Description

Antique Wolfs "Permissable" miners safety lamp. This early aluminum lamp is in as used condition but is a very rare collectible lamp because of its Made in USA and intact brass plaques (please see photos). The brass plaque on the top says "Mine Safety Appliance Co Pittsburgh US". The brass plaque on the bottom side says "Permissible Miners Flame Safety Lamp Co. of America USA Pat #20". It has a U.S. Bureau of Mines Seal with an eagle. The glass says Wolf Made in USA. The upper outer shield has dents and missing flare pieces but this is a collector lamp with its provenance of the brass plaque.
Lamp 10.5" x 3.5", with hook 14.5"
Wolfs "Permissable" miners safety lamps were designed to not only give an underground miner light to work but not to ignite gas in the mine. The U.S. Bureau of Mines certified these lamps as "Permissible" for underground use. The height of the flames showed when there was too much methane to be safely underground and if the flame went out these was too little oxygen for it to be safe underground. They were used around the early 1900s in underground mines in the U. S. and Europe.
This is from a collection of Antique Mining Artifacts from an Arizona Estate. it was collected over the past 50 years and represents the tools of the underground miners. It is as found and is as used in the mines.
