50" Cornish beam engine of 1863 by Harvey & Co of Hayle. Installed 4th hand in 1910. Dismantled by Century millwrights in September 2008 and placed in store. It is hoped that it may be re-erected in a proposed project in Hayle. This is the middle chamber showing the top of the steam cylinder with the false cover and the metallic packing for the piston rod. Beyond that is the top nozzle box with the governor, steam inlet and equilibrium valves. Above, one can see parts of the parallel motion with the plug rod descending beyond the top nozzles to operate the valve gear. This was in the days when the staircase was just strong enough to allow access to the higher levels. On a later visit I was restricted to the lower chamber.
