The first sewing machine was invented in 1790 and patented by the British inventor Thomas Saint. Some time earlier, in 1755, Karl Weisenthal, a German inventor, devised the first sewing macine needle, but did not produce a complete machine. Saint's machine, which was designed to sew leather and canvas, mainly on boots, used only a single thread and formed a chain stitch. Instead of a needle, an awl was employed to pierce a hole through the material being sewed. Another mechanism placed the thread over the hole, and then a needlelike rod with a forked point carried the thread through to the underside of the work, where a hook caught the thread and moved it forward for the next stitch.When the cycle was repeated, a second loop was formed on the underside of the cloth with the first loop, thus forming a chain and locking the stitch. Saint's machine, however, never progressed beyond the patent model stage. And it overlooked the Weisenthal needle design.
