JOHN M. BURDEN, OF H UN TSVILLE, KENTUCKY.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 407,164, dated July 16, 1889.

Application filed April 19, 1889.

T0 aZZ whom, it may concern:

Be it known that I, JOHN M. BURDEN, of Huntsville, in the county of Butler and State of Kentucky, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.

My invention is an improvement in earcouplings; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of one end of a car provided with my improvements. Fig. 2 is a side elevation, part in section, of two cars coupled according to i my improvements. Fig. 5 is a perspective view of the lower section of the draw-head. Fig. at is a perspeetiye view of the upper section of the draw-head, and Fig. 5 is a detail View of a different form of coupling-bar from that shown in Fig. 2.

The draw-head A may be connected with or secured'to the cars in any suitable manner, and is formed with the lower or main section B and the upper or hinged section 0, the latter section 0 being hinged at its rear end to the section B, so it may be raised at its front end, said end being normally depressed by the actuating-spring D bearing against it, as shown. In their inner or meeting faces that is to say, the under face of section 0 and the upper face of section B-I form, respectively, the recesses C B and the grooves C B leading forward from said recesses to the front of the draw head, where the draw-head is flared to properly direct the arrow-head c of the coupling-bar E to the grooves C 3 Such grooves C 3 form a guideway for the arrow-head e in the passage thereof into and out of the mortise formed by the recesses C B. The front wall of the recess 3 is rounded up into the groove B so as to direct the arrow-head up into such groove when the jaw or section 0 is lifted, while the front wall of recess 0' is made square, so as to positively hold the arrow-head when the section 0 is forced downward by the action of its spring. On the section B, I provide pins or dowels l), which enter sockets l) in the section C and guide the movement of the said section.

Serial No. 307,662. (No model.)

to uncouple the cars, I provide the horizontal shaft F and the vertical shaft- G, the shaft F being journaled to and extended across the end of the car and connected by cord or chain II with the section 0, so the proper turning of the said shaft F will operate to lift the section 0 and release the head of the coupling bar E. At one end the shaft F has a suitable handwheel f, and is provided at its opposite end with a bevel-gear f, meshing a gear 9 on the shaft G, such shaft G being provided at its upper end with a hand-wheel g, as shown. Now, it will be seen that the shafts F and G enable the brakeman, whether on the car or on the ground alongside the same, to uncouple the cars without going between them.

The cars may be coupled by simply securing the coupling-bar in one draw-head and forcing the cars together, when the free end of the bar will enter the other draw-head and be secured.

A low car may be coupled with a high one by using the bent form of coupling-bar shown in Fig. 5.

It will be seen that in the coupled position of the parts B and G the grooves B and C serve to receive the shank or body portion of the coupling-bar, so that such coupling-bar will be properly held at one end to enter at its opposite end a meeting draw-head.

llaving thus described my invention, what I claim as new is 1. In a ear-coupling, a draw-head comprising a body ormain section B, having a flared forward end provided in its upper side with a recess B and having a groove B extending between the said recess B and the flared forward end, and the spring-actuated section C, hinged to section B, having a flared forward end provided in its under side with a recess 0, and having a groove C extending from recess 0 forward to the front flared portion, all substantially as and for the purposes set forth.

2. The combination of the body or main section, the section 0, the shaft F, having a bevelgear f, a connection between shaft F and section C, and the shaft G, having a bevel-gear meshing that of the shaft F, substantially as set forth.

3. The improved cancOupling, substantially In order to conveniently lift the section (I as described, consisting of the draw-head having' a section B, forined with recess B and bevel-gear f, and the shaft G, having a bevelgroove B section 0, hinged at its rear end gear meshing the gear f. to section B and formed with recess 0 and groove 0 the dowels b, provided on one of JOHN BURDEN 5 such sections and entering the other, the WVitnesses:

spring for actuating the section C, the shaft A. H. TUOK,

F, connected with section 0 and having a JOHN N. DUNN.
