Abstract: An anti-spin/anti-drift or stop mechanism for a railway car door includes a shaft, a helical gear mounted to a first end of the shaft, a helical drive rotatably cooperating with the gear, and a worm gear mounted on a second end of the shaft. The worm gear is disposed in continuous engagement with a gear segment by means of intermeshing gear teeth. A handle for selectively rotating the worm gear is mounted on an end of a helical drive shaft. When the handle is rotated to move the railcar door to a fully opened position, the worm gear rotates the gear segment in a first direction while preventing rotation in the opposite direction to thereby eliminate the potential for drifting of the door. Also, as the handle is rotated to move the railcar door to a fully closed position, the worm gear rotates the gear segment in one direction while preventing rotation in the opposite direction to eliminate the potential for spinning of the handle.

Abstract: 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.

Abstract: A high cubic capacity railroad boxcar that is provided with a longitudinally extending depressed nailable steel floor section disposed on each side of a longitudinally extending center sill structure, the top surface of the floor sections being at the same elevation as the surface of a plate over the center sill structure, the outside lateral margins of each floor section having a removable inverted filler channel member positioned in a longitudinal runner recess adjacent a car angle member and side sill. Each filler channel member may be replaced with a bulkhead floor track in the form of a slotted runner member or a rack gear member and cooperate with a similar overhead track for receiving, locating and restraining removable bulkheads later added to the car by a lading shipper as may be required.
