Rotating piston engine with constant torque arm drive of its power take-off shaft

A two cylinder rotary piston internal combustion engine, including in combination:

• two interengaging piston-cylinder assemblies, both cylinders and pistons being arcuate in shape for movement around a circle on an engine plane, the piston of each assembly and the cylinder of the other assembly reciprocating with respect to each other,
• a rotary power take-off shaft on one side of and perpendicular to said plane,
• a rotary flywheel shaft coaxial with said power take-off shaft and perpendicular to and on the other side of said plane therefrom,
• a flywheel mounted on said flywheel shaft,
• two separate rotary, at least partly hollow, cylinder support shafts for each said piston-cylinder assembly, one on each side of said plane, and perpendicular to said plane, each rigidly attached to its piston-cylinder assembly,
• the two said cylinder support shafts on the take-off side of said plane being concentric with said take-off shaft and surrounding it, the support shaft for one said piston-cylinder assembly being larger than and surrounding that for the other, the three said shafts being rotatable relative to each other and supporting each other, but not connected to each other,
• the two said cylinder support shafts on the flywheel side of said plane being concentric with said flywheel shaft and surrounding it, with the shaft for one said piston-cylinder assembly surrounding that of the other, these three said shafts being rotatable relative to each other and supporting each other, but not connected to each other,
• a stationary engine casing surrounding said piston-cylinder assemblies and all said support shafts, and having bearings supporting the outer said shafts for rotation, with said flywheel shaft and said power take-off shaft extending out therefrom,
• a first clutching system on the power take-off side of said plane having means for clutching, in alternation, each of the two support shafts on that side of the plane to said power take-off shaft, only one said support shaft at a time being clutched to said power take-off shaft, and for enabling rotation of said power take-off shaft in a single direction and also for enabling rotation of each piston-cylinder assembly in a single direction,
• a second clutching system on the flywheel side of said plane, having means for clutching, in alternation, each of the two said support shafts on that side of the plane to said stationary casing and for preventing reverse rotation of those support shafts, and the cylinders, and
• transmitting means for imparting drive from said piston-cylinder assemblies to said flywheel shaft and vice versa, in alternation,
• whereby at any time two different strokes are taking place simultaneously, each involving the piston of one said assembly and the cylinder of the other, each said piston-cylinder assembly moving alternately with the other.
