The spinning jenny is a multi-spool spinning wheel. It was invented circa 1764 by James Hargreaves in Stanhill, near Blackburn, Lancashire in the northwest of England (although Thomas Highs and Richard Arkwright are other candidates identified as the inventor). The device dramatically reduced the amount of work needed to produce yarn, with a single worker able to work eight or more spools at once.
Components
The idea was developed as a machine with eight wooden spindles at one end, spun from a much larger wheel at the other. A set of eight rovings were attached to a beam that could roll. A clamp-like device in the roving beam allowed the operator to then release all the threads at once, to be collected. The flying shuttle had increased yarn demand by the weavers by doubling their productivity, and now the spinning jenny could supply that demand by increasing the spinners' productivity even more. The machines were often operated by children, who could more easily move about them to fix the long wooden spindles. The machine produced coarse yarn that lacked strength, but it was still suitable for the making of fabric.
History
James Hargreaves invented the Spinning Jenny. He was born in Oswaldtwistle, near Blackburn, in 1720.
At the time cotton production could not keep up with demand, and Hargreaves spent some time considering how to improve the process. The most common story told about the invention of the device is that his daughter, Jenny, knocked over one of their own spinning wheels. The device kept working as normal, with the spindle now pointed upright. Hargreaves realized there was no particular reason the spindles had to be horizontal, as they always had been, and he could place them vertically in a row.
The name is variously said to derive from this tale
Success
Hargreaves kept the machine secret for some time, but he produced a number for his own growing industry. The price of yarn fell, angering the large spinning community in Blackburn. Eventually they broke into his house and smashed his machines, forcing him to flee to Nottingham in 1768. There he set up shop producing jennies in secret for one Mr. Shipley, with the assistance of a joiner named James.
Eventually Hargreaves applied for a patent on the jenny in July 1770. By this time a number of spinners in Lancashire were already using copies of the machine, and Hargreaves sent notice that he was taking legal action against them. The manufacturers met, and offered Hargreaves £3000. He at first demanded £7000, and at last stood out for £4000, but the case eventually fell apart when it was learned he had already sold several in the past.
Hargreaves' died in April 22, 1778.
The spinning jenny was a huge success due to the fact that it could hold more than one ball of yarn, therefore making more clothing materials in a shorter amount of time while reducing the overall cost.
