.To @ZZ whom t may concern;

Be it known that we, EDWARD HUBER and HENRY M. BARNHART, citizens of the United States, and residents of Marion, in the county of Marion and State of Ohio, have inventedV certain new and useful Improvements in Car- Couplings and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the` art to which it appertains to make and use the same, reference being had to the accompanying drawings, whichform a part of this specication, and in which- Figure lis a longitudinal vertical sectional view of our improved car-coupling, showing it ready for coupling.

showing it coupled. Fig. 8 is a similar view `showing the pin drawn up and resting with its point in its recess in the act of uncoupling; and Fig. 4t is a cross-section on line x x, Fig. 2.

Similar letters of reference indicate corre-` sponding parts in all the gures.

. Ourinvention has relation to that class .of automatic car-couplings inwhich the pin ,when uncoupled, is supported by a projecting lip upon a spring-block,'sliding in the recess in the draw-head and adapted to be pushed back by the coupling-link; and it consists in the improved construction and combination of parts of, such a coupling, in which the perforation fr the coupling-pin has 'a recess at its upper end for the reception of the point of the pin, and in which the spring-block has an upwardly-projecting lip sliding ina longitudinal slot in the draw-head, guiding lthe block and pushing the pin out of its recess when forced forwardby the spring, as hereinafter more fully described and claimed.

In the accompanying drawings, the letterA indicates the draw-head, which is of the usual construction, having the usual vertical perfoi ration, B, forthe reception of the pin C, while its recess D is extended rearward, forming a perforated bearing, E, in which the rearwardly-extending bar F of the sliding spring-block Gr slides,` and against which the rear end of aspring,II, wrapped around the bar, bears,

the forward end of which spring bears against rear side of the block, forcing it forward.

5o The upper forward edge of. the sliding block Fig. 2 is a similar view forms a forwardly projecting lip, I, upon which the point of the pin rests when drawn up, and the upper side of the block is provided with a longitudinal upwardly-projecting lip, J, which slides in a longitudinal slot, K, inthe upper side of the recess in the draw-` head. The rear side of .the upper portion of thevertical perforation for the pin forms a l recess, L, inclined slightly rearward with its lower end, and the longitudinal slot, which is narrower than the recess, enters the lower end of the same. When the cars are brought closer together for uncolipling, the link will force the spring-block rearward, and the pin may be raised and placed with its end in the recess, its upper end pointing forward 5'and in withdrawing the link the spring-block will slide forward, pushing the point of the pin forward out of the recess with the upwardlyprojecting lip, when the point of the pin will4 rest upon the forwardly-projecting lip; and

it will be seen that when the link again isA introduced into the draw-head the sliding spring-blockwill be forced rearward, allowing the pin to drop in the perforation and throughthe link, coupling again. It will also be seen that the upwardly-projecting lip will serve as a guide for the sliding spring-block,

besides serving to push the pointof the pin forward, and that by having the recess inthe perforation for the pin the pin may be withdrawn and beheld in its raised position while the link .is holding the spring-block back,

which cannot be done in couplings of this class having only a forwardly-projecting lip upon the spring-block, which can only hold the pin h raised when the' link is out of the draw-head, consequently necessitating the presence of the brakeman at the coupling exactly atmthe moment when the cars are to be uncoupled.

Having thus described our invention, we claim-knowingthateouplingshavebeenmade with sliding spring-blocks having forwardlyprojecting pin-supporting lips-as follows:

rlhe combination of a draw-head having the" usual vertical perforation for theY pin, pro vided at the rear side of Vits upper portion with a recess, and having a longitudinal vrecess forming a narrower slotv at its upper side,the forward end of the said slot entering the-lower IOO end of the recess in the pin-recevng perfoour own We have hereunto affixed ,our signamtion, 2t spring-actuated block having :L fortures in presence of two Witnesses.
