Scientific American, Vol. 33, No. 1 (July 1875)
A weekly issue of Scientific American from July 1875, published in New York for inventors, mechanics and patent-minded readers reporting new machines and processes. Wood engravings show industrial hardware in three-quarter view or sectional cut — a slotting machine, a geared triple pump, a rail-mounted pile driver, a brick-set steam boiler — dense crosshatching, gear teeth, brickwork and figure labels usable as technical ornament.
