Model "A" Wheat Lamp

Description
This is a Wheat Type “A” electric cap lamp manufactured by the Koehler Manufacturing Company of Marlborough, Massachusetts in 1917. Grant Wheat designed an electric cap lamp (often called the Wheat lamp) that was manufactured by the Koehler Manufacturing Company, who has continued to manufacture Wheat brand lamps into the 21st century. The Wheat lamp consists of a battery encased in a locking metal case worn on the miner’s belt. A flexible cord traveled to the cap lamp, which would be worn on the miner’s helmet. This lamp belonged to Grant Wheat’s personal collection that was donated to the museum in 1962.
