The reinforcing throughout consists of Johnsonscorrugated steel bars. COAL HANDLING MACHINERY. Coal is delivered to a 15 by 20 ft. receiving hopper locatedunderneath the receiving track and is carried to the elevator byan automatic loader, which insures the proper amount of coalbeing delivered to each bucket of the ele/ator, The elevator andconveyor, which carries it up and distributes it to the overheadpocket, consists of V shaped buckets mounted on a steel rollerchain and has a capacity of 100 net tons per hour. The power fordriving the elevator is supplied by a 30 h. p. alternating current. A SOLID CONCRETE COALING motor located above the main pocket and connected to the drivingshaft by a leather belt. SAND HANDLING MACHINERY. Wet sand is shoveled into a small receiving hopper located onthe outside wall on a level with the top cf an ordinary gondolacar, and then elevated to the wet sand storage pocket by a cen-trifugal discharge elevator, consisting of a rubber belt withsmall malleable iron buckets. The capacity of the elevator is 10tons per hour. The sand drying room is directly under the wet sand pocket,so that the sand is delivered by gravity lo a steam dryer in thedrying room. After being dried and screened, it is delivered toa sand drum, also located in the same room, from which it isfinally elevated through a four inch pipe to the overhead drysand storage bin by means of compressed air. A small compressor connected by a belt to a 5 h. p. motor, bothof which are located in a separate house on the ground level,suppl
