Two pages from Textiles, vol. 15 (pp. 14-15). The first is part of Samuel S. Dale's series on yarn number calculations, giving conversion formulas between yarn counting systems (runs, cotton, worsted, West of England, linen, Yorkshire, yards per pound, metric), with denier, dram, grains and jute equivalents. The second page carries an unrelated installment of W. Scott Taggart's 'The Mechanics of Textile Processes', covering levers, centers of gravity, moments, and mechanical advantage and velocity ratio, with worked examples.
