Abstract

Abstract The windmill has sails which rotate around their fixture points, and always adopt the most favourable position in regard to the direction of the wind. They can be brought to the best position either mechanically, or indeed by the wind itself, since the mill is located eccentrically and rotatably on its points of support. A column (1) is involved, in which a support arm (2) revolves with the main shaft (3). On the main shaft rotate the locators (4) in which the sail (6) shafts (5) in turn rotate.
