CHARLES O. MYERS, OF YORK SULPHUR SPRINGS, PENNSYLVANIA.

CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent'No. 310,535, dated January 6, 1885.

Application filed August 13, 1884. (No model To all whom it may concern:

Be it known that I, CHARLES O. MYnRs, a citizen of the United States, residing at York Springs, in the county of Adams and State of Pennsylvania, have invented a new and useful Railroad-Car Coupler, of which the following is a specification.

In the accompanying drawings, to which similar letters of reference are made, indicating corresponding parts in the several figures, Figure 1 is a vertical sectional view of my invention. Fig. 2 is ahorizontal sectional View of the same, an d Fig. 3 is a cross-sectional view.

This invention has relation to means for coupling ears; and it consists in the construetion and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the box or chair,which is attached to the car, and B is a movable draw head within said box or chair, adapted to slide longitudinally. The draw-head B is provided with a flaring mouth, 0, in front, and with lateral apertures E in its rear portion, said apertures registering with lateral apertures or slots F of the box A. In the top of the draw-head is made a slot near the bell-mouth for the passage of the front coupling-pin, F, which also passes through a perforation, Z), of the box A. A similar slot, 0/, is made in the bottom of the draw-head below the slot a, and a perforation, b, in the bottom of the box registers therewith. When this front couplingpin is in position, its relation to the box A is a fixed one, while the draw-head moves back and forth thereon for a short distance,which is regulated bythe length of the slots ac. The rear coupling-pin, \V, is passed through perforations c and 0, made, respectively, in the top and bottom of the draw-head, and the ends of this pin project sufficiently to engage a slot, cZ, made in the top of the box, and a similar slot in the bottom of the same. It will therefore be observed that this pin has a fixed relation to the dra\ -head,while it moves with said draw-head when the latter moves in the box A.

To the pin \Vis connected the rear end of the link D,'which is permanently connected to this draw-head, the opposite draw-head being also provided with a similar link connectedthereto in like manner. Each link D is formed with a flat-pointed head, I, the edges of which are beveled, so that it will readily slide over or under the end of the link of the opposite drawhead in coupling. Each link has a pin slot or opening,c,in rear for connection with the rear pin, H, and is also provided with a front opening, 9, and with an intermediate opening, it. When the draw-heads are coupled together, each link is connected to its own draw-head and to the opposite draw-head by the front coupling-pin of the latter, so that if one pin should break the connections will be maintained by the other pins.

E indicates atransverse bar or hearing, which extends through the lateral slots E and F of the draw-head and its box A. To this bearing is connected a guide-rod, N, which extends to the rear through another transverse bar or bearing, E, and through the transverse rear wall, S, of the draw-head and through the rear wall of the box A.

On the rod N and between the bearings E and is the spring S, and on said rod between the rear walls of the draw-head and box is the auxiliary spring S". The rear spring operates to keep the drawhead from being injured by the shock of contact in coupling, and so, also, does the spring S; but this'spring also serves to allow the draw-head to be pulled outward somewhat, so that both front and rear coupling-pins will be brought to bear when the strain of the draft is on the links.

To the top of the box A is bolted or otherwise secured the spring-bar K, which is provided with upwardly-extending arms is, to which are pivoted the levers G, which are by their inner ends pivoted to the upper end 01" the front coupling-pin, F. These levers are in obliqueposition when raised, extending upwardly and inwardly, and they are held in this position by the automatic action of the spring-arm to which they are pivoted. \Vhen so held, they support the pin in disengaged position. \Vhen, however, the levers are operated to cause the pin to descend and engage the link, they take an oblique and downward ly-inclined position, in which they are automatically held by the elasticity of the springarms, so that the pin is held securely in its engaged position.

The sliding draw-head herein described and the spring-operated pin-levers can be readily ICO affixed to some of the ordinary couplingchairs now in common use. Having described this invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with a coupler box or chair, of the sliding draw-head having its lat- 3. The combinatiomwith the sliding draw- 20 head arranged within the box or chair, of the link having a front aperture 'for connection with the pin of the opposite draw-head, and a rear aperture and an intermediate aperture for connection with the front and rear pins of 25 its own draw-head, substantially as specified.

4. The c01nbination,with a draw-head, of a coupling-pin,-operating-leverspivoted thereto, and spring-arms,whercby said levers are automatically held in the raised or in the de- 0 pressed position, substantially as specified.

CHARLES O. MYERS.
