Abstract
When the slide gate of a hopper car is across the discharge opening and against the part of the frame that defines that opening, each of one pair of abutments below the gate and secured thereto is resting on a respective lever arm which lever arm is generally vertical and secured to the rototable shaft employed as a part of the mechanism for opening and closing of the gate. At the opposite side of the discharge opening from the shaft, the gate has another pair of downwardly facing abutments each of which then is resting on a respective generally vertically lever pivotally secured to the frame. As the gate is initially moved horizontally away from that position the lever arms pivot to permit the gate to descend. In addition to forming the downwardly facing abutments, the parts that form those abutments also form abutments which engage the lever and pivot it to an upright position as the gate is being closed.
