Definitions

  • the invention relates to automatic repeating guns by means of which a plurality of cartridges may be shot without removing the gun from the shoulder the different motions being automatically obtained by means of the recoil of the gun.
  • the gun In order to decrease the length and the weight of the gun, it is designed so that the recoil of the barrel takes place, according to the invention, above the magazine.
  • the gun is provided with a sliding barrel, the magazine is disposed in the same position as is the case in a fixed barrel gun, that is to say the forward part of the magazine is almost in the same plane as the edge of the barrel when the gun is in a position o-f rest.
  • the invention provides that return of the bolt, displaced When the gun is fired, by the recoil of the barrel above the magazine, takes place only when the barrel is returned to its initial position.
  • the bolting is effected by means of a lever which serves in addition to separate the bolt from the sliding breech, when the gun is fired.
  • Figures 1 and 2 are respectively vertical, and horizontal fragmentary sections of a gun showing the position of the parts, when the gun is iiring.
  • Figures 3 and 4 are respectively vertical and horizontal fragmentary sections of a gun showing the position of the parts, when the recoil of the barrel is almost terminated.
  • the bolting is obtained by means of a projection or nose 2a of the bolt 2 being introduced into a notch 3a of the sliding breech at the extremity of which the barrel 4 is aiiixed.
  • the bolting is completed by a lever 5 the extremity 5a of which is wedged between the bolt and the sliding breech 3.
  • the barrel 4 and the sliding breech move simultaneously back, without unbolting.
  • the lever 5 which is pivoted on a xed point of the arm is pushed by the rear part 3b of the sliding breech and pivots in the direction of the arrow.
  • the lever 5 is dis- 5 posed in front of a lateral groove 1 of the bolt (see Figs. 3 and 4).
  • the shoulder 8 mounted on the' rear part of the bolt slides on the shoulder 9 disposed on the breech-chamber 6.
  • the bolt is 10 shifted into the axis of the barrel and is unbolted.
  • the barrel and the sliding breech are returned to their 25 initial position under the action of a spring (not shown).
  • a spring (not shown)
  • the bolt may be stopped in its extreme rear position, as long as the barrel is not returned to its initial position.
  • This device may 30 be constituted by means of a rod displaced by the barrel and which acts, for example, on a spring-p'awl mounted in the path of the bolt.
  • the bolt comes forward under the ac- 35 tion of its spring, (not shown).
  • the bolt When it is above the magazine I0, it effects the advance of a cartridge from the magazine and introduces it into the barrel.
  • the lever 5 engages the lever 5 by means of the rear edge 'la of the groove l. 40
  • An automatic repeating gun having a barrel adapted to recoil through a short distance, a 50 v breech movable with said barrel, a laterally shiftable bolt slidably mounted in said breech, a lever pivoted on a fixed part of said gun and wedged in position between one side of the bolt and breech when the breech is locked, means on the 55 breech for shifting said lever, one side of said bolt having a lateral notch provided therein near the rear and in front of which said lever is placed by the breech after a short recoil of the barrel, and a longitudinally inclined projection provided on the face of the bolt opposite said lateral notch adapted near the end of the recoil of the barrel to cooperate with a xed cam surface provided on the casing of the breech to unbolt the bolt and breech.
  • An automatic repeating gun comprising a breech casing, a breech slidably mounted therein, a barrel affixed to said breech adapted to recoil through a short distance upon discharge, a maga- Zine positioned under said breech casing and communicating therewith, a bolt slidably mounted in said breech against vertical movement,'the rear portion of said bolt being formed to provide for lateral movement in said breech, one side of the interior of said breech having a recess formed therein, a lateral projection formed on one side of the bolt adapted to enter the recess in the breech to lock the bolt to the breech, a cam formed on the side of the bolt carrying the projection, cam means provided on the breech casing adapted to cooperate with the bolt cam to laterally shift the bolt near the end of the recoil to remove the projection from the recess in the breech, and wedging means adapted to enter between rearward portions of the breech and bolt when the breech is
