E is the condenser to which steam is conductedby the copper tube G, leading either from the dome or thetop of the boiler and connected to a dry pipe leading tothe dome. B (Fig. 2) is a steam valve for controllingthe supply of steam to the lubricator; A is the filling plug, LOCOMOTIVE LUBRICATORS. 117 which is removed when the lubricator is filled. Auxiliaryoiler O is provided for each cylinder, independent of thelubricator, and can be used to carry the oil to the cylinderif the feed glass breaks or other defects exist in the lubri-cator which would cause it to become inoperative. Each.
