Abstract
A mechanism for disabling a firearm is provided. The disablement mechanism includes a body positionable to contact a portion of the hammer spring assembly in order to prevent the hammer from being moved to its cocked position. The disablement mechanism is also positionable to prevent the hammer from firing a cartridge when the hammer is released from its cocked position.
Claims28
An apparatus for firing a cartridge, comprising:
- a firearm including a hammer movable between a cocked position and an uncocked position;
- a trigger assembly connected with said hammer for releasing said hammer from the cocked position upon actuation of said trigger assembly;
- a hammer spring assembly connected with said hammer, said hammer spring assembly including a spring tensioned upon cocking of said hammer to thereafter cause said hammer to fire the cartridge upon actuation of said trigger assembly;
- and
- a disablement mechanism positionable with respect to said hammer spring assembly to prevent said hammer from being cocked if in the uncocked position and from being trigger-actuated if in the cocked position.
An apparatus for disabling a firearm, said firearm including a hammer movable between a cocked position and an uncocked position, a trigger assembly connected with the hammer for releasing the hammer from the cocked position upon actuation of the trigger assembly, and a spring positioned within a well of a spring housing, the spring being tensioned upon cocking of the hammer to provide energy to the hammer upon actuation of the trigger assembly, the apparatus comprising:
- a hammer strut connected at one end with the hammer and having a length extending to an opposite end;
- a spring cap having a head portion positioned on the spring, the opposite end of said hammer strut abutting said spring cap;
- and
- a disablement mechanism received within a bore in the spring housing, said disablement mechanism movable from a first position where the firearm is enabled to a second position wherein said disablement mechanism contacts said head portion of said spring cap where the firearm is disabled.
A method for retrofitting a firearm, comprising:
- providing a firearm having a hammer movable between a cocked position and an uncocked position, and a hammer spring assembly connected with the hammer, the hammer spring assembly including a spring and a first spring cap positioned on the spring within a well of a first spring housing;
- disassembling the hammer spring assembly from the firearm;
- providing a second spring housing having a well and a bore formed through the housing communicating with the well;
- providing a disablement mechanism positionable within the bore;
- providing a second spring cap having a head portion configured for contact with the disablement mechanism to disable the firearm when the hammer is in either the cocked position or the uncocked position;
- and
- reassembling the firearm with the second spring cap positioned within the second spring housing.
An apparatus for disabling a firearm, the firearm having a hammer movable between a cocked position and an uncocked position, and a spring positioned within a well of a spring housing, the spring being tensioned when the hammer is cocked, the apparatus comprising:
- a spring cap having a head portion positioned on the spring, the hammer being connected with said spring cap;
- and
- a body received within a bore formed in the spring housing, said body having a first end and an opposite second end and a length extending therebetween, said body being movable from a first position where the firearm is enabled to a second position wherein contact between said body and said head portion of said spring cap disables the firearm.
