Appletons' cyclopædia of technical drawing
A reference volume on mechanical and technical drawing edited by William E. Worthen, published by Appleton in New York in 1896 for draughtsmen, engineers, and students of industrial drafting. The plates are line engravings of machine parts, gear teeth, masonry sections, and building details, rendered in hatching, dotted construction lines, and letter keys on toned paper, useful for diagram textures, sectional hatch patterns, and geometric line motifs.
