pinion 67 is secured, carries at its opposite end a pinion 69 which through a pair of intermediate gears 70 and 71 transmits the rotation to platen 37 and feed roller 44. Gear 71 meshes with a pinion 72 loose on, the platen supporting shaft 73 but rigid with a ratchet wheel 74 adapted to coiiperate with spring pressed pawls 75 pivotally mounted on a disk 76 secured to'platen 37. This arrangement permits the platen to be manually rotated in a forward direction independently of its driving mechanism. The platen may also be freely rotated in 'a backward direction for the convenience of the operator because pawl 62 when in its normal position is held out of engagement with ratchet wheel 64 bye. 1 30 pin 77 stationary in the frame 56. The platen shaft as usual carries a knurled head 78 by which it may be rotated manually. l

From the foregoing description it may be seen that two depressions of key 15 are necessary before the bottommost slip of paper on magazine 48 is fed to position to receive an impression. After the firstslip receives its impression a single depression of ke 15 is sufficient to feed the slip printed upon to platform 49 and a. new slip into position to receive an impression. Separate means are, however, provided for manually adjusting the first slip to printing position by a single operation. This means includes a ratchet wheel 7!) rigid on shaft 80 to which the intermediate gear is secured. .\n arm 81 is journaled on shaft 80 and carries a. pair of pawls 82 for cooperating with ratchet 79. The pawls are spring pressed into engagement with ratchet but are normally held out of engagement by a pair of fixed stops 83. The manually operative feed device accordingly does not interfere with the normal rotation of shaft under the action of cam 9, but when arm 81 is drawn forward by its handle 81, the pawls 82 pass over stops 83 and engage ratchet wheel 70, rotating it far enough to feed the first slip from magazine 48 around the platen 37 into position to receive an impression. When arm 81 is released it is restored to its normal position by a spiral spring 85. Arm 81 is limited in its 1nove-' ment by a lug 86 on a member 88 which may be adjusted and locked in various positiOns by a screw 89 in casing 87, for the purpose of regulating the throw of arm 81' and the consequent extent of feed of the paper. The manually operative means for operating the paper feeding device is not essential to the machine. butis provided for the convenience of the operator and affords an adjustable means for effecting multiple line spacing in a (litter-cut aml more convenient manner than that which is regularly provided for in the general mechanism of typewriters and accounting machines of the general class to which the present improvements are applicable.

The desired degree of frictional contact between the supply paper and feed roller 43 is brought about by mechanism now to be described. The. supply magazine 48 is provided with a pressure rod 90 carried by a pair of arms 91 pivoted on a rod 92 carried by frame 56.. The frame comprising arms 91 and rod 90 is normally urged to rock downwardly by springs 93. but as the rod 90 rests in notches 94 of the removable frame 95, the action of the springs is transferred to frame 95. on a flat board 96. The board 96 is adapted to bear downwardly on a stack of supply paper between it and the base 97 of maga- The latter is mounted zine 48 and normal sets at an angle to base 97, as shown in ig. 1, in order to provide the desired pressure between the stack of paper and the feed roller 43 while permitting only a minimum between" the individual leaves of the paper throughout the greater part of their area. This arrangement permits thelowbrmost sheet of paper to be carried freely away from the remainmg paper of the stack and insures, that only one sheet at a time chine. The sheets of uper, however, are permitted to overlapshghtly at their front and rear edges while passing around the platen. The arrangement of the gearing in the paper feed mechanism is preferably such that the platen rotates'at slower speed than the feed rollers 43 and 44. his results in the paper buckling slightly between the roller 43 and the platen thus urging its for ward edge to aline itself along the point of contact between the idle pressure rollers 98 and the platen. When the rear edge of an individual sheet of paper passes away from feed roller 43, the platen controls its move ment through the machine until thesheet of paper is picked up by feed rollers 44. when its speed is increased. The printed sheets of paper are finally stacked on platform 49.

travels through the madrawings but it may be understood that when there is ,a. stack of paper on platform 97 the forward edge of the stack is in contact with the guide plate 99 and that rod 90 is in its upper position and the springs 93 extended, the board 96 resting on the top of the stack bearing downward on it to afford the desired pressure between the paper and feed roller 43.

In the operation of the device, the bills, checks, blankaper or whatever is to receive the impressions are stacked on platform 97 beneath the spring pressed board 96. The'first sheet may be placed in position around the platen to receive an impression by drawing arm 91 forward, in this manner actuating the feed rollers the desired extent. The same adjustment of the first sheet of paper may be effected by twice depressing key 15. After the paper is written upon, including a record of the accounting operation which is effected in the machine. the key 15 is depressed, setting the motor in operation and rocking cam arm 10 away from pawl 5, permitting it to clutch the cam carrying shaft 7 with the driven shaft 3. The cam is then given a single rotation by the action of the motor, forcing the member 52 upwardly and through gear sector 57, actuating feed rollers and platen 37 to carry the printed sheet of paper out of the machine, depositing it on the 'receivin platform 49 while causing a second eet tocome into position to receive an impression.

After roller 50 clears the highest point of cam 9 it returns by gravity or a spring to its normal position as shown in Fig; 1. Previous to the completion of the rotation of cam 9 the cam arm 10 is restored to its normal position by the action of the oscillating shaft 31. At the same time key is restored and the motor circuit opened. In the drawings the key 15 is shown as Controlling the motor circuit by way of example merely.

Nith the present clutch arrangement between shafts 3 and 7 the motor of course may be controlled by separate means and in fact permitted to rotate continuously between feeding operations. It may be seen that it is impossible to effect a feeding operation or close the motor circuit except when the accounting device 88 is in its nor.- mal position, as in other positions the arm 41 prevents depression. of key 15. Fromthe foregoing it may be seen that the feeding mechanism and in fact the motor ing the machine, is dependent for operativity upon the condition of setting of the accounting mechanism. The paper receiving a record remains in printing position until the particular accounting operation recorded thereon is completed.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numererativity on the setting of said accounting device.
