Scientific American, Vol. 24, No. 5 (1871)
Scientific American, volume 24, number 5, a weekly American periodical of 1871 that printed engineering and mechanical news for inventors, mechanics and general readers. The pictures are plain black-and-white wood engravings of machinery, including a railway car running gear, a tall cylindrical column, a horse-drawn roller and marker, and a friction gearing diagram, each with lettered parts for reference. A designer could take their clear line work, labelled cutaway views and period mechanical detail as reference for technical drawings.
