Abstract

Novelty: deployment and retraction of a triangular sail operating as a wind mill blade. Constitution: an electrically-operated motor 9 causing the rotation of the stock 5 about its lengthwise extending axle whereon the one side of the sail is lengthwise screwed; the corner 13 of the sail is fastened at the suited point 14 on the wire rope or string 12 which moves on the perimeter of the propeller, in a straight way between two successive sails with the aid of the rowls 15 and is wound inside the reel 8 which is positioned on the stock 5 at the propeller’s perimeter, in homoaxial relationship to said stock.
