Definitions

  • the accompanying drawing represents an example of a breech apparatus according to the invention applied to an automatic firearm with sliding barrel.
  • the three construc- 30 tions show in perspective the apparatus partly in section respectively with the breech locked and in two intermediate positions during the recoil of the barrel after firing.
  • a is the casing of the weapon formed as a hollow cylinder.
  • the breech sleeve Z) coupled with the barrel, which is not shown, is mounted in the casing a so as to be displaceable but not rotatable.
  • the breech piece Z is longitudinally displaceable in the breech sleeve b and projects out of the ring c.
  • the breech piece is guided rectilinearly in the casing slot al and cannot, therefore, rotate in the casing. It is driven forward in known manner by a mainspring which at the same time acts as the means for moving the barrel forward.
  • the breech piece al has segmental collars d1 which engage between similar collars 02 on the ring c and lock ⁇ these members together.
  • the ring c terminates at the rear in two oppositely disposed lobes c3, 04, a similarly. directed wedge shaped surface c5 or c6 of which co-operate with surfaces cl2, cl3 on the breech piece d.
  • the surfaces 05, 06, the collars c2 of the ring 0, the co-operating surfaces cl2, d3 and the collars d, of the breech piece Z are so relatively arranged, that the surfaces 05, c6 of the ring o only come into engagement with the co-operating surfaces d2, da of the breech piece when the collars c2 are out of engagement with the collars all.
