A firearm barrel cleaning cartridge that includes a hollow, cylindrically-shaped, closed back, and open front shell casing, at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper, a propellant, and at least one wad. The hollow, cylindrically-shaped, closed back, and open front shell casing contains an internal chamber. The at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper is contained laterally in the hollow, cylindrically-shaped, closed back, and open front shell casing and divides the internal chamber into a plurality of internal sub-chambers. The propellant is contained in a first internal sub-chamber of the plurality of internal sub-chambers. And, each wad is contained in a respective sub-chamber of each at least one remaining sub-chamber of the plurality of internal sub-chambers, so that when the propellant is activated the at least one wad exits therefrom alternatingly with the at least one expandable, generally hemispherically-shaped, rearwardly-facing, and removable wiper and thereby alternatingly cleaning, wiping, and expelling unwanted debris from an interior surface of a barrel of a typical firearm through a muzzle thereof.

BACKGROUND OF THE INVENTION 
The present invention relates to a firearm barrel cleaning cartridge. More 
particularly, the present invention relates to a firearm barrel cleaning 
cartridge that includes a hollow, cylindrically-shaped, closed back, and 
open front shell casing, at least one expandable, generally 
hemispherically-shaped, rearwardly-facing, and removable wiper that is 
contained in the hollow, cylindrically-shaped, closed back, and open front 
shell casing, a propellant that is contained in the hollow, 
cylindrically-shaped, closed back, and open front shell casing, and at 
least one wad that is contained in the hollow, cylindrically-shaped, 
closed back, and open front shell casing and alternating with the at least 
one expandable, generally hemispherically-shaped, rearwardly-facing, and 
removable wiper. 
The discharge of conventional firearms results in deposits of residue on 
the inside surface of the bore of the firearm. Such deposits, over time, 
can damage the firearm, impair its performance, and lead to potentially 
dangerous conditions. 
The cleaning of the bore of a firearm by conventional means is a tedious 
process wherein cleaning wads attached to rods are doused with cleaning 
solution and run through the bore. Such conventional cleaning is not 
conveniently effected during hunting trips or tournaments, because of the 
time involved and the extra hardware which must be carried by the operator 
of the firearm. 
Projectiles constructed to clean the barrel of a gun typically have 
included scrapers and cleaning elements. Generally, the scraper is 
arranged on the projectile in advance of the cleaning element for the 
purpose of loosening the burnt powder or rust from the wall of the bore, 
so that this dirt or foreign material can be carried out of the barrel by 
the cleaning element when the projectile is fired. It has been found, 
however, that these scrapers often do not adequately loosen the gunpowder 
residue and rust, which then renders the cleaning element essentially 
ineffective. 
Further, muzzle flash and gun barrel erosion are two phenomena which have 
caused serious problems with past and present guns. Moreover, these 
problems hinder the development of new energetic gun systems. In an effort 
to these problems, it has been conventional to use selective additives too 
reduce flash and erosion of gun barrels. The success of these additives, 
however, have been system limited because of the problems of packaging the 
additives in the propelling charge. 
Gun barrel erosion has been described, e.g., in "A Study of the Erosion 
Process Using several Group IV Oxides" by Linchitz, C. and Silvesto, G. 
Tech Report No. 1869, Picatinny Arsenal, Dover, N.J., December 1968. 
Frequently, the packaging of these additives in the propelling charge is an 
extremely difficult, if not almost insurmountable, feat. It is known, for 
example, to incorporate relatively benign erosion and flash additives, 
such as TiO.sub.2, talc, K.sub.2 SO.sub.4, KNO.sub.3, in a wax cloth liner 
if there is sufficient space in the propellant charge. Sometimes, however, 
space in the propelling charge is at a premium, and introduction of these 
benign additives in the proper configuration cannot be readily achieved. 
Also, with more volatile flash reducers, such as (NH.sub.4).sub.2 
CO.sub.3, NH.sub.4 HCO.sub.3, and KHCO.sub.3, this cannot be accomplished 
because the temperature required to melt the wax also results in 
volatization of these additives. 
Placement of some of these additives in the propelling charge without 
proper protection is also unsatisfactory because even at room temperature, 
sublimation occurs which causes a total loss of flash reducer over a 
extended period of time. One solution to this space problem has been to 
package the additives in a non-permeable plastic bag. There is often 
insufficient space, however, in the propelling charge for the bag of 
additives. 
Numerous innovations for tube cleaning devices have been provided in the 
prior art that will be described. Even though these innovations may be 
suitable for the specific individual purposes to which they address, 
however, they differ from the present invention in that they do not teach 
a firearm barrel cleaning cartridge that includes a hollow, 
cylindrically-shaped, closed back, and open front shell casing, at least 
one expandable, generally hemispherically-shaped, rearwardly-facing, and 
removable wiper that is contained in the hollow, cylindrically-shaped, 
closed back, and open front shell casing, a propellant that is contained 
in the hollow, cylindrically-shaped, closed back, and open front shell 
casing, and at least one wad that is contained in the hollow, 
cylindrically-shaped, closed back, and open front shell casing and 
alternating with the at least one expandable, generally 
hemispherically-shaped, rearwardly-facing, and removable wiper. 
FOR EXAMPLE, U.S. Pat. No. 5,151,557 to Bracuti et al. teaches a propelling 
charge additive that includes a propellant charge, a propellant-containing 
bag or propellant-containing container which is coated with a composition 
for reducing muzzle flash and bun barrel erosion. The composition includes 
sodium or potassium water glass and a volatile flash suppressant of 
NH.sub.4 HCO.sub.3, (NH.sub.4).sub.2 CO.sub.3 and/or KHCO.sub.3. 
ANOTHER EXAMPLE, U.S. Pat. No. 5,170,524 to Vowles teaches a projectile 
launcher that is adapted for use in an apparatus for cleaning tubes that 
is arranged in the apparatus of the type whereby a projectile is placed in 
a tube to be cleaned and then subjected to a sudden cleaning medium 
pressure impact to force the projectile through the tube at high speed. 
STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,233,128 to Lai teaches a barrel 
cleaning bullet that contains a charge of cleaning fluid and an array of 
cleaning elements that extend about the exterior surface of the bullet. 
Upon firing of the bullet, a piston, slidably positioned in the cavity 
filled by the fluid, forces the fluid through at least one discharge port 
formed in the head of the bullet. 
FINALLY, YET ANOTHER EXAMPLE, U.S. Pat. No. 5,341,744 to Shi teaches an 
apparatus for cleaning the bore of a firearm that includes a shell housing 
having a rearwardly oriented base portion, a substantially tubular body 
defining a cavity, and a forward end, a tank for confining a compressed 
fluid. The tank is disposed within the cavity of the housing. A cleaning 
wad for cleaning the bore of the firearm is disposed forward of the tank. 
And, a rupturing member is disposed between the tank and the cleaning wad. 
It is apparent that numerous innovations for tube cleaning devices have 
been provided in the prior art that are adapted to be used. Furthermore, 
even though these innovations may be suitable for the specific individual 
purposes to which they however, they would not be suitable for the 
purposes of the present invention as heretofore described.

however, only the expandable, generally hemispherically-shaped, 
rearwardly-facing, and removable first wiper 36 is shown but it is to be 
understood that the remaining five wipers have the identical configuration 
thereto. 
The shell casing internal chamber first internal sub-chamber 32 of the

closed back, and open front shell casing 16 is filled with a shell casing 
internal chamber fifth internal sub-chamber removable wad 72 that is also 
preferably made of fiber, cotton, or jute. 
The shell casing internal chamber sixth internal sub-chamber 58 of the 
shell casing internal chamber 17 in the hollow, cylindrically-shaped, 
closed back, and open front shell casing 16 is filled with a shell casing 
internal chamber sixth internal sub-chamber removable wad 74 that is also 
preferably made of fiber, cotton, or jute. 
The shell casing internal chamber second internal sub-chamber removable wad 
66 of the shell casing internal chamber second internal sub-chamber 34 of 
the shell casing internal chamber 17 in the hollow, cylindrically-shaped, 
closed back, and open front shell casing 16 can be impregnated with a 
shell casing internal chamber second internal sub-chamber removable wad 
impregnated muzzle flash and barrel erosion reduction composition 76. 
It has been, surprisingly, discovered that muzzle flash and gun barrel 
erosion can be reduced by an aqueous solution of a water glass. Typical 
suitable water glasses comprise Na.sub.2 O.sub.x SiO.sub.2 or K.sub.2 
O.sub.x SiO.sub.2 or mixtures thereof, wherein x is 3-5. 
The water glass is particularly advantageous because it is soluble in an 
aqueous solution. Preferably, the aqueous solution contains from 5%-40%, 
more preferably from about 5%-20% by weight of the water glass. The 
solution can also contain small quantities of talc or TiO.sub.2. 
Advantageously, the aqueous solution containing the water glass can be 
impregnated at ambient temperature and at atmospheric pressure. 
Preferably, the solution also contains either a volatile or non-volatile 
flash suppressant which can be mixed with the water glass. Preferred 
volatile flash suppressants include NH.sub.4 HCO.sub.3, (NH.sub.4).sub.2 
CO.sub.3, and KHCO.sub.3. The volatile flash suppressant can be used with 
the water glass in amounts of from about 3%-26%, more preferably from 
about 3%-6% by weight. When preparing the aqueous solution, the volatile 
flash suppressant can be added to the solution either before or after the 
water glass, although it is preferred to add the water glass to the 
solution before the flash suppressant is introduced. 
The SiO.sub.2 acts as an erosion reducer when the charge is fired, and if 
potassium water glass is used, a source of potassium flash suppressant is 
supplied to the propellant gases. 
The water glass may be added in several different ways. The first addition 
technique is to add loose dry water glass powder. A second technique is to 
include 50/50 mixtures of dry water glass/ammonium bicarbonate and a water 
glass gel containing 60% water glass and 40% ammonium bicarbonate with a 
total amount of ammonium bicarbonate of 8%.
