The Stephensons incorporated elements into their engines that were used in succeeding generations of steam engines. The Rocket won the £500 prize with its average speed of 13 miles per hour (without pulling a load, the Rocket attained speeds up to 29 miles per hour), beating out Braithwaite and Erickson's Novelty and Timothy Hackworth's Sans Pareil. The Rocket won the competition at the Rainhill Trials held to settle the question of whether it was best to move wagons along rails by fixed steam engines using a pulley system or by using locomotive steam engines. In 1829, the Stephensons built the famous locomotive Rocket, which used a multi-tube boiler, a practice that continued in successive generations of steam engines. Stephenson built his "travelling engine" in 1814, which was used to haul coal at the Killingworth mine. George Stephenson and his son, Robert, built the first practical steam locomotive. Trevithick wrote on February 21, 1804, after the trial of his High Pressure Tram-Engine, that he "carry'd ten tons of Iron, five wagons, and 70 Men.above 9 miles.in 4 hours and 5 Mints." Though a ponderous-sounding journey, it was the first step toward an invention that would utterly change man's relationship to time and space. In 1802, Richard Trevithick patented a "high pressure engine" and created the first steam-powered locomotive engine on rails. To achieve motive steam power would, for the first time in history, allow man to travel on land at a speed faster than that of the domesticated horse. In partnership with manufacturer Matthew Boulton, Watt's improvements and inventions powered the industrial revolution.įollowing Watt's improvements, many inventors attempted to adapt the steam engine to modes of transport on both land and water. His patents also included such ancillary devices as pressure gauges, throttle valves, and steam regulators. In the late 18 th century, James Watt, the man who would eventually be called the father of the steam engine, greatly improved the efficiency of the stationary engine when he patented a "double acting" engine that used high pressure steam on both sides of the piston to double the output. Though it was not very efficient, hundreds of these engines were used for pumping water from British coal mines and flooded areas. The Newcomen atmospheric engine used steam to power a pump. In 1712, Thomas Newcomen and his assistant John Cally unveiled the first commercially viable steam engine. The cooling water drains out and the cycle repeats indefinitely. When the piston reaches the top of the cylinder, a jet of water is injected into the piston cylinder causing the steam to condense, sucking the piston back down. The piston rod is attached to a crossbeam and as the piston rises, the weight of a pump rod hung on the opposite end of the beam pulls downward. Water is boiled to create steam that pushes upward on a piston in a cylinder.
