Gunther, R; Sander, G

A subsurface coal bunker operating to receive and discharge coal is structured with an assemblage of nested telescopic container members including one stationary member and a plurality of movable members, with the container members being formed in size in a graduated series with each container member being sized to fit into a next larger container member adjacent thereto. The movable members are telescopically extensible and contractible in order to vary the volume of the assemblage and the bunker assembly is provided with a first belt conveyor for feeding material into the assemblage and a second belt conveyor for transporting material therefrom. A reversible drive mechanism, consisting of hydraulic cylinder devices actuating a system of drive chains and pulleys, is mounted on a support frame of the bunker and operates to drive the movable members between the extended and contracted positions.
