Cyclopedia of textile work;
A multi-volume technical reference on textile manufacturing issued in 1907 by the American School of Correspondence in Chicago for correspondence students training as mill hands, loom fixers, and overseers. The plates are line diagrams of loom and card mechanisms drawn in profile and section, signed C. C. Hedrick, with hatched gears and rollers, dashed motion paths, and single-letter part labels floating in open cream ground.
