Abstract
A slide gate includes first and second frame members, first and second nozzles, first and second plates, a biasing member, a hinge and an actuator. The first plate is connected to the first frame member. A passageway in the first nozzle is aligned with an opening in the first plate. The second plate is connected to the second frame member. A passageway in the second nozzle is aligned with an opening in the second plate. The biasing member includes a channel having a shaft extending through a spring located in the first frame member. The spring biases a retainer and the channel toward the first frame member. The second frame member includes a portion that rides in the channel. The actuator moves the second frame member along the channel to align the nozzle passageways to allow material to flow through the slide gate.
