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.
A windmill powered generator comprising:
A windmill powered generator system comprising an elongated frame member, a plurality of rotary wind operated members carried by the frame member, each said wind operated member comprising a crankshaft operably connected to the wind operated member for rotation therewith, a crank arm connected to the crankshaft, the outer end thereof being offset from the rotational axis of the crankshaft, an elongated rotary power drive shaft rotatably carried by the frame member and spaced from the plurality of crankshafts of each of the wind operated members, a plurality of frictional hub members connected to the drive shaft for rotation therewith, there being one said frictional hub member associated with each crank arm of the plurality of wind operated members, a plurality of elongated flexible line members, the first end of each line member being operably connected to the outer end of a crank arm, said flexible line member being passed around one side of the associated frictional hub member and including means for yieldably securing the second end of each frictional line member.
