Firearm barrel cleaning shell

Abstract

A firearm barrel cleaning shell including a casing carrying a primer at one of its ends and having an opening at the other of its ends. A blast conduit is positioned within the casing so as to receive the discharge from the primer and to direct the discharge toward the opening in the casing. A projectile is positioned within the casing and includes an ejectable plug that, before the discharge of the primer, closes the opening in the casing. A flexible tether connects the plug to an oil-saturated pad is positioned adjacent the primer and a solvent-saturated pad positioned between the plug and the oil-saturated pad.

1 . A firearm barrel cleaning shell, comprising: 
 a casing having opposed ends and carrying a primer at one of said ends and having an opening at the other of said ends;    a blast conduit being positioned within said casing so as to receive the discharge from said primer and to direct the discharge toward said opening;    a projectile being positioned within said casing, said projectile including: 
 an ejectable plug closing said opening;  
 an oil-saturated pad positioned adjacent said primer;  
 a solvent-saturated pad positioned between said plug and said oil-saturated pad; and,  
 a flexible tether connecting said plug, said oil-saturated pad and said solvent-saturated pad.  
   
   
   
       2 . The firearm barrel cleaning shell according to  claim 1  wherein said oiling pad includes: 
 a first wiper ring being formed of a substantially impermeable material and being dimensioned to snugly, yet slidably, engage said casing and said blast conduit; and,    a first applicator ring being formed of an oil-saturated fibrous material and being bonded to said first wiper ring, said first applicator ring being dimensioned to snugly, yet slidably, engage said casing and said blast conduit.    
   
   
       3 . The firearm barrel cleaning shell according to  claim 2  wherein said cleaning pad includes 
 a second wiper ring being formed of a substantially impermeable material and being dimensioned to snugly, yet slidably, engage said casing and said blast conduit; and,    a second applicator ring being formed of a solvent-saturated fibrous material and being bonded to said second wiper ring, said second applicator ring being dimensioned to snugly, yet slidably, engage said casing and said blast conduit.    
   
   
       4 . The firearm barrel cleaning shell according to  claim 1  wherein said tether comprises a length of string.  
   
   
       5 . The firearm barrel cleaning shell according to  claim 1  wherein said tether has a tether segment connecting said plug to said cleaning pad having a length that is about eight times that of said casing.  
   
   
       6 . A firearm barrel cleaning shell, comprising: 
 a casing adapted for positioning within the firing chamber of a firearm, said casing having opposed ends and carrying a primer adapted to explosively discharge gases upon being struck by the firing pin of a firearm at one of said ends and having an opening at the other of said ends;    a blast conduit being positioned within said casing so as to define an annulus between said blast conduit and said casing, said blast conduit having an inner end positioned about said primer so as to receive the discharge from said primer and also having an outer end positioned adjacent said opening;    a projectile being positioned within said casing, said projectile including, said projectile including: 
 an ejectable plug closing said opening;  
 an oiling pad positioned within said annulus and adjacent said primer;  
 a cleaning pad positioned within said annulus and between said plug and said oiling pad; and,  
 a flexible tether positioned within said annulus and connecting said plug, said oiling pad and said cleaning pad.  
   
   
   
       7 . The firearm barrel cleaning shell according to  claim 6  wherein said oiling pad includes: 
 a first wiper ring being formed of a substantially impermeable material and being dimensioned to snugly, yet slidably, engage said casing and said blast conduit; and,    a first applicator ring being formed of an oil-saturated fibrous material and being bonded to said first wiper ring, said first applicator ring being dimensioned to snugly, yet slidably, engage said casing and said blast conduit.    
   
   
       8 . The firearm barrel cleaning shell according to  claim 7  wherein said cleaning pad includes a second wiper ring being formed of a substantially impermeable material and being dimensioned to snugly, yet slidably, engage said casing and said blast conduit; and, 
 a second applicator ring being formed of a solvent-saturated fibrous material and being bonded to said second wiper ring, said second applicator ring being dimensioned to snugly, yet slidably, engage said casing and said blast conduit.    
   
   
       9 . The firearm barrel cleaning shell according to  claim 6  wherein said tether comprises a length of string.  
   
   
       10 . The firearm barrel cleaning shell according to  claim 6  wherein said tether has a tether segment connecting said plug to said cleaning pad having a length that is about eight times that of said casing.  
   
   
       11 . A firearm barrel cleaning shell, comprising: 
 a casing adapted for positioning within the firing chamber of a firearm, said casing having opposed ends and carrying at one of said ends a primer adapted to explosively discharge gases upon being struck by the firing pin of a firearm and having an opening at the other of said ends;    a blast conduit being centrally positioned within said casing so as to define an annulus between said blast conduit and said casing, said blast conduit having an inner end positioned about said primer so as to receive the discharge from said primer and also having an outer end in fluid communication with said inner end for directing the discharge from said primer toward said opening;    a projectile being positioned within said casing, said projectile including: 
 an ejectable plug closing said opening;  
 an oiling pad positioned within said annulus and adjacent said primer;  
 a plurality of cleaning pads positioned within said annulus and between said plug and said oiling pad; and,  
 a pair of flexible tethers positioned within said annulus and connecting said plug, said oiling pad and said cleaning pads together in a train.
