Scientific American, Vol. 40, No. 6 (1879)
A weekly American science and invention periodical from 1879, issued as a volume of Scientific American for a general readership of engineers, mechanics and inventors. Its pictures are mechanical engineering line drawings of machines, a brick kiln cutaway, a funnel-shaped sieve with cross-sections, and a cylindrical stove, all drawn with crisp hatched shading that a designer could borrow for technical diagram styling.
