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 Newcomen Engine combined Savery's separation of the boiler and steam cylinder with Papin's steam-driven piston. This content is not compatible on this device. While Savery sought to replace conventional horse-driven pumps with his engine, Newcomen sought to use a steam-driven pump to do the work of horses. Newcomen's engine was similar to Savery's. It included a steam-filled chamber that was cooled by a quick injection of cold water to create a vacuum-inducing change in atmospheric pressure.
