Description
Background of the Invention
The present invention relates generally to gun barrel cleaning devices, and more particularly, to a gun barrel cleaner having a flexible shaft and a compact container for storing and transporting such a gun barrel cleaner.
Although a sportsman's firearm is typically cleaned at home, it sometimes is desirable or absolutely necessary to clean a gun barrel in a field or camp. For example, if a gun barrel bore becomes clogged with mud or snow while a sportsman is hunting, the hunter must for his own safety remove the obstruction from the barrel bore. Often, when a hunter has such a bore obstruction in his gun it is not convenient or expeditious for him to return home for the sole purpose of cleaning the gun barrel.
In the past, most gun barrel cleaning devices comprised an elongated rigid rod having a cleaning brush secured to one end. Such cleaning devices were obviously cumbersome to transport and difficult to store because of their length and rigidity. Many attempts have been made to produce a less cumbersome gun barrel cleaning device. For example, Lewis et al., in U.S. Pat. No. 3,208,302, and Schnitger, in U.S. Pat. No. 2,559,376, each disclose an elongated gun cleaning device constructed of a plurality of axially aligned pieces which can be partially disassembled. Even so, in both devices a relatively long length of rigid rod remains, to which pieces can be added. Thus, these devices are still quite cumbersome to store and transport.
Another, more effective, approach to producing a less cumbersome product has been to incorporate a flexible cleaning shaft as part of the gun barrel cleaning/device. For example, Malesky, in U.S. Pat. No. 4,399,627, discloses a gun cleaning device having an elongated flexible shaft with a slotted link swivelly secured to one end of the flexible shaft and a tubular coupling member swivelly secured to the other end of the flexible shaft. The shaft essentially consists of several layers of tightly wound metal coil and is sufficiently flexible to be wound yet is resistant to torque. There are several drawbacks, however, to such known gun barrel cleaning devices having flexible cleaning shafts.
First and most importantly, such gun cleaning devices can only endure the application of fairly low pressures before breaking. It may be desirous in the course of cleaning a gun barrel to pull a relatively large cleaning patch through a gun barrel bore to effect a more efficient cleaning of the barrel. If a slightly oversized cleaning patch is to be pulled through a barrel bore, the application of significant pulling force or pressure may be necessary, the magnitude of which most cleaning devices having flexible shafts are unable to withstand. Obviously, should a portion of a gun barrel cleaning device break within a barrel bore, a bore obstruction is created which will be difficult and time consuming to remove.
Secondly, such gun barrel cleaning devices are normally restricted either in terms of the range of gun barrel bore diameters which may be properly cleaned thereby or in terms of the number and type of cleaning tip combinations which may be attached to the flexible shaft to facilitate gun barrel cleaning. For example, in the noted Malesky patent since the flexible shaft has a slotted link permanently swivelly secured at one end, a limited number of cleaning tip combinations are possible, which necessarily restricts the versatility and usefulness of the cleaning device.
Lastly, such gun barrel cleaning devices generally have inadequate, inconvenient or unnecessarily limiting storage and transportation containers or structures. For example, Goodwin et al., in U.S. Pat. No. 2,897,525, describes a cleaning device having two different cleaning tips secured to opposite ends of a flexible cleaning shaft. One cleaning tip has a slot or eye therein and the other tip consists of a brush with an elongated portion at its free end such that when the flexible shaft is coiled the elongated portion is capable of being engageably retained within the eye, thereby ensuring the cleaning shaft remains in a coiled position. There are several drawbacks, however, to such a storage approach, primarily resulting from permanent attachment of the cleaning tips to the flexible shaft. Since the cleaning tips are affixed to the flexible shaft a somewhat larger coiled form than could otherwise be obtained necessarily exists and the versatility and usefulness of the cleaning device is necessarily limited.
Therefore, there presently exists a genuine need for a gun barrel cleaning device having a flexible shaft which is capable of withstanding moderate and high pulling stresses, and which is capable of cleaning a wide range of gun barrels quickly and efficiently. Further, there is a need for a compact container for storing and transporting such a gun barrel cleaner.
Summary of the Invention
Accordingly, it is a primary object of the present invention to provide an improved gun barrel cleaner having a flexible shaft capable of withstanding moderate to high pulling stresses.
Another object of the present invention is to provide a gun barrel cleaner which can clean a wide range of gun barrels quickly and efficiently.
Still another object of the present invention is to provide a gun barrel cleaner container which is compact and can fit within a sportsman's clothing pocket for easy storing and transporting of the gun barrel cleaner.
A further object of the present invention is to provide a gun barrel cleaner which does not scratch or otherwise damage a gun barrel.
A still further object of the present invention is to provide a gun barrel bore obstruction remover which can dislodge a bore obstruction, and particularly a bullet obstruction, safely and efficiently.
It is yet another object of the present invention to provide an improved method of attaching a cleaning patch to a gun barrel cleaning tip having a patch receiving slot therein, to effect a more efficient cleaning of a gun barrel.
The present invention accomplishes these objects in one aspect by providing a gun barrel cleaner having a flexible shaft substantially unyielding in an axial direction for barrel cleaning and laterally bendable for compact coiling. Secured to each opposite end of the flexible shaft is a universal coupling; each coupling having a substantially identical threaded internal bore. In addition, at least two different cleaning tips are provided which have threaded stems capable of selective threadable and detachable engagment with the threaded internal bore within either of the universal couplings, thereby facilitating cleaning of a gun barrel and storage of the gun barrel cleaner. A compact container for storing and transporting such a gun barrel cleaner is also provided.
In another aspect of the present invention, a gun barrel bore obstruction remover cleaning tip having a cylindrical body portion, a concave face at one end and means for securing the cleaning tip to a gun barrel cleaning shaft at the other end, is provided. The obstruction remover cleaning tip operates to dislodge barrel bore obstructions by impacting such obstructions. When a bullet is lodged within a barrel bore, the obstruction remover cleaning tip is maintained in a centered position about the bullet by the concave end face, thereby facilitating safe removal of the obstruction.
In yet another aspect of the present invention, a method of affixing a cleaning patch having at least one hole or slot therein to a gun barrel cleaning tip having a patch receiving slot is provided. The method includes the steps of placing one end of the cleaning tip through a hole in the cleaning patch, holding the patch near the cleaning tip's patch receiving slot, folding an edge portion of the patch together on either side of the cleaning tip, feeding the folded edge portion back through the patch receiving slot and pulling the folded edge taut so that when the combination is pulled through a gun barrel bore the cleaning patch will surround the cleaning tip in a substantially uniform manner, thus ensuring a more efficient cleaning of the gun barrel.

Detailed Description of the Invention
One embodiment of a gun barrel cleaner, generally denoted as 10, is shown perspectively in FIG. 1. Gun barrel cleaner 10 has a flexible shaft 12 which is substantially unyielding in an axial direction for gun barrel cleaning and laterally coilable for compact storing. Attached to opposite ends of shaft 12 are universal couplings 14a and 14b. Each coupling 14a and 14b has a substantially identical threaded internal bore 16a and 16b, respectively, at its free end 18a and 18b. Selectively threadably attachable to couplings 14a and 14b are gun barrel cleaning tips 20, 22 (via adaptor coupling 24), 26, 28 and 30.
Cleaning tips 20 and 22 each have a cleaning patch receiving slot 32 and 34 therein, respectively. Cleaning tip 20 is dimensioned to pass through and effectively clean (when combined with a cleaning patch) a rifle barrel and cleaning tip 22 is dimensioned to pass through and effectively clean a shotgun barrel. A threaded stem 36 capable of threadably and detachably engaging either coupling 14a or 14b is provided at one end of cleaning tip 20. Because it is dimensioned for cleaning a shotgun barrel, cleaning tip 22 has a larger threaded stem 38 at one end. An adaptor coupling 24 having a threaded stem 40 at one end capable of threadably and detachably engaging either universal coupling 14a or 14b, and a threaded internal bore 42 at the other end, is provided. Stem 38 is dimensioned to threadably engage internal bore 42 in adaptor coupling 24, the combination of cleaning tip 22 and coupling 24 being securable to either universal coupling 14a or 14b by stem 40.
Cleaning tip 26 comprises a T-shaped handle including an elongated portion 44 having a smooth transverse bore 46 therethrough. Located within bore 46 is a cylindrical bar 48. One end of cleaning tip 26 has a threaded stem 50 for threadable and detachable engagement with either universal coupling 14a or 14b. As discussed below, gun barrel cleaner 10 is capable of withstanding significant pulling force or pressure without breaking. Cleaning tip 26 facilitates the application during gun barrel cleaning of moderate to high pulling pressure by providing structure by which an individual can securely grip the gun barrel cleaner.
Cleaning tips 28 and 30 comprise gun barrel bore obstruction removers. Cleaning tip 28 has a cylindrical body portion 52 dimensioned for cleaning a rifle barrel and cleaning tip 30 has a cylindrical body portion 54 dimensioned for cleaning a shotgun barrel. Cleaning tips 28 and 30 each have a concave face 56 and 58, respectively, at one end and a threaded stem 60 and 62 (see FIG. 4), respectively, at the other end. As discussed below, concave end faces 56 and 58 are particularly designed to assist in the safe removal of bullet obstructions. Threaded stems 60 and 62 are dimensioned to threadably and detachably engage either universal coupling 14a or 14b. When attached to shaft 12, either cleaning tip 28 or 30 operates to dislodge a gun barrel bore obstruction by impacting the obstruction. Because of this, they are preferably solid and manufactured from a fairly heavy material so as to provide sufficient impacting weight. As hereinafter discussed in connection with FIG. 4, a unique means of attaching cleaning tip 30 to couplings 14a is provided due to the weight of shotgun cleaning tip 30.
A cross-section of flexible shaft 12 is shown in FIG. 2. Shaft 12 comprises galvanized steel wire bundles 66, 68, 70, 72, 74 and 76 spirally wound about a core, galvanized steel wire bundle 78. Each wire bundle consists of a plurality of wires, seven wires having been found to work particularly well. Although this 49-wire arrangement is preferred, it should be understood that the present invention is not limited to just such an arrangement. For example, the number of wires in the bundles, the number of wire bundles or both may vary. Surrounding wire bundles 66, 68, 70, 72, 74, 76 and 78 is a protective nylon coating 80 capable of shedding solvents, dirt and other abrasive materials which could scratch or otherwise damage a gun barrel. Coating 80 is applied to the wrapped wire bundles by drawing the bundles through a bath of extrudable nylon and then a forming die. Other materials could be used for coating 80, e.g. vinyl, polyethylene or polypropylene. The 49-wire arrangement coated with nylon however, is preferred since such a construction results in a very flexible shaft which can be easily stored in a very compact container. Lastly with respect to shaft 12, it is desirable to minimize for compact storage the length of shaft 12 to the extent possible without sacrificing function. Thirty inches is believed the minimum length needed to clean any rifle or shotgun barrel after cleaning tips have been attached to couplings 14a and 14b.
As already noted, attached to opposite ends of shaft 12 are couplings 14a and 14b. Preferably, couplings 14a and 14b are manufactured of brass and crimped or cold welded onto the ends of shaft 12. Referring to FIG. 3, coupling 14a is cold welded onto the end of shaft 12 (as is coupling 14b) primarily over a bare wire interior section 82, comprising the combination of wire bundles 66, 68, 70, 72, 74, 76 and 78, and partially over a wire interior coated with nylon section 84. The end of coupling 14a to be cold welded onto shaft 12 is preferably closely toleranced to sections 82 and 84.
Cold welding of couplings 14a and 14b to shaft 12 is accomplished in a standard manner, for example a hydraulic or mechanical press and a hexagonal shaped die may be used. Cold welding each coupling 14a and 14b three times on different sides using a 15-ton hydraulic press is believed preferable to accomplish the objectives of the present invention. When cold welded, brass from couplings 14a and 14b flows within and meshes with the numerous surfaces formed by the combination of wire bundles 66, 68, 70, 72, 74, 76 and 78. This action produces the unexpectedly strong securement of couplings 14a and 14b to shaft 12. Most, if not all, previous gun barrel devices having flexible shafts can only withstand pulling pressures in the 50-150 pound range (150 pounds being the minimum acceptable breaking point dictated by military specifications). Gun barrel cleaner 10 however, can consistently withstand pulling pressures in the 150-400 pound range without breaking, which provides a significant advantage over prior compactable cleaning devices having flexible shafts.
As noted, couplings 14a and 14b are preferably cold welded partially over a wire interior coated with nylon section 84. This ensures wire interior 82 will not be exposed should coupling 14a or 14b become bent, thus preventing either the possibility of corrosive materials reaching wire interior 82 where they could be retained or the possibility of having an exposed end of nylon coating 80 which could be damaged, or both. Lastly with respect to FIG. 3, threaded bore 16a is preferably undercut at free end 18a to provide a relief area 17a. This ensures that cleaning tips 20, 26, 28 and 30 and adaptor 24 will be fully threadably securable therein. Universal coupling 14b and adaptor coupling 24 are also provided with similar areas of relief. An important benefit of providing relief areas within the couplings' threaded bores instead of on the cleaning tips' threaded stems is the increased force needed to break a cleaning tip from a coupling, thus providing a more durable gun cleaning device.
Cleaning tip 30, designed to remove bore obstructions from shotgun barrels, will now be described in greater detail with reference to FIG. 4 where cleaning tip 30, universal coupling 14a and a bullet obstruction 86 are shown in cross-sectional view within a shotgun barrel 88. As described briefly above, cleaning tip 30 has a cylindrical body portion 54, a concave face 58 at one end and a threaded stem 62 at the other. Threaded stem 62 is located within a smooth internal bore 90 in the end of body portion 54 opposite that end having concave face 58. Threaded stem 62 is threadably secured at one end 92 within a threaded bore 94 in cylindrical body portion 54. An allen head 96, adapted to receive an appropriate hexagonal wrench tool, is provided in the free end 98 of threaded stem 62 to facilitate securement of stem 62 within bore 94. Internal bore 90 is dimensioned such that couplings 14a and 14b may be selectively positioned therein to threadably and detachably engage threaded stem 62. By recessing threaded stem 62 within smooth internal bore 90, strong securement of coupling 14a against lateral side pressure P.sub.s is obtained. This is because coupling 14a partially resides within internal bore 90, thus side pressures P.sub.s are partially absorbed by the external surface of coupling 14a contacting the internal surface of bore 90. Obviously, for the contacting of these surfaces to absorb significant side pressure they must be fairly closely toleranced when constructed.
As shown in FIG. 4, concave end face 58 assists in centering cleaning tip 30 about bullet obstruction 86. This reduces the chance of lodged bullet 86 accidentally exploding within gun barrel 88 when being removed since there is less chance of cleaning tip 30 being trapped between the inner surface of gun barrel 88 and bullet 86. The particular dimensions of concave end face 58 can vary, but should be sufficient to accomplish the objective of centering cleaning tip 30 about bullet 86.
In addition to couplings 14a and 14b, cleaning tips 20, 22, 26, 28 and 30 along with adaptor coupling 24, are preferably manufactured of brass. Brass is preferable since it is a "soft" metal which is less likely to scratch or otherwise damage a gun barrel. Further, each brass coupling and cleaning tip is chromic bright dipped to remove hardened surface impurities, and then lightly sealed to prevent surface corrosion, which makes these components even less likely to damage a gun barrel. Adaptor coupling 24 and cleaning tips 28 and 30 each have knurled sections 104, 106 and 108 respectively, which facilitate an individual's ability to attach and detach these components to and from couplings 14a and 14b.
An alternate embodiment 10' of the gun barrel cleaner invention is shown perspectively in FIG. 5. Gun barrel cleaner 10' includes a flexible shaft 12' substantially identical to shaft 12 of gun barrel cleaner 10, and a universal coupling 14', substantially identical to universal couplings 14a and 14b, secured to one of shaft 12'. Coupling 14' includes a threaded internal bore 16' to which different cleaning tips may be threadably attached. Secured to the other end of shaft 12' is a combination cleaning tip 112. Cleaning tip 112 and coupling 14' are preferably manufactured of brass and similarly secured to shaft 12' as explained above in connection with securement of couplings 14a and 14b to shaft 12.
Cleaning tip 112 comprises in part an obstruction remover similar in operation to cleaning tips 28 and 30. Cleaning tip 112 has a cylindrical body portion 114 and a concave face 116 at its free end 118. Additionally, cleaning tip 112 has a smooth bore 120 transverse through cylindrical body portion 114. A smooth cylindrical bar 122 is also provided and dimensioned for insertion into bore 120. When cylindrical bar 122 is located within bore 120 a T-shaped handle is formed by cleaning tip 112. This T-shaped handle may be used to facilitate the application during gun barrel cleaning of increased pulling pressure to gun barrel cleaner 10'.
Another embodiment 124, specifically designed for cleaning pistols, of the gun barrel cleaner of the present invention is illustrated in FIG. 6. Gun barrel cleaner 124 comprises several cleaning tips and cylindrical cleaning tubes which can be selectively attached to and detached from each other. A first cylindrical cleaning tube or rod 126 has substantially identical threaded internal bores 128a and 128b at opposite ends. A plurality of second cylindrical cleaning tubes or rods 130, 132 and 134, have threaded internal bores 136a, 136b and 136c, respectively, at one end and threaded stems 138a, 138b and 138c, respectively, at their other ends. Threaded internal bores 136a, 136b and 138c are substantially identical to bores 128a, and 128b in a rod 126. Threaded stems 138a, 138b and 138c are capable of selective threadable and detachable engagement with either threaded bores 128a, 128b, 136a, 136b or 136c.
Cleaning tips included within gun barrel cleaner 124 comprise: an obstruction remover cleaning tip 140, a T-shaped handle cleaning tip 142 and a slotted, patch receiving cleaning tip 144. Each cleaning tip 140, 142 and 144 has a threaded stem 146, 148 and 150, respectively, at one end capable of selective threadable and detachable engagement with threaded bores 128a, 128b, 136a, 136b and 136c. Cleaning tips 140 and 144 are dimensioned to pass through and clean pistol barrels and chambers, but otherwise are identical to cleaning tips 28 and 20, respectively, of gun barrel cleaner 10 discussed above. Obstruction remover tip 140 has a cylindrical body portion 152 and a concave face 154 at one end 156, and cleaning tip 144 has a patch receiving slot 166 therein. Cleaning tip 142 has an elongated body 158 with a smooth transverse bore 160 therethrough. Slidably entrained, by partially flattened or staked ends 164a and 164b, within transverse bore 160 is a cylindrical bar 162.
As described in connection with gun barrel cleaner 10, first cylindrical rod 126, second cylindrical rods 130, 132 and 134, and cleaning tips 140, 142 and 144 are preferably manufactured of brass, and chemically treated in a chromic acid bath to remove surface impurities and then sealed to prevent corrosion. Individual lengths of three inches for first cylindrical rod 126 and second cylindrical rods 130, 132 and 134 are preferable for storage, and cleaning of most pistol barrels and chambers.
In operation, gun barrel cleaner 124 only requires assemblage of those components necessary to accomplish the particular cleaning task desired. For example, if a short barrel, chamber, or revolver cylinder is to be cleaned, first cylindrical rod 126 and the appropriate cleaning tips may be sufficient. By being able to appropriately size the gun barrel cleaner needed, increased leverage is available for cleaning as compared with typically oversized gun barrel cleaners. Flexibility is an important feature of gun barrel cleaner 124. Cleaning tip 142 further enhances the versatility of gun barrel cleaner 124. Since cylindrical bar 162 is slidable relative to elongated portion 158, cleaning tip 142 can be used in close proximity to a pistol being cleaned without hampering the cleaning operation.
A gun barrel cleaning kit 170 of the present invention is shown perspectively in FIG. 7. Cleaning kit 170 comprises gun barrel cleaner 10, a compact container 172, a refillable vial 178 of barrel cleaning solution and several gun barrel cleaning patches 180. Alternatively, gun barrel cleaner 10' or gun barrel cleaner 124 could be included individually or in combination within gun barrel cleaning kit 170.
When closed, compact container 172 has a short cylindrical shape with preferable dimensions of approximately 3 and 178 inches in diameter and 1 inch in height. Such dimensions are important in that they allow container 172 to be conveniently inserted within a typical shirt, pants or coat pocket for carrying. Container 172 includes a bottom portion 174 and a removable top portion 176. Bottom portion 174 has a substantially flat bottom surface 182 and a continuous cylindrical side wall 184 extending therefrom. Integrally formed with cylindrical side wall 184 is an outwardly protruding ledge 186 and an internally protruding lip 188. Internally protruding lip 188, preferably located near the top edge 187 of cylindrical side wall 184, operates to retain shaft 12 with couplings 14a and 14b secured thereto in a coiled position within bottom portion 184. This lip therefore enhances safety by requiring an individual to manually remove shaft 12 rather than allowing shaft 12 to "spring out" from container 172 whenever top portion 176 is removed from bottom portion 174.
Top portion 176 includes a substantially flat top surface 190 with a continuous cylindrical side wall 192 projecting therefrom. The diameter of cylindrical side wall 192 of top portion 176 is slightly greater than that of cylindrical side wall 184 of bottom portion 174 so that top portion 176 will fit over bottom portion 174. When closed, free edge 194 of cylindrical side wall 192 engages protruding ledge 186 in bottom portion 174 to form a watertight seal. Valleys 196 and 198 in free edge 194 of top portion 176 provide a convenient method to open container 172 in a well known manner (i.e., by the application of downward pressure to top surface 190 near either valley 196 or 198). Container 172 may have camouflage coloring on its exterior surfaces if desired. Gun cleaner 10, vial 178 and cleaning patches 180 are all designed to fit within container 172.
Lastly, an improved method of attaching a gun barrel cleaning patch 200 to a cleaning tip 206 having a patch receiving slot 208 therein will be described with reference to the illustrations of FIGS. 8a-e. Cleaning patch 200 comprises a circular body member having a first hole 202 near its center and a second hole 204 close to an edge. The improved patch attachment method includes the steps of placing cleaning patch 200 over an end 210 of cleaning tip 206 (see FIG. 8a), folding an edge portion 212 of cleaning patch 200 together on either side of cleaning tip 206 (see FIG. 8b), feeding folded portion 212 of cleaning patch 200 through patch receiving slot 205 (see FIG. 8c) and pulling taut folded portion 212 through patch receiving slot 208 (see FIG. 8d). When cleaning tip 206 having cleaning patch 200 secured thereto in such a manner is pulled through a gun barrel bore, cleaning patch 200 surrounds cleaning tip 206 in a substantially uniform manner and thus provides enhanced gun barrel cleaning (see FIG. 8e). For large diameter gun barrels, end 210 of cleaning tip 206 is placed through first hole 202 and for small diameter gun barrels, it is placed through second hole 204. By attaching cleaning tip 206 to patch 200 through hole 204, a greater portion of patch 200 can trail cleaning tip 206 when in a gun barrel, thereby reducing the effective diameter of the cleaning tip 216 and patch 200 combination.
It will be noted that this invention fully meets the objectives set forth. A gun barrel cleaner capable of withstanding high pulling stresses yet versatile enough to clean a wide range of gun barrels quickly and efficiently is provided. Further, a compact container is provided for convenient storing and transporting of such a gun barrel cleaner. Lastly, it will be observed that the improved method of attaching a gun cleaning patch to a gun cleaning tip having a patch receiving slot therein allows for a more efficient cleaning of a gun barrel.
Although several embodiments have been illustrated in the accompanying drawings and described in the foregoing detailed description, it will be understood that the invention is not limited to the embodiments discussed but is capable of numerous rearrangements, modifications, and substitutions without departing from the scope of the invention. For example, various cleaning tips, such as brushes, swabs, etc., may be used in combination with the gun barrel cleaner. Other changes, within the scope of the invention as defined by the appended claims, will suggest themselves to those skilled in this art.
