In prior art, windmills had a simple tail vane which kept the wheel pointed directly at the wind, a simple design still in use in decorative garden windmills. Wheeler developed a mechanism that pointed the wheel into the wind at low to moderate wind speeds, but turned the wheel to point obliquely to the wind at high speeds.

In this nation more than others, "windmill" is often used to refer to what are properly termed windpumps bringing up water for agriculture. This is at least partly due to usage by windpump builders Eclipse Windmill Company (1873) and Aermotor Windmill Company (1888, the sole surviving US "windmill" manufacturer [ 1 ] ).
The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site.

Brent Pelham Mill was built in 1826 by William Halden, [1] who was at Meesden windmill in 1827. It was working until at least 1890 and was disused by 1898. At some point the mill was stripped of machinery and a water tank was built on the smock tower. The mill survives in this form today, clad in corrugated iron. [4]
