ABSTRACT:
A kinetic energy system for raising and lowering an elevator with pneumatic and hydraulic fluids. The elevator has a platform with a downwardly projecting shaft and a casing for receiving the shaft. A vertically extending control chamber has a vertically reciprocal piston with a supply of hydraulic fluid beneath the piston and a supply of pneumatic fluid above the piston. The piston is movable as a function of the pressure of the pneumatic fluid above the piston. A hydraulic fluid storage tank is coupled to the casing and the control chamber. Hydraulic fluid lines couple the bottom of the control chamber with the casing. Also included are a pneumatic fluid pressure tank, a compressor, a pneumatic fluid-receiving tank, and controls interrelated to effect the desired movements of the platform.
