Question

What do you mean by Spinning Jenny?

Answer 1

Hint: James Hargreaves, a British carpenter and weaver, is credited with inventing the spinning jenny, the hand-powered multiple spinning machine, in 1764. He was the first to improve on the spinning wheel with his invention. Hargreaves figured out a means to increase the thread supply.

Complete answer:
Early multiple-spindle machine for spinning wool or cotton, known as a spinning jenny. James Hargreaves patented the hand-powered spinning jenny in 1770. Though its outcome was inferior to Richard Arkwright's water frame, the development of the spinning wheel into the spinning jenny was a crucial factor in the industrialization of the textile industry.

The technology cut down on the amount of time it took to make cloth by allowing a worker to operate on eight or more spools at once. As technology advanced, this number increased to 120. Until Richard Arkwright built the water-powered water frame, the jenny's yarn was not very strong. The spinning jenny was instrumental in the establishment of the industrial system for cotton production.

Cotton production couldn't keep up with demand in the textile business at the time, so Hargreaves spent time thinking about ways to enhance the process. The flying shuttle had doubled the productivity of the weavers, and now the spinning jenny could meet that need by raising the productivity of the spinners even more. The thread produced by the machine was coarse.

Note: Hargreaves came up with the idea for a metal frame with eight wooden spindles at one end. On that frame, a set of eight rovings was mounted to a beam. When fully extended, the rovings passed through two horizontal wood bars that could be clasped together.
