Spinning Jenny

The spinning jenny is a multi-spindle spinning frame that allowed a single worker to spin thread on eight or more spindles at once, eventually as many as 120, and it was one of the key inventions that industrialized textile manufacturing during the early stages of the Industrial Revolution. It was invented in 1764 or 1765 by James Hargreaves in Stanhill, Oswaldtwistle, in Lancashire, England, and it addressed a bottleneck in yarn supply created by John Kay's flying shuttle of 1733, which had doubled the output of hand weavers; the yarn the jenny produced was initially too weak for some uses until Richard Arkwright's water frame improved on the process.
