Abstract
Abstract A device for converting force includes an air pump which pumps air of a wheel separated into chambers by radial vanes and mounted in a body of water. Air is pumped successively into the spaces in a lower quadrant of the wheel to render the same bouyant, and the water and then the air escape therefrom as this quadrant turns upwardly, at the same time exerting a thrust in the direction of rotation. Flaps are provided to permit the rapid inflow of water when the chambers are in the upper quadrants.

Claim 1
Independent Claim
153 words
A device for converting force comprising a wheel immersed in a liquid mounted to turn about a horizontal axis and having spaced end walls and radially extending partitions between said end walls dividing the same into a plurality of chambers, and means to supply gas under pressure to the chamber in a lower quadrant of the wheel, whereby buoyancy imparts an upward movement to said chamber, causing the wheel to rotate, said partitions having openings therein adjacent the periphery of the wheel to permit water and gas under pressure to escape as the partitions into which the gas has been pumped turn upwardly, flap means hinged in each of said compartments on the partition adjacent the periphery of the wheel part at a point closer to the center than said openings, and stop means for limiting outward swinging of said flap means while substantially preventing the escape of fluid past such flap means.
