  • Patent number: 4284369
    Abstract: The disclosure is directed to a take-up head for a conveyor installation that removes bulk material from the hold of a ship. The take-up head includes a vertical conveying tube carried by a frame, the lower end of the tube defining a take-up aperture. A rotary feeder having a plurality of radially extending spiral veins is rotatably driven to drive material inwardly to the take-up aperture. A holding device, which takes various forms in the several embodiments, projects downward in coaxial relation relative to the feeder to engage the bulk material and resist lateral movement of the take-up head. Anchoring apparatus, which takes the form of a plurality of laterally extending pivotal arms or a laterally extending auxiliary conveyor, is constructed for lowering into engagement with the material to resist rotation of the frame as the feeder rotates. The take-up head is suspended from an on-shore jib that moves the head to various positions within the ship's hold to remove all bulk material.
