IMPROVEMENT IN CAR-COU PLINGS.

Specification forming part of Letters Patent No. 43, l 75, dated June 21, 1864.

To all whom it may concern:

Be it known that I, JOHN S. BELL, of Hackettstown, in the county of Warren and State of New Jersey, have invented a new and Improved Oar-Coupling; and I do hereby declare that the following is a full, clear, and. exact description thereof, which will enable others skilled in'the art to make and use the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side sectional view of my invention, taken in the line at m, Fig. 2. Fig. 2 is a horizontal section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate like parts.

This invention relates to a new and improved car coupling of that class which are commonly termed self-coupling, and it consists in a novel arrangement of parts for keeping the link or shackle in aproper position forentcring the draw-head of an adjoining car; and it further consists in a novel arrangement of a pin and slide arranged in such a manner that the slide will sustain the pin when the former is raised, and the slide be capable of being forced back by the entering link of the draw-head of an adjoining car, so that the pin may drop within the link and form a connection, as hereinafter set forth.

A represents a draw-head, which may be of rectangular form and secured in the usual or in any proper way to the car. On the top of this draw-head, near its front end, there is a vertical tube, B, in which a pin, 0, is fitted and allowed to work freely up and down; and D is a slide which works in grooves or guides on at the under side, I), of the top plate of the draw-head, said slide having a pendent bar, E, attached to it, which extends down nearly to the bottom 0 of the draw-head, and has a roller, 0?, at its lower end, which rests upon the bottom 0.

F is a spring, which bears against the back end of the slide D, and has a tendency to keep said slide shoved forward underneath the tube B, and the pendent bar E against a block, G, on the bottom 0 of the draw-bar, as shown in red in Fig. 1.

H is a shaft, which passes transversely through the draw-head A and directly over the block G. This shaft H has an arm, I, attached to it, which projects forward in a recess, (1, in the top of the block G, and has a notch, 0, made in it to receive one end of a link or shackle, I which is retained in the notch e by a spring, J, attached to the shaft H, as shown clearly in Fig. 1. This shaft H is allowed to turn freely in its bearings, but is retained at any desired point by a spring, K, which bears against a crank, L, at one end of the shaft. (Shown in Fig. 2.)

From the above description it will be seen that when thepin O is raised above the slide D the spring F will force the slide underneath the tube B and hold up the pin, and When the link or shackle I of the draw-head of an adjoining car enters the drawhead containing the elevated pin 0, the entering link or shackle will strike the pendent bar E and force the slide D so that the pin will drop within the link orshackle and rest in a step, f, in the top of the block G.

The link or shackle which connects the two draw-heads, it will be understood, is secured at one end in one of the draw-heads by the notch aim the arm I in said draw-head, while the opposite end of the link is secured in the other draw-head by its pin C.

By turning the shaft H the outer end of the linker sh tCklG in one draw-head may be raised or lowered to suit the height of the draw-head of an adjoining car, and thereby insure the entering of the link. This. is essential, as cars vary materially in height, and unless some provision be made for the variation a connection could not in many instances be effected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The slide D, with pendent bar E attached, in combination with the spring F, block G, pin 0, and link or shackle I, all arranged substantially as and for the purpose herein set forth.

2. The shaft H, with the arm I attached, provided with a notch, e, the spring J, for holding the link or shackle in the notch, and the retaining or holding spring K, or its equivalent, substantially as and for the purpose set forth.

JOHN S. BELL.
