The Spinning Jenny
Transcript of The Spinning Jenny
Hargreaves About the Invention How the Spinning Jenny works Positive effects of the Spinning Jenny So... Who's "Jenny"? Industrial Revolution Inventor,
James Hargreaves. James' birth date is unknown.
All we know is that he was baptized on January 8, 1720.
He was born in England.
Lived in the town of Blackburn.
James didn't receive proper education, so he never knew how to read or write.
He was poor, but worked as a weaver and carpenter.
James really wanted to be an engineer. The Spinning Jenny was one of the first
steps to mass production.
The Spinning Jenny was used to replace the spinning wheel.
The new machine used eight spindles, compared to one.
By turning a single wheel, the operator could now spin eight threads at once.
The idea of the Spinning Jenny came from Hargeaves' daughter or wife, Jenny. Apparently, Jenny knocked over the normal spinning wheel. The spindle, was thrown from a horizontal to an upright position, continued to whirl. He then realized that vertical rows of spindles could be put onto one wheel to spin wool and cotton at a faster pace.
(No one is sure if that is true or not.) http://videos.howstuffworks.com/discovery/31667-industrial-revelations-spinning-jenny-video.htm Reduced the amount of time it took to spin cotton.
Increased the production of textile.
Eight spools of yarn were produced at once, instead of a single spool.
Made things much easier for workers and weavers.
Clothes were made much faster.
The yarn was better quality.
Negative effects of the
Spinning Jenny Hargreaves tried to keep his invention a secret but ended up selling a few to buy things for his family. Some businesses used the Spinning Jennies which decreased the need for workers.
The workers then rebelled against the new machine because they were taken away from their jobs.
Many, angry workers broke into James' home and destroyed all the spinning jenny's they could find.
James tried to protect his invention but never received a patent.
In the end, James didn't received anything for his invention.
