Abstract
There is disclosed in the present application a windmill including a wheel having a set of fixed blades and a set of movable vanes whose angular orientation with respect to the axis of the wheel is adjusted automatically for limiting the speed of the wheel to a safe level in winds of high velocity. The fixed blades may be installed to cause turning of the wheel under generally prevailing winds of a very low velocity. The movable vanes are connected to a speed sensing governor mechanism which changes their orientation from positive through neutral to negative for reducing the speed of the wheel when the wind velocity is excessive and the mill would otherwise reach damaging speeds. In addition, there is disclosed a mechanism for changing the orientation of the vanes from a remote location to stop the wheel. The mill wheel is also constructed in modular segments adapted to being shipped in sections and assembled at the operating site.
