SPECIFICATION forming part of Letters PatentNo. 278,880, dated June 5,1883,

Application filed March 7, 1883.

To all whom it may concern:

Be it known that I, A. lVELLs CASE, of South Manchester, in the county of Hartford and State of Connecticut, have invented a new and use ful Improvement in Automatic Gar-Couplings, of I which the following is a full, clear, and exact description.

Referenceis to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation, partly in section, of my improvement uncoupled. Fig. 2 is a side elevation of the same coupled. Fig. 8 is a front elevation of one coupling-head. Fig. 4 is a plan view of the two coupling-heads uncoupled.

The object of this invention is to promote convenience and security in the use of car couplings.

The invention consists in a car-coupling constructed with coupling-heads having their sides beveled to adapt them to overlap each other, and in unequal-armed U shaped coupling-rods having curved bars attached to the ends of their long arms, to adapt the said rods to be turned to couple the cars by the coupling-head of an adjacent car when the cars are run to' gether, as will be hereinafter fully described.

A represents the heads of the coupling, each of which is made with one or more months. The sides of the coupling-heads A are beveled, as shown in Fig. 4, leaving the forward parts of the said sides open, as shown in Figs. 1 and 2, the remaining or rear parts of the said sides serving as guides to center the coupling-heads upon each other. \Vith this construction, when two cars are run together, the upper part of the coupling-head A of the lower car will pass between the upper and lower parts of the coupling-head A of the higher car, the cutting away of the sides of the coupling-heads allow ing the said upper and lower parts to overlap sufficiently to bring the pin-holes B into line with each other, as shown in Fig. 2.

C are the coupling-rods, which are bent into U shape, with one arm so much longer than the other as to pass through the couplingheads A, while the ends of the short arms rest upon the upper sides of the said coupling heads, as shown in Figs. 1, 2, and 3.

To the lower ends of the long arms of the (No model.)

I coupling-rods C are rigidly attached the ends of curved bars D, which project about at right angles with the planes of the said couplingrods, as shown in dotted lines in Fig. 4, the convex sides of the said curved bars 1). being toward the short arms of the said rods 0.

In the upper sides of the coupling-heads A are formed grooves E F, to receive the ends of the short arms of the ,coupling-rods O, and which are curved in the arcs of circles having their centers in the axes of the long arms of the said coupling-rods. The curved grooves E terminate at the pin-holes B, so that'the ends of the short arms of the coupling-rods,

readilypass into the said coupling-holes. The curved grooves F terminate in a shoulder at the side of the coupling-holes B, so that the short arms of the coupling-rods 0, when their ends are resting in the said grooves F, will not be liable to be jarred into the couplingholes B. With this construction, when the cars are to be coupled, the coupling-rods G are raised and the ends of their short arms are placed in the grooves E, which brings the curved bars D into the position shown in Fig. 4, so that when the cars are run together the lower jaw of the lower coupling-head A will strike the curved bar D of the higher coupling-head A and push it back, turning the coupling-rod 0 upon its long arm as a pivot and swinging the short arm of the said rod forward. As the short arm of the coupling-rod 0 comes to the hole B it drops through the said hole and couples the cars.

\Vhen the cars are to be run together without coupling, the coupling-rods C, when raised, are turned in such a direction that the ends of their short arms will rest in the grooves F,

ward position, so that they will not be struck by the jaws of the coupling-heads when the cars are run together.

When it is desirable to uncou'ple the cars from their tops, the endsof chains G are attached to the bends of the rods 0 at points directly over or near their short arms, as shown in Figs. 1, 2, 3, and 4. The other ends of the chains G are secured to the tops of the cars. lVith this construction, when the chains G are pulled upon, the coupling-rods C will be raised, withdrawing their short arms from the holes when moving along the said grooves IE, will which brings the curved bars D into a.rear- B, and then swinging the said rods 0 around upon their long arms, so as to bring the points of the said short arms over the grooves E or F, according to the direction in which the said chains are drawn.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A car-coupling Constructed substan ially as herein shown and described, and consisting of the coupling-heads having beveled sides, and the unequal-armed U-shaped coupling rods 0, having curved bars D, attached to the ends of their long arms, as set forth.

2. In a car-coupling, the coupling-rods 0, made, substantially as herein shown and described, with unequal arms, and with curved bars D, attached to the ends of their long arms, to adapt the said rods to be turned to couple the cars by the couplinghead of an adjacent car; as set forth.
