TYPE-WRITER CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 752,106, dated February 16, 1904.

Application filed March 13, 1903.

justed upon the carriage for the purpose of bringing said platen into exact parallelism with the direction in which the carriage travels and also of adjusting the platen bodily, if

desired, and, furthermore, of taking up whatever end play there may be between the platensupports.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure 1 is arear elevation of the carriage with parts broken out. Fig. 2 is an end view with parts in section, and Fig. 3 is an enlarged detail view of one of the platen-adjusting devlces.

A indicates the body of the carriage, which is adapted to travel lengthwise of the supporting-rod B. This body is provided with two circular sockets A, preferably in the nature of clamps, one of these sockets being located at each end of the carriage. Each socket may be contracted to exert a clamping action by means of a screw C. In each of the sockets is mounted to turn a lug D, in which is journaled eccentrically a rodor pin E. Around this pin is fitted loosely or rigidly an eye F, which is located at the rear end of the arms or hooks F, which at their forward ends engage the platen G. The platen also engages inthe usual manner aframe H, which in this case is an auxiliary frame capable of independent movement relatively to the body A. The auxiliary frame H carries the pawl I, which is Serial No. 147,578. (No model.)

employed to rotate the platen by means of the ratchet-wheel G.

It will be understood that inasmuch as the pin E is eccentric with relation to the socket A arotation of the lug D will cause the center of the platen to be moved forward or rear- Wardthat is, the distance between the platen and the supporting-rod B may be altered. Inasmuch as there are two independent adjusting devices connected with the platen at different points of its length, it will-be obvious that by their aid the platen can be brought into exact parallelismwith the supporting-rod Bthat is, with the direction in which the carriage travels-which parallelism is essential to a uniform action of the types at every portion of the platen.

My invention is generally applied to a frontstrike type-Writer, and to illustrate this I have indicated one of the type-bars J in printing position in Fig. 2. In such a machine a further advantage is secured in that the platen may be adjusted bodily toward and from the printing-point in a direction from front to rearthat is, in a direction perpendicular to the plane or face of the type when the latter is in the printing position. I may thus bring the platen farther to the rear in case very heavy paper or light cardboard is to. be writ-- ten upon.

, I desire it to be understood "that various modifications may be made without departing from the nature of my invention.

To enable the lugs or bushings D to be readily turned, I may provide them with flat surfaces D'. In the particular structure shown the two pins E, which fit into the said lugs or bushings, are portions of one and the same rod, which also constitutes a pivot or hinge connecting two carriage portions. This, however, is not absolutely essential.

I clairn- 1. In a type-writer the combination of the carriage, arms at the ends of the carriage, a platen-carrier engaged by said arms, an independent movable eccentric for connecting each of the arms adjustably with the carriage to permit of separately changing the distance between the carriage ends and that portion of the platen-carrier which is engaged by the respective arms, whereby the platen may be brought into parallelism with the path of the carriage.

2. In a typewriter, the combination of the frame having a track, the carriage-body movable on said track, a platen-carrier held to move With said body, and an independent adjusting device for each end of the platen-carrier to move the corresponding platen end toward or from the carriage-track, whereby the platen may be brought into parallelism with the path of the carriage.

3. In a type-writer, the combination of the carriage, arms having an eccentric adjustable connection with the carriage, and a platencarricr engaged by said arms.

4. In a type-writer, a carriage provided with sockets, lugs mounted to turn in said sockets, pins arranged eccentrically of said lugs, arms connected with said pins, and a platen-carrier engaged by said arms.

5. In a type-writer, a carriage having clamping-sockets, means for compressing said sockets, lugs mounted to turn in said sockets, and provided with eccentric portions, arms connected with said eccentric portions, and a platen-carrier engaged by said arms.

In testimony whereof I have signed my name to this specification in the presence or two subscribing witnesses.

CHARLES DE LOS. RICE.
