35 The said bar is guided at its ends in versuch as the stencil card 18, shown in Figures 85. tical slots formed in the ends of-theplaten 2 and 6, the card is slipped into vthe channel frame, and is in the formof a channel, to 19, in the upper side ofa card holdingchancombine stiifnesswith lightness, andalso, nel bar 20, havingjvvithin its channel card to receive a pair of clips which clipthelower holding clips2'1u I The channel bar 20 10-,

Each clip is in the form platen, adjacent it, and having an outside of an upstanding spring lip, which is bent periphery flush With that of the platen. forwardly, to'facilitate insertion of the card, The front surface of each rack 22 is suband a mount whereon saidclipisq secured, stantially flush with the; periphery of the 'tageouslyrotated 1, in

gear 2a, so that these racks lie substantially within a plane tangent to the periphery of the platen 10, as shown in Figuresv 1 and 3. When it is desired to insert a card into the, channel 19, the platen is advanline-feeding direction until the channel bar '20 is in its upper'position, thus bringing the bar almost up to the printing line, atwhich the type 25; prints through the ribbon 20 rises'to this position when the platen is rotated forwardly, inasmuch as the racks are permanently fast to the bar, as by screws holding frame.

20 and the up- 26. The clip-carrying bar form a cardstanding racks 22 together again'stthe front sideof the platen. In orthe channel, to enable end 43, forming 30 a sufiicient hold on theinto exert sufficient pressure upon .the card 18, there is fast to each body a. plate 33 formed as an extension of the wing 27. Each plate 33 curves over the rear side of the channel bar 20, and extends downwardly, and hooks its turned-up extension 34- around a strengthening web 35, formed inte ral with the bottom of the channelbar. T is web of the channel bar gives it great rigidity, combined with the lightness and the small dimensionsnecessary to keep it from interfering with the parts often occup 'ing the space below and in front of the p aten in various makes of typewriting machines, The clips 21 are advantageously made separately from the channel bar, and then slipped-on over theends before the racks 22 are fastened'thereto.

In order to holdthe clips 21 in positions upon, the channel bar, in which their inwardly-facing ends 36 will bear 'frictionally against and serve as gages end ofthe inserted card orstencil frame 18, each body has pivoted thereto, at 37, a friction-locking lever 38, forming a finger-piece, comprising, in the form herein shown,- a U- shaped friction bend 39 and a turned-over. upper adapted to come down outside ofthe front of the channel bar, and thus bind the friction der to give the bodies bend 3:9 against the inner face sufficiently to hold the clip inplace. 'To enable the lever 38, to be released, it; is shown as provided with an extension 42, having aturned-over a finger-piece lip lying close to, but, slightly above, the channel bar, thus enabling the .finger'of the typist to' easily (not shown). The bar 7 for the adjacent extension 40, having an apron 41' grasp it and lift it, to enable the clip 21 to be slid along to a position on the It will be observed that the aprons 41 lie;

entirely outside and considerably beyond the margins ofthe card 18,:with theresult that they need never come near the ribbon-vibrating or type-guide mechanism in any ordinary machine, These. aprons, however, are advantageously quite thin, with the result that if the typewriter carriage should be car ried so far beyond its needed travel as to carry the aprons past a'nytype-guide or ribchannel bar bon-vibrator, it will be likely toclear it. I I

The flare of the wings 27 need be very small,

and need not bring them further forward than the front edge of the channel bar- 20.

In order to steady'the channel bar 20 as it moves up and down with the platen, there may be provided, at each end, a guiding lug or roll lzt'extending into a slot 15 inthe adja'cent'end plate 12, thusmaking it possible to insure'that the channel bar shall always travel in a path clear of any interfering mechanism. The usual bottom feed rolls may be omitted, and, if desired, upper front feed rolls 46, mounted in any desired or usual way, may run upon the edges' l'i of the card 18 to hold it upon, the platen- If the card is a stencil plate, it will havethick edges which are never written on, with theresult that the rolls 46,'r.unning-on these edges, will in no way interfere with the writing.

I In order to give the wings 27 a firmer hold upon a card 18, the lower corners 48'may be given a slight inward that they tend to dig into the card very slightly, not,.however,' enough to mar'it or to prevent its easy withdrawal. 1 y

- It is to be noted that the device of the present invention leaves the front of the platen clear of obstructions and provides for the quick insertion and removal of the cards. It is to be further notedthat the card-holding frame formed by the card-holding bar 20 and the end bars or racks 22 is U-shaped and open at the top, so that the comparatively stiff work-piece, such as the stencil-card "18, may be held by its lower edge only, toprojectvu pward from the card-holding bar 20 into theopen space provided by-the U-shaped frame,'past the printing'line at the front of the platen 10.

Variations may scope of the invention, and portions of the improvements may be usedwithout others. Having thus described my I invention, I claim: u I
