ATTACHMENT FOR BOOKKEEPING Joseph H. Loeb, Morgan City, Application December 16, use, seriai'na' 641,03: s (oi. ie'iz'i-i carriage which permits the posting of a customer's statement, led e? and prootjournal, and other 7 items. In such-machines a 'platen'is employed which theloose-leaf ledger paper is placed it) sits; having beentaken fronfthe books for the posting of the various items. In such machines,

- however, it is diiiicult without the exercise of great are to place the'paper inposition so that other items may be added in sequenceto the last posted it on the sheet. Various ineanshave been employed for this result but such means are still dependent upon the skill of the operator rather than upon any :mechanical means embodied in the machine.

' ,It is an object of the present invention to'pro- ,vide an attachment for bookkeeping machines which will automatically position the sheet'in a bookkeeping machine forthe application of additional items after the sheet had been previously A further object of the invention is the provision of an attachment for bookkeeping. machines in which the usual'operating lever for the plat'enwill automatically punch holes in the side of the sheet so that a plunger or stop will engage the opening thus formed and not only provide for a line for line positioning of the sheet but will 4/ determine the exact position. of a sheet when new items are to be applied thereto. K

This invention will be best understood from a consideration of the following detailed description, in view ofthe accompanyin drawingsforming a' part of the specification; nevertheless, it is to'be'ju'nderstood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the' invention as expressed in the appended claims.

Referring more particularly tothe' drawings, 10. designates a frame which forms part of the bookkeeping machine and is adaptedrto support elements which also form .part of the bookk'ingmachine.

A platen 11 is connected to a shaft 12 and this shaft is connected to a stub shaft 13 by means of a clutch member which will be described presently." A shaft 56 is provided with a manipulating member-13 for manually rotating the platen 11 for properly positioning a sheet of paper.

A gear 16 is loosely mounted upon astub shaft 1'1 carried in bearims 18 on the frame 10.

A bell crank lever, generally designated by the numeral 20, has an operating arm 21provided with a manipulating handle 19 which is manually actuated. A short arm 22 forms part of the bell crank lever. This bell crank lever is loosely mounted on the shaft 17. The upper end of the arm 21 is provided with a sleeve 23 in which is ,slidably mounted an arm 24. A spring 25 on'the arm 24 retains the arm 24 in apredetermined position. A pawl26 on the outer end ,of the arm 24 is adapted to engage, the teeth of the gear 18,

- A spring 2'! is connected between the outer free end a the arm 21 and a fixed part 28 of the'book- Figure 8 is an enlarged fragmentaryvertical' keeping machine so that the spring will always tend to move the arm 21 to the position shown in Fig. 2. Aspring 29 maintains the pawl 26 in position for engagement with the teeth of the gear The short arm 22 is provided with a depending rod 30 which carries at its lower free end a hinged pawl 31 adapted to engage a crank 32 formed integrally with a shaft 33 mounted in a bearing 34. A second crank 35' carried by the shaft 33 is adapted to engage an enlarged free end 36 of a rod 37 slidably mounted in bearings 38 on a base member 39. Y

An arm 40 projects laterally from, the .rod .37 and is provided with a pin 41 adapted to be received within a perforation 42 previously formed ina sheet of paper 43 which is adapted to be moved by a platen 44. The pin 41 is provided with a ball 45. at its lower end which is capable of beingrevolved when sliding over the surface A sleeve 46 is received by a reduced endof the platen 44 so that the outer surface of the sleeve is flush with the outer surface of the platen. This sleeve is held stationary against rotation while the, platen 44 is rotated. This sleeve is provided with a perforation 47 which receives the pin ,41 when the perforation and cut-out portion 42 align with the perforation 47, thereby maintaining the sheet of paper against movement.

A'- spring 48 is connected with the arm 40 and wi the fixed part 49 and is adapted to maintain the 41 in engagement with the sheet 43 whfii items are typed on the sheet.

The arm 24 isslidably mounted in the sleeve 23 and this sleeve is pivotally connected to the arm 21, as shown at 50, sothat the arm 24 may not only be reciprocated but may be rocked by the spring 29 for moving the pawl 26 into engagement with the teeth of the'gear 16.

The outer end of the arm 24 is sheared oil at an angle, as shown at ,51, and is adapted to engage a cam member 52 on the bracket 28 so that when the sheared-oil portion 51 engages {the cam 52 -it will elevate the arm 24 and move the pawl 26 out of engagement with the teeth 16.

A gear 55 is secured to a shaft 56 and this shaft is connected at one end with a clutch member 57 while the other end of the shaft has a manipulating knob 131: secured thereto for'manually rotating the shaft and the platen 44.

A second clutch member 59 is secured to a shaft 12 and this shaft is connected to the platen 44. A spring 61 maintains the clutch members 57 and 59 in operative relation but will permit slidinghnovementof the clutch members for a purpose which will be presently explained.

The sleeve 46 is provided with a,lug 62 which is hinged at 63 on the sleeve so that the lug may maintain its vertical position in one direction of movement ofthe platen 44 but which may be moved on its pivot when the platen is shifted in the opposite direction.

shown more particularly in Figs. 7 and 8. This lever is provided with a cam member 67 which is adapted to be engaged by the hinged lug 62 when the platen is moved automatically by the typewriting apparatus to the left, as shown by the arrow in Fig. 6, thereby causing one end of the lever 65-to be depressed and consequently elevating the-punch 64 so that it will produce a per-. foration in the paper 43. The position of the platen when the paper is punched is shown in dotted lines in Figure 7.

The operation of the. device shown in Figs. 1 to 9, inclusive, is as follows: The sheet of paper is placed in the bookkeepingmachine, as shown in Fig. 2, with the lower end of the sheet being inserted. The lever 21 is then moved to the right, as shown in Fig. 2, and as indicated by the arrow,

and this movement will cause a slight depression of the spring 25 and movement of the arm 24 in the same direction. The arm 30, however, moves in the opposite direction and the pivoted lugs 31 engage a crank 32, causing said crank to'be rocked whereby the crank 35 will engage the enlargemeat 36 on the rod 37 and shift it to the right, causing'the pins 41 to be moved away from the paper 43 and out of the perforations 42 inthe paper and the perforation or opening 47 in the sleeve 46 if the pin has been received by the aligned perforations. It will be appreciated, however, that when the paper is inserted in a downward manner, that the pins 41 have not been received by a perforation due to the fact that these perforations are always located adjacent the last line on which an item has been placed by the typewriting machine. when the sheared off portion 51 of the arm 24 has moved away from the cam 52, the spring 29 will pull the arm 24 toward the gear 16 so that the pawl 26 will engage the teeth of the gear so that further movement of the arm 2 will cause rotation of the gear and likewise the platen 44, due to the meshing of the

gears

16 and 55. At this time, the pawl 31 has moved away from ithe crank 32 thereby releasing the rod 37 and permitting the spring .48 to shift the arm to the left in Fig/a2 so that the pin 41 will I again come in contact with the sheet 43.

If the perforation 42 in the sheet 43 has not registered with the passage or perforation 47 in the 'sleeve 46, it willagain benecessary to rock the lever to the right in Fig. 2 as previously until the perforations are alined and the pin will slip into said perforations and retain the cylinder and sheet against further movement. If however, the perforations are alined and the pin has been received by said alined perforation during the movement of the lever 21 and the rotation of the

gears

16 and 55 the paper will not be torn due to the fact that the clutch members 57 and 59 which are frictionally engaged are permitted to slip on each other and thus prevent further rotation of the platen 44. a

Each time the arm-21 is released the spring 27 will return the arm to its normal inoperative position so that the arm 24 will ride over the cam 52 and have its pawl 26released from the gear 16. Upon return movement of the arm 21, the hinged lug 31 on the arm 30 will ride over the crank 32 and.thus the rod 37 will be maintained stafrom the machine after all of the items have been placed on the sheet, the platen 44 through the usual typewriting mechanism, or manually, is moved to the end of the line so that the hingedlug rock said ,lever whereby the punch 64' will :be" moved upwardly and towards thesheet of paper and platen until thepunch moves through a per- 6 foration 64a in the sleeve 46, thereby providing the curved surface 73a or cylinder 46.

It will beseen-by this construction that the device positively rotates the sheet of paper so that items may .be typed on the next line without necessitating the operator to attempt to determine the proper position of the paper for the application of the items. a A modified formlof the c nstruction is'shown' in Figs. 11 to 16, inclusive. In'this instance. the lever 21a is loosely mounted upon the shaft 17 so that the pawl I the medium of the lever 21.

The short arm 22a of the lever extends from the bell crank 20a and depending from the short arm 22a is a rod '10 pivotally free end of the arm 22a. The rod 70 is provided with a fork 70a adapted I iecting in opposite directions from the lever '13;

The lever 73 is pivotally mounted at '14, adjacent one end, on a bracket .75 secured to the in- The lever at this point is curved and is provided with a slot 76 through which is adapted to project a stop or pin '17.

A sleeve 78 24 and the rocking of the is supported at '19 on a bracket 80 secured to the inner face of the sleeve 46. A sp 81 tends to force the pin '17 outwardly of the e '78 and through an opening 82 formed in the sleeve or cylinder 46.

The pin 7'? is located in the slot 76 at one end of the lever '13 andlugsgmton the pin '77 rest upon 0 73 passes through 'a slot 64 formed in the sleeve of the device shown in Figs. 11 to 18, inclusive, have not been described since they are identical with the similarly located elements of Figs. 2 to 10, inclusive.

, when the lever-21a is reciprocated to the right in Fig. 12, the arm 24 'moves of! the cam member 52 so that the pawl 26 will engage'the teeth of the gear 16. Further movement of the lever will cause rotation of the gear 16 and likewise the gear 55 with a consequent rotation of the platen 44. Before the gear 16 is rotated, however, the

in the cylinder 46 and the'opening 91 formed in the sheet of paper 92 which had been previously out by-a punch 93 mounted on one end of the lever 65.

It will be noted that the sheet of paper 92 being punched with the-round perfoas shown in the sheet of paper 43 (Fig. 94 are cut from the sheet lines in F18. 18; Thus right angles to The remaininfl Parts rations 42 92.as shown by dotted the punch 93 has two blades at 1,oss,17e 62will engage the cam 67 on'the lever and 26 will rotate the gear 16 through mounted at '11 on the to receive pins; '12 pro e lever '13. The lever Since the barrel or sleeve '16 is pivotaliy mounted at 79 on the bracket 60, this barrel is adapted to oscillate so that when the lever {I3 is raised the pins '83 which project from opposite sides of the pin or stop I! will move down over the rounded portion'liia of the lever 73' to permit the stop 77, to move outwardly'of the opening--92 andmaintain the stop in operative position. I

.Jihe upper end of the barrel '16 is provided with a pawl 96 which is adapted to normally en-- gage the teeth 9'! of a to the shaft 12 conn wheel as is eeiirea ted withthe platen 44.

This maintains the platen stationary when the -pin or stop 'l'lhas projected through the opening 62- of the sleeve 46 and the opening; in the paper 92 to prevent tearing of the-paper when the lever 21a is moved, tendingic rotate the gear 16. The clutch members 59 and 57 permitslippage so that the platen 44 may be held stationary when the gear 16 is rotated.

In this constmction, asin previous constructions, the lever 21a is permitted tomove through an angle so that the lever l3 may be permitted to release the pin '1'! from the alined passages lsigfore the gear 16 is revolved to operate thegea'r The knob 13:: is employed for originally positioning the sheets of paper within the bookkeepin: machine.

In Figs. 2 to 10, inclusive, it will be seen that the paper is inserted from the front portion of the platen 44 while in the construction shown in the remaining figures it is adapted to be inserted from the rear of the platen.

When the lever ,13 is oscillated as previously described, the inner free end will bear against the lower portion of the barrel [8 and since this barrel is tilted at an angle inwardly' towards the slot '16 of the lever '13, said lever will be rocked at a greater angle, causing the pawl 9 to become disengaged from-the teeth of the toothed wheel 98 which is secured to the platen 44, thereby permitting the platen to be rotated in the usual manner.

Referring more particularly to Figs. 1 to 9, inelusive, it will be seen/that the end of the platen which is enclosed ed with a groove 100 and upon'opposite sides of this groove are secured to the platen toothed wheels 101 which are adapted to be engaged by lugs 102 shown more particularly in Figs. 8 and 9 formed integrally with the pin 41 sothat when the lugs 102 engage the teeth of these wheels the platen will be held against rotation and the clutch,

members 5': will permit the platen to be held stationary while the gear 16 is rotated through'the lever 21. This element, like the pawl 96 inFigs. 11 to 17, inclusive, retains the platen against rotation and thus prevents tearing the paper after the pins have engaged the respective cutout portions in the paper.

The barrel 78 is provided which the pins 83 ride.
