US Patent No. 702,163, granted June 10, 1902 to Robert Wilhelm Strehlenert of Stockholm, for an apparatus that spins artificial silk filaments into strands or threads. Revolving and rotating mouthpieces dip into a liquid reservoir so the filaments twist together as they form, and a broken filament is caught and twisted in without stopping the machine. The patent describes batch and continuous versions plus a horizontal variant, and ends with six claims. It includes two sheets of drawings (Figs. 1, 1a, 1b, 2 and 3).
