TYPEWRITING XACHINE. Application liled April 8, 1926. Serial No. 100,556. infy.invention relates to'lyp@A@i-iting macliliies.aiid 1-tas for its cliicf o@)ject rov,ip SLo,n of 'nenv and iinproved means for and lnlbtliods o-I du ilica'tin@ typenirritten copies, bei z the terni "dufoiicating' ng used in, the bi:,oad serise of il'Oducing any desired nul-nbei, of 'typewritten p COlDieS bf iilatter at i@ single operation. To't-he above ahd other ends, Nvhich will @10 her@inafter appear, my invention consists in the. metlic@ds of producing duplicate, copies and also in the features of coiistruction, coliaminations 6f devices and arrangeiileiits of parts liereinafter described -,ind particulal-ly 11.5 pointed out in the claims.

[5]1,680,973 5 machine, the free end portions of the form applied to the end of t he plate 98 as s hown, sheet and carbon may stick up or stand away. the opei-ator havino, no mechanism to ,Issist froin the platen as indicated at x in Figs. him and relyina so'iei on his h,,Lnds. Af1 and 5. However, these free, end portions will be taken care of by the feed rolls 72 and 73 and other controlling devices on tlle carriage frame as the platen is rotated. It will be understood that in this method of making duplicate copies it is not contemplated 10 revolution. The writing may then be proceeded with, the platen being@ line spaced between the differeni; lines o:r typewriting in thle usual way, it being understood that eacli is line printed through the regular ribbon on the outer form will be duplicated on the underlying form or forms through the carbcin sheet. @ When the forms have been completeI ffiled in, the plaien may be again detached 20 gom the carriage, the written form and its b duplicatinly strip may e unwound and removed, a@'d a fresh form and duplicating stn'p.mav be wound 6n the platen, all in the described manner, this process being repeat25 ed as often as des ired. As has been -stated, *bile I prefer to emPl()y a winding mechanism for ttii-ning the platen when it is outside of the machine, such mechanism is not essential to the pric30 tisiing of my invention, broadly considered, a fact wbieb I have endeavored to bring out more clearly by the illustrations desio-na-ted as Filr,ys. 9 and 10. In the construction illustrated b ,v these figures, the platenemployed, 35 and wbich is designated as 97, corresponds in all respects with the platen 10 of the first described construction, except that the platen-carried clami) for the paper is dispensed y ter the end of the --lieet or strip 101, together with the ustial duplicating sheet 102, been 70 wrapped partlly Ittround the platen, the platen is rolled along the lite or stirface 98 by -ieet the liands of the operator, the sl and duplicating strii) winding on @s it is rolled that the platen will make more than one full , leftward. Con@equently when the platen i-s 75 finally ari-ested by the stops 100 a-s sho%vn by dotted lines in Fi-. 9 the work slieet aiid duplicating strip @Nill be completely ivound in place, as ivill be understood from Fig. 10, which sho",s the platen in the hand of the 80 operatoj,, with the ivork sheet and duplicating strij) flully wouiid thereon and ready to be applied to the typewriting machine to begin' the writing. The pin8 100 not only serve as stops for 8.'v the platen but also act as paper gages or guides. Preliminary @to winding the paper or ivork foi-ni on the pl.aten, saic.1 forill is placed on the table against the guides or pins 100 ,tiid tliei-eby is positioned pi@operly, 90 so that it is tli(,,n oiily necessary to start the platc@n Niith the I)aper froiii the point of b(@(ri-niiiii@,- to liave the paper coi-i@ectly wind tliel-eon. In the di-awing the paper is positi6ned agaiiist the pins wliieli are located in 95 the tliird set of holes, inasinuch as the paper is to be wotind on tho platen three tiliies. If there are to be only two windi,,g,, the paper illser wotild be -aged by the pins ted in the second set of holes, and so on. These pins, i (o of course,,mly be connected to,-ether to act as one, in thc- nature of a bar or f-ence. The consti-tictioll disclosed in Figs. 9 and 10 is wit.h. An ordi ar p n y table or surface for su - 40 porting the platen outside of the maebine may be used, but I prefer a sui port or plate 98 which is provided at its sises with a series of holes 99 disposed in pairs at suitable intervals and adapted to receive detachable 45 and adjustable pegs or -stop I s 100. The holes 99 are spaced apart lengthwise of the table at distances corresponding to the number of wiridings on the platen, so that the platen wben rolled along th@ surface of the plate 98 .50 will make a complete revolution between each of the pairs of peos at the opposite sides of -said plate. As shown, herein, the stops or pegs 100 are arranged in the thircl pair of holes, thus allowing the platen to be 55 rolled along the plate far enough to wind the form sheet 101 three times aroun(i the platen, the form sheet chosen for illustration bein(y of sufficient length f6r this purpose and being provided with three forms. Also at 60 the head of the first form there is a blank se.ace equivalent in length to a quarter of t circumference of the platen, this being ided for I convenience of manipulation. &;@evplaten after havin-a been detached from o5 the machine, as in the pnor construction, is not clainied sl)ecifically in the present case. F rom tlle foreooiiig it will be perceived 10 5 that the esseiitial of my improved method reside s in tcljusting the paper on the platen while it is cletached or apart from the type%vriting intchine co that the, platen m-,ty be appli6 d to the iiitchi.ne with the paper com- 110 pletely adjusted aiid re',,,d for use. ic y A s far as the mechan al devices ai,e concerne d they may be o-,.t-eatly varied ancl any suit,,tb le foi-.m or construction of detachable platen niay be usecl instead of the forms 115 her ein sl-iown.
