CAR-COUPLING.

SPECIFICATION formiiig part of Letters Patent No; 270,057, dated January 2, 1 883,

- Application filed June 24, 1882. (No model.) i

To all whom it may concern:

Be it known that we, DUDLEY W. HAJNES and ALWYN D. HANKERSON, of Readfield,

Kennebec county, Maine, have invented a new and Improved Uar-Goupling, of which thefollowing is a full, clear, and exact description. This invention relates to improvements in car-couplings, having for its object to cfl'ect the ready and easy coupling and uncoupling of the cars; and it consists in the combination vided with our improved car-coupling. Fig.

each side of the car.

the top, for holding this chain taut.

2 is a longitudinal elevation of the car-coupling. Fig. 3 is a cross-sectional elevation of the same onthe line mm, Fig. 2; and Fig. 4 is a cross-sectional elevation of the same on the line y y, Fig. 2.

The draw-head A, which has the outer end of its opening beveled in the usual manner, is provided with a block, B, on its top, through which block and the draw-head the couplingpin 0 passes vertically; and to the upper end ofthis pin an angular rod or bar,D, is attached, which passes down on the front surface of the block B, and has the lower end pivoted to the end of one arm of a bell-crank or elbow-lever, E, pivoted to the block B. To the other end of this lever E a chain or equivalent device, F, is attached, which has its opposite end fastened to the outer edge of the end of A hook or catch, G, is provided on the end of the car, near the side edge, on which hook or catch the chain F can be fastened to hold it taut. If desired, the rod or bar D can be pivoted to levers E, one to be operated from A chain, H, has its lower end attached to the upper end of the couplingpin' C and the--upper end of this chain H is fastened to the top of the car. A hook or catch, I, is provided on the end of the car, near A spiral spring, J, surrounding the coupling -pin 0, presses'the same downward, but may be dispensed with, if desired. A slide, K, in the side of the draw-head is pressed inward bya spring,

L, surrounding the stem of this slide. The end of this slide is beveledand provided with a semicircular recess, so that it will fit closely against the link M. A metal block, N, :is pressed down into the throat of the draw-hea by a spring, 0, above it. p

The operation is as follows: The pin 0 is raised from the sides or the top of the car by pulling on the chain F or H, and when the lower end of the pin is above the upper edge of the slide K this slide is pressed under the pin by the spring L, so that the lower end of the pin will rest on this slide. together the entering link M strikes the inner beveled end of the slide K and pushes this slide outward, thus permitting the pin to drop.

through the link, or to be forced through by the spring J, whereby the cars will be coupled. If the cars are not to be coupled, the pin is held -in the raised positionby drawing the chain For H taut and hooking it on a hook or catch, G or I. The block Nis pressed upon the inner end of the link and holds the same in a horizontal position, thus greatly facilitating coupling. The stem or spindle of our improved drawhead is like that of the draw-head of the usual construction, which can be replaced by our improved draw-head in a very short time.

Having-thus described our invention, we

claim as new and desire to secure by Letters Patent t 1. In a oar-coupling, the combination, with the draw-head Aand pin (3, of the inverted-L- shaped bar or link D, having its horizontal arm connected to the upperend of the pin, the bell-crank lever E, connected to the lower end of the vertical arm of the bar D'and piv-. oted at its angle to the draw-head, and the operatingohain F, as shown and described, and for the purpose set forth.

2. The combination, withthe draw-head A, of the block N, pressed into the throat of the draw-head by the spring 0, substantially as herein shown and described, and for'the purpose-set forth.
