Grenville Stamps New Engine
House
The engine house which sat at the head of the New Stamps dressing floors
is set on the southern slopes of the valley, and is an important landscape
feature. The engine house with its 30" engine and the associated dressing
floors downslope were constructed in 1891 to provide new dressing
facilities for the Grenville United Mines and was connected to the old
East Grenville production shafts by an extensive tramway.
The engine, bought from West Condurrow for £300, had an auxiliary beam operated
by the left-hand stamps flywheel to pump water to the stamps grates.
Grenville stamps were increased to 136 heads in
1892 and a 20-inch engine was acquired to pump water to the floors;
presumably the auxiliary beam was dispensed with at this time.
