The screwgear lias a graduated scale and pointerto show the cut-off, and quite a com-plicated arrangement for controllingthe air piston. There is a band brake,operated by air, on the reversing shaftwhich keeps the gear from going toofast. The engines have a very neatform of furnace door, somewhat likethe accompanying SKETCH OF FURNACE DOOR ON BRITISHLOCOMOTIVE. The door A has a large opening init, closed by the damper-like door firing the main door is notopened, the door B simply being pushedin by the shovel, and it is held open bythe ratchet C, which can be knockedoff again with the shovel, thus closingthe door. Several means of feeding the boilersare used. Some engines have cross- August, 1913.
