Description: |
| Claims:
Having thus described an organized and operative engine in which the several features of novelty of my present invention are illustrated and are shown in combination, I specifically claim and desire to secure by Letters Patent the following:
1. The method substantially herein described of operating a gas-engine, which consists in compressing the charge by an independent compressor and controlling the speed of said compressor by means of the pressure of the charge so compressed.
2. The method substantially herein described of operating a gas-engine, which consists in compressing a charge into a reservoir and in controlling the speed of the engine by variations in the pressure of the said compressed charge.
3. The method substantially herein described of operating gas engines in series, which consists in compressing the charge by an independent engine, operating said engine by a portion of the charge so compressed, and operating one or more additional engines by the other portions of said charge.
4. The method substantially herein described of operating a gas engine, which consists in supplying a compressed charge, effecting the compression of the charge by the use of a part of said charge, and controlling the amount of such compression at an inverse ratio to and by the pressure of the charge.
5. The method substantially herein described of operating a gas-engine, which consists in compressing the charge by an independent compressor, controlling the speed of said compressor by closing the exhaust at various points in the back-stroke of the piston of the same, and determining such points of closing in accordance with the degree of compression of the charge.
6. The method substantially herein described of operating a gas-engine, which consists in compressing the charge by an independent compressor, controlling the speed of said compressor by closing the exhaust at various points in the back-stroke of the same, thus cushioning said back-stroke by the compression of the waste gas, and controlling the duration. of such closing or cut-off in a corresponding ratio to and by the pressure of such charge.
7. The method substantially herein described of operating a gas-engine, which consists in compressing the charge by an independent compressor, operating said compressor by a part of the compressed charge, controlling the speed of said compressor by cushioning the back-stroke of its piston by the waste gas, and controlling the force of such cushioning in a corresponding ratio to and by the pressure of the compressed charge.
8. The method of operating a gas-engine substantially herein described, which consists in opening and maintaining without interruption a free communication between the combustion chamber and a supplemental chamber during the first strokes of the piston at the starting of the engine, whereby to enlarge the compression and expansion area of said chamber, and subsequently closing and maintaining closed said communication while the engine is under way, substantially as described.
