Wheat Electric Cap Lamp
notes: label: Description
content: The Koehler Manufacturing Company produced this battery-powered cap lamp during the first half of the 20th century. Inventor Grant Wheat designed this lamp, leading to this type of lamp being called a “Wheat Lamp.” The battery is encased in a self-locking black plastic case worn on the miner’s belt. A flexible cord traveled from the battery to the lamp, which was worn on a mining cap. The metal seal between the case and the lid is stamped “WHEAT LAMP / KOEHLER MG. CO / MARLBORO, MASS."
