Notices of Mining Machinery and various mechanical appliances in use chiefly in the Pacific States and Territories, for mining, raising, and working ores, etc
A technical survey of mining machinery by William Phipps Blake, issued in 1871 by C. C. Chatfield & Co. for engineers and mill operators working ores in the Pacific States and Territories. The plates are wood-engraved line diagrams of jigs, rock breakers, crushing rollers and ore-washing tubs, shown in section and elevation with key letters and ruled baselines, useful for hairline mechanical linework, cutaway conventions and annotated machine parts.
