  • Patent number: 4353312
    Abstract: A bottom discharge hopper rail car has a hopper body mounted on a chassis which is itself supported on flanged wheels. The body has a pair of downwardly converging, laterally spaced side walls with longitudinally extending lower edges which border a discharge opening. The spacing between the lower edges of the sidewalls is greater than the lateral distance between the wheels as wider openings can facilitate discharge. In practice, the wheels have outer flange surfaces adjacent to rail-engaging surfaces for resting on the rails, and the spacing between the lower edges of the side walls is preferably greater than the distance between these outer flange surfaces. The side walls are asymmetrical with respect to a longitudinal vertical plane passing centrally between the wheels as this can inhibit bridging during discharge.

  • Patent number: 4331083
    Abstract: A drop center railway car is provided with a continuous center sill having a depressed portion between the wheel assemblies. The continuous center sill is disposed between a pair of light weight side walls which include side sills that are connected to transverse bolsters for proportionally distributing longitudinal and vertical loads between the two walls and the continuous center sill with the center sill supporting about three-quarters of the longitudinal load. Crossbearers cooperate with the bolsters to prevent injurious bowing of the commodity confining surfaces of the light weight side walls, side sills and bolsters, which light weight is made possible by the forces being proportionally distributed between the three, rather than two, longitudinal members.

  • Patent number: 3938861
    Abstract: A hopper bed for grain or the like is provided by the present invention. An opening in the hopper bed is closed by a flat plate structure which is mounted on first and second track components disposed on either side of the opening. A flat flange portion is coupled with the structure on each side in longitudinal alignment with a track component. Each flange portion has a plurality of closely spaced aligned openings which are also aligned with two spur gears. The spur gears are rotated to mesh with the gear track presented by the openings in the flange and thereby reciprocate the plate structure to close or open it. This construction precludes the accumulation of most foreign material in the gear track although any which does accumulate is cleaned out by the action of the gear itself moving in the track.
