ABSTRACT:
A chimney cleaning apparatus (10) is suspended from a chain (34) for movement through a chimney flue (16) and includes a scraping plate (12). The outer periphery of the scraping plate (12) conforms to the cross-sectional shape of the chimney flue (16) and is rigid for unyielding by moving through the flue (16) in a perfectly transverse orientation to clean all debris therefrom. The scraping plate (12) is slidable along a weighted shaft (22) for enabling the apparatus (10) to be hammered through the chimney flue (16).
