This Wilcox and Gibbs treadle machine carries a patent date of 1857. We found this machine in Perry, NY at one of our favorite collectible stores.
In 1856 James Gibbs obtained a patent for a sewing machine that would produce a chain stitch. This machine has no bobbin and therefore, makes a chain stitch. Lockstitch machines gained popularity over the chain stitch machines because the stitching doesn't unravel as easily.
