The tjasker is a small type of windmill used solely for drainage purposes. It is distinctive for its simple construction, featuring only a single inclined shaft that carries the sails on one end and an Archimedes' screw on the other, in this way avoiding the need for any gearing. The tjasker is commonly known as a typical Frisian windmill though it is also found in other Dutch provinces and in north Germany.

Berkswell windmill is a four bladed tower mill constructed in 1826 on the site of a former post mill, in the village of Balsall Common, in the parish of Berkswell, in the Metropolitan Borough of Solihull, West Midlands. The windmill is built in brick with a wooden boat shaped cap, and is turned into the wind by an endless chain winding mechanism. It was historically used to grind flour and animal feeds, and in 1927 the milling wheels were adapted to run via a diesel engine, not reliant upon the variable nature of the wind. The mill was finally closed in 1948, after the last miller John Hammond died.
