ABSTRACT:
BACKGROUND
1. Field of Invention
This invention relates to guns, specifically to an improved cleaning and safety device for firearms.
2. Description of Prior Art
Previously guns were cleaned with implements that had to be left at home or carried separately from the firearm. Gun stores and gun catalogues offer cleaning kits for removing the residue left behind from burned gunpowder. One kit consists of a ramrod with a loop at the end. Another device consists of a ramrod surrounded with wool or “wooly rod”. After repeated uses the “wooly rod” is too filthy to hold additional soot and is ineffective. An effective cleaning of the cleaning kit is not practical and the wooly rod becomes useless.
A striker cartridge or “snap cap” (which does not clean a shotgun) is a device that allows the hammer inside the shotgun to release without damaging the hammer or firing pin. Gun cleaning ramrods, oil, cleaning solvent and striker cartridges are sold separately.
My firearm cleaning device incorporates the best aspects of a ramrod with a loop at the end, oil and/or solvent containers, striker cartridges and is shaped to be carried in the barrel of a gun. Originally the ramrod (with a loop at the end) for placing a patch usually made out of absorbent cloth was the preferred way to clean the barrels of shotguns. However the patch placed in the barrel is too small to remove the considerable amount of gunpowder residue that tends to accumulate and a new patch would have to be applied several times to complete the job.
In my firearm cleaning device the loop tip of a ramrod and a larger disposable cleaning element, such as a paper towel, can be used to remove more soot faster and with less effort. The striker cartridge along with a reservoir for holding oil and/or cleaning solvent serves as a handle for the ramrod and all can be stored inside the barrel of a gun.
In the instance of a double barreled shotgun both units of this firearm cleaning device can be carried in the firearm. This allows the owner of a gun to have a storage compartment for both oil and cleaning solvent, which creates a convenient way to clean a firearm after using it.
My firearm cleaning device differs from Patterson, U.S. Pat. No. 470,254 (1892), in that my device does not have a rod with a shouldered knob or a spiral thread formed around the ramrod. My firearm cleaning device has a locking extendable ramrod, which accommodates a ramrod tip designed to increase the surface area of a disposable cleaning element.
My firearm cleaning device differs from True, U.S. Pat. No. 852,748 (1907), Gardner, U.S. Pat. No. 2,616,109 (1952), Goodwin, U.S. Pat. No. 2,897,525 (1953), Ingalls, U.S. Pat. No. 3,137,957 (1964), Malesky et al., U.S. Pat. No. 4,399,627 (1983), Williams et al. U.S. Pat. No. 4,716,673 (1988), Black et al., U.S. Pat. No. 4,776,125 and Yeadon, U.S. Pat. No. 5,074,074 (1991) in that my firearm cleaning device does not have an elongated flexible shaft or cable. My firearm cleaning device is stored inside the barrel of a gun and has a built in striker-cartridge in the end of the ramrod.
My firearm cleaning device differs from Southgate, U.S. Pat. No. 1,067,383 (1913) and Geltner, U.S. Pat. No. 2,744,275 (1956) in that the locking mechanism of my device's rod are different. Southgate's locking mechanism which is employed for each of its several sections will fail the moment the user applies a clockwise with pushing motion. To clean the barrel of a firearm without twisting the ramrod is unrealistic. Geltner's rod locking mechanism works on only one side of his ramrod's sections the moment pressure is applied to the other side of any of the ramrod's sections they won't work.
My firearm cleaning device differs from McGavisk, U.S. Pat. No. 1,229,991 (1917) in that my device does not have a threaded rod connected to a disk, or a means for closing the muzzle end of a gun's barrel to prevent oil from leaking out of the barrel. My device does not include or need an oil retainer for the barrel of a gun.
My firearm cleaning device differs from Olberding, U.S. Pat. No. 1,526,177 (1925) in that my device does not have coaction catches at the meeting ends to hold a rod in either the extended or contracted position or a screw stem for securing a patch.
My firearm cleaning device differs from Belding, U.S. Pat. No. 1,532,223 (1925) and Eckert, U.S. Pat. No. 3,286,293 (1966) in that my device does not have a stop collar or stop means for its ramrod. Belding or Eckert's invention would be superfluous in conjunction with my device.
My firearm cleaning device differs from Dake, U.S. Pat. No. 1,665,257 (1928) in that Dake shows the cleaning patch detachable, whereas the patch in my device is held to rod.
My gun cleaning device differs from Jack, U.S. Pat. No. 2,405,308 (1946) in that my device does not have a metallic shell element provided with a plunger in a bore or a design having the same weight as a live cartridge. My device is designed not to be mistaken for a live round which eliminates the possibility of deadly consequences for its owner.
My firearm cleaning device differs from Hoard, U.S. Pat. No. 2,594,778 (1952) and Doyle, U.S. Pat. No. 2,985,979 (1961) because both show moisture reduction and rust prevention methods, which incorporates plugs, a far different invention than mine.
My firearm cleaning device differs from Huckabee, U.S. Pat. No. 2,763,081 (1956), Healey et al., U.S. Pat. No. 4,969,284 (1990) and Brown, U.S. Pat. No. 5,038,508 (1991) in that my firearm cleaning device is not a ridged locked-rod type of disabling or sealing device. The striker-cartridge aspect of Healey's firearm cleaning device is a resilient material, whereas mine is spring operated.
My firearm cleaning device differs from Lewis et al., U.S. Pat. No. 3,208,302 (1965) because by device does not contain a releasable locking mechanism in its handle. My device is designed to obviate the need of a swivel handle in its ramrod.
My firearm cleaning device differs from McConnell, U.S. Pat. No. 3,564,746 (1971) in that my device does not have a plunger or a cap that can be unscrewed if the plunger needs to be replaced because of damage by repeated use. My device contains a pin that is non deforming and designed not to need replacement. McConnell's invention does not have a rim around the breech end, is positioned by hand and is hand-held during use as a snap cap substitute.
My firearm cleaning device differs from DiProspero, U.S. Pat. No. 4,010,565 (1977) in that my firearm cleaning device does not have a tip end which is received in a cylindrical member, having a reduced size cylindrical end, for fitting into a cylindrical cup. My firearm cleaning device has a collapsible rod and stores oil and or solvent instead of patches in the handle. My firearm cleaning device is designed to be stored inside the barrel of a gun and has a built in striker cartridge in the handle of the ramrod.
My firearm cleaning device differs from Cech, U.S. Pat. No. 4,100,693 (1978) in that Cech's claim 1 has an impact element arranged eccentrically to the cartridge jacket's longitudinal axis, and the impact element is rotatably mounted in this opening. In addition Cech further claims a cartridge jacket wall with openings and a sleeve-like insert. The sleeve like insert contains a known chemical substance diffusing a corrosion-preventing gas, is replaceably mounted within the generally tubular side wall, and supplied to at least one additional opening serving to feed the gas to the breech area of a shotgun. Cech has no attachment for oil or cleaning solvent containers, no two piece extendable ramrod and no rod tip to accommodate a disposable cleaning element.
My firearm cleaning device differs from Jurich, III, U.S. Pat. No. 4,195,381 (1980), Zurek et al., U.S. Pat. No. 4,726,137 (1988), Stephan, U.S. Pat. No. 5,038,509 (1991), and Selleck, U.S. Pat. No. 5,075,998 (1991), in that my firearm cleaning device does not have an attached brush(s), a plurality of short, parallel shafts which are mechanically coupled to a triangularly s
