Mine Illumination: A Historical and Technological Perspective
In 1914, two engineers from the USBM, John Ryan and George Deike, formed the
Mine Safety Appliances Company and began work with Thomas Edison to develop personal electric lamps. By this
time, more efficient tungsten filaments had replaced the older carbon filaments, drastically improving light output
from the bulbs, and Edison was able to design a small-scale, rechargeable battery that could be carried on a miner’s
belt. The Edison electric cap lamp was approved by the USBM in 1915 (Clark and Ilsley
1917). Electric lamps gained acceptance and eventually replaced the older technologies. |
