Sump
shaft is the deepest on the mine and is sometimes called Engine shaft.
Around it lies a complex of buildings that include a winding engine,pump
engine, capstan engine and explosives magazine.
The winding engine lies upslope of the shaft and in addition to winding at Sumps this engine provided power by flat rods to Pearce's shaft higher up the hill .A 22 inch horizontal engine was housed in this building (some sources state a 16/30"). The was engine designed by William West. and was probably installed in 1844 (ref CAU) . Horizontal engines did not require a substantial bob wall and the structure was therefore lighter than a traditional Cornish Engine house. |

This now has two partial walls and a partial height chimney still standing. On the left side are the loadings for the winding drum and flat rods crank. On the opposite wall low walls mark the position of a long narrow boiler house with the chimney on its uphill side. . |
 The Canal, Railways and Mines by Michael Messenger Click on the photograph for a wider view. The picture clearly shows that the sump shaft winding engine house was not a traditional Cornish beam engine structure.This was because it housed a 22" twin cylinder horizontal engine that did not require a beam and its supporting heavy bob wall. In addition to winding at Sump shaft this engine provided power by flat rods to Pearce's shaft higher up the hill .The boiler house is sited on this side and its lean to roof can be seen, the loadings and flywheel are on the opposite hidden face.The headgear of Pearce's shaft lies to the left of the view and the chimney on the right was believed to have served a steam capstan. |
