Abstract
A portable containment chamber for disposing of explosive threat devices comprises a cylindrical chamber body with a hinged interiorly convex outward-opening access door. The door closes against a tapered seat whereby explosion pressure enhances a gas-tight seal. In closed position the door is locked by interconnected expandable locking shoes which engage an annular locking channel in the mouth of the chamber with a simultaneous crank-and-piston linkage. The door is actuated by a pneumatic mechanism which first traverses laterally it into alignment with the chamber, then traverses it axially into sealing engagement with the chamber mouth, and then moves the expandable locking shoes into locked position. A first interlock prevents axial door movement when in standby position, and a second interlock inhibits detonation of a donor explosive charge within the chamber if the door locking shoes are not fully locked.
