Air transfer in submerged wheel
Air transfer in submerged wheel. A, in the cut, is a tank containing water, as shown. The hollow arms, B, communicate with a hollow shaft, C, and the bellows, E, screw valves, D, being employed to increase or diminish the area of the passages in the hollow arms B.
Each of the bellows, E, carries a weight, which, during a portion of the revolution, compresses the bellows and forces the air out of it through the hollow arms, B, and shaft, C, into bellows upon the opposite side of the wheel, which, being inverted, are expanded by the action of the weights, and, their buoyancy being thus increased on one side of the wheel, the latter is expected to turn constantly by virtue of the effort of the expanded bellows to rise to the surface.
