Abstract
A chamber and bore lock for a firearm includes a rod adapted for receipt within the barrel bore of the firearm. One end of the rod has a fixed plug with an abutting O-ring. A pair of sleeves are received upon the rod with an O-ring therebetween. A threaded cap engages an end of the rod at the muzzle of the firearm, such that threaded movement of the cap draws the plug toward the cap, urging the sleeves into compressing and radially deforming engagement with the O-rings which engage inner circumferential surfaces of the barrel bore and firing chamber of the firearm.
Claims18
A safety mechanism for receipt within the bore of a barrel of a firearm, comprising:
- a rod having first and second ends;
- a sleeve received upon said rod;
- means received upon said rod for radially expanding into securing contacting engagement with the bore in response to axial movement of said sleeve upon said rod, said means comprising a first O-ring interposed between a first end of said sleeve and said plug, said first O-ring radially expanding therebetween in response to axial movement of said sleeve upon said rod;
- a plug fixed at said first end of said rod and a head threadedly received on said second end of said rod, said head engaging said sleeve;
- and
- wherein said plug is received within a firing chamber of the firearm, said first O-ring making securing engagement with the firing chamber.
A safety device for securing a firearm, comprising:
- a rod, threaded at a first end thereof and having a plug fixed to a second end thereof;
- a sleeve slidingly received upon said rod;
- a first expandable ring received upon said rod;
- and
- a head threadedly received upon said second end of said rod, threaded movement of said head and rod urging said sleeve into compressing engagement with said expandable ring, deforming said ring into radial contacting engagement with a bore of the firearm, said head having a chamfered recess centrally therein and a shoulder extending radially from the body portion, a thin web of weakened material extending between said chamfered recess and shoulder.
A safety device for securing a firearm, comprising:
- a rod, threaded at a first end thereof and having a plug fixed to a second end thereof, said plug being received in a firing chamber of the firearm;
- a sleeve slidingly received upon said rod;
- a first expandable ring received upon said rod and engaging a shoulder of the firing chamber, and
- a head threadedly received upon said second end of said rod, threaded movement of said head and rod urging said sleeve into compressing engagement with said expandable ring between said sleeve and said plug, deforming said ring into radial contacting engagement with a bore of the firearm.
A safety device for securing a firearm, comprising:
- a rod, threaded at a first end thereof and having a plug fixed to a second end thereof, said plug being received within a bore of a cylinder of the firearm;
- a sleeve slidingly received upon said rod;
- a first expandable ring received upon said rod;
- and
- a head threadedly received upon said second end of said rod, threaded movement of said head and rod urging said sleeve into compressing engagement with said expandable ring, deforming said ring into radial contacting engagement with a bore of the firearm.
A safety device for securing a firearm, comprising:
- a rod, threaded at a first end thereof and having a plug fixed to a second end thereof;
- a sleeve slidingly received upon said rod;
- a first expandable ring received upon said rod;
- a head threadedly received upon said second end of said rod, threaded movement of said head and rod urging said sleeve into compressing engagement with said expandable ring, deforming said ring into radial contacting engagement with a bore of the firearm;
- and
- a locking insert within said threaded first end of said rod for locking engagement with said head.
