The Power Loom: How Weaving Became Mechanized

The power loom was one of the key inventions of the Industrial Revolution. Invented by Edmund Cartwright in 1785, the power loom mechanized the weaving of cloth and, together with the earlier inventions in spinning, completed the transformation of the textile industry from a rural handicraft into a mechanized factory production.

The Need for a Mechanized Loom

By the 1770s, the spinning of yarn had already been partly mechanized by the spinning jenny, the water frame, and the spinning mule. These inventions had dramatically increased the output of yarn, and by the early 1780s the bottleneck in textile production had shifted from spinning to weaving. Weavers could not keep up with the supply of yarn, and cloth was becoming relatively expensive.

The article on the power loom mechanics covers the technical details of the power loom in more detail.

The Effects of the Power Loom

The power loom had several major effects on the textile industry and on society. It greatly increased the productivity of weaving, and it produced cloth of more consistent quality than was possible by hand. It also completed the transformation of the textile industry, since with both spinning and weaving mechanized, the entire process of cloth production could be concentrated in a single factory.

The power loom had a particularly severe effect on the handloom weavers. Before the power loom, weaving had been a relatively well-paid occupation, and many weavers lived comfortably in their own homes. After the power loom, weaving was mechanized, and the wages of handloom weavers fell sharply.

The Power Loom in the Modern Industry

The power loom, in its various forms, has been the standard weaving machine for nearly two centuries. The Northrop loom, introduced in the 1890s, was one of the most important later developments. The Northrop loom, with its automatic weft replenishment, dramatically reduced the amount of labor required to operate a loom, and it became the standard loom of the twentieth century.

Cartwright’s First Patent and Its Limitations

Edmund Cartwright’s first power loom, patented as Patent No. 1,505 on March 6, 1785, was a heavy, hand-built machine that incorporated the basic motions of the weaver’s hand in mechanical form. The device was installed in a mill at Doncaster, where it broke frequently and produced inferior cloth, and it was eventually abandoned. The first patent of 1785, and the second of 1786, were never commercially successful. Cartwright’s subsequent improvement of 1787, which was based on the work of the Manchester mechanics James Kay and John Ainsworth, and the protection of the 1801 patent extension, made the technology more viable, but the real breakthrough came from the work of other engineers. The 1822 Roberts loom of Richard Roberts, who had built a reputation as the most skilled mechanical engineer in Manchester, incorporated a series of improvements — the iron instead of wood frame, the eccentric cam motion for the shuttle, the automatic take-up — that produced a working power loom at a price of £15-20. The Roberts loom, and the modifications made by James Kay of Bury in the 1830s, set the basic form of the power loom for the rest of the nineteenth century.

Productivity, Price, and the Death of the Handloom Weaver

The most striking single fact about the power loom is its productivity. A handloom weaver in 1780 could produce perhaps 1.5 yards of cotton broadcloth per day, working from sunrise to sunset; a power loom in 1820, tended by a single worker, could produce 15-20 yards of similar cloth per day. The productivity gain was roughly an order of magnitude, and it was achieved by replacing human skill with mechanical motion, by allowing the loom to run continuously, and by increasing the speed of the principal motions. The price of a yard of standard cotton cloth fell from about 38 shillings in 1790 to 5 shillings 8 pence by 1830, an 85 percent reduction in real terms. The handloom weavers, unable to compete with the new technology, saw their real wages fall by perhaps 50 to 60 percent between 1810 and 1830, and the 1841 Factory Commission found that of 250,000 handloom weavers still at work in Britain, perhaps 200,000 were earning less than 10 shillings per week. The story of the handloom weavers’ decline is the human cost of the power loom’s success.

The Continental Adoption: France, Saxony, and Switzerland

The British power loom was introduced to the continent under the protection of patent and tariff. The continental European cotton industry, which had been built in the late eighteenth century on the basis of British machinery imported or smuggled out, was slow to mechanize. The first French power looms, imported from England in 1802, were protected by Napoleon’s Berlin Decree of 1806 and the continental system, but the industry did not begin to expand until the 1830s. By 1850 there were perhaps 25,000 power looms in France (against 200,000 in Britain), and the French cotton industry, centered in Mulhouse and the Vosges, was producing high-quality printed calicoes for the European market. Saxony and Silesia, with their established linen and woolen industries, introduced the power loom into the cotton trade in the 1820s and 1830s, and by 1840 Saxony had perhaps 8,000 power looms. Switzerland, with its skilled labor and its neutrality, became a major center of the European cotton industry in the 1840s and 1850s, with a particular concentration in St. Gallen and the eastern cantons. The continental adoption of the power loom is the subject of Pierre Léon’s studies of the French textile industry and of Richard Tilly’s German Industrialization, 1700-1914 (2001).

The Jacquard Attachment and the Pattern Loom

The most important refinement of the power loom in the early nineteenth century was the Jacquard attachment, invented by Joseph Marie Jacquard of Lyon in 1804 and first widely adopted in the French silk industry of Lyon. The Jacquard device, which used a chain of punched cards to control the lifting of individual warp threads, allowed the power loom to produce figured cloth — elaborate patterns of flowers, leaves, and geometric designs — that had previously required the work of a skilled draw-loom weaver. The first Jacquard looms in Britain were imported in 1820, and the technology spread rapidly in the silk trade of Spitalfields and Macclesfield. The Jacquard attachment was later adapted to the power loom and used to produce figured cotton fabrics, especially for the export market. The technology was so important that the French government bought the patent from Jacquard in 1806 and provided him with a pension and royalties, in part because it was thought that the technology would make the Lyon silk industry competitive with the British. The punched card system used in the Jacquard loom was, in turn, a direct ancestor of the punched cards used by Herman Hollerith in his 1890 census tabulating machine, and from there of the tabulating equipment that became IBM’s core product in the twentieth century.

Continuing Relevance: The Power Loom and the Industrial Revolution Debate

The power loom is central to the long-running debate about the causes of the Industrial Revolution. The traditional account, derived from the work of Arnold Toynbee and T. S. Ashton, treated the loom as a “macro-invention” — a single technological breakthrough that made the Industrial Revolution possible. The more recent cliometric literature, including Robert C. Allen’s The British Industrial Revolution in Global Perspective (2009) and Joel Mokyr’s The Lever of Riches (1990), has emphasized the role of many small improvements to the original design and the long process of trial and error by which the loom became commercially viable. The historiographical debate matters because it shapes our understanding of the nature of industrial innovation: was the power loom the product of a single inventive genius, or the cumulative result of decades of small improvements by hundreds of practical mechanics? The answer, in the most recent scholarship, is “both” — the loom was a “macro-invention” in the sense that it was a fundamentally new kind of machine, but it was a “micro-invention” in the sense that it required a long series of small improvements to become a viable industrial technology.

The Japanese Take-Up of the Power Loom

The most consequential late-19th-century development in the power loom was the rapid Japanese adoption of the new technology. The first Japanese cotton-spinning mill, the Kagoshima Spinning Mill, was established in 1867 under the sponsorship of the Satsuma domain, and the industry grew rapidly after the Meiji Restoration of 1868. The Japanese adoption of the power loom was particularly rapid: by 1890 there were perhaps 5,000 power looms in Japan, by 1900 there were 30,000, and by 1910 there were 80,000. The Japanese firms — particularly the Mitsui and Mitsubishi zaibatsu — had adopted the most modern British and American technology, and the Japanese cotton industry, with its low wages and its efficient factory system, became the most productive in the world by 1910. The Japanese share of world cotton exports rose from 0 percent in 1880 to 18 percent in 1900 and 30 percent in 1930, and the Japanese success was one of the principal reasons for the long-term decline of the British cotton industry. The Japanese experience is the subject of Ishikawa Shigeru’s studies and of Takafusa Nakamura’s Senzenki Nihon keizai no seichō to kōzō (1971).

The Cost of the Power Loom and the Capital Intensity of Weaving

The power loom was one of the most expensive machines of the early Industrial Revolution, and the capital cost of the loom was a major factor in the development of the industry. The first power looms, built by Cartwright, cost £20-30 per unit, while the 1820s Roberts loom cost £15-20. The Northrop loom of the 1890s, more complex, cost $300-400 per unit, and the typical weaving shed of 100 Northrop looms cost $30,000-40,000, an enormous capital sum for the period. The capital cost of the loom was a barrier to entry for the small weaver, and it was a major factor in the development of the factory system, since only the large firm could afford to invest in a fleet of looms. The 1840 Factory Inspectorate reported that the average cotton weaving shed in Lancashire had 50-100 looms, and the larger mills had 500-1,000. The capital intensity of the weaving industry was the basis for the modern theory of the firm, and the power loom is one of the standard examples in the economic history literature. The capital cost of the loom is the subject of Alfred D. Chandler Jr.’s Scale and Scope (1990) and of Charles Sabel and Jonathan Zeitlin’s World of Possibilities (1997), which contrast the British and American models of factory organization in the 19th century.

The Twentieth-Century Shuttleless Loom

The most important change in the power loom since the 19th century was the introduction of the shuttleless loom in the 1950s and 1960s. The traditional power loom, in which a wooden shuttle was thrown back and forth across the warp to insert the weft, was a fast, reliable, but relatively slow machine. The Sulzer projectile loom, developed by the Swiss company Sulzer and introduced in 1953, replaced the shuttle with a small projectile that carried the weft across the loom. The Picanol rapier loom, introduced in 1962, used a pair of rapiers to insert the weft, and the Toyota air-jet loom, introduced in 1964, used an air jet to insert the weft. The new shuttleless looms, which were three to five times faster than the traditional power loom, were rapidly adopted in the 1970s and 1980s, and the traditional Northrop loom was largely obsolete by 1990. The shuttleless loom is the subject of Adanur’s Handbook of Weaving (2001) and of the International Textile Manufacturers Federation studies. The 20th-century history of the power loom is a useful corrective to the 19th-century narrative, in which the loom was the central technology of the Industrial Revolution, and it shows the continuity between the 19th-century industry and the modern textile industry.

Reading the Power Loom: A Note on Sources

The history of the power loom rests on a body of primary sources that has been steadily expanded and refined since the 19th century. The principal collections are the Public Record Office in London (now the National Archives), which holds the patent records, the parliamentary papers, the trade returns, and the Factory Inspectorate reports of the period; the British Library, which holds the manuscript collections of many of the inventors and entrepreneurs; the John Rylands Library in Manchester, which holds the papers of the cotton manufacturers; and the Museum of Science and Industry in Manchester, which holds the surviving examples of early power looms. The American equivalents are the American Textile History Museum in Lowell, Massachusetts, and the National Museum of American History in Washington. The standard secondary works are cited throughout this article, but the works of Maxine Berg, Pat Hudson, Stephen Marriner, Geoffrey Timmins, and Christine MacLeod are the most useful starting points. The Pasold Research Fund and the European Association for the History of Textiles are the principal research organizations, and the journal Textile History is the principal venue for new research.
