CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 354,677, dated December 21, 1886,

Application filed April 27, 1886. Serial No. 200,285. (No model.)

To all whom it may concern:

Be it known that 1, JOHN BERSOH, of Kingston, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in Oar-Couplings, of which the following is a full, clear, and exact description.

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

Figure 1 is afront elevation of a part of a car to which my improved coupling has been applied. Fig. 2 is a sectional side elevation of the same, taken through the line a m, Fig. 1, and showing the end of a coupling-bar ready to enter the draw-head. Fig. 3 is a sectional plan view of a part of the same, taken through the'line y 3 Fig. 1. Fig. 4 is a front elevation of a part of a car, showing a modification of the mechanism for uncoupling the cars.

A represents the-frame, and B the bumpers, of an ordinary freight-car. .O is the draw- I head, which is secured to the frame A in the usual manner.

The top and bottom of the mouth of the drawhead 0 are flared or beveled in straight lines, as shown in Fig. 2.

The draw-head O has a transverse perforation, D, at its throat to receive the horizontal coupling-pin E, which slides in a support, F, attached to the car-frame, and is held forward by a spiral spring, G, placed upon it. The outer end of the spring G rests against the support F, and its inner end rests against a collar, H, formed upon or attached to the said coupling-pin E. The outer end of the pin E is connected with the lower end of a lever, I, by a link or other suitable coupling.

The lever I is pivoted to the car-frame A, and its upper end extends into such a position that it can be readily reached and operated to uncouple cars. The lower part of the lever I moves in a keeper, J, attached to the carframe A, which keeper has a recess, K, at its outer end to receive the lower end of the said lever I and fasten the said lever in place when the pin E is drawn outward, so that cars can be run together without coupling.

If desired, the lever I can be omitted, and one end of a short chain, L, attached to the outer end of the pin E. The other end of the chain L is attached to and wound upon ashort shaft, M, journaled in supports N, attached to the car-frame and operated to wind the chain L upon it by a crank or key applied to the outer end of the said shaft, but which key is not shown in the drawings. To the shaft M is attached a ratchet-wheel, O, with the teeth of which engages a pawl, P, pivoted to the frame A, to hold the coupling-pin in place when drawn out. When the pawl]? is raised from the ratchet-wheel O, the coupling-pin E is forced forward by the spring 1 G, hereinbefore described.

Q is the coupling-bar, the ends of which are beveled upon their upper and lower edges to cause them to enter the mouths of draw-heads O readily, and have each a perforation, R, formed through them to receive the couplingpins E.

Inclined shoulders S are formed upon the upper and lower edges of the draw-bar Q, a little in the rear of the perforations R, and in such positions as to fit snugly against the in clined tops and bottoms of the mouths of the draw-heads 0 when the coupling-pins E are in place, so as to take the strain of the jar when the cars are run together, and thus relieve the said coupling-pins E from the said strain. The inclined shoulders S of one end of a draw-bar, Q, fitting against the inclined top and bottom of a draw-head, 0, cause the coupling-bar to be supported in a horizontal position, sothat two which passes transversely through the draw head and through a recess, W, in the upper side of the said block T, the said recess being made of such a length as will allow the said block to have the necessary amount of movement.

The recess W and the pin V are so arranged that when the block T is at the limit'of its forward movement the sides of the outer end of IOO the block T will cover the inner ends of the pin-hole D, so that the said block will hold the coupling-pin from being pushed inward by the spring G.

With this construction when two cars are run together the coupling-bar Q of one car will enter the draw-head of the adjacent car and strike against and push back the guardblock T, allowing the spring G to push the coupling-pin E through the perforation R of the draw-bar Q and couple the cars.

The draw-head G has a vertical perforation, X, formed through it to receive the couplingpin, so that an ordinary link-andpin coupling can be used when necessary. In this case the inner surface of each of the sides of the drawhead 0 has a horizontal groove, Y, formed in it. These grooves receive the coupling-link,

so that the link will be held in a horizontal position by the pressure of the guard-block '1 while cars'are being run together.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 7 1. Inacar coupling,the coupling-bar Q,made

the draw-head 0, having the top and bottom of its mouth flared in straight lines and provided with a transverse perforation, of the coupling-bar Q, having upon its upper and lower edges inclined shoulders to fit against the inclined top and bottom of the draw-head mouth, the coupling-pin E, held forward by a spring, G, and a pinWithdrawing mechanism, 40 substantially as herein shown and described.

JOHN BERSOH.
