Margaret Knight (1838-1914), Inventor of Paper Grocery Bag

Margaret Knight was born in Maine State York in 1838. As a child, she liked designing various kinds of toys for himself and her brothers and sisters.

Her father passed away at the age of twelve, and she went to work at the textile factory to help her family. One day while working, the stuck thread jumped out the space shuttle from the mooring along the processing line, and the workers were injured. Based on what Nat observed, she continued to suggest a way to create a covered space shuttle so that no such accident would occur. She did not know the patent at that time, so the company continued using her idea, but she did not profit from it.

By 1868 she worked at a Columbia paper bag company in Springfield, Massachusetts. At that time, the paper bag was flat with an opening like an envelope. Knight thinks that a square bottom bag is more convenient, but I realized that it is necessary to fold the paper automatically and bond the bottom. She started trying to change the current bag making machine used in the factory to complete this work.

First she made a wooden model, but in order to apply for a patent she needed a working model made of iron. She brought the project to a Boston machining plant where Charles Annan, one of the workers, stealed the idea and applied for a patent. Knight was able to file a lawsuit against Annan and acquired a patent in 1871.

In 1870, her and business partners decided to set up a company to make their own bags. Workers are hard to follow her instructions because women feel that they do not know how to move the machine. However, Knight is prevalent in the manufacture of Oriental paper bags.

Knight continues to produce many other useful products. Most of them are related to manufacturing. One for drilling machines, one for numbering machines, the other for windows and sashes. In the mid-1990s, she promised to make a better shoe making machine. She is over 60 years old, but when the car entered herself, she was fascinated by them and got a patent for a series of improvements to the rotor engine.

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

If you have used paper bags, you can thank Margaret "Mattie" Knight, the inventor of the most famous female in the 19th century. Born in Maine Yorkshire, Nairn is best known for her machine made at age 30, folded and pasted on paper to form a flat bottom paper bag. The product is very popular - in fact, it is very popular and the man steals his patent idea. When Knight took him to the court for patent intervention, he thought that the woman could not understand the complexity of the machine. Knight won her case by providing evidence of his design machine and giving him the right to patent his machine. During her career, Knight invented over 100 different machines and received 20 patents including a window frame with rotary engines, shoe cutters and sashes. However, if the real test of the invention is its durability, the knight's paper bag - still in use today - has proved her a wonderful gift

Yes, today's kids owe their brown paper doll and cheap BANG at Margaret "Mattie" night (1838 - 1914). But long before she turned to personal small cargo transport, Knight was visiting a cotton factory. So, her brother was a supervisor. One day she saw the shuttle line from the spool and stabbed a little boy. This is obviously common. Cavaliers had some experience in assembling kites and sleds, decided to stop the danger of the space shuttle and designed a device to prevent such accidents (details were lost in history). She is 12 years old and I do not know anything about patents or lawsuits. The equipment was adopted at the cotton factory nationwide, but Knight did not benefit from her work.
