WIND MOTORS

|  | F03D |
Note(s) In this sub-class: The following words are used with the meanings indicated: "Wind motor" means a mechanism for converting the energy of natural wind into useful mechanical power, and the transmission of such power to its point of use. "Rotor" means the wind-engaging parts of the wind motor and the rotary member carrying them. "Rotation axis" means the axis of rotation of the rotor.
