DAVID LAVSON RICHARDS, OF ST. JOHN, NEV BRUNSVIOK, CANADA.

CARHCOUPLING.

SPECIFICATION forming part o Letters Patent No. 311,528, dated February 3, 1885.

Application filed Novcmbcrl, 1884. (No model.)

To @E5 whom, it may concern:

Be it known that I, DAvrD Lawsonv Rien- ARDS, at present residing in St. John, in the Irovince of New Brunswick, of the Dominion of Canada, have invented a new and useful Improvement in Railway-Car Couplings; and I dohereby declare the same to be described in the following specication and represented in the accompanying drawings, of which- Figure 1 is a vertical and longitudinal section, and Fig. 2 is a horizontal and longitudinal section, of the draw-bar provided with my invention, the nature of which is defined in the claims hereinafter presented. Fig. 3 is a side view ofthe shackling-pin, its latch, and linkholder.

In such drawings, the draw-bar A is shown as having in rear of its tlaring or trumpet mouth a a recess or chamber, b, having its bottom inclined in manner as represented at c, such inclined bottom being for the couplinglink B to rest on in order to bring such link into a proper' position for coupling with another draw-bar.

The coupling-pin (shown at O) has extending rearward from it a projection, d, which Iterm the link-holder, such projection, when the pin is down through the link, being to rest ou such link and hold it in its position on the inclined plane c. In the draw-bar head there is, in rear of the shackling-pin passage ,f, another passage, g, which is for the projection d, and a spring-latch, 7i, extending down therefrom to pass through.

ln raising the pin to the position as shown by dotted lines, the latch springs forward and rests 0n the inclined plane c, and in so doing holds the pin elevated. On the link be ing forced into the chamber or recess b and against the latch, the latter will be crowded oft' the inclined plane, so as to allow the pin to drop and shackle the link to the draw4bar.

At the back of the chamber b there is an auxiliary bunter, E, to play longitudinally in the draw-bar against a spring, F, arranged therein. This bunter is furcated, so as to span the latch and not interfere with its movements, and is for the link to bring up against in or der for the draw-bars to meet together, when necessary.

To lift the coupling-pin, there is a chain, G, attached to its head, and there is also a supplementary chain, II, which is also connected to the head of the pin and to the draw-bar. This latter chain is not o'hly to determine the height to which the pin is to be raised, but to prevent it from being pulled out of the drawbar.

To set the link of one car for coupling with the draw-bar of another car, the shackling-pin is to be dropped to extend through the link and cause the link-holder to rest thereon and holdV it in an inclined position on the bottoni ofthelink-chainbcr. Theshacklingpinofthe draw-bar to receive the link, on the cars coming together, is to be raised, so as to cause its latch to rest on the inclined plane below it. On the link being driven into the said drawbar the latch will be forced backward off the inclined plane, and the lshackling-pin will drop through the link and shackle it to the draw,- bar.

From the drawbar there extends downward a projection, I, which is grooved or ehambered vertically, so as to surround the latch when it is down, such projection being to serve as a guard to prevent the latch, when down, from being accidentally struck, injured, or bent by any object.

I do not claim a car-coupling constructed as represented in the United States Patent No. 106,936, as such has in its draw-bar, as there is in mine, no chamber provided with an inclined bottom to centraline the coupling-link or hold it in an inclined position, with its outer end level with the axis of the chamber or draw-bar, nor has the patented coupling any furcated auxiliary bunter to span the coupling-pin and be struck by the link when passing into the aforesaid chamber; nor is there to the catch a spring connecting it with the pin, as in my coupling, or any grooved projection extending below the draw-bar and for guarding the catch from injury. Therefore it will be seen that there are important differences between my coupling and that of the said patent.

I claiml. The draw-bar having in rear of its ilaring mouth the chamber provided with the inclined bottom, and also having passages for the shackling-pin, its link-holder., and latch to move in, in combination with the shacklin g-pin provided with such holder and latch,
