CHIMNEY CLEANING APPARATUS Abstract A chimney cleaning system is permanently installed on a chimney for cleaning a flue of the chimney by either manual or automatic operation. The flue brush is seated in the chimney flue with cables also inside the flue secured to both ends of the brush for pulling the brush either upward or downward. A control box with a clutch mechanism for actuating or driving the cables in either direction by manual or automatic operation is installed outside the chimney at a convenient selected location on the side of the chimney. First and second lengths of cable secured to the top and bottom of the flue brush pass around pulleys mounted or anchored at the top and bottom of the chimney, then pass through guide sleeves and holes drilled in the side of the chimney to the control box. The control box is provided with a crank shaft and first and second reels mounted on the crank shaft for free wheeling on the shaft. A clutch mechanism upon actuation engages the shaft with either the first or second reel for rotation of either the first or second reel with the shaft while the other reel remains free wheeling. Thus, the reels can rotate in opposite directions on the same shaft reeling in one length of cable for pulling the brush in a desired direction while paying out the other length of cable on the slack side of the brush. The crank shaft can be rotated by either a manual crank or a motor such as an electric hand drill.
