ABSTRACT:
An outlet gate assembly for a hopper type railway car includes a frame adapted to be mounted on an outlet opening in the rail car and a plate in the frame. An integrated rack and pinion drive moves the plate between open and closed positions on the frame. The drive includes a drive shaft, slip sockets mounted on the ends of the drive shaft and connected to the drive shaft through lost motion connections, pinion gears mounted directly to the drive shaft and rotatable with the drive shaft, racks mounted on the plate engaging the pinion gears so that rotation of the drive shaft moves the plate between the open and closed positions and a latch actuated by movement of either socket for latching the plate in the fully closed position and unlatching the plate prior to rotation of the drive shaft to open the plate.
