  • Patent number: 4262601
    Abstract: An arrangement for operating longitudinally disposed discharge door for a railway hopper vehicle includes adjacent pairs of interconnected hopper doors. The doors of each pair are connected by linkages to provide simultaneous, cooperative opening and closing movement. The inner door of each pair is operatively connected with a locking linkage which, when in the locked position, engages a longitudinally displaceable locking cam to secure the doors. Displacement of the locking cam permits the weight of the lading within the car to open the discharge doors. The doors are returned to the closed position by means of door-engaging trackside cams, and the locking cam is returned to the locked position securing the doors.
