Mechanical drawing for trade schools
A mechanical drawing textbook by Charles Carley Leeds, published by D. Van Nostrand in New York in 1911 for trade school students learning shop drafting. Plates are line drawings of machine parts — pulleys, flanges, stepped shafts, keyways — with center lines, dashed hidden edges, arrowed dimension strings and fractional inch figures on tan paper, useful as technical-diagram texture or measured ornament.
