Scientific American, Vol. 24, No. 26 (June 1871)
A weekly issue of Scientific American from June 1871, published in New York for inventors, patent holders, and working mechanics. The thirteen cuts are wood engravings of machinery — stationary steam engines, boiler settings in section, treadle and flywheel presses, sheet-metal shears on trestle frames — drawn in stark black silhouette with ruled hatching, useful as industrial spot art and technical profile shapes.
