Abstract
Flue cleaning apparatus comprises a bladed scraper head suspended by cable in a flue from pulleys on a mounting attachment secured at the top of the flue so that the cable can be operated from outside of a building of which the flue forms a part, to move the scraper head up and down in the flue for cleaning creosote and like deposits from the surfaces thereof. The scraper head incorporates alignment blades for guiding the scraper head off of irregularities which might be present in a flue, and a movable weight which can be used to hammer against the scraper head should it become lodged in a flue thereby assisting in dislodging same.
