In America, sewing machines have been further developed. Niels Howe and isaac singer, Americans, independently designed a practical model of an airless sewing machine.
Niels Howe was the first person to make a sewing machine with a needle. There was a hole in the tip of the needle for double-thread chain sewing. As a child, Niels Howe loved all kinds of machinery. When he grew up, he dabbled in various mechanical processes and worked in some machinery factories. By chance, he learned from a friend's conversation that if he invented a machine that could replace manual sewing, he would make a fortune. So, from 184 1, Niels Howe devoted all his energy to the research of sewing machines. After five years of hard work, Niels Howe finally applied for a patent for his sewing machine in 1846.
At first, the sewing machine invented by Niels Howe did not attract the attention of Americans and was not widely popularized because of its difficult operation.
65438+Double-thread chain sewing method in 1930s was later adopted by all sewing machines. Niels Howe was a little disappointed. Before he tapped the potential of sewing machine, he hurriedly transferred the patent right of sewing machine invention to the British. But he didn't give up his research on sewing machines. Later, he went to work in England and continued to improve his invention. After some efforts, his sewing machine can not only process cloth products, but also sew leather and other similar materials. Another American, isaac singer, invented the first practical sewing machine a few years later than Niels Howe. 185 1 year, Singh accepted the job of repairing sewing machines. During the repair, he came up with the idea of making a sewing machine himself. 1 1 days later, he designed an improved prototype and sold it in the name of Shengjia company. This sewing machine is characterized by continuous curve sewing. The presser foot with spring is used to press the cloth to keep it in a good position, and the cloth moves forward with the rotation of the lower roller. In the design of this machine, Singer combined the parts of monier and Howe's machine, which can be operated manually by turning the handle or using the pedal, thus overcoming the difficulties in operation.
Singer's sewing machine was quickly favored by people and quickly swept the United States. Despite such great success, Singh was later accused of stealing Niels Howe's invention. Singh has to pay A Hao a huge sum of money every year for this, but he has not given up the production of sewing machines because of this, and his sewing machine output is still growing.
Singh's success is largely due to his realization that "the more you sell, the greater the profit you get". Therefore, his company has developed a method of manufacturing sewing machines at a low price, adopting mass production technology and installment sales, which is well received by people and the business volume is increasing day by day. By 1860, Shengjia Company has become the largest sewing machine manufacturer in the world.
