The common sail is the simplest form of sail. In medieval mills, the sailcloth was wound in and out of a ladder-type arrangement of sails. Medieval sails could be constructed with or without outer sailbars. Post-medieval mill sails have a lattice framework over which the sailcloth is spread. There are various "reefs" for the different spread of ...
The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
The use of windmills became widespread across the Middle East and Central Asia, and later spread to China and India. [22] Vertical windmills were later used extensively in Northwestern Europe to grind flour beginning in the 1180s, and many examples still exist. [23] By 500 AD, windmills were used to pump seawater for salt-making in China and ...
The sails were removed c1925. The mills were worked by engine until 1937. [3] The mill retained its cap and fanstage in 1933 but had become derelict by 1949. The cap and top storey of the mill had been removed by the time the mill buildings were advertised for sale by auction in King's Lynn on 29 July 1980.
The mill was offered for sale in 1891, and in 1900 was bought by Reigate Golf Club, who leased the mill back to the church. In 1926, a sail broke. New sails were fitted in 1927 by a millwright from Crawley, and a dummy fantail fitted to the rear of the mill - a feature the mill never had during its working life! The sails blew off in 1943 and ...

[ 43 ] [ 9 ] [ 10 ] The sails covering the two pairs of wings, which are composed of four 10-meter-long canvas sheets [ 167 ] spaced 1.5 meters around the hub of the main shaft, [ 59 ] are supported by a frame of welded steel bars that extend over 25 meters in length.
The windmill remained property of the Van Bronckhorst family and later, by marriage, the Törring family until it was confiscated by the government in the French-Batavian period and publicly sold in 1805. The buyer was Van Gulpen who sold the mill on to miller Jacobus Jacobs who expanded the milling business with a farm.
There was no brakewheel and so sails were fixed accordingly to face to the East. In 1970, a grant was given by the Norfolk Windmills Trust to restore the paintwork of the windmill and in 1973 a further grant was given by the Trust for further renovation and maintenance work. In 1982 the windmill was once again up for sale and was sold for £ ...
