IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 108,404, dated October 18, 1870.

To all 'whom it lmay concern:

Beit known that I, WARREN B. SNEDAKER, of Phoenix, in the county of Oswego and State ot' New York, have invented a new and Improved Car-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l represents a side view, partly in section, of my improved car-coupling. Fig. 2 is a plan or top view, partly in section, of the same. Fig. 3 is an end view of the same. Fig. 4is a plan view of the link. Fig. 5 is a longitudinal section of the link.

Similar letters of reference indicate corresponding parts.

This invention is an improvement in the class of car-couplings whichisknown as selfcoupling;77 and the improvement consists in the peculiar construction and arrangement of the devices constituting the coupling, whereby they are adapted to operate as hereinafter set forth.

A A in the drawing represent the drawheads of two cars. B is the coupling-link. This link has an additional amount of metal, a, at one end, so that it is heavier and will be held horizontal by the additional Weight.

In ears b b, that project from each drawhead, is hung a transverse shaft, E, which has projecting cranks c o, to the ends of which the pin D is pivoted. The pin D ts through a slot of the draw-head, and is supported on the cranks c by means of a projecting flange, d. It is also provided with a projecting knob, e, to facilitate handling.

The shaft E has, furthermore, two project ing arms, f f, which are weighted at the ends to hold the pins down. When, by raising the knob e, or swinging the shaft E, the pin D is raised, it is drawnlforward, and will thus clear the link without requiring the cars to be pushed together. When the car is uncoupled the pin will hang the same as when coupled, but will yield to the inserted link to permit automatic coupling, the weighted arms drawing it down again immediately after it is clear at the lower end.

The ears b have stops g, which arrest the cranks c, preventing the raising of the pin beyond the necessary height.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- The coupling-pin D, provided with the lange d, the shaft E, crank-arms c, and weighted arms ff, combined with the slotted draw-head A, provided with stops g, all constructed and arranged in the manner shown and described.

WARREN B. SN EDAKER.
