Abstract
A wind driven blade is pivotally carried by a rotatable crank arm. The blade rotates relative the crank arm from a position perpendicular to the wind during the power stroke to a position parallel to the wind during the return stroke. The moving mass is dynamically balanced to provide a self-contained single blade modular unit. A selected number of the modular units are adjoinable to form a multi-blade wind motor in which any given module may be functionally disconnected.
Claims10
A wind motor for receiving the force of the wind and for translating the generally linear movement thereof to rotary motion, said wind motor comprising:
- (a) a stationary frame;
- (b) a crank member including
- (i) a crank shaft journalled in said frame for rotation about a first axis, and
- (ii) a crank arm extending radially from said crank shaft;
- (c) a wind blade carried by said crank arm and rotatable about a second axis spaced from and parallel to said first axis;
- (d) timing means for maintaining a predetermined ratio between the speed of rotation of said wind blade about said second axis and the speed of said crank shaft about said first axis;
- and
- (e) balance means rotatable in response to rotation of said crank member for dynamic balance of the moving mass of said wind motor,
- whereby said wind motor is self-contained, single blade, modular unit.
