1698 Thomas Savery, a Devon man, was the first to combine the force of steam and the pressure of the atmosphere. He was granted a patent in 1698 for "Raising water by the impellent force of fire". Savery's "engine" comprised a boiler and a receiver. Steam from the boiler filled the receiver. Cold water poured over the receiver condensed the steam causing a vacuum. Atmospheric pressure forced water up a suction pipe connected to the receiver, which became full of water. Steam from the boiler at pressure blew the water out of the receiver up a delivery pipe and also refilled the receiver with steam. The cycle was then repeated. Valves were fitted in pipes to control the steam and to prevent the water, which was being raised, from going the wrong way. In time the boiler became empty. To refill it with water meant drawing the fire and relieving the boiler of its pressure.
