  • Patent number: 5219065
    Abstract: A chain link for a product capturing chain, including a pair of opposed retaining lips for retaining the resilint gripping member.
    Type: Grant
    Filed: July 10, 1992

  • Patent number: 4893709
    Abstract: An article carrying chain includes a plurality of interconnected molded plastic chain link assemblies each having a planar top plate. The chain link assemblies are interconnected so as to permit articulation between adjacent links around orthogonal axes. The potential for wear or breakage between adjacent links is reduced by beveling at least one of the mating edges between the top plates of adjacent links. Product kick-up is avoided by rounding the upper surface of each top plate along its leading and trailing edges. The underside of each link assembly is shaped so as to be engageable by either side of a sprocket tooth to thereby permit the sprocket to drive the chain in either of two directions. A plurality of upper and lower tabs formed along the lower portions of the chain link assemblies function to stabilize the chain relative to a pair of glide rails while permitting free removal of the chain link assemblies from the guide rails.

  • Patent number: 4865183
    Abstract: A sprocket and drive shaft assembly for a wide conveyor belt composed of modules pivotally connected in chain-like fashion and subject to environmentally caused fluctuations in width such as extreme temperatures. The assemlby includes a drive shaft with a polygonal cross section and a plurality of toothed sprockets each having an axial bore which slidingly engages the cross section of the shaft and permits the sprockets to move laterally in response to fluctuations in conveyor width and lateral alignment, as the rotating sprocket assembly drives the conveyor. Restraining devices such as set screws are provided on the drive shaft to prevent the sprockets from undergoing excessive axial movement (toward the ends of the drive shaft) while allowing the sprockets axial freedom to shift in response to lateral belt misalignment and width fluctuation.
