Abstract: The invention provides a conveying apparatus including an upstream conveyor, a downstream conveyor oriented perpendicularly to the upstream conveyor to form a butt turn, and a mechanism for transferring conveyed articles from the upstream conveyor to the downstream conveyor. The transfer mechanism includes guide rails that provide a corner to change the direction of travel of the conveyed articles and a transfer assist conveyor for supporting the articles as they travel between the upstream and downstream conveyors. The transfer assist conveyor runs alongside the upstream conveyor and has a cantilevered section that extends over the sprocket location of the downstream conveyor to perform the function of a prior art static transfer plate.

Abstract: A conveyor chain assembly including a multiplicity of rows of chain modules, each module includes a plurality of link ends with coaxially aligned openings. A chain pin passes through the coaxially aligned openings of adjacent modules. On the opposite ends of each module is a plug socket which is adapted to house a plug. The plug includes a shaft and an arm. The arm is moveable when the shaft is mounted in the socket between a first position in which the arm restricts axial movement of the chain pin and a second position in which the arm does not restrict axial movement of the chain pin.
