US Patent No. 406,598, granted July 9, 1889 to Edward W. Serrell Jr., for an automatic silk-reeling machine. The machine gauges the tension of the thread being reeled from cocoons. When the thread weakens, an electro-magnet circuit advances a magazine of cocoons so that a new filament is attached, keeping the silk uniform in size and strength. A second lever stops the reel when the thread breaks. The document has four sheets of patent drawings, then the specification and five claims.
