1. The compound steam engine. It gave birth to practical railways and more efficient applications of power to manufacturing industries. There were many other inventions too which were ancilliary to it especially in metallurgy, mechanical and structural engineering. One which is often overlooked is the tunnelling shield invented by Isambard Kingdom Brunel.
2. As the flying shuttle sped up weaving, the demand for cotton yarn increased. Many inventors set to work to improve the spinning wheel. James Hargreaves, a weaver who was also a carpenter, patented his spinning jenny in 1770. It enabled one worker to run eight spindles instead of one. About the same time Richard Arkwright developed his water frame, a machine for spinning with rollers operated by water power. In 1779 Samuel Crompton, a spinner, combined Hargreaves' jenny and Arkwright's roller frame into a spinning machine, called a mule. It produced thread of greater fineness and strength than the jenny or the roller frame. Since the roller frame and the mule were large and heavy, it became the practice to install them in mills, where they could be run by water power. They were tended by women and children.These improvements in spinning machinery called for further improvements in weaving. In 1785 Edmund Cartwright patented a power loom. In spite of the need for it, weaving machinery came into use very slowly. First, many improvements had to be made before the loom was satisfactory. Second, the hand weavers violently opposed its adoption because it threw many of them out of work. Those who got jobs in the factories were obliged to take the same pay as unskilled workers. Thus they rioted, smashed the machines, and tried to prevent their use. The power loom was only coming into wide operation in the cotton industry by 1813. It did not completely replace the hand loom in weaving cotton until 1850. It was not well adapted to the making of some woolens. As late as 1880 many hand looms were still in use for weaving woolen cloth.Many other machines contributed to the progress of the textile industry. In 1785 Thomas Bell of Glasgow invented cylinder printing of cotton goods. This was a great improvement on block printing. It made successive impressions of a design “join up” and did the work more rapidly and more cheaply. In 1793 the available supply of cotton was increased by Eli Whitney's invention of the cotton gin (see Whitney, Eli). In 1804 J.M. Jacquard, a Frenchman, perfected a loom on which patterns might be woven in fabrics by mechanical means. This loom was later adapted to the making of lace, which became available to everyone (see Lace).Watt's Steam Engine While textile machinery was developing, progress was being made in other directions. In 1763 James Watt, a Scottish mechanic, was asked to repair a model of a Newcomen steam engine. He saw how crude and inefficient it was and by a series of improvements made it a practical device for running machinery. Wheels turned by running water had been the chief source of power for the early factories. These were necessarily situated on swift-running streams. When the steam engine became efficient, it was possible to locate factories in more convenient places.The first users of steam engines were the coal and iron industries. They were destined to be basic industries in the new age of machinery. As early as 1720 many steam engines were in operation. In coal mines they pumped out the water which usually flooded the deep shafts. In the iron industry they pumped water to create the draft in blast furnaces. The iron industry benefited also from other early inventions of the 18th century. Iron was scarce and costly, and production was falling off because England's forests could not supply enough charcoal for smelting the ore. Ironmasters had long been experimenting with coal as a fuel for smelting. Finally the Darby family, after three generations of effort, succeeded with coal that had been transformed into coke. This created a new demand for coal and laid the foundation for the British coal industry. The next great steps were taken in the 1780s, when Henry Cort developed the processes of puddling and rolling. Puddling produced nearly pure malleable iron. Hand in hand with the adoption of the new inventions went the rapid development of the factory system of manufacture.
