TYPEWRITING MACHINE.

Application :ned september 1e, 1925.

This invention relates to tally-sheet feeding devices for typewriting machines, and may be advantageously used in grocery and other stores for making a tally of the orders to be delivered by each driver. The device may be mounted at one end of a typewriter platen, so as to leave the other end free for typing thereon the usual customer sales slipsl at the same time a tally of them is made; the sales slips and the tally-sheets being linespaced and typed independently of each other.

Provision is made in the present invention of a feed-'roll supporting frame mounted above the right end of the platen of a typewriting machine on a sleeve .over a stiff rod, the latter being held at 1ts two ends in brackets mounted on the carriage side frames. A stationary rotatable feedroll is mounted in said frame above said platen and not engaging the same. A swinging feed-roll is mounted for engagement against the top of the stationary feed-roll in the ends of two arms pivoted to said frame. A star-wheel is mounted on the shaft of the stationary feed-roll, and upon depression of the usual feed-roll-release lever, is rotated by engagement with a pawlmember which is pivotally fastened to the lower end of the usual link-member attached to the rear end of said lever. The usual feed-rolls are omitted under the right end o'f the platen, and a tally-sheet around this end engaged between said upper feedr'olls may be line-spaced upon movement of said star-wheel without revolving the platen. To permit characters to be typed near the top edge of the' tally-sheet, a roll is inounted in the ends of two arms pivoted to said feedroll frame, and is arranged to hold the sheet a ainst the platen a short' distance above t 'e printing line. This roll may be swung upwardly out of the way when not kin use.

Other features and advantages will hereinafter appear.

invention in place on the carriage of an Underwood typewriting machine shown partly in section. The front tally-sheet holding roll is fhown in its upper position.

Figure 5 is a fragmentary plan View of the right-hand portion of the carriage in an Underwood typewriting machine with the tally-sheet feeding device in place.

A platen may be mounted on shaft 11, journale'cl in a carriage side frame 12 of an Underwood typewriting machine. A paper table 13 having an apron extension 14 is arranged between the said frames. Feed-rolls 15 and 16 are mounted only under the left-hand portion of the platen l0 on the usual feed-roll rods, not shown. The feedrolls may be thrown against and away from the platen by manipulation of a feed-roll release lever 17 which carries a link 18 at I its rear end, the latter being connected with an arm 19 on a cam shaft 20, which is arranged to move locking arms, not shown, which arms support the ,feed-rolls 15 and 16.

For mounting' thev tally-sheet feeding device,

brackets

21 and 22 may be fastened on the rizht and left side frames l2 and hold Secu're y between them a stiff rod 23 over which ma` be slipped a sleeve 24: to whose ends may ne' s eci'ue'ly' fastened two plates 25,

by riveting. The sleeve 24 will be of proper length to d,permit the right-hand plate 25 to be positioned adjacent the right-hand end of the platen 10 and have the left-hand plate 2:5/ come a short distance beyond the left.

edge of atally-sheet 26, used in the device. A roll 27 engaging against the platen 10 forv a purpose hereinafter exlained, is mounted en a shaft 27"il held in tie forward ends of two arms v28 and 28El which have upwardly curved portions 29 and are fastened on the outer ends of a rod 30, the latte'r being' journaled in the plates 25 and eX- tending outwardly therefrom a short distance. A stationary feed-roll 31 is mounted a short distance above and not in engagement with the platen on a shaft 32 journaled in the left-hand plate 25 and in a floating bearing plate 33 attachedto the right-hand plate 25 and in the bracket 21. A swinging feedroll 34' is mounted for engagement with feed-roll 31 in the forward ends of two arms 35, which may be pivot-ally mounted on shouldered screws 36 threaded into the plates 25. Upwardly turnedA rar ends 37 e? e5 may be here in.

loix

substantial right angles, and be connected by a bar 38 to form a. swinging bail. vTo limit the upward swing of the feed-roll 34 (see Figure 3), two pins 39 are fastened in the plates in the rear slightly below screws 36.

A star-wheel having four points 41 and four cavities 42 may be fastened on the shaft 32, adjacent the inner side of the bracket 21. A short inwardly and laterally projecting pin 43 may be fastened securely in veach point 41. The tally-sheet 26 passes between the feed-

rolls

31 and 34 and may be linespaced by depressing the feed-roll release lever 17. This action raises the link 18, which carries in its lower end a stud 44 to which is fastened a space-pawl 45, having its upper` end arranged with an L-shaped concave cavity 46 for engaging under the pins 43, one at a time. The Apawl may rotate through one-fourth of a revolution a starwheel '40 and a feed-roll 31. By providing a feed-roll of the proper size the tally-sheet 26 may be advanced one or more line-spaces on the platen 10 for each depression of the lever 17. When the lever 17 is returned to normal position, the pawl 45 is lowered and th-e cavity 46 Ais pulled into engagement under the next lower pin 43 by action of a spring 47 which has one end fastened to the pawl 45, and the other to al downwardly pro jecting arm 48.. ofthe bracket 21. A roller 49 mounted on the forward end of ay detent lever 50 for yieldingengagement inthe c avities v42 prevents 'the' star-wheel Afrom being rotated backwardly when the pawl is being lowered, and also properly' lines'up the'lfeedroll 31 when' the latter .is moved'forward a slight amount too'muchl or too little upon depression fof the lever 17. AThe roller 49 vis always held in 'engagement with the` Starwheel 40 byaction of a tensile spring 51 yfastened to 'the rear end of the lever 5K0 and to the bra-@kaar In one vuse 4of the tally-sheet vfeeding device, to make a recordlof groceries delivered `by .a driver, a narrowJ sales-slip 60, such as is commonly yusedin grocery stores, may be inserted from the reararound the lefthand portion 'of the platen A10 between the latter and the usual typewriter lfeed-'rolls 15 and 16,. The tally-sheet26 may be pushed under the platenfro'm the rear until'its front end has passed the forward end of the apron 14. The sheet may then be seized and pulled up around the platenuntil'it can be gripped against the latter by the feed-roll 27, as illustrated in'Figures 21and13. The upward bend 2,9 in the right-hand arm 28 prevents the arm froml striking the shaft -32 when the roll 27 engages against'the platen. This use of the roll -2 7 permits a heading or other data tofbe typed on the tally-sheet near its top edge. After the heading has been typed, the roll 27 may De swung upwardly to the position shown in Figure 4 where it will be held against pins 61 by the pull of springs 62, the same that hold the roll against the platen. This desirable result is obtained by fastening one end of each spring to a pin 63 in one of thevarm's 28, and fastening the other end of the spring to a pin 64 in the plate 25, which pins are positioned so that the springs 62 are moved across the line of the axis 30 when the roll 27 is raised from its lower to its upper position. A light downward pressure of the bar 38 will raise the feed-roll 34 against the pull of a spring 65 and permit the tally-sheet 26 to be easily inserted between the feed-

rolls

31 and 34. Several items maybe typed on the sales-slip 60 in the usual way and the platen 10 line-spaced after typing each item, without adecting the tallysheet 26, since there are no feed-rolls holdin the sheet againstthe platen. items have been typed on the sales-slip, the carriage may be moved to the left and the customers name with the total of his purchase and any other desired memoranda may be typed on the tally-sheet 26. When more than one line of data is typed on the tallysheet, the lattery may be line-spaced by manipulation of the lever 17 without affecting the sales-slip 60, since the platen 10 is not. moved by rotation ofthe feed-

rolls

31 and 34. The sales-.slipmay be removed and another one inserted, without disturbing the tally-sheet 26. It .can be readily seen that, if desired, carbonY copies can be made of v*either or both thev sales-,slip 60 and the tallysheet 26. f

Variations may b e resorted to within the scope of theA invention, and portions of the improvementsmay be used without others.

Having thus described myr invention, I claim: y
