The Steam Engine in the British Industrial Revolution

Another key innovation was that instead of using a straight piston rod (which could easily jam if bent slightly), a chain was used. Newcomen's steam engine pump was first used in a coal mine in Dudley in the Midlands in 1712. The machine could suck 5,000 gallons (22.7 K litres) every hour out of a 153-foot (46.6 metres) deep mine shaft.
