IIWIPROVED CAR-COUPLING.

The Schedule referred to in these Letters Patent and making pa'rl: of the same.

To all whom it may concern: 7

Be it known that I, W. G. BELL, of Pittsburg, in

is a full, clear, and exact description thereof, which will,

enable others skilled in the art to make anduse the same, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 is a cross-section of my invention, through the line it x, fig. 2. v

Figure 2 is a longitudinal section, through the line y fig. 1'

Figure 3 is a detail view of the coupling-box and rod.

Figure 4 is a transverse section of the coupling-rod.

Similar letters'of reference indicate corresponding parts.

A A A is the tapering aperture of the coupling-head B, which is madeoblong, the longest way being from top to bottom, (so as to adapt it to cars of difler'ent heights,) arranged immediately behind which are the lateral catch-plates, a a, which are pivotedor hung to the part B, atthe top, and bent and arranged to cross eachother at d, so that if the springs e e, which are intended topress-theni together so as to hold firmly the head of the coupling-rod 0, should at any time break, the tendency will be to fall together and still hold the rod.

K is a lever-button, pivoted between the lower ends of the catch-plates a a, and serves to separate them when the cars are to be uncoupled. By turning this button to the right or left, which may be done by means of a rod, extending to the outside of the car, the catchplates a a arespread so as to liberate the head, f, of rod O.

The coupling-rod O is formed with pointed head, f f, and hole, N, in each end, to receive the coupling-pin when working in connection with the common-linkcoupling', the rod retaining its width immediately beyond the neck h h, and by coining against the sides of the mouth-piece, B, the. rod is kept from adhering to the sides of the catch-platesa a when they are opened for uncoupling. There is also a slight bevel on the inner upright edge of the mouth-piece B, to prevent the rod from catching,'as shown'in-fig. 4.

The head, j; of the rod 0 is bevelled, as shown in Figure 5, so that if any car should turn over enough to correspond with that bevel, the car would be released, thus preventing it from carrying others with it. The coupling-rod, being held by the pair of plates in one head, is thus presented to the apertln'e of the other when the cars to be coupled are brought together.

The tapered head, ff, spreads the plates a. a .when

it encounters them, which plates again close upon the shank h, behind the head, thus catching against the shoulders, g g, of the head, and completing the coupling.

head B, in the rear of the plates to a, by means of the projections it, and sustained against the encounter of the coupling-rod G by the spring E, affixed to theback of the said buffer-plate, as shown. It is intended to soften the concussion of the cars, and also to assist in keeping the rod horizontal, ready to enter the opposing coupling-head.

- These coupling-heads, being attached to the car in the ordinary way, and with the ordinary gum spring behind them, will receive the body of the concussion, allowing the plate D to receive and'soften the blow at the point of the couplinggod C, and not the entire shock of the cars.

Having thus described my invention,

What I claim asfnew, and desire to secure by Let- The above specification of my invention signed by me, this 12th day of June, 1868. v
