ABSTRACT:
This cleaning device utilizes two methods, simultaneously, to remove deposits from the conduction channel inside a multitude of various shaped tubes or the like, including round, square, and rectangular chimney flues. The first removes soft, brittle deposits and the second removes hard, glazed deposits through the use of chisel-like edges (35) and file-like grooved rasping surfaces (34) that are integrated in one element, the raspers (30). Raspers (30) can be replaced when dull. This device is well suited for removing creosote deposits from chimney flues; it can go past unyielding obstructions commonly found in chimney flues, and it cleans all surfaces in a section of flue simultaneously. This cleaning device consists of an elongated body (17), smaller but similar in shape to the specific shape tube or flue it is designed to clean, a plurality of semi-elliptical bowed springs (26) projecting a flexible arch outward from and normal to the body side surfaces (23) and spanning said body longitudinally, disposed in spaced-apart relation about said body to form an array with a planform shape similar to the shape of the flue to be cleaned, raspers (30) attached to and clamped around the convex surfaces (33) of the semi-elliptical bowed springs (26), and a long, thin handle (46) reversibly attached and locked onto the center of the top capped end (22) of said body (17) to provide a unitary stroking means whereby this device is reciprocated to and fro inside a flue.
