ALBERT S. WAY AND JOHN WV. LUTZ, OF SPRINGFIELD, OHIO.

CAR-COUPLINGS SPECIFICATION formingpart of Letters Patent No. 270,865, dated January 16, 1883. Application filed November 22, 1882. (No model.)

To all whom it may concern Be it known that we, ALBERT S. WAY and JOHN W. LUTZ, citizens of the United States, residing at Springfield, in the county of Clarke and State of Ohio, have invented a new and useful Oar-Coupling, of which the following is a specification.

()ur invention relates to improvements in automaticcar-couplings,in which the oval coupling link and pin operate in conjunction ;.and the objects of our improvements are, first, to provide an automatic car-coupling; second, to afford facilities for properly performing the operation ofuncoupling withoutstanding between the cars; and, third,to provide means by which the breakage of coupling-links is avoided when coupling cars. We attain these objects by the mechanism illustrated in the accompanying drawings.

Fignre'l is a longitudinal sectional elevation view; Fig. 2, a longitudinal sectional plan View; and Fig. 3, an end view of part of a car, showing lifting device.

Similar letters refer to similar parts throughout the several views.

The draw head a (shown in Fig. 1) constitutes the frame-work ofthe coupling, said coupling a having a flaring mouth or receptacle, into which the couplinglink I) is forced, raising the adjustable draw-bare, which draw-bar c is pivoted on a hinge and pin in the vertical plane orside of the draw-head a, Fig. 1 the said draw-barchaving a jaw with front retreating nose and back perpendicular convex lip perfectlyadapted to the concaveinteriorprojection of the coupling-link b. The atbresaidjawofthe draw-bar c, after receiving the coupling-link b, is again forced back (and secures said couplinglink b) by the pressure of the bowed leaf-spring h, attached to the draw-head a, the said drawbar'c being lifted in uncoupling by the chain a, communicating with the lever device, Fig. 3, by the weightarm q, attached to the shaft k, attached toacar bythe hangers ll, (forming the fulcrum of the lever,) the whole being operated by the power-arms mm. i

The coupling-link bis held securely in a horizontal position by the combined pressure of the draw-bare and the oscillating butfing-block or spring-block 11, said buffing-block d having a concave mouth, being perfectly adapted to which mortise 1) passes the check pin j, said check pin j being permanently affixed in the draw-head a, as shown in Fig. 1, thereby keeping the .butfingblock (1 within reasonable bounds.

The coil-spring 0, Figs. 1 and 2, is also pro-.

vided with a stop-block, 9 or washer, to render firm and uniform pressure of the spring 6, said spring 6 being of sufficient strength to hold the coupling-link b firmly in a horizontal position when coupling, but of sufficient elasticity to permit the projection of the couplinglink b to retreat within the draw-head a when it is desired to push the car, thereby relieving the coupling-link bet the pressure, which pressure is sustained by the draw head a, all as shown in Figs. 1, 2, and 3.

Our invention is operated as follows: When coupling, the link I) is placed in the flaring mouth of the draw-head a, Fig. 1, said coupling-link I) being at all times kept in a perfectly longitudinal position, in the centerofsaid mouth of said draw-head, as by the action of the butting-block d and the pressure of the draw-bar c, the opposite projection of the coupling-link I), (being oval,) coming in contact with the flaring mouth of the draw-head a, is forced under the jaw of the draw-bar c, said draw-bar c having a flaring nose retreating inwardly from the mouth of the draw-head a, the jaw of the drawbarc having a back perpendicular convex droplip, which drops through the aperture of the coupling-link b and secures said coupling-link b, the buffingblock d closing up and holding the coupling-link b when coupling, but allowing the draw-heads to meet when pushing the cars. In uncoupling, the jaw of the draw-bar c is lifted by raising the power-arms m m, Fig. 3, the power-arms m m operating the shaft 7:,

(attached to the car by the hangers l l,) the In an automatic car-coupling, the combinashaft Ir haviu g attached to it a weight-arm, q, tion of an oscillating buffing block, d, with which draws the chain a, lifting the'draw-bar concave mouth and mortise p, with check-pin 1 0, said draw-bar 0 again forced back and set j, communicating with slidebarf and coil- 5 readyforcouplingby the spring h', as described, spring a, with stop-block g, all substantially as and shown in Fig. 1. described.

We are aware that prior to our invention 7 automatic car-couplings have been made. We 3 igi therefore do -not claim such various devices,

IO broadly; but Witnesses:

What we do claim, and desire to secureby TM. M. ROOKEL,
