An introduction to machine sketching and drawing for industrial and technical schools
A 1917 mechanical drawing textbook published in Toronto by Copp, Clark for students in industrial and technical schools. The plates are line drawings of machine parts — bearing caps, shafts, flange couplings, bolts and brackets — shown in plan, elevation and sectional view with hatched cutaways, centre lines and inch dimensions, useful as clean geometric linework and measured-diagram vocabulary.
