| Inventors: | Knopp, Joseph P. (Lincoln, NB) |
| Claim: | Having thus described the invention, I claim |
| Claim: | 1. A safety device for a firearm having a hollow barrel with a muzzle end and a firing chamber located at the opposite end of the barrel, said device comprising in combination |
| Claim: | an elongate rod adapted to be inserted from said muzzle end into said barrel and firing chamber to grippingly engage the interior wall of said barrel, said rod being shorter in length that the combined length of said barrel and firing chamber; |
| Claim: | a tool for inserting and removing said rod from the barrel and firing chamber, said tool including a shank portion smaller in size than said barrel and of sufficient length to push said rod into said firing chamber when said shank portion is inserted into said barrel from the muzzle end; and |
| Claim: | means for coupling said shank portion of the tool with said one end of the rod within said barrel, whereby said tool may be pulled outwardly of the muzzle end of said barrel to remove said rod therefrom. |
| Claim: | 2. The invention of claim 1, wherein said rod is of smaller diameter than said barrel and includes spaced apart ribs extending generally longitudinally along the exterior surface of said rod, said ribs grippingly engaging the interior wall of said barrel to retain said rod therein. |
| Claim: | 3. The invention of claim 2, wherein said ribs are resiliently deformable to permit said rod to be received in barrels having different bore sizes. |
| Claim: | 4. The invention of claim 2, wherein each rib is tapered outwardly from said rod. |
| Claim: | 5. The invention of claim 1, wherein said coupling means comprises a threaded connection of said tool with said one rod end. |
| Claim: | 6. The invention of claim 1, including an enlarged handle on said tool connected with said shank portion at one end thereof. |
| Claim: | 7. The invention of claim 1, wherein said one end of the rod is tapped and threaded and said shank portion of said tool has an end which is matingly threaded to provide said coupling means. |
| Claim: | 8. The invention of claim 7, including an enlarged handle of said tool connected with said shank portion at the end thereof opposite the end which is threaded. |
| Claim: | 9. The invention of claim 7, wherein said rod is of smaller diameter than said barrel and includes a plurality of spaced apart ribs extending generally longitudinally along the exterior surface of said rod, said ribs grippingly engaging the internal walls of said barrel to retain said rod therein. |
| Claim: | 10. The invention of claim 9, wherein each rib is tapered outwardly from said rod. |
