Aug. 25, 1931. H. H. VICKERS TYPEWRITING MACHINE Filed Jan. 25, 1928 Patented Aug. 25, 1931 PATENT OFFICE UNITED STATES HARRY H. VICKERS, OE CORONA, NEW YORK, ASSIGNOR TO UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE TYPEWBITING 'MACHINE Application filed January 25, 1928. Serial No. 249,288.

The present invention relates generally to typewriting machines, and more particularly to tally-strip devices therefor.

Many business firms who have chargeaccount customers make up a new statement-sheet for each account at the end of each month and send the old statement-sheet t the customer. The new statement-sheets having the customers names and addresses printed thereon are given in alphabetical order to the operator of an Underwood typewriting-computing machine, and the proper balance is copied on each new statementsheet from its associated ledger-sheet. If

1 the total of these balances does not check with the total obtained from the usual control sheet, an error has been made and a check, i. e., a comparison, must be made to find the error., Heretofore, for making this check, the operator, immediately after copymg a balance on a new statement-sheet,

. would copy the same balance a second time on a strip of paper in an adding machine. When a check was required, the list of balances made in the adding machine was compared with the balances on the customers ledger-sheets, thus avoiding the handling of a large number of statement-sheets and also the possible soiling of some of them. It has usually been considered preferable heretofore, 1n preparing this checking list, to copy each balance a second time rather than call in a mechanic to attach a usual tally-strip device for doing work which lasted only a day or two, once a month. The chance of errors occurring, however, in preparing a checking list this way can be readily seen.

It is an object of the present invention to provide a tally-strip device for making a carbon-copy checking list of the balances typed on statement-sheets or the like, which device can be quickly, and easily attached to and removed from a typewriting-computing machine by an operator using only her hands.

In practicing my lnvcntlon, a standard.

Underwood typewriting-computing machine having a usual front collating table is employed, To be fastened to the collating table in the rear thereof, there is proward end thereof, the slot being of a width to engage with a snug fit about the-top edge portion of the collating table. The

depth of the slots is s'ufiicient to permit the,

tally-device to be self-retaining on the collating table and without danger of bending the sheet-metal body thereof.

It is a feature of the present invention to facilitate securing the tally-device positively in any one of a plurality of operative positions for co-operating with statement-sheets of varying widths by providing two rackelements in the top edge of the collating table, each notch of one rack having a paired relation with the notch in the other rack, and each pair of notches being spaced. apart for receiving the side plates of the tallystrip frame. 7

Another feature is the provision of means for quickly attaching and detaching the feed-roll from the tally-strip device.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

,Figure 2 is a fragmentary cross-sectional view, front to rear, of the machine and tallystrip device looking towards the left-hand end of Figure 1.

Figure 3 is a disassembled rear View of the tally-strip device of the present invention; certain parts being shown partly broken away to better illustrate the construction of the device.

In an Underwood combine-d computing and typewriting machine, types 10 strike against a revoluble platen 11 on a shaft 12,

which is journaled in end plates 13 of a The end plates have out-reaching horizontal flanges 15, and a rear paper-table 16 extends between the end plates 13 at the receiving side of the platen and curves upwardly around in front of the platen to terminate in an apron 17, which has cutouts for receiving lo-wer feed-rolls 18. Usual mechanism for releasing the feed-rolls includes a feed-roll-release lever 19. Usual line-spacing instrumentalities may be. provided and include a ratchet-wheel 20 fast on the shaft 12 and a pawl 21 for engaging with the ratchet-wheel teeth. An auxiliary rear paper-table 22 may be disposed slightly forward from the rear table 16 for a use to be described hereinafter. The platen-frame 14 is mounted on a carriage 23. The abovedescribed parts may be substantially the same as like parts shown and described in the patent to J. A. B. Smith, No. 1,524,756, dated February 3, 1925.

A collating table at the delivery side of the platen, generally designated as 25, may include right and left plate-metal body- sections 26 and 27, respectively, each of which has a forwardly-extending side-edge flange 28, which may serve to laterally gage a state ment-sheet 29. The sections 26 and 27 are mounted on a stiff lateral cross-bar 30, which is fastened to end plates 31 (only one of which is shown), which have lateral mounting flanges 32 resting on the flanges 15 and fastened thereto by screws 33. The sections 26 and 27 may have a usual rectangular portion cut out along their top edges extending from their inner edges outwardly.

In practicing the present invention, there is rovided a tally-strip device generally deslgnated as 40, which includes a frame 41 having right and left side plates 42, which are fastened together rigidly by instrumentalities including a cross-rod 43 which has one end fast in each of the plates. A blade 44 also extends between the side plates 42 and is fastened to each plate by screws 45,

and has a sharp edge 46 for a purpose to presently appear. The blade may be detached and sharpened by removing only one of the screws because of lengthwise slots 47 bein provided in each end portion of the blade or the screws 45 to pass through. The heads of the screws are wider than the slots 47 and are effective to bind the bar against the side plates 42.

To provide for the operator attaching the frame 41 on the table 25 and removing it therefrom quickly by her hands and without releasing any screws or other fastening 'devices, an open mounting slot 48 is cut through-the lower edge portion of each side plate at right angles to the lane thereof adjacent the forward side 0' the frame. The two slots lie in the same plane and are wide enough to engage with a snug fit over the top edge of the plate- sections 26 and 27 which are made thick enough to give them sufficient stiffness to withstand the additional strain caused by engagement of the slotted side plates.

A supply of tally-strip is provided in the present invention by wlnding a length of narrow strip 50 overlaid by carbon-strip 51 onto a spool generally designated as 52. The spool has two spool-heads 53 fast on a spindle 54, each spool-head having a beveled cone-like periphery 55 inclined upwardly and toward the center of the spool for a purpose to presently appear. The beveled peripheral surface of each spool-head may be roughened by fine milled serrations or knurls 56. The spindle 54 may have a circumferential groove 57 positioned a short distance outwardly from the outer face of each spool-head. For rotatably mounting the spool 52 on the frame 41 an open slot 58 is cut in the rear edge portion of a rearwardly-extending heel-member 59 on each side plate 42. The portions of the spindle 54 adjacent the spool-heads 53 engage in the slots 58 loosely to be revolved freely, and a detent-arm 60 is arranged with a hook-like end 61 for engaging in the adjacent groove 57 to reach partly around the reduced portion of the spindle 54. One arm 60 is fastend by a screw 62 on the end of a rockshaft 63 which passes through and is journaled in the side plates 42. The other arm may be fastened in any suitable way to the other end of the shaft 63. A washer 64 spaces each arm a slight distance away from the adjacent side frame. To urge the detent-arms normally upward against the spin- (lle 54, a spring 65 is coiled with initial tension around the shaft 63 and has a straight end portion which extends rearwardly to bear on the cross-rod 43, the other end of the spring being fastened around a screw 67 which fastens a collar 68 on the shaft 63 against the adjacent side plate 42.

The tally-strip 50 and carbon-sheet 51 are fed between the auxiliary paper-table 22 and the platen 11 at the rear side of the latter, and are rolled forwardly and upwardly by the feed-rolls 18 and the platen to have their leading endspassed behind the blade 44 and inserted through either one of two slots 69 of a hollow spindle 70 of a take-up roll or spool, generally designated as 71. Each take-up spool includes a left spool-head 72, to which is integrally joined an inreaching stub-spindle 73 which extends through a bearing hole in the left side plate 42 to have fastened to it, by flat-head screws 74, two cylindrical shell-portions 75 of the spindle 70, each portion having a cross-section slightly less than 180 in angular measurement. Adjacent the right side .plate 42 the shell-portions are fastened by flat-head screws 76 to a stub-spindle 77, journaled in the right side plate 42 and extending rightwardly therefrom to be integrally joined to a finger-wheel 78.

According to one use of my invention, a series of the statement-sheets 29, each previously printed with name and address (not shown), and arranged in alphabetical order, may be fed to the platen l1 seriatim over the rear paper-table 16. Each statementsheet is laterally gaged by the left-hand flange 28, the feed-rolls 18 being thrown off the platen while inserting and gaging a statement-sheet. After bringing the first writing line of the statement-sheet to the printing line, which ma be determined by usual wing-scales (not s 'own), and making the feed-rolls effective, the balance of the customer, which may be taken from the usual ledger-sheet, is now typed in the usual balance-column 80. This balance will be carbon-copied 011 the tally-strip 50, which is disposed under the balance-column, the tally-strip device 40 being positioned there fore by means to presently appear. The platen is now line-spaced ahead, which it will be noted, advances the tally-strip as well as the statement-sheet 29. The lever 19 is now operated to release the feed-rolls 18, and, while the statement sheet is removed with the left hand, the finger-wheel 7 8 may be revolved slightly to take up the slack caused in the tally-strip for line-spacing the platen ahead. In most cases, however, it will not be necessary to take up the slack in the tally-strip after each line-spacing operation, since the tally-strip will usually be disposed in a loop on top of the platen (Fig ure 2) as the line-spacing proceeds,.and the finger-wheel 78 can be operated at convenient intervals.

To prevent the tally-strip from unwinding, a friction-brake is arranged for the ta e-up spool 71 by mounting a leaf-spring 81 on the left side plate 42 by a screw 82 and making the spring with two upwardlyextending integral forks 83 which are disposed on each side of the stub-spindle 73 and bear against the inner face of the spoolhead 72 with a light ressure.

To guard against t e tally-strip 50 being unrolled from the spool 52 faster than the platen 11 and feed-rolls 18 line-space it ahead, a friction-operated braking means is provided for engaging the spool 52. Two

rake-arms 84 are pivoted on the rod 43,

one being disposed against each side plate- 42 and carrying an inreaching brake-shoe 85 having a beveled work-face 86 inclined for frictional engagement against the beveled periphery of the adjacent spool-head 53. To press the brake-arms 84 against the spool-heads, two springs 87 are coiled about the rod 43, one spring being disposed adjacent each arm and having its inner end fastened to a screw 88, which is threaded in a collar 89 and holds the latter in place on the rod 43. The other end portion 90 of each spring 87 extends rearwardly alongside the adjacent arm 84, to press down on the brake-shoe 85, and has a tip-portion 91 bent down in front of the shoe for making its engagement therewith more secure. Each arm 84 has a downwardly-extending finger 92 which engages against the outer face of the adjacent spool-head 53 and prevents lateral'movcment of the spool 52.

To enable the tally-strip device of the present invention to be quickly located on the top of the collating table 25 to register with the balance-column of anyone of several. statement-sheets 29 of varying widths and positively held against lateral displacement upon usual return of the platen-frame to the right, a rack-like group of rectangular notches 93 are cut in the top edge portion of the body-section 26 of the collating table and a rack-like group of like notches 94 are cut in the body-section 27 in the top edge portion thereof. Each notch in the section 26 has a paired relation with one of the notches in the section 27, and is spaced from the notch with which it is paired a distance equal to the distance between the side plates 42. The widths of the notches 93 and 94 are made just wide enough to receive the side plates 42 with a snug lit. It'will thus be seen that the slots 48 in the sideplates 42 and the notches 93 and '94 co-operate to locate and hold the tally-strip device 40 firmly at predetermined positions on the collating table. After a series of statement-sheet balances have been listed, the strip 50 may be severed acrossthe blade 44, and the tally-strip device may be readjusted along the table of the machine as a unit for a new series of statements.

It will be understood that the tally-strip device 40 can be used for other purposes than that described hereinbefore. Also it can "be attached to and used with a typewriting machine having only one collating table, or a machinehaving an auxiliary rear paper-table for manipulating a recordsheet which may overlie the tally-strip.

The notches 93 and 94may be regarded as locating means to quickly position the tally-roll device upon the collating table relatively to a work-sheet, and the aws or slots 48 of the device are operable independently of said notches 93 and 94 to bind the tally-device firmly upon the collating table at any desired location thereon, because the weight of the device is overbalancing, being offset from the plane'of the slots 48 and the tables 26 and 27.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
