  • Patent number: 4067428
    Abstract: An improved multiple-roller conveyor having a support for objects located between adjacent shafts. The support snaps onto the shafts between rollers mounted upon the shafts. The support extends between the shafts and extends upwardly less than the rollers mounted on the shafts. Small objects being conveyed along the tops of the rollers may fall over due to the spaces between the tops of adjacent rollers. The support prevents the bottoms of the objects from dipping too much into the spaces between the rollers, and thereby keeps the objects from falling over.

  • Patent number: 4053039
    Abstract: A support for a conveyor shaft having a plurality of rollers mounted thereon. The support snaps onto the shaft between two of the rollers. The support projects downwardly below the rollers, and is spaced above a support surface. Excessive weight on the shaft will cause the shaft to bow or bend downwardly and the support will then engage the support surface to resist further bowing of the shaft. The support extends perpendicularly to the shaft to support similarly a plurality of shafts.
