Scientific American, Vol. 86, No. 4 (January 1902)
An issue of the weekly technical magazine Scientific American, published by Munn & Co. in New York in January 1902 for inventors, engineers and general readers following patents and industry. The plates are wood-engraved and pen-line depictions of machinery — a stationary gasoline engine, a belt-driven lathe, a governor mechanism, a sectioned lamp with wiring — giving designers isolated apparatus on blank ground, cutaway sections and mechanical diagrams.
