ALEXANDER C. MARTIN, OF OHIGAGQ'ILLINOIS.

CA R-COU PLING.

SPECIFICATION forming part of Letters Patent No. 502,735, dated August 8, 1893.

Application filed April 15, 1893.

To all whom it may concern:

Be it known that I, ALEXANDER C. MARTIN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in the different figures indicate like parts. i

The object of my invention is to provide a car-coupler which maybe operated with safety from the side of the car, the appliances for coupling being a hook and loop which are so constructed and arranged that the ordinary link and pin may be employed in connection therewith and adapted to cars of varying height ;all of which is hereinafter more fully described and definitely claimed.

Figure 1. of the drawings represents a vertical, longitudinal sectional View of a carcoupler embodying the features of my inventi0n,the same being shown as it appears when employed in connectionwith a link and pin. Fig. 2. is a like view showing the coupling hooks in a reverse position and likewise coupled with a link and pin. Fig. 3. is a like view showing the manner of coupling by means of the hook and loop, and Fig. 4. is a perspective view of a draw-head showing the hook therein as it appears when in its normalposition.

Referring to the drawings, a represents the usual draw-bar, integral with which is the draw-head b. The latter is open at the top and front, and within the opening, pivoted at c, is an elbow-shaped coupling device d, which is provided with a hook e, a loop f, a linksocket g, and a pin-socket h. The socket g, is arranged substantially at right angles to the hook, while the pin-socket h, is substantially parallel with the hook and at right angles or substantially so, to the axis of the socket 9.

As is obvious, the primary purpose is to dispense with the use of a link and pin whenever possible; and to use instead, the hook e, and loop f, in the manner shown in Fig. 3. The hook may be operated by means of any suitable appliance at the side of the car which will insure safety to the operator; but in case Serial No. 470.550. (No model.)

it should become necessary to connect myimproved coupler with any other form of drawbar, then the usual link and pin may be employed. If the draw-bar with which the connection is to be made is unusually high, then the hook e may be thrown down as shown in Fig. 1, in which case the body of the hook is received in a notch i, better shown in Figs. 2 and 3, formed in the face of the draw-head, which enables the outer face of the hook to be flush with that of the draw-head. By this means the hookisprotected from being broken by the impact of the draw-heads. The link j, may then be placed in the socket g and secured by placing the pin it, in the socket It. Should, however, the bar with which the coupling is to be made be lower, then the coupling device d, may be thrown back as shown in Fig. 2, when the linkj, may be inserted beneath the loop f, and the pin is, inserted through said loop and into a socket Z, formed in the bottom of the draw-head as clearly shown in Fig. 2, which socket is in vertical alignment with the inner face of the loop f.

From the foregoing it will be seen that a link-and-pin coupling may be readily made with my improved coupling device when the difference in height of the draw-bars is very great; While, at the same time, its use as a safety coupling is in no wise impaired.

Having thus described my invention, I claim 1. The combination in a car-coupler, of a coupling device consisting of a hook and loop integral with each other and pivoted within the draw-head, a link-socket formed within said coupling device substantially at right angles to the body of the hook, and a pinsocket having its axis substantially at right angles to that of said link-socket.

2. The combination with a draw-head, of an elbow-shaped coupling device pivotally mounted therein, said device having a hook upon one part and a slotted arm or loop upon the other, a link-socket therein arranged substantially at right angles to the body of the 1 3. The combination WithadraW-head, of an elbow-shaped coupling device pivoted therein having a hook upon one part and a loop upon the other,link-socketgand pin-socket h, substantially as described.

4. The combination with a draw-head open at the top and front, of an elbow-shaped coupler having a hook upon one part and a link upon another, of the link-socket g, pin-socket h, and the cut-away portion t', whereby the hook may be protected from impact while the link is used in connection with the socket g.

5. The combination with a draw-head, of a pivoted hook-and loop coupling device and double link sockets, one of which is formed in the pivoted coupling device itself and the other in the bottom of the draw-head beneath the loop, substantially as described.

6. Acar-coupler consisting of two elbows pivotally secured in oppdsite drawheads which are open at the front and top respectively, each of said elbows having a hook upon the extremity of one arm and a corresponding loop or opening at or near the extremity of the other, said elbows being provided with link-sockets therein substantially at right angles to the bodies of the hooks, pin-sockets arranged substantially at right angles to the axes of said link-sockets, and pin-sockets in the bottoms of said draw-heads in alignment with said loops, substantially as set forth.

7. The combination with a draw-head, of the pivoted coupling device d, having loop f, a space beneath for the reception of alink, link and pin sockets g h, respectively, and a pinsocket in the bottom of the draw-head andin vertical alignment either with the pin-socket h or loop f, according as said coupling device is in one or the other of its extreme positions, substantially as described. a

In testimony whereof I have signed this specification, in the presence of two subscribing witnesses, this 11th day of April, A. D. 1893.

ALEXANDER G. MARTIN.
