CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent N0. 294,810, dated March 11, 1884.

Application filed September 6, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, EDWARD J. RoBERTs, of Ashland, Boyd county, Kentucky, have invented a new and useful Improvement in Car- 5 Couplings, of which the following is a specification.

My invention relates to an improvement in those car-couplings which are adapted to couple automatically and to be releasable by a person standing to one side of or on top of the car. It is so devised as to employ the customary link, and so as to be capable of coupling with another car of the ordinary construction. I5 In the accompanying drawings, Figure 1 is an under side view, and Fig. 2 is a longitudinal section, of a car-coupling embodying my improvements. Fig. 3 represents, by a longitudinal section, the operation ofuncoupling. Fig. 4 is a front elevation of the coupling-jaws, the coupled link being'shown in section. Fig. 5 is a transverse section on the line 00 w.

A. may represent a portion of the bed-timbers of a railway-car. Bis the draw-bar, having its rear end supported in abutment-plate O, and the sliding cross-head D, and having its front portion supported upon bearing-bar E. The draw-bar B terminates at its front portion in the hook-formed jaw F, beveled rearward and downward, as at f. A pin, G, and collar H, near the rear end of the drawbar, serve to limit its forward movement to the position shown in Figs. 1 and 2. Rearward'movement of the said draw-bar, and also rearward movement of the draw-head R, is resisted by a powerful helical spring, J, interposed between the abutment C and the sliding cross-head DJThe draw-head R consists of a stirrup-shaped piece of iron, whose convex 40 and perforated face-plate 1' is secured to a U- formed shank, a", perforated for the traverse of the draw-bar, ,andopen above and below, as shown. The draw-head is maintained at its normal position by the spring J J, and the draw-bar partly by that spring and partly by 5 a helical spring, J, interposed between the inner shank, r, and a collar, 1), upon the drawbar. Still another, but much lighter, helical spring, J, interposed between said collar and a sliding sleeve, K, holds to its normal or go latched condition (see Figs. 1, 2, and 4) av sliding jaw, L, having the represented upward and rearward bevel front I. Inward thrust of the inserted link M is received by a vertical shoulder, l, of the draw-bar. A 5 5 forked lever, N, pivoted to the jaw L, and connected by chain 0 to crank 12 on the crankshaft P, and having a handle, Q, accessible to the attendants, enables such attendants, by retracting the jaw, L, to the position shown in 60 Fig. 3, and at the same time advancing and lowering the forks of the lever, to eject the link, as shown in said figure, and thus uncouple the car. In addition to these uses, the crank 12 may be brought (see arrow in Fig. 2) 6 5 to press against the under side of the drawbar, and by so doing adjust the inclination of the link, to facilitate coupling with a car of different height to that which carries thelink.

I claim as new and of my invention- In a railway-car coupling, the combination of draw-bar B, having the integral jaw F and the sliding jaw L, the independentlysliding draw-head R, the springs J J J, and the re leasing-lever N, and operating crank-shaft P, 75 substantially as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.

EDWARD J. EoBEErs.
