Invention of the Paper Bag Machine

For many female inventors in the past several years, the process of invention is twice as difficult as the face of allegations of the world not believing that women can create value in addition to difficulties of invention . Fortunately, for many years, women's inventors like Margaret E. Knight have blown this view out of the water, and they are trying to win honor and recognition.

Born in Maine in 1838, Margaret Knight was brought up by the mother of the widow, and from the very young age trends came from a number of internationally famous inventions. Home Characteristic At the age of 12, Margaret started wearing her first real invention after observing the accident at the textile factory. The knight envisions a device that automatically stops the machine when something is caught. When she was in her teens, the present invention was used in the factory.

After the civil war, Margaret Knight went to work at a paper bag factory in Massachusetts. While working at the factory, Knight thought it would be much easier to wrap it in paper bags (not at the time) if the bottom was flat. This idea affected the machines created by Margaret and turned her into an inventor of a famous woman. The machine of Knight automatically folds and sticks to the bottom of the paper bag - it produces a flat bottom paper bag still used in most grocery stores

Of course, if there is no villain, the story of any victory will not be perfect. In this case, the villain is a man named Charles Annan - he tries to steal Knight's idea (he watches the woman hiring her prototype) and gains patent reliability. Although Margaret did not make a concession without fighting, he appealed to Anan instead and fought for patents that are legally legal. Annan simply thought that women never designed such innovative machines, but Knight showed actual evidence that the invention is truly hers. As a result, Margaret Knight got her patent in 1871.

Knight's invention quickly had a major impact on the paper industry - paper bags began to flourish throughout the retail industry. So far, thousands of machines based on the idea of ​​Margaret Knight are still being used to manufacture flat-bottom paper bags. Cavaliers never stopped there; during her lifetime, she won over 20 patents and came up with almost 100 different inventions including rotating engine, shoe cutter and skirt and skirt. At the time of her death, ob told Cavalier to explain "Edison's lady." In fact, she is bigger - she is a female inventor Margaret Knight.

A book intended for myths and children insists that few people seriously take her inventions for sexual reasons and Anan believes that in court she can not invent flat-bottom paper bags as being women . The recorded fact indicates that it is not so, but at the latter stage of life, the Knight is really lamenting. "Sorry, I can not seize the opportunity like a boy.

Knight moved to Springfield, Massachusetts in 1867 and was hired by a Columbia paper bag. In 1868, the knight invented a machine to fold and bond the paper and made a flat brown paper bag familiar to today's shoppers. Knight made a wooden model of equipment, but a practical iron model was necessary to apply for a patent. Charles Annan, who is building a mechanical studio of Knight Iron model, steals her design and got a patent for that device. Knight raised a patent interference lawsuit in 1871 and acquired a patent. With Massachusetts business partner, Knight founded Eastern Paper Bag Co. and received royalties.
