Scientific American, Vol. 5, No. 35 (1850)
Scientific American, volume 5, number 35, from 1850, is a weekly American periodical of mechanical and scientific news for inventors and general readers, printed in New York. Its pictures are wood-engraved mechanical diagrams of an air gun, a saddle pad with its stirrup and girth arrangement, and a machinery clutch on a shaft and pulley. A designer could take from them the crisp hatched linework and labelled cutaway views typical of nineteenth-century technical drawing.
