Around 1710 English ironmonger, Baptist lay preacher, and inventor Thomas Newcomen developed the atmospheric reciprocating engine, which unlike the steam pump (The Miner's Friend) developed by Thomas Savery in 1698, employed a piston in a cylinder, the vacuum pulling the piston down to the bottom of the cylinder when water was injected into it, ...
The atmospheric engine invented by Thomas Newcomen in 1712, often referred to simply as a Newcomen engine, was the first practical device to harness the power of steam to produce mechanical work.Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines.Hundreds were constructed through the 18th century. James Watt 's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency.ewcomen's engine was only replaced when James Watt improved it in 1769 to avoid this problem (Watt had been asked to repair a model of a Newcomen engine by Glasgow University.
