Abstract
A crankshaft assembly provides a combination of a clutched hollow crankshaft for driving a reciprocating device with a driveshaft for driving another device. The drive shaft extends through the crankshaft and is powered by the same flywheel as is used to drive the crankshaft. The assembly permits selective transmission of power to those devices only when they need power. In the preferred embodiment, the drive shaft provides continuous power while the crankshaft provides power as needed by engaging and disengaging the crankshaft clutch.
