OAR-COUPLING.

sPEoIFIcATIoN forming part of Letters Patent No. 287,702, dated October so, 1883,

Application filed June 28, 1883. (N0 model.)

To all whom it .may concern.

Be it known that I, ROBERT T. MORRISON, J r., of Medina, in the county'of Medina and State of Ohio, have invented certain new and useful Improvements in Oar-Couplers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements 'incar-couplers; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in.

the claims.

In the drawings, Figure l is a front elevation of my new car-coupler. Fig. 2 is a vertical side viewof the same, partly in section. Figs. 3 and 4 are perspective views in detail, illustrating a manner of attaching my new coupler to an ordinary draw-head. Fig. 5 is a plan view of a guiding-loop.

A represents the front end of a draw-head,

provided with a recess that is open at the top and wide at the front end, to insure the entering of. the link. The bottom of the chamber slopes upward and the side walls slope inward toward the back end, where the chamber is only large enough to accommodate the width of the link. Near the back end, and in a central position laterally in the chamber, is the stationary draw-pin a, that is vertical (in all sides except the front side, where it slopes backward and upward, forming an incline, on

which thelink slides up over the draw-pin,

and drops over and engages the-back side thereof.

O is a frame operating vertically in grooves ain the side walls and bottom of the drawhead, and supports from the top end the pendent rod 0, to which is attached the weight D.

, The said weight may slide vertically on its support to a limited extent, and hangs in such a position that it presses against or is near the back of the draw-pin a, but may swing back to some distance from the said draw-pin. The rod '0 passes through the loop 0, that is connected with the frame 0, and serves as a guide for the said rod.

The frame '0 is actuated by means of the 5o jointed rod E, that passes through the guide d, and is pivotally attached to the lever F.

to the other end the cord or wire G, leading through a guiding-loop, g, from-whence it may lead and be operated in any direction or at any distance desired.

H is a link for coupling the cars, and may be of any of the ordinary patterns that are in use.

. The operation of the device is as follows: The coupling-link,when held at one end either by the hand'or by a draw-head, may be coupled at the other end by thrusting it into the chamber of the draw -head,where it will slide up on the incline of the pin a and push back the weight D and drop behind the said couplingpin, the weight D immediately swinging back to its former position and holding the link from disengagement with the said pin.

It will be seen that the back part of the bottom of the chamber from the front part of the pin a backward is about horizontal, so that the weight D, hanging just above the end of the link, would hold the said link in nearly a horizontal position, and will guide it into the chamber of an opposite and similar drawhead. If the opposite end of the link were depressed, it would only pry up on the weight D, and-cause it to slide up on the rod 0, and without any disengagements of the link and pin; also, the flaring shape of the said chamber gives a free lateral motion to the link beyond its requirements in actual use.

The weight D cannot slide upon the rod far enough to admit of a disengagement of the coupling-link .and draw-pin. The combinarod E forms a togglejoint, which, by the gravity of the parts, passes a straight line and rests against the car, as shown, preventing the frame 0 from being raised in any manner by the link. When it is desired to disengage the said link and the said pin, it .may be done by pulling on the cord G, which, by means of the lever F and the rod E, will raise the frame 0, which, in turn, will raise the link above the pin a and entirely disengage the said'link. When one end of the link is disengaged or uncoupled, the engagement of the other end of the link with the opposite draw-head holds the link in nearly a horizontal position and ready to again enter a draw head and be tion of the lever F and the upper part of the coupled. Of course, the chamber might be covered, except so much of the space as is necessary for the operation of the frame 0 and the weight D.

The back side of the draw-pin a may be faced with iron or steel in such a manner that the facing may be renewed when required and protecting the pin proper from all wear.

In Fig. 3 is shown a manner of attaching the new device to an old draw-head. Fig. 4 is a view in perspective of a part of the new draw-head adapted to be attached to an old draw-head, as shown in Fig. 3.

\Vhat I claim is- 1. The frame 0, provided with the guidingloop 0, and suitable mechanism adapted to raise thelink above the draw-pin, substantially as shown and described.

2. The combination, with the frame 0, rod 0, and weight D, of a draw-head provided with a rigid pin, a, substantially as set forth.

3. The eombination,with the draw-head having a rigid pin, a, of the frame 0, provided with the loop 0, the weight D, and devices for elevating the frame, substantially as set forth.

4. The combination of the jointed rod E and the lever F, adapted to prevent the frame C from rising except by the direct action of the lever, substantially as shown and described.

In testimony whereof I sign this speeifica- 30 tion, in the presence of two witnesses, this 2d day of June, 1883.
