Abstract
Apparatus for selectively opening and closing a fluid-tight sealing gate for a storage bin or the like. A gate closure member is mounted on a carriage which is supported for lateral movement relative to a material flow opening. As the carriage assembly is laterally moved by a linear actuator, the closure member is moved in a direction perpendicular to the material flow opening to accomplish sealing and unsealing of the opening in proper timed relation with the lateral movement of the carriage assembly. A material flow guiding structure is connected to the carriage assembly for movement into position adjacent the material flow opening, as the carriage assembly is laterally moved to withdraw the closure member from closure relation with the flow opening.
