I am interested in the “Governor” it is a device which was common on some steam engines
Controls the speed of the engine as the engine speeds up the balls are thrown out by the centrifugal force and as it slows they drop back in. This movement is used to automatically adjust the throttle, so that the engine is kept running at a constant speed.
Joseph Evans Reliable Steam Pump
Reliable horizontal 4x2x4, No.26900, 1929
Size: 4" steam cylinder, 2" pumping cylinder with 4" stroke and 24" diameter flywheel, double acting.
Woodall Duckham Ltd, purchased this pump in 1929 for the new Bedwas coke works, Trethomas Monmouthshire and used it for internal transfers and the loading of crude tar into road and rail vehicles. From 1939 when Caerphilly Tar Plant opened, Bedwas tar was sent to Caerphilly for distilling.
Bedwas coke works closed on 23 December 1986 and this pump was purchased for £10 from the demolition contractors in March 1987. Upon stripping it was found to be well worn, and the valve rod in the steam chest had been eroded to half its original thickness, due to the action of wet steam impingement. A replacement rod has been manufactured and many other parts have been replaced with original spares obtained from the stores at Caerphilly upon closure.
The pump is complete, in working order, and runs well on compressed air. It is the smallest of the" Reliable" steam pumps manufactured by Evans being of 4" stroke, other pumps in the series were manufactured with either 6", 9" or 12" stroke. This particular pump is not fitted with a reversible eccentric.
This pump is presently on display at the Museum of Power, Langford, Maldon, Essex and regularly runs on air.
