Who invented the safety pin
THE safety pin was invented by one Walter Hunt. Hunt hit upon the idea of making the safety pin while twisting a piece of wire, trying to think of something that would help him pay off a $ 15 debt. On April 10, 1849, he patented the safety pin.
Hunt thought little of his invention and soon sold the patent for $ 400.
Hunt was a mechanic from New York, whose other inventions include a forerunner of the Winchester repeating rifle, a successful flax spinner, knife sharpener, streetcar bell, hard-coal-burning stove, artificial stone, road sweeping machinery and ice ploughs.
In 1834, Hunt made America's first sewing machine. He later lost interest in patenting the sewing machine because he believed the invention would cause unemployment.
