Description: |
| Claim:
This invention relates to improvements in io explosive-gas engines of the well-known class in which the reciprocating pistons have their working strokes as driven by the explosion of the gas ignited in the cylinders alternately that is, in which each piston is positively driven forward by the exploded gas, returned expelling the dead gas, moved forwardly again to draw a new supply of gas into the cylinder, and then again forwardly driven by the next explosion of the gas. In engines of this character usually the main or driving shaft of the engine has two rotations to every working or explosion stroke of each piston, anid it is required that once in every two rotations of the shaft an electric circuit will be made and broken to produce an igniting-spark in the explosion-chamber or an extension or continuation thereof for each cylinder, and also once in each two turns of the shaft, but at a different period from the said circuit closing ;o and breaking, the exhaust-valve will be positively opened to permit seasonably the discharge of the dead gas on the return stroke of the piston following the working stroke effected by the closing of the circuit whereby the igniting-spark is made. |
