Safety pin. History of invention and production
Directory / The history of technology, technology, objects around us English (safety) pin - a kind of pin, a safe device in the form of a needle connected to a rod that has a cap at the end. It is used for pinning, pinning pieces of soft tissue and other soft materials. It can also be a fashion accessory and be made of gold or silver, sometimes with rhinestones or precious stones.
The American engineer Walter Hunt invented the safety pin in its current form on April 10, 1849. The rights to use it were hastily sold for $400 (about $10000 in 2008 prices) to pay Hunt's $15 debt (U.S. Patent #6,281, April 10, 1849). However, in those days, a patent did not always protect the inventor. Already in the autumn of the same year, an enterprising Briton (Charles Rowley) patented an analogue of Hunt's pin in his homeland. Therefore, now all over the world this pin is called "English". A safety pin can be an element of decorative toilet items: brooches, badges, etc. Walter Hunt has made more inventions than anyone else in the world. Among them are a sewing machine, a fountain pen and a safety pin. Walter Hunt was born in 1796. Raised with 12 of his siblings, he was educated at a local school in Martinsburg, New York, became a bricklayer at age 21, and began working for the Louisville textile manufacturing community. However, it quickly became clear that his talent was much wider - he repeatedly helped to improve the spinning process, and in 1826 he received a patent for a new design of a spinning machine and went to New York to look for money for its production. Instead, he sold all the patent rights, and it became his signature style for life. In New York, Hunt witnessed a girl run over by a cab because the cabman's hands were busy with the reins and he could not sound the horn. After returning to Louisville, Walter invented and patented a gong controlled by a foot pedal. A year later, he sold this patent as well and finally moved to New York, where he became a real estate agent to support his family. However, this did not prevent his passion for invention. Over the next few years, Hunt patented a compact knife sharpener, ball wheels for furniture, and a charcoal stove for heating. He sold all the rights to these inventions, as before. In 1833, he made his most famous invention - the sewing machine. However, he did not patent or manufacture, and instead sold all rights to George Arrow-Smith. But it was not possible to start production because of the crisis. As a result, the sewing machine was patented only in 1846 by a completely different inventor - Elias Howe. Under pressure from family and friends, Hunt applied to the patent office in 1853, and in 1854 his priority was officially recognized, although he did not receive a cent from it. (However, in 1858, Isaac Singer, the largest manufacturer of sewing machines, agreed to pay $50000 to Hunt for the use of his invention, but did not manage to do this before the inventor's death.) But Hunt did not lose heart and continued to invent and receive patents in various fields. Among his inventions are buckles for belts and suspenders, a tree saw, an ice plow for ships, a machine for making shoe nails, an inkwell and fountain pen, paper collars, and an explosion-proof lamp. He invented the weapon reloading system and the cartridge that Smith & Wesson later adapted, as well as the upside down ceiling walking system used by circus performers.
One of his most famous inventions was made when he twisted a piece of wire in his hands, thinking about how to pay off a $15 debt. Suddenly, he came up with the idea of how to make a safety pin that would not “creep” out of clothing and would not prick. It has survived to this day almost in its original form - with a latch and a pair of spring coils. Hunt, as usual, sold the pin patent for $100. How much pin manufacturers have earned on this, history is silent. Walter Hunt died on June 8, 1859 from pneumonia - although a poor, but very respected man. Author: S.Apresov
