A vertical axis windmill, having a plurality of propelling blades, or vanes, supported in a vertical position by horizontal support bars extending outward from a rotatable tube concentric with a main support pipe. In operation the blades remain down-wind or at an angle to the wind, and are never flat side to the wind. A cam controlled by a wind vane operates a linkage that acts to position the blades to the proper angle. Each blade is supported on a shaft that has a crank arm attached, and a device is provided to rotate the arm past center. Spring pressure is equalized on the cam rollers to reduce the reaction of the cam on the wind vane. The blades are wind directional and act somewhat as a wind vane. As the wind load on a blade increases, the angle of the blade changes and the blade adjusts itself to maintain a regulated rotating speed for the windmill.

A vertical axis windmill, comprising a vertical support pipe, a drive tube rotatably mounted on said support pipe, a disc attached to the top of said drive tube, a plurality of horizontal support bars extending outward attached to said disc, a rotatably mounted vertical shaft at the end of each said support bar, a crank arm attached to the top of said vertical shaft and a propelling blade fastened to the lower part of said vertical shaft, a cam tube rotatably mounted on said support pipe above the said drive tube, means for mounting a cam on said cam tube, a wind vane fixed to said cam tube for rotating said cam tube in response to a change in the direction of the wind, means for supporting a plurality of oscillating arms, a cam roller mounted on the end of each said oscillating arm, said cam rollers bearing against said cam by a spring means, means for mounting a connecting rod to each cam roller shaft, a slide plate attached to the other end of said connecting rod, a “past center device”connecting said slide plate to said crank arm, to translate the reciprocating motion of the said connecting rod, to rotary motion of said crank arm, said vertical shaft and said propelling blades that rotate on their axis in the opposite direction to the rotation of the windmill, the assembly of these parts and the motion of the linkage, through the said “past center device”, deriving from the contour of said cam act to position said propelling blades to the proper angle to produce rotation of the windmill and the proportions and shape of said propelling blades are such as to produce a driving force and a small amount of wind directional effect that together with the designed load of said spring means act to provide a maximum speed control of the rotation of the windmill, therefore if a wind force on said propelling blades exceeds the said load of said spring means the angle of said propelling blade changes thus reducing the said driving force and maintaining the designed rotating speed and as each said propelling blade is independent of the others, a strong wind gust can feather any blade immediately to avoid damage, and as the wind force abates the said propelling blade resumes its normal position as all said propelling blades are in continuous control by the mechanism through the full rotation of the windmill.
