Scientific American, Vol. 33, No. 22 (1875)
A weekly American periodical of 1875 aimed at inventors, mechanics and general readers, reporting new machines, patents and engineering practice with engraved diagrams. The pictures show an improved hand and slide lathe in two views, a sectioned furnace or boiler arrangement with brickwork, and a panelled interior doorway with a shelf, drawn in clean black-and-white line engraving that a designer could borrow for technical diagrams, labelled plates or mechanical line art.
