CAR-BUFFER.

SPECIFICATION forming part of Letters Patent No. 558,209, dated April 14, 1896. Application filed February 28, 1896. Serialll'o. 581,191. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, WILLARD F. RICHARDS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful lmprovement in Car-Buffers, of which the fol lowing is a specification.

This invention relates to that class of carbuffers which are designed more particularly for freight-cars and which comprise, essentially, a base-plate secured to the end sill of the car and having a forwardly-projecting socket, a tubular follower guided in said socket and having a closed front end which forms the buffer-head, and light and heavy buffer-springs arranged concentrically in said socket and hollow follower.

My .invention has for its object to provide simple and inexpensive means for preventing complete withdrawal of the follower from its socket and for holding the same against turning therein, so as to avoid excessive wear of the parts.

In the accompanying drawings, Figure l is a side elevation of my improved buffer. Fig. 2 is a longitudinal section thereof inline 2 2, Fig. l. Fig. 3 is a face view of the buffer, with one-half thereof shown in cross-section.

Like letters of reference refer to like parts in the several figures.

A is the base-plate, which is secured to the outer side of the end sill of the car and which carries the horizontal socket B, projecting forwardly therefrom.

C is the tubular follower or sleeve sliding in the socket B and closedat its front end to form the buffer-head C, while its inner end is open.

D is the light bufferspring arranged in the socket and the follower and bearing at its ends against the base-plate A and the head or front end of the follower in the usual manner.

opposite sides with projecting longitudinal ribs or tenons f, which engage in longitudinal grooves g, formed in the adjacent inner wall of the socket B, whereby the follower is prevented from turning in the socket, but permitted to slide freely therein. The grooves of the socket are preferably formed by hollow enlargements G, arranged lengthwise on the outer side of the socket and opening into the latter. 4

I-I represents keys or stops which limit the outward movement of the follower, so as to prevent the entire withdrawal of the same from the socket, and which pass transversely through slots or openings g', formed in the hollow enlargements G, and through longitudinal recesses f, formed in thefollowerribs f. These recesses form stop-shoulders f2 on opposite sides of the keys H, which shoulders strike the keys at either extremity of the movement of the follower. The keys preferably consist of short straight bars of wrought iron, which are bent at their ends after being inserted in the openings of the enlargements G, so as to retain them in place. This means of preventing turning and withdrawal of the follower is very simple and cheap, as the only parts which are separate from the socket and follower are the keys, the ribs and grooves being cast integrally with the socket and follower, respectively.

I claim as my inventionl. The combination with a base-plate adapted to be secured to the end of a car and having a forwardly-projecting socket, provided with an internal longitudinal groove, of a tubular follower guided in said socket, closed at its front end and provided on its outer side with a rib or tenon engaging in said groove, a key extending transversely through the longitudinal groove of the socket and limiting` the outward movement of the follower, and a buffer spring or springs arranged in said socket and follower, substantially as set forth.
