- 18 - WINDMILL ABSTRACT OF THE DISCLOSURE A vertical column is journalled for rotation on a base and a double set of blades are journalled one set upon each end of a cross shaft at the top of a spindle in the column and gear connected thereto. Each set of blades is angled so that the shafts mounting same is situated at right angles to the direction of the wind and in order to prevent the wind acting on the lower blades cancelling out the wind acting on the upper blades, a casing shields the lower blades thus shielding them from the wind and allowing the wind to act directly on the upper blades. A conduit through the casing routes the wind through the casing and reverses its direction so that it impinges on the rear sides of the lower blades thus giving additional turning power to the sets of blades.
