ABSTRACT:
An escape device for lowering an escapee trapped in the upper stories of a burning building, including a cylindrical casing in which is mounted a rotatable drum having a wire wound therearound with one end attached thereto. The casing is provided with an escapee-supporting member mounted externally thereto and a feed-through hole by which the other end of the wound wire exits the casing and can be secured to the building. The drum is provided with a gear on the inner peripheral surface thereof, which gear is in meshing engagement with a reduction gear unit also supported within the casing. One gear of the reduction gear unit is mounted on a shaft which also has mounted thereon a brake disc member. Brake arms having brake shoes facing the brake disc member are mounted exterior to the casing and are manually operable to control the rotation rate of the reduction gear unit, and therefore of the rotating drum, whereby the descent rate of an escapee supported in the escape member attached to the cylindrical casing is safely controlled.
