A textbook on mechanical and electrical engineering
A correspondence-course textbook on mechanical and electrical engineering issued by the International Correspondence Schools in Scranton, Pennsylvania, 1898-99, for working tradesmen studying machine design by mail. The plates are line drawings of machine parts — concentric shaft bores, cams, and flywheel sections laid out with centre lines, dimension arrows and formula annotations — alongside pages of set type and a woven cloth binding usable as a texture.
