Cornish engine
From Wikipedia, the free encyclopedia
A Cornish engine is a high-pressure steam engine developed in Cornwall, United Kingdom, for pumping water from a tin mine. The engines were also used for winching workers and materials into and out of the mine. A Cornish engine pumps by a falling weight that is lifted by the engine. Few Cornish engines remain in their original locations, the majority having been scrapped when their related industrial concern closed.
The Kew Bridge Steam Museum in London, England has the largest collection of Cornish engines in the world. Two also survive in the town of Pool, Cornwall.
