Abstract
A novel firearm safety feature includes arresting surfaces for preventing the fall of a hammer in the event of a spontaneous failure of other firearm parts. In a particular embodiment a safety lug has an arresting surface and the hammer has a complementary arresting surface. In the event of a spontaneous failure, the arresting surface and the complementary arresting surface create a positive engagement and prevent the hammer from falling. In another embodiment, a grip safety includes an arresting surface and the hammer includes a complementary arresting surface. In the event of a spontaneous failure, the arresting surface and the complementary arresting surface create a positive engagement and prevent the hammer from falling.
Claims19
A firearm safety feature, comprising:
- a firing pin;
- a hammer spring;
- a hammer biased by said hammer spring to rotate in a first direction to impact said firing pin, said hammer including an arresting surface;
- a sear operative to engage said hammer such that said hammer is prevented from rotating toward said firing pin;
- a trigger operative to disengage said sear from said hammer, allowing said hammer to rotate in said first direction toward said firing pin;
- a safety switchable between a safe position and a firing position, a portion of said safety positioned to prevent said sear from disengaging said hammer when said trigger is depressed;
- and wherein
- said safety includes a complementary arresting surface;
- and
- said arresting surface and said complementary arresting surface become positively engaged under influence of said hammer spring when said safety is in said safe position and said hammer rotates in said first direction, preventing said hammer from impacting said firing pin.
A firearm safety feature, comprising:
- a firing pin;
- a hammer spring;
- a hammer biased by said hammer spring to rotate in a first direction to impact said firing pin, said hammer including an arresting surface;
- a sear operative to engage said hammer to prevent rotation of said hammer in said first direction and said hammer impacting said firing pin;
- a trigger operative to engage said sear such that when said trigger is depressed said sear disengages from said hammer, allowing said hammer to rotate in said first direction and impact said firing pin;
- and
- a grip safety configured to prevent said trigger from engaging said sear absent a firing grip on said firearm and comprising a complementary arresting surface adjacent said hammer when said hammer is in a cocked position;
- and wherein
- said arresting surface and said complementary arresting surface become positively engaged when said grip safety is in a safe position and said hammer rotates in said first direction, thereby preventing said hammer from impacting said firing pin.
A firearm comprising:
- a firing pin;
- a hammer spring;
- a hammer biased by said hammer spring to rotate in a first direction to impact said firing pin, said hammer including a first arresting surface and a second arresting surface;
- a sear operative to engage said hammer such that said hammer is prevented from rotating in said first direction toward said firing pin;
- a trigger operative to disengage said sear from said hammer, allowing said hammer to rotate in said first direction toward said firing pin;
- a thumb safety switchable between a safe position and a firing position, a portion of said thumb safety positioned to prevent said sear from disengaging said hammer when said trigger is depressed, said thumb safety including a first complementary arresting surface;
- and
- a grip safety configured to prevent said trigger from engaging said sear absent a firing grip on said firearm, said grip safety including a second complementary arresting surface adjacent said hammer when said hammer is in a cocked position;
- and wherein
- said first arresting surface and said first complementary arresting surface engage one another when said safety is in said safe position and said hammer rotates in said first direction, preventing said hammer from impacting said firing pin;
- or
- said second arresting surface and said second complementary arresting surface engage one another when said grip safety is in a safe position and said hammer rotates in said first direction, preventing said hammer from impacting said firing pin.
