Stock Windmill is a grade II* listed tower mill at Stock, Essex, which has been restored.
Stock Windmill was built circa 1816 joining an existing post mill. In 1845, a second post mill was moved to a site close by.[1] By 1862, the mill had four shuttered sails.[2] The two post mills were demolished c.1890, about which time the millstones were moved down a floor and the drive converted from underdrift to overdrift. A steam engine was added in 1902 and the mill was working by wind until 1930 and afterwards by an internal combustion engine[1] until c.1936. The mill was bought by Essex County Council in 1945 and although preserved, by 1977 it was without the fantail and associated supporting timbers, and down to only one pair of sails. Major repairs were started in 1991 by Vincent Pargeter. A grant from English Heritage part-funded the work. The Friends of Stock Mill were formed in 1993 on completion of the restoration.[3]
The mill is a five-storey tower mill with four single Patent sails It has a boat-shaped cap winded by a six-bladed fantail. The tower is 20feet internal diameter at ground level and 12feet internal diameter at curb level. The walls are 22inches thick to first floor level and 18inches thick above that. The tower is 40feet high overall and the mill is 52feet to the top of the cap.[4]
As built, the mill had a stage at first-floor level, four common sails and was winded by hand.[1] It originally drove two pairs of overdrift millstones.[4]
The cast-iron windshaft was probably not made for the mill originally. It carries a 9feet diameter composite brake wheel with 81 cogs which has been converted from clasp arm construction. This drives a cast-iron wallower with 25 teeth. The cast-iron upright shaft is 5inches diameter and in three parts, with dog clutches at the fourth and fifth floor. The cast-iron great spur wheel is 5feet diameter with 76 cogs. It drove three pairs of underdrift millstones of 5feet, 4feet and 4feet diameter.[4]
