Hand spinning on these types of wheels, both hands are free (since the wheel is turned with a treadle, rather than by hand), so the spinner can use one hand to draft the fibres and the other to wet them. Modern powered spinning, originally done by water or steam power but now done by electricity, is vastly faster than hand-spinning. The spinning jenny, a multi-spool spinning wheel invented c. 1764 by James Hargreaves, dramatically reduced the amount of work needed to produce yarn of high consistency, with a single worker able to work eight or more spools at once. At roughly the
Spinning frame supplies became scarce especially due to innovations such as the doubling of the loom speed after the invention of the flying shuttle. High demand for yarn spurred invention of the spinning jenny in 1764, followed closely by the invention of the spinning frame, later developed into the water frame (patented in 1769). Mechanisms had increased production of yarn so dramatically that by 1830 the yarn cottage industry in England could no longer compete and all spinning was carried out in factories. Richard Arkwright employed John Kay to produce a new spinning machine that Kay had worked on with (or possibly
