BERNARD BIRD, OF BUFFALO, NEW YORK.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 352,511, dated November 16, 1886.

Application filed February 10, 1886. Serial No. 191,389. (No model.)

To all whom it may concern:

Be it known that I, BERNARD BIRD, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Car Couplings; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to improvements in car-couplings; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claim.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure l is a side elevation of a pair of draw-heads coupled together, the one at the right hand being shown affixed to a fragment of a car and supplied with an uncoupling device. Fig. 2 is a longitudinal sectional elevation, and Fig. 3 a plan of a draw-head Figs. 4 and 5 are end elevations of the draw-heads.

Like parts are designated by corresponding letters of reference in all the figures.

This invention embodies improvements upon the device for which Letters Patent of the United States were granted to me September 23, 1884, No. 305,418, the object being to provide for means for carrying a link and pin with each draw-head, so as to prevent the possibility of two draw-heads meeting without a coupling link or pin to make connection, and

also in a novel device for upholding the link within the draw-head during the time that connection is being made.

The principal features of my car-coupling are the same as those of the device described and claimed in the Letters Patent heretofore recited, viz:

A is the draw-head, having on one side and nearits forward end two lugs, A,within which is pivoted, by the bolt a, Fig. l, a link, F, to which is secured a second link, G, the latter being an intermediary between said link F and the coupling-link proper, B, as clearly shown in the drawings, whereby the last-mentioned link is permanently secured to the draw-head, and always ready to be used in coupling whenever occasion requires.

O is the coupling-pin. It is vertically movable within the pin-aperture 0, Fig. 2, of the draw-head, but prevented from being removed therefrom by a pin, 0, striking against a shoulder, b, in said aperture, there being two grooves, g g, in the aperture 0 for the passage of said pin 0. pin-aperture O is an offset, 6, Fig. 5, upon which the pin G,when pulled up as far as possible, may rest, to prevent coupling, which is very desirable in many cases. I

Behind the coupling-pin there is in th draw-head a rise, D, terminating in a cylindrical projection, D, there being located within said projection D a bolt, E, having its head acted upon by a spiral spring, E, for the purpose hereinal'ter'to be referred to. In the sides of the projection D are oppositely-located slots d, through which passes a bolt, d, carrying the dog H, which dog sustains the pin 0 prior to coupling, and upholdsthe link, substantially as described in the patent already mentioned, except that the head of the bolt E, pressing upon the dog H by the spiral spring E, sustains said link B in a substantially-horizontal position, the action being assisted by a tailpiece or counterpoise, I, Fig. 2, operating in the passage J, running longitudinally through the said draw-head, said counterpoise being pivoted to the dog at h. v

To the face of the car-body O is secured a hand-rod,N,having centrallyabell-crank,Mm, said rod being j ournaled in properly-arranged bearings, readily understood. Above this hand-rod, in the middle of the car above the draw-head, is pivoted a lever, L, to which the coupling-pin O is attach ed by means of a chain, K. Depressing the hand-rod N causes the bell-crank M to lift the lever L, and this in turn to pull the pin upward, thus uncoupling a pair of draw-heads in the easiest possible manner.

The operation of the cars in coupling does not differ materially from that described in my Patent No. 305,418, and a description thereof is therefore deemed superfluous.

In the upper part of the ICQ Having thus fully described my invention, In testimony that I claim the foregoing as 10 I claim as new and desire to secure to me by my invention I have hereto set my hand in Letters Patent of the United States the presence of two subscribing witnesses;

The combination, with the draw-head and 5 coupling-link, of the pivoted dog H, bolt E, BERNARD BIRD.

with spiral spring E, and the eonnterpoise I, pivoted to said dog and arranged to operate Witnesses: Within the passage J as and for the purpose MICHAEL J. STARK, set forth. JESSIE A. TULLEY;
