Application filed November 6, 1920. VSerial No. 422,329.

To all whom fimay concer/n.' n H Be it known that I, GEORGE A. SETE, c1ti- Zen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have Vinvented certain new and useful Improvements in Typewriting-Machines, of which the following is a specifica-,l tion.

My present invention relates to paper feeding mechanism for typewriting mal chines and'its object generally stated is to providenew andr improved mechanism of the character specified. More specifically the object of theV invention is to provide means for kfacilitating the adjustment of a plurality of work sheets So that they may be accurately alined relatively to vthe printingV point or line and independently of each other.

To the alcove and other ends which will. -hereinafter appear, my present invention consists in the features of construction, co1nl binations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.y Y A v y In the accompanying drawing which illustrates one form of the invention,

Figure 1 isa fragmentary vertical sectional view showing the upper portion of a No. 11 Remington type-writing machine embodying my invention, the section being takenk on planes indicated by the broken dotted yline ca in Fig..2 and looking in i' the direction of the arrow at said line.

Figs. 2 and 3v are respectively right-hand and left-handV Vportions of a two-part or divided platen shown in vertical longitudinal section.

Fig. ais a vertical sectional viewy taken on a plane indicatedby the dottedvyline g/-y in Fig. 1 and looking forward. Y

Fig. 5 isa perspective view of a detail.

Referring to Figs. 1, 2 and 3, the main frame of the' machine includes a top plate 1 above which are secured lugs 2 on which are supported grooved guide rails, as 3, that coperate through antiffriction rolls 4 with the front and rear bars ofia carriagetruck, only the rearV bar 5 being shown, said truck further including end bars 6v connecting said front and rear bars." Shiftably connected with said carriage trucky byvdevicesv 7 is a platen frame or carrier comprising end bars or plates 8 and cross Irods or bars 9 .wel l0, said .platen frame together Wlth the supporting truck constituting a travel-V Specification of Letters Patent. i -Patente'd Oct. 4 192.1.YL

platen, cooperative with Athe front face` f ywhereof is'a combined line indicator and guide 14 that is mounted on the'platen shift-` ing frame of the machine and isvprovided. with an edge or face 15 that registers with or is opposlte to the printing line on the splitV cylinder or two-part platen, the two partsV being equal in outside diameter.. The lefthand platen section o r. element 16v ofl saidV two-part laten is arranged co-axially with' lthe ri lhtandsection or element 1'(l thereof and t ese parts or elements maybe consid- Vered as platens in themselves, they being adapted to accommodate separate work sheets. The left-hand platen orsection 16 comprises. a core 18 of .woody and a sheathvv 19- ofrubber and has Secured toits lefthand end a laten head 20. Said platen head 1s suitab y secured to the interior of a -metal tube or core 23 thatis driven into or otherwise secured'in the bore of the wooden core 18, a dowel pin 24 connectin said head l.

2O with the core 18. Said head ts over theV shaft` 11 and has an outwardly projecting` hub which receives a screw 25 which abuts against the shaft 11 and secures it inffixed relationship withv theY head 20. and the platen or section 16. The shaft 11 bears in a flange or sleeve 26 that is screwed through an opening in the left-hand end bar '8 and is Ylocked in place thereon by a check nut 27. A washer28 is interposed between the sleeve 26.*and the hub of the i platen head 20 to assist in maintaining the platen section 16 properly spaced from the end of the platen frame, The core or sleeve 23 extends rightward beyond the platen 16 y and is provided at its .right-hand end with inturned ears 29 which receive screws 30 whereby the sleeve 23 and the platen section 16 are connected` with platen clutch devices for releasably connecting thcplaten section 16 .with its line spacing ratchet wheel 31.l The platen clutch devices are preferablyof the construction employed in the No.1'11 Remington. typewritmg. machine and lare substantially as disclosed inthe .patent to Woodward'945,358,granted January 4, 1,9101.' Said devices inlude a .Cluwh time?. 99,19.-

operating with an inward .rib l35'on lthe ratchet Wheel' 31 and releasable to disengage said rib b rollers36 Which-coperate with the inner ree ends of said clutch members `34. The rollers 36 are mountedin a.

frame 37 whichl is secured to the inner end of the shaft 12. Said shaft is' adapted to slide through the hub 32 and is normally pressed outward by a coi-ledL spring (not shown) contained in a barrel 38 iixe'd to; hub 32." Thefrib 3510i the ratchet Wheel 31 bears rotatably on said hub`32 and is under-v cut to bear also on-a plate 39 which is secured to" 'Said hub bythe screvv's '30 that pass through therhub' 32 and are threadedintothe ears 29. vPreferably the innerends oft' Athe screwsrreceiv'e' lor coperate with check nutsY Orrdevlces 40 for holding,r or locking them in lace.y VNormally the" clutch men'ilbers 34 Old the `ratchet Wheel 31 in fixed relationship with the sleeve 23 and the platen section 16'so' that line'spacing movement communicated to the Wheel '31- 'bytheusualline y sp'acingdevices ofthe machina-Wilbe transfi mitted-'to' the lplaten 16.

In employing the divided platen or split cylinder in connection with-'typewritten matfound in practice that in the preliminary adjustment ofthe sheets they are likely to become relatively` di sarranged while being introduced into the machine and brought to the first writingline, even though v'correctly alined beforehand. In such case ithas been customary heretofore to" disconnect the two platen'- sections and adjust the left-hand Y work sheet in respectto the linegge 14,15,

f turning the lrighthand finger wheel orv Y twrler, psshig it iii-,w temete hand platen section from control ofthe line l spacing ratchet Wheel 3l so thatY it might be freely turned by saidI twirlen Heretofore,

however, no mechanical meansV have been providedfor. variably adjusting the righthand' platensection underl the circumstances the righthand work sheet and push the y Y Vriglitllian'ol platen around until the paper disconnect the.' clutch devices the fingerk key Y was aline'd-or justiiedloyl the lineY gage to the first line of writingin Vassociation Vwith thel'eftihand work sheet. iThe main objectl of'my vpresent invention is to supply thisv lack and do away with the awkward and Y; unsatisfactory adjustment olf thefrighthand sheet, and vto thisend mechanical means are provided for turning theright-hand platenv section to' any desired extent so as to afford 'Y fine adjustments of the righthand work sheet ir'ldependently` of the' leftfh-and work sheet and platen section. Said means inthe present instance arelshown iniFigsQ 1-3 and comprisefa bevele'd'wheel or pinion76 that withv aV collar178 which receives a set "screw 79 whereby the pinionv is fixed to the shaft 77.
