sewing machine
It was over 1500 years later in 1790, that the first workable sewing machine was invented and patented by the British inventor Thomas Saint. 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.
