Calumet and Hecla Mining Companies Drawings Collection, 1871-1970.

http://www.worldcat.org/oclc/759106034

Drawings, 1871-1970, of the Calumet & Hecla Mining Companies. Contains hand sketches, tracings, blueprints and related manuscript items as well as a card index created by the company. Includes more than 80,000 engineering and architectural drawings gathered by the Calumet & Hecla Mining Company during its active life as a copper mining company in Michigan's Keweenaw Peninsula. Much of the machinery was built in-house at Calumet & Hecla and they also had need of maps of both aboveground and underground for the layout of buildings, mine shafts and railroads. For all machinery ordered from other manufacturers, Calumet & Hecla needed drawings of the buildings for this machinery, the foundations for it, and as years went by, alterations and repairs to it that were carried out with the company's capabilities. Occasionally Calumet & Hecla bought machinery, or brought it from other mines and made drawings for future use. In addition, the collection includes significant documentation of non-industrial structures and sites such as company housing, public parks, schools, and libraries, municipal water and sewer systems, and local churches.

655.0 cubic feet; 45 boxes, 320 map drawers.
