Scientific American, Vol. 30, No. 6 (1874)
A weekly American periodical of 1874 aimed at inventors, engineers and mechanics, carrying technical news, patent notices and trade advertisements. Its pictures are small black-and-white wood engravings of machines, such as a threshing machine, a combine-style harvester, a rotary cylinder mechanism and a trade-catalogue page of lathes and woodworking tools. A designer can take from them the dense, utilitarian line work of nineteenth-century mechanical drawing, with its hatching, cutaway views and labelled figures.
