Scientific American, Vol. 24, No. 16 (1871)
Scientific American volume 24, number 16 from 1871 is a weekly American periodical of mechanical and scientific news, published in New York for engineers, inventors and tradesmen. Its wood-engraved figures show mechanical devices in plain outline: a shaft coupling with numbered parts, a geared hoisting winch with a wire rope drum, an octagonal wooden tub, and a serrated clamping tool with a long handle. A designer might take the crisp hatched shading and labelled cutaway views as models for technical line work.
