The fastest and easiest way to remove brass compression rings from copper piping. Preferably a torque handle or the like is attached to the opposite end of the spindle to the cutting part to facilitate rotation thereof.

The threaded bore may be formed in a body of the tool. Some further preferred features in accordance with embodiments of both aspects of the invention will now be described. The tool may simply be held radially outwardly of the pipe and ring and then deployed.

However it is preferred that the tool further comprises means for engaging with the pipe such that it is easier for a user to hold the tool in a fixed position relative to the pipe. The tool may be provided with means for clamping onto the pipe so that no effort is required to steady the tool or hold it in place.

As a typical water pipe made of copper tubing is relatively soft, there is a risk that the force of the part cutting through the ring and moving up against the pipe may cause the pipe to bend or otherwise deform. It is therefore preferred that there is further provided an anvil part engageable inside the pipe. The anvil part preferably contacts and supports the pipe radially inward of the cutting part on its path such that the force of the cutting part is transmitted through the pipe wall to the anvil.

The anvil part is preferably engageable against the inside of the pipe wall opposite the ring section to be severed. The anvil may be provided by a part separate from the tool, for example a handheld anvil, but in at least some preferred embodiments the anvil part is provided by the tool. In this way the anvil part can help to locate the tool relative to the pipe and ring, and help to steady the tool in use. Where the tool comprises a body, e.

In this way the number of tool parts is minimised. The tool body is advantageously a single unit which is manually engaged with the pipe and held stationary with one hand while the other hand applies the work necessary to move the cutting part relative to the body and towards the compression ring and pipe. A still further aspect of the invention provides a compression ring removal tool comprising an anvil part shaped for insertion into the end of a pipe, the anvil part connected to a tool body which also mounts a compression ring cutting part which is movable with respect to the anvil part, and a threaded or ratchet actuating means operable to forcibly engage the cutting part against a compression ring on a pipe end whilst engaged with the anvil part in use.

This aspect of the invention may include any or all of the preferred features of the other aspects described above. The invention also extends to improved methods for removing a compression ring from a pipe.

In accordance with a further aspect of the invention there is provided a method of removing a compression ring from a pipe comprising providing a cutting part and controllably moving the cutting part generally radially with respect to a pipe having a compression ring thereon, said cutting part comprising a cutter for cutting into the ring and a stop for preventing the cutter from cutting into the pipe.

In accordance with yet a further aspect of the invention there is provided a method of removing a compression ring from a pipe comprising providing a tool comprising a cutting part and applying a torque to the tool, the tool comprising means for converting the applied torque into controlled linear movement of the cutting part generally radially with respect to a pipe having a compression ring thereon. In accordance with yet a further aspect of the invention there is provided a method of removing a compression ring from a pipe comprising: providing a tool comprising a tool body, an anvil part connected to the tool body and a compression ring cutting part movably mounted to the tool body with respect to the anvil part; inserting the anvil part into the end of a pipe; and operating a threaded or ratchet actuating means to forcibly engage the cutting part against a compression ring on the pipe.

Although the tool has been described as facilitating removal of a compression ring from a pipe, it may of course find use in other situations and is not limited in its use. A preferred embodiment of the present invention will now be described, by way of example only, and with reference to the accompanying Figures, in which: Figure 1 is a perspective view of an olive removing tool in accordance with the preferred embodiment; and Figure 2 is a cross-sectional view of the tool of Figure 1 engaged into the end of a pipe in use.

There is shown in Figure 1 an olive removal tool 2 generally comprising a body part 4, an anvil part 6, and a cutting part 8. The main parts of the tool 2 are machined from a low carbon mild steel designated as BS M07 EN1A which is suitable for machining using automatic and CNC machines.

The anvil part 6 projects from the body 4 with sufficient clearance to allow it to engages inside a pipe. The anvil part 6 is solid and generally cylindrical in shape with an outer diameter of no more than 13 mm to allow it to fit inside standard size copper pipes ranging in internal diameter from 15 to 32 mm.

Although in this embodiment the anvil part 6 is fixedly connected to the body part 4, they could of course be integrally formed. The cutting part 8 is arranged opposite to the anvil part 6 with a space between them large enough to accommodate a pipe in use. As is seen more clearly from Figure 2, the cutting part 8 is slidably mounted in a cylindrical bore 10 in the tool body 4. The cutting part 8 is prevented from rotating in the bore 10 by a pin 12 extending radially between the cutting part 8 and the tool body 4.

The pin 12 is accommodated in a cavity 14 in the tool body 4 which allows for translation of the pin 12 when the cutting part 8 moves axially in the bore Abutment of the pin 12 against either end of the cavity 14 advantageously limits the movement of the cutting part 8 in and out of the bore This can be arranged to provide a final stop against movement of the cutting part 6 such that it cannot be brought into contact with the anvil part 6 and accidentally blunted.

However the pin 12 could be omitted and rotation of the cutting part 8 could instead be prevented by using a square section bore. The fore end of the cutting part 8 comprises a cutting edge 16 and a pair of stops 18 arranged either side of the cutting edge It will be seen from Figure 1 that the cutting edge 16 is formed by the apex of a wedge which extends back into the cutting part 8.

The cutting edge 16 is parallel to the axis of the opposed anvil part 6. The stops 18 are formed by squared-off blunt portions arranged above and below the cutting edge 16 in the axial direction of the anvil part 6. When the tool 2 is engaged with a pipe 30 in use, as is shown in Figure 2, the axis of the anvil part 6 is aligned with the axis of the pipe The length of the cutting edge 16 between the stops 18 is 10 mm. Of course the length of the cutting edge 16 can be adapted in a toOl for use outside the UK where standard pipe and olive diameters may be different.

The stops 18 are around mm square. The area of the stops 18 is not critical as long as it is sufficient to bring the cutting part 8 to a standstill upon contact with a pipe The aft end of the cutting part 8 is fixedly engaged with an actuating spindle The spindle 20 has an external thread and engages within an internally threaded bore 22 formed in the tool body 4.

The threaded bore 22 is an extension of the bore 10 in which the cutting part 8 moves. The distal end 24 of the spindle 20 is arranged outside of the tool body 4 and is provided with a torque handle 26, commonly referred to as a "tommy bar" in the trade, to rotate the spindle 20 and screw it in and out of the bore As the spindle 20 is wound in and out, it moves the associated cutting part 8 axially in and out of its own bore The torque handle 26 is slidably mounted in a transverse bore 28 passing through the distal end 24 of the spindle 20 so as to enable a torque to be applied from different sides.

Stop portions 29 are provided at either end of the handle 26 to prevent it from sliding out of the bore Of course a fixed handle maybe used instead but will not allow as much flexibility in operation of the tool. Operation of the tool to remove an olive 32 from a pipe 30 will now be described with reference to Figure 2. It will be seen that a compression fitting to the pipe 30 has been loosened by unscrewing the compression nut 34 and moving it down from the end of the pipe.

In hydraulic process, compression fittings basically assure some secure fit in pipe connections. RTJ rings can be reused in a tight fit joint. Place the lower end of the open jaws into the PEX compression fitting , and then close it tightly over the top. This is done by pushing the two handles together. Once you have done this, push the handles of the tool until the ring splits open.

Also fit a new insert on every joint. As to cutting the pipe, the real cutters are basically a stanley knife blade in a shaped holder, use a very sharp blade to cut the speedfit pipe, ensuring a square cut.

Shut off the water to the pipe from which you are going to remove the compression fitting.
