To all whom it may concern:

Be it known that LAmLPHUs S; DENNIS,

a. citizenof thoUnited States, residing in- Lakewood, in the county of Cuyahoga and State of Clhio', have invented certain new and useful Improvements in Typo-Writing' Machines of-which the following is a specinism for use in connection with t V machines,- .11 winch one 'or mom to 1 strips lvfy invention relates to tally stripineohaor webs are fed Over the platen in position [to reoeivo tho figures representing totals in itemized accounts or bills, or otl ier lata, the

platen, a. pawl being connected to said key to tlllilfiille tally-strip windin -spool. This throws on said key the burden th of'throwing the feed rolls of? the platen and winding the tally strip, and it is one of the objects f the invention to lino-food the tally strip by Separatormoans, thereby permitting a much lightsr uncl improved notion of said key. To this and tho tally strip spool is mounted on a it'zmne, wl'iich'nnbe swung by tho operator.

"liiohthe J mt o'z idplaten may comp ise a sec-in work-sheets. The tally strips may be fed from supply rolls carried on the swinging frame sup )orted over the platen. the webs bein fed from said rolls downward around the loose sections of the platen and onto winding spools mounted on the axis of the swinging frame. A feed ratchet, Connected to rotate with the winding spools, ac tuated by the pawl. carried by the swingmg frame, the pawl riding idly over the ratchet as the frame is swung forward, and driving the ratchet as the frame is returned, thereby feeding the tally strips forward. Carbon strips may be supplied from spoolsalso carriedby the swinging frame, and extend around the platen over the tally strips, the

leading end of each carbon extending between feed rolls'which may be actuated by a train'of gearing between the winding spool 2 shaft and the feed rolls to feed the carbon strips a short distance each time the tally strips are fed forward.

The work-sheets are held in contact with the platen; and fed forward as the platen rotates, by means of the usual feed rolls.

In order to-perxnit the feed rolls to be lifted for removing and replacin a bill,

and the tally strip to be fed forward by a single operation,- means are provided for an automatically liftingthe pressure rolls from the platen each time the swinging frame is actuated to feed the tally strips forward. Such means may comprise a bell crank act-u 1 ated bysaid swingingframe and connected as through a link to the usual key-actuated link for lifting the feed rolls, a lost motion connection between said links permitting the pressure rolls to be lifted either by the swinging frame or the finger key ordinarily 4a proyidedfor such purpose.

Other features 9nd advantages will hereinafter appear.

In 1:15; accompanying drawings, Figure l a perspective View, showing my invention '45" applied. to the carriage of an Underwood typewriting machine. Rig. 2 is a detail View, showing mea torelease the holding detent'" for the ratcljet wheel. Fig. 3 is a fragmentary sectional elevation, showing the'feed'rolls thrown off the platen. 4

is a part sectional end elevation of the mechanism shown in Fig. 1', the parts being in then noi' inalfposltlon of rest. Fig. 5 is a similar viewyshowing the tally strip frame thrown forward. .Fig. 6 is a front elevation of the "intention, the platen and platen ,framebeingshown in section.

The rotary-platen 1 is mounted upon an axle 2 journal'ed inthe ends 3 and 4 on the 6Q platen frame;.-'which also comprises a tierod'faand-a aper shelf 6 uniting the frame ends. The p aten frame is supported in the usual traveling carriage 7 The platen comprises sectionliia and Z1 fixed to the axle 2,

and doosesec' ions 0 arr-dd overwhieh the link 24 to a crank 25 on the shaft 18. The

the supply spools 33 downwardly around tally strips extend and which are rotatable independently of the fixed sections a and J) to permit independent feeding of the or the line-space mechanism, comprising a ratchet wheel 9 fixed to the axle 2 and r(- so tated by the usual pawl on the reciprocating slide 10 actuated by the line-space lever 11. The main work sheet or bill. 12 is held against the platen and is fed forward when the latter is rotated by means of the usual g front and I'Qlll pressure feed rolls l8 and 1 which bear against the sections a and l) of the platen. These rolls mounted on rods 15 supported on arm. 16 journaled on a tierod 17 of the platen frame, and are adapted rm to he throw off the platen by the usual pressure roll releasing shaft or rod 18 formed with flats or cams 19 adapted, when said releasing shaft is rotated to the Fig. 3 position, to spread extensions 20,01"- the arms 16,-and thus move the pressure rolls away from the platen. The releasing shaft 18 is actuated by a key 21 on a rock shaft 22 carrying a rock arm connected through a pressure rolls are held against the platen by springs 2-6.

The tally strip mechanism is supported on a frame A mounted, to swing or oscillate on a. shaft parallel with the platen and connected at its ends to braclrets zl and 29 on the ends of the platen frame. The swinging frame A may coniprise plates 30 rotatable on the shaft and connected by tierods 31. and 32. The rod 31 forms spindles for the tally strip supply spools 33, and the rod 32 provides spindles to receive the spools Sal from which the carbon strips are supplied.

The tally strips or webs 35 extend from the loose platen sections 0 and d and up to the winding spools 36 upon which the written portions of the strips are wound. The winding or storage spo ols 3% may each com- 1 G prise a sleeve 37 loose on the shaft 27 and end flanges 37, said'sleeves being separately formed for-convenience in assembling, and connected by a coupling 38; to cause the spoolsto rotate together.

The frame A is normally supported in the rearwardly inclined positionas shown in Fig. 4, and may be swung forwardly-to a substantially vertical position, Fig. 5, tc permlt free access to the-paper shelffor res- 13 0 ,moving a work-sheet 'or bill and placing a new one in the machine.

lu order that the tally strips and the r carbons may be automatically fed forwardl by the oscillation of the frame A, a paw anderatchet feeding device is provided, cornprisin a ratchet .wh'eel 39 fixed to a sleeve 371m actuated bya pawl 40 pivoted at 41' to a plate l2 forming art of the swinging frame A. When the name is swung forweirdly, a detent 43 pivoted at 4A to a holds the ratchet wheel 89 bracket plate 45 fixed' to the laten frame, rom rotating with'theirame-so that the pawl 4-0 rides idly over the ratchet wheel.

' ingframe is returned, the pawl engages the windin ratchet, to cause it to rotate with the frame. The winding spools 36 are thus given a step, hy-ste rotation as the frame is oscillated. The etent 43 is held against the ratchet wheel 39 by a spring 46, but may be thrown ed by a cam 47 actuated by a fingerpiece 48, l ig. 2, t0 permit backward rotation "of the spools for removing stored portions 0 the tally strips The ham 4'? has a flat to bear against the detent lever and hold the detent 43 oil the ratchet wheel when the pinion 53 connected to rotate with. the windlng spools 36, an i-dler pinion 5 ljournaied 'on one oi. the plates iifl, andapinion 55 fixed. on a shaft on which the rollers 51 are also fixed. The rollers, are yieldingly held-against the rollers 51 by means of a spring 5'7 bearing against a swinging frame 58 carrying said rollers 52.

When the frame A is swung forwardly, the pinion 53 being held stationary by the detent 43, the idler Iii-rolls on the pinion 53, thereby rotating on its own axis, and thus -,rotates the pinion '55, so that the carbon.

strips extending between the feed rolls 51 and. 52 are fed forwardly by said rolls. During-the. return movement of the frame A, and while the pawl 4H) is in engagement with the ratchet wheel 39, there is no rela-' 1 tive rotation of the pinions 53, 54 and .55; These gears form a speed reduction gearing for effecting only a very small feed of the carbon strips, cachtime the frame is oscillated. The feeding movement,' however, is positive and insures a fresh surface oi the manifoldlngstrips being contlnuously As the swing 1 -mittent rotation to the supplied; Said stri 5 may be provided, as is common, with di erent colored zones, as for example black and red, as indicated 1n Fig. 6.

The rearward movement of the frame A is limited by a shoulder 59 on the plate 45-,

said shoulder being in the path of a tie-rod; 60 connecting the plate42 with an arm 61 journaled on the shaft 27. The forward movement of the frame A may be limited by a pin 62 on the plate 45 projecting into the path of the arm 61, said pin 62.also forming a stop for the fingenpiece 48.

In order to automatically lift the pressure feed rolls 13 and 14 from the platen when the frame A is swung forwardly to permit the insertion of new Work-sheet, the following mechanism is provided: A bell crank lever 63 comprises a vertical arm hav ing a slot to engage a pin 64 on a depending extension of the arm 6]., and a horizontal arm of the bell crank lever is connected to a depending link 65 provided with a slot 66,,

to receive a pin 67 on the link 24. Whenthe frame A is swung-forwardly, the pin 64: is moved. rearwardly and the bell crank lever 63 is actuated to lift the link 65 and. carry with it the link 24 to the Fig. 5 positicn, thus rotating the shaft 18 and throW- ing ed the pressure feed rolls 13 and 14-.

As shown in Fig. .5, the swinging frame A rotates the pressure roll releasin shaft 18 only far enongh to bring the ats or cams l9 to an inclined position, so that when the frame is returned, the springs 26 may also return the pressure rolls to the platen.- When thekey 21. is actuated, as shownin Fig. 3, the shaft 1.8 is.rotated into such position that the springs 26 are ineiective to return the feed rolls 13, 1.4 and the key 21.

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