SPECIFICATION forming part of Letters Patent No. 746,025, dated December 8, 1903.

Application filed December 16,1902. Serial No. 135,456. (No model.)

To all who-1n it ritrty concern.-

Be it known that i, THOMAS CHEW, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented new and useful lin provernents in Oar-Couplings, of which the following is a specification.

My invention relates to improvements in car-couplings, and more particularly pertains to that class which is automatically coupled and locked in said position.

The object of myinvention is to provide a coupling of this character in which the link is more eii ectivelylocked in its operative position and the unlocking of said means raises the link and releases it.

Another object of my invention is to provide a coupling in which the ordinary link and coupling-pin can be readily and effects iveiy used without injury to any of the Workparts of my invention.

A further object of myinvention is to provide a simple, cheap, and more effective coupling of this character than has heretofore been produced.

in the accompanying drawings, Figure l is a perspective view of my coupling, showing the uncoupling means and the links connecting the locking means. Fig. 2 is a vertical sectional view taken on line 2 2, Fig. 1. Fig. 3 is a transverse sectional view taken on line 3 3, Fig. 1. Fig. at is a perspective view of the coupling-links.

Referring now to the drawings, A and B represent the two members of the coupling, which may he of any form or shape on the outside, but preferably that shown in the drawings, and are provided with the elongated V cesses C, which have their outer ends flared at 0, like the ordinary coupling, for the purpose of guiding the link to said recesses. The upper face of said recess 0 is provided with a curved recess D,which is provided with a vertical straight wall (Z. Passing transversely through the said recess is a bolt or rod E, which has rigid ly connected and carried thereby the locking member F. The said locking member hasits upper and lower-ends beveled, and thus it will be seen that said member is adapted to swing rearwardly within the recess, but is prevented from swinging forward by the straight wall d. The said rod or bolt E is journaled within the body portion of the cou pling, and one end extends out beyond the outer surface thereof and carries a squared portion e, the purpose of which will behereinafter more fully described. The lower portion of. the said body portion of the coupling is provided with a curved recess G, which is considerably deeper than the recess D and is provided with a curved rear wall 9 and a forward rearwardly-extending oblique wall 9'. Extending transverse the lower curved portion of the lower opening is a bolt or rod H, which has its ends journaled in the sides of the body portion of the coupling and has one end extending out through the same side as the rod E and has its extreme outer end 7t squared, as shown. Rigidly connected to said shaft within the curved portion of the recess G is a member I, which has a curved portion 1' to fit within the recess and astraight portion 2' to allow the hooked portion of the link to drop within the upper portion of the recess. Surrounding the outer squared ends of the rods E and H are the links J and K, which have their outer ends and k pivoted to a vertical bar L and so arranged that when the member F, carried by the rod E, is in a horizontal position the member I, carried by the rod H, is in a vertical position, and vice versa. The said coupling members A and B are provided with vertical openings M, comniunicating with the rear portion of the openings C and adapted to receive the ordinary coupling-pin, and thus it is seen that my device can be readily used in connection with the ordinary link and coupling-pin S.

The upperend of the link L carries an eye Z, and secured within said eye is a link N, which has its upper end extending upwardly and secured to a crank-arm 0, which is carried by a rock-shaft P, which is carried by the side of thecar and adapted to oscillate. The opposite end of the rock-shaft P carries an operating handle or crank Q, and upon turning said crank it will be readily seen that the link is readily raised and the car uncoupled, and upon releasing said crank the weight of the link L will throw the members F and H in the position shown on the right of Fig. 2, and thus the link is adapted to automatically couple and lock itself in said position. In order to positively lock the link in its coupled vide a transverse opening R, which is adapted to receive a pin S, and thus it will be seen that the member F cannot possibly be swung upwardly, and thus the coupling-link T cannot be raised out of the recess G. The said link T is composed of a fiat piece of metal having at one or both ends the downwardlyextending hooked portion 25, provided with a beveled portion 15, which is adapted to drop into the recess G and engage the oblique forward wall g thereof. When the said link carries a hook at but one end, the opposite end carries a vertical opening 25 which is adapted to receive the ordinary coupling-pin which is at all times carried by both members of the coupling.

The operation is as follows: The weight of the link L normally holds the two members in the position shown on the right of Fig. 2, and as the link T enters it forces the member F rearwardly until the hook portion 15 comes opposite the opening G, and then the weight of the link L through the member F forces the link T into said recess G and the said member F looks it against any upward movement. When it is desired to uncouple the cars, the link L is raised, as heretofore described, thus throwing the member F rear wardly, so that the link T can be raised and the member I is thrown forward and engages the beveled portion of the hook tand raises it out of the recess G, thus uncoupling the cars.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is
