Abstract
The driving tension of a drive belt is maintained by axial force components applied to a pair of adjustable diameter pulleys about which the drive belt is entrained. A spring force is divided into such force components under control of relative torque loadings applied to the pulleys through drive shafts thereby also establishing a drive ratio that is automatically varied by relative adjustment of the pulley diameters.
