In the year 1722, Henry S. Parmalee invented the fire extinguisher. The equipment increased the efficiency of firefighting than other tactics that were being used before its invention (Bellies, n.p). In the year 1724, Gabriel Fahrenheit invented the first mercury thermometer that made it possible to measure very slight temperature changes. In 1733, John Kay invented the flying shuttle that sped up work at the textile industries by allowing a single weaver to weave many wide fabrics as well as allowing for the automatic machine looms. In 1969, one of the most important inventions in the 18th century was made. James Watt invented an improved steam engine. Notably, Thomas Newcomen had made the first steam engine in 1712, but it had not performed well. Watt's improvement on the engine was commendable, making the steam engine the primary source of power up to the 20th century (Wiser 190).
In 1774, Georges Louis Lesage patented the electric telegraph ( Bellies, n.p). The invention was the first to permit almost instant communication across continents and oceans. It, therefore, was of significant economic and social impact. In 1775, Jacques Perrier invented a steamship, which was the first kind of ship that was not dependent on wind patterns (Bellies, n.p). The steamship enabled better navigation and the opening of new trade routes. In addition, the steamship facilitated the exploration of the world even wider than before. In 1794, Eli Whitney patented the cotton gin, which was one of the most critical inventions in the textile industry since it enhanced the separation of cotton fibres from their seeds in a speed incomparable to the manual methods used before. In the same year, Philip Vaughan invented ball bearings which were quite important in the manufacturing of machines. In 1796, a significant milestone was made in the field of medicine, as Edward Jenner discovered the smallpox vaccination (Bellies, n.p). The discovery improved man's quality of life and reduced the deaths caused by the illness. In 1799, Alessandro Volta invented the battery which served as the main source of electricity before the electric generator could later be developed in the late 19th century.
