TYPE-WRlTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 716,770, dated December 19021 Application filed November 9, 1901. Serial No. 8 ,743. (No model.)

To all whom it nut-y concern:

Be it known that I, CHARLES H. SHEPARD, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the countyof Kings and State ofNew York, have invented certain new and useful Improvements in Type-Whiting Machines, of which the following is a specification.

My invention relates to card-holders for type-writing machines; and the object of the invention is to provide simple, inexpensive, and efficient means ready for use at all times.

To the above ends my invention consists, essentially, in a platen having a card-receiving groove or slit formed therein and in the construction and arrangement of the parts, as hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein a sufficient number of parts of a type-writing machine have been shown to illustrate my invention, Figure 1 is a plan view of a platen and platen-frame, the view illustrating a card introduced into the card-holding means, together with a card inserted in the groove or slit in the platen. Fig. 2 is a side view of the same. Fig. 3 is a transverse sectional view through the platen and platen-frame, the view illustrating a card secured in place and ready for printing. -Fig. 4 is an enlarged fragmentary transverse sectional view of the platen with a card in place.

The invention in the present instance is shown in its application to the platen and platen-frame of a No. 6 Remington type-writing machine, though obviously the invention may be applied to the platen of any other make of machine. The platen-frame 1 is provided with a cylindrical platen 2, that is adapted to rotate in suitable bearings 3, and may be provided with one or more fingerwheels 4 for rotating the platen by hand. One end of the platen may have secured thereto a line-spacing ratchet-wheel 5, which cooperates with suitable line-spacing mechanism, (not shown,) the wheel and platen being retained against accidental displacement by a spring-pressed roller 6, which bears on the teeth of the ratchet-wheel 5, whereas the spring 7, which supports the roller 6, is secured to the platen-frame at 8. The platen 2 comprises the usual wooden core 9, through which the central shaft 10 of the platen may project. This core is surrounded by a rubber sheath 11, which is provided with a groove or slit 12, that preferably extends substantially throughout the length of the platen, as indicated in Fig. 1. This groove 12 is inclined with relation to the surface of the platen, as shown in Figs. 3 and 4 of the drawings, and the width of the groove is preferably substantially the same as the thickness of the cards or stiff paper to be introduced therein. The groove is preferably formed by a thin circular saw and preferably extends entirely through the sheath 11 and terminates at the core 9 of the platen. It will be understood that the core which constitutes the bottom wall 13 of the groove 12 is parallel with the surface of the platen and forms an abutment or stop against which the leading end oredge of the card may be squared when it is introduced in the groove, and hence it is unnecessary to rely upon the eye. of the operator for determining whether or not the card is properly squared or positioned in the groove and upon the platen.

To connect the card with the platen, so that the card may be carried by the latter, it is merely necessary to rotate the platen 2 until the groove 12 is uppermost, as shown in Figs. 1 and 2,and to insert the card 14 within the groove. The platen may then be rotated in the direction of the arrowin Fig. 1 until the card is brought to the position shown in Fig. 8 of the drawings, in which position the paper-feed roller 16 is in contact with the" card and cooperates with the platen to bend the card tightly around the platen and to cause it to turn with the platen. It will be understood that in this position the leading edge of the card is operatively connected. to the platen by reason of its insertion in thegroove 12, and the card is prevented by the Wall of the groove from being accidentally detached or released from the platen by its own resiliency. In otherwords, the'inserted portion of the card. is gripped and held by the walls of the narrow slit, and the card remains properly in place upon the surface when the body of the card is held against the surface of the platen by the pressure-roller. In the position of the parts shown in Fig. 3 the card may be written upon in succeeding lines, and after the printing is completed the platen may be turned in either direction to bring the card to a position substantially such as is indicated in Fig.-

2 of the drawings, where the card may be withdrawn from the groove.

The degree of inclination of the

side walls

12 and 12 of the groove 12 is preferably such that the leading end of the card will not be cracked or injuriously bent when the card is in printing position, as at Fig. 3, but is sufficient, however, to preventthe leading edge of the card from escaping from the groove or springing away from the platen after the card has once been inserted therein and turned to the printing position.

By having the groove 12 extend substantially throughout the length of the platen cards of various widths may be received within the groove. The groove or slit being very narrow and preferably formed between notches of the line-space ratchet-wheel, the platen is adapted also for printing upon or dinary thin paper.

It will be observed that by my present invention the platenitself is constructed to hold the card without the use of supplemental clamps, catches, and the like,as heretofore that is to say, no device additional to the platen is necessary to enable the platen to receive and hold the card in place.

\Vhile the groove 01' slit 12 is shown as cut through to the core 9, it will be understood, of course, that the cut may be made only part way through the sheath or cover 11 and only deep enough to properly hold the card. There is this advantage in providing a shallow groovenamely, the card may be printed upon much closer to the edge if only a very small portion of the card be placed within the groove.

What I claim as new, and desire to secure by Letters Patent, is

1. In a type-writing machine a platen having a card-receiving groove formed in the surface thereof, the walls of said groove being inclined with relation to the surface of the platen and constituting the means by which the card is prevented from springing away from the platen.

2. In a type-writing machine, a platen having an inclined card-receiving groove in the surface thereof and which extends substantially throughout the length of the platen,

the walls of said groove constituting the sole means by which the inserted portion of the card is prevented from springing away from the platen.

3. In a type-writing machine, a platen having a card-receiving groove in the surface thereof, the side walls of said groove being inclined with relation to the surface of the platen, and the bottom wall of said groove being parallel to the surface of the platen and adapted to constitute a stop against which the paper or card may be squared when it is inserted in said groove.

4. In a type-writing machine, a platen havinga core and a sheath surrounding said core, said sheath having a card-receiving groove which extends therethrough and terminates at the core.

5. Ina type-writing machine, a platen having a core and a sheath surrounding said core, said sheath having a card-receiving groove which extends therethrough and terminates at the core and the side walls of said groove being inclined with relation to the surface of the platen.

6. In a type-writing machine, a platen having a core and a sheath surrounding said core, said sheath having a card-receiving groove which extends therethrough and substantially throughout the length of the platen and terminates at the core.

7. The combination with a p'ressureroller, ofa cylindrical platen having a rubber sheath provided with a longitudinal slit to receive the card; the walls of the slit alone being adapted to grip and hold the inserted portion of the card when the body thereof is held against the surface of the sheath by the pressure-roller.

8. In a type-writing machine, a platen having a card-receiving groove in the surface thereof, the width of the groove corresponding substantially to the thickness of the card or paper to be employed in connection therewith, and the side walls of said groove being inclined with relation to the surface of the platen and the bottom wall of the groove being parallel to the surface of the platen and adapted to act as an abutment against which the leading end of the card may be squared.
