ABSTRACT:
A tensioning device for flexible drive elements such as chains or belts comprises a pair of opposing guide blocks and a connecting and tensioning assembly for spacing the guide blocks from each other. The guide blocks are slotted to receive the runs of the drive element. The assembly includes a pair of retainers which are connected together by rods and fasteners. Springs are positioned between each guide block and its respective retainer to bias the blocks toward each other. Each retainer is pivotally attached to its respective guide block to permit oscillating or pivoting movement while the drive element travels through the guide slots. The rods and fasteners permit adjustment of the spacing between the guide blocks to adjust the tension on the drive element.
