ABSTRACT:
The present disclosure sets out a belt tightening apparatus conformed by modifying a caulking gum fixture to include end fittings which are alternatively received in adjustment slots or which may be abutted against pulley wheels to tighten a pulley belt. More specifically a ratchet advancing mechanism useful with caulking cartridges is modified to include a transverse bar extending through the cartridge seat and projecting beyond the periphery thereof a free end of the ratcheting box be provided with either a cantelevered end fitting or with an end fitting adapted to receive a square drive. The other end of the ratchet handle may be similarly provided with a square fitting and the respective square fittings may be attached to arcuate brackets adapted for receipt in the groove of a pulley wheel. Thus the ratcheting action of a caulking gun may be used to advantage in tensioning pulley belts, the self-locking features thereof providing the further advantage of unattended operation.
