![]() The thread is twisted in its rotation before a new loop is started. In this patent the revolving hook takes the loop of thread and holds it while the feed moves the fabric until the needle descends once more through the loop. ![]() ![]() James Gibbs took out two patents (Decemand January 20, 1857), before the all important patent above, from June 2, 1857. Willcox was impressed with Gibbs' machine and put him to work with his own son, Charles Willcox. Having been to Washington's patent office he went to Philadelphia to show his model to James Willcox, who was specializing in building models of new inventions. His work on it had to fit around his employment and he was hampered by a lack of tools and materials, but by April of that year his first model was ready and his employers agreed to finance the patenting of it. To him it looked too heavy and expensive and he decided to pursue his idea of a simpler, lightweight chainstitch machine. In January 1856 while visiting his father he saw a Singer machine in a tailor's shop for the first time. He could tell the needle went in and out of the same hole in the fabric, rather than travelling completely through as in hand sewing, and came up with the idea that sewing had to have been accomplished with a chainstitch. The picture only showed the top half of the machine, so Gibbs tried to imagine how a stitch was formed. James Gibbs had originally seen a woodcut picture of a Grover & Baker machine in 1855.
