(12) The width of the head 26 is tapered in the plane of the tool as shown in
(13) The side surfaces (i.e. those in alignment with the plane of
(14) At an end of the breech chamber cleaning tool furthest from the head 26, i.e. adjacent region 32, there is positioned an circular section 34 having a hole 36 therethrough. The circular section 34 forms part of the region of the tool that can be used as a handle 24. As described later, the circular section 34 and the hole 36 are used to create a pivotal connection with other tool attachments.
(15) The breech chamber cleaning tool has a substantially rectangular cross section along the majority of the length thereof. In this embodiment, the width of the bar section is approximately 7 mm.
(16) Referring to
(17) Referring to
(18) The brush 69 has bristles 70 protruding at a right angle to the second region 44 of the bar section 40. In this embodiment the bristles 70 and the cap 68 are made from polyamide, for example nylon 610. However, in alternative embodiments any suitable material may be used, for example any suitable plastics, metallic or elastomeric material. In other embodiments the cap 68 may be made from a different material to the bristles 70. In further alternative embodiments, the cap may have bristles on two or more sides, for example on opposing sides of the cap portion.
(19) In the present embodiment the brush 69 is removable from the brush tool attachment 38. However, in alternative embodiments the brush may be integrally formed with the brush tool attachment. The brush may have two sets of bristles positioned on opposing sides of the brush tool arrangement.
(20) Referring back to
(21) Referring to
(22) Connected to the circular section 60 and protruding therefrom is a projection 64. It can be seen in
(23) Each of the tool attachments, including the breech chamber cleaning tool are made from mild steel. However, in alternative embodiments any suitable metals or plastics material may be used. In the present embodiment, each tool attachment is formed by stamping. Forming the tool attachments using stamping eases the manufacturing process and reduces associated costs. However, in alternative embodiments each or one or more of the tool attachments may be made from cutting the tool attachment from a plate, or by forming bar stock, or by a moulding process, or by any other suitable manufacturing method.
(24) Referring to
(25) The tool attachments are connected together via the circular sections 34, 48, 60 by a clip fitting through the holes 36, 50, 62. The clip being of a type so as to permit relative rotational motion of the tool attachments, i.e. a pivotal connection is formed.
(26) In the configuration shown in
(27) A method of cleaning a rifle with the rifle cleaning tool of
(28) At 74 in
(29) In the next step 76, the breech chamber (also known as the bolt extension or bolt extension chamber) of the rifle is scraped clean with the head 26 of the breech chamber cleaning tool 20. To do this, the rifle cleaning tool 26 is gripped in the region of the handle 24 of the breech chamber cleaning tool 20. A suitable grip is to use a thumb and two fingers. It is suitable to grip the tool in the circular region and a portion of the pointed tool attachment 52 and/or brush tool attachment 38, i.e. the other tool attachments form part of the handle.
(30) Advantageously, provision of a handle 24 of the breech chamber cleaning tool 20 so close to the head 26, when compared to the breech cleaning tool with extension rod of the prior art, allows a user to apply increased pressure and have increased feedback. Increased pressure can improve the cleaning of the rifle.
(31) The head 26 is then positioned in the breech chamber by inserting the head 26 of the breech chamber cleaning tool 20 into an inner region of the rifle from a region to one side of the rifle and the breech chamber, and then moving the breech chamber cleaning tool 20 downwards so as to insert the head into the breech chamber. The head 26 may be rotated and/or twisted so as to be in a desired orientation. Insertion of the head 26 into the chamber in this manner means that the hand is to one side of the breech chamber during cleaning of the breech chamber. It also means that the angle with which the head 26 can be positioned in the breech chamber is not restricted by a bore through which an extension rod is inserted (as with breech chamber cleaners of the prior art). The breech chamber cleaning tool 20 does not need to be inserted through a bore of the rifle which means that the head 26 can have increased dimensions compared to the breech chamber cleaning tools of the prior art.
(32) Once the head 26 is inserted in the breech chamber, a user applies a force to push the breech chamber cleaning tool 20 against the base and/or walls of the breech chamber. At the same time as applying a pushing force the head 26 is slid and/or rotated so as to scrape debris from the breech chamber. During use, the hand of the user is offset from the sides of the breech chamber.
(33) The scraping action continues for a time as desired.
(34) The head 26 is then removed from the breech chamber and cleaned if required.
(35) In the next step 78, a flannelette is positioned over the head 26. As previously described, the head 26 of the breech chamber cleaning tool 20 is then inserted in the breech chamber from one side of the breech chamber. The flannelette and head 26 are rotated and moved in the breech chamber as required to remove any debris disturbed during the scraping process.
(36) Steps 76 and 78 can be repeated as desired. For example, a white or light coloured flannelette may be used, and steps 76 and 78 may be repeated until the flannelette used to cover the head 26 is substantially unmarked when removed from the breech chamber.
(37) In alternative embodiments, a flannelette may be positioned over the head of the tool in step 76, removing the need for step 78. In such an embodiment, the breech chamber may be cleaned by scraping with the flannelette positioned over the head in a similar way as described for step 78 of the previously described method.
(38) When compared to the cleaning methods of the prior art, the present method was found to provide improved cleaning of the breech chamber.
(39) In the described embodiment, no chemical solvents were used. However, in alternative embodiments solvents may be used as required. The type of solvents suitable for such applications are well known in the art.
(40) In the next step 80 the brush tool attachment 38 is used to brush the roof and base of the breech chamber. To do this, the breech chamber cleaning tool 20 is unhooked from the projection 64 of the pointed tool attachment 52 and rotated to be aligned with the pointed tool attachment 52. The brush tool attachment 38 is then rotated away from the other tool attachments. Optionally the projection 64 of the pointed tool attachment 52 can be hooked onto the brush tool attachment 38 so as to fix its position with respect to the pointed tool attachment 52.
(41) The cap 68 of the brush 69 is then positioned on the mount 46 of the brush tool attachment 38, if it is not already in position. To clean the roof of the breech chamber the brush 69 is positioned so that the bristles 70 are in a direction towards a region formed by the angling of the brush tool attachment 38, i.e. the position shown in
(42) Once the roof of the breech chamber is sufficiently brushed, the brush 69 is removed from the region of the breech chamber. The brush 69 is then removed from the mount 46, rotated through 180 so as to be facing away from the region formed by the angling of the brush tool attachment, and positioned back on the mount 46. In a similar manner to that described for brushing the roof of the breech chamber, the base of the breech chamber is brushed.
(43) As desired, the brush may be used to clean any other regions of the rifle.
(44) In the next step 82, the pointed tool attachment 52 is used to clean intricate parts of the rifle. The intricate parts cleaned are the parts that are often undesirably cleaned using the firing pin of the rifle. To select the pointed tool attachment 52, the tool attachments are rotated in a manner similar to that described previously. The projection 64 of the pointed tool attachment 52 then hooks on to one or both of the other tool attachments.
(45) The rifle can then be reassembled in a form ready to use.
(46) Although the invention has been described above with reference to one or more preferred embodiments, it will be appreciated that various changes or modifications may be made without departing from the scope of the invention as defined in the appended claims. For example, the tool attachments may not be pivotally connected. In such embodiments, each tool attachment may be provided as a separate component. Alternatively, the breech chamber cleaning tool and/or one or more of the tool attachments may be attached to a multi-tool, or additional tool attachments may be added to the rifle cleaning tool. The multi-tool or additional tool attachments may be other rifle cleaning tools or may be other useful tool attachments such as a knife.
