Steam Engines

The Steam Engine

The steam engine provided a landmark in the industrial development of Europe. The first modern steam engine was built by an engineer, Thomas Newcomen, in 1705 to improve the pumping equipment used to eliminate seepage in tin and copper mines. Newcomen's idea was to put a vertical piston and cylinder at the end of a pump handle. He put steam in the cylinder and then condensed it with a spray of cold water; the vacuum created allowed atmospheric pressure to push the piston down. In 1763 James watt, an instrument-maker for Glasgow University, began to make improvements on Newcomen's engine. He made it a reciprocating engine, thus changing it from an atmospheric to a true "steam engine." He also added a crank and flywheel to provide rotary motion.

In 1774 the industrialist Michael Boulton took Watt into partnership, and their firm produced nearly five hundred engines before Watt's patent expired in 1800. Water power continued in use, but the factory was now liberated from the streamside. A Watt engine drove Robert Fulton's experimental steam vessel Clermont up the Hudson in 1807.

Railroads

The coming of the railroads greatly facilitated the industrialization of Europe. At mid.eighteenth century the plate or rail track had been in common use for moving coal from the pithead to the colliery or furnace. After 1800 flat tracks were in use outside London, Sheffield, and Munich. With the expansion of commerce, facilities for the movement of goods from the factory to the ports or cities came into pressing demand. In 1801 Richard Trevithick had an engine pulling trucks around the mine where he worked in Cornwall. By 1830 a railway was opened from Liverpool to Manchester; and on this line George Stephenson's ''Rocket'' pulled a train of cars at fourteen miles an hour.
