Show POWER HEAD FOR WINDMILL One Invented by Montana Man Having Hav-ing Maximum Wind Pressure Surface Sur-face Regulated Automatically. In decrlbing a windmill Invented by C. F. Craddick of Butte, Mont., th Scientific American says: The accompanying Illustration shows a side elevation of a windmill constructed and arranged in accord ance with the present invention. The principal objects in view in this case are: to provide a power head for a windmill disposed and arranged as a series of turbine-shape rotating mem bers; provides a power head having a maximum wind pressure surface disposed dis-posed in proper relation to the wind, and having the maximum of exposed Windmill. surface when disposed in angular relation re-lation to the wind; and to provide regulating means for automatically varying the pressure under operative-conditions. |
