Scientific American, Vol. 34, No. 22 (1876)
Scientific American, volume 34, number 22, is a weekly American periodical from 1876 that printed engineering and mechanical news for a general technical readership. Its pictures are wood-engraved mechanical drawings of governors, a morgan grain-sowing machine, and a winding apparatus, drawn in clean outline with hatched shading and labelled parts. A designer could take from them the precise line work and the way machine parts are isolated against plain grounds.
