United States patent No. 51,988 (January 9, 1866) for a method and machine for drawing and reeling silk directly from living spiders, especially a golden-silk field spider (Nephila) found on the South Carolina sea islands, and from silkworms or other silk-producers. The specification describes a rotating notched wheel that holds the spiders by their legs with an elastic band and leaf springs. Guides, a roller, a belt-driven spool and a worm-gear traverse wind the thread, and a lever and tooth stop-motion halts the wheel when a thread breaks. Two sheets of patent drawings (Figs. 1-4) accompany the text, which ends with two claims.
