Spinning Jenny

Detailed explanation-1: -James Hargreaves’ ‘Spinning Jenny’, the patent for which is shown here, would revolutionise the process of cotton spinning. The machine used eight spindles onto which the thread was spun, so by turning a single wheel, the operator could now spin eight threads at once.
Detailed explanation-2: -This was a multi-spindle spinning machine. It meant that a spinner could produce more yarn at a time of increased demand from weavers involved in the manufacture of cloth.
Detailed explanation-3: -The word jenny is an old world word used as a reference to an engine. There is some indication that James Hargreaves worked with Thomas High to improve on an earlier invention of a mechanical spinning wheel and improved the design which was then named a spinning Jenny after Thomas High’s daughter.
Detailed explanation-4: -The machine replaced the need for manual labour and enabled the production of inexpensive spun cotton by using the moving force of a creek or river that spun a shaft.
Detailed explanation-5: -The idea was developed by Hargreaves as a metal frame with eight wooden spindles at one end. A set of eight rovings was attached to a beam on that frame. The rovings when extended passed through two horizontal bars of wood that could be clasped together.
Detailed explanation-6: -The ‘Spinning Jenny’ is a spinning machine with multiple spinning frames. This allowed the workers to work with eight or more spools of thread at once. As the technology improved more and more spools were added greatly increasing the amount of cloth produced for the same amount of effort.
