Paper read to the Royal Society on 1 Feb. 1759 in which the Rev. Samuel Pullein describes a simplified silk-reeling machine intended to help silk culture in the American colonies. He explains the 'Vitrage' problem (gummed-together rounds of silk thread on the reel), compares band-driven reels with the Piedmontese toothed-wheel reel, and presents his version using only two toothed wheels and a winch-driven guidestick. He also describes a swivel-cross device for making the double croisure (twist) of the two threads. Two engraved plates (Tab. II and III) show the Piedmontese reel and his new design.
