ABSTRACT:
A wind machine has a tower frame formed by four converging beams. At the top of the tower is a gear head connected to a wind driven rotatable multibladed rotor. Connected to the gear head is a vertical shaft which is reciprocated vertically as the rotor rotates. Bearings above and below the gear head enable the gear head to drive the shaft in both downward pushing and upward pulling modes. The system includes a counterbalance assembly having tubular arms at opposite sides of the vertical shaft. The arms are slidably carried by sleeves pivoting in vertical planes on stationary pillow blocks secured to the tower frame. Inner ends of the arms are connected to the vertical shaft. Weights inside the arms are adjustably positioned on threaded rods, and both rods and weights can be locked in place for adjusting the counterbalancing effect of the assembly with respect to the vertical shaft and load. The system can operate at wind speeds ranging upwardly from approximately 3 miles per hour and can operate to drive loads in both downward pushing and upward lifting modes.
