Walter Hunt (July 29, 1796 – June 8, 1859) was an American mechanical engineer. Through the course of his work he became known for being a prolific inventor. He got first involved with mechanical innovations in a linseed producing community in New York state that had flax mills. While in New York City to promote his inventions he got involved in inventing the streetcar gong that was used throughout the United States. This then led him to invent other useful items like the safety pin and sewing machine. He invented the precursor to the repeating rifle and fountain pen. About two dozen of his inventions are used today in basically the same form as he had patented them. In spite of his many useful innovative creations he never became wealthy since he sold off most of his patent rights to others at low prices with no future royalties. Others made millions of dollars from his safety pin device.
Early life and education
Walter Hunt was born July 29, 1796, in the town of Martinsburg, in Lewis County in the state of New York. He was the first born child of Sherman Hunt and Rachel Hunt. He had twelve siblings. Hunt received his childhood education in a one-room schoolhouse. Hunt was muscular, tall and slender with a ruddy complexion. He married Polly Loucks in 1814 and they had four children. Hunt went to college and earned a master's degree in masonry in 1817 at the age of 21.
Mid life
Hunt traveled to New York City in 1826 to get money for one of his inventions. While there he witnessed an accident where a horse-drawn carriage ran over a child. The accident event motivated him to come up with a metal bell that was operated with a hammer that could be controlled by one of driver's feet without letting go of the horse reins. Hunt patented his new innovation on July 30, 1827. He promoted his concept to many prospects and eventually was able to sell his foot operated coach alarm mechanism idea to the stagecoach operators Kipp and Brown. Hunt's innovation was soon adopted by most public horse-drawn vehicles throughout the city. Hunt's coach alarm was further developed and used throughout the United States.
Inventions
Hunt was a prolific inventor. From 1827 to 1830, while earning a living in the real estate field, he invented a fire engine, an improvement for hard coal-burning stoves, the first home knife sharpener, and a restaurant steam table apparatus. He also invented the precursor of the Winchester repeating rifle and the forerunner of the American fountain pen as used in the twentieth century. Additionally, Hunt invented a flax spinner, an improved oil lamp, artificial stone, the first rotary street sweeping machine, mail sorting machinery, velocipedes, and ice plows. He also made improvements to guns, cylindro-conoidal bullets, ice-breaking wooden hull boats, paraffin oil candles, velocipedes, machines for making rivets and nails, and self-closing inkwells. He also invented the Antipodean Performers suction-cup shoes claimed to be used by circus performers to ascend up solid side walls and walk upside down across high ceilings. He did not realize the significance of many of his inventions when he produced them and sold off most of his patent rights to others for low prices making little for himself in the long run. In the twentieth century many of his patented devices were widely used everyday common products.
Sewing machine
He developed the first modern feasible operating sewing machine sometime between the years 1835 and 1837 at his Amos Street shop that was up a narrow alley in Abingdon Square at the borough of Manhattan in the city of New York. He manufactured and sold a few of these machines at the time. He never initially patented the mechanical device he created that used a lockstitch for sewing. It had a characteristic of an eye-pointed needle and used two threads whereby one thread passed through a twisted loop in the other thread and then both interlocked. The uniqueness of this was that it was the initial time an engineer or technician inventor had not imitated a single stitch done by hand and used two interlocking threads at a seam. He used a technique for sewing which was revolutionary at the time. The eye opening was near the point of the needle and operated on a vibrating arm and a loop was formed under the cloth by this thread through which a shuttle, reeling off another thread, was forced back and forth making an interlocked stitch. Hunt completed his working model before he showed it to anyone.
