Who invented Jenny spinning machine?
1768 J. Hargreaves in Nottingham joint venture with others to start a spinning workshop, with Jenny spinning machine production of knitted yarn. Because he did not apply for a patent, so only their own production "Jenny machine" to make money. "Jenny machine" is not only efficient, and the quality of spinning yarn is also better, so Hargreaves business is good, "Jenny machine" is also gradually spread out.
In 1768, Hargreaves won the patent; by 1784, "Jenny machine" has increased to eight spindles. Four years later the United Kingdom has twenty thousand "Jenny machine".
He suddenly thought: if a few spindles are arranged vertically, with a spinning wheel driven, not all of a sudden spinning more yarn it? Hargreaves was very excited and tried to do it right away. In the following year he made a new spinning machine with eight spinning spindles with a spinning wheel, and the effect was eight times higher. 1764 made to his daughter Jenny named spinning machine. This is the first multi-spindle hand spinning machine, equipped with eight spindles, with a roller feed fiber strip, suitable for cotton, wool, hemp fiber spinning. The emergence of Jenny's spinning machine caused a lot of hand-spinning spurs at the time, and they rushed into the home of Hargreaves to destroy the machine.
Things start from the day of 1764. England Lancashire has a textile worker James Hargreaves, that night he went home, opened the door after accidentally kicked his wife is using the spinning machine, when his first reaction is to hurry Spinning machine righting. But when he bent down, but suddenly shocked, and he saw that the spinning was spinning the spinning machine is still turning, but the original sideways of the yarn now become upright.
In the mid-18th century, British goods were increasingly sold overseas, and the production of handmade workshops was inadequate. In order to increase production, people find ways to improve production technology. In the cotton textile sector, people first invented a shuttle called the weaving tool, greatly accelerated the speed of the weaving, but also to stimulate the demand for cotton yarn. In the 1860s, the weaver Hagreaves invented the "jenny machine" hand spinning machine. "Jenny machine" can be spinning a lot of cotton thread, greatly improving the productivity.
