To repair the brickwork of tie- chambers of coke ovens without stopping light compared with nil, and just enough is added tosaturate the porous material in the lamp. The flamecan be regulate,! by a screw at the bottom of theapparatus, and extinguished at will. The great lhe lam], is that it can be lighted without openingit : this is done by a little friction machine in the lampfor Bring caps, which are attache I to a Btripof paper andinserted in a coil.
