FREDERICK SLOAT, OF CHICAGO, ILLINOIS, ASSIGN OR OF ONE-HALF TO MARTHA W. PERKINS, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 281,935, dated fu-ly 24, 1883.

Application filed April 4, 1883. (No model.)

To all whom t may concern/:-

Be it known that I, FREDERICK SLOAT, of Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Automatic Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specication.

My invention relates to an improvement in automatic car-couplings; and it consists in the combination of a stationary pin, by which the link is held in position, a spring-actuated block against which the rear end of the link bears, y

and a pivoted automatically-acting pin, which is pivoted inthe draw-head near its outer end, and which is provided with a crank by which it can be moved by hand, as will be more fully described hereinafter.

The object of my invention is to produce an automatic car-coupling, whichis designed to be used upon cars of all kinds, and which is so constructed that it can be operated from the platform on the top of the car or from one side without the necessity of the brakemen going between the cars, and thus endangering life and limb.

Figure 1 is a vertical section of a coupling embodying my invention. Fig. 2 is a horizontal section o'f the same.

A represents the draw-head, which may be ofthe shape here shown, or any other that may be preferred, and which has the stationary pin B passing vertically through it near its rear end. This pin catches in th'e inner end of the coupling-link C, while it allows the link to play back and forth, and prevents the link from being drawn from the head. For the purpose of preventing this link from being broken and bent there is a spring-actuated block, F, placed in the rear end of the draw-head, and this block 4 5 bears against the rear end ofthe coupling-link,

so as to keep it constantly pressed forward, ready to couple with another car. When the outer end of this link strikes against a solid body, the link is forced backward into the coupling until its outer end is flush with the draw- 5o head, and then as soon at the pin is left free to move, the spring-actuated block forces it out into position again.

Passing horizontally through the draw-head from side to side is the pivotal pin or bolt H; which has one or both of its ends formed into an operating-crank, I. Placed between this pivotal bolt or rod is the swinging couplingpin J, which moves back as the link from the other car enters and then immediately drops 6o back into position, so as to catch inside of the link in the usual manner. To the crank upon the end of the pin may be fastened wires, ropes, orchains, which will lead up to the top of the car or to the platform. This crank is also adapted to be moved by any person standing on the side of the car, so that a person can operate this coupling-pin, and thus free the cars from each other.

It will be seen that one link is always held 7o in position in each draw-head, and that when two cars run together th ese links enter the opposite head, and are coupled simultaneously.

Having thus described my invention, I claim- In a car-coupling, the combination of the draw-head having the stationary pin passed down through it for the purpose of connecting a coupling-link to the draw-head, the springactuated block which is placed back of this pin, and a swinging coupling-pin, which is pivoted near the front end of the draw-head, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK SLOA'I.
