Description: |
This engine was improved with Patent #395,039.
Abstract:
My invention relates to that class of engines having two rectangular pistons adapted to work in a case, said pistons acting together conjointly for the purpose of producing a revolution of the main shaft, the construction being such that the pistons themselves act as valves in operating the engine.
Claim:
In a double-acting square-piston engine, the combination of an outer shell adapted to enclose two pistons, a piston adapted to have a reciprocating motion within the shell, and an inner piston having a reciprocating motion within the outer piston, said piston moving at right angles to the motion of the outer piston, and said pistons serving as valves. |
