Scientific American, Vol. 24, No. 14 (1871)
Scientific American volume 24, number 14, published in New York in 1871, was a weekly American periodical for inventors, engineers and mechanics, presenting new machines and patents with engraved diagrams. Its pictures are precise wood-engraved views of a dovetailing machine, a steam engine, an adjustable screw wrench and a door latch, showing mechanisms from several angles, with cutaway and labelled details a designer could use for mechanical line drawings and technical diagram reference.
