  • Patent number: 4738347
    Abstract: The operating characteristics of a diverter having a driven article conveying surface of parallel tubes on which article diverting shoes are caused to move across progressively because of contract between a depending drive pin on each shoe and a laterally inclined rail beneath the conveying surface by changing the shape of the rail contacting roller on the pin so that a downward force vector is created tending to hold the shoe down. Also, the shoe is supported on three rollers instead of two to prevent the tendency of the shoe to pivot about one tube due to article resistance to lateral movement. The design of the openings in the shoe through which the tubes pass are such that the shoe will not become bound between two tubes which are not entirely straight.
