ABSTRACT:
BACKGROUND OF INVENTION
The present invention relates to a cleaning tool which can be used to simultaneously clean the outside surface and the inside surface of an end of a copper pipe in preparation for soldering.
Pipe cleaning tools are known for cleaning the inside and outside surfaces of a pipe to be joined prior to soldering. See, for example, U.S. Pat. No. 4,862,549 to Criswell, et al., and U.S. Pat. No. 5,493,748 to Santo.
The present invention provides a tool for cleaning the outside and inside surfaces of a pipe of various diameters merely by reversing the tool ends. With the present invention, the tool is inserted in a chuck of a power drill and can be used easily to clean the exterior and interior surfaces of ½″ pipes or ¾″ pipes easily, simply by reversing the body of the tool.
SUMMERY OF INVENTION
The present invention relates to a two-ended copper pipe cleaning tool which can be used to simultaneously clean the outside surface and the inside surface of an end of a copper pipe in preparation for soldering. One end of the tool is used for cleaning a pipe having a first diameter, and the second end of the tool is used for cleaning a pipe having a larger size diameter. The invention includes a holder body having a first tubular portion flaring into a second tubular portion. A wall separates the first tubular portion from the second tubular portion. A hard wire brush is affixed to the inner surface of the first tubular portion, and a hard wire brush is affixed to the inner surface of the second tubular portion. A drive shank is provided having an end for use in a chuck or collet of a drill, and a free end sized to be received either by a socket located in the first tubular bore or a socket provided in the second tubular bore. Further, a brush shank is provided having a hard wire brush attached at one end. The free end of the brush shank sized to be removably received by either the first or second tubular sockets.
