Definitions

  • This invention relates to machine guns and automatic small arms of the gas operated type in which the operating piston connected to the breech mechanism moves rearwardl against the resistance of a helical recoil spring which reacts to move the mechanism to the forward oriiring position.
  • the chief object of the present invention is to provide improved constructions of machine guns and automatic small arms of the above type inwhich a, buiier spring is provided or absorbing excess recoil energy in the moving parts.
  • Figr' 1 is a vertical longitudinal section of the rear part of a gun provided with one constructional form of our improvements
  • Figure 2 is a longitudinal section of another constructional form of our improvements.
  • VA is the gun barrel
  • B is part of the gun' casing
  • C is the gas operated iston rod
  • D is the striker post carried by t e said piston rod
  • E is the breech bolt which is rocked into and out of its engaging position with a portion B2 of the gun casing by the co-operation of projections D1 on the striker post with inclined or cam surfaces E1 in the bolt as is well understood
  • F is the recoil spring
  • G is the buier spring disposed behind and in line with the recoil spring F.
  • the rear part of the recoil spring F surrounds a member F1 slidably mounted in a part BL attached to the gun casing; the rear end of this spring bears against a collar F2 on the said slidable member and its front end bears against .
  • the rear end of the operating piston rod C which has a key CX on each side engaging in a guideway C1 in the gun casing.
  • member F1 has a rearward stem F3 which passes through a hole in the rear wall of the part B1 and the buier spring G, which is made of stouter construction than the recoil spring F, is disposed around this stem with its front end in contact with the rear surface of the collar F2 and its rear end in contact with the front surface of the rear wall of the part B1.
  • the front part of the member F projects a suitable distance beyond the front of the part B as shown.
  • the rear end of the recoil spring F is disposed within the buffer spring G and bears against a collar H on a guide rod H1 for the former spring, the collar in turn bearing against the rear wall of the aforesaid part B1.
  • the rod H1 lits within a hole in the piston rod C and the front end of the spring F enters the said piston rod and bears against a shoulder'as shown.
  • the rea-r end of the buffer spring G is in contact with the rear Wall of the part B1 and its front end bears against a collar or sleeve H2 slidablv carried by the said part with its front portion projecting there rom as shown.
  • ide rod for said recoi spring the rear -en of said 'rod bearing against a part attached to theun casing, e coller on seid rod the rear en of seid recoil spring bearing against'said coller, i@ and e sleeve slidabl7 carried by seid part end bearin against said hurler spring which is arrange around the reer end of the recoil spring and with its rear end bearing against said part, the front end of seid sleeve prol@ jecting beyond said per@ so that it cen be moved rearward by the rear end of the rod cf seid operating piston in order to compress -the buffer spring.
