IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 150,407, dated May 5, 1874 application filed February 11, 1874.

To all whom it may concern:

' connected by levers when it is desired to uncouple the cars, all as hereinafter more fully set forth.

To enable others skilled in the art to make and use my improved coupling, I will now proceed to describe the same with reference to the accompanying drawings, in which- Figure 1 is a perspective view, showing my improved coupling device. Fig. 2 is a vertical sectional view, and Fig. 3 is a top plan view.-

Referring to the parts by letters, letters A A represent the ends of two adjacent cars coupled by my improved device. B B represent the draw-heads, one side of each of which has an opening or slot with an inclined face, I), in front, and a similar-shaped slot, I), in rear, the two slots or openings b I) being divided by a wall, D". is a block, C, the upper end, 0, of which projects forward, and is rounded off, as shown, at its lower forward corner, and .is vertically grooved for the reception of the latch-shaped catches, and its lower front portion 0 forms a bumper to sustain the blow from an approaching car. 7 D D are latch-shaped plates or blocks, the lower ends of which are rounded off in front and out with a right-angular notch in rear. They are also cut with vertical slots 01, and provided at their rear ends with tongues or ledges d, which fit corresponding grooves in the blocks 0 O. E is a pin or bolt passed lat- On the other side of the draw-head erally through the block 0 and slot 01 of the latch D. G G are levers pivoted on posts 9 g secured to the blocks 0 0. Their forward ends are pivoted to the'latches D D. h is a catch, also secured to the block 0, and serves to secure the lower end of the lever G when the latch is raised.

The operation of my invention is as follows: As the cars come together the rounded forward ends of the latches D D enter the outer slots of the draw-heads, and, coming in contact with the inclosed faces I) b, they will be forced upward until their points pass over the wall I), when they will fall, by their own gavity, into the slots 1), and securely hold the cars together until uncoupled by raising the latches D by forcing down the levers G. The latches thus slide up and down in the slots or grooves in the forward ends of the blocks 0 0, coupling the cars automatically. When de sired, they may be retained ,in an elevated po sition by hooking the levers Gin the catches h.

By having two latches, D D, in each drawhead it will be evident that when a car is .turned end for end it will not disarrange the coupling features. A hole may be bored in the forward end of either or both draw-heads, and a funnel-mouth be added for the purpose of coupling to the ordinary draw-headand linkand-pin couplings.

I claim 1. The latch D, having the vertical slot d and rounded and notched lower end, in combination with the grooved block 0, having bumper O, and the draw-head B, having slots 1) b, substantially as and for the purpose specified. A

2. The combination of the latch D, block (J. draw-head B, and lever G, constructed to 0p crate as and for the purpose specified.

, THOMAS ELLISON.
