In 1764, a British carpenter and weaver named James Hargreaves invented an improved
spinning jenny, a hand-powered multiple spinning machine that was the first machine to improve upon the
spinning wheel by making it possible to spin more than one ball of yarn or thread.{p]
Spinner machines like the spinning wheel and the spinning jenny made the threads and yarns used by weavers in their looms. As weaving looms became faster, inventors had to find ways for spinners to keep up.
