Sewing machine

In 1842, the first U.S. patent (of which there is any record) for a sewing machine was issued to John J. Greenough of Washington, DC. (No. 2,466) as "A Machine for Sewing or Stitching all Kinds of Straight Seams." The needle was gradually tapered to a point at each end, with an eye in the middle. It used pairs of pinchers, one on each side of the work to alternately draw the thread back and forth. It did not use thread from a bobbin of thread. Instead, the lengths of thread were inserted in the needle, similar in length to those used in hand sewing.*
