ABSTRACT:
An internal combustion engine or like apparatus is disclosed utilizing an "ellipsograph" mechanism for converting the reciprocating motion of one or more pistons into rotational motion of an output element. The apparatus includes an orbital crankshaft coupled to the pistons by connecting rods and linear slide mechanisms and providing power to an output shaft through one or more crank and gear assemblies. Counterweights on the orbital crankshaft and crank and gear assemblies compensate for inertial forces and unbalancing moments.
