Chimney cleaning tool |
摘要 |
A chimney cleaning tool which is adapted to be inserted on the end of a power driven motor such as an electric drill. The tool has an attachment device carried on a remote end of an elongated shaft. Elongated multistrand steel twisted cables extend outwardly from the attachment device. The outer ends of the twisted cables are circumferentially spaced from each other and are free to untwist to form a plurality of brush-like heads for cleaning chimneys and the like. A restricting member is carried on each of the multistrand twisted cables intermediate the outer and inner ends, limiting the extent that the cables can untwist from the outer ends inwardly towards the inner ends.
