PERPETUAL MOTION. The differential hydrostaticA, B, C, D are four vessels connected to the wheels, E, by roundpins which project from the vessels on eachside, and enter into corresponding holes inthe wheels E. The wheels, E, are in-tended to revolve by the space under thevessel, B, being a vacuum, and thereforelighter than the same portion of air; a lit-tle before the vessel, B, reaches the high-est point of the wheels, it begins to close,and opens the opposite vessel, D, in thesame manner as the vessel, C, opens A, be-cause the pressure of the atmosphere on thevessel, C, is equal to the pressure on of common packing to make thevessels air-tight, mercury is substituted, which has less friction, and is. 372 PERPETUAL MOTION. never out of order. The particles of mercury not being entirely freefrom friction, a little power is requisite to open and shut the vessels;this is expected to be effected by the rods, F, connected to the lever, G,by chains. The rods, F, give motion to other rods, H, by the rollersacting against collars on the rods, H, not shown. The levers, G, are successively worked by sliding over the roller connecting rods, H, are so adjusted as not to draw the vessels out oftheir upright position, which would let the mercury escape; also, thelower vessels, A and D, are made rather larger in diameter than B, C,so that the pressure of the atmosphere may counterpoise the weight ofthe vessels.
