ABSTRACT:
A single circular or cylindrical door is provided which covers a pair of horizontal discharge openings in a hopper car construction transversely of the longitudinal axis of the rail car. Each circular or cylindrical door is pivotally mounted to the rail car body on each side of the rail car. A fluid operated cylinder is connected to each door at the central span thereof. The other end of the fluid operated cylinder is connected to the center sill of the rail car. A directional valve controls the direction of fluid flow to the fluid operated cylinder to cause the door to rotate from a closed position blocking the pair of discharge openings to an open position whereby both discharge openings may simultaneously discharge material from the hopper car.
