Description
W. W. WEESE BORE CLEANING BULLET Filed July 25; 1944 mmvroza. Wilfred W. Weese BY WW Patented May 25, 1948 UNITED STATES PATENT OFFICE BORE CLEANING BULLET Wilfred W. Weese, West Englewood, N. J. Application July 25, 1944, Serial No. 546,521
3 Claims.
The invention relates to a bullet adapted to be fired through the bore of the barrel of a firearm and which effects the cleaning of the bore and the removal of any foreign matter which may be present therein.
The main object of the invention is to provide a bullet, made of a powdered metal and an abrasive substance which may be loaded in a standard cartridge case, with a standard primer and powder charge, and which, when fired through the bore of the barrel of a firearm, will effectively clean said bore.
A further object of the invention is to provide a bullet which will remove any metal fouling present in the bore of the barrel of a firearm when it is fired therethrough.
A further object is to provide a bullet which will remove the powder and primer residue from the bore of the barrel of a firearm when it is fired therethrough.
A further object is to provide a bullet which will polish and remove irregularities from the bore of the barrel of a firearm when it is fired therethrough.
Other and more detailed objects will appear in the specifications and will be specifically pointed out in the appended claims.
In the normal use of sporting firearms, such as rifies, pistols and revolvers, the bore of the barrels of said firearms, after a period of time, becomes fouled by powder residue, primer residue, and other products of combustion, and also by an accumulation of bullet metal which becomes deposited in the bore by the bullets which pass therethrough under great heat and pressure. The presence of such fouling tends to cause oxidation with resultant rust spots and rust pits in the bore. ihese conditions when they exist in the firearm tend to destroy its shooting accuracy and if the fouling is of an aggravated character it will often render the firearm useless.
It has been the previous practice, after a firearm has been used, to clean the same by manually inserting a cleaning rod and cleaning materials into the bore of the barrel and then to manipulate said cleaning rod and cleaning material to dislodge the undesirable foreign matter which has become deposited in the bore. This method of cleaning the bore of the firearm barrel is not only a tedious procedure but oftentimes it does not thoroughly accomplish the cleaning.
The bullet made in accordance with the present invention not only simplifies the cleaning of the bore of firearm barrels but also will more effec tively and more completely remove all the foreign tridge case for the bullet is shown at 2. The
bullet is made of a finely divided metallic powder, preferably zinc, which is mixed with a fine abrasive powder, which may include a garnet powder or a powdered cuttle fishbone, or a mixture of both. The abrasive powder comprises about 20% to 30% of the bullet mixture and the metallic powder forms about or thereof. In forming the bullet this mixture of metallic powder and abrasive powder is compressed in a hardened steel or carbide mold of a size and type suitable to make the bullet of a particular caliber for use in a particular firearm. The bullet after being thus molded to shape may then be subjected to heat in order to produce a greater strength and toughness of the metallic bond for the contained abrasive material. When the combining process of the metallic powder and the abrasive material and the molding of the bullet is completed it is caused to be seated, in a usual manner, in a standard cartridge case of the required caliber, indicated at 2 in the drawing, and which cartridge case contains either a standard or a modified powder charge.
The bullet, made in the manner above described, is fired solely in a firearm for the purpose of eifecting the cleaning of the bore of the barrel of said firearm and is not intended to be used as an ordinary bullet to be directed at some designated target. In use it will be fired into the air or into the ground, or towards some nearby area where it will do no harm. As the bullet is projected through the bore of the barrel of the firearm the material of which it is made will cause an abrasive action to be transmitted to the metal of the bore of the barrel and said abrasive action will effect a cleaning and polishing of said bore and will also remove any foreign substance which may have become deposited therein. It has been found that not more than twenty of the bullets are required to be fired through the bore to correct the most severe cases of rusted or fouled bores of rifles, pistols or revolvers, and that bores of the barrels of the average sporting arms which have been neglected between hunting seasons can gether to form an intimately bonded and hard ened molded body having an exterior surface provided with an abrasive grain.
3. A bullet for firearms comprisedof a mixture of zinc powder, garnet powder and powdered cuttlefish bone compressed together to'form an 4 intimately bonded and hardened molded body having an exterior surface provided with an abrasive grain.
