The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. [1] It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines , to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp .
Sir Humphry Davy, 1st Baronet, FRS, MRIA, FGS (17 December 1778 – 29 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp.
Thomas Harris (d. 1824) invented the gas discharge valve, the first such device for emptying a lighter-than-air balloon of gas. He died when the cord attached to the gas discharge valve in his balloon tightened as it was deflated, releasing more gas than intended and crashing the balloon. [6]
A Davy lamp. In the Davy lamp a standard oil lamp is surrounded by fine wire mesh or gauze, the top being closed by a double layer of gauze. If firedamp is drawn into the flame it will burn more brightly and if the proportions are correct may even detonate. The flame on reaching the gauze fails to pass through and so the mine atmosphere is not ...

1813 Dr William Reid Clanny Exhibited The Clanny Lamp 1815 Humphry Davy Exhibited The Davy Lamp 1815 George Stephenson Exhibited his Lamp The Davey Safety Lamp was made in London by Humphry Davy. George Stephenson invented a similar lamp but Davys invention was safer due to it having a fine wire gauze that surrounded the flame. This enabled the ...
Clanny won medals in 1816–17 for his invention from the Royal Society of Arts. His lamp and other improvements were ultimately recognised by his contemporaries, including northern coal owners who presented him with a purse of gold together with a silver salver at the Athenæum, Sunderland, on 3 February 1848.
