Abstract

Apparatus for applying an optimum tensioning force to an endless belt or the like, including a first pivot axis, a belt engaging pulley eccentrically supported for rotation about a second axis displaced from the first pivot axis, a torsional biasing spring for urging the belt-engaging pulley into belt-tensioning engagement with the belt and for automatically maintaining the tension force applied to belt. The torsion spring is disposed about the first axis within the eccentric pulley, which includes further springs for releaseably gripping the pivot to adjustably limit the applied tensioning force in a first direction and in a second direction, whereby the tension in the belt is optimally maintained throughout the engine operating temperature cycle.
