  • Vacuum metering drum assembly
    Patent number: 4890960
    Abstract: A metering drum assembly for the rotation of can-shaped objects over a surface from a first to second location. The drum device employs an inner, hollow, non-rotating, cylindrical member and an outer, hollow, rotating, cylindrical member, each cylindrical member being oriented about the same longitudinal axis. A vacuum is drawn within the inner, hollow, non-rotating, cylindrical member pulling air through the perforated surface of the outer, hollow, rotating, cylindrical member only across a defined segment of orientation.

  • Article transport elevator
    Patent number: 4673080
    Abstract: Apparatus for transporting articles, such as cylindrical containers, between differing elevations by initially moving the articles on an upper surface of a first plenum by air pressure. The articles are then transferred to a moving belt supported on an upper surface of a second plenum and held on said belt by vacuum. A transfer means is provided at the overlap of the first and second plenums to enhance the transfer of the articles between plenum sections.

  • Transfer mechanism
    Patent number: 4658947
    Abstract: A device for removing or sending an article from a conveyor of a transport system to and from work stations located therealong comprising platforms capable of being raised or lowered so that an article being carried by the conveyor can be taken out of physical contact with the conveyor at various work station locations. Once the article has been raised out of contact with the central conveyor, a closed loop belt driven by a fluid actuated cylinder causes the article to be conveyed onto or away from the central conveyor.
