Scientific American, Vol. 30, No. 3 (1874)
Scientific American volume 30, number 3, published in New York in 1874, is a weekly periodical for American readers interested in mechanics, inventions and industry. Its pages carry technical line engravings of patent mechanisms, tramway vehicles and furnace plans, drawn in precise outline with lettered reference figures. A designer could take from them the clean diagrammatic style of nineteenth-century engineering drawing, with labelled parts, sectional views and simple hatching.
