ABSTRACT OF THE DISCLOSURE A windmill is provided for converting wind energy to reciprocal mechanical energy at a pump rod. The windmill includes a housing having a base, a wheel shaft having a first end adapted to receive a wheel and a second end extending into the housing, and a drive gear at the second end of the wheel shaft. A driven gear is in engagement with the drive gear and is rotatably driven thereby. A generally cylindrical lift cam is rotatable with the driven gear, and has a generally vertical axis. The lift cam has an edge defining a circular cam track having a rise and fall with the length of the rise exceeding the fall, the rise being rapid relative to the rise. A walking beam is provided having one end mounted for pivotal movement and having the other end secured to the pump rod. That beam has a cam follower thereon engaging the cam track at a substanti- ally fixed distance from the vertical axis at all positions of the follower, whereby upon rotation of the sheel shaft, gears and lift cam, reciprocating motion is imparted to the rod through the follower. In this way upon ro- tation of the wheel shaft, gears and lift cam, reciprocating motion is im- parted to the rod through the follower and the walking beam, with a generally linear lift being imparted to the rod and a relative fast fall in each rotation of the cam and, whereby substantially constant starting and running torque is required through a revolution of the cam. The mill operates in wind conditions at which some conventional mills will not oper- ate. Some pumping occurs at winds of such low velocity which in some areas renders conventional mills inoperative or not practical.
