ABSTRACT:
A chimney brush is mounted between two pulleys within the chimney for reciprocation along the length of the chimney for cleaning deposits from the chimney flue liner. A first pulley is mounted by a bracket on the chimney cap. A second pulley is mounted below the stove connection or thimbol, adjacent an access door to the second pulley. A crank arm is provided for rotation of this lower pulley so that a brush attached to a looped cable between the upper and lower pulleys may be reciprocated along the length of the chimney. A spring connection is provided between the cable and the brush to compensate for any stretching or expansion of the cable due to heating. One of the pulleys has a V groove to ensure frictional driving engagement with the cable. When not in use, the brush is disposed beneath the stove connection or thimbol of the chimney, thus only the cable remains in the chimney, minimizing interference with the smoke flow within the chimney.
