Scientific American, Vol. 32, No. 17 (1875)
Scientific American volume 32, number 17, published in New York in 1875, was a weekly American periodical for general readers interested in invention, engineering and industry. Its pages carry precise wood-engraved diagrams of machines such as a shingle or stave machine, a saw-tooth dog mechanism shown in Fig. 1 and Fig. 2, and a pump or water-lift apparatus. A designer could draw on their clean outlines, hatched shading and labelled technical drawing conventions.
