VVILLARD F. RICHARDS, OF BUFFALO, NElV YORK, ASSIGNOR TO THE GOULD COUPLER COMPANY, OF NEW YORK, N. Y.

CAR-BUFFER.

SPECIFICATION forming part of Letters Patent N o. 574,576, dated January 5, 1897'. Application led September 18,1896. Serial No. 606,204.. (No model.)

To ctZZ 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 new and useful Improvements in Oar-Buffers, of which the following is a specification.

This invention relates to that class of carbuffers which are designed more especially for freight-cars an d which consist of a forwardlyprojecting socket secured to the end sill of the car, a tubular follower sliding in said socket and havinga closed front end forming the buffer-head, and light and heavy buffersprings arranged in said socket and thehollow follower.

The object of my invention is the provision of simple means for limiting the outward movement of the follower in its supportingsocket, so as to prevent the complete separation of the follower from the socket.

In the accompanying drawings, Figure l is a side elevation of my improved buffer. Fig. 2 is a front view thereof. Fig. 3 is a longitudinal section of the same in line 3 3, Fig. l. Figs. 4 and 5 are vertical cross-sections 5 5, Fig. 3, respectively.

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

A is the horizontal socket, which is secured to the end sill of a car, preferably by bolts passing through openings a, formedin the bottom or closed rear end A of the socket, and which is preferably square or rectangular in form, as shown.

B is the tubular follower arranged to slide in the socket A and having its rear end open and its front end closed to form the bun-'erhead B. The follower is square or rectangular to conform to the socket A. By constructing the follower in this manner the bufferhead presents a comparatively large bufling or contact surface.

C is the light budeisprin g arranged partly in the socket and partly in the follower and bearing at its ends against the bottom of the socket A and the head B of the follower in a well-known manner.

D is the heavy buffer-spring, which bears at its rearend against the bottom of the socket and comes into action when the resistance of the light spring is overcome. The follower is provided in its upper and lower walls on opposite sides of the buffer-springs with longitudinal slots e, and the adjacent walls of the socket A are provided in line with said slots with openingsf.

G represents stationary stop pins or bolts which pass through the openings f of the socket and the longitudinal slots e of the follower and which limit the outward movement of the follower in the socket, thereby prevent` ing its complete withdrawal from the socket. These stop-pins are coniined in their openings by keys g, passing through their projecting lower ends. Upon removing these keys the stop-pins can be removed and the follower can be withdrawn from the socket for making repairs or renewing the buffer-springs.

I claim as my inventionl. The combination with a socket adapted to be secured to the end of a car, of a tubular follower guided in said socket and provided near one side thereof with a longitudinal slot, a stop pin or bolt passing through said socket and the longitudinal slot of the follower, and a buffer spring or springs arranged in said socket and follower, substantially as set forth.

2. The combination with a socket adapted to be secured to the end of a car, of a tubular follower guided in said socket and provided in its. upper and lower walls and near opposite sides thereof with longitudinal slots, stoppins passing through said socket and the 1ongitudinal slots of the follower, and a buffer spring or springs arranged in said socket and follower, substantially as set forth.

fitness my hand this 28th day of August,

WILLARD F. RICHARDS. lVitnesses:
