CAR-.COUPLING.

SPECIFICATION forming part of Letters Patent No. 464,572, dated December 8, 1891.

Application led July l5, 1891.v

To all whom t may concern.-

Beitknown that I, GEORGE D. LEWIS, a citizen of the United States, residing at Port Allegheny, in the county of McKean and State of Pennsylvania, have invented a new and useful Oar-Coupling, of which the following is a specification.

This invention relates to car-couplings of that class known as twin-jaw, and the object thereof is to produce certain improvements in devices of this character.

To this end the invention consists in the construction hereinafter more fully described and claimed, and as illustrated on the sheet of drawings, wherein- Figure 1 is a perspective view of the end of av car with my improved coupling attached taken slightly from the under side. Fig. 2 is a plan View of two draw-heads coupled or connected, the upper sides thereof being removed to more clearly illustrate the interior construction. Fig. 3 is an enlarged perspective detail of one wing and its operating-lever.v

Referring to the said drawings, the letter B designates the body of thecar, beneath which is secured the draw-bar D, whose front end or draw-head is U-shaped in plan and connected at its bend with the draw bar. The latter stands slightly out of the transverse center of the car, so as to throw one of the arms A of the draw-head nearly in the center, while the other arm A is quite remote therefrom. In the front end of the arm A is the usual opening O for the reception of an ordinary coupling-link when this. draw-head is to be connected with one using such link. The arm A is hinged, as at H, to the body of the draw-head, so that it can be turned outwardly, as seen in dotted lines in Fig. 2, and a hook h, pivoted to the top of the body, en-

' gages a staple or eye t' in the top of the arm which is hollow and then turn to the rear,

whereby the wings are prevented from movving outwardly too far.

` L is a lever centrally pivoted within the body and pivotally connected at its front end with one of the feet F, and S is a spring operating on this lever in a direction to move the Wing normally out of the recess R. In the arrn A there are two such levers mounted on a single pivot like a pair of shears, and of course moving oppositely in order to draw the wings simultaneously inward.

C arev chains leading from the levers inwardly, and one of these chains O', which leads from the lever that operates the wing on the outer face of the arm A passes around a pulley P, as shown. The meeting ends of theA chains are connected, pass upwardly through a hole in the top of the draw-head, and lead to any suitable devices (not shown) for uncoupling. W'ith this construction of devices it will be obvious that when the two draw-heads come together, as seen in Fig. 2, the wings will spring outwardly and engage each other; and that when it is desired to uncouple the cars a pull upon the chain C will move all the levers L simultaneously, compress their springs S, and draw the several wings WV into the recesses R, whereby the other draw-head would be allowed to pullout. The parts are of any desired size and material and considerable departure in the specific details may be made without losing sight of my invention. The height or vertical thickness of the draw-head maybe considerable,

and hence cars whose draw-heads stand at- IOO arms of said draw-head, L-shaped feet on said Wings passing into the draw-head, pivoted and spring-actuated levers bearing said feet and Wings normally outward, and chainsleading from the rear ends of said levers over suitably-located pulleys to a common point, and thence out the top of the draw-head, as and for the purpose set forth.

2. In a car-coupling, the combination, with the draw-bar, the U-shaped draw-head secured at its bend to the front end thereof, one

of the arms being rigid with and the other connected by a hinge to said body, and a catch for holding this arm normally rigid, of spring-actuated Wings on both faces of the 15 Vrigid arm, a single Wing on the inner face of
