ABSTRACT:
The drive system includes a drive pulley operably connected to a prime mover for selective rotation in opposite directions, a driven pulley, an endless belt trained about the drive and driven pulleys, an arm having a first end rotatably supporting the driven pulley and a second end mounted for pivotal movement of the arm and the driven pulley, a drive wheel, such as a sprocket, mounted on the first end of the arm for common rotation with the driven pulley, a rotatably mounted driven wheel, such as a sprocket, and an endless flexible member, such as a chain, trained about the drive and driven wheels for rotating the driven wheel in response to rotation of the drive pulley, whereby the resultant force applied on the drive wheel by the flexible drive member, when the drive pulley is rotated in either direction, is in a direction tending to pivot the arm and the driven pulley about the arm pivot axis in a direction for applying tension on the slack side of the belt.
