THE COTTON GIN A cotton gin is a machine that quickly and easily separates the cotton fibers from the seeds, a job formerly performed by hand. The fibers are processed into cotton goods, and the seeds may be used to grow more cotton, to produce cottonseed oil, or, if they are badly damaged, are disposed of. The gin uses a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously remove the loose cotton lint to prevent jams. The modern version of the cotton gin was created by the American inventor Eli Whitney in 1793 to mechanize the cleaning of cotton. The invention was granted a patent on March 14, 1794. There is slight controversy over whether the idea of the cotton gin and its constituent elements…show more content…
Incorporating technologies discovered by Savery and Denis Papin, the atmospheric engine, invented by Thomas Newcomen, paved the way for the Industrial Revolution. Newcomen's engine was relatively inefficient, and in most cases was only used for pumping water. It worked by using the vacuum from condensing steam in a cylinder and was mainly employed for draining mine workings at depths hitherto impossible, but also for providing a reusable water supply for driving waterwheels at factories sited away from a suitable…show more content…
Watt's engine used 75% less coal than Newcomen's, and was much cheaper to run. Watt proceeded to develop his engine further, modifying it to provide a rotary motion suitable for driving factory machinery. This enabled factories to be sited away from rivers, and further accelerated the pace of the Industrial Revolution. Newcomen's and Watt's early engines were "atmospheric", meaning that they were powered by the vacuum generated by condensing steam instead of the pressure of expanding steam. Cylinders had to be large, as the only usable force acting on them was atmospheric pressure. Steam was only used to compensate for the atmosphere allowing the piston to move back to its starting position. Around 1800, Richard Trevithick introduced engines using high-pressure steam. These were much more powerful than previous engines and could be made small enough for transport applications. Thereafter, technological developments and improvements in manufacturing techniques (partly brought about by the adoption of the steam engine as a power source) resulted in the design of more efficient engines that could be smaller, faster, or more powerful, depending on the intended
