John Buddle mining engineer. He succeeded his father as manager at Wallsend Colliery in 1806, though his work was not limited to just the local colliery. Buddle was involved with the introduction of the miners safety lamp invented by Humphry Davy being involved in the earliest discussions with Davy in August 1815 and providing "fire-damp" samples for experiments in Davy's London Laboratory. The moment when Buddle tested the new Davy safety lamp for the first time, for real, in Northeast England, is recorded by him in a report to the Select Committee on Accidents in Mines on 4 September 1835 "I first
Safety lamp forming a cage. All except the very earliest Davy lamps have a double layer at the top of the cage. Rising hot gases are cooled by the gauze, the metal conducting the heat away and being itself cooled by the incoming air. There is no restriction on the air entering the lamp and so if firedamp is entrained it will burn within the lamp itself. Indeed, the lamp burns brighter in dangerous atmospheres thus acting as a warning to miners of rising firedamp levels. The Clanny configuration uses a short glass section around the flame with a gauze cylinder above
