Scientific American, Vol. 54, No. 9 (1886)
This is a weekly American science and engineering magazine, volume 54, number 9, published in New York in 1886 for a general readership of inventors and engineers. Its pictures are black-and-white line engravings of machine tools, railway track gear, electrical transformers and a wood-framed mechanism, with clear labelled parts and captions that a designer could borrow for mechanical diagram styling.
