Abstract: A charging machine for charging a glass melting tank furnace includes a reciprocatable charging table above which a hopper is provided for the batch, at the rear side of which at least one movable scraper is provided which seals the slot between the rear wall of the batch hopper and the top surface of the loading table. In order to eliminate the wear on the lower edge of the movable scraper and the surface of the charging table which comes into engagement with the movable scraper, the movable scraper is connected to stroke elements for lifting and lowering, whose stroke is controlled in dependency on the movements of the loading table in such a manner that the movable scraper is lifted during the forward movement of the charging table and is lowered during the return movement of the charging table. In this charging machine, wear occurs only during the table return movement, but not during the table forward movement, so that the wear is cut in half, thus doubling the service life of the machine.
