IMPROVEMENT lhl AR- COUPLINGS.

Specification forming part of Letters Patent No. 150,535, dated May 5, 1874; application filed March 6, 1874.

To all whom it may concern:

Be it known that I, ALEXANDER GRooKER, of the city and county of La Grosse and State of Wisconsin, have invented a new and Improved Oar-Oouplin g; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l is a side elevation partly in section; Fig. 2, a cross-section through line w x of Fig. 1; Fig. 3, a plan view of link partly broken away; Fig. 4, a crosssection of Fig. 3.

The invention will first be fully described, and then pointed out in the claims.

A represents a draw-head provided with the slot a, in which slides the cross-bar B, having the projections b. This supports the pin U until a link, D, strikes said projection, and

causes the pin to drop into the link. The slot to inclines downwardly toward the rear of the draw-headto allow the cross-bar B to avoid contact with the link after the cars have started, and thus to prevent the usual wear that takes place on the end of link. A A are buffer-heads which flare outwardly, and are made spacious enough to receive an enlarged portion of the middle of link. The latter is made in two parts, E F, one having the vertically-oblong hole '6, and the other having the projection f spread at the end, so that the latter may be inserted in the former, and the spread part turned round into a horizontal plane. G is a wooden pin which is inserted into the two half-circular grooves c f, one in section E, and the other in section F, of link.

By this construction and mode of fastening the two sections cannot come apart so long asthe conjoined cars remain on the track; nor can they turn on each other, by reason of the pin G; but if one car runs 011' an embankment or bridge and turns over, the wooden pin is at once broken, one section turns on the other, and the two sections are separated.

I am aware that a pin-supporting slide, having arms that slide in a groove of draw-head, is old; and also that a coupling, formed of two parts held together by a pin, forms no part of my invention.

Having thus described my invention, what I claim is 1. The combination, with the coupling-pin and its slide-support B, of a draw-head, having the slot a downwardly inclined toward the rear, as and for the purpose described.

2. The combination, with two sections pivoted together, and having the half -circular holes 0 f, of the wooden pin G, to prevent the sections from turning at ordinary times, but to break and allow them to turn it one car turns over, as set forth.

ALEXANDER OROCKER.
