1 Claim.

This invention relates to improvements in de vices for cleaning, lubricating and sealing barrels of guns.

In the use of fire arms, it is important after use to keep the bore of the gun barrel clean and well lubricated. It is also desirable to have means which will prevent the entrance of moisture or humid air into the bore while the gun is in storage or not in use so that rust will not occur.

It is a general object of the present invention to provide a single, relatively simple instrumentality, which can be inserted into the barrel of the gun when the gun is not in use to perform all three important functions of cleaning, lubricating and sealing.

A further object of the invention is to provide a device as above described, including a cleaning brush and one or more lubricating and sealing rolls wherein any of said members may be easily and quickly renewed after they have become worn.

A further object of the invention is to provide a devicefor cleaning, lubricating and sealing the barrels of guns wherein there is means projecting from one end of the gun bore, when the device is in use, for facilitating withdrawal of the device when required, the said means being quickly detachable so that the stock of the gun ma be reassembled with the barrel if desired, leaving the cleaning and sealing device in position.

Other objects of the invention are to provide a device of the class described which can be used either with barrels having tapered bores 01' with barrels having straight bores; to provide a device which, when in place, prevents the insertion of shells and therefore acts as a safety when the gun is being transported or stored; and to provide a device which is relatively inexpensive to manufacture.

With the above and other objects in view, the invention consists of the improved device for cleaning, sealing, and lubricating the barrels of guns, and all its parts and combinations, as set forth in the claim, and all equivalents thereof.

In the accompanying drawing, illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals designate the same parts in all of the views:

Fig. 1 is a side view showing the device in sealing position in the barrel of a gun, the barrel being illustrated in longitudinal section;

Fig. 2 is a fragmentary view on an enlarged scale at the outer end of the device, parts being 2 broken awa and shown in longitudinal section;

Fig. 3 is a fragmentary view of the inner end of the device, parts being broken away and shown in longitudinal section;

Fig. 4 is a side view of one of the brush holding studs;

Fig, 5 is a side view of the other brush holding stud; and

Fig. 6 is an outer end view of the improved device.

Referring more particularly to the drawing, the gun barrel is indicated by the number Ill. The barrel illustrated has a bore II, which is tapered slightly in an outward direction. It is to be understood, however, that the invention is equally applicable for use in connection with guns having straight bores.

The improved device with which the present invention is concerned includes a straight metal rod I2 having its outer end threaded as at I3, and also having its inner end threaded as at l4.

The rod is inserted through the longitudinal bores I5, I6 and ll of rolls I8, I9 and 23. These rolls may beformed of felt or any material capable of being impregnated with a lubricant and having the flexibility and cushioning characteristics necessary for the purpose. While the device will perform its function with only one roll on the rod I 2 located in the position of the roll it, nevertheless the, efficiency is improved materially by utilizing more than one roll such as the three rolls illustrated.

The roll I8 is removabl retained in position by means of end washers 2| and 22 which are in turn held by cotter pins 23 and 24 extending through cotter pin holes in the rod I2.

The r011 I 9 is similarly removably held in position by means of end washers 25 and 26 and cotter pins 21 and 28. Roll 23 is restrained against longitudinal movement in one direction by washer 29 and cotter pin 3|], and against movement in the other direction by a washer 3| held in place by a connection member 32, which is screwed onto the threaded end I 3 of the rod.

At the inner end of the device there is a cap nut 33 threaded on the end I 4 of the rod I2. The nut has a transverse bore 34 within which a finger ring 35 is inserted.

The connection member 32 has its outer end formed with a threaded bore 35 for receiving the threaded stem 37 of a brush holding stud 38. The latter has its outer end inwardly slotted as at 39 to receive the lo'oped end 40 of the wire core M of brush 42. The looped end 40 may be frictionally squeezed in position in the slot 39. The

3 other end of the brush is formed with a loop 43 which is similarly held in a slot 44 of a brush holding stud 45. The stud 45 has its outer end of reduced diameter to form an intermediate shoulder 46. A washer 41 may be placed on the outer end of the stud 45, and then the outer end of the stud may be inserted into the bore portion 48 of a relatively short sealing roll 49. The roll 49 is formed of material similar to the rolls l8, I9 and 20. The bore portion 48 terminates at a point intermediate the length of the roll 49 and joins a smaller bore 50. A screw 52 inserted from the outer end through the bore 50 is threaded into a threaded bore portion 5| at the outer end of the stud 45 to removably hold the parts 49 in position. The roll 49 is also impregnated with a lubricant.

After a gun has been used it is broken open to expose the inner end 53 of the bore. The improved device is then inserted into said end to the position illustrated in Fig. 1. The rolls I8, I9, 20 and 49 and the brush 42 have an external diameter which is slightly larger than the bore of the gun with which they are to be used. There is suflicient flexibility in the members, however, to permit manipulation While providing for a snug fit into either a tapered bore or a straight bore. 1

As the device is being inserted, the various portions of the bore will be lubricated by the rolls 49, 20, I9 and I8, and the brush 42 will perform a cleaning operation. When the gun is to be put away in storage, the device is left in the position shown in Fig. 1, with the outer end of the roll 49 flush with the outer end of the barrel; thus entry of moisture into said end is prevented. In addition, the device is of such length that when the roll 49 is located as in Fig. 1, the roll I8 is located close to the inner end of the barrel to prevent the entrance of moist air into any part of said end where it could do harm. The device may be manipulated by using the finger ring 35. However, if it is desired to reassemble the gun with the sealing device in position, then the ring may be unthreaded from the rod end l4. When this has been performed, there is nothing projectin beyond the inner end of the bore to prevent reassembling the stock on the barrel. While the gun is thus stored, the use of the sealing device is insurance against the presence of a shell in the barrel. Thus the gun cannot he accidentally discharged.

The brush 42 can be quickly replaced when required by unthreading the stud 38 and screw 52 and replacing with a new brush equipped with 4 new studs 38 and 45, or a new brush may be inserted in the slots 39 and 44 of the old studs. In addition the construction is such as to permit quick removal and replacement of any of the rolls l8, I9, 20 and 49.

Various changes and modifications may be made without departing from the spirit of the invention, and all of such changes are contemplated as may come within the scope of the claim.

What I claim as the invention is:

In a device for cleaning and oiling guns, a cylindrical brush having a first wire loop at one end and a second wire loop at the opposite end; a first stud projecting axially of said brush and formed at one end with a diametric slot in which said first loop is removably positioned and being formed at its other end with external screw threads; 2. second stud projecting axially of said brush and formed at one end with a diametric slot in which said second loop is removably positioned and being formed at its other end with a portion of reduced diameter, said reduced portion being formed in its outer end with a threaded axially extending aperture; an axially bored cylindrical roll of relatively soft compressible material positioned on the reduced portion of said second stud; and a screw extending through the bore of said roll and having a portion removably positioned in the threaded aperture of the second stud for holding said roll in position on said stud.
