CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 289,002, dated November 27, 188?.

Application filed September 526, 1883.

f0 aZZ whom it may concern.-

Be it known that 1, Isaac HOLLAND, a citizen of the United States, residing at St. Peters, in the county of St. Charles and State of Missouri, have invented a new and useful Car- Coupling, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to car-couplers, the object being to provide a coupler of cheap and durable construct-ion, and one that shall be thoroughly effective and certain in its operation.

A further object of the invention is to provide improved devices for uncoupling the cars.

The invention consists in the improved construction and combinationsofparts,hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a car with my improved coupler applied thereto. Fig. 2 is a longitudinal vertical section of the same, and Fig. 8 is a detail perspective view of my improved devices for uncoupling the cars.

A represents the front end of a car, which is cut to receive the bumper B. This bumper B extends longitudinally through the cut-away portion of the car, its rear end beari'ng against a beam or brace, a. The rear end of the coupler is cut away and forms a shaft, a, upon which is mounted a coil-spring, b, which bears against the end 0 of the bumper at one end and against the beam or brace a at its other end. This spring acts as a cushion and prevents the jarring incident to the coupling operation.

0 represents the draw-head, which is provided with the usual flaring mouth, (I.

The upper or top portion of the bumper is cut away its entire length, to receive the coupling-latch D. This coupling-latch is pivotally secured in the longitudinal recess of the bumper, and is beveled at its forward end and formed with a notch, c, to receive and retain the coupling-link.

latch D is provided a coil-spring cl, one cut of which is secured to the latch 1), whiletheother end rests in the recess of the bumperQ This spring serves to keep the forward end of the latch in close contact with the bottom of the draw-head, and prevents the disengage. ment of the coupling-link.

'of the lateral movement of the lever.

At the rear end of t (No model.)

E represents a pulley mounted on a shaft which is secured to the front of the car directly above the bumper. This shaft 6 is provided with a flange, 6 to prevent the chain c" from becoming disengaged.

F represents a lever mounted on a shaft, f, at the front end of the car. This lever F is provided with a forked lever, F, which is pivoted thereto. The lever F is formed with a slot, f and the lever F is provided with a pin,f, which is secured to the two arms of said lever. The pin works in this slot and serves to limit the forward or rearward movement of the lever F. One end of the chain a is secured to the coupling-latch D, and from there extends over the pulley E, the other end being secured to the lever F.

G represents a block secured to the upper or top part of the car, and is grooved to allow The lever F is provided at its upper end with a slot, g, adapted to engage the teeth 9*, formed on the inner side of the block G.

The operation is as follows: hen the cars are to be uncoupled, the car carrying the link is brought in contact with the car to be coupled, the link is striking against the beveled forward end of the latch, which depresses the spring (1, thus causing the latch to be lifted. The end of the link then enters the notch in the latch D, and is securely held therein against forward or rearward movement. As soon as the link enters this notch in the latch, the latch is forced into its normal position by means of the spring d. hen the cars are to be uncoupled, the lever F is moved laterally and the latch raised by means of the chainconnection. The lever F is then pushed forward, this movement being allowed byits pivotal connection with the lever F, the pin working in the slot limiting the movement of the lever F, and the slot 9 engaging one of the teeth of the block G, and in this manner the latch is held from engagement.

' H H represent bars or rods, the rear ends of which are secured to the brace 0. Their forward ends extend through slots h h in the front end of the car, their ends being notched or cut away to receive and retain a chain.

I I represent handles loosely secured to the top of the car, and provided with hooks i i at their lower ends. These bars H H serve as an auxiliary coupling in the event of the automatic coupling becoming broken or out of working order, the cars being coupled by chains which are placed in the notches by means of the hooked handles I I.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the bumper 1-3, provided with a shaft having a spring, b, mounted thereon, and a brace, a, of a pivoted latch, D, having the notch c, the spring (1, and a pivoted lever, F, connected to said latch by a chain, c, substantially as set forth.

2. The combination, with the bumper B and pivoted latch D, of the lever F, having a
