ABSTRACT:
A rocker joint for a drive chain or a chain-belt comprising a pair of joint members of like cross-section and having front surfaces which rock or roll on one another. The joint members each have a front surface defined by a first radius and a back surface defined by a second and a third radius both progressively smaller than the first radius. A rocker joint pair of members fits into each group of aligned apertures in the interleaved sets of links to join the links and permit articulation of the chain. The link apertures are generally round and have a surface substantially engaged by a back surface of a pivot member.
