Abstract
Abstract A firing safety device for handguns is disclosed. The device prevents the accidental discharge of the gun by children and is easily removeable by adults thereby resulting in the gun being ready for use almost immediately. The device includes a rod which is inserted into the gun barrel and into the cartridge chamber thereby preventing the cylinder from revolving. The rod is held in position by a cable which loops around the back of the gun. The device is removeable by inserting manual pressure to a cap at the front of the rod, which depresses a spring and releases the tension on the cable.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
91 words
A device for preventing the discharge of a firearm; said firearm having a barrel and a cartridge chamber; and including firing means for discharging a cartridge disposed in said cartridge chamber, comprising: a rod including an inner and an outer end disposed in and extending through said barrel; spring means coupled to said rod for applying force to the outer end of said rod; and cable means for coupling said spring means to said firing means thereby maintaining said rod in said barrel; whereby the discharge of said firearm is prevented.
Claim 2
Independent Claim
91 words
A device for preventing the discharge of a firearm; said firearm having a barrel and a cartridge chamber; and including firing means for discharging a cartridge disposed in said cartridge chamber, comprising: a rod including an inner and an outer end disposed in and extending through said barrel; spring means coupled to said rod for applying force to the outer end of said rod; and cable means for coupling said spring means to said firing means thereby maintaining said rod in said barrel; whereby the discharge of said firearm is prevented.
Claim 3
Dependent Claim
22 words
