Description: |
| Abstract:
This invention relates to engines driven by the heat produced by the explosion of a mixture of gas or hydrocarbon vapor with air. Such engines often give trouble in running, owing to the difficulty or practically the impossibility of completely expelling the waste gases formed by the combustion of the mixture in the cylinder. These waste gases remain in the clearance-space of the cylinder, mixing with and thus vitiating each fresh charge of gas and air and sometimes enveloping the ignition device so thickly that the charge fails to ignite properly and the engine is caused to run unevenly. The object of my invention is to provide a means capable of application to any explosion-engine making four strokes of the piston in each cycle, whereby the piston may be forced quite to the head end of the cylinder during the exhaust-stroke, thus completely expelling the products of combustion, while on the compression-stroke the piston stops short of the end of the cylinder, leaving a clearance-space, in which is contained the compressed charge.
Claim:
An explosive-engine comprising a reciprocating member, such as a piston, having a nearing-face, a coupling member jointed to the connecting-rod or part which receives motion from the piston and adapted to stand it different angles with the connecting-rod, said coupling member having a complemental bearing-face, and a yielding connection between the two members, whereby a yielding contact is maintained between the said bearing-faces, one of said faces being curved. |
