Description: |
| The inventor was Sir William Congreve, 2nd Baronet, best remembered as the inventor of Congreve rockets, solid-fuel rocket for use in battle."Rotary engine wherein the elastic force of the steam is applied under the pressure of a column of circumambient (surrounding) fluid. A boiler is divided by an horizontal partition into an upper and lower compartment. A third compartment is formed within the upper division by an interspace left between two concentric curved partitions; behind this, between the back of the interspace and the side of the boiler, is a fourth compartment. This chamber or passage is open to the lowest division at an aperture in the horizontal partition, and extends to the roof of the upper compartment; thence turning round, it is continued downward by the interspace between the curved partitions, to an orifice opening into the upper compartment under the buckets of an overshot waterwheel enclosed in it. This chamber is filled with water, and the wheel revolves freely on its axle, and wholly immersed in it. The lower compartment, also filled with water, is fed from the upper by a pipe, but no steam escapes from it. These compartments compose one boiler set in one furnace, surrounded with the same flues, and having the water nearly of the same temperature. The steam from the lowest compartment enters the fourth, and, rising to the top, turns round, and, driving the water before it, forces its way downwards through the interspace between the concentric partitions, and it issues with great velocity into the ascending buckets of the immersed waterwheel, displaces the water they contain, and carries them round with great energy. "In this way a rotary motion is produced, "not acting by impulses, but revolving with a regular and constant "force, without loss of power by friction or refrigeration, and "without valves, pistons, or any of the complex apparatus of "steam engines in use." The displacement of the fluid in the ascending buckets gives a buoyant power on that side of the wheel equal to the actual weight of the water displaced, or to the power exerted by the wheel working in air by the fall of a column of water equal in quantity to the displacement, independent of and in addition to the power acquired from the energy and expansion of the steam..." |
