The Street railway journal . hich may be inserted through holes provided in the boilerroom floor between the boiler fronts, as indicated in theboiler-room longitudinal section; the down spout is swung overin line with this chute, and the coal permitted to pass throughand enter the conveyor in the ash room below, whence it is ele-vated. It has been demonstrated that spontaneous combustion amount of coal delivered from the receiving hopper throughthe crusher, and in turn into the conveyors, is regulated. Thecross-line conveyor is operated from the coal crusher mechan-ism. The conveyor driving mechanism for operating the mainline McCaslin conveyor is of the self-contained, direct-con-nected type, located in the loop at the point indicated on thedrawing. The starting and speed regulating controller, alsoprovided for this motor, enables the speed of the conveyor sys-tem to be changed, and will operate at from 35 lineal ft. toabout 45 lineal ft. per minute. The coal-crusher mechanism being installed at this plant is of. SECTION A-A DETAILS OF THE SPECIAL INTAKE CONSTRUCTION UPON THE RIVER FRONT TO PROTECT THE CONDENSER CIRCULATION SUPPLY PIPES AND ENSURE AN UNINTERRUPTED SUPPLY in coal piles always occurs at the near the center,namely, at the point of greatest pressure; in the case of abunker of the shape used here it usually occurs near the en-trance to the down spout. In this way, by drawing off a fewtons from the lower part of the bunker, when heating occurs,combustion may be easily and successfully prevented; this is avaluable provision, as it has always been found that pouringwater on the coal in such a case only increases the liability ofheating. The capacity of the coal crushing and coal and ash conveyingequipment being installed will be from 40 tons to 45 tons perhour. The coal crusher mechanism is operated by GeneralElectric three-phase variable-speed induction motor, providedwith a starting and speed-regulating controller, by which the the well-know
