    Patent number: 4441603
    Abstract: Apparatus for extracting bulk material and transferring it to a discharge device is disclosed. The apparatus comprises a housing with one or more cylindrical vertical sleeves receiving worms for feeding the bulk material to the discharge device. The worm is continued downwardly from the sleeves by a spiral helical flight rotatable with the worm. A conduit is defined between a vertical wall bounding the spiral helical flight outwardly and a central hub around which the spiral helical hub is coiled. A ledge connects the upper and lower parts of the extraction device formed by the worm and the spiral helical flight, and the spiral helical flight runs smoothly and uninterruptedly into the worm.
