Scientific American, Vol. 34, No. 13 (1876)
A weekly American science and engineering periodical from 1876, printed in New York for a general readership of inventors, mechanics and engineers. Its pages carry patent-style technical line drawings of machine parts, boring and holding fixtures, tools, and electrical apparatus such as Gramme's magneto-electric machine. The cross-hatched sections, labelled lettered parts and clean mechanical perspectives suggest a designer could draw on their precise, diagrammatic linework for technical illustration.
