Specification of Letters Patent.

Application filed June LL. 19GB, Serial No, 136,541.

:incl State of New York, have invented oei'- tuin ne and useful Improvements in i e specilication.

This invention relates to the paper--feefh ing and controlling devices of typcwi'it-ing machines. and particularly to means tot feeding tally stiips in conjunction with recoid sheets, that is long sheets which remain in the machine to receive farben copies of successive short bills.

The invention is in the nature oie. nu improvement upon mechanism shown in :in plicetion No. 432,775, filed May 14. 1908, by Henry T. Focldrill. Accoi'clinglo said :ipplication a tally strip is line-spaced simultaneously with the mein sheet` by ineens of a line-spacing mechanism which operated by the platen line-Spacing mechanism. so as to effect an advance of the tellystrip foi' eveiy line of Writing on the bill and record sheet.,

@ne ci the principal objects of the present. invention is to simplify sind im prove the telly-strip medonnism,y especially with :i view to enabling the tally-strip to he odvzincel automatically. not only when the platten spaced, but also when the pressnie rolls me cest oil to permit the Withdiewal of e Weitten bill and the insertion of a new bill v the record sheet remains in the meel Whei'eloy the spacing is automatically peo duced on the telly-strip between the item on one billonci the ii'st item on the next. This spacing the telly sti'ip tween bills is\ effected by the piessuiefroli X'elease key7 and the construction is suoli 'es to cause the pieten strip to eefi twice es et the opeietion oi said space-key es at the operation of bhe line-feeding mechanism of the platen, whereby the successive amount-s on the tally-strip Aare divided vinto gioups, one group ol eachbill.'

According to the pi'esent. invention, the

' tally-strip spool is provided with a ratchet.

Wheel, which may be operatecl by either 'of two powls, one connected to the pressureroll releasediey, and the othei' conneotecl to the line-spacing mechanism oft the platen.

Other features and advantages will here inoter appear.

'A bill oi' main sheet 7 may he inliodnced in he usual manner and teil tox'wmfilly 1i ouncl the platen by the usual pressure rolls 2%, the laitier provided with the usuel release l-:ey 9.

il. telly strip 10 is cmi'ied dow n fiom e clelivery spool 11., and .looped around the platen., and led upwardly anti baelnvzudly to e Yindspool 12. A secon` telly strip 13 may he led fiom o spool le downwardly end looped fennel the tally st-ip platen 1o, and wound upon the spooi 12 simnltsneonslyith the stiip 10; the stiip beingpren' bly cinbonm ized only upon. the side which is next to the strip 107 whereby :in original iecoifl .muy be mode on the unczubonized surface 13, enele strip 10.

The Winding .spool 12 is opera-ted by e natchet wheel 16. povvl 17 to operate the latter is connected to the usuel line-spacing lever 18 which rotates the mafinplaten EL soA that the tally strips 10 and 13 :ire advance@ line by line automatically et the line-spacing movements of the main platen. The lever 13 usually operates e. slide 19, which cai'iios e, pmvl 20 to engage a lineepace Wheel (D1 .f .mounted on the platen axle, whereby the fluplicate recoi'cl my also be mode upon the platen is rotated, and to the rear end of said slide I pivot at 22 one end'of a link 23, the other end of which is pivoted at 24 to the end of a crank 25, which extends up from a rock shaft 26. Said shaft is mounted in suitable bearings 27 and extends from end to end .of the paper shelf 6 in rear thereof, and carries at its right hand end a crank 28, which 1s connected by a link 29 to an arm 30 xhung upon the platen axle 3 and carrying. said pawl 17. The latter is provided With la spring 31 which normally presses the pawl against the ratchet. wheel16. When the slide 19 is in its normal position, Figs. 2 and 4, the pawl is thrown and held out of engage-l ment with the ratchet wheel 16 by an ear formed upon the pawlcontacting with a pm 32, so that the pawl stands normally out of engagement with the ratchet wheel 16, to

permit the latter to be turned backwardly by the operator, as desired.

l/Vhen each line of writing is completed on the bill, the operator repeats the item on the tally strip 13, making a carbon duplicate on the strip 10, and then presses the lever 18 to the left to advance the platen a line, the backward movement of the slide 19 operatingthrough the link 23 to rock the crank 25 and the shaft 26 and the crank 28; the link 29 being caused to pull the arm 30, and the awl 17 being swung into engagement with the ratchet 16 and caused to turn the same a single notch, thereby line-spacing the tallystrips. l/Vhen the operator releases the lever 18, the parts are returned to normal positions by the spring 34, which is usually provided for the slide 19. Thus entries are made line by line on the tally strip as the writing of the bill proceeds.Y

At the completion of the bill, the key 9 is depressed to operate through a link 35 and rock-shaft 36 in the usual manner to release the pressure rolls 8, said rock-shaft having flats or cams 37 engaged by levers 38 which carry the pressure roll shafts 39, and the rocking of the shaft 36 forcing the arms or levers to release the rolls. The link 35 is formed with a tooth or pawl 40 to engage the teeth of the ratchet wheel 16 to advance the tally-strip; the movement of the strip being about twice as great as is effected by the lever 18, so as to produce a space of extra depth between the groups of entries on the tally-strip. The key 9 is formed upon a lever 41 which has suiiicient purchase on the link or pawl 35 to give the latter a stroke equal to two or more notches or teeth of the wheel-16 for this purpose. The pawl tooth 40 normally stands out of engagement with the tooth 16as illustrated,

vto permit the latter to be turned back as required.

The tally-strip spool 1l is carried uponan arm 42, which is mounted 'to swing about the axis of the spool 12 backwardly out of- .the way when not in use; a spring 43 'upon the lower part of Said arm pressing a roll 44 into a seat 45 formed in a stationary bearing 46, to hold the arm yieldingly in working position. To the upper end of said arm 73 42 is pivoted, concentrically with the spool 11, another arm 47, which carries at its upper end the spool 14, and may be swung forwardly to the dotted line position at Fig. 1, to reduce the height of ythe machine 75 when the spools are not in use. A yielding latch or detent 48 is provided upon an extension 49 of the arm 47 to catch over the arm 42, Fig. 8, to retain the arm 47 in working position. l

Variations may be resorted to within the scope ofthe invention, and portions ofthe improvement-s may be used Without others.
