Abstract
A chain-belt adapted for use in a pulley drive system and comprising a plurality of connected ranks or sets of interleaved links having generally trapezoidal load blocks between adjacent pivot means which join the adjacent ranks or sets of links together to permit articulation of the chain belt. The load blocks are of generally laminated construction of a plurality of plates and resilient means are located between adjacent plates in at least some of the load blocks. Preferably an elastomeric material such as rubber is chosen as the resilient means and each load block incorporates the resilient means. The structure is effective to reduce noise generated upon engagement and disengagement of the chain-belt with the pulley flanges when compared to a chain-belt of connected ranks of links and with laminated load blocks therein but without the resilient means.
