Hydrostatic Bellows

Hydrostatic Bellows, an arrangement on the same principle as the hydraulic press, by which a heavy weight distributed over a large area may be lifted by the pressure of water produced in a small verticed pipe. The weight is supported on a large board that forms the cover of an ordinary bellows. As water is poured down the small pipe the bellows gradually dilate and the weight is lifted.
