UNITED STATES PATENT OFFICEo GEORGE W. PUTNAM, OF SOUTH GLENS FALLS, NEW YORK.

IMPROVEMENT IN OAR-COUPLINGS.

Specication forming part of Letters Patent No. 143,716, dated October 14, 1873 application led J une 26, 1873.

To all whom t may concern:

Beit known that I, GEORGE W. PUTNAM, of South Glens Falls, in the county of Saratoga and in the State of New York, have inventedl hereinafter described.

In the annexed drawings, Figure 1 represents a plan view of link. Fig. 2 represents a side view.

v In the drawings, A represents a metallic bar with a link, A', formed at one end ofit. Be'- tween the sides of the link is placed a curved metallic plate, as represented in Fig. 2, the ends of the plate projecting beyond the sides of the link, as seen. A coiled-wire spring, which surrounds a rod, a, presses lthe plate outward. This spring yields in the concussion of coupling, and assists in breaking the jar.` One end ofthe bar A has a half-round hook, as seen at which acts as a draft-hook at that end. Hinged to the bar A is a spring-keeper, B. This keeper has its outer end pressedA against the point of hook on bar A, and keeps the pin from release after once being caught.

The bars A and B separate in V shape at their ends, as seen from d to c c, so that the pin may readily be received between them when in the act of coupling.

The operation of this link is very simple, as that portion of the bar on which the loop is formed is rst connected to a car by the ordi- 1 nary pin, the V-shaped end projecting out toward the car to be coupled. The pin of the car to be coupled is dropped in place, and as the cars come together the pin strikes in the V-shaped opening between the pins, and is thus carried, as directed, between them, and, of necessity, caught by the hook at rv.

O is a center bumper.

This link is simple and inexpensive, and will obviate the necessity of changing the drawheads, andhaving self -coupling machinery' attached to the cars. A

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

The barA, having a loop and spring' plate at one end and a hook, a2, and bar B at the other, all combined and arranged as and for the purpose herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of June, 1873.

GEO. W. PUTNAM.
