Explosive Engine
|
Enoch Prouty |
Chicago, Cook County, IL |
Claim:
Explosive engines, as heretofore constructed, have necessitated the provision of some mneanis for starting the same by moving the pistons in order that they may take in a charge of explosive mixture. This has been accomplished generally by providing a crank arm by which the operator turns over the crankshaft, moving the pistons so that they will take an explosive mixture and so that the mixture will be ignited. Another way of accomplishing the same result has been by the provision of some auxiliary power, generally in the form of fluid under pressure, which is admitted to the cylinders for initially starting the pistons. |
