Abstract
A dual tension clutch comprising a drive pulley, a driven pulley, and a transmission belt wound around the drive and driven pulleys. Opposite runs of the transmission belt are pressed inwardly by two spring-loaded tension pulleys supported by tension arms pivoted to each other. A triangular frame, as guided by a fixed pin, acts on the tension arms to spread the tension pulleys apart to relax the transmission belt. In the declutching state so established, the tension pulleys are opposed across and equidistant to a line extending through centers of the drive and driven pulleys.
