DETAILED DESCRIPTION OF THE INVENTION

(7) Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, a conduit cleaning article 100 is provided in accordance with one embodiment of the present invention and includes a center structure 102 and a plurality of outer structures 104. The center structure 102 includes a center structure outer surface 106, a center structure top 108 and a center structure bottom 110 and may be cylindrical in shape. The center structure 102 defines an inner cavity 112 and a center structure opening 114 located proximate the center structure bottom 110 to be communicated with the inner cavity 112. The plurality of outer structures 104 are associated with center structure 102 to extend out of and away from the center structure outer surface 106 of the center structure 102. The plurality of outer structures 104 are arranged in an inclined fashion to form a helical shape along the center structure outer surface 106 of the center structure 102. Each of the plurality of outer structures 104 includes an outer structure width W, an outer structure front 116, an outer structure rear 118, an outer structure top surface 120, an outer structure bottom surface 122 and an interface surface 124. The interface surface 124 is located proximate the outer structure front 116 and is arranged to extend out of and away from the outer structure bottom surface 122. It is contemplated that in another embodiment, the interface surface 124 may be arranged to extend out of and away from the outer structure top surface 120.

(8) In accordance with one embodiment of the invention, the outer structure width W of the plurality of outer structures 104 located proximate the center structure bottom 110 have a width W that is larger than the width W of the plurality of outer structures 104 located proximate the center structure top 108. This allows the conduit cleaning article 100 to have a taper angle of , where is preferably about 10, but may be any taper angle between about 1 and about 30. It should be appreciate this taper allows for the conduit cleaning article 100 to be inserted, or loaded, into the conduit more easily, thereby decreasing the cleaning time and reducing the risk of breakage. Moreover, the conduit cleaning article 100 may be constructed from, or coated with, an abrasive material to help grind down and reduce the contaminants to a smaller size as it traverses the conduit. It should be appreciated that the conduit cleaning article 100 may be constructed from (partially or wholly) or coated with any abrasive material suitable to the desired end purpose, such as silicon carbide having a sufficient grit suitable to the desired end purpose. For example, depending on the application, the grit size may range from 20 grit (841 microns) to 600 grit (20 microns).

(9) It should be appreciated that a method for implementing the conduit cleaning article 100 includes inserting the conduit cleaning article 100 into a barrel, pipe, tube or other conduit such that the center structure top 108 is first into the opening of the barrel, pipe, tube or other conduit and such that the center structure bottom 110 is substantially flush with the opening to the barrel, pipe, tube or other conduit. A stream of air and/or water is forced into the opening of the barrel, pipe, tube or other conduit such that the air and/or water contacts the center structure bottom 110. As the stream of air and/or water flows contacts the conduit cleaning article 100, the stream of air and/or water flows into the inner cavity 112 and contacts the outer structure bottom surface 122 to become incident on the interface surface 124. The force of the stream of air and/or water causes the conduit cleaning article 100 to rotate and traverse the length of the barrel, pipe, tube or other conduit. For example, the vertical support causes the conduit cleaning article 100 to spin when the air and/or water hits it. Additionally, pitched blade (i.e. outer structures 104) creates spinning and cutting action on the debris on the tube wall. As the conduit cleaning article contacts the contaminants on the inner surface of the barrel, pipe, tube or other conduit, the contaminants become dislodged and flow along with the conduit cleaning article 100. Additionally, as the dislodged contaminants interact with the conduit cleaning article 100, the dislodged contaminants are reduced in size due to the abrasive material.

(10) It should be appreciated that the elements of the conduit cleaning article 100 may be constructed, wholly or partially, from any material or combination of materials suitable to the desired end purpose, such as silicon carbide, metal, plastic, rubber, composite or any combination of thereof.

(11) While the invention has been described with reference to an exemplary embodiment, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims. Moreover, unless specifically stated any use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another.
