Abstract
A slide gate closure has a frame that is adapted to be mounted to a bottom of a bottom discharge container over the discharge opening at the bottom of the container. A slide gate is slidably mounted to the frame such that the slide gate is configured to move selectively between a closed position, in which the slide gate fully covers the discharge opening, and an open position, in which the slide gate does not fully cover the discharge opening. The slide gate closure further has a lever and a linkage that operatively connects the slide gate and the lever such that operating the lever in a first direction causes the slide gate to move in direction toward the open position and operating the lever in a second direction causes the slide gate to move in a direction toward the closed position.

A slide gate closure for a bottom discharge bottom-discharge container having a discharge opening, the slide gate closure comprising:
- a frame adapted to be mounted to a bottom of the container;
- a slide gate slidably mounted to the frame such that the slide gate is configured to move selectively between a closed position, in which the slide gate fully covers the discharge opening, and an open position, in which the slide gate does not fully cover the discharge opening;
- a lever;
- a linkage operatively connecting the slide gate and the lever such that operating the lever in a first direction causes the slide gate to move in direction toward the open position and operating the lever in a second direction causes the slide gate to move in a direction toward the closed position;
- and
- the linkage having a first hinge plate and a second hinge plate, the first hinge plate pivotally connected the slide gate, and the second hinge plate pivotally connected to the first hinge plate, pivotally connected to frame, and operatively connected to the lever.
A slide gate closure for a bottom-discharge container having a discharge opening, the slide gate closure comprising:
- a frame, the frame defining an inlet open on one side and defining an outlet opening on side opposite of the inlet opening, the frame adapted to be mounted to a bottom of the container with the inlet opening aligned with the discharge opening of the container;
- the frame having a pair of slide rails located on opposite sides of the outlet opening;
- a slide gate slidably supported at opposite sides thereof by the slide rails such that the slide gate is configured to move selectively between a closed position, in which the slide gate fully covers the discharge opening, and an open position, in which the slide gate does not fully cover the discharge opening;
- a lever, the lever being pivotally mounted at one end thereof to a fixed structure and the opposite end of the lever being free such that the lever is rotatable relative to the fixed structure;
- a linkage operatively connecting the slide gate and the lever such that rotating the lever in a first direction causes the slide gate to move in direction toward the open position and rotating the lever in a second direction causes the slide gate to move in a direction toward the closed position;
- and
- wherein the linkage has a connecting rod, a first hinge plate, and a second hinge operatively connecting the slide gate to the lever;
- and
- wherein the connecting rod is connected at one end thereof to the lever and connected at an opposite end to the second hinge plate the first hinge plate and the second hinge plate are connected for relative rotation therebetween, the first hinge plate is hingedly connected to the slide gate and is hingedly connected to the second hinge plate, and the second hinge plate is hingedly connected at one end to the frame and is further hingedly connected at a second end to the hinge plate.
A sliding gate closure for a bottom-discharge container having a sidewall and a bottom coupled to the sidewall, the bottom defining a discharge opening configured to permit material to exit the container, the slide gate closure, comprising:
- a frame attached to the bottom of the bottom-discharge container;
- a slide gate slidably mounted to the frame such that the slide gate is configured to move selectively between a closed position, in which the slide gate fully covers the discharge opening, and an open position, in which the slide gate does not fully cover the discharge opening;
- a lever, the lever pivotally mounted to the sidewall of the bottom-discharge container;
- a linkage operatively connecting the slide gate and the lever such that rotating the lever in a first direction causes the slide gate to move in a direction toward the open position and rotating the lever in a second direction causes the slide gate to move in a direction toward the closed position;
- and
- wherein the linkage has at a hinge plate, the hinge plate is operatively connected to the slide gate to pivot relative to the slide gate, is pivotally connected to the lever, and is pivotally connected to the frame.
