Abstract
Abstract A safety shaft, pivotable between lock and release position extends transverse to the firing pin to expose the end of the firing pin when in the release position and having its outer surface engaging the hammer when in the lock position to prevent the hammer from striking the firing pin. An intermediate lever has one end engageable by the safety shaft when it is moved to the lock position so that pivoting of the intermediate lever causes a tab on its other end to move the trigger rod from operative engagement with the lower end of the hammer. At the same time, the tab end of the intermediate lever engages a hammer lever to move the hammer lever from engagement with a notch on the hammer. The trigger may thus be actuated when the safety is in the lock position but will not cause the hammer to strike the firing pin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
In a firing pin safety device for small firearms, a combination of a pivotally mounted hammer engageable with a firing pin, a pivotally mounted safety shaft having lock and release positions extending transversely to the firing pin and having an opening therein through which the end of the firing pin is exposed to the hammer when the safety shaft is in the release position, the outer surface of said safety shaft engaging said hammer when in the lock position, a trigger rod from a trigger and having means thereon operatively engageable with said hammer, and lever means engageable with said trigger rod and actuated by the pivoting of said safety shaft to the lock position for disengaging said trigger rod and hammer.
Claim 2
Dependent Claim
122 words
In a firing pin safety device for small firearms, a combination of a pivotally mounted hammer engageable with a firing pin, a pivotally mounted safety shaft having lock and release positions extending transversely to the firing pin and having an opening therein through which the end of the firing pin is exposed to the hammer when the safety shaft is in the release position, the outer surface of said safety shaft engaging said hammer when in the lock position, a trigger rod from a trigger and having means thereon operatively engageable with said hammer, and lever means engageable with said trigger rod and actuated by the pivoting of said safety shaft to the lock position for disengaging said trigger rod and hammer.
Claim 3
Dependent Claim
173 words
In a firing pin safety device for small firearms, a combination of a pivotally mounted hammer engageable with a firing pin, a pivotally mounted safety shaft having lock and release positions extending transversely to the firing pin and having an opening therein through which the end of the firing pin is exposed to the hammer when the safety shaft is in the release position, the outer surface of said safety shaft engaging said hammer when in the lock position, a trigger rod from a trigger and having means thereon operatively engageably with said hammer, and means responsive to the pivoting of said safety shaft to the lock position for disengaging said trigger rod and hammer, said means comprising a pivotally mounted intermediate lever having one end engageable by said safety shaft and a tab on its other end engageable with said trigger rod, said intermediate lever being pivoted when said safety shaft is moved to the lock position so that the tab engages said trigger rod to disengage the rod from said hammer.
Claim 4
Dependent Claim
173 words
In a firing pin safety device for small firearms, a combination of a pivotally mounted hammer engageable with a firing pin, a pivotally mounted safety shaft having lock and release positions extending transversely to the firing pin and having an opening therein through which the end of the firing pin is exposed to the hammer when the safety shaft is in the release position, the outer surface of said safety shaft engaging said hammer when in the lock position, a trigger rod from a trigger and having means thereon operatively engageably with said hammer, and means responsive to the pivoting of said safety shaft to the lock position for disengaging said trigger rod and hammer, said means comprising a pivotally mounted intermediate lever having one end engageable by said safety shaft and a tab on its other end engageable with said trigger rod, said intermediate lever being pivoted when said safety shaft is moved to the lock position so that the tab engages said trigger rod to disengage the rod from said hammer.
Claim 5
Dependent Claim
43 words
In a firing pin safety device as claimed in claim 2 wherein said hammer has a first notch at its other end, said trigger rod having a cam tooth operatively engageable and disengageable with said hammer notch by the actuation of the trigger.
Claim 6
Dependent Claim
62 words
In a firing pin safety device as claimed in claim 3 wherein said hammer has a secOnd notch adjacent said other end, a hammer lever engageable with said hammer second notch, said intermediate lever tab simultaneously engaging said trigger rod and hammer lever to disengage said hammer lever from said second notch when the safety shaft is rotated to the lock position.
