- CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 252,197, dated January 10, 1882. Application filed November 12, 188k (No model.)

To all whom it may concern Be it known that I, ROBERT H. DOWLING,

' of Newark, in the county of Licking and State of Ohio, have invented a new and Improved Oar-Coupling, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved car-coupling of simpleconstruction, and which can be operated without endangering the life or limb of the operator.

The invention consists in a draw-head provided with a segmental aperture extending from top to bottom and adapted to receive a segmental coupling-pin attached to an arm swinging on a pintle in the center of the circle of the segmental aperture, which arm is provided with top and bottom extensions. A guide-frame provided with elongated side loops and crank handles is loosely mounted on the ends ofthe transverse pintle, and is used to raise and guide the link.

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

Figure 1 is a longitudinalelevation of two draw-heads provided with my improved coupling, one of the draw-heads being shown in section on the line 3 3 Fig. 2. Fig. 2 is aplan ot' the same on the line mm, Fig. 1, one of the draw-heads being shown in section.

The draw-head A is provided with a central end recess, B, for the link B, and is further provided with a slot, 0, in the upper surface, and with a segmental aperture, D, extending from the top to the bottom of the drawhead, the middle of the curve being nearest the end of the draw-head.

A circularly-bent or segmental coupling-pin, E, is attached to an arm, F, which is loosely mounted on a pintle, G, passing transversely through the draw-head on the center line of the circle of which the curved aperture D is a segment, so that the segmental coupling-pin can swing on this pintle into this segmental aperture. The arm F is provided with an ex tension, H, above the segmental pin E and an extension, J, below'the pintle G. -A rod or thick wire, K, is bent to form a link-guide and to fit around the end of the draw-head loosely. It is provided with two elongated side loops, L L, one fitting on each end of the pintle G, and two end crank-handles, M. The upper or outer extension, H, of the arm F is attached to a rod, cord, chain, or other device, by means of which the arm F and segmental pin E can be raised.

The operation is as follows: If the curved pin E is in the position shown in the righthand side of Fig. 1, the arm F is swung in the direction of the arrow, causing the curved pin E to pass through the link B, previously passed into the end of the draw-head, whereby this link will beheld as shown in dotted lines in the left-hand side of Fig. 1. If the link is held in one draw-head it only need be guided into the opposite draw-head, and as soon as itstrikes thelower extension, J, of the arm Fitthrowsthe arm F and the curved pin Eforward in the direction of the arrow,causing the pin E to pass through the link. To guide the link I have provided the linkguide K, which generally hangs down, as shown in Fig. 1, on the righthand side. If the link is to be raised, the linkguide 'is turned on the piutle G by means of one of the crank-handles M. The elongated loops L permit of moving the link-guide forward or backward, as may be necessary.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a car-coupling, the combination of the coupling-link B and the draw-head A, provided with the central end recess, B, the slot 0, and the segmental aperture D, extending entirely through the draw-head, the arm F, pivoted in the said draw-head and provided with. the segmenfal coupling pin E, the projection H above the coupling-pin, and the projection J below its pivot-pin, substantiallyas shown and described, whereby the coupling-pin is adapted to be tripped by the end of the link striking the projection J of the said arm, as set forth.

2. In a car-coupling, the combination, with 'the draw-head A and the pintle G, haying its ends extended on each side of the said drawhead, of the swinging guide-frame K, provided with elongated side loops, L, and crank-handles M, substantially as shown and described, whereby the guide is adapted to be moved forward or backward, as may be necessary, as set forth.
