Abstract
Discloses a portable chimney device for removing creosote deposits and soot from a chimney flue while the chimney is in operation, or during a chimney fire, and without said device causing damage to the chimney flue, its liner, or chimney bottom. The device has a frame mounting a drum reel whose cable is operatively connected to an impacting weight freely carrying upper and lower cutters with a spacer ring therebetween, with such cutters disposed between upper and bottom rings fixed to the impacting weight. Upward and downward movements of the frame transmit ramming impact by means of the fixed rings to the cutters to effect removal of the creosote deposits and soot. Also discloses a portable chimney device to clean the chimney flue of creosote deposits and soot as a matter of periodic maintenance. The device has a frame mounting a drum reel whose cable is operatively connected to an impacting weight freely mounting spacer washers and a sub-assembly of upper and lower washers sandwiching articulated, spring-steel picks. Such sub-assembly is freely carried on the impacting weight between the spacer washers. Upward and downward movements of the frame transmit ramming impact to the sub-assembly of picks through the spacer washers with removal of the creosote deposits and soot effected by engagement of the picks therewith, and with such articulation of the picks causing unidirectional rotation of the picks.
