With Bore Cleaning Means Patents (Class 102/442)
  • Patent number: 10302385
    Abstract: A bore cleaning device includes a propellant, a gas seal situated proximate to the propellant, a bore rearward disk, a fibrous cup, and a bore forward disk. The bore forward disk is configured to press against a bottom surface of the fibrous cup, wherein the bore forward disk is narrower than a diameter of a bore of a firearm such that a gap exists around a circumference of the bore forward disk between the bore forward disk and the bore of the firearm. The gap is configured to enable the cup to deform into the gap. The device further includes a cylindrically shaped stack of cleaning materials between the bore rearward disk and the bore forward disk, wherein the stack of cleaning materials is configured to longitudinally transmit at least a portion of the force from the bore rearward disk to the bore forward disk.

  • Patent number: 10018455
    Abstract: An apparatus is disclosed including a bore cleaning device configured to clean a bore of a firearm. The device includes a propellant providing a force to push the projectile down the bore of the firearm, a fibrous cup, a dense material within the fibrous cup, and a frame including a bore forward disk configured to press against a bottom surface of the fibrous cup. The dense material includes one of a dense granulated material and a dense, viscous paste. The dense material is configured to deform and press radially outwardly against the cup as the propellant provides propelling force to the dense material.

  • Patent number: 9664487
    Abstract: A bore cleaning projectile cleans a bore of a firearm as the projectile is propelled down the bore. The projectile includes a frame including a lower charge cap, a tapered cone-shaped center shaft portion, and an end cap. The projectile further includes a propellant providing a force to push the device down the bore of the firearm and at least one cleaning agent situated around the tapered cone-shaped center shaft portion. The center shaft portion includes a narrower diameter at a longitudinally forward portion of the center shaft portion and a wider diameter at a longitudinally rearward portion of the center shaft portion. The cleaning agent is forced to move along the center shaft portion toward the longitudinally rearward portion of the center shaft portion as the frame is propelled down the bore. This movement along the center shaft portion causes intimate contact between the cleaning agent and the bore.

  • Patent number: 9212879
    Abstract: A bore cleaning device is disclosed including a propellant providing a force to push the projectile down the bore of the firearm, a frame including a plurality of collapsible legs, and a cylindrically-shaped cleaning agent installed around the legs. The frame further includes a lower charge cap configured to receive the force of the propellant and a rigid front end cap. The provided force creates a crushing force upon the frame. The crushing force causes the legs to collapse and provide an outward force upon the cleaning agent, wherein the outward force causes intimate contact between the cleaning agent and the bore as the device travels along the bore.

  • Patent number: 7743706
    Abstract: A bullet for cleaning/scouring the interior surface of a gun barrel including a jacket section on a rear end and joined to a projectile section on the other end forming a chamber containing a cleaning liquid. An array of brushes is positioned on the outside surface of the forward wall of the projectile section. An explosive cake is positioned against the rear end of the jacket section. A piston disk is positioned against the cake. When the cake is detonated, the disk first expels fluid from the chamber and against the interior wall of the barrel. Then the disk forces the forward wall to spread out so that the brushes on the forward wall come into contact with the interior surface of the gun barrel.

  • Patent number: 4328632
    Abstract: A cleaning device for firearms having a firing pin and a barrel with a shell chamber, in which a casing contains several barrel cleaning layers consisting of an abrasive, solvent, wiper and lubricant layers. A propellant is disposed in the casing in close proximity to the firing pin which activates the propellant to propel the cleaning layers through the barrel. The propellant may be a cartridge containing CO.sub.2, having a neck and cap in close proximity to the firing pin which strikes and ruptures the cap to release the CO.sub.2 and drive the cleaning layers through the barrel. A soft fabric may be disposed around the cartridge, and may be impregnated with lubricant for treating the barrel after the cleaning layers have passed therethrough.
