Industrial Revolution


One of the earliest factories was John Lombe's water-powered silk mill at Derby, operational by 1721. By 1746, an integrated brass mill was working at Warmley near Bristol. Raw material went in at one end, was smelted into brass and was turned into pans, pins, wire, and other goods. Housing was provided for workers on site. Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, who employed the factory system.
The factory system began widespread use somewhat later when cotton spinning was mechanized.

Richard Arkwright is the person credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England. The factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a worker's cottage. Working hours were as long as they had been for the farmer, that is, from dawn to dusk, six days per week. Overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities. Arkwright's factory was the first successful cotton spinning factory in the world; it showed unequivocally the way ahead for industry and was widely copied.
Between 1820 and 1850 mechanized factories supplanted traditional artisan shops as the predominant form of manufacturing institution, because the larger-scale factories enjoyed a significant technological advantage over the small artisan shops. The earliest factories (using the factory system) developed in the cotton textile industry. Later generations of factories included mechanized shoe production and manufacturing of machinery, including machine tools. Factories that supplied the railroad industry included rolling mills, foundries and locomotive works. Agricultural-equipment factories produced cast-steel plows and reapers. Bicycles were mass-produced beginning in the 1880s.
The Nasmyth, Gaskell and Company's Bridgewater Foundry, which began operation in 1836, was one of the earliest factories to use modern materials handling such as cranes and rail tracks through the buildings for handling heavy items.[21]
Large scale electrification of factories began around 1900 after the development of the AC motor which was able to run at constant speed depending on the number of poles and the current electrical frequency.[22] At first larger motors were added to line shafts, but as soon as small horsepower motors became widely available, factories switched to unit drive. Eliminating line shafts freed factories of layout constraints and allowed factory layout to be more efficient. Electrification enabled sequential automation using relay logic.

Henry Ford further revolutionized the factory concept in the early 20th century, with the innovation of the mass production. Highly specialized laborers situated alongside a series of rolling ramps would build up a product such as (in Ford's case) an automobile. This concept dramatically decreased production costs for virtually all manufactured goods and brought about the age of consumerism.[verification needed]
In the mid- to late 20th century, industrialized countries introduced next-generation factories with two improvements:
  1. Advanced statistical methods of quality control, pioneered by the American mathematician William Edwards Deming, whom his home country initially ignored. Quality control turned Japanese factories into world leaders in cost-effectiveness and production quality.
  2. Industrial robots on the factory floor, introduced in the late 1970s. These computer-controlled welding arms and grippers could perform simple tasks such as attaching a car door quickly and flawlessly 24 hours a day. This too cut costs and improved speed.
Some speculation[citation needed] as to the future of the factory includes scenarios with rapid prototyping, nanotechnology, and orbital zero-gravity facilities.
