Center fire pistol and rifle cartridge case polishing apparatus

Abstract

What is new in the art of the invention is that it will accommodate all sizes of, Boxer style, spent center fire brass pistol and rifle casings faster, safer, more economically, more environmentally sound, with less parts (see Mancini/Galloway), and far better than the use of a media tumbler currently used for this purpose.

1 . A device that will allow for the attaching of a spent, de-primed center fire pistol and rifle cartridge cases of all sizes up to 0.50 cal. to a drill and turned longitudinally for cleaning and polishing prior to reloading same comprising:
 A cone shaped restrainer bored axially that is at least partially internally threaded ;   A threaded rod with external threads along a portion of its surface that mate with the threads of the retainer;   A body piece that is drilled axially through the center with a set screw perpendicular to the axis for restraining the rod ;   A body piece that is machined on one end to fit the jaws of a drill chuck;   A body piece that is machined on the opposite end to fit into the primer pocket of large pistol and rifle primers;   
     
     
         2 . A device in accordance with  claim 1 , that automatically aligns the spent casing axially and checks that the flash hole is centered in primer pocket; 
     
     
         3 . A device in accordance with  claim 2 , that will function on all center fire casings without the need for additional parts or shell holders; 
     
     
         4 . A device in accordance with  claim 3 , that is intended to be used in the art of reloading spent rifle and or pistol center fire casings with boxer primer style flash holes and any other similar application. 
     
     
         5 . A device that is intended to be used in the art of case preparation, specifically, cleaning, polishing to minimize scratches, remove excessive tarnishing, discoloration, allowing easier inspection for case defects, and greatly improve general appearance through the use of a mild abrasive such as steel wool, scotch brite, and/or brass cleaners while rotating in a drill the steps are; thread rod onto cone so rod is flush with flat end of cone, insert rod from case neck end through flash hole and out primer pocket, insert rod into axial bore of body at end nearest set screw, allow rod to slide through bore until casing is in full contact with both body and cone, tighten set screw, snug cone to secure casing, place three sided end of body in drill and rotate drill while using steel wool to clean and polish casing. Remove cone by counter rotating drill, remove casing. The apparatus is now set to clean casings of the same caliber by inserting casing onto threaded rod through the flash hole and screwing the cone onto the threads contacting the neck opening of the casing with the conical end of the cone. Repeat for subsequent casings.
