Scientific American, Vol. 42, No. 10 (1880)
Scientific American, volume 42, number 10, published in 1880, is a weekly American periodical of engineering and invention news that carried wood-engraved illustrations of new mechanical devices for a general technical readership. The pictures here show a circular saw mill, a vertical steam engine, a rotary saw-tooth tool and a carpenter's marking gauge, drawn in fine black line with labelled figure numbers and cross-hatched metal shading that a designer could borrow for technical diagrams and vintage industrial graphics.
