Margaret A. Knight

Margaret Knight was born on February 14, 1838 in Yorkshire Maine and was born at James and Hannah (Till) Knight. Mr. Knight and her brothers Charlie and Jim were brought up by her widow 's mother in Manchester, New Hampshire. Mr. Knight has always been interested in making things and inventions, attracting attention to machinery at the textile factory. Prior to her teens her first invention was used in the factory. Mr. Knight moved to Springfield, Massachusetts and worked for a Columbia paper bag company after the Civil War. Here she invented a machine for folding and gluing paper to form the bottom of a bag or flat bottom bag. She studied the machine at the factory during the day and made drawings and models at her accommodation in the evening. The bagging machine of Margaret Knight got a patent with patent number 116, 842 on July 11, 1871.

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
