ABSTRACT:
For controlling the tension on the belts of a multiple belt drive, one or more sheaves are journaled on each end of a walking beam, which in turn is pivotally mounted on a spring-biased lever. The total number of sheaves employed corresponds to the number of belts in the multiple belt drive, and the sheaves are spaced apart axially thereof, and the lever is so mounted, that one of the sheaves is in rolling, bearing engagement with each of the belts. The walking beam-to-lever pivotal connection is so located as to cause the sheaves to exert equal, or controlled differential, pressure on all of the belts.
