ABSTRACT:
A chimney cleaner of universal application and especially suitable for cleaning heavy wood resin residue is disclosed. An A-frame assembly capable of expansion and contraction to accommodate various chimney sizes is held together by pivot connections. The manual reciprocation of the cleaner by a user through a rod which forms the cross bar of the A-frame produces a longitudinal reciprocation of the A-frame. A right angled brush may be removably mounted on the A-frame along its top and fits into a chimney outwardly from a corner. The legs of the A-frame end in wheels which ride up and down the chimney corner opposite the brush. The chimney cleaner's overall dimensions may be increased or decreased by applying a torque to the rod which, through a threaded connection with a leg, will cause the legs to spread or contract.
