Definitions

  • the safety device may be used in connection with all-kinds of automatic fire arms,
  • the trigger tongue g which is, against the action of; the, spring f ,-turned about the pivot pin carried bythetrigger f and moved out of the path of the arn e of the tension member c, It is ,now, impossible to influence the percussion device by thetrigger. device. If then the trigger is drawn back, the tongue g turns downward behind the ann a ofthe tension member e and no release .ofthetensioned cock .dloeeurs. g;
  • the force of the closing spring a is transmitted to the safety member h by the movable bolt 0 of the closing spring acting upon the breech portion (1.
  • this may be effected directly by the breech portion a, or the closing spring may be caused to act upon the safety lever h by way of the second bearing c of the closing spring which inthis 'case would then also be made movable.
  • thegclosing spring weakens or breaks which, however, allows firing even if the breech isnot perfectly closed.
  • thesafety lever could be causedto directly lockthe trigger or percussion device in the manner of the locking members of the ordinary hand actuated safety devices.
  • the safety lever must then be of other construction, for instance, be formed and arrangedas a slide.
  • the fire arm may have, besides the safety device according to the invention, also a hand actuated safety device in which case, for the purpose of simplifying and reducing the single parts, both devices are preferably organically connected to each other.
  • a locking member for the trigger device or the percussion device may, for instance, be controlled automatically by the force of the closing spring as well as by hand by means of a suitable handle.
  • a safety device for automatic fire arms a breech, a closing spring for sa1d breech, a percussion device, a safety device cooperating with said percussion device and a but being, under the influence of said second mentioned spring, brought automatically into a locking position preventing the release of said percussion device as soon as the force of said closing spring is reduced below that necessary and admissible for the normal rearward and forward running of the movable masses.”
  • a safety device for automatic fire arms a breech, a closing spring for said breech, a bolt movably arranged in said closing spring, a bearing provided at said bolt, a percussion device, a safety device cooperating with said percussion device and a second spring adapted to influence said safety device, said closing spring influencing said safety device by said bearing acting upon said breech if said breech is perfectly closed only, so that firing is prevented not only if said closing spring is out of order but also, in known manner, if the breech is not perfectly closed.
