Inventors' & mechanics' scientific manual and patent law complete
A combined patent-law guide and mechanics' handbook issued by the Chicago firm Peck & Miatt in 1871 for inventors, machinists and working tradesmen seeking to file claims. Small wood-engraved vignettes show a workman filing a boiler, a miner with pick and pail, a seated allegorical figure with shield beside sailing ships, and clasped ledgers with inkwell — usable as trade emblems and chapter marks.
