ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to a cleaning and lubricating solution for guns, gun bores, cartridges, and gun parts, and more especially for black powder guns, gun bores, cartridges, and gun parts.
The present invention comprises a cleaning and lubricating solution containing a fatty acid compound such as an oleate, an oxidizing agent preferably hydrogen peroxide solution, and an alcohol. A bittering agent is generally included, but is not essential to the performance of the cleaning and lubricating solution.
Unlike modern firearms, black powder firearms are not blued or chromed in that the black powder, (“also known as blasting powder”), contains a brown or black explosive mixture of potassium nitrate, charcoal, and sulfur which is corrosive to such a finish. In some cases, sodium nitrate is substituted for potassium nitrate. Typical proportions are 75%, 15%, and 10%, respectively. Originally gun powder was made in powder form, whereas today it is formed into grains of various sizes. It is sensitive to heat and deflagrates rapidly. It does not detonate, but is a dangerous fire and explosion hazard. Besides gunpowder, black powder is still used for time fuses for blasting, in large caliber artillery shells, in igniter and primer assemblies for propellants, pyrotechnics, and mining.
2. Description of the Prior Art
Due to the corrosive chemical nature of black powder on steel, black powder guns must be cleaned immediately upon use, and may rust in less than two hours within use. Black powder guns, whether inline, caplock, flintlock, or large caliber military guns need to be cleaned after every shot or two to maintain good accuracy. Because of the corrosiveness of black powder cleaning is very important in protecting an investment in these weapons.
Conventional methods of cleaning black powder guns consisted of filling the barrel with hot soapy water and swapping a patch back and forth through the barrel bore until the patch was white indicating the barrel bore was clean. Typically the gun barrel and bore was lubricated with a light oil to prevent rust.
Furthermore, black powder weapons accumulate a seasoning over time like an “iron skillet”. Conventional petroleum-based cleaners now on the market tend to strip all of that seasoning out of the gun barrel bore leaving the weapon vulnerable to rust in that it strips the protective patina from the metal.
SUMMARY OF THE INVENTION
The present invention is used to clean dirt and debris from the bores and other parts of black powder firearms and accessories. The solution cleans the bore and coats it with a lubricant comprising an oil such as a GRAS vegetable oil. The solution is safe for use with modern firearms, whether nickel plated, blued, or stainless steel, as well as carbon steel antique weapons, and is considered to be an “environmentally-friendly” product.
The cleaning and lubricating solution of the present invention may be used straight from the container and poured into a gun barrel bore, or even onto the metal surface of the gun. Moreover, the cleaning and lubricating solution may be incorporated into gun oil, pre-lubricated muzzle loader patches, bore conditioners, and or bullet lubricants.
It is an object of the present invention to provide an inexpensive cleaning and lubricating solution which may be used for black powder guns in a single step so that the treated gun bore is cleaned and a lubricant film is formed upon draining from the barrel.
It is another object of the present invention to provide a cleaning and lubricating solution for black powder guns which is environmentally friendly and generally recognized as safe for the user.
It is another object of the present invention to be able to use the cleaning and lubricating solution in a short time span.
It is another object of the present invention to provide a solution which may be applied by brush, spray, dipping, and/or swabbing.
It is another object of the present invention to provide a cleaning solution which will not harm the lubrication seasoning in the bore.
It is another object of the present invention to provide a cleaning and lubricating solution which is compatible with existing gun oils and lubricants.
It is another object of the present invention to provide a cleaning and lubricating solution which exhibits a foaming action thereby providing a self cleaning lubricant which penetrates into the cracks and crevices of the metal to clean and lubricate.
It is another object of the present invention to provide a cleaning and lubricating solution which acts to passivate the metal.
It is yet another object of the present invention to provide a cleaning and lubricating solution for black powder applications wherein the amount of fouling in the bore make no difference.
Finally, it is an object of the present invention to provide a solution which may be used to wipe off the metal around the lock to prevent corrosion.
The foregoing objects are accomplished by the cleaning and lubricating solution of the present invention.
Preferred compositions of the black powder cleaning and lubricating solution typically contain a hydrogen peroxide solution in an amount ranging from about 15 percent to about 50 percent by weight of the total weight percent of the composition based on a 4% solution; an alcohol in an amount ranging from about 15 percent to about 50 percent by weight of the total weight percent of the composition; and a fatty acid soap in an amount ranging from about 15 percent to 60 percent by weight of the total weight percent of the composition. One preferred embodiment comprises about one-third of a fatty acid, about one-third of an alcohol, and about one-third of a 4% hydrogen peroxide solution. One or more bittering agents may be utilized with the above aforementioned ingredients.
