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.

Claims

1. An apparatus comprising a bore cleaning device configured to clean a bore of a firearm, the device comprising:

a frame comprising;

a lower charge cap;

a tapered cone-shaped center shaft portion; and

an end cap;

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;

wherein the tapered cone-shaped center shaft portion includes a narrower diameter at a longitudinally forward portion of the tapered cone-shaped center shaft portion and a wider diameter at a longitudinally rearward portion of the tapered cone-shaped center shaft portion; and

wherein the cleaning agent is forced to move along the tapered cone-shaped center shaft portion toward the longitudinally rearward portion of the tapered cone-shaped center shaft portion as the frame is propelled down the bore, the movement causing intimate contact between the cleaning agent and the bore.

2. The apparatus of claim 1, wherein the end cap comprises a collapsing table portion;

and

further comprising at least one frangible capsule located within the collapsing table portion.

3. The apparatus of claim 1, wherein the end cap is fixed to an end of the tapered cone-shaped center shaft portion.

4. The apparatus of claim 1, wherein the end cap is configured to slide along the tapered cone-shaped center shaft portion.

5. The apparatus of claim 1, further comprising a plurality of cleaning agents situated around the tapered cone-shaped center shaft portion;

and

wherein the cleaning agents are forced to move along the tapered cone-shaped center shaft portion toward the longitudinally rearward portion of the tapered cone-shaped center shaft portion as the frame is propelled down the bore, the movement causing intimate contact between the cleaning agents and the bore.

6. The apparatus of claim 5, wherein the cleaning agents comprise a cylindrically-shaped fibrous cleaning agent, a cylindrically-shaped high density felt cleaning agent, and two disk-shaped rubberized wipers.

7. An apparatus comprising a bore cleaning device configured to clean a bore of a firearm, the device comprising:

a frame comprising;

a lower charge cap;

a tapered cone-shaped center shaft portion; and

an end cap affixed to an end of the tapered cone-shaped center shaft portion;

a propellant providing a force to push the device down the bore of the firearm; and

a plurality of cleaning agents situated around the tapered cone-shaped center shaft portion;

wherein the tapered cone-shaped center shaft portion includes a narrower diameter at a longitudinally forward portion of the tapered cone-shaped center shaft portion and a wider diameter at a longitudinally rearward portion of the tapered cone-shaped center shaft portion; and

wherein the cleaning agents are forced to move along the tapered cone-shaped center shaft portion toward the longitudinally rearward portion of the tapered cone-shaped center shaft portion as the frame is propelled down the bore, the movement causing intimate contact between the cleaning agents and the bore.

8. An apparatus comprising a bore cleaning device configured to clean a bore of a firearm, the device comprising:

a frame comprising;

a lower charge cap;

a tapered cone-shaped center shaft portion; and

an end cap configured to slide along the tapered cone-shaped center shaft portion;

a propellant providing a force to push the device down the bore of the firearm; and

a plurality of cleaning agents situated around the tapered cone-shaped center shaft portion;

wherein the tapered cone-shaped center shaft portion includes a narrower diameter at a longitudinally forward portion of the tapered cone-shaped center shaft portion and a wider diameter at a longitudinally rearward portion of the tapered cone-shaped center shaft portion; and

wherein the cleaning agents are forced to move along the tapered cone-shaped center shaft portion toward the longitudinally rearward portion of the tapered cone-shaped center shaft portion as the frame is propelled down the bore, the movement causing intimate contact between the cleaning agents and the bore.
