Abstract: A mechanism for continuously transporting a variety of receptacles with predetermined adjacent spacing. The mechanism uses a first and a second chain driven by a common shaft around identical closed circuits, but vertically offset from one other. These closed circuits have opposed linear sides joined by identical opposed semicircular shaped ends, directed by grooves on opposite sides of a guide block. A vertical support, attached between the first and second chains, traverses the outside of the block. A third chain traverses a second circuit, which is centered and directly below the second chain, directed by a groove in the uppermost side of a horizontal frame positioned under the guide block. This second circuit is identical to the others in shape however it has a greater distance between the semicircular ends. Levers, each equal in length to one half of the third chain circuit elongation, are pivotably attached to the vertical support and to a plate.

Abstract: A conveyor platform is formed from a series of pivotally interconnected segments. Each segment has a stop block, and each stop block has two strike faces. Each strike face abuts against an opposing strike face on adjacent stop blocks when the platform is in a planar position. The stop blocks cannot be compressed, so, when the platform is carrying a load, the stop blocks prevent the platform from sagging. The platform turns as it travels around drive chain sprockets on the return portion of the cyclical drive chain pattern. When it turns, a gap is created between opposing strike faces on adjacent stop blocks. When adjacent segments of the platform emerge from the turn, the opposing strike faces come rapidly together. A bore extends inwardly from one of the strike faces on each stop block and a resilient urethane plug is mounted in the bore. The plug projects slightly beyond the strike face when the opposing strike face on the adjacent stop block is spaced from the plug-bearing strike face.
