UNITED STATES PATENT OF CE.

WILLIAM B. BEssnY, OF E'LMIRA, NEW YORK.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 285,787, dated October 2, 1853.

ing is a full, clear, and exact description of the invention.

The object of my invention is to furnish a device whereby cars may be'coupled together with ordinary links without danger to the persons in charge of the work of coupling the same. I attain this object by means of the mechanism shown in the accompanying drawings, in which- 7 Figure 1 is a longitudinal section of a drawhead, showing-all the parts of the device. Fig. 2 is'a cross-section, and Fig. 3iis a plan.

i In the drawings, a is the hinged draw-bar. b is a supporting-dog pivoted to a draw-bar. c is an arm at nearly right angles to and rigidly attached to b, for the purpose of throwing the latter forward when lifted out of its mortise. d is the portion of the bottom of the chamber upon which I) will rest when the draw-bar a is lifted and the link withdrawn. e is the hinge where the draw-bar a is attached to the tail of draw-head. f is an ordinary link. 9 is the draw-head.

It will be seen that the pin is connected with the hinged draw-bar in such a manner that when the pin is lifted, either by taking hold of the head of it with the hand from above or by means, of a chain extending to any desired point above-as, for instance, the top of a box-car-the hinged draw-bar and supporting-dog are also lifted, and the arm 0 being heavy and eccentric to the pivot by which I) is connected with draw-bar a, b will be thrown forward and rest upon d. In this position it will remain till tripped by forcibly inserting a link, when it will again resume the position shown in Fig, 1.

It will also be seen that when, in coupling cars, an ordinary link is inserted in one drawhead in the manner shown in Fig. 1, (it may be a straight or crooked link, owing to whether the cars be of same or different heights,)

Application filed May 26, 1882. (N 0 model.)

I and the pin islifted, so that the dog I) will rest on d, the coupling will be accomplished by simply running the cars together, even in the absence of an attendant.

The dog I), being pivoted to the draw-bar a at its upper end, and having its lower end always in position to be forced against the back wall of the mortise in the lower drawbar, forms a stop to prevent the link being forced at anytime too far back into the chamber between the draw-bars.

By a proper adjustment of all the parts the cars may be coupled closely, as in passen= ger-coaches, or loosely, as in freight-cars, so that without dispensing with the favorite and time-honored linkconnection, I have thus produced a device most simple and effective for coupling cars of any description, whereby entire convenience and safety are secured.

It will be seen that the draw-bar a in my device is not merely a factor in a pin holding and tripping device; but is, in fact, to all intents and purposes, a draw-bar and pin combined, and as a draw-bar entirely fills the office of the stationary upper draw-bar in common use. The draw-bar a is kept from being lifted too high by the stop m of the bufferhead, so that when properly adjusted the dog I) cannot be lifted out of the mortise in the lower draw-bar.

The pinh may be rigidly fastened in the draw-bar a or loosely, whichever may be preferred; but if loosely, then a collar, k, will be required.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupling, the combination of the upper draw-bar and its coaeting couplingpin J1. and dog I), with the lower drawbar, by means of a hinge or its equivalent, at any point forward of the swivel-head, in such manner as that, when the pin is lifted, the draw-bar is also lifted and held up by the dog I), substantially as and for the purposes set forth. I

2. The combination, with the upper drawbar, a, connected with the lower draw-bar by means of a hinge or its equivalent, and having the pin 71 securely fastened thereto, of a dog, b, having an eccentric arm, a, and a shoulder, 1, substantially as and forthe pufipfiaeset forth.

3. The combination of the upper and lower drawbars, the pin h, the dog b, the draw-head, and the link f, whereby the link f, when forced against the dog I), with its shoulder Zresting on d trips it and Causes the fall of the upper draw-bar, d, and the pin h, and is itself not only engaged by the pin, but is firmly clamped IO between the upper and lower draw-bars, and thus held in horizontal position.
