These members 11 and 12 on opposite ends of the spring senve another function in addition to the cleaning function when the spring 10 is in its straight end to end position in Fig. l. Since the spring is laterally bendable, the spring may be coiled into a compact form for carrying. However, it is desirable to have means provided on the cleaner for detachably connecting together the opposite ends thereof so that the cleaner not only Will form a compact package for carrying but also prevent the danger of having the end ung dangerously outwardly by the release of the spring. This latter action would not only prevent convenient carrying but also subject the hunter to the danger of physical harm by the spring driven members 11 and 12. Therefore, after the spring 10 has been coiled together, the ends thereof are wrapped around or interlocked with the coiled form, and then the ends of the members are detachably connected together to assume the Fig. 2 position for convenient and safe carrying in the eld until barrel cleaning is required.

The ends are detachably but rmly secured together by eye 11a of member 11 and any eye engageable portion on the opposite end of spring 10, such as a hook or even an elongated portion like a length of Wire or a cylindrical cleaning tip with an enlarged head, as brought out in more detail in the next paragraph. In the present disclosure, this portion is located on the outer end of the brush '12. Here, the component wires 12a and 12b of the brush are formed from a single length of wire twisted upon itself with an end loop 12e being integrally formed at the outer end thereof. A portion 12d is notched out of this loop so that it forms a resulting hook for detachable engagement with the eye 11a.

However, this portion need not be formed by a clearly bent hook on the end of the barrel brush member 12. For example, the left end of the spring 10 in Fig. 1 may have a projection thereon detachably engageable with the eye 11a so that the cleaner has only the one member 11 thereon for barrel cleaning. Alternatively, the member 11 may be omitted and the eye or a suitable hook may be formed from the last coil of the spring 10 on the right-hand side thereof for detachable engagement with the portion on the end of the brush. Also, if the neck of member 11 between eye 11a and threads 11b or the neck behind the enlarged head on the other type patch cleaner is suciently small in diameter, it may be inserted through gap 12d into hook engagement; also, if the enlarged end is suiciently small on any of these type patch holders, it may be inserted into the bore of loop 12e even though notch 12d has not been cut. Also, the por tion on the end of the brush need not be bent into a clear hook shape. For example, one or both of the Wires 12a, 12b may extend axially and straight beyond the end of the brush bristles 12e to form a portion detachably engageable with the eye 11a and held in position by the resilient spring 10 tending to uncoil the cleaner from the Fig. 2 to the Fig. 1 position. Many other forms of this invention will be readily `apparent to anyone skilled in the art and it should be clearly understood that any form of member, serving as at least a portion of a barrel cleaning member could be used at each end of the spring 10 but we prefer `and have found most satisfactory results obtainable with the structure disclosed herein. Also, the cleaning patch may be held in any suitable structure during rifle cleaning, whether it be eye 11a, hook 12e or an eye or loop formed by wire 12e without notch 12d.

After the cleaner has assumed the position in Fig. 2, it should be readily understood that the whole unit can be put into -a pouch 13 being formed of lcloth, plastic, or other suitable material and having an envelope portion 13a closed except for an open top which may be closed by a bendable flap 13b and then locked in position by a snap fastener 13C being connected to the front wall of the envelope 13a. This pouch 13 may be easily carried in the pockets during hunting.

If desired, a detachable clip can be wrapped around the coils of spring 10 at the upper right in Fig. 2, opposite the bore cleaning members 11 and 12, but we have found that this is not necessary when the members are properly formed for the detachable engagement of the opposite ends of the gun barrel cleaner.

Whenever the rie or shotgun bore becomes obstructed in the field, the hunter can quickly and easily remove the pouch 13 from his pocket, remove the gun barrel cleaner from the pouch, detach hook 12C from eye 11a, unwind the interlocked ends of the spring 10 and then carefully uncoil the spring so that the gun barrel can be readily used by either pushing through or pulling through the gun barrel bore. The cleaner assumes a straight end to end position, as shown in Fig. 1, but either the barrel cleaning brush member 12 or the member 11, adapted to carry a cleaning patch for barrel cleaning, is readily usable for cleaning the barrel. Spring 10 is substantially unyieldable in at least one axial direction and preferably in both axial directions so that it will have suicient stiffness for the cleaning operation. When the hunter is finished cleaning his gun, he merely reverses the above-mentioned operation and then inserts pouch 13 in his pocket for convenient carrying While he continues the hunt.

It has been found desirable to quickly and efficiently attach the members 11 and 12 to the opposite ends of spring 10 in an inexpensive manner. Both of the members have identical male threads formed on the spring end thereof with member 11 having threads 11b formed integrally thereon while brush 12 has an adaptor 15 with male threads 15a on one end and a sleeve 15b on the other end telescoped over and secured to the end of the twisted wires 12a, 12b.

Since both threads 11b and 15a are identical, only one need be described, for example threads 11b. The thread has for proper interlock the same hand as the spring helix, in other words, the helix of the spring and the helix of the threads are both advancing in the same direction. The inside diameter of the spring is approximately 0.004-0.005 inch larger than the outside diameter of the thread. The thread 11b is telescoped into the bore of the spring 10 within a half spring coil short of the end of the thread. Then, the unit is heated to about 480 Fahrenheit for about twenty minutes so that the steel spring will creep forwardly to its nished position at the end of the thread and then will firmly grip the thread so that the member 11 is not easily removed therefrom. It is frequently necessary to use a Spanner wrench or equivalent to remove each member from its securing engagement with the bore of spring 10. Although other methods of manufacture may be used, we have found this to be the preferred method.

This gun barrel cleaner' can of course be made in different outside diameters sc that each one will be especially designed for one particular rifle caliber, shotgun gauge, or other ire arm bore size.

Also, a modified form of member 11 may be used. The member 11 in Fig. l is machined from a solid piece of stock pierced to form the eye Iwhile the modified form of member 121 in Fig. 3 is formed `from one continuous and integral length of spring wire wound into the form of a spring 11b with the right end thereof extended toward the right and bent back on itself to form eye 11a with its distal end extending between spring coils 11b. This member 11 is usable in the same manner as a cleaning patch tip or tip patch cleaner. Also, the spring 11b' forms a thread on its periphery with the same hand as the helix of spring 10 with an outside diameter substantially the same as thread 11b. Hence spring lib can in the same manner be threaded in the direction of the arrows into the bore of spring 10 and heated to cause creeping to secure the parts together.

Various changes in details and arrangement of parts can 4be made by one skilled in the art without departing from either Vthe spirit of this invention or the scope of the appended claims.
