ABSTRACT:
An adaptor for allowing the pulling of a chain using a hand-held power tool. The adaptor has a gearbox housing a speed reduction gear train. An input shaft projects from the back of the gearbox and an output shaft projects from the front of the gearbox. The input shaft is adapted to be coupled to the output shaft of a hand-held power grinder. A sprocket specially designed to engage an ordinary oval link chain, is mounted on the output shaft. A sprocket housing having a movable cover is attached to the front of the gearbox. The sprocket housing has a movable cover which can be moved between an open and a closed position. The cover acts to maintain the chain in engagement with the sprocket when the chain is mounted to the sprocket and the cover is in the closed position, and the cover allows the chain to be removed from or mounted to the sprocket when the cover is in the open position.
