Definitions

  • This invention relates'to a safety device for bolt-action .firearms of the type in which the breech bolt is rotatable I and movable endwise.
  • .It- is an object of the invention to provide a reliable and eifective safety device ⁇ ilhich'will lock both the sear j andthebreech bolt of the firearm; Another object is to provide a device of this kind of simple construction and ease of installation.
  • the invention comprises thenovel combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawing, in which: I Fig, l is a brokenview in side elevation of a bolt-action provided fa safety device according. to the invention. Fig.2 shows parts of the action in vertical longitudinal section.
  • Fig/3 is-a transverse section on the line III-III of Fig. 1.
  • the invention is illustrated by way of exampleas incorporated in a sporting rifle action of the well-known Mauser type in which the breech bolt is rotatable and movable endwise', theendwise movement serv- ;ing: to ejectthe spent sh lbreload the chamber and cock the firing member.
  • Fig.1 thebolt is shown in retracted p itionand the safetydevicein its inoperative position.
  • Fig.2- the boltis shown in its foremost or firing posibolt Shaving an integral handle 6 and carrying a shell extractor 7.
  • a rear locking lug 8 projecting downwardly, when the bolt is in firing position, for engagement with a forwardly directed surface 9 provided in casing 1 and adapted to aid in bearing the explosion pressure axially exerted upon the bolt.
  • a firing pin 10 pressed by a helical firing spring 11 and secured to a nut 12 which has :an abutment 13 for cooperation with a cocking tooth 20 on the rear end of a sear which, in known manner, may be resiliently secured to the casing 1.
  • the sear 17 is pivotally connected to the casing by means of a pin 18.
  • a spring 19 in the sear forwardly of pivot pin 18 bears against the casing and urges the opposite rear end of the sear upwardly.
  • the sear is apertured for receiving a trigger which is pivotally secured to the sear by means of a pin 21 and which is formed with a pivot point 16 adapted to abut the portion 2 upon actuation of the trigger.
  • the safety device comprises an elongated upright plate 25 mounted on the brejach'casing at one (the right) side of the sear 17 for slidable movement in the axial direction of the bolt.
  • this plate is provided with upward extensions 26,127.
  • the rear extension 27 is movable in a lateral recess 36 in the tail part 2 and provided with a longitudinal slot 30 for a pin or screw 37 secured to said part 2 of the casing.
  • Fixed to extension 27 is a thumb piece 28 arranged immediately above the tail part 2 beside the breech bolt;
  • The'fore upward extension 26 is movable the plate may, as shown, be reciprocably mounted on the pivot pin 18 by-means of a longitudinal slot 29 provided inthe plate,
  • a snap spring 38 fixed to the bottom side of the casing is adapted to cooperate with a pin 33 mounted .on the safety plate, for keeping said plate either in its forward or inoperative position shown in Fig. 1, or in its rearmost or locking position shown in Fig. 2 (wherein therear part of the safety plate is broken away).
  • this locking part, 32 is constituted by an angular slot 31 -forapin 39 fixed to the rear end of the sear.
  • this pin In the inoperative position shown in Fig. 1 this pin is movable downwardly-in the slot during a firing movement of the -Sea II1 S ald inoperative position of the safety plate the top part of the plate extension 26 is situated in front-of thetpath of the locking lug 8 corresponding to a turning movement of the breech bolt, which consequently, is not obstructed by the safety plate.
  • a partofplate extension 26 is brought into said path of the ..;l l-,lg;8 SO;-aS to "engage-the right side thereof whereby'the breech bolt will become effectively locked in its firing position.
  • the locking part 32 of the safety plate occupies a position immediately below the pin 39,.
  • a firearm comprising in combination: a breech casing, a breech bolt rotatable and axially displaceable in said casing, an integral handle and an integral rear locking lug on said breech bolt, a forwardly directed bearing surface in said casing engageable by said locking lug when the breech bolt is in firing position, a firing member carried by said breech bolt, a sear pivotally mounted on said casing for releasably holding said firing member In its cocked position, a trigger pivotally connected with said sear whereby motion of the trigger rotates the sear to release the firing member, and a manually operable safety member mounted on said casing for movement substantially in the axial direction of the bolt into and out of locking position with respect to the sear, said member in its locking position engaging one side of said lug to lock the breech bolt against rotation when the latter is in firing position.
  • a firearm comprising in combination: a breech casing, a breech bolt rotatable and axially displaceable in said casing, an integral handle and an integral rear locking lug on said breech bolt with the lug projecting downwardly when the breech bolt is in firing position, a forwardly directed bearing surface in said casing engageable by th lug when the bolt is in firing position, a firing member carried by said breech bolt, a scar pivotally mounted on said casing for releasably holding said firing member in its cocked position, a trigger pivotally connected with :said sear whereby motion of the trigger rotates the sear to release the firing member, and a manually operable safety device mounted on said casing at one side of the sear for slidable backward and forward movement into and out of locking position, a rear part of said'device engaging said sear to lock the sear against firing movement and a forward part of said device extending into a slot in said casing to engage one side of said lug to
  • a firearm comprising in combination: a breech casing having a tail portion, a breech bolt rotatable and axially displaceable in said casing, an integral handle and an integral rear locking lug on said breech bolt with the lug projecting downwardly when the breech bolt is in firing position, a forwardly directed bearing surface in the casing engage'able by the lug when the breech bolt is in firing position, a firing member carried by said breech bolt, a sear pivotally mounted on said casing for releasably holding said firing member in its cocked position, said sear being provided at its rear end with a firing-memher-engaging part and a lateral locking projection, a trigger pivotally connnected with said sear whereby motion of the trigger rotates the sear to release the firing member, a finger piece arranged on said tail portion beside the breech bolt, and an elongated safety plate mounted on said casing at one side of the sear for slidable backward and forward movement
  • a firearm comprising a breech casing having an integral portion extending rearwardly, a bolt movable in translation and rotation in said casing, a lug formed on said bolt and arranged to depend therefrom when the said bolt is in firing position, a firing pin in said bolt, a sear pivotally mounted on said casing to releasably hold said firing pin in battery position, a trigger pivotally secured within said sear, whereby motion of said trigger rotates said sear to release said firing pin, and a safety device comprising a plate member slidably mounted on said casing at one side of said sear, a slot formed in said plate substantially in the form of an inverted L, a pin fixed to said scar and penetrating said slot whereby upon sliding said plate to safety inoperative position the pin moves vertically in the slot during sear pivoting and upon sliding said plate to safety operative position vertical motion of the pin and sear pivoting is prevented.
