Mechanical movements, powers and devices
Gardner D. Hiscox's reference compendium of mechanical movements, powers and devices, published by Norman W. Henley in New York in 1911 for engineers, draftsmen, inventors and shop mechanics. Over a thousand small line diagrams show gears, cams, clutches, pumps and governors in section and elevation, with hatched cut surfaces, key letters and motion arrows, useful as technical linework and pattern texture.
