The Spinning Jenny
hh
The Spinning Jenny is a multi-spindle spinning frame, and was one of the key developments in weaving production during the early Industrial Revolution. It was invented in 1764 by James Hargreaves in Stanhill, Oswaldtwistle, Lancashire in England. The device reduced the amount of work needed to produce cloth, with a worker able to work eight or more spools at once. This grew to 120 as technology advanced. The yarn produced by the Jenny was not very strong until Richard Arkwright invented the water-powered 'Water Frame', which produced yarn harder and stronger than that of the initial Spinning Jenny. It ushered in the factory system.

“James Hargreaves invented the Spinning Jenny, and Richard Arkwright pioneered the water propelled spinning frame which led to the mass production of cotton. This was truly revolutionary.
The cotton manufacturers created a whole new class of people:- the urban proletariat. The structure of society itself would never be the same.”
