Abstract
Abstract A device is disclosed for preventing unauthorized loading and discharge of firearms. Unlike other devices that prevent trigger action, or disable firearms by interfering with the function of their mechanisms, the device disclosed prevents loading of the firearm by blocking the barrel bore with a cable or other flexible means which is securely locked externally to the barrel, thereby blocking a cartridge from the firing position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
A firearm loading lockout device that prevents a firearm from being loaded and discharged either accidentally or intentionally comprising in combination: (a) a flexible member that is passed through the bore of the barrel of said firearm, thereby blocking a cartridge from being loaded into firing position, or, thereby preventing the mechanism of the firearm from being closed into the firing position, or both; (b) at least one termination fitting that is affixed to at least one end of said flexible member, and which is smaller in cross section than the bore of said firearm; (c) a plate that has a hole through which the shackle of a lock and said termination fitting may pass independently, and a slot that adjoins said hole through which said flexible member may pass freely, but through which said termination fitting cannot pass; (d) a lock that has a shackle that passes freely through said hole, but said shackle is sufficiently large in cross section that said termination fitting cannot pass through said hole when said shackle occupies said hole.
Claim 2
Dependent Claim
