The coal handlingdevice indicated on the cross section of the power house was se-lected as combining the advantage of small first investment with theability to reduce the coal handling cost. This apparatus has not yetbeen installed bin the tact that at present the coal and ashes areeach handled at least twice only emphasizes the importance of aninvestment in this part of the plant. The apparatus shown consists of a traveling bin carried upon anelevator leg which rests directly upon and travels along a track par-allel to (be boiler room wall. At frequent intervals along this wall.
