ABSTRACT:
A pipe joint cleaner device primarily for plastic pipes which after being cut are to be joined together comprising an open tapered cone member having a plurality of sharp raised projections on both the exterior face of such cone and on the interior face thereof whereby when a cut piece of pipe is inserted into the interior of the cone, in contact therewith, and relative rotation is induced between the pipe and the cone, any burrs or slivers on the exterior end and surface of such pipe are removed by contact with the projections on the interior face of such cone and, conversely, when the tip of the cone is inserted into a cut piece of pipe until firm contact with the exterior of the cone results and again relative rotation takes place, any burrs or slivers on the inside of such pipe end will be removed by the projections on the exterior face of such cone. Due to the cone shape, the device is substantially self-centering, eliminating the need for complicated jigs or the like.
