ABSTRACT:
A brush for cleaning a chimney flue is formed from a central hub outwardly from which extends a plurality of plastics strips manufactured from strapping tape having a width of the order of 1/2 inch and a thickness of the order of 0.030 inch. The device is manufactured from a plurality of separate units each formed with six outwardly extending strips or blades and a central hub with all of the units stacked on a bolt and prevented from rotation each relative to the next. A natural curvature of the strips tends to form a device into a cone shape so they can be readily pressed into a chimney flue from the lower end with the flexibility of the strapping tape enabling the unit to be compressed and passed around obstructions such as the flue damper.
