Scientific American, Vol. 34, No. 25 (1876)
A weekly American periodical of 1876 covering science, invention and mechanical engineering, aimed at inventors, mechanics and general readers. Its pictures are black-and-white wood engravings of machines and apparatus, including a railway car coupling detail, a scroll saw with a treadle base, a pressurised tank apparatus and a sectional view of a shaft running through a bearing, showing clear outlines and labelled parts that a designer could use for mechanical line drawings and period industrial motifs.
