  • Patent number: 6415904
    Abstract: An apparatus for conveying conveyable material. The apparatus includes a plurality of cars joined together by a plurality of spacers. The spacers couple the cars a fixed distance apart to form a shuttle. The shuttle is guided along a track between a first position and a second position. In the first position, the shuttle is aligned with a first group of supports. The shuttle in the first position receives conveyable material from the supports. The shuttle in the second position is aligned with a second group of supports. The shuttle disposes the conveyable material from each of the cars carrying the conveyable material to the second group of supports. A drive means repeatedly drives the shuttle between the first position and the second position. The cars remain the fixed distance apart during the driving between the first position and the second position.

  • Patent number: 5253398
    Abstract: A hydraulically-driven deburring shear assembly used to remove dross from the edges of a slab of steel that has been torch cut. The assembly comprises a table assembly, a pair of arms, and a knife assembly. Each arm is adapted to alternately act as a pinch roll and a pusher arm to effect the consecutive deburring of opposed edges of a slab of steel, as follows. After the slab of steel is placed on the table, one of the arms is lowered to rest on the slab and apply a downward pressure on the slab, and the other arm is lowered to come into contact with the leading edge of the slab. At the same time, the knife assembly is raised to the level of the table. The other arm then pushes the leading edge of the slab back over the knife assembly to shear the dross from the edge. Both arms are then raised, the knife assembly is lowered, and the slab is traversed in the forward direction.
