spinning jenny

spinning wool since 1770

INVENTOR

James Hargreaves

How does it work:

Through the use of a moving bar that was operated by a foot pedal, the cotton fibers were drawn out. The fibers were then twisted lightly and spun onto eight separate spindles. Unlike the yarn produced on a hand-spun wheel.


Purpose

John Kay's fly shuttle had doubled the amount of cloth weavers could produce, and the jenny supplied the weavers with enough thread to make the cloth.

WHERE

At the time he devised the machine, he was a poor, uneducated spinner and weaver living at Stanhill , near Blackburn, Lancashire.

WHEN

About 1764 Hargreaves is said to have conceived the idea for his hand-powered multiple spinning machine but he did not receive his first patent for the jenny until July 12, 1770.

why is there a need

permitted large-scale manufacture of high-quality thread for the textile industry. Crompton’s machine made it possible for a single operator to work more than 1,000 spindles simultaneously

IMPORTANCE

Made it possible for one man to weave material wider than the length of his extended arm that could make material so wide that two or even three men would previously have been required to cast the shuttle back and forth.
