Engine House To Daubuz Shaft On South Wheal Frances Sett At Sw 674 390

CARN BREA TRESKILLARD SW 63 NE 8/172 Engine house to Daubuz shaft on South Wheal Frances sett at SW 674 390

GV II Pumping and winding engine house to former tin mine, now derelict. 1879-81, for South Frances Mine. Uncoursed granite rubble with quoins, bob wall of large dressed granite blocks, window arches of brick; now roofless. Rectangular plan on east-west axis, with bob wall to west, loadings for pumping and winding gear in front of this, remains of boiler house attached to south side, and chimney attached at north-east corner. Three stages, with mostly round-headed openings, including driver's window in bob wall, damaged cylinder door in rear wall (which is thicker than bob wall), a pair of small blocked windows above this and a larger window in the gable, a square-headed doorway to the former boiler house on the south side, round-headed windows on 2 levels to the right of this and a small blocked window to the right of the upper of these. Tapered cylindrical chimney stack of unusually large diameter (4 metres at the base), now terminating at gable level. Very prominent double loadings extending approx.10 metres in front of bob wall, one on the main axis for the flywheel and flat-rod connections to the pump, and a longer one parallel to it on the north side of the flywheel recess, for the winding drum. Remains of boiler house very fragmentary. History: the shaft, approx 60 metres to the west, was sunk at the request of the mineral lords in a period of expansion when mining here reached the Great Flat Lode, and named after J.C.Daubuz, a principal shareholder; the building contained a 30-inch engine, and its application to both pumping and winding was unusual.
