  • Patent number: 4333200
    Abstract: A chimney cleaner device cleans the inside surfaces of a chimney in both an upward and downward direction. The device includes a pair of diverging cleaning arms made of heavy metal, each arm having an integral shank portion and blade portion. The blade portion has an outermost scraping edge and a beveled surface slanting inwardly from the cleaning edge to an end of the blade portion opposite the shank portion. The cleaning arms are pivotally connected at an end of the shank portion opposite the blade portion, and are biased outwardly about the pivotal connection in a diverging manner by a lateral force such that the scraping edges engage the inside surfaces of the chimney. The combination of the weight of the cleaning arms and the beveled surface are sufficient to overcome the lateral force allowing downward scraping of the chimney. Upward cleaning of the chimney is accomplished by simply pulling the device up the chimney.
