CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 461,043, dated October 13, 1891.

Application tiled May 29, 1891. Serial No. 394,577. (No model.)

.To all whom, t may concern:

Be it known that we, GEORGE ANDERSON PATTEN and JOHN 'lHoMAs WEBBER, citizens ot' the United States, residing at Red Lodge,

in the county of Park and State of Montana, have invented a new and useful CarCoup ling, ot' which the following is a specification.

The invention relates to improvements in carcouplings- The object of the present invention is to provide asi mple and inexpensive car-coupler which will be automatic in its operation and which will uncouple should a car be overturned or derailed, and which may be readily uncoupled without necessitating a person passing between the cars.

The invention consists of the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View ot' a car-coupling embodying the invention. Flg. 2 is a vertical longitudinal sectional view. Fig. 3 is a reverse plan view.

Referring to the accompanying drawings, 1 designates a car having horizontal sills 2, between which are arranged a draw-bar 3, and the latter is provided at its front end with an integral coupler-head 4. The drawbar has its rear end connected to the ends of a metal stirrup 5, and interposed between cross-plates (j is a spiral sprin g 7, which is arranged on the rod 8. The crossplates are arranged within the stirrnp and between the sills 2, and the spring forms a cushion to prevent shocks in coupling and jars incident to the passage of a train. The-plates are limited in their movements by stops 9 and 10, which are formed by plates secured to the inner opposed faces of the sills and having their adjacent ends bent at an angle. When cars come together in coupling, the spring bears against the rear plate, and duringthe passage of the train, when the draw-bar is drawn outward, the spring bears against the front plate. By this arrangement a perfect spring-cushion is formed.

The coupler-head is provided -in its lower face with a cavity or recess 11, which has its front walls shouldered and adapted to engage heads of a link 1.2, and acting in conjunction with the coupler-head is a plate 13, which is arranged adjacent thedraw-bar and is provided with an opening 11 to receive a depending lug 15 of the draw-bar, and the 55 bottom plate 13 is secured in place by crossplates 16 and the said lug 15. The outer or front end of the bottom plate is bent downward and is adapted to guide the link 12 into the recess 11. The link 12 is provided at its 6o ends with heads 17, which are beveled toward the ends of the link andare shouldered at 1S, and are adapted to engage the shouldered wall ot' the recess 11.

The cars are uncoupled andthe couplerhead raised to release thelink byarock-shaft 19, which is provided intermediate its ends with a rectangular bend 20, arranged in a recess 21 of the draw-bar and adapted to engage the same to lift the coupler-head. The 7o ends of the rock-shaft are bent at an angle, and the outer end 22 is connected by a chain 3 with a lever2t. The lever24; is fulcrumed on the side of the car a-nd is arranged in the. ratchet 25, and is provided with a flanged segment 26, on which the chain is wound to turn the rock-shaft.

1n the accompanying drawings the carcoupling is shown applied to a box car; but it is equally applicable to a passenger and 8o other cars, and we desire it to be understood that we do not limit ourselves to the precise details of construction herein shown and described, as we may, without departing from the spirit of the invention, make minor changes therein.

1t will be seen that the car-coupling is simple and inexpensive in construction and automatic in operation and adapted to be readily uncoupled without necessitating a person 9o passing between the cars.

The rock-shaft is journaled in suitable bearings in an L-shaped plate 27, arranged on the side of the car adjacent the lever. Asuitable stop is provided to prevent the loop or bend of the rock-shaft being thrown forward beyond the perpendicular.

lVhat we claim is- 1. The combination ot' a car,the verticallymovable coupler-head provided with a recess roo in its lower face adapted to receive a headed link, a bottom plate arranged beneath the coupler-head, and a rock-shaft having an arm' arranged to engage the coupler-head and lift the same, substantially as described.

2. The combination of a car provided with parallel sills 2, the vertically-movable drawbar having a coupler-head which is provided with a recess to receive a headed link, the bottom plate arranged beneath the draw-bar and between the sills and provided with an opening, the cross-plates 16, secured to the sills and retaining the bottom plate in place, and a lug depending from the draw-bar and engaging the opening in the bottom plate, substantially as described.

3. The combination of acar, a verticallymovable coupler-head having a recess in its lower face adapted to engage a headed link,

the bottom plate arranged beneath the coup- `1er-head, the rock-shaft arranged to engage GEORGE ANDERSON PATTEN. JOHN THOMAS WEBBER. A
