ABSTRACT:
A chain constructed of alternating groups of fine blanked articulating links and sets of guide and connecting links. The sets and groups of links are joined by pivot members, journaled in smooth walled openings in the articulating links and press-fit into the openings in the guide and connecting links. The articulating links are of the silent variety with a pair of toes spaced by a crotch with the defining flanks of the toes being adaptable for drivingly contacting the teeth of sprockets. To provide the smooth walled openings in the articulating links, these links are fine blanked as opposed to being conventionally blanked.
