Object Details
- Description
- This flame safety lamp is an Ashworth Hepplewhite Gray style lamp manufactured by the American Safety Lamp & Mine Supply Company of Scranton, Pennsylvania during the late 19th or early 20th century. The lamp is a “test lamp” used to test for the presence combustible methane in the mine. The lamp has four tubes that run vertically from the top of the lamp to the glass enclosed flame. The tubes direct the mine’s air to the flame, which will produce a colored “cap” in the presence of methane. The larger the cap, the more methane is present. If the concentration of methane is combustible, the mine will need to be ventilated until safe working conditions are restored.
