Abstract

An endless power transmission chain-belt (13) especially adapted for drivingly connecting the pulleys (2 and 3) of a pulley transmission (1) having a chain (10, 12). The chain (10, 12) is an assembly of plurality of interleaved sets of links (16, 18, 20, 22). A pivot means (24) extends through the chain (10, 12) to lace and pivotally interconnect adjacent sets of links (16, 18, 20, 22) to provide an endless chain-belt (13). The sets of links (16, 18, 20, 22) of the chain (10, 12) are held together by the pivot means (24). A plurality of load blocks (14) are connected to the chain-belt (13). The load blocks (14) have at least one projection (15) that extends in a direction towards chain (10, 12). The projection (15) engages adjacent pivot means (24) to secure the load blocks (14) to the chain (10, 24). The load blocks (14) extend substantially across the width of the chain (10, 12). Each load block (14) has lateral edges (26, 28) that are shaped to frictionally engage the pulleys (2 and 3) of a pulley transmission (1).
