ABSTRACT:
An apparatus for closing a chute includes a chute for dispensing a granular material. A gate assembly is mounted for controllably opening and closing the chute and includes a bridge member with a curved gate attached to it. The gate assembly is movable between a first position and a second position. In the first position, the gate permits granular material to be dispensed through the chute and in the second position, the gate co-acts with a sealing member and the chute to prevent material from passing through the chute. In a highly preferred embodiment, the sealing member comprises a plurality of inwardly projecting curved ridges formed on the interior of the chute.
