https://patentgrep.com/patent/US4395839A ## CPC - F41A 17/72: trigger-operated, i.e. the movement of the trigger bringing a firing-pin safety into inoperative position during the firing - F41A: FUNCTIONAL FEATURES OR DETAILS COMMON TO BOTH SMALLARMS AND ORDNANCE, e.g. CANNONS; MOUNTINGS FOR SMALLARMS OR ORDNANCE ## Abstract In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin. ## Claims ### Claim 1 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said locking device including at least two movable elements one of which is located in front of the firing pin and frictionally connected to the trigger and another of which is engageable with the firing pin. ### Claim 2 (depends on 1) A firearm as in claim 1 wherein said other element is pivoted intermediate its ends to the barrel for swinging movement in a vertical plane transverse to the axis of the barrel. ### Claim 3 (depends on 1) A firearm as in claim 1 including a spring for biasing the locking device toward its locking position. ### Claim 4 (depends on 1) A firearm as in claim 1 wherein the locking device includes a vertically movable slide having a lower end engageable with the trigger, said slide being positioned laterally of the axis of the barrel. ### Claim 5 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, said trigger having a recess therein, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said locking device including an element engageable in the recess in the trigger so as to be movable with the trigger. ### Claim 6 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said locking device including a projection engageable with the forward end of the firing pin. ### Claim 7 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said locking device including a vertically movable slide engageable with the trigger and a longitudinally movable rod having a forward end engageable with the slide and a rear end in engagement with the firing pin such that the rod and firing pin move together. ### Claim 8 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said locking device including a pivoted lever engageable by the trigger and a slidable rod engageable at one end with the pivoted lever and at its opposite end with the firing pin. ### Claim 9 (depends on 8) A firearm as in claim 8 wherein said pivoted lever is bow-shaped and is arranged in a recess provided in the barrel above and laterally of the axis of the barrel. ### Claim 10 In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, the locking device including a lever pivoted intermediate its ends for swinging movement in a vertical plane lying parallel to the axis of the barrel, the lever being positioned in a recess extending parallel to the axis of the barrel and a vertically movable element engageable with one end of the lever and with the trigger. ### Claim 11 In a firearm having a barrel with a drilled hollow space for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device having at least one movable element for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin, said movable element being located within said barrel in front of said firing pin, frictionally connected to the trigger and surrounding at least partly said drilled hollow space for receiving a cartridge. ### Claim 12 (depends on 11) A firearm as in claim 11 including a biasing spring for pushing the movable element of said locking device toward its locking position.
