Goonvean China Clayworks - Cornish beam pumping engine 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 was a picture of the top chamber with the indoor end of the beam before the stairs became even softer and the roof was damaged by high winds. The beam was a replacement by Holman Bros of camborne in 1928. The engine ceased work in about 1955. Its removal was just in time, as the air pump and condenser had already fallen down the unstable shaft and part of the engine house followed not long after the engine's safe removal. The remainder of the house was then quickly demolished. There is now only one engine in situ 'in the clay' - that at Parkandillick.

This is a view of the bottom chamber with the driver's position and the cylinder behind on the right. The 'gearwork' is typical three arbor gearwork with a double plug rod and cataracts for pauses on the indoor and outdoor strokes. The engine has a single perpendicular pipe connecting the two ends of the cylinder.

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.

This is a close up of the middle chamber with the valve box to the right and the plug rods operating the valve gear to the left. Between are the rods and operating levers for the governor, steam and equilibrium valves. The device with the ratchet and bevel gears is the St Austell governor. This is a safety feature that closes the governor valve if the engine stroke length begins to increase. It is, however, defenceless in the face of a catastrophic failure - eg the main pump rod parting.

This is outside the front of the engine house over the shaft leading to the bottom of the claypit. On the right is the large timber main pump rod. To its left is a disconnected auxiliary pump. Then further left is the rotten wooden cistern holding the condenser (hidden) and the air pump that is worked off the beam. Above and behind the airpump is the boiler feed pump and then above and behind that is the 'plug door' into the lower chamber of the engine house. Some years later the condenser cistern and its contents slipped down the shaft. Following removal of the engine, part of the house went the same way (the people who removed this engine were dicing with death) and the remainder was demolished immediately after.
