Abstract
The inventive device includes a support shaft having a longitudinal axis with a locus that does not change, including when the shaft is positionally rotated about such axis. A collar is mounted on the shaft for supporting an idler pulley having an axis of rotation. An indexing plate is also mounted on the shaft for maintaining a selected position of the collar, the angular position of which is adjustable. An indexing surface is in position-affecting relationship to the collar and defines a plane oriented at an angle with respect to the shaft axis. This angle is adjustable for selecting the position of the collar. The device permits the locus of the axis of rotation of the idler pulley to be selected to maintain alignment of a belt with a driving pulley, thereby preventing such belt from becoming disengaged from the driving pulley.
