  • Patent number: 4064810
    Abstract: A railway car door includes an operating mechanism having a pair of pipes and cranks rotatably secured to the door. By their rotation, the door is movable into and out of a door opening. The car is equipped to have internally-projecting lading restraining members removably attached to the inside car sidewall and filler members removably attached to the inside of the door. Pipe stops are provided for selectively increasing or decreasing the amount of rotation of the pipes and cranks possible so that when the filler members are attached to the door, the door can be moved laterally out of the opening a first greater distance and thereby permit the filler members to clear the sidewall or adjacent door of the car. When the filler members are removed, the door can be moved a second, lesser distance out of the opening and clear of the sidewall or adjacent door of the car.
