| The first safety lamp made by William Reid Clanny used a pair of bellows to pump air through water to a candle burning in a metal case with a glass window. |
| Clanny abandoned his pumps and candles and developed a safety lamp which combined features of both the Davy and Geordie. |
| The Clanny gives more light than the Davy and can be carried more easily in a draught. |
| So far this is just a Clanny, but in the Mueseler a metal chimney supported on an internal gauze shelf conducts the combustion products to the top of the lamp. |
| Like a Clanny, and the Davy before it, it acts as an indicator of firedamp, burning more brightly in its presence. |
| The Clanny configuration uses a short glass section around the flame with a gauze cylinder above it. |
