Definitions

  • My invention relates to automatic firearms with the barrel supported in the frame for ready exchange.
  • the -means for supporting the barrel are so arranged on the barrel and the frame that when the barrel is mounted in place on the frame, they interlock and lock the barrel on the frame, while, when the barrel shall be exchanged, they form an abutment for the tilting of the barrel about the point of support near the muzzle, at the same time allowing the barrel to be moved in the longitudinal direction of its axis.
  • the supporting and locking means also serve to guide the barrel.
  • FIG. 1 is a side elevation, partly in axial section, of the frame and the barrel mounted therein.
  • Fig. 2 is a similar View illustrating the way in which the barrel is removed from the frame.
  • Fig. 3 is a cross section, drawn to a larger scale of the frame and barrel on the line III-III in Fig. 1.
  • I is the barrel and II is the frame.
  • 3 are ribs on the breech end of the barrel extending at right angles to the barrel axis and 4
  • I are notches in the breech end of the movable breech case 5 mounted in the frame I I, which notches extend in parallel to the ribs 3 on the barrel.
  • I3, I3 are a pair of ledges on the inner sides of the forward end on the frame I I, said ledges extending in parallel to the barrel axis on either side of the barrel.
  • Ib are pairs of lugs mounted on the barrel and extending substantially at right angles to and above and below the barrel axis, respectively, said lugs being spaced to embrace the ledges I3 on the frame, when the barrel is mounted in the frame.
  • the lower lugs Illa are arranged forward of the upper lugs Ib.
  • I6, I6 are a pair of vertical projections mounted in spaced relation on the cross piece I'I connecting the two walls of the frame II and I5 is a lug extending downwardly from the bottom of the barrel and fitting in between the pair of ledges I6.
  • the lugs lila and Ilb are arranged in staggered relation so that the front ends of the lugs Illb are spaced the distance e from the rear ends of the lugs Illa.
  • the 5 breech end which is interlocked with the body of the arm or the movable breech by means similar to those shown in French patent specication No. 733,153, is unlocked and the muzzle end is depressed and tilted about the forward bottom 1 edges I8 of the lugs IIlb resting on the ledges I3, until the ribs 3 are free of the notches 4, the breech end 0I the barrel moving in the direction of arrow p, whereupon the barrel can be pulled l5 out in longitudinal direction as indicated by the arrow q, being thus disengaged from the ledges I3,
  • the means for supporting the barrel in the frame according to this invention may be applied to iirearms of widely different types with stationary as well as with sliding barrel.
  • the means for supporting the barrel between the breech and muzzle ends may form guides for the movable barrel.
  • a gun body formed with an axially extending recess, a barrel seated in said recess, interlocking means on said body and the breech end of said barrel to hold said breech to said body with its breech end supported for ready removal of the breech end of said barrel in vertical direction, two inwardly directed horizontal ledges facing each other on the inner walls near the muzzle end of said recess, and two pairs of outwardly directed horizontal ledges on said barrel, one pair extending above, the other below the ledges xed to the inner walls of said recess, when the barrel is seated in said recess, said pairs of ledges being arranged in staggered relation, the lower pair extending forward of the vertical plane containing the front edge of the upper pair.
  • means for centering the barrel on the bottom of the body comprising a vertically extending ledge on one and a pair of spaced vertically extending ledges on the other of the coacting parts, said three ledges being arranged to interlock when the barrel is seated in the gun body.
