SAND DRYING PLANT OF THE CINCINNATI TRACTIONCOMPANY The Cincinnati Traction Company has a very completemechanical system for drying and distributing sand. Thegreat number of hills in Cincinnati and the numeroussteep grades ranging up to 13 per cent require the use ofabout 10,000 tons of sand each year. Sand is dried in acentral plant at the Brighton car house and distributed toother car houses in a tank car, which handles the sand en-tirely by air pressure. This car also delivers sand to linecars, which place it on the tracks. DRYING PLANT The Brighton car house is built on a side hill, and thesand-drying plant is installed in the basement. Sand is. Pneumatic Sand-Distributing Car delivered in wagons which drive onto the car house floorand dump their loads through traps into the basement. Aleather conveyor belt carries the sand from the dumpingpiles to the drier. This belt is about 40 ft. long and travelsat a speed of approximately 3 ft. per second. At the pres-ent time the sand is screened and thrown on the belt byhand, but the company proposes shortly to install an 1-beam runway with a traveling grab bucket which it isthought will considerably reduce the labor required inhandling wet sand. From the upper end of the belt the wet sand falls intothe feeding hopper of the drying drum. This drum is 3 in. in diameter and 20 ft. long. It is made of boilerplates heavily riveted. Within the drum are baffles, whichserve to distribute the sand and pass it through from endto end. The drum revolves continuously on roller bearingsand is driven by a 12-hp electric motor, which also operatesthe two conveyor be
