RAIL HOUSE CAR DOOR CRANK MOUNT Abstract of the Disclosure A rail house car with at least one opening along each of its sides. The car includes a door for closing each of the openings by movement of the doors longitudinally along the car sides and laterally into and out of the openings. Bottom and top rotating crank members moveably support and retain the doors on longitudinal tracks below the doors and within longitudinal retainer means above the doors. At least some of the crank members are selectively manually driven by rotational means for selective lateral movement of the doors. The top crank members adjacent the upper portion of the doors each include a bore. A forged pin is telescopingly received in each of a plurality of pipes rotationally mounted on the door, Each pin has a shank portion and an upper headed or flanged portion. Each crank member's bore is counterbored to receive the headed portion of a pin. Substantially the entire periphery of the shank portion is welded to its associated crank member and only a portion of the flange formed by the head of the pin is welded to the crank member counterbore. This minimizes deterioration of the strength given to the pin flange by the forging operation. Alternatively, the head can be spaced from the top of the crank member and only the shank portion welded to it. The crank mount is also for use with any auxiliary crank members which are in engagement with the longitudinal retaining means of the car. A pin or weld or both can secure the extension pin and pipe to prevent relative rotation therebetween. -2-
