Bessemer Iron Ore Miners
a type of candle holder that was used underground. they were used from the 1880's until about 1910. The carbide lamp came into use around 1910 and was use until the 1930's
The battery lamp then came into use.
At the Penokee mine we were assigned a lamp with a number, mine was 56. These were recharged when we came up from underground and were put out when we came back the next day.
