ABSTRACT:
The storage silo has a frustoconical discharge chute terminating in an annular outlet member having an inflatable bladder about its margin. A gate is movable horizontally and, when in the vicinity of the opening near its closing position, movable both horizontally and vertically into engagement with the margin of the cylindrical wall member. The bladder is then inflated to engage the gate sealing between the outlet and the gate. To open the outlet, the bladder is deflated to a location above the margins of the opening whereby the gate may be moved vertically downwardly and horizontally away from the opening to discharge material from the silo.
