Description

Bragg's Mill is a post mill with a single storey roundhouse. It has four patent sails carried on a wooden windshaft with a cast iron poll end. Two sails are double shuttered and two are single shuttered. Two pairs of millstones are driven, arranged Head and Tail. The mill is winded by tailpole. The mill is 34 ft (10.36 m) high to the roof.

 

Trestle and roundhouse

 

Before the recent restoration, the lower crosstree had been clamped at a quarterbar joint. The crosstrees stand within 3 ft 4 in (1.02 m) of ground level. The brick piers that the crosstrees rest on had been tarred, and the crosstrees themselve painted white, evidence that the mill was built as an open trestle mill. Both crosstrees are of oak, the upper being 24 ft (7.32 m) long and 13 by 12 in (330 by 305 mm) in section, whilst the lower crosstree is 12 by 111⁄2 in (305 by 292 mm) at the ends, thickening to 13 1⁄2 in (343 mm) at the centre. The post is 17 ft 6 in (5.33 m) long, and 27 in (686 mm) square at its base,

 

Body

 

The body of the mill measures 19 ft 10 in by 11 ft (6.05 by 3.35 m) in plan. At some point, the body of the mill had been extended at the back to provide room for a bolter. It was originally only 16 ft 6 in (5.03 m) long. The crown tree is 20 in (508 mm) square at the ends, thickening to 20 by 23 in (508 by 584 mm) at the centre. The side girts are 6 by 17 in (152 by 432 mm) by in section.

 

Sails and windshaft

 

The windshaft is of wood with a cast iron poll end, probably fitted at the same time that the Patent sails were added. The mill would originally have been built with common sails.

 

Machinery

 

The clasp arm wooden head wheel was converted from Compass arm construction, it is 7 ft 4 in (2.24 m) diameter. The wooden tail wheel has also been similarly converted, it is 6 ft 4 in (1.93 m) diameter. The mill was originally built with a single pair of millstones, the second pair probably being added when the mill was extended at the rear.
