ABSTRACT:
This invention relates to a hydraulic jack that is comprised of a cloth protected inflatable bladder surrounded by a structure that contains and directs the force and motion of the bladder in one direction. The bladder is inflated and pressurized by tap water that is fed to it by a garden hose. This hydraulic jack is unique in that it uses a garden hose and tap water to connect and power it, in that it uses a continuous bladder to make it inherently fluid tight, in that it is of simple enough construction as to be relatively inexpensive to produce and easy to maintain, in that it is for operating purposes, massive enough in volume and section to produce ample strength, and ample stability in load balance.
