A fantail is a small windmill mounted at right angles to the sails, at the rear of the windmill, and which turns the cap automatically to bring it into the wind. The fantail was patented in 1745 by Edmund Lee, a blacksmith working at Brockmill Forge near Wigan , England, and was perfected on mills around Leeds and Hull towards the end of the ...
Billingford Windmill is a five-storey tower mill with a boat-shaped cap winded by a fantail. The tower is 36 feet (10.97 m) high to curb level. It has four double Patent sails carried on a cast-iron windshaft. The brake wheel carries a tablet inscribed "W SKINNER 1860". The upright shaft is of cast iron, and is 4 + 1 ⁄ 2 inches (114 ...
In the event of change in wind direction the fantail would rotate thus transmitting its mechanical power through a gearbox (and via a gear-rim-to-pinion mesh) to the tower of the windmill. The effect of the aforementioned transmission was the rotation of the nacelle towards the direction of the wind, where the fantail would not face the wind ...
Later an endless chain was used which drove the cap through gearing. In 1745 an English engineer, Edmund Lee, invented the windmill fantail – a little windmill mounted at right angles to the sails, at the rear of the mill, and which turned the cap automatically to bring it into the wind. [15]
Stansted Mountfitchet Windmill is a five-storey tower mill with a domed cap winded by an eight bladed fantail. [4] The tower is 21 feet 6 inches (6.55 m) diameter at base, and 10 feet (3.05 m) diameter at curb level. The brickwork is only 27 inches (690 mm) thick at ground level, and generally only about 18 inches (460 mm) at higher levels ...

The necessary yawing torque was created by means of animal power, human power or even wind power (implementation of an auxiliary rotor known as fantail). Vertical-axis wind turbines (VAWTs) do not need a yaw system since their vertical rotors can face the wind from any direction and only their self rotation gives the blades a clear direction of ...
