IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 186,373, dated January 16,1877; application filed September 4, 1876.

To all whom it may concern:

Be it known that I, JOHN W. SKEELE, of Syracuse, Onondaga county, State of New York, have invented an Improved Draw-Head for Oar-Coupling, of which the following is a specification My invention relates to that class of carcouplings in which a block resting on an inclined bearing serves to retain the link in its horizontal position, support the pin prior to coupling, sustain the link against the resistance of the opposite block, and yield to permit the link to pass beneath when the pressure is excessive; and my improvement consists in constructing the different parts as fully described hereafter, to insure strength, facilitate the operation, and reduce the expense of manufacture.

In the drawing, Figure 1 is a longitudinal section of the coupling. Fig. 2 is a plan.

Fig. 3 an end view of one of the draw-heads, holding the link, and Fig. 4 a perspective view of the block.

The opposite draw-heads a a are externally of the usual shape, being of cast metal in the presentinstance, with the usual hell-niouthscc, and ordinary detachable pins 17 1). Each drawhead is solid, with the exception of an inclined opening, 01, extending from the top downward and forward to the mouth, and adapted to receive an oblong block or dog, 6, having at the forward end a notch'or recess, f.

When the pin 1) is raised-the block slides forward to a position beneath the lower end, and supports it as shown at the right in Fig. 1.

When a link is pushed inward, the block slides back and upward on its inclined bearing,

the two. If the free end of the link strikes the side of the draw-head, the link will he forced back, the block behind it forming a yielding backing thatetfectuallyprevents it from breaking.

As the draw'head is solid, except the opening d, it will possess great strength, while not exceeding in diinensions'those of the ordinary construction, and as the opening (1 is straight the draw-head may be cast without a core, and the inclined bearingfor the dog may be finished with greater facility than if it was curwed thus reducing the cost of construction over those made with chambers and side hearings, or with curved openings; in which the blocks can only slide when provided with friction-wheels.

I claim- The draw-head having the straight inclined openingd and vertically-sliding pin, in combination with the oblong block 6 adapted to said opening, as set forth.
