The First Lock Stitch Sewing Machine
Elias Howe (1845)
This is a sewing machine developed in 1845 by Elias Howe in the United States. It is the basis of today's lock stitch sewing machines which employ the technology to stitch with a needle thread and a bobbin thread. His invention of the shuttle and the bobbin and idea of stitching a fabric by adjusting the timing of a needle, threads, and a shuttle hook especially outclassed conventional ideas.
