ABSTRACT:
A single tensioner is used to tension a double belt. A spring biased, swinging primary arm has a secondary arm freely pivoted to the end thereof. One idler pulley on the secondary arm pushes on a run of one of the belts, while another idler pulley pulls on a run of the second belt. Thus, the two idler pulleys can tension both belts simultaneously, and the free pivoting of the secondary arm relative to the primary arm as the primary arm swings compensates for differential belt stretch.
