Abstract

Disclosed is a pipe cleaner apparatus that is attached to a pipe fusion machine. The pipe cleaner removes dirt, snow, mud, and other debris from the outer surface of pipe sections prior to the butt fusion process. The pipe cleaner may be a wiper through which the pipe slides, or may be a multi-piece scraper with spring loaded flaps that clean the outside surface of the pipe.

Claims (26)

1. A pipe fusion machine for fusing sections of pipe to form a pipeline, comprising:

(a) a fusing mechanism; and

(b) a cleaning mechanism for cleaning debris from the external surface of the sections of pipe prior to fusion of the same, said cleaning mechanism comprising:

a first discus plate having, with respect to said cleaning mechanism, an interior surface,

a second discus plate having, with respect to said cleaning mechanism, an interior surface,

a flexible discus wiper having planar surfaces, wherein the interior surfaces of said first and second discus plates and the planar surfaces of said flexible discus wiper are in a parallel configuration, and

a plurality of independent spacers removably affixed to the interior surface of said first discus plate and the interior surface of said second discus plate, said spacers connecting and separating said discus plates, and being sized and positioned to allow said flexible discus wiper to be held between said interior surfaces of said discus plates.

2. The pipe fusion machine of claim 1 , wherein at least one of said spacers is removably affixed to said discus plates so that, when removed from said discus plates, said flexible discus wiper may be removed from between said discus plates.

3. The pipe fusion machine of claim 1 , wherein said flexible discus wiper comprises a disk having an aperture therethrough, the circumference of said aperture being defined by the inside edge of said disk.

4. The pipe fusion machine of claim 3 , wherein the pipe sections being fused by the pipe fusion machine have corresponding diameters, and wherein the diameter of the aperture of said flexible discus wiper is slightly less than the corresponding diameters of said pipe sections.

5. A pipe cleaner for use with a pipe fusion machine, comprising:

(a) a first discus plate having, with respect to said pipe cleaner, an interior surface,

(b) a second discus plate having, with respect to said pipe cleaner, an interior surface,

(c) a flexible discus wiper, wherein the interior surface of said first and second discus plates and the planar surfaces of said flexible discus wiper are in a parallel configuration, and

(d) a plurality of independent spacers removably affixed to the interior surface of said first discus plate and the interior surface of said second discus plate, said spacers connecting and separating said discus plates, and being sized and positioned to allow said flexible discus wiper to be held between said interior surfaces of said discus plates.

6. The pipe cleaner of claim 5 , wherein at least one of said spacers is removably affixed to said discus plates so that, when removed from said discus plates, said flexible discus wiper may be removed from between said discus plates.

7. The pipe cleaner of claim 5 , wherein said flexible discus wiper comprises a disk having an aperture therethrough, the circumference of said aperture being defined by the inside edge of said disk.

8. The pipe cleaner of claim 7 , wherein the pipe sections being fused by the pipe fusion machine have corresponding diameters, and wherein the diameter of the aperture of said flexible discus wiper is slightly less than the corresponding diameters of said pipe sections.

9. An improved method for fusing sections of pipe, whereby the improvement comprises cleaning the sections of pipe prior to the fusion of the same by means of a cleaning mechanism comprising:

(a) a first discus plate having, with respect to said pipe cleaner, an interior surface,

(b) a second discus plate having, with respect to said pipe cleaner, an interior surface,

(c) a flexible discus wiper having planar surfaces, wherein the interior surfaces of said first and second discus plates and the planar surfaces of said flexible discus wiper are in a parallel configuration, and

(d) a plurality of independent spacers removably affixed to the interior surface of said first discus plate and the interior surface of said second discus plate, said spacers connecting and separating said discus plates, and being sized and positioned to allow said flexible discus wiper to be held between said interior surfaces of said discus plates.

10. The method of claim 9 , wherein at least one of said spacers is removably affixed to said discus plates so that, when removed from said discus plates, said flexible discus wiper may be removed from between said discus plates.

11. The method of claim 9 , wherein said flexible discus wiper comprises a disk having an aperture therethrough, the circumference of said aperture being defined by the inside edge of said disk.

12. The method of claim 11 , wherein the pipe sections being fused by the pipe fusion machine have corresponding diameters, and wherein the diameter of the aperture of said flexible discus wiper is slightly less than the corresponding diameters of said pipe sections.
