and upward "to the receiving spool. A presser linger carriesa pressure roll to bear analist the tally strip and hold it in drivinnrelation to the platen, and also carries a guide through which the tally strip extends; said presser linger being 'spring pressed against the platen but movable therefrom to litt the pressure roll and also positively move the tally strip away from the platen, thereby permitting' the platen t0 be rotated and feed the vvorlr sheets independently of the tally strip. Said guide also serves as a tearing edge for the tally strip. The guide linger may be lifted and held from the platen by suitable means, such as` a linger actuated cam. i

Other features and advantages will hereinafter appear.

The invention will be described more particularly in connection with the accompanyine` drawings, in which,

Figure 1 is a front view of a typewriter Carria ha ving our invention applied thereto: Fig. "2 is an end View of the same partly in section on the line 2-2 of Fig. l; Fig. El is a view similar to part of Fig. Z but showing the mechanism in a different .position; Fig. ft is a detail plan view of a presser linger and paper guide.

Our invention can be applied to any type- Writing 1nachine,but it is particularly applicable to machines havingundivided or in'iipartite cylindrical platens and especially to front strike machines, and we have illustrated it in connection with a machine of the latter class. y

teterring to the drawings, l indicates the carriage ofA a typewriting machine and 2 the platen, which is mounted in suitable bearings in the carriage. A bar 3 extends along 'the carriage in front of and below the platen and on this bar is mounted a Lpaper finger 4, which is constantly pressed toward the platen by a spring 4?. Beneath the platen are the paper feed rolls 2a, 2l. These rolls are ot ordinary construction and are yieldingly pressed against the platen in the usual manner byv suitable springs. In the present instance the paper feed` rolls only coperate with the portion of the platen to the left of the tally strip, the rolls which in ordinary typewriting machines would bear on the tally strip being omitted. This permits of feeding the bill blanks or other sheets of paper in the machine without n'ioving the tally strip when the presser finger is raised. lilith the exception of the omission of certain of the feed rolls, the papeifeedii'ig devices shown in the drawing are those of the well known L. C. Smith & Bros. typewriting machine, although any other suitable paper feeding mechanism may be used in connection with our improvements.

At the right end of the carriage we provide a special presser finger or device 5 which is hinged to a suitably lined support 6. As shown, this support is carried by the bar 3, but it will be obvious that it 4may otherwise be secured to the carriage. rl`he presser linger 5 is connected to its support by a hinge joint 7 and is normally pressed against the platen by a spring 8. 'Ihisnger is oli'set toward the center of the platen above the printing plane and in its offset portions are preferably mounted one or more anti-friction rolls 9, adapted to reduce the friction between thev finger and theplaten or paper. At the upper end of the presser linger, and connected witlrthe offset portion, is a paper guide 1() toward the center of the platen and likewise above the printing plane; this guide is preferably in the form of a flat loop adapted to receive and guide a paper ribbon 11, and having a straight upper edge 10a which forms apaper cutter by means of which the tally. strip may be conveniently torn off when it is desired ,to remove a portion of it.

lVe provide means for moving vthe presser linger lto and from the platen-and-for holding it away from the platen When desired. As shown' these means comprise a thumb or cam lever 'l2 pivotally connected to a lug 13 at the right side of the presser linger. 'When this thumb lever is turned -out into the position shown.in Fig. 2, the spring 8 is .permitted to hold the presser finger yieldingly against the platen, or against the paper running'over the platen, and 'when the thumb lever is thrown'into the position shown in Fig. 3, the presser'finger is held away from the platen. W'hile in this position the thumb lever 1:? may rest directly on the platen surface, but we prefer to providev a fixed part lil. against which the thumb leverinay bear.

rlhetally sheet ll'ispreferably a strip or ribbon of paper having awriting surface on .its outer side and having its inner surface covered with a carbon preparation. It will be evident however 'that instead of coatingr the vsurface of the tally strip with carbon a thin strip of carbon may bearranged within the tally strip andv made to travel with 1t.

Upon the rear of the carriage is a support 15 carryingtwo spools16,'17, the former spool carrying' the supply roll 'of the tally .strip and the'latter spool being adapted to receive the tally strip as it leaves the platen.

Ther-2e spools may be of any ordinary constrzieti on. Y For convenience they are removably held upon their spindles by the thumb nuts 18. At the right end of each spool is a. pulley and a band or belt 1f) effects a friction drive between these pulleys so that when the delivery spool .1G is turned the receiving spool 17 willbe turned simultaneously. The spool 16 is turned automatically by the feeding of the tally strip to the platen and as the diameter of the roll on the supply spool 1G is usually-much greater than'the diameter of the roll on the winding spool 17, the diameter of the pulley on thellatter spool is smaller than the diameter of the other pulley, so that the peripheral speed of the.roll on the spool 17 isalways as great as that of the roll on spool 1G and slack in the tally strip is thereby prevented. Undue tension on the tally strip is prevented by slippage olt the band 19 on its pulleys. i

, '.lhe platen may be rotated either by means of the hand wheels 2.1 secured to the ends of the platen axle, or bythe usual line-space mechanism comprising the line-space ratchet wheel Q2.

The operation of the invention when used in preparing bills is as follows: `The end of the tally strip is carried from the spool. 1G over the paper table QG, around the platen, through the guide 1.0, and connected With the core of the spool 1.7. W hen it is desired to insert a bill the ,presser linger is held away from the platen. as shown in Fig. 3. A bill A, together with a carbon C and a duplicate bill B may then `be inserted in thel machine .without disturbing 'the tally strip,

the right ends containing the figure Aeelumms adjustment of-the bill and duplicate the tally istrip willnot. be disturbed ifthe presser finger be maintained away from the platen,'as illustrated in Fig. 3. `TWhen the papers have been properly adjusted for writing, the finger lever 152 is Athrown out and the presser finger permitted to spring a gainel the platen, as shown in Fig. 2. 'l`he typewriter is then operated in the ordinary way and two copies of the items on the hill, to gether `with three copies 4of the figures are produced. lf more than one item is written the tally sheet willbefed forward with the hill. in duplicate on turning the platen. After the last item has been entered on the vbill the platen is'tyurned one line` space to are ordinarilycarried out to the right and by arranging the. bills in the typewriter so thatthe total columns are-under the tally sheet and the item columns exposed only thetetals will'be vprinted on the tally sheet and these 'totals maybe printed as closely togetherl as desired. When' vthe system of bookkeeping 1n use requires daiiy ent-ry of items on bills, the bills are successixfely placed in the typvriter and the amount ofV eaehitein is written on the tally sheet.` By adding upthe items of the tally sheet at the end of each day thetetal of charges for the day -can be obtained. 4In totaling the bills at the endof. the mont-litho totals may 'be `produced on the tally sheetand "added and a cheek on the .dailv' entriesthus obtained.

It will be evidentthatj'v'arious'changes'ln detailsv ofl construction and arrangement may be made lWithout departing from the spirit and scope of our invention,
