The Howe machine has a needle with an eye near the point. The thread carried through the cloth by this needle forms a loop under the cloth through which a shuttle passes. The shuttle contains a bobbin of thread, which unwinds as it passes through the loop, and the thread thus put through forms the lock-stitch. In addition to machines for ordinary sewing, there are many special inventions. The most important is the cylinder, with cylindrical feed, for shoe-work, gloves, pocket-books, and traveling-bags. Sewing-machines are now produced that make 2,000 stitches a minute. The button-hole machine can make 1,200 stitches per minute. Sewing-machines are usually fitted with a treadle, to be worked by the foot.
