Abstract

The windmill consists of two sets of revolving blades mounted horizontally on either side of a tripod. The blades are mounted on a swivel so that they can face into the wind. The direction is controlled by the wind vane (5). The vanes (11) are mounted on radial arms (9) and are shaped so as to reduce drag on the vanes during the contra-flow part of rotation. The lower blades are protected from the wind by a shield (20) which has an edge towards the wind flow to reduce eddies. The flap on the shield can be lifted during storms to reduce the velocity of the wheel.
