The carbidebeing placed in movable cups C. These cups are fitted to a frame work and rest on a rack attached to the genera-tor and tripped automatically as required by means of a tripping bar attached to tliegasometer, the cups when tripped descending into the generator B and turningup behind the partition as in the illustration.

The gas rises thoroughly washed and perfectly cool through the water behind thepartition and thence into the gasometer A which is of sufficient capacity to storethe gas produced from one cup of carbide. A duplicate set of cups is supplied and when one set has been submerged theycan be easily withdrawn and dried, the duplicate set being charged and attached intheir place.
