FRONTS—Ornamental fronts are fitted to the front supporting frame. These have large doors for access to the front headers and panels above the fire fronts. The fire fronts where furnished have independent frames for fire doors which are bolted on, and ashpit doors fitted with blast catches. The lugs on door frames and on doors are cast solid. The faces of doors and of frames are planed and the lugs milled. The doors and frames are placed in their final relative position, clamped, and the holes for hinge pins drilled while thus held. A perfect alignment of door and frame is thus assured and the method is representative of the care taken in small details of manufacture.
The front as a whole is so arranged that any stoker may be applied with but slight modification wherever boilers are set with sufficient furnace height.
In the vertical header boilers large wrought-iron doors, which give access to the rear headers, are attached to the rear supporting frame. [Pg 54]
