Safety apparatus for a gun triggering mechanism

Claim 2

In a gun triggering device having a cockable firing pin, means including at least one movable element for releasing said firing pin, and safety means for preventing accidental release of said firing pin, the improvement wherein said safety means includes: a mass part rotatably mounted at a point spaced from its center of mass; said mass part being normally spring-biased to a rest position, but movable to a non-rest position; said mass part having a stop member which, when said mass part is in said rest position, is aligned with a recess formed in said movable element, thereby permitting movement of said element toward said stop member for releasing said firing pin; said stop member, when said mass part is in a non-rest position, being unaligned with said recess, thereby preventing movement of said element toward said stop member for releasing said firing pin.

Claim 3

Apparatus according to claim 1 wherein said releasing means includes: a trigger sear; a spring-biased toggle linkage connected to said trigger sear; said element constituting a link in said toggle linkage; and a trigger engageable with said toggle linkage to deflect said toggle linkage against its spring bias, toward said stop member to cause said trigger sear to release said firing pin.

Claim 4

Apparatus according to claim 2 wherein: a safety cross bar is rotatably mounted within a housing of said triggering device; said cross bar having opposed first and second supporting surfaces; said cross bar being rotatable to a safety position wherein said first supporting surface is positioned adjacently below said trigger sear, and said second surface engages said mass part to move said mass part to a non-rest position.

Claim 5

Apparatus according to claim 1 wherein said releasing means further includes: a trigger having a slot formed therein; a fixed pin positioned within said slot permitting forward shifting movement of said trigger with respect to said pin; a spring connected to said trigger, which spring being at rest when said trigger is in its normal position, and being biased when said trigger is in a forwardly shifted position; said trigger including an extension; an abutment positioned adjacent said extension whereby, upon forward shifting of said trigger, said extension engages and is releasably held by said abutment.

Claim 6

Apparatus according to claim 4 wherein: said abutment has a supporting surface for engaging said extension; said abutment being adjustable to vary the inclination of said surface.

Claim 7

Apparatus according to claim 4 further including: an adjustably mounted screw for limiting the forward shifting movement of said trigger.

Claim 8

In a gun triggering device having a cockable firing pin: a firing pin releasing means including: a trigger sear; a spring-biased toggle linkage connected to said trigger sear; a trigger engageable with said toggel linkage to deflect the latter against its spring bias to cause said trigger sear to release said firing pin; said trigger having a slot formed therein, said slot being pivotal and forwardly shiftable on a fixed pin positioned in said slot; a spring connected to said trigger, said spring being at rest when said trigger is in its normal position, and being biased when said trigger is in a forwardly shifted position; said trigger including an extension; an abutment positioned adjacent said extension whereby, upon forward shifting of said trigger, said extension is engaged and releasably held by said abutment; said abutment having a supporting surface for engaging said extension; said abutment being adjustable to vary the inclination of said surface; and an adjustably mounted screw for limiting the forward shifting movement of said trigger; and a safety means for preventing accidental release of said firing pin including: a mass part rotatably mounted at a point spaced from its center of mass; said mass part being normally spring-biased to a rest position, but movable to a non-rest position; said mass part having a stop member which, when said mass part is in its rest position, is aligned with a recess formed in a link of said toggle linkage for permitting said toggle linkage to deflect toward said stop under the influence of said trigger; said stop member, when said mass part is in a non-rest position, being unaligned with said recess for preventing deflection of said toggle linkage to release said firing pin; a safety cross bar having first and second supporting surfaces and being rotatable to a safety position wherein said first supporting surface is positioned adjacently below said trigger sear, and wherein said second surface engages said mass part to move the latter to a non-rest position.

Claim 9

In a gun triggering device having a cockable firing pin: a firing pin releasing means including: a trigger sear; a spring-biased toggle linkage connected to said trigger sear; a trigger engageable with said toggel linkage to deflect the latter against its spring bias to cause said trigger sear to release said firing pin; said trigger having a slot formed therein, said slot being pivotal and forwardly shiftable on a fixed pin positioned in said slot; a spring connected to said trigger, said spring being at rest when said trigger is in its normal position, and being biased when said trigger is in a forwardly shifted position; said trigger including an extension; an abutment positioned adjacent said extension whereby, upon forward shifting of said trigger, said extension is engaged and releasably held by said abutment; said abutment having a supporting surface for engaging said extension; said abutment being adjustable to vary the inclination of said surface; and an adjustably mounted screw for limiting the forward shifting movement of said trigger; and a safety means for preventing accidental release of said firing pin including: a mass part rotatably mounted at a point spaced from its center of mass; said mass part being normally spring-biased to a rest position, but movable to a non-rest position; said mass part having a stop member which, when said mass part is in its rest position, is aligned with a recess formed in a link of said toggle linkage for permitting said toggle linkage to deflect toward said stop under the influence of said trigger; said stop member, when said mass part is in a non-rest position, being unaligned with said recess for preventing deflection of said toggle linkage to release said firing pin; a safety cross bar having first and second supporting surfaces and being rotatable to a safety position wherein said first supporting surface is positioned adjacently below said trigger sear, and wherein said second surface engages said mass part to move the latter to a non-rest position.

Claim 10

In a gun triggering device having a cockable firing pin, means including at least one movable element for releasing said firing pin, and safety means for preventing accidental release of said firing pin, the improvement wherein said safety means includes: a mass part rotatably mounted at a point spaced from its center of mass but movable to a non-rest position; and cooperative means on said mass part and movable element for permitting said movable element to release said firing pin when said mass part is in its rest position, and for preventing said movable element from releasing said firing pin when said mass part is in a non-rest position.

Claim 11

In a gun triggering device having a cockable firing pin, means including at least one movable element for releasing said firing pin, and safety means for preventing accidental release of said firing pin, the improvement wherein said safety means includes: a mass part rotatably mounted at a point spaced from its center of mass but movable to a non-rest position; and cooperative means on said mass part and movable element for permitting said movable element to release said firing pin when said mass part is in its rest position, and for preventing said movable element from releasing said firing pin when said mass part is in a non-rest position.

Claim 12

Apparatus according to claim 8 wherein said cooperating means includes: a recess formed in one of said mass part and movable element; and a stop member formed in the other of said mass part and movable element; said stop element and recess being aligned when said mass part is in said rest position, and being disaligned when said mass part is in said non-rest position.
