The engineer's sketch-book of mechanical movements, devices, appliances, contrivances and details employed in the design and construction of machinery for every purpose;
A working reference of mechanical movements compiled by engineer Thomas Walter Barber and published by Spon & Chamberlain in New York in 1902 for machine designers and draughtsmen. Pages hold grids of small numbered line drawings — sections, plans and elevations of bearings, clamps, valves, pulleys, levers and linkages — hatched and outlined, useful as diagram motifs, technical ornament or icon sets.
