Thomas Newcomen (1663-1729) was an ironmonger in Dartmouth, Devon, who spent ten years trying to develop a cheaper and more efficient way of pumping water out of Cornish tin mines than the use of horses. His first effective steam-driven pump was produced in partnership with another Devon man, Thomas Savery (1650-1715) around 1704. His first working engine was installed at Dudley Castle, Staffordshire in 1712.
Newcomen.s breakthrough was to introduce a squirt of cold water into a steam-filled chamber, thus creating a vacuum in the cylinder. This pulled the piston up and primed it to receive another injection of steam for the down stroke. Newcomen engines were not very efficient users of heat, but pumps based on his technology …
