US PATENTS IN 1842 

DESCRIPTIONS AND CLAIMS OF SEVERAL 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.

Knitting stockings

I shall claim:

1. The method above described and represented in Figs. 14, 15 and 16, of forming the hinges or joints by which the bars of the needles or hooks of the endless belt are united so that any one wire, with its hooked needle may be removed or another wire may be added to the collection for the purposes herein set forth.

2. Forming the directing nippers, by which the yarn is conveyed from the bobbin to the endless belt, of two lips or spring blades y, y, Figs. 11, 12 and 23, which receive the yarn between them and permit it to be delivered through their ends in con tact, the same being constructed and operating in all respects substantially as set forth.

3. The combination of the sliding plate m (moved by a spring lever nor other similar contrivance) with the clicks or pawls R, S and the lever z of the directing nippers, the same being arranged substantially in the manner set forth and for the purpose of causing, by one operation or lateral movement of the lever n, the machinery to knit in an opposite direction.

4. The method of sustaining the endless belt of knitting wires upon its moving pinion by means of the combined arrangement of machinery retaining it in said position, said arrangement consisting of the lip m', spring n and roller o'. In testimony that the foregoing is a true description of my said invention and improvements I have hereto set my signature this twenty-third day of February, in the year, eighteen hundred and forty-two.
