Abstract: A vertical axle paddle motor including a support structure with a rotor mounted on the vertical axle, the rotor having a plurality of arms with paddle members pivotally attached to the end of the same. Each of the paddle members include a plurality of adjustable vanes which move from an open to a closed position within the paddle. Vane position in the paddles is controlled by a wind velocity and wind direction control, operating a pair of cams forming a composite cam surface which is engaged by cam followers on each of the rotor arms associated separately with motors on the paddle, to adjust the position of the vanes within the paddles for maximum efficiency in rotation. The wind velocity cam may be adjusted relative to the wind direction cam to increase the amount of time the vanes of the paddles are held in an open position to reduce and stabilize rotation of the rotor.

Abstract: A vertical axis wind turbine comprises one or more aerofoil section blades attached to a support structure. The blade has at least one part thereof which is acted on by centrifugal forces as the blade rotates with the support structure and thereby caused to increase its angle of inclination to the said vertical axis when the speed of rotation increases beyond the normal operating range, whereby the rate of increase of rotational speed with wind speed is reduced.

Abstract: A blade mounting having journal and thrust bearings locating the blades in a hub to relieve load and therefore friction by a torsionally flexible tension member secured within each blade so that centrifugal forces of the blade are transmitted directly to the hub, instead of thru the thrust bearing. Also, each blade is located in the hub so that the aerodynamic torque and thrust on the blade are transmitted directly to the hub as components of the centrifugal force.

Abstract: A wind machine comprising a fixed or controlled pitch blade assembly to drive a variable displacement or variable clearance fluid compressor. Means which may be mechanical, hydraulic, pneumatic or electrical interconnect the blade assembly and the compressor to vary the fluid displacement or clearance volume of the compressor as a function of the drag or lift forces of the wind on the blade assembly.

Abstract: A wind driven prime mover which is driven by a plurality of arcuately shaped wind vanes pivotally mounted on a rotatable turntable. The wind vanes are pivotally mounted on the turntable with their pivot axle disposed in a vertical plane. The pivots are positioned adjacent the periphery of the turntable, with the pivots being spaced equi-distant from each other and equi-distant from the axis of rotation of the turntable. The bottoms of the vanes are arcuately shaped, with the length of the arc being slightly longer than the space between the pivots so that there is an overlap between adjacent vanes. The convex surface of the vanes face outwardly to provide a concave inner surface.

Abstract: A windmill blade that has a rigid leading edge, a rigid root portion and a movable blade tip. Control of the geometric twist of the windmill blade is accomplished through proper selection of the axis of rotation for the movable blade tip and by controlling the position of the windmill blade tip with a servo motor or by controlling the position of the windmill blade tip with a spring and a weight. The ability to vary the geometric twist of the blade enables the frequency of rotation of the blade to be controlled to reduce wind drags upon the blade. This improved windmill blade eliminates the need for current complicated and expensive rotor hubs which are used to vary the blade pitch angle at the root end of the blade to reduce wind drag upon the blade. Processes related to the windmill blade are also presented.
