Claims26
A yoke for a railway car, the yoke comprising:
- an open front end configured to receive a coupler shank therethrough;
- a rear wall opposite the open front end;
- two walls connecting the open front end with the rear wall;
- a coupler support extending from an interior surface of one wall from the two walls into an interior space of the yoke between the open front end and the rear wall;
- and
- a wear plate attached to the coupler support, the wear plate having two flanges defining a u-shape of the wear plate, the two flanges being spaced from each other, on the coupler support, in a longitudinal direction of the yoke, a surface of the wear plate positioned to contact a surface of a coupler shank.
