ABSTRACT:
This windmill head comprises a stub tower having a rotatable platform carrying a wind driven fan which drives a transmission mechanism. The mechanism has two cranks and pitman arms at opposite sides driving two rocking beams carrying counterweights. One beam is coupled to a vertical pump rod by non-rigid members to reciprocate the pump rod. The counterweights assist the beams in pulling up the pump rod and pumped load. A tail assembly tracks the wind by rotating the platform so that the fan faces the wind. The fan furls out of the wind when wind speed is excessive. A power unit may drive the transmission mechanism when wind speed is too low and high to drive the fan. The platform is carried by bearings which prevent vertical movement of the platform and components on it while the pump rod is being pulled up and pushed down, and while the counterweights are raised and lowered. The power unit can generate electric power when the wind speed is high enough to drive the fan.
