Specification of Letters Patent. militia and June 3,1904. seal No- 210,905.

Patented Sept. 3, 1907.

. county of Onondaga and'State of New York, haveinvented certain new and useful Improvements in Type- Writing Machines, of which :the following is a specification. i i

This invention relates to typewriting machines and more particularly to. the paper feeding mechanism thereof.-

The main object of'the invention is to provide a device whereby cards, envelops or other forms of paper may be held in close contactwith the platen and. written npon even to their extreme edges. i

To this and other ends which will subsequently ap-- pear, my invention consists of certain features of constrnction and combinations of devices which will be hereinafter set forth and particularly pointed out in bodying my invention. Fig. 21s a sectional elevation taken on the plane represented by the line I of Fig; 1. Fig. 3 is a. plan view showing a portion of the end of the spring-mounted marginal paper finger and sections of the guide or pressure wiresor fingers of the central paper or card holder. Fig. 4 is a perspective view of the support for the paper or card holder. Fig. 5 is a perspective view of the paper or card holder proper. :Fig. Bis

a perspective of one modification of the same;

Inthe drawings the invention is shown as applied to the Monarch typewriter, but it is to be understood that it may readily. beadapted to other typewri ting maehines." i

I Like parts are represented by like numeralsthrough-' out the several vie v '1 designates corner posts sustaining a top plate 2 above whichare, mounted the rails 3 which support and guide the platen carrier 4. Mounted in the platen carrier is a'iplaten 6, which may be moved step by'step in the printing direction and line-spaced and returned in a manner well understood. At the front of the platen, secured toar'm's 7, isa double scale 8 which is formed with a longitudinal recess 9;' and supported in the ends of the platen carrier above the platen is a rod 10 on which are slidably mounted the marginal guides or spring pressed paper fingers ll1.- The end of each paper finger is'bent forwardly and formed with a-cam face or edge 12-for a purpose hereinafter explained.

The card holder support and the central paper or card holder, which will now be described; are secured to the front of the vertically disposed segmental frame plate IS. The support l4 for the card holder is prefer. ably made ofshect metal and is formed with side arms 15 and acentrally depending arm 16, the latter terminating in a horizontallip 17 which serves as a stop for the. card holder proper. Each of the arms 15 is provided with a pair-of horizontal cars 18 near the outer ends of pair of holes being in a line substantiallytangential of the platen. Centrally of the support 14 openings 20 are provided and through the latter pass'headed screws 21 by which the support is screwed to the segmental plate 13.

"The card holder proper "22 is preferably formed of fine, spring wire, such as piano wire, which is bent into the shapeof a U and then the side portions 23, which are the guide fingers of the card holder, are passed up through the holes 19, after which the ends 24 are spread or flattened out.. To the bottom of the. U a suitable finger piece 25 is secured in any desired manner, as by soldering.- After the card holder proper 22 has been thus assembled in its support 14 it is attached to the fixed plate 13 by the headedscrews 21 which pass through the openings 20 in the support 14 and in the plate 13 and are screwed into tapped holes in a suitable backing plate or nut 26.

intoworking position where it is held by the friction between the fingers 23 and the guiding holes it), through which the said'fingers pass and by which they are guided. When in this working position, as best ap peers in Fig.4, the. fingers 23 are tangential to the platen, while the flattened ends More disposed one at eachside of and ashort distance from the printing point 28 and so that a line 29 drawn toconncct the tops of said flattened ends would be parallel to and slightly below the printing line.

The card 30 or other substance to be written upon is guided and held near its side edges by the marginal fingers 11, but there always is more or less tendency of thecard to buckle or stand sway froinlhc platen between these, marginal fingers, and especially is this the case when the top or bottomof the card is at or in the. vicinity of the printing point. This buckling or bulging is' more marked the greater the distance there is between the two marginal fingers, such distance usually depending-on the length of the card, or the thicker or more'resilient the card is.. It is'one of the purposes of this invention to remedy this objection and hold the card incontact with the platen at the printing point; but it will, of course, be understood that though the invention may be best employed in conjunction with marginal paper guides or lingers, it may nevertheless be used separately and apart l'rom such marginal lingers, or guides, andthe small marginal iced rolls which frequently accompany such guides or lingers. The relation between the central paper or card holder 22 and the platen (l is such that the llattened ends 24 oi the lormer exert a pressure against the surface of the platen towards its axis. The position of the said ends 24 in relation to the printing point is such that the pressure above relerred to is so exerted against the card 30 that though it be comparati'vely thick and resilient it may nevertheless. be written upon even at; the extreme edge ol' the top or bottom. This may he accom plished although the wirting takes place alter the bottom edge has escaped from beneath the upper edge of the scale 8, which serves to hold it, and would spring away from the surl'aee ol the platen, at and near the printing point, but for the restraining'inlluence ol the lingers 23. ll while the card holder is thus l'rietionally held in working position, the movement of the platen carrier to the left or right brings either of the marginal paper lingers ll into contact with either of the spring lingers 23, the cam lace l2 ol' the paper linger Ill eontacting with each't il the lingers 23 in turn. cams them away from the platen in a manner shown most clearly in Fig. fl. and permits the marginal paper linger 11 to readily move past, alter which each linger 22', of the card holder springs back into contact with the platen or the card thereon.

When the card holder is not needed, it may be lowered to non-working position by pressing, down upon the linger piece 25 and thus moving the card holder longitudinally downward until the linger piece 25 contaets with the lower stop 17 do this position the ends 24 are opposite the recess 5) in the scale 8. It will be evident that when the card holder is in its lion-working position it is out of contact with any of the moving parts oi the machine. and unnecessary.l'rietion or rubbing is avoided.

The working position of the llattened ends 24 with relation to the printing point may be altered by loosening the screws 21 and moving the support l4 upor down, thus changing the position of the lower ears lb which, it will be recalled. serve as the limiting stop lor the upward movement ol the card holder 22.

The modified form shown in Fig. ti has the side wires 3] ol the card holder joined at the top by a cross-wire 32 which is formed with a central depression 33 to ailord a passage lot the type block's ol the type bars. In practice the side and top portions of this nioditieation .would prel'erably be ol one piece, which, alter it had been bent to the desired shape, would be passed down through the openings It) in the holder. alter which the ends Ill would be bent in and the linger piece 35 would be suitably secured thereto. I

For the-sal e oi brevity the invention has been frecard holder but it is to be understood. ol' course, that it is applicable to paper, envelops, and to other substances to be written upon as Well as to cards.

lt will be seen that. l have provided a pressure device for guiding. lei ding, controlling and holding the card in contact with the platen at and n ar the printing point; that thi pressure device serves a: a means for quently referred to as a holding the paper against the platen while the paper and platen are traveling and is arelati'vely lixed means; that the relatively lixed means t'or holding the paper against. the platen is so constructed as not to interfere with the relatively moving means tor holding and guiding the paper near its side edges, that is, the marginal paper lingers: and that the pressu e device is so eonstrncted that. it may be used in a front. strike typewri't ing machine to guide, feed, control and hold the paper or card in the vicinity oi the printing point alter the bottom edge of the paper or card has escaped from beneath t'he top edge of the scale. The flattened tops of thelingers 23, also serve as a guide to the re-insertion and adjustment oi' cards and paper, when correcting is being done. The cross bar 32 of the modified form serves a similar iuuction.

Various changes in detail construction and arrangement may be made without departing lrom the gist of the invention as expressed in the following claims.
