An 1836 Penny Magazine article, excerpted from Andrew Ure's work on the cotton manufacture, describing the household big wool-wheel (Jersey wheel) and how it was used to spin cotton and wool. It then traces the invention of James Hargreaves' spinning jenny around 1764, including his patent of 1770, the riots against him and his dealings with manufacturers. It closes with a detailed mechanical description of the improved jenny: its spindles, drum, clasp carriage, and winding wire. Three engravings illustrate the Jersey wheel, an Indian cotton-spinning wheel and the jenny.
