Two pages from The Textile Mercury (January 1890) describing the Silent Simplex spinning mule made by Richard Threlfall of Bolton, for medium and low counts with some motions for finer counts. The article covers the frame, headstock, drawing-up and backing-off gear, cam shaft, quadrant and safety features, and includes front and back view engravings. The second page also starts a Foreign Correspondence column on wool and textile trade conditions in Antwerp, Berlin, Chemnitz, Fourmies and Lyons, with French silk import and export tables for 1881-1889.
