Description

Background of the Invention

[0001] 1. Technical Field

[0002] This invention relates to a pipe cleaning kit and, more particularly, to a rotatable tool-operated pipe-cleaning kit.

[0003] 2. Prior Art

[0004] Soldering or brazing of pipe or tubing requires that the mating (or faying) surfaces of the pipe and fittings be thoroughly cleaned to present oxide-free and contaminant free surfaces which can be wetted by the molten solder or brazing alloy. This is required to form sound joints which are free of porosity and voids and which do not leak. Degreasing the joint components, if necessary, and then abrading the faying surfaces normally accomplish this.

[0005] Degreasing is accomplished by wiping with a solvent appropriate for the oily contaminant to be removed. Oxides and dry contaminants are manually removed by rubbing with dry steel wool, emery cloth, or wire brushes. They may also be removed by using motor driven brushes or emery cloth. Proper cleaning of joint members prior to soldering or brazing is essential in order to economically form sound joints. Clean joint surfaces can be rapidly soldered or brazed using a minimum of heat, flux, and filler alloy.

[0006] These economies of time, energy, and materials more than offset the cost of proper cleaning. Manual cleaning of a large number of tube/fitting joint components can become tedious and time consuming and can, thus, lead to operator inattention and error. Clearly, motor driven abrasion means can eliminate tedium and permit rapid and effective cleaning of large numbers of joint components.

[0007] Accordingly, a need remains for a pipe cleaning kit that overcomes the above-noted shortcomings.

Brief Summary of the Invention

[0008] In view of the foregoing background, it is therefore an object of the present invention to provide a device for a pipe cleaning kit. These and other objects, features, and advantages of the invention are provided by a cleaning kit operable by a power-operated tool or a manually-operated tool, for cleaning pipes and fittings to prepare same for soldering. The cleaning kit includes a plurality of sockets that preferably have substantially cylindrical bodies and a centrally disposed longitudinal axis passing therethrough. The plurality of sockets further include opposed end portions integral with the body with centrally disposed openings formed therein respectively.

[0009] The plurality of sockets further include a plurality of wire bristles attached to one of the opposed openings, preferably extending radially inwardly therefrom and towards the axis. Such bristles receive an outer surface of a pipe therealong and maintain continuous surface contact therewith for cleaning same while a tool rotatably engages the plurality of sockets about a pipe. The plurality of wire bristles are preferably formed from stainless steel, as well-known in the industry.

[0010] The present invention further includes a first shank that has a square end portion for selectively receiving the plurality of sockets therein. The first shank further has an oppositely spaced hexagonal end portion for removably connecting to a tool respectively.

[0011] The device further includes a wire brush including a lower end portion and a second shank connected thereto. The second shank advantageously has a hexagonal shape and is removably attachable to a tool so that same can be rotatably engaged with an interior of a pipe and thereby clean same. The wire brush preferably has a substantially conical shape and may further have an apex oppositely spaced from the shank. Of course, the wire brush may be formed to have alternate shapes, as well-known to a person of ordinary skill in the art.

[0012] The cleaning kit further includes a carrying case including lower and upper sections pivotally engageable with each other and for defining a cavity therebetween for storing the plurality of sockets and the shank and the wire brush therein. The carrying case may further include a handle preferably attached to the upper section and extending outwardly therefrom.

Detailed Description of the Invention

[0020] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the true scope of the invention to those skilled in the art. Like numbers refer to like elements and prime notations refer to alternate elements throughout the figures.

[0021] The assembly of this invention is referred to generally in FIGS. 1–6 by the reference numeral 10 and is intended to protect a pipe cleaning kit. It should be understood that the assembly 10 may be used to clean many different types of pipes and surfaces and therefore should not be limited to cleaning only copper pipes and associated fittings.

[0022] Referring initially to FIG. 1, the device 10 includes a cleaning kit 20 operable by a tool 30 and for cleaning pipes 40 and fittings 50 to prepare same for soldering. The cleaning kit 20 includes a plurality of sockets 21 including substantially cylindrical bodies 22 and has a centrally disposed longitudinal axis passing therethrough. The plurality of sockets 21 further include opposed end portions 23 integral with the body 22 that has centrally disposed openings 24 formed therein respectively.

[0023] The plurality of sockets 21 further include a plurality of wire bristles 25 attached to one of the opposed openings 24a, extending radially inwardly therefrom and towards the axis for receiving an outer surface of a pipe 40 therealong and maintaining continuous surface contact therewith for cleaning same while a tool 30 rotatably engages the plurality of sockets 21 about a pipe 30. The plurality of wire bristles 25 are formed from stainless steel. The device 10 can further advantageously be operated by a power-operated tool 31 or a manually-operated tool 32.

[0024] The present invention further includes a first shank 60 that has a square end portion 61 for selectively receiving the plurality of sockets 21 therein. The first shank 60 further has an oppositely spaced hexagonal end portion 62 for removably connecting to a tool 30 respectively.

[0025] The device further includes a wire brush 70 including a lower end portion 71 and a second shank 72 connected thereto. The second shank 72 advantageously has a hexagonal shape and is removably attachable to a tool 30 so that same can be rotatably engaged with the interior of a pipe 40 and thereby clean same. The wire brush 70 has a substantially conical shape and further has an apex 73 oppositely spaced from the shank 72.

[0026] The cleaning kit 20 further includes a carrying case 80 including lower 81 and upper 82 sections pivotally 83 engageable with each other, defining a cavity therebetween for storing the plurality of sockets 21 and the shank 60 and the wire brush 70 therein. The carrying case 80 further includes a handle 84 attached to the upper section 82 and extending outwardly therefrom.
