This mill is fitted with Patent sails which work by opening and closing the slats on the sails in a similar fashion to a Venetian blind.
This was a major step forward in that the adjustments can be made whilst the sails are still turning & the miller did not require an assistant to apply the brake whilst sails are adjusted.
The Tower mill showing the brickwork
The body of the model is solid beech, the brick course horizontals were turned on an old Holbrook model B No.8 screwcutting lathe in order to keep precision, each brick measures approx 1/8" X 1/16" in 1/72" scale
This Tower mill dominates the skyline but is in a low lying area and is built high to catch the wind.
By operating a long chain - which hangs down to the gallery- the miller can adjust the speed at which the sails turn via a system of gearing & levers which pass through the cap and onto the mechanisms on the sails. This opens & closes the slats according to the wind conditions.
The mill also features a fantail mechanism which is an automatic method of keeping the sails turned into the wind by revolving the entire white painted 'cap' via a gearing on the curb on the top of the tower.
The boardwalk staging permits the miller to walk around to access the chain and also aids maintenance of the sails.
