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. The plate, also pivotably attached to the third chain, traverses the outside of the guide block to provide stability for the third chain. Vertically oriented pins, integral with spacer elements, provide the levers pivotable attachments. These spacer elements have uniformly spaced indentations sized for the receptacles. The spacer elements are parallel to the chains, face directly outward from the guide block along the linear portions of the circuit, and release the receptacles at the curved circuit ends.
