SAMUEL F. GREEN, OF SALAMANOA, NEW YORK.

CAR-COUPLING.

EPECIPICATION forming part of Letters Patent No. 318,107, dated May 19, 1885. Application tiled March 11, 1885. (No model.)

To all whom it may concern.-

Be known that I, SAMUEL F. GREEN, a cilizen of the United States, residing at Salamanca, in the county of Oattaraugus and State of New York, 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 appertains to make and use the same.

My invention relates to improvements in that class of car-couplers in which the coupling is automatic or self-acting; and the object of my invention is to produce a coupler which can be easily and safely uncoupled without eutering between the cars, and therefore without risk tolife orlimb, and which will be sim ple of construction, cheap to manufaeture,and durable. This obj eet I attain by the construction and combination of parts as hereinafter described and claimed.

In the accompanying drawings, Figure l isa perspective view of my device coupled; Fig. 2,a like view showing it uncoupled; Fig. 3, a plan view-of the receiving ordra-w head; Fig. at a like view of the arrow-headed coupling link or bolt, and Fig. 5 a detail view of the operating-lever.

Similarletters refcrto similar partsthrouglr out the several views.

A represents the receiving or draw head. This head is made of spring metal, preferably in two parts, and secured together at the end lettered (t by bolt or otherwise, so as to resist the strain when the jaws B are forced apart. The jaws B are curved or flare outwardly and away from each other at b, so as to leave sufficient space for the arrow-headed link or bolt 0 to readily find its way between them to force them apart.

The jaws B are notched on their contiguous faces immediately in the rear of their curved faces I), so as to form a heart-shaped recess, D, when brought together, as shown in Fig. 1. The link 0, as before stated, is shaped like an arrow at its head and enters between the jaws until its points slip past the points of the recess,when the jaws close and hold the link securely in place. As shown, the link 0 conforms to the curvature of the jaws B at the point b,so that it may allow of play in rounding curves without forcing the jaws apart. Immediately in the rear of the heart-shaped recess or opening D the jaws are cut away,so as to leave an oval opening,E,when brought together.

F is a lever having an oval-shaped projec tion, G, on one end which enters the opening E of the head from beneath and fills it closely when the parts are in'the position shown in Fig. 1. This projection G is so arranged on the lever that a line drawn through its longest diameter would strike an angle of about fortyfive degrees to a straight line drawn through the lever in the direction of its length. This arrangement permits the lever F to extend outwardly and backwardly from the head when the jaws are closed, so as to be easily gi aiped by the operator without going between the cars. Upon turning thelever to the right, Fig. 1, the projection G forces the jaws apart, which permits of the withdrawal of the link 0, and thus uncouples the cars. The lever F rests and slides on a notched bar, H, which projects from the car to which the draw-head A-is attached, and is held in any desired position by catching the notches.

Vhat I claim as new,aud desire to secure by Letters Patent, is-

A car-coupler comprising a spring-metal head, A, having the oval opening E, thejaws B, having the heartshaped opening I) and curved faces I), the lever F,having projection G, the notched bar H, and the arrow-headed link'or bolt 0, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
