A firearm barrel cleaning shell including a casing carrying a primer at one of its ends and having an opening at the other of its ends. A blast conduit is positioned within the casing so as to receive the discharge from the primer and to direct the discharge toward the opening in the casing. A projectile is positioned within the casing and includes an ejectable plug that, before the discharge of the primer, closes the opening in the casing. A flexible tether connects the plug to an oil-saturated pad is positioned adjacent the primer and a solvent-saturated pad positioned between the plug and the oil-saturated pad.
Description
- The present invention relates generally to ammunition and explosives and, more particularly, to cartridges with bore cleaning means.
- Cleaning the barrel of a firearm has never been easy. Typically, long-handled brushes and similar tools carrying powerful solvents are used to manually scrub the internal surface of a firearm barrel. Afterward, oil is placed in the barrel to inhibit corrosion and excess oil is wiped up to prevent marring of the gunstock. The process can be tedious and time-consuming and, if poorly performed, can result in the premature deterioration of the firearm. In extreme cases, the firearm can be rendered inoperative.
- In light of the problems associated with the known methods and apparatus for cleaning the barrels of firearms, it is a principal object of the invention to provide a firearm barrel cleaning shell that can quickly and effectively clean the barrel of a firearm. The shell is intuitive to use and can be employed with minimal training and without resort to additional tools.
- It is an object of the invention to provide improved elements and arrangements thereof in a firearm barrel cleaning shell for the purposes described which is lightweight in construction, inexpensive to manufacture, and dependable in use.
- Briefly, the firearm barrel cleaning shell in accordance with this invention achieves the intended objects by featuring a casing adapted for positioning within the firing chamber of a firearm. The casing carries a primer at one of its ends adapted to explosively discharge gases upon being struck by the firing pin of a firearm and has an opening at the other of the ends. A blast conduit is centrally positioned within the casing defining an annulus between the blast conduit and the casing. The blast conduit has an inner end positioned about the primer so as to receive the discharge from the primer and, also, has an outer end in fluid communication with the inner end for directing the discharge from the primer toward the opening in the casing. A projectile is positioned within the casing and includes an ejectable plug that closes the opening in the casing. A pair of flexible tethers connects the plug to an oiling pad positioned within the annulus adjacent the primer and a number of cleaning pads positioned within the annulus between the plug and the oiling pad.
- The foregoing and other objects, features and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.
- The present invention may be more readily described with reference to the accompanying drawings, in which:
-
FIG. 1 is a side view of a firearm barrel cleaning shell in accordance with the present invention. -
FIG. 2 is a longitudinal cross-sectional view of the firearm barrel cleaning shell ofFIG. 1 . -
FIG. 3 is a side view of a portion of a barrel of a firearm with the projectile of the firearm barrel cleaning shell being discharged therefrom. -
FIG. 4 is a perspective view of the projectile of the firearm barrel cleaning shell with portions broken away. - Similar reference characters denote corresponding features consistently throughout the accompanying drawings.
- Referring now to the FIGS., a firearm barrel cleaning shell in accordance with the present invention is shown at 10. Shell 10 includes a
casing 12 supporting aprimer 14 at one of its ends and having an opening 16 at the other of its ends. Ablast conduit 18 is centrally positioned withincasing 12 to receive the discharge fromprimer 14 and to direct the discharge toward opening 16. Aprojectile 20 is positioned withincasing 12 and has anejectable plug 22 initially closing opening 16.Plug 22 is joined by a pair oftethers 24 to anoiling pad 26adjacent primer 14. A number ofcleaning pads plug 22 andoiling pad 26. When struck by a firing pin,primer 14 explosively discharges gases intoconduit 18 and, viaconduit 18, againstplug 22 with sufficient force to expelprojectile 20 fromcasing 12. -
Casing 12 has anend cap 30 from which atube 32 extends.End cap 30 includes acircular base plate 34 having a central aperture 36 within whichprimer 14, being a small tube containing explosive typically for firing the main charge of a big gun, is affixed. Aretaining sleeve 38 is integrally formed with the periphery ofbase plate 34 and surroundsprimer 14 at a distance. The inner end oftube 32 is tightly wedged withinsleeve 38 and the outer end thereof is remote fromplate 34. The outer end oftube 32 is provided with an inwardly projectinglip 40 about its periphery that defines opening 16. -
Conduit 18 comprises ahollow cylinder 42 having an integral stabilizinghoop 44 at one end ofcylinder 42.Cylinder 42 has a diameter sufficient to snugly receiveprimer 14 within one of its ends and to define anannulus 46 between itself andtube 32. Preferably, the inner end ofcylinder 42 havinghoop 44 rests againstplate 34 and receivesprimer 14 therein and the outer end ofcylinder 42 engagesplug 22. The periphery ofhoop 44 presses tightly against the inside oftube 32 to ensure thattube 32 cannot exitcasing 12 upon discharge ofprimer 14 and the passage ofprojectile 20 fromcasing 12. -
Plug 22 is a plastic disk sized to fit snugly within the outer end oftube 32. As shown, plug 22abuts lip 40 and, prior to discharge ofprimer 14, is retained bylip 40 withintube 32. Upon discharge ofprimer 14, the center ofplug 22 is hit by primergasses exiting conduit 18 slightly deforming bothplug 22 andlip 40 permittingplug 22 toexit tube 32 through opening 16. -
Oiling pad 26 includes awiper ring 48 to which is bonded anoil applicator ring 50.Wiper ring 48 is formed of impermeable plastic and is initially positioned withinannulus 46 abuttinghoop 44.Wiper ring 48 is dimensioned to snugly, yet slidably, engagetube 32 along the outer surface ofwiper ring 48 and conduit 18 along the inner surface ofwiper ring 48.Applicator ring 50 is adhesively fastened to the side ofwiper ring 48 facing opening 16 and is separated fromhoop 44 bywiper ring 48.Applicator ring 50, likewiper ring 48, is dimensioned to snugly, yet slidably, engagetube 32 and conduit 18.Applicator ring 50 is formed of tightly compacted organic or inorganic fibrous material and is saturated with oil of a kind suitable for treatingbarrel 52 offirearm 54. - Each of cleaning pads 28 a-28 d includes a
wiper ring 56 having asolvent applicator ring 58 bonded thereto. Eachwiper ring 56 is formed of impermeable plastic and is positioned withinannulus 46 betweenplug 22 andoiling pad 26. Eachwiper ring 56 is dimensioned to snugly, yet slidably, engagetube 32 along the outer surface thereof and engageconduit 18 along the inner surface thereof. Anapplicator ring 58, however, is adhesively fastened to the side of eachwiper ring 56 facing opening 16. Eachapplicator ring 58 is dimensioned to snugly, yet slidably, engagetube 32 and conduit 18. Eachapplicator ring 58 is formed of tightly compacted organic or inorganic fibrous material and saturated with solvent of a kind suitable for cleaningfirearm barrel 52. -
Tethers 24 are lengths of string positioned withinannulus 46 midway betweentube 32 andconduit 18 and 180° apart.Tethers 24 extend from one end ofcylinder 42 to the other end and their opposite ends are affixed in a suitable manner to plug 22 andwiper ring 48. Additionally,tethers 24 are affixed to each ofwiper rings 56. - A pair of
tether segments 24 a connectplug 22 to cleaningpad 28 d. Prior to the discharge ofprimer 14,segments 24 a are coiled side-by-side withinannulus 46 and serve as spacers betweenplug 22 andcleaning pad 28 d.Segments 24 a have a length sufficient to permitplug 22 to travel to the end offirearm barrel 52, i.e., about eight times the length ofcasing 12, upon discharge ofprimer 14 without pulling upon or moving any ofpads 26 or 28 a-28 d thereby ensuring the highest possible acceleration and initial velocity ofpads 26 and 28 a-28 d throughbarrel 52. - A pair of
tether segments 24 b connects each ofpads 26 and 28 a-28 d together in the manner of a train. Prior to the discharge ofprimer 14,segments 24 b are coiled side-by-side withinannulus 46 and serve as spacers betweenpads 26 and 28 a-28 d.Segments 24 b have a length that permits fluid from each one ofpads 26 and 28 a-28 d to contactbarrel 52 for a period of time that maximizes the cleaning ofbarrel 52 before such is wiped a way by a trailing one of the pads, i.e., about two times the length ofcasing 12. - The use of firearm
barrel cleaning shell 10 is straightforward. First,shell 10 is loaded intobarrel 52 in a conventional matter. Then, withbarrel 52 pointed in a safe direction, the trigger offirearm 54 is pulled so as to cause a firing pin to contactprimer 14. The impact of the firing pin uponprimer 14 causesprimer 14 to explosively discharge gases intoconduit 18. The gasses are conveyed to plug 22 that is, then, driven forcefullypast lip 40 and from opening 16. Now, plug 22 travels downbarrel 52drawing tether segments 24 a behind it. Whenplug 22 reaches the end ofbarrel 52 and all slack is taken fromtether segments 24 a,cleaning pad 28 d is pulled downbarrel 52. A thin film of solvent is applied byapplicator ring 58 ofcleaning pad 28 d along the length ofbarrel 52 with any solvent residue being immediately drawn frombarrel 52 bywiper ring 56 ofcleaning pad 28 b. The barrel cleaning process is repeated as cleaningpads pad 28 d downbarrel 52 each being pulled by the momentum ofplug 22 conveyed throughtethers 24. Thus, in a process akin to obtaining a smooth shave with a multi-blade razor, each cleaning pad 28 a-28 d scrubsbarrel 52 more than the one that preceded it downbarrel 52 resulting in maximum cleaning. - Oiling
pad 26 serves as a caboose to the train formed byplug 22 and cleaning pads 28 a-28 d. Being pulled bytethers 24 downbarrel 52,applicator ring 50 deposits a thin film of oil along the length ofbarrel 52 with oil residue being drawn frombarrel 52 bywiper ring 48.Projectile 20 having passed throughbarrel 52 and dissipating all of its energy can be picked up and discarded properly.Casing 12, now absent projectile 20, can be removed fromfirearm 54 and similarly discarded. - With
barrel 52 being cleaned and oiled,firearm 54 can be stored in a safe and dry location for subsequent reuse without fear of undue corrosion. No additional applications of cleaning compositions or oils are necessary. The entire cleaning and oilingprocess using shell 10 requires only seconds to complete. - While
shell 10 has been described with a high degree of particularity, it will be appreciated by those skilled in the art that modifications may be made thereto. For example, the number of oiling andcleaning pads 26 and 28 a-28 d might be increased or decreased as a manufacturer sees fit to tweak the oiling and cleaning properties ofshell 10. Therefore, it is to be understood that the present invention is not limited to the single shell embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
