The bucket towerand the canopy over the pocket are of structural steel and theoperators hoist house on the ground level is of the same ma-terial. The outside covering of these structures is of rust-resisting galvanized .American ingot iron. The single elevating bucket is arranged with a 6-in. roller on.

This positivelyassures the closing of the bucket at all times in its travel, ex-cept when discharging coal at the top. It is carried by a J^ hoisting cable which passes over a 40-in. diameter sheaveat the top and continues downward around the drum of the elec-tric hoist and then to the counterweight which balances the hoist is equipped with Falk patented herringbone steelgears and is direct connected to a 22 horse power, crane type,electric motor. This motor is equipped with a solenoid brakemounted on one end of the motor sliaft to prevent the droppingof the buclvet in case the current is cut off. An automaticbucket hoist control with treadle switches permits the automaticoperation of the elevating process without any attention from theoperator.
