SEWING MACHINE

any of various machines for stitching material (such as cloth or leather), usually having a needle and shuttle to carry thread and powered by treadle, waterpower, or electricity. It was the first widely distributed mechanical home appliance and has been an important industrial machine. An early sewing machine was designed and manufactured by Barthlemy Thimonnier of France in 1841 to mass-produce uniforms for the French Army, but rioting tailors destroyed the machines. Thimonnier's design, in any event, merely mechanized the hand-sewing operation; a decisive improvement was embodied in a sewing machine built by Walter Hunt of New York City in about 183234 but never patented, and independently by Elias Howe of Spencer, Mass., and patented in 1846. In both machines a curved eye-pointed needle moved in an arc as it carried the thread through the fabric, on the other side of which it interlocked with a second thread carried by a shuttle running back and forth on a track. Howe's highly successful machine was widely copied, leading to extensive patent litigation and ultimately to a patent pool that included the design of Isaac Merrit Singer, the largest manufacturer. In 1860 more than 110,000 sewing machines were produced in the United States alone. Although modern sewing machine designs have proliferated in an enormous variety, mostly for special industrial purposes, the basic operation remains unchanged. Modern machines are commonly powered by an electric motor, but the foot-treadle machine is still in wide use in much of the world. The world's largest producer is China. Japan's industry pioneered the versatile zigzag machine.
