. Railway mechanical engineer . Driving Mechanism of the Duprex Locomotive Stoker Showing theVance for Distributing the Coal to the Vertical Screws ings are bolted to the top. At the bottom are bearings forthe right and left elevator driving shafts. Secured to thefront on a pivot inside the hopper, and dividing the coalcoming through the front trough opening, is a dividing ribwhich can be operated through an opening in the cab turning this rib to the left or right the supply of coalto either side may be controlled. There are two elevators raising the coal to the distribu-. Arrangement of the Duplex Stoker as Applied to a Locomotive reverse shaft. The flexible connection consists of a sleeveand a shaft with universal joints. The square shaft fitsloosely into the sleeve, thus furnishing the flexibility in theconveyor shaft made necessary by the movement between theengine and tender. The crusher is at the front end of theopening in the tender deck, and consists of a heavy platewith projections, set in a slide in the trough. The smallersizes of coal are carried through without crushing or break-ing, but the larger lumps are forced against the crusher plateby the conveyor screws and are broken to the proper size for tors, one on each side of the firedoor. The elevator drivingshafts from a bearing in the bottom of the transferhopper through the top of the elevator casing and the bottom of the shaft is a gear which meshes with thevertical teeth of the rack which drives the shaft. The ele-vator drive and reverse mechanism is on the same princ
