Abstract
A windmill is provided having a flywheel attached to the fan shaft and an upwardly extending crank link which is cranked by crank pin mounted off-center on the face of the flywheel. The crank link rocks a rocker beam which may, for example, actuate a pump. The crank link and pump are pivotably attached by sleeves on the rocker beam whereby the amplitude of the rocking motion imparted to the beam and the pump may be adjusted by adjusting the positin of the sleeves along the beam. Counterweights may be provided on the rocker beam for giving the crank link a pulling or a pushing function.
Claims9
A windmill, comprising:
- (a) a windmill fan,
- (b) a fan shaft having the fan mounted on a front end portion thereof for rotation therewith,
- (c) an upwardly extending mast,
- (d) a ring bearing mounted at an upper end of the mast for imparting relative rotation about an axis extending upwardly to one side of the mast,
- (e) bearing means mounting the fan shaft on the ring bearing for rotation by the fan about a substantially horizontal axis intersecting the upwardly extending axis, while permitting the fan shaft to swivel on the ring bearing relative to the mast about the upwardly extending axis,
- (f) a windmill tail assembly mounted on the ring bearing, and extending rearwardly from the fan for pointing the fan into a wind,
- (g) a flywheel mounted on, and substantially coextensive with, a rear end portion of the fan shaft, for rotation therewith,
- (h) a crank pin mounted off-center on the flywheel with respect to the axis of rotation of the fan shaft,
- (i) a crank link rotatably mounted at an upper end on the crank pin and extending downwardly therefrom through the ring bearing for unobstructed crank oscillation, by the crank pin,
- (j) a rocker beam assembly pivotally supported at an intermediate position along the length thereof to the mast for rocking in a seesaw manner,
- (k) coupling means rotatably and pivotally attaching a lower end portion of the crank link to a driven part of the rocker beam assembly, whereby the rocker beam may be rocked by the crank link,
- (l) connecting means on a driving side of the rocker beam assembly for utilizing rocking motion thereof, and
- (m) amplitude adjusting means for adjusting the amplitude of the rocking motion transmitted by the rocker beam from the crank link to the connecting means.
