Scientific American, Vol. 24, No. 22 (1871)
Scientific American, volume 24, number 22, a weekly American periodical of 1871 that printed technical inventions and mechanical devices for a general readership of inventors, mechanics and manufacturers. The pictures are plain line engravings of machine parts, a belt-shifting fork, a wooden box and a steam heating apparatus, drawn with crisp outlines and hatching that a designer could borrow for diagrammatic or industrial-style graphics.
