• the Polish patent No. 25 034 presents wind motor consisting of a cylinder mounted on a vertical axle with fixed on the surface thereof axles, which are parallel to the axle of the cylinder, movable wings, having a curvature same, as the curvature of the cylinder surface. Each of the wings covers the adequate part of that surface. Operation of the motor lies in the fact, that in the resting position, under pressure from springs the wings line up radially in the direction of the axle of cylinder, applying pressure of its convex side to supports. Under the pressure of the wind rotation is caused by a blow to the concave surface of the wing, held in the radial position while the convex surfaces of the wing are pressed to the surface of the cylinder.
• Rotation of the ring causes a rotation of the control ring; thereby the sliders through the yokes are causing rotation of the vertical axles with the sails.
