QPECIFICATION forming part of Letters Patent No. 303,054, dated August 5, 1884.

To all whom it may concern.-

Be it known that I, PATRICK RYAN, of Guelph, Province of Ontario, Canada, have invented a new and Improved CarOoupling,

5 of which the following is afull, clear, and exact description.

This invention consists in the combination, with a draw-head, of acoupling-hook pivoted in the same, and a transverse bar held under the draw-head and connected with a bar having the outer end pivoted to the car and the inner end pivoted to the transverse bar, the inner end of the pivoted bar being connected with a spring for pulling or pressing it up- I 5 ward, and pressing the coupling-hook up into the draw-head.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l. is a longitddinal sectional elevation of my improved car-coupling, two cars being shown coupled. Fig. 2 is an end View of the same, and Fig. 3 is a plan view of the under side of the same.

In the inner end of the draw-head A the forked front end, B, of the spindle O is held, which passes through the inner end crosspiece of the draw-head and through two plates, D, on the under side of the car, and which spindle is surrounded by'a spiral spring, E,

between the plates 1). The draw-head A is held in place by supporting-clips F, secured to the bottom edges of beams G, between which the draw-head is located. In the fork B of the spindle O the inner end of a vertically-swinging couplinglink H is pivoted, and

on the inner surfaces of the sides of the draw head guide-lugs J are formed, between the in- 40 nor edges of which the coupling-hook'passes. The drawhead is provided in its top with a slot, I, for the prong of thehook H. A bar, K, has one end pivoted to a shackle or clip, K, on one side of the end of the car, and its free inner end is pivoted to a transverse bar, L, under the draw-head. A spring, M, secured to the bottom of the car, projectstoward the end of the same, and its free end is connectedby a link, M, with the middle of the bar K. The ends of the bar L rest againstthe shoulders or clips K on the end of the car.

On that end of the bar L opposite the one at which the bar K is located the free end of a lever, N, is held, which is pivoted to the bottoin of the car, and extends toward the end of 5 5 the same, and from the free end of the lever N a rod, 0, extends upward, which is guided on the end of the car. The coupling-hook H isprovided at its free endwith a lug, P, on each side for supporting the link It.

The operation is as follows: Il'a link is held in one draw-head and the draw-heads come together, the entering link forces down the prong of the coupling-hook in the tl1'dW-llCLd, which it enters, and then passes over the prong and catches on the same, whereby the cars are coupled automatically. As the coupling-hook is pressed down, it presses down the bar L, and when the link has passed the hook the spring Mforces the bar L upward. If the cars are to be uncoupled, either end of the bar L is pressed downward, thus permitting the coupling-hook to drop, whereby the link is released. If one end of the bar L is pressed down the other end restsagainst the opposite shackle, K, and as soon asthe bar L is released it is thrown up by the spring M. The bar L can be moved downward from the carplatform by means of the red O. The drawhead must be open on the bottom, or provided with a longitudinal slot, to permit the coupling-hook to swing down.

The abovedescribed car-coupling can be used on freight or passenger cars. The drawheads are in no way fastened to the levers for uncoupling, and thus if the draw-heads come in contact or strike together they cannot break or bend the levers or like parts,

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a car-coupling, the combination, with a draw-head, of a coupling-hook pivoted in the same, a transverse bar held under the drawhead, a bar pivoted to the middle of said bar, and of a spring for pressing the bars upward, substantially as herein shown and described.

2. In a car-coupling, the coinbination,with the draw-head A, of the pivoted couplinghook II in the same, the bar K, pivoted to the car, the transverse bar L, pivoted to the inner [00 end of the bar K, the spring M. on the bottom of the car, and of the link M, connecting the free end of the lever K with the spring M, 4.

In a car-coupling, the combination, with the draw-head, the coupling-hook H, pivoted I 5 the draw-head A, of the pivoted couplingin the fork B, and the spring E, surrounding 5 hook H in the same, the transverse bur L unthe spindle G, substantially as herein shown der the draw-head, a spring, M, for pressing and described. it'against the under side of the draw-head, the lever N, pivoted to the under side of the our, I PATRICK RYAN, and connected with the bar L, and of the rod IO 0, extending upward from the free end of the WVitnesses:
