ABSTRACT:
Rubberized V-belts used in early friction drives suffered from excessive losses and short wear life. Chains composed of links and pins used in later drives generate excessive noise and develop maldistribution of stress among the several links. The present invention overcomes these shortcomings by providing a belt having a cable along each edge and spacers for holding the two cables apart. The cables form the "rails of a ladder". The spacers form the "rungs"--but are much closer together. The cables carry the circumferential load. The spacers carry the axial load developed by the sheaves on the cables.
