Phenix Gazette

The Charleston and Savannah papers contain an account of a machine on an entirely novel principle, invented by a Mr. Prouty, of Augusta.

The power of this ingenious and labor-saving machine, is produced by the alternate expansion and condensation of vapor, which propels a quantity of water from one to the other of two receptacles at the extremity of a tube, which passes along a nicely balanced beam, and communicates with the bottom of the two receptacles, or vessels.

To one of these heat is applied, and vapor consequently produced, which, having no other escape, forces the water along the tube into the other receptacle. This becoming heavier, the end of the beam to which it is attached, is depressed, and the opposite end, of course, elevated. The other receptacle, from which the water had been forced, now remains elevated and filled with vapor, this is speedily condensed by exposure to the air, and a vacuum is soon formed which is filled by a rush of water from the opposite extremity, and the beam returns to its former position over the fire, when a similar action again commences, producing a continued successive elevation and depression of the two ends of the beam.

This power may be applied to the propulsion of boats, saw and grist Mills; and works without the aid of an Engineer.
