Abstract

A safety device for lowering persons or loads from high elevations, such device featuring a revolving cylinder which is selectively coupled to a rope drum or wheel when the velocity of the drum is sufficiently great. The cylinder is mounted on a single shaft and encloses a centrally located or middle piston which is pinned to the cylinder and serves as a partition to divide the inner chamber into two portions. The middle piston is movable rotationally with the cylinder but is immovable axially. Two other pistons within the respective chamber portions are fixed to the immovable shaft but they are movable axially. All of the pistons are propeller shaped; that is, they are contoured to have high and low points; and the inner end walls of the cylinder are correspondingly contoured or shaped.
