CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 515,185, dated February 20, 1894.

Application iiled April 20, 1893. Serial No. 471,108. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, SAMUEL G. WILBER, a citizen of the United States, residing at Lake Hill,in the county of Ulster and State of New York, have invented a new and useful Car- Coupling, of which the following is a specification.

The invention relates to improvements in car couplings.

The object of the present invention is to improve the constructionl of car-couplings and to providea simple and inexpensive one which will couple automatically, and which may be readily uncoupled without going between cars.

The invention consists in 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 l is a perspective view of a car-coupling constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a plan view of the car coupling. Fig. 5 is a detail view of the spring actuated block.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates a draw-head, having a longitudinal link-opening in which is mounted a spring-actuated block 2, provided with a longitudinal opening 3 and adapted to be engaged by a link 4, when cars come together for coupling to cause a spring-actuated couping-pin-carrying arm 5 to be tripped.

The spring-actuated coupling-pin-carrying arm has a coupling-pin 6 connected with its front end and its rear end is mounted on a transverse pin 7, which is arranged in ears 8, extending upward from the top of the drawhead, near the back thereof. The rear end of the spring-actuated arm 5 is provided with a shoulder 9, which is engaged by one arm 10 0f a spiral spring ll; the arm .l0 is formed by extending one end of the spiral spring, and an arm 12, for engaging the draw-head, is formed by extending the other end of the spiral spring. The spring-actuated arm 5 is provided with a depending heel 13, arranged below the transverse pin 7, and adapted to be engaged by the upper end of a trip-lever 14,

which is fulcrumcd on a transverse pin 15, and which has its lower end arranged in the opening of the spring-actuated block. The upper end of the lever is arranged in advance of the heel of the spring-actuated arm and is recessed to be engaged by the front edge of the heel and is adapted to maintain the springactuated arm in an elevated position to hold the coupling-pin in position preparatory to coupling. When the link enters the drawhead for coupling it engages the spring-actuated block and moves the upper end of the trip-lever out of engagement with the heel of the spring-actuated arm, thereby permitting the spring to cause the arm 5 to descend. As soon as the spring-actuated arm is raised, the block engages the lower end of the lever and moves the same forward, thereby carrying the upper end of the lever rearward in engagement with the heel of the spring-actuated arm to maintain the latter in elevated position. The follower block has its front face or end concavely recessed, and it is actuated by a spiral spring 16, arranged in rear of it and engaging its rear end.

It will be seen that the car-coupling is simple and inexpensive in construction, automatic in operation, and does not necessitate persons going between cars.

The front end ofthe spring-actuated arm is provided with an eye, and any suitable means may be provided for enabling the coupling-pin to be elevated from the sides and top of a car.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. y

The curved recess at the front end of the follower block is adapted to engage the adjacent end of the link 4 with sufficient pressure to hold the link in any desired position for coupling to enable the link to readily enter the draw-head of an approaching car.

What I claim is- 1. In a car coupling, the combination of a draw-head, a coupling pin, an arm hinged at its rear end to the draw-head and arranged on top thereof and provided with a depending heel and having its front end connected to the coupling pin, a spring-actuated block mounted in the draw-head and provided with IOO a longitudinal opening, and a trip-lever fulcrumed on the draw-head and having its upper end engaging the heel of said arm and having its lower end loosely arranged in the opening of the spring-actuated block, substantially as described.

2. In a car-coupling, the combination of a draw-head, a coupling-pin, ears rising from the draw-head, a transverse pin arranged in the ears, an arm having its rear end mounted on the pin and provided with a depending heel and having its front end connected to the coupling-pin, a spiral spring mounted on the transverse pin and engaging the arm, a

having its lower end arranged in the opening of the block and its upper end provided with a recess to engage the yheel of said arm, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

SAMUEL G. WILBER.
