Arkwright’s textile machines

They may look basic, but these machines helped bring about a revolution – the Industrial Revolution no less! These were the machines that Ned Ludd – founder of the Luddites movement protested so violently against. He realised that by mechanising certain processes, there would be massive social upheaval as people were replaced by machines. You can see these examples for yourself at London’s Science Museum in South Kensington.

Richard Arkwright developed these innovations (not inventions – they had precursors) into a system between 1765 and 1775 – about the time Capt James Cook was checking out the transit of venus and checking out the east coast of Australia. The system came to be known as the textile mill or factory.

This concept arose from his appreciation that the manufacture of cotton yarn was a series of discrete operations that could be carried out by special purpose machines, brought together in one place and driven from a single power source, such as a water mill, or later, a steam engine. Before this time, most textiles were produced individually in cottage industries by spinners and weavers. The production of cotton lagged way behind that of wool or linen.

But there were impacts. The factory system brought England to the forefront of textile manufacturing in the nineteenth century, but it also brought about the collapse of the of the Indian cotton industry – while demand for raw cotton sustained the slave economy in the USA.

Carding machine
According to the museum info cards the carding machine disentangles, loosens and straightens the cotton fibres. The fibres are fed between two drums which are covered with leather ‘cards’ embedded with bent wire teeth. A third drum strips off the fibres in a continuous sheet which is then lifted off to form a ‘sliver’.

Lantern drawing frame
The sliver is then passed to the lantern frame where it is elongated and narrowed, while being twisted to that it becomes strong enough to handle. The sliver is then called a ‘roving’ or ‘slubbing’ (hence the term ‘slub linen’).

Four spool and eight spool spinning machines
The four spool machine closely resembles the design Arkwright patented in 1769. Both machines spin yarnfrom teh cotton rovings produced by the drawing frame.

The later eight-spooled machine effectively doubled output. Both were powered by water wheels.

The eight-spool machine was effectively two four-spool machines joined together.
