ABSTRACT:
A windmill having a gearbox, tail and wheel is disclosed in which a mast is secured to the windmill and is rotatable as a unit within a mast housing secured to the tower. A pull-out assembly exerts an axial downward force on a pull-out tube concentrically positioned within the mast. A mounting hub on the drive shaft supports the wheel at taper bearing surfaces. The individual sails are adjustably secured to one or more concentric, segmented rings attached to the mounting hub by radial spokes or braces.
