a is the segment that has at each of its ends an aperture '1" to receive pins ]t' at the lower corners of the vertically disposed card clamp or guide j.

'm indicates a well known form of type bar guide and n a well known form of ribbon vibrator located in rear of the guide.

Between the printing surface of the platen 0 and the rear of the ribbon vibrator is located the card holder j that may be appropriatcly mounted in any suitable way upon the machine, as, for instance, in the way shown in l ig. 1.

On the lower plate of the type bar guide m at each end or side thereof is an upright projection 9' that may be turned inwardly or rearwardly sufficiently to bear against the lower edge of the card holder j and hold it out of contact with the ribbon vibrator.

The card holder is shown detached in Fig. l in trout elevatimi and in top plan in Fig. 2. It comprises a flat plate to which the letter j has been applied. its upper edge has in it an oblong recess a of suitable width and ot' sullioient depth to accommodate the type bar hoads; --that is to say, to permit 4 the type to make impact against the platen. To the right and left of this opening a the plate is formed with openings 2, t, which are preferably triangular in shape, as shown, or otherwise, and the plate at the straight bottom edges of these openings-is engraved with a scale a. The small tongaes or projections 6 formed ol the sheet metal of which the card holder plate is formed and projecting into the openings I, serve to prevent an inserted card envelop or sheet from entering either of the openings or striking against the edges or walls thereof. Beyond the flat central portion of the plate having the openings t, t, the plate is formed tending wings n that are deflected to the front as seen in Fig. 2, the point of delieotion or bend being indicated by the line '0 in Figs. 1 and 't.

An important feature of my construction is the arrangement of the recess .9 in the card holder plate,-that is to say, it is located at occur close to the right hand edge offthat recess the wid th ot' the 'wi th lateral eX- recess being srfrlh us- I tion in rear of the card holder y.

to permit observation of several printed letters opposite the recess as well as others that may appear through the left hand one of the openings 2?. There is less covering of the printed matter than would be the case if the recess 8 were centrally disposed.

The paper clamps h mounted upon the cross bar in rear of the platen so as to be adjustable longitudinally of the platen are hinged so as to be thrown rearwardly into the position shown in Fig. 3, They each comprise the arm it having mounted in appropriate bearings in its front end the paper clamping roller 7L2. This roller has a shaft 71, turning in hearings in lugs turned up at the sides of the arm 70. On this shaft is hinged a sheet metal finger or margin paper guide plate that is curved to conform to the front face of the platen and when down,- that is, in operative position; as in Fig. 5, its lower edge overlaps and lies against the front face of the scale bar 6. .There is therefore, little, if any opportunity for an inserted card to pass to other than its proper posi- A fiat spring g is attached by screw q to the arm h and extends to the forward edge of the latter. Beneath the spring the arm has a slot whose rear wall is indicated by the dotted line if, Fig. 2, and which extends to the front edge of plate h. The hinged guide 7) has a curved finger 79' extending rearwardly from its rear edge over the spring q and the upward reaction of the spring tends to hold the guide down in operative position. When the guide is turned up into inoperative position, the lip p forces the spring down until the edge of the lip passes the center of motion when the reaction of the spring tends to throw the guide up. With this arrangement an inserted card may be held closely against the face of v i the platen-and printing may be done thereon very close to the top and bottom edges thereof. If it is desired that the printingupon the card shall extend to the extreme side edges thereof, then the fingers or guides 79 may be moved upwardly on the front hinge portions. It is obvious, therefore, that the guide finger p, and clamping member comprising the arm k may be moved upwardly together for any desired reason. When writing on side edges of cards or paper the finger p, which serves primarily to guide the paper or card from the scale to the roll in arm in, may be folded back on ts hinge over the arm 7:. without raising the latter. The surface of the clamping member coiiperating with the platen is shown as a roll and is preferably such. The guide 79 is preferably sheet metal and is shown as such.

I claim:

' l. A card holder for a visible typcwriting machine adapted to be mounted in rear of the ribbon vibrator adjacent the face of the platen and having an opening through which the type impinge against the platen the right hand edge of which opening crosses the printing line to the right of the printing point and closely adjacent thereto and the left band edge crosses the printing line a substantial distance to the left of a vertical line passing through the printing poin't.

:2. A card holder for a visible typewriting machine adapted to be mounted in rear of the ribbon vibrator adjacent the face of the platen and having an opening through which the type impinge against the platen the right hand edge of which opening crosses the printing line to the right of the printing point and closely adjacent thereto and the left hand edge crosses the printing line a substantial. distance to the left of a vertical line passing through the printing point, and also having side wings extending from the central portion of the holder at each side obliquely forward.

3. A card holder for a visible typewriting machine adapted to be mounted in rear of the ribbon vibrator adjacent the face of the platen and having an, opening through which the type impinge against theplaten the right hand edge of which opening crosses the printing line to the right of theprinting the platen and the ribbon vibrator, combined l with margin clamps adjustable longitudinally of the platen and each composed of a forwardly extending arm adapted to be swung upwardly and rearwardly away from the platen and a clamping finger hinged in the front end of said arm bent to conform to. the surface of the platen and extending across the front face thereof and, adapted to be swung upwardly and rearwardly out of operative position.

5. In a visible typewriting machine, a margin paper clamping and guiding dev ce comprising a paper clamping member coacting with the platen above the prlntmg line out of the paths of the type when they are making an impression and a paper guide movahly attached above the line of print to the clamping member and extending downward across the printing line and mounted and adapted to be moved away from the 'out of operation.
