IEAPEB-CARRIAGE FOR TYPE-'WRITING MACHINES.

To all whom it may concern:

Be it known that l, EMMETT M. INSER- SOLL, a citizen of the United States, of lloodstoclt, in the county of ltclclienry and State of lllinois, have invented certain new and useful improvements in. Paperria res for Typel l riting Machines; and it do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciticw tion. This invention relates to improvements in the paper carriages for typewriting machines, and refers more specifically to novel features of construction in such carriages designed to receive and hold on the platen cards or relatively heavy sheets in a manner to prevent the same from shifting on the platen and toprevent them from springing awayfrom the platen by their own rcsiliency, and constructed also to hold such sheets or cards to receive printing impressions close to both the top and bottom inargins thereof. I v

-The invention consists in the-matters hereinafter set forth and more particularly pointed out in the appended claim.

As shown in the drawings z i'. are 1 is plan view of a ty ewriting mac line carriage made in accordance with my invention. Fig. 2 is a cross-section thereof, taken on line- 22 of Fig. 1, showing the parts in position to receive the card. is a showing the platen turned forwardly and with a sheet or carved wrapped partially therearound.

lily improvements herein. shown as applied to the carriage of an Sliver typewriting machine, but said improvements,

may be applied, with whatever modifications may be necessary, to the paper carriages of other typewriting machines.

As shown in the drawings, A A designates the end members of the carriage frame, B B the longitudinal, front and rear members, respectively, thereof, upon the former of which is formed the rack-bar of the letter spacing mechanism.

C designates the nlaten rotatively mounted in the end members of the frame, con sisting of a wooden core C and a rubber covering Q, and provided end turning knobs C and I) D l) designate press-e Specification of Letters Patent.

The means associated with and its platen for receiving a v to be printed and holding it close A on the platen, comprises means rotating. with the platen for receiving the advance or bottom margin of the sheet or and for effecting a gripping action on the \ad- Vance end of the card in the succeeding, rotating movement of the platen. The vancc or bottom margin of the sheet or card is engaged with said holding means on the platen, and the platen is turned in a direction the reverse of that in. which it is to tated in the usual operation the machine to effect line spacing, until the top margin of the sheet is brought beneath the printing point. Thereafter-the direction of rotation of the platen is reversed and it rotated step thy step in the usoz'tlmanner,

es the printing proceeds. v

The means herein shown for t, bottom margin oi the card or sheet W1"? the. platen in. thennanner described consists providing said glaten with a longitudinal groove 0 extending, as herein shown, from end to end of the platen. lhesheet card W adapted to he engaged with said groove at a time when theplaten is ti also 1' to sting said groove at the -receiving side oi the c ria'ge, and preferably above the platen, as shown in Tliereal' cthe platen is turned forwardly, or the verse of its usual step-hy-step line spacing movement, and the engagement of the bot tom inar in of the sh. et or with the groove oi the platen has the effect of wrapping the sheet or card about platen.

in themanner shown in Fig. (the platen is thus turned hackwardly until the pro ect part of the card or is hroio the printing point; and the construction herein shown is such that the printing may be in'ipressed ver the top margin of the sheet. platen is turned forwardly t or card about the lcten, ti

intermediate guide so that the ahixet will be n'eseed Within the groove. is bent at an angle to the body of the card, whereby is eilbcted a frictional or grippii'ig action between the platen and card which wraps it about the platen. "l iere? :r, as the printing proceeds, the platen is turned in its usual direction to produce line spaeing, and the printing may be continued on the sheet or card to practically ottom margin thereof, the only part of the sheet not being capable of receiving the th t unpr ion being that contained an the groove.

.ieature of my invention consists in th' groove 0 in the rubber cover of the platen. so that the part of the rubber covering which overhangs the groove constitutes a flexible lip or flange. By this construction the .:ylindric continuity of the platen is not interrupted, and it equally resilient in character throughout its surface, so that if the sheet or card be of such length as to be Wrapped entirely around and over the groove, the presappreeiahle inequality in the eylindrie suriaee of the platen. The parts of the platen both sides oi. the groove, therefore, will adapted to properly support the paper while the printing is being done.

lfl suaiiy the guide lingers F are movably mounted upon the bar ll so as to be capable of adjustment toward and from each other. i i hen. printing on a narrow card or sheet, said. guidedingers may be moved inwardly into the path of the narrow sheet or card, so as to press the sheet or card against the platen. fi l'ien printing on \vider sheets or cards, hov ver, it. is necessary to provide an A uniformly against the platen throughout its width. in the present in stan the intermediate guide consists of a i p 'e :d to the longitudinalmpporting barii and provided with forwardly and laterally extendingfingers ll." ll which bear 1 upon the upper side oi the platen in the l When printing on a narri i :the intermediate guide it to hold said card or sheet properly pressed manner clearly shown in Figs. 2 and card or sheet, alone \Vlll serve against the platen.

in order to facilitate the .iLSCl'tlOll of the bottom margin of the ('7 card into the groove c, a guideplale is provided which extendsbetween the end frame plates at the rear of the platen and inclined to bring it into the plane of the groove r. The

said guide-plate is located with its edge nearest the platen above the level oi" the axis of the platen and is conveniently atlaehed to the. end frame plates A It by means oi iivets or the lilce exiendinelhi'ough said end trame-plales and flanges i on the said guide plate. This eonstruetion in the paper guide plate oi grea advantage because it enables the bottom edge of the sheet or card to boeasily engaged with or inserted into the. groove by placing the card or sheet on the top oi" the guide plate and thrusting it IiiOlWRU'tl until its bottom edge enters said groove.

1 claim as my invention i'\ typewriting-macliine earriage provided with a rotative platen and a llat guide plate which meets the eylindrie surface of the platei'i at an angle to said surface, said platen being provided with a longitudinal groove disposed at such angle to the part of the cylindrie surface of the platen in which it is formed that it is substantially in alinement with the guide plateivhen the platen is turned into position with said groove adjacent to said guide plate.
