ABSTRACT:
A sliding gate structure for controlling discharge of material from openings defined at a lower end of a railroad hopper car. The openings are covered by a pair of gates which linearly move in guide tracks to discharge the material inside or outside of the rails depending on which gate is operated. Each gate is independently operated by an operative mechanism including a control system operable from a side of the hopper car. Each operative mechanisms include a pair of linkage assemblies which are operated by a linearly distendable driver. The linkage assemblies are connected to opposite sides of the respective gate to inhibit skewing of the gate relative to the guide tracks during gate movement. Movement of each gate is independently controlled through actuation of the control system from the side of the hopper car.
