or NEW YORK, N.\Y.

Letters Patent No. 99,632, dated February 8, 1870.

The Schedule referred to in these Letters'Patent and making part of the same To all whom 'it may concern Be it known that I, LEOPOLD F. BUSCHMANN, of the city, county, andvState of New York, havev invented a new and improved `Gar-Coupling; and I do exact description thereof', which will enable those being had to the accompanying drawing, forming partof thisspecilication, in which drawing- Figure l represents a longitudinalvertical section of this inventionI when thle cars are coupled.

p Figure 2 is a similar section ot the same when the cars are unco'upled.

Similar letters indicate corresponding parts. Y

This invention consists in the arrangement ofa. hook, which is hinged to the draw-head, and acted upon-by a slide fitted into the draw-head and catching over the tail'eud of the hook, in such a manner, that by the action of the link or shackle-bar ou the slide, the hook is raised and caused to retain the link, and when the slide is released, the hook drops down, and the link is treed.

With the slide is combined a locking-catch, which retains the same, together with the hook, in their locking-position, and which can be operated by a handle from the top of the draw-head, in such a manner that when the catch is Ain its locking-position, the hook is prevented from releasing the link automatically, and when the catch is in its unlocking-position, the hook isf'ree to drop and release the link.

In the drawingrilhe letter A designates a draw-head, which is coul structed and attached to the cars in theusual manner.

In the interior of this dran/head is secured Va hook, B, which osoillates on a pivot, a, passing transversely through the draw-head, in such a position that it' the link C is pushed into the draw -hea-d, and the hook B is raised, it will catch in and retain said link lroin the inner end ofthe hook B extends a" tail, b, through a mort-isc. in the slide. D, which is fitted into the draw-head, and ii'ee to slide back and forth in the direction in which the link moves in and out; and, if the link is pushed into the draw-head, it strikes the slide and pushes the same back, and, by tbe action of the slide on the tail of the hook, said hook is raised andcaused to catch in the link. l

To the top of the slide D is secured a locking-catch, E, which is operated by a handle, F, projecting through the top of1 the draw-head.

When the slide D is pushed back, the catch E drops down behind a stop, e, which is cast solid with .the

draw-head, and vthe slide is retained in'the position By the action of the slide, the hook B is retained in its locking-position, and the link C is prevented' from getting disengaged. By raising the catch E, so

Ythat it clears the stop e, the slide D is released, and

the hook B is free to drop downto t-he position shown in fig. 2.

The catch E, as-shown in the drawing, is a simple plate, provided with a mortise, which drops over a lug rising from the slide D; but it is obvious that theforni and constrnct-ionof this catch could be changed in va ,rions differentways.

llhe handle F projects up through an oblong mprtise, f, in the top of the draw-head, and its shank is provided with two shoulders, g, so that lby raising theY handle and then turning it, these shoulders can be made to catch over the edges of the mortise f, thereby retaining the catch E in the position shown in tig. 2.

It' two cars are to `be coupled, the link is secured in the draw-headof one car, while ,the hook B iu the other car is let downto the posit-ion showuin iig. 2. As the link enters this last-named draw-head, the slide D is pushed back, the hook B is raised, and the catch E drops behind the stop e, bringing all the parts to the position shown in 1.

It' the cars are to be uncoupled, the handle F is raised and turned, so as to suspend the catch E in the position shown in lig. 2, and the hook B drops down and releases the catch.

The hole in the hook B, through which the pivot aY passes, is oblong, so that as said hook is raised, the strain ot' the link will draw it up against the shoulders It h, in the interior of the draw-head, and thereby the pivot a is relieved from all strain.

The slide D, when being pushed back, strikes the rear wall oi' the draw-head, and thereby the tail end oi' the hook is relieved from all injurious effect-s which might be produced by the powerful action of the link against the slide.

Having thus described my invention,

That I' claim as new, and desire 'to secure by Letters Patent, is-

l. The combination of the hook B, slide D, and locking-catch E, with the draw-head A.

2. The handle F, provided with shoulders g g, in combinationy with the draw-head A, catch E, stop e, slide D,vandl hook B, substantially as set forth.

This specification signed by me, this 7th day of J nly, 1869.
