Abstract
A windmill driven pump having rotatable windmill vanes attached to a turning shaft. A disk is eccentrically mounted on the shaft so that both the disk and shaft rotate along with the vanes. Bearings selectively cooperate with the disk to transfer the rotational movement of the disk to a reciprocally movable beam. A pulley system transfers the movement of the beam to a sucker rod for a pump. A locking device is also provided which can prevent the bearings from cooperating with the disk and thus disengage the pump from the rotation of the windmill.
Claims12
A windmill comprising;
- support means carrying a rotatable shaft;
- a plurality of rotatable wind driven blades carries by truss means disposed within a plane and attached to said shaft;
- a disc attached to the truss means for rotation therewith, where the plane of the disc is parallel to the plane of the truss means and where the center of the disc is spaced apart from the axis of rotation of the shaft;
- reciprocally movable follower means operably coupled to the perimeter of the disc;
- means restricting the movement of the follower means to a path in a plane which passes through said shaft.
