Glascoed Mill

Glascoed Mill is a 18th-century building, constructed of limewashed rubble stone with a slate roof, hipped at the south end. It is a three-storey structure with a lower bay added at the north end, containing a door and window, and a former wheel pit at the south end enclosed within a timber weatherboarded structure now covered with a corrugated iron roof.

The mill comprises two bays, extending over ground, first (stone), and attic (hoist) floors. A stable door and a loading door provide access to the ground floor, while two light windows with segmental heads are present on the stone floor. Various iron tie bars with iron felloes serve as end restraints. A chimney is located at the north end, partially reduced in height. The main building extends back from the river, with a lower, two-storey stone structure featuring a door and window to the upper floor.

Immediately southwest of the mill is a water entry flume containing two sets of cog-operated paddles and sluices. The external waterwheel was apparently removed in 1923 and the area partially filled. Within the filled area is a vertical shaft containing a large horizontal iron turbine at a low level, alongside a spoked belt pulley at the top, connected by a belt that is turned by an idler at a 45-degree angle to engage the main horizontal mill drive. The turbine has a chainlink control mechanism engaged by an escapement rocker on a vertical shaft, geared to a horizontal shaft passing diagonally across at high level, linked to an auxiliary oil engine.

The ground floor is divided into two bays of unequal size; the larger northern bay is a workshop containing a continuous bench against the east wall, set over a horizontal layshaft. A small, portable belt-driven grindstone is also present. The narrower south bay, originally for the pit wheel, is divided off with a timber partition and has an irregular floor, six steps lower than the rest of the ground floor. This area contains two long vertical iron drive shafts used for belts to engage the new, 1923-installed elongated stone spindles. One shaft features a belt pulley with curved radial arms, supported by an original wooden axle tree, which has been re-used as a floor beam. A dog-leg staircase leads up to the stone floor, which contains two pairs of underdrift French stones in their original octagonal vats, complete with horses, hoppers, slippers, and quants with damsels. An ancillary horizontal drive, geared down 50% with bevel gear over the stones, likely drove the wire dressing machine, which remains in place in the north corner. A ladder provides access to the second floor, which houses the sack hoist pulley and drum, operated by extant chain and rope from the workshop floor via floor traps.

The lower extension building has a fireplace with an iron range in the gable wall of the main block, and a large spoked belt drive at the end of the main horizontal drive against the east wall. The belt reportedly drove the remaining ball and planets governor.
