COUPLING FOR MINING-CARS.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed April 24, 1914, Serial No. 834,107. Renewed January 3, 1916. Serial No. 70,082.

To all whom it may concern:

Be it known that I, EDWARD S. EARLS, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented a new and useful Coupling for Mining-Cars, of which the following is a specification.

My invention relates to improvements in couplers for mining cars, which are used under circumstances different from those under which railroad and street cars operate, and require for their better operation a different coupler. Mining cars are rapidly drawn bypowerful motors over rudely constructed tracks, which often have very sharp curves and sudden changes in grade. The ordinary link and pin coupler and the various interlocking couplers, used on railroad cars, are unsatisfactory, because they do not permit sufficient lateral and vertical movement of the cars. 7

The objects of my improvements are to secure an efficient coupler easily operated by hand without the operator going between the cars, and to permit the sharp and suddenlateral and vertical movements of the cars without their becoming uncoupled or derailed. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a View in perspective of the entire device, and Fig. 2 is a similar view of the fiat connecting link or bar C.

Similar letters refer to similar parts throughout the various views.

The clevis A (Fig. 1) is to be attached by a pin to the drawbar D of a car. The flat connecting link or bar C, with a perforation in each end, is, by one of its perforated ends, to be connected with the clevis A. To the drawbar D of the opposite car, the 3 link E, by the closing of one of its ends, is to be attached securely, and the other end thereof, being recurved to avoid discon- Gopies of this patent may be obtained for five cents each, by addressing the nection, is to be connected with the flat connecting link or bar C. The connection is perfected by inserting the open and recurved end of the 8 link E into the perforation of the disconnected end of the flat connecting link or bar G. In this manner the coupling of the cars is completed. The cars may be readily uncoupled by slacking them and lifting the flat connecting link or bar G; whereupon the 8 link E will become disconnected. The flat link or bar C and the 8 link E each remain attached to its respective car, and are ready to be coupled again. There are no parts or pins to become detached or lost.

My invention permits the lateral motion of the cars, caused by turning sharp curves at high speed, and also the vertical motion thereof, caused by sudden changes in the grade of the tracks, without the cars becoming uncoupled or derailed.

I am aware that, prior to my invention, links and bars in various patterns have been used in car couplers. I, therefore, do not claim th combination broadly, but

l/Vhat I do claim as my invention, and desire to secure by Letters Patent, is

The combination, in a car coupler, of a clevis A, which is to be attached by a pin to the drawbar of a car, of the link E, in the form of a letter S, which is to be fastened to the drawbar of a car, by the closing of one of its ends and having its other end open and recurved, and of the fiat connecting link or bar C, having a perforation in each end, which is to connect with the clevis A, and also to receive, in the perforation of its disconnected end, the open, recurved end of the 8 link E, all substantially as set forth and for the purpose specified.

EDWARD S. EARLS.
