US PATENTS IN 1842
DESCRIPTIONS AND CLAIMS OF AMERICAN PATENTS ISSUED IN THE YEAR 1842
Sewing Machine. In 1842, John J. Greenough received the "first American patent" for a sewing machine. Greenough’s patent model used a needle with two points and an eye in the middle. To make a stitch, the needle would completely pass through the material by means of a pair of pinchers on either side of the seam. The pinchers traveled on a rack and opened and closed automatically. The needle was threaded with a length of thread and required constant rethreading.
