Abstract

Link-type chain assemblies are disclosed comprising alternating, laterally spaced pairs of inner and outer link plates having overlapping ends pivotally interconnected by rollers between the inner link plates at the overlapping ends. Mounting flanges extend axially outwardly from each of the inner and outer link plates, and plate members are mounted on the mounting plates to maintain the roller axes generally coplanar and to preclude pivotal displacement of adjacent pairs of inner and outer link plates about the roller axes in at least one direction. In one chain assembly, the plate members mounted on the mounting flanges span adjacent pairs of inner and outer link plates to preclude pivotal displacement of the spanned pair of link plates in opposite directions about the roller axis therebetween. In another chain assembly, individual plate members are mounted on the mounting flanges of adjacent ones of the inner and outer link plates and have adjacent planar surfaces which engage to preclude pivotal displacement of the adjacent pair of inner and outer link plates in just one direction.
