Methods of machine shop work : for apprentices and students in technical and trade schools
A machine shop textbook by Frederick A. Halsey, published by McGraw-Hill in New York in 1914 for apprentices and students in technical and trade schools. Halftone photographs show grinders, lathes, bevel-gear cutters and milling attachments isolated against plain gray backdrops, alongside line drawings that render the same machines as clean outlined sections; useful for machine silhouettes, gear teeth, handwheels and levers.
