GEORGE W. PUTNAM, OF GLENS FALLS, NEW YORK.

IMPROVEMENT IN CARFCOUPLINGS.'

Specification forming part of Letters Patent No. 156,593, dated November 3, 1874; application filed October 1, 1874.

To all whom t may concern.-

Be it known that 1*,GEoRGE W. PUTNAM,

of Glens Falls, in the county of Warren and in the State of N ew York, have invented certain new and useful Improvements in Oar-Coupler,

use the saine, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view of my attachment; and Figs. 2 and 3 are perspective views ot' the same.

My invention is intended to be used with the ordinary pin-and-link car-coupling, for the purpose of A making the same self-coupling.

To this end I'use two metal frames, A and B, each formed or provided with a bail or link, C, to be inserted in the ordinary draw-head,

common couplingrod, a, the front end of which is provided with a spear-shaped head, b, having beveled or turned sides, yas shown in Figs. l and 3. From the side of the shaft a projects a curved arm, d, which extends through a vertical slot in the frame A, and by its downward tendency holds the head b in a horizontal position. The frame B is elongated vertically, as shown in Fig. 2, and provided with a vertical slot, e, of the same width as the thickness of the shaft or'rod a.

My attachment being fastened, as described, in the draw-heads of two adjoining railroadcars, when the cars are brought together, the point of the head b enters the slot e, and revolves by the action of the beveled sides of the head, so that said head will pass through the slot e, and as soon as it clears the same the weight of the arm d returns it to its position, and thus couples the cars. The elongated frame B allows ofthe coupling of cars of very different heights. By raising the arm d, either by hand or by a cord or chain attached thereto, the cars are easily uncoupled.

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

The combination of the frame A, having link O and shaft a, with head b, and arm d, and the elongated frame B, having link O and slot c, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of September, 1874.

GEO. W. PUTNAM.
