PATENT GASSED THREAD

The process of gassing cotton yarns was devised by Samuel Hall in 1817. Patent No. 4177 was for the thread and No. 4178 was for gauze or cloth, or lace. He marketed his patent gassed thread under the name of G. F. Uriing & Co., London, in the same year. This process was so successful that Mr. Hall received ???10,000 to ???15,000 yearly by gassing other maker's goods at three farthings per square yard.
