Patent ID: 8347446

Claim:
A tool for cleaning a drainage structure, comprising: a rod having a center longitudinal axis and a fluid-conducting channel in fluid-communication with at least one nozzle opening disposed about the rod; a barrel housing having a cylindrical inside and outside profile compatible with a cross-sectional shape of a drainage structure and having a proximal opening and a distal opening, the barrel housing having a center longitudinal axis and coupled coaxially to the rod, the barrel housing having an outside dimension that can be accommodated within a drainage structure; a plurality of cutting implements disposed inside the barrel housing radially coupled to and spanning the rod and a cylindrical internal surface of the barrel housing so that the rod is secured to the inside profile of the barrel housing by the cutting implements, each of the cutting implements having a distal cutting edge which extends in a lengthwise direction of the cutting implement and a forwardly facing sweeping face that is angularly oriented to facilitate sweeping debris in a selected direction, each of the cutting edges has opposite ends thereof that are spaced from one another in a direction along the center longitudinal axis; and the barrel housing and cutting implements are operable to rotate about the center longitudinal axis of the rod to dislodge and loosen debris inside the drainage structure.
