WIND MOTORS
NOTE
-
In this subclass, 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;
- "Rotations axis" means the axis of rotation of the rotor.
