All About Sewing Machines
Prior to the invention of sewing machines, clothes and other materials were sewn by hand. Hand sewing is an art form that was practiced over 20,000 years ago. During those days, sewing needles made of bone or animal horns and thread made of animal sinew were used. In the beginning of 14th century, iron needles were invented and later in the 15th century eyed needles were introduced.
It is believed that the first known attempt for a workable sewing machine was framed in 1790 by Thomas Saint. In 1800, sewing machine was invented and by the mid-nineteenth century it became popular among the public. After Thomas Saint, various attempts were made for inventing a sewing machine. But, all of them turned unsuccessful.
In 1830, Barthlemy Thimonnier-a French tailor- came out with the first functional sewing machine. It used only one thread and a hooked needle for a chain stitch. Later in 1834, Walter Hunt came with an idea for double-thread sewing machine and it was regarded as America's first successful sewing machine. The machine devised by Walter Hunt was a straight-seam sewing machine that used reciprocating eye-pointed needle and an oscillating shuttle.
Following Walter Hunt, Elias Howe developed a machine which had the same features as that of Hunt's sewing machine. After Elias Howe, Isaac Merit Singer patented a similar machine and was regarded as the first commercially successful machine. Singer's machine included a straight eye-pointed needle and transverse shuttle, a table to support the cloth horizontally, a vertical presser foot to hold the material against the upward stroke of the needle, and an overhanging arm to hold the presser foot. Instead of a hand crank, Singer's machine used a foot treadle similar to that of a spinning wheel. Helen Augusta Blanchard, Allen Wilson, John Bradshaw, Charles Miller, and James Edward Allen Gibbs were the other contributors who produced a remarkable framework for sewing machines.
Types of Sewing Machines
There are three types of sewing machines- mechanical sewing machines, electronic sewing machines, and computerized sewing machines. Since their introduction in 1800 till 1960's, all sewing machines were mechanical. Mechanical sewing machines are controlled by a rotary wheel. They have knobs and dials to make changes in the tension or the length or width of the stitch.
