  • Patent number: 6619921
    Abstract: A blade assembly for a windmill includes an output shaft with a first cross-shaft and a second cross-shaft operatively mounted relative to the output shaft. The first cross-shaft and the second cross-shaft include a first end and a distal end. A first blade is mounted on the first end of the first cross-shaft and the first cross-shaft is rotated by the first blade to impart rotation to the output shaft. A second blade is mounted on the distal end of the first cross-shaft and the first cross-shaft is rotated by the second blade to impart rotation to the output shaft. Stops are positioned on the first cross-shaft for limiting the rotation of the first cross-shaft relative to the output shaft. A third blade is mounted on the first end of the second cross-shaft and the second cross-shaft is rotated by the third blade to impart rotation to the output shaft.
