摘要： A railcar hatch cover assembly having at least first and second covers each moveable between an open position and a closed position. First and second gears are mounted to the first and second covers, respectively. Third and fourth gears are mounted to a shaft that rotates between first, second, third, and fourth positions in sequence. The third gear is engaged with the first gear as the shaft rotates from the first position to the third position, and the fourth gear is engaged with the second gear as the shaft rotates from the second position to the fourth position. As the shaft rotates from the second position to the third position, the first cover assists in rotating the shaft and opening the second cover. The hatch cover assembly may have any number of covers, which as they move to an open position assist in the opening of another cover.
摘要翻译： 一种轨道车厢盖组件，其具有至少第一和第二盖，每个盖可在打开位置和关闭位置之间移动。 第一和第二齿轮分别安装到第一和第二盖。 第三和第四齿轮安装到依次在第一，第二，第三和第四位置之间旋转的轴上。 当轴从第一位置转动到第三位置时，第三齿轮与第一档啮合，当第三档位从第二位置转动到第四位置时，第四档与第二档啮合。 当轴从第二位置旋转到第三位置时，第一盖有助于旋转轴并打开第二盖。 舱口盖组件可以具有任何数量的盖，当它们移动到打开位置时辅助另一盖的打开。

摘要： A hopper car gate with a frame having multiple openings and one or more solid sections positioned between adjacent openings, an operating mechanism coupled to the frame, and a door supported by the frame. The door has multiple solid sections to match the number of openings in the frame and one or more openings positioned between adjacent solid sections. The door is movable by the operating mechanism between a closed position, in which the solid sections of the door block the openings in the frame, and an open position, in which the openings in the door are aligned with at least some of the openings in the frame and the solid sections of the door are aligned with at least some of the solid sections of the frame.

摘要： A railcar hatch cover assembly having a cover, a latch engaging structure, a latch coupled to the cover, and a handle coupled to the latch. The handle is configured to be grasped by an operator. When a substantially vertical force is applied to the handle, it moves the latch from a latched position to an unlatched position and moves the cover from a closed position to an open position. When the cover is dropped from the open position to the closed position, the latch contacts the latch engaging structure and moves from the unlatched position to the latched position. A railcar latch assembly having a latch coupled to the cover and a handle coupled to the latch. The latch has an arcuate bottom surface that contacts the latch engaging structure to move the latch from an unlatched position to a latched position.

摘要： A hopper car gate with a frame, a door supported by the frame and horizontally moveable between open and closed positions, a rack mounted to the door, and first and second shafts supported by the frame. A first gear mounted to the first shaft engages the rack. Second and third mating gears are mounted to the first and second shafts, respectively. A hopper car with first and second hopper car gates mounted to first and second hoppers, respectively. Doors of the gates move horizontally to an open position in opposite directions from each other with shaft rotation in the same direction. A hopper car gate opening and closing system including a hopper car gate with a pair of shafts, a gear mounted on each shaft, and racks that are positioned to engage the gears as the gate moves with respect to the racks.
