Abstract
An apparatus for charging chambers of a coke oven has a horizontal screw conveyor with a downwardly open outlet and a telescopic charging chute below the outlet having an upper intake funnel and a telescopic lower part alignable with the charging ports by horizontal and longitudinal displacement. A support frame carries the intake funnel and a lifter for vertically displacing the telescopic lower part. A traveling frame in which the support frame moves transversely can also move longitudinally on rails. A seal on a top side of the support frame surrounds the intake funnel of the telescopic charging chute, works together with a horizontal lower flange surface on the outlet of the horizontal screw conveyor, and permits horizontal movement of the intake funnel relative to the outlet of the horizontal screw conveyor.
