Patented `Fan. 5, 1932 UNITED STATES PATENT OFFICE RALPH E. PAGE, F BINGHAMTON, NEW ASSIGNOR T0 THE TABULATING MA- CHINE COMPANY, OF ENDICOTT, NEW YORK, .A CORPORATION 0F NEW JERSEY QUICK Parma INSEMING DEVICE Application led September 16, 1926. Serial No. 135,792.

This invention relates to accounting machines and more particularly to a paper inserting device to be used in conjunction therewith.

In machines of the above type considerable time is wastedV in positioning the paper with regards to the margin desired at the top, whereas in my device this operation is done simultaneously with the paper inserting operation.

An object of my invention is to improve generally an apparatus of this kind.

Another object is to provide economic and efficient means for inserting paper under the platen roll.

Another object is to provide convenient means so that substantially any part of the paper may be brought into relation with the platen roll.

A further object is to eliminate the adjusting of the paper after it has been inserted under the platen roll.

A still further object is to provide a storage roll whereby the data printed on a sheet of paper may belwound simultaneously with the printing operation.

Other ob'ects and advantages of my invention wil be set forth in the following description and drawings in which:V 80 Fig. 1 is a side elevation of my device according to the invention;

Fig. 2 is a detail view of the paper feeding mechanism shown in Fig. 1;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a. sectional View showing the coil spring and governor for returning the rack to normal position;

Fig. 5 is a. sectional view taken on line 5 5 of Fig.l 1.

Referring more particularly to the drawings, Fig. 1 comprises a frame 1 attached to an accounting machine or the like in the usual manner so that the platen roll will be in position to cooperate with the type.

Mounted in said frame is av platen roll 2, Fig. 3, revolved by means of shaft 3 rotat ably supported on frame 1. A dispensing roll 4 is provided for feeding paper-5 onto platen roll 2. Rigidly aiiixed to dispensing roll 4 at each end is a shaft 6 which revolves in frame 1. At theuppermost end of frame 1 is another roll 7 acting as a storage or receiving roll. Storage roll 7 'is revolved by means of shaft 8 and supporting center 8a. A shaft 15 is provided at the left side and has slidably mounted thereon a supporting vcenter 16 which is actuated by spring 17 into engagement with roll 7. By pressing supportlng center 16 against coil spring 17 said storage roll 7 may be easily removed. Shaft 8 revolves in frame l and boss 9 and has mounted thereon at 10 a friction driving ring (see Figs. 1 and 3) which friction driving ring has aiixed thereto a pulley 11. Friction driving ring 10 is comprised of two portions 10a and 10b hinged at 10c closed upon shaft 8 byymeans of spring 19. Frio tion driving ring 10 and pulley gear `11 are freely mounted on shaft 8. By means of a n nut or washer 12 fastened to the end of shaft 8, pulley 11 is held in position. Fixed onto shaft 3 at 13 is another pulley which upon rotation of platen roll 2 causes .pulle 11 to be rotated through the medium of a lt 14. Pulley 13 is larger than pulley 11`in order that the roll 7 shall turn more rapidly than the platen and thus hold the paper tightly Wound thereon. As the paper 5 accumulates on the storage roll 7 it is obvious that as the roll becomes larger rotation of same will become slower although belt drive 14 continues to run at the same speed. Friction driving ring 10 will slip upon shaft 8 thereby causing roll 7 to revolve at a much slower speed than that of driving belt 14.

Referring to Figs. 1 and, 2, ri 'dly affixed to disc 21 is a spur gear 2O both eing freely supported upon shaft 3. Gear 20 meshes with the teeth 44 of rack 27. Pivoted to disc 21 at 22 is an actuating pawl 23 biased by spring 24 to cause engagement of said pawl with ratchet wheel 25. Ratchet wheel 25 is rigidly affixed to star gear 26 which staf!` gear is firmly mounted o'n shaft 3. When rack 27 is pulled to forward position, pawl 23 actuated by spring 24 cooperates with-ratchet Wheel 25 and causes rotation of platen roll 2. Rack 27 has fixed thereon extending horizontally on the inside of samea channel b ar which holds said rack in place by means of roller bearings 28 which bearings are carried by frame 1 by means of brackets 29. Extending along the top and bottom of rack 27 are teeth 44 meshing with spur gear 20 and pinion gear 30. A groove 31 is provided on the front of rack 27 to cooperate with stop 32. Stop 32 (see Fig. 5) is slidably mounted on rack 27 by means of ianges 33 reaching over the back of the rack. A tooth plate 32a fixed to the stop 32 meshes with the rack teeth 44 to prevent the stop from creeping. B

lifting and sliding stop 32 it may be moved along the teeth on the rack to any desired position.' Afterthe determined position is reached tooth plate 32a on stop 32 meshes with .the teeth 44 on the upper part of rack 27 and same is rigidly held in position by turning of set screw 34 which set screw has a wedge shape projection 35 gripping itself firmly into groove 31 on rack 27. Wedge shape projection 36 on stop 32 upon pulling of rack 27 to forward position engages itself in star gear 26 (see also Fig. 2) thereby allowing the paper inserted on the platen roll to be rotated an equivalent distance to which the stop 32 had been previously set. A handle 37 (Fig. 4) is rigidly affixed to rack 27 at 38 and provides for the pulling of said rack to forward position. As shown at 37a on the rack 27 numerals and graduations may be provided to enable the operator to deter'- mine where to set` stop 32. When rack 27 is pulled to the forward position pinion 30 mounted on shaft 39 causes a tension to be made upon coil spring indicated by dotted lines 42a in drum 42 (see Fig. 3). The coil spring automatically returns rack 27 when released to its normal position. The spring box or drum 42 is mounted on frame 1 by means of a plate 41a and screws 41. A governor indicated by dotted lines 426 may also be provided in drum 42 to prevent shock when said rack 27 is returned to its normal position. The construction and arrangement of the spring and governor are not shown in detail as any conventional construction may be employed. After rack 27 has been returned to its normal position a pin 43 firmly lfixed on rack 27 engages with the tail 23a of pawl 23 drawing same out of engagement with the ratchet 25 thereby allowing the carriage to be turned manually in either direction.
