ABSTRACT:
A railroad car with a hopper-type body may include a series of gate assemblies for selective discharge of commodity in the car body. Each gate assembly may have two pairs of doors which rotate to close or open respective outlet openings in the gate assembly. Door rotation is effected by an operating system comprising an air cylinder joined to a series of lever activating devices by a series of connecting rods. Each lever device includes a lever arm pinned to the connecting rods and rotatively carried on a shaft attached to a sill of the car. A crank arm of the device is also carried on the shaft and interacts with the lever arm through a pair of bolts threaded one each to the lever arm and crank arm. Ends of the device crank arms are pivotally secured by connecting bars to adjacent gate door pairs respectively. Relative angular position of each device lever arm and crank arm may be adjusted by selective positioning of the bolts to locate the crank arm in a position where the door pairs remain properly closed, for example, when the air cylinder is not pressurized. To open the gate door pairs the air cylinder is pressurized to move the connecting rods and rotate the lever arms and crank arms of each lever activating device. Crank arm rotation in turn applies a force evenly to the gate door pairs to open same. Door closure is effected by an oppositely applied force.
