CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 497,684, dated May 16, 1893.

Application tiled March 2, 1893. Serial No. 464,471. (No model.) Y

To @ZZ whom t may concern.-

Beit known that I, EDGAR T. PEIRCE, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and Improved Car-Coupling, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved car-coupling, which is simple and durable in construction, very effective in operation and arranged for automatic coupling and easy and convenient uncoupling from either side or the top ot' the car.

The invention consists of certain parts and details and combinations of the saine, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the Iigures.

Figure l, is asectional side elevation of the improvement'showin'g two cars coupled. Fig. 2, is a like View of the same, showing the cars uncoupled. Fig. 3, is a front View, with the improved automatic coupling hook raised, exposing to View the enlarged part or box of the coupling hook with its throat or opening. Fig. 4, is a side View ot' the plan ot' the improved coupling hook, with a part oi' the drawhead. Fig. 5, is a front view of the improved coupling hook with a common link inserted in the throat.

In Fig. l the automatic coupling hooks B. B. are engaged to the drawheads A. A. by the pivot pins C. C. and the cars are coupled together by the coupling hooks D. D. dropping over the pivot pins C. C.

In Fig. 2. by means of the chain t, the automatic coupling hooks B. B. have been raised matic coupling hook B. is thrown up to almost a perpendicular position by means of the upright rod R, or the levers L,L, which are connected to the automatic cupling hook B by.

the chains 1f. t. t. attached to the loop or ring O at or near the middle of the coupling hook B.

In Fig. 4, is shown a lateral section of the automatic hook giving a side view and its engagement to the drawhead A and showing the box enlargement E, with its throat T., and pin hole P.: and lug H which rests against the lower front end of the drawhead A, to hold the coupling hook in a horizontal position when desired to couple automatically. The front end of the box E is so arranged as to strike against the beveled or curved edge M of the lower side of a similar coupling hook of another car, that may be coupled to it and thus raise "it simultaneously with itself whenever raised.

In Fig. 5 is shown the engagement ot' a coulmon coupling link Z by the pin P in the throat T, when connecting a common car not having this improved automatic coupling hook.

I claim as my invention and as new and desire to secure by Letters Patentl. In a car coupling, the combination of a drawhead with an automatic coupling hook having an enlargement or box on one side, and in front ot its pivot pin,suiiiciently large to contain an opening or throat for the use of ordinary coupling links to be secured by their ordinary coupling pins, when desired, substantially as described and set forth.

2. A car coupling consisting of a couplinghook having a curved or beveled edge, and provided on its side with the box or coupling throat E, so arranged that it may strike against the curved orbeveled edge of the opposite coupling, and raise it automatically, and on which it may afterward engage, substantially as described and set forth.

EDGAR T. PEIRCE.
