Abstract
A chimney cleaning tool for removing accumulations of foreign materials from the interior surfaces of smoke chambers and chimney flues of fireplaces and furnaces. The invention comprises a hub which is adapted to be rotated by a power driven rod, a single resilient multi-wire cable clamped to the hub and U-bolts with hex nuts for clamping the cable to the hub. The cable has loop shaped portions arranged in perpendicular relationship to the rotational axis of the hub which extend outwardly from the hub. When the tool is inserted into a chimney flue, rotated, and brought to bear against the interior surfaces of the flue, the outer portions of loops rapidly remove accumulated materials from the flue without damaging the flue. The invention can also be used for removing materials which accumulate on the walls of other conduits, such as sewers and oil well casings.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
