UNITED STATES PATENT OFFICE.

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

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 584,895, dated June 22, 1897.

Application filed March 11,189 7.

To all whom it 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 Improvement in Oar-Couplings, of which the following is a specification.

This invention has more especial reference to that class of twin-jaw car-couplings having a horizontally-swinging coupling jaw or knuckle, a horizontally-swinging look, commonly known as the Gould lock, and a spring for keeping the lock in reliable engagement with the tailpiece ofv the knuckle.

The object of my invention is to improve the construction of the support and abutment of the locking operating-spring.

In the accompanying drawings, consisting of two sheets, Figure 1 is a sectional elevation of a car-coupling containing my improvement, showing the position of the parts when the knuckle is locked. Fig. 2 is a horizontal section thereof. Fig. 3 is a longitudinal section of the coupling viewed from the side opposite that shown in Fig. l and showing the lock swung back and raised, the knuckle being omitted; and Fig. 4 is a horizontal section showing the lock in the same position.

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

A is the usual chambered draw-head; A, the hollow draw-bar; B, the knuckle, and O the pivoted lock.

D and D are the customary inclines arranged in the draw-head above and below the lock for swinging'the lock backward when lifted and forward when released.

E is the link connecting the lock with the usual operating devices, which latter are not shown in the drawings, and passing through an opening in the top of the draw-head.

F is an actuating or thrust rod arranged in the draw-head and the hollow draw-bar and having its front end positively connected with the free end of the lock, preferably by engaging eyes f f, formed on these parts, as shown, and having its rear portion guided in an opening 9, formed in a standard or upright abutment G, arranged in the draw-bar. This abutment rises from the rear end of a carrierbar G, resting upon the bottom of the draw- Serial No. 626,939- (No model.)

bar and draw-head and extending forwardly from the abutment. The carrier-bar is provided at its front end with a depending stop pin or projection g, which is arranged in an opening h, formed in the bottom of the drawhead. This opening may be the same opening which is generally provided for the escape of snow and water from the chamber of the draw-head, and when that opening is so used the pin g is made sufficiently smaller than the opening to leave a discharge-passage between the pin and the opening, as shown in Figs. 1 and 3. The pin g is removably confined in its opening by a cotter g or other suitable means.

I is a spring which tends to hold the lock in engagement with the tailpiece of the knuckle and which surrounds the thrust-rod F, between the abutment G and a washerj, bearing against the eye f of the rod. The spring is under compression in the forward or normal position of the look, so as to prevent the look from being accidentally swung out of engagement with the knuckle by shocks.

Owing to the swinging movement of the lock the thrust-rod F is caused to swing laterall y on the carrier-bar G in operating the lock. The eyes ff of the lock and thrustrod form the necessary joint between these parts, and in order to permit the necessary swiveling motion of the rod in the abutment G the guide-opening g is flared toward both ends, as shown by dotted lines in the drawings.

I claim as my invention 1. The combination with the draw-head, the hollow draw-bar and the knuckle, of a lock engaging with the knuckle andpivoted to swing horizontally in the draw-head, an abutment arranged in the draw-bar, athrustrod guided with its rear portion in said abutment and having its front end swiveled to the free end of the lock, whereby the thrust-rod is capable of swinging laterally, and a spring arranged on the thrust-rod between the lock and said abutment, substantially as set forth.

2. The combination with the hollow drawbar and the draw-head provided inits bottom with an opening, of the knuckle and its look, a carrying-bar arranged within the diatw-bar and draw-head and provided at its rear end bar and the draw-head and provided at its,

rear end with an abutment and having its front end attached to the bottom of the drawhead, a thrust-rod guided in said abutment and provided at its front end With an eye engaging With the eye of the look, and a spring surrounding the thrust-rod between its eye and said abutment, substantially as set forth.

\Vitness my hand this 6th day of March, 1897.

WILLARD F. RICHARDS.
