There is disclosed in the present application a wind wheel having a set of movable vanes whose orientation with respect to the plane of the wheel is changed automatically to limit the speed to a safe level in winds of high velocity. The wheel is constructed and shipped in segments and is especially adapted for ease of assembly and truing for minimal eccentricity and lateral run-out.

A windmill assembly including a wind wheel comprising a central hub formed with spaced apart front and rear flanges, a plurality of sub-assembly segments each generally in the form of a circular sector adapted to being assembled around the hub with similar segments to form a complete wheel assembly

A windmill assembly including a wind wheel comprising a central hub formed with spaced apart front and rear flanges, a plurality of sub-assembly segments each generally in the form of a circular sector adapted to being assembled around the hub with similar segments to form a complete wheel assembly and each including a bridge connected to the bridges of adjacent segments and having front and rear edges oriented in the wheel assembly, a radial support extending from the hub and passing through a fitting on the bridge, an adjustably fixed blade mounted on the radial support and a primary movable vane pivotable on an axis in alignment with the radial support, laterally and radially adjustable means for securing the segments to the hub, the wind wheel further comprising a speed sensing mechanism including a plurality of interconnected weights each mounted on an arm pivoted for movement toward and away from the axis in the plane of the wheel, whereby speed related movement of the weights is translated into orientation of the vanes to reduce their torque input from the vanes to the wheel as wheel speed increases.
