Around 1710 NewCommon invented Atmospheric Engine using steam for powering Water Pump to take out water from Coal Mines of England.
He then used a lever to transfer the force to the pump shaft that went down the mine. It was the first practical engine to use a piston in a cylinder.. Thomas Newcomen invented the atmospheric steam engine. Michigan State University's College of Engineering explains that the system is constructed so that the beam is heavier on the main pump side with gravity pulling down that side of the beam.
