Miner’s Safety Lamp

Usage conditions apply
Description (Brief)
This safety lamp model is an Ashworth-Hepplewhite-Gray lamp. The lamp is a “test lamp” used to measure the amount of methane in the air. The tubes that run vertically direct air to the flame at the base, which will then produce a colored “cap” in the presence of methane. The majority of Ashworth-Hepplewhite-Gray lamps were produced by John Davis & Son of Derby, Leicestershire, U.K., during the late 19th and early 20th century.
