WORLD HISTORY

Detailed explanation-1: -About 1764 Hargreaves is said to have conceived the idea for his hand-powered multiple spinning machine when he observed a spinning wheel that had been accidentally overturned by his young daughter Jenny.

Detailed explanation-2: -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-3: -Spinning Jenny was invented by James Hargreaves in 1764. The spinning jenny is a multi-spindle spinning frame, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution.

Detailed explanation-4: -The spinning jenny allowed more threads and yarns to be produced by fewer spinners. The early spinning jenny also produced a weaker thread than could be produced by hand so there was a decrease in quality until improvements were made to the machines and a dependable power source became available.

Detailed explanation-5: -James Hargreaves invented the spinning jenny in order to be able to spin more thread at one time. He got the idea for his invention when a spinning frame was knocked over and the wheel and the spindle continued to spin. He designed and built a spinning frame that held multiple spindles upright in a row.
