Model, scale 1:24, of the smock windmill at Cranbrook, Kent, as it appeared in the mid 19th century, sectioned

Sectioned model (Scale 1:24) of Smock windmill from Cranbrook, Kent, c.1840. The smock mill at Cranbrook was originally built in 1814. The smock mill is so called because of the appearance of its tapered wooden tower. The windshaft to which the sails are fixed is carried in a moveable wooden cap. Originally this was turned to face the wind by hand, using gearing that meshes with iron teeth bolted onto the curb around the cap. William Cubitt's patent sails of 1807 are fitted. These consist of moveable shutters that can be adjusted as the mill turns. The machinery comprises three pairs of stones, their separation controlled by centrifugal governors, a wire machine and a bolter (for dressing flour) and sack hoists.
