BARREL CLEANER SHELL FOR FIREARMS Filed May 15 1964.
BYQ'DCV AT QRNEY# United States Patent O 3,209,690 BARREL CLEANER SHELL FR FIREARMS Clarence G. Mercatoris, Jr., 940 Beachwood Drive, Meadville, Pa. Filed May 15, 1964, Ser. No. 367,650 6 Claims. (Cl. 102-39) This invention relates to shells for cleaning the bores of firearm barrels, and more particularly to a shell for cleaning the bore of 'a relatively large bore rearm, such as a shotgun and the like.
It is one of the objects of this invention to provide such an improved cleaning shell for shot guns and the like which is substantially of .the same size and shape as a standard shotgun shell.
It is another object of the invention to provide an improved barrel cleaning shell which is simple and inexpensive in its construction, and yet at the same time, efcient and effective in its use in loosening and in cleaning the burnt powder and rust from the barrel.
lIt is a more specic object of the linvention to provide such an improved cleaning shell for Shotguns and the like wherein there is provided a projectile in the shell casing having a liquid container arranged therewith which when propelled through the bore of the gun permits the liquid in the container to be expelled to the peripheral surface of the bore with a quantity of cleaning material arranged in the shell rearwardly of the container which is moved through the bore of the barrel after the propelling powder charge has passed through the bore so as' to leave the bore in a clean c-ondition.
Various other objects and advantages of this invention will be more apparent in the course of the following specification, and will Ibe particularly pointed out in the appended claims.
In the accompanying drawings, there is shown for the purpose of illustration an embodiment which the invention may assume in practice.
In these drawings:
FIG. 1 is a side elevational view of the improved barrel cleaning shell constructed in accordance with the present invention,
FIG. 2 is a sectional view taken on line 2 2 of FIG. 1,
FIG. 3 is a sectional view taken on line 3 3 of FIG. 2,
' FIG. 4 is asectional view taken on line 4 4 of FIG. 2, and
FIG. 5 is a sectional view taken on line 5 5 of FIG. 2.
Referring more particularly to the drawings, the improved barrel cleaning shell in accordance with the present invention has the size, shape and general appearance of an ordinaryvshotgun shell and consists of a cylindrical hollow casing 2 formed of paper or other suitable mate- -rial having a cap or head 3 secured to one or the inner end thereof so as to close this end of the casing, and a primer 4 extending axially through the cap or head 3 into the interior of the casing. Within the casing directly next to the inner side of the cap or head 3, there is positioned a conventional circular wad or pad 5 having an aperture axially thereof into which the primer 4 extends.
There is also mounted within the casing 2, an elongated hollow plastic tubular member 6 having an enlarged substantially frusto-conical shaped head portion 7 at one end thereof which is positioned directly next to the Wad or pad 5 therein. Also within the casing adjacent the outer end of the shell there is arranged a cup-like container member 8, preferably made from some suitable plastic material, having a closed inner wall, as at 9, and a hollow cylindrical axial portion 10 into and through which the outer end of the plastic tube extends. At the outer end of the shell and within the casing, there is mounted a weighted assembly 12 in the form of a circular washer or disc of metal which is disposed directly next to the open 3,209,690 Patented Oct. 5, 1965 ICC end of the cap-like member 8 and which acts as a cap therefor and as the head of the lead projectile 13 which is dispos-ed in the outer end of the plastic tube 6.
Within :this cup-like member S, there is arranged a pair of nylon ejection cords 14 having one end thereof attached to the inner side of this weighted assembly 12, as
at 15, and the opposite end attached to the inner side of the closed inner wall 9, as at 16. On the inner side of the closed inner Wall 9, there is arranged extension 17 which acts as a locking device for assembly of projectile head and cup after compressed bore cleaning material has been disposed around tubular member 6 which is attached, as at 18, to the outer side of the elongated plastic tube `6 so as to move therewith in Ia manner presently to be described.
In the cup-like member 8, there is disposed preferably a cleaning liquid 19, such as a solvent or rust inhibitor, with the cords 14 loosely coiled and immersed therein, as shown in FIG. 2 of the drawings. In the space around the tubular member 6 between the same and the wall of the casing and inwardly of the frusto-conical portion 7, there is disposed a quantity of suitable compressed bore cleaning material 20, such as ordinarily employed in the wadding of shot gun shells. This cleaning material is preferably of cotton waste, felt material, or other suitable material, with or without oil, or an abrasive, as may be desired, which is packed in the shell 4casing around the tubular member 6 and between the same and the inner periphery of the shell casing to a highly compressed degree, so that it remains in the shell on the initial explosion thereof lbut will freely expand within the barrel on propulsion of the projectile through and out of the barrel. Within the tubular member 6, directly opposite the primer 4 and in the space between the same and the inner end of the lead projectile 13 there is disposed a powder charge 21.
Having described the construction of my improved barrel cleaning shell, it functions in the following manner. It will be understood that the shell, as shown in FIG. 1, is positioned in the shell chamber of the gun barrel the same as an ordinary shell is positioned therein. With the cleaning shell thus positioned in the shell chamber of the gun barrel, when the powder charge 19 is tired, the explosion of the powder will act on the inner end of the projectile 13, thereby driving it together with the weighted assembly '12 through the bore of the gun barrel. Such movement will result in the uncapping of the cap-like member 8 and permit the liquid 19 therein to escape therefrom and flow into the bore of the barrel.
Upon continued movement of the weighted assembly 12 the slack in the ejection cords 14 will be gradually taken up and as the weighted assembly moves out of the muzzle end of the gun barrel these cords 14 will be fully stretched and upon continued movement of the weighted assembly, these cords will pull the cap-like member 8 together with Ithe tubular member 6 to which it is attached from the shell casing 2 and through the bore of the gun. In such movement of this it will be seen that the cleaning material 20 will be pushed through the bore by the frusto-conical portion 7 of the tubular member and this cleaning material will thoroughly scrub the inner surface of the gun barrel and remove therefrom all foreign material, such as rust and burned powder.
It will be understood that the two cords 14 should be of such length when stretched .as to ensure that all powder and gases of explosion are completely burned and spent before the inertia of the lead projectile pulls the tubular member 6 through the barrel.
`As a result of my invention it will be seen that there is` provided an improved cleaning shell by means of which the bore of a gun can be satisfactorily cleaned quickly and easily without the need of oil, cleaning rods and rags usually employed for such purposes. It will also be seen that this cleaning shell is so constructed and arranged as to render it very effective for the purpose intended and can be conveniently used in the eld immediately after the gun has been exploded.
While there is shown and described an embodiment which the invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised within the scope of the invention as defined in the appended claims.
