Abstract: A windmill powered generator having one or a plurality of wind operated motor units, each being operably connected to a single power drive shaft to effect rotation of said drive shaft regardless of the rotational direction of the wind operated rotary units. Each rotary unit is provided with a crank shaft having one or more crank arms carried thereby, the drive shaft having one frictional hub associated with each crank arm. A drive belt extends from each crank arm around its associated hub and is yieldably secured to either the frame or to the end of another drive belt attached to an oppositely oriented crank arm whereby movement of the crank arm in a direction away from the drive shaft increases the friction between the drive belt and the frictional hub causing rotation of the drive shaft and whereby movement of the crank arm in a direction toward the drive shaft decreases the friction between the drive belt and the frictional hub thereby allowing the belt to slip about the frictional hub.
