- General Electric Company Catalog, "Electric Mine Locomotives," 1904 - At the turn of the 20th century, General Electric manufactured several models of electric locomotives for use in underground mines -- where smoke and soot from steam locomotives was dangerous and impractical. These small mine locomotives collected electricity from overhead lines or third rails that ran alongside the track. GE also built larger electric locomotives for use with conventional railcars aboveground.

- Iron Ore Briquette from Edison Mines, New Jersey, 1899-1900 - During the 1890s, Thomas Edison launched a New Jersey mining operation to address an iron ore shortage. He designed rock-crushing technology and an electromagnetic ore separator to extract low-grade ore from crushed boulders. The final product -- a briquette made of powdered iron ore -- didn't do well commercially, especially after high-grade ore was discovered around Lake Superior. In 1899, Edison left the industry.

- Patent Model of Miners' Lamp, 1876 - From 1790 to 1880, the U.S. Patent Office required applicants to submit a miniature model along with diagrams and written descriptions detailing the operation of their invention. Patent models could be no larger than 12" by 12" by 12". Though they were usually not operational, these models helped explain an inventor's idea and protect it from competitors.

- Prospector's Claim Stake, Used near Battle Lake, Wyoming, 1880-1910 - This prospector's cedar stake was used on a mining claim near a "Lake Edison" in Wyoming. This is the site where Thomas Edison allegedly conceived the idea for the incandescent lamp. The donor retrieved the stake several decades after Edison's encampment, noting that sand-laden winds blowing from the West had eroded only one side of the stake.
