The Disaster of Innovation Eli Whitney patented his cotton engine, or “gin,” in 1794. A mechanical device to separate cotton fibers from cotton seed, it dramatically lowered the cost of producing cotton fiber. Formerly, workers (usually slaves) had separated the seeds from the lint by hand, painstaking work that required hours of work to produce a pound of lint.

- Thomas Newcomen was a prominent British engineer, best known for inventing the atmospheric steam engine, which was the the world’s oldest known steam engine for pumping water. The Newcomen engine largely influenced later designs such as James Watt’s engine.

Cyrus McCormick Cyrus McCormick. Inventor of the Mechanical Reaper. Not long after Eli Whitney invented the Cotton Gin, Cyrus McCormick invented another significant agricultural invention that revolutionized farming: the mechanical reaper. Prior to this invention, reaping was a painstaking process (done by hand with a scythe) that limited a farm's harvest.

- The bands invented at that time were not vulcanised and would soften on hot days or harden on cold ones. The American Charles Goodyear invented vulcanisation in the 1840s, but Hancock was quick to exploit the technique (and claimed the invention!): vulcanisation eliminated the temperature dependence of rubber behaviour.

Famous Devonians In 1712 Newcomen invented the world's first successful atmospheric steam engine. The engine pumped water using a vacuum created by condensed steam. It became an important method of draining water from deep mines and was therefore a vital component in the Industrial Revolution in Britain.

What did John D. Dunlop invent? Since the implementation of pneumatic tires, bicycles have become extremely popular in Europe, where they provide an alternative to automobiles. John Dunlop himself did not take a prominent role in the tire company he helped to found, and sold his shares after several years.

- Of these, none had so great an impact on the invention of the tire than John Dunlop and Charles Goodyear. Charles Goodyear and the Invention of Vulcanized Rubber. None of it would have been possible without Charles Goodyear, who in 1844 -- more than 50 years before the first rubber tires would appear on cars -- patented a process known as vulcanization.

- Solid rubber tires were preferred over pneumatic tires because of their durability, so pneumatic tires fell into disuse. The popularity of bicycles in the late 1800s revived the idea of the pneumatic tire, and in 1888 a Belfast veterinary surgeon named John Boyd Dunlop obtained a patent for a pneumatic bicycle tire.

- The cotton gin was a revolutionary device invented by Eli Whitney in 1793. It efficiently separated seeds from cotton fiber, allowing users to produce up to 50 pounds of lint a day. The invention of the cotton gin had profound implications: it allowed cotton to become the dominant cash crop in the South.

- Newcomen Atmospheric Engine. Thomas Newcomen (1663-1729), a blacksmith, experimented for 10 years to develop the first truly successful steam engine to drive a pump to remove water from mines. His ability to sell the engine was hampered by Savery's broad patent. He was forced to establish a firm with Savery, despite the improved performance of his engine, the significant mechanical differences, the elimination of the need for steam pressure, and the use of vacuum in a very different manner. A schematic of a Newcomen engine is shown in Figure 1.
