Betterment briefs : a collection of published papers on organized industrial efficiency
Betterment briefs collects Henry William Jacobs's trade papers on shop organization and standardization in railroad repair shops, published by John Wiley in New York in 1909 for mechanical engineers and shop superintendents. Halftone photographs show milling machines, exposed gear trains, worn bronze worm gears and belt-driven spindles, with running heads and figure captions—useful for machine-part silhouettes, gear forms, and grainy industrial texture.
