US Patent No. 1,022,097, granted April 2, 1912 to Carl Rudolph Linkmeyer of Bremen, Germany, for a process of making fine artificial threads (rayon) from cupro-ammonium cellulose solutions. The process draws a very viscous solution into fine filaments and coagulates them fully in a single precipitating bath, so the threads can be spooled at once. The patent describes the apparatus (glass tube spinnerets, funnel-shaped vessel, inclined tube, pump and tanks), gives example solution and bath compositions, and lists three claims. It includes one drawing sheet.
