Mechanical movements, powers, devices and appliances;
Gardner D. Hiscox's 1903 compendium of mechanical movements, published by N. W. Henley in New York for engineers, draftsmen, inventors and machine shop workers. Nearly a thousand small line diagrams show gears, cams, linkages, valves and presses in section and elevation, hatched for cutaway parts and keyed with italic letters; useful for engineering-drawing motifs, hatch textures and diagram lettering.
