Scientific American, Vol. 33, No. 26 (1875)
Scientific American, volume 33, number 26, a weekly American periodical of 1875 that reported on inventions, engineering and industry for a general technical readership. Its pages carry engraved machine drawings and apparatus diagrams, including a double-headed planing or moulding machine, a lettered electrical experiment on a table, a railway danger-signal device with a pendulum and rotating arms, and a multi-tiered spinning frame with bobbins. A designer might take the dense crosshatched wood-and-iron engraving style, the labelled figure keys and the clean mechanical linework of the period.
