Windmill water pumps were common on the prairie before rural electrification.  Today a working windmill is a rare item; in fact so are non working ones like the one pictured here.  It's a relatively simple machine.  Wind turns a shaft which is connected to a simple gear box.  The shaft coming out of the gear box has an offset arm which is connected to a drop down shaft whioch in turn is connected to the pump handle.  Note: the drop down shaft is not connected to the pump handle on this pump; it is missing.
