IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 198,680, dated December 25, 1877 application filed November 17, 1877.

To all whom it may concern:

Be it known that I, GEORGE W. PUTNAM, of Glens Falls, in the county of Warren and in the State of New York, have invented certain new and useful Improvements in Gar-Couplings; and do hereby declare that the following is a full, clear, and exact description thereof, reference, being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.

The nature of my invention consists in the construction and arrangement of a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled, in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure l is a longitudinal vertical section.

of my car-coupling, and Fig. 2 is a plan view of the same.

A represents the draw-head, with the usual flaring mouth B and interior chamber 0. Dis the coupling-pin, provided near its upper end withprojecting journals ortrunnions aa, which are insertedin enlarged holes b b formed in the jaws of a forked arm, E. This arm is pivoted in a sort of three-sided box, H, formed on or attached to the top of the draw-head.

The arm E prevents the pin from becoming lost at any time, and also aids the pin in going down through the head in coupling the ears. I

d is the hole in the top of the draw-head for the passage of the pin '1), andv d is the correspondin g hole in the bottom of the drawhead. This latter hole d is made elongated sufficiently for the end of the coupling-pin to pass into the same as it comes down on a curve by reason of the arm E. This curve is, however, reduced to the minimum by the trunnions a being placed in the elongated holes b in the fork of the arm E.

In front of the hole 01 in the top of the draw-head is a step, as, for the pin to rest in afteruncoupling. When it is desired to couple the cars the pin is placed in a step, y, in rear shown, it is made to surround a guide-pin, z,

projecting rearward from the block. In addt tion to this a headed pin, m, projects from the under side of the block through a Iongi tudinal slot, n, in the bottom of the drawhead.

The fi'ont of the sliding block G is made beveled from the top downward and rearward,

so as to overhang the inner end of the coup ling-link I, and thus hold the same in a horizontal position for easy entry into the opposite draw-head.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The box H, pivoted forked arm E, with slots b in its jaws, and the pin D, with trun nions a a, in combination with the draw-head 1 A, having pin-hole d, with steps as 51 formed in front and rear at the top of said pin-hole, substantially as and for the purposes herein set forth.

In testimony that I claim-the foregoing I have hereunto set my hand'this 22d day of October, 1877.

GEORGE w. PUTNAM.
