. The Street railway journal . e river. Atraveling carriage is mounted on the crane, which extendsout 42 ft. from the side of the building. The coal can be bunker with a capacity of 95 tons. An opening in the roof,normally covered with a tight hatch, is provided over eachof the bunkers, which are fed through these openings bythe chutes on the traveling bridge. The bunkers are car-ried by steel columns in the fronts of the boiler settingsand by the roof trusses. A vertical chute controlled at thetop by a gate operated from the firing room floor feedscoal from each bunker to the charging hopper of the stokerimmediately under it. The ashes from each stoker are discharged into a tightchamber directly under the front of the boiler setting. Achute also leads into this chamber from back of the furnacebridge, which is provided for conducting into the ashchamber the soot and fine ashes that collect back of thebridge. Two 24-in. gage tracks are laid the length of thefloor of the basement under the firing- floor in the boiler. CROSS-SECTION OF THE NORFOLK POWER STATION OF THE NORFOLK & PORTSMOUTH TRACTION COMPANY elevated from the cars on the trestle, from the storage bin,or from vessels moored along the dock on which the binstands by a i-ton clam-shell bucket swung by a hoistingcable from the traveling carriage. The clam-shell bucket dumps into a hopper at the innerend of the crane. A chute leads from this hopper to thecoal crusher immediately under it, the crusher dischargingon a belt conveyor inclined upward toward the top of thetraveling bridge and extending to the middle of the latter;the crusher may be by-psssed and coal discharged from thehopper directly to the conveyor. Gates are arranged atthe end of the conveyor so the latter will discharge at themiddle of the bridge into either or both of two inclinedchutes leading down to openings in the roof of the boilerroom. These chutes are each fitted at the lower end withan undercut gate controlled from the operators cab. Coa
