US Patent No. 334,617, granted January 19, 1886 to Edward W. Serrell Jr. of New York, then living in Chabeuil, France, for an improvement in silk-reeling machinery. It describes a three-drum arrangement of different diameters, with a spring-loaded pivoted lever and guide pulleys, that compensates for thread stretch after the croisure. The thread's tension on the lever then closes an electric circuit that adds cocoon filaments when the thread falls below standard size. Two sheets of drawings (Figs. 1-3) are followed by the specification and three claims.
