ABSTRACT:
Chain driven expandable powered conveyors utilizing lazy tong structures. A first embodiment of such conveyors employs elongated rollers which are connected to sprockets driven by one or more drive chains. The chains follow a tortuous path through the conveyor structure allowing efficient and effective transmission of power from a power source to the sprockets and elongated rollers regardless of the extent to which the conveyor is expanded or contracted. A second embodiment, which also employs elongated rollers, includes sprockets powered by a chain that in turn apply power to elongated rollers using drive belts. This embodiment avoids exposure of drive chain at the surface of the conveyor, allows accumulation of product on the conveyor and features other advantages. A third embodiment employs skate wheels rather than elongated rollers. A drive chain applies power to drive sprockets on the surface of the conveyor which propel product on the conveyor.
