ABSTRACT:
A windmill is provided which automatically compensates for increased wind velocity, causing the blades to feather and rotate at a substantially constant velocity rather than overspeeding. This is accomplished by pivotally mounting the blades so that they are rotatable between positions of relatively high angle with respect to the direction of the wind and positions of relatively shallow angle, with a resilient means biasing them to the former position. Tabs projecting forwardly at obtuse angles from the outer ends of the leading edges of the blades cause the blades to be pivoted to the feathered position when wind velocity increases.
