The Second Industrial Revolution Introduction
The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid standardization and industrialization from the late 19th century into the early 20th century. The First Industrial Revolution, which ended in the middle of 19th century, was punctuated by a slowdown in important inventions before the Second Industrial Revolution in 1870. Though a number of its events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914(the beginning of World War I)
Industry and technology:
A synergy between iron and steel, railroads and coal developed at the beginning of the Second Industrial Revolution. Railroads allowed cheap transportation of materials and products, which in turn led to cheap rails to build more roads. Railroads also benefited from cheap coal for their steam locomotives. This synergy led to the laying of 75,000 miles of track in the U.S. in the 1880s, the largest amount anywhere in world history.
Iron:
The hot blast technique, in which the hot flue gas from a blast furnace is used to preheat combustion air blown into a blast furnace, was invented and patented by James Beaumont Neilson in 1828 at Wilson town Ironworks in Scotland. Hot blast was the single most important advance in fuel efficiency of the blast furnace as it greatly reduced the fuel consumption for making pig iron, and was one of the most important technologies developed during the Industrial Revolution. Falling costs for producing wrought iron coincided with the emergence of the railway in the 1830s. The early technique of hot blast used iron for the regenerative heating medium. Iron caused problems with expansion and contraction, which stressed the iron and caused failure. Edward Alfred Cowper developed the Cowper stove in 1857. This stove used firebrick as a storage medium, solving the expansion and cracking problem. The Cowper stove was also capable of producing high heat, which resulted in very high throughput of blast furnaces. The Cowper stove is still used in today's blast furnaces.
STEEL:
The next great advance in steel making was the Siemens–Martin process. Sir Charles William Siemens developed his regenerative furnace in the 1850s, for which he claimed in 1857 to able to recover enough heat to save 70–80% of the fuel. The furnace operated at a high temperature by using regenerative preheating of fuel and air for combustion. Through this method, an open hearth furnace can reach temperatures high enough to melt steel, but Siemens did not initially use it in that manner. French engineer Pierre-Émile Martin was the first to take out a license for the Siemens furnace and apply it to the production of steel in 1865. The Siemens–Martin process complemented rather than replaced the Bessemer process. Its main advantages were that it did not expose the steel to excessive nitrogen (which would cause the steel to become brittle), it was easier to control, and that it permitted the Melting and refining of large amounts of scrap steel, lowering steel production costs and recycling an otherwise troublesome waste material. It became the leading steel making process by the early 20th century. The availability of cheap steel allowed building larger bridges, railroads, skyscrapers, and ships. Other important steel products—also made using the open hearth process—were steel cable, steel rod and sheet steel which enabled large, high-pressure boilers and high-tensile strength steel for machinery which enabled much more powerful engines, gears and axles than were previously possible. With large amounts of steel it became possible to build much more powerful guns and carriages, tanks, armored fighting vehicles and naval ships.
RAIL:
The increase in steel production from the 1860s meant that railroads could finally be made from steel at a competitive cost. Being a much more durable material, steel steadily replaced iron as the standard for railway rail, and due to its greater strength, longer lengths of rails could now be rolled. Wrought iron was soft and contained flaws caused by included dross. Iron rails could also not support heavy locomotives and was damaged by hammer blow. The first to make durable rails of steel rather than wrought iron was Robert Forester Mushet at the Darkhill Ironworks, Gloucestershire in 1857. The first of his steel rails was sent to Derby Midland railway station. They were laid at part of the station approach where the iron rails had to be renewed at least every six months, and occasionally every three. Six years later, in 1863, the rail seemed as perfect as ever, although some 700 trains had passed over it daily. This provided the basis for the accelerated construction of rail transportation throughout the world in the late nineteenth century. Steel rails lasted over ten times longer than did iron, and with the falling cost of steel, heavier weight rails were used. This allowed the use of more powerful locomotives, which could pull longer trains, and longer rail cars, all of which greatly increased the productivity of railroads. Rail became the dominant form of transport infrastructure throughout the industrialized world, producing a steady decrease in the cost of shipping seen for the rest of the century.
ELECTRIFICATION:
The theoretical and practical basis for the harnessing of electric power was laid by the scientist and experimentalist Michael Faraday. In 1881, Sir Joseph Swan, inventor of the first feasible incandescent light bulb, supplied about 1,200 Swan incandescent lamps to the Savoy Theatre in the City of Westminster, London, which was the first theatre, and the first public building in the world, to be lit entirely by electricity. Swan's light bulb had already been used in 1879 to light Mosley Street, in Newcastle upon Tyne, the first electrical street lighting installation in the world. This set the stage for the electrification of industry and the home. The first large scale central distribution supply plant was opened at Holborn Viaduct in London in 1882 and later at Pear Street Station in New York City.
PAPPER MAKING:
It was in the 1840s, that Charles Fenerty in Nova Scotia and Friedrich Gottlob Keller in Saxony both invented a successful machine which extracted the fibres from wood (as with rags) and from it, made paper. This started a new era for paper making, [38] and, together with the invention of the fountain pen and the mass-produced pencil of the same period, and in conjunction with the advent of the steam driven rotary printing press, wood based paper caused a major transformation of the 19th century economy and society in industrialized countries. With the introduction of cheaper paper, schoolbooks, fiction, non-fiction, and newspapers became gradually available by 1900. Cheap wood based paper also allowed keeping personal diaries or writing letters and so, by 1850, the clerk, or writer, ceased to be a high-status job. By the 1880s chemical processes for paper manufacture were in use, becoming dominant by 1900.
PETROLIUM:
The petroleum industry, both production and refining, began in 1848 with the first oil works in Scotland. The chemist James Young set up a tiny business refining the crude oil in 1848. Young found that by slow distillation he could obtain a number of useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax. In 1850 Young built the first truly commercial oil-works and oil refinery in the world at Bathgate, using oil extracted from locally mined torbanite, shale, and bituminous coal to manufacture naphtha and lubricating oils; paraffin for fuel use and solid paraffin were not sold till 1856.
RUBBER:
The vulcanization of rubber, by American Charles Goodyear and Englishman Thomas Hancock in the 1840s paved the way for a growing rubber industry, especially the manufacture of rubber tyres John Boyd Dunlop developed the first practical pneumatic tyre in 1887 in South Belfast. Willie Hume demonstrated the supremacy of Dunlop's newly invented pneumatic tyres in 1889, winning the tyre's first ever races in Ireland and then England. Dunlop's development of the pneumatic tyre arrived at a crucial time in the development of road transport and commercial production began in late 1890.
BICYCLES:
The modern bicycle was designed by the English engineer Harry John Lawson in 1876, although it was John Kemp Starley who produced the first commercially successful safety bicycle a few years later. Its popularity soon grew, causing the bike boom of the 1890s. Road networks improved greatly in the period, using the Macadam method pioneered by Scottish engineer John Loudon McAdam, and hard surfaced roads were built around the time of the bicycle craze of the 1890s. Modern tarmac was patented by British civil engineer Edgar Purnell Hooley in 1901.
AUTOMOBILE:
German inventor Karl Benz patented the world's first automobile in 1886. It featured wire wheels (unlike carriages' wooden ones) with a four-stroke engine of his own design between the rear wheels, with a very advanced coil ignition and evaporative cooling rather than a radiator. Power was transmitted by means of two roller chains to the rear axle. It was the first automobile entirely designed as such to generate its own power, not simply a motorized-stage coach or horse carriage.
