Revendications

Claim 1st The valve E or its equivalent operated by suitable mechanism, and arranged to admit steam or other operating medium to the cylinder of an engine, say, during that portion of the stroke indicated on the crank diagram, from 1 to 2 and from 3 to 4. 2nd The valve E or its equivalent arranged to permit the steam or other operating medium of an engine or motor to pass from one side of the piston to the other, producing an equilibrium of pressure on each side of the piston, during that portion of the revolution of the crank indicated say from 2 to 3 and 4 to 1. 3rd The process of utilizing the exhaust steam or other operating medium of an engine or motor, the said process consisting in exhausting the steam from one side of the piston to the other, at or before the termination of the piston's stroke for the purpose of reducing the amount of live steam necessary to be supplied to the cylinder on the next stroke. 4th The valve J placed on the exhaust side of an engine or motor, for the purpose of preventing the admission of air or other matter into the cylinder or connections, and for the purpose of retaining heat in the cylinder, condenser and connections, and also for the purpose of obtaining hot feed water, or for the purpose, if desirable, for ex-hausting a portion of the steam into the boiler or elsewhere. 5th A chamber B into which steam or other expansive matter is expanded from the generator through a variable pressure valve, before it is admitted to the engine or motor. 6th A condenser having pipes or chambers through which the feed water drawn from said condenser is passed for the purpose of re-heating the feed water before passing it into the boiler. 7th The combination of generator with variable expansion valve, expansion chamber, engine or motor with valve E or its equivalent, condensing and heating chamber, waste pipe and exhaust pipe, provided with a valve J or its equivalent. 8th The waste pipe K1, condensing chamber C2 and hot well K, arranged in connection with the exhaust pipe of an engine provided with the valve J, for the purpose of obtaining a supply of hot water from the condensation of the exhaust steam.
