Coal awl Ash Conveyor.—The arrangement of the coal andash conveying machinery is clearly shown in the longitudinalrtional view through the boiler room. The coal isdelivered directly from hopper cars to a hopper just abovethe steam-driven coal crusher, and after passing through thecrusher is conveyed to overhead storage hoppers by a C. & Company conveyor, which has a capacity of 50 tonsof coal per hour. Each boiler has a storage bin of 32 tonsi apacity. The conveyor also carries the ashes from the ash pits to a Pro \h:lr. 1905.
