the several parts of my coupler can be made A I am aware that minor changes in the construction, arrangement, and combination of and substituted for those herein shown and described Without in the least departingr from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a car-coupler of thelink-and-pin type, the combination with the draw-head formed with a lateral opening and provided with a plurality of parallel cam-faces in said opening, which are of uniform inclination and height. of a supporting-block for the pin, provided with a plurality of corresponding cam-4 faces, and means for limiting the outward movement of the supporting-block, substantially as described.

2. In acar-couplerof thelink-andpin type, the combination with the draw-head formed with a lateral opening provided with a plurality of cam-faces d and shoulders a of uniform inclination and height, of a supportingblock provided with a plurality of cam-faces d and shoulders c of uniform inclination and depth cooperating` with the cam-faces and shoulders of the draw-head, and a bolt or projection E, operating in a notch in the upper face of the supporting-block, substantially as described.

3. In a car-coupler of the link-and-pin type, the combination with the draw-head formed With a lateral opening provided With a plurality of cam-faces and shoulders, of a supporting-block D formed with an inclined upper face and a nose which is adapted to sustain the pin of the coupler in an elevated position when the supporting-block is at the in- Ward limit of its movement, said nose being of such length that, when the link of the coupler is introduced to force the supportingblock away from the pin, andthe pin engages the link, said nose Will contact with the pin and hold the supporting-block in an. elevated position, out of contact with the link, substantially as described.

In testimony whereof I hereunto afliX my signature, in the presence of two Witnesses, this 5th day of September, 1898.
