Definitions

  • This invention relates to operatinghandles of the breech-bolt of firearms.
  • the handles of this kind heretofore known were rigidly secured to the breech, while the handle according to my present invention is capable of performing a relative movement with regard to the breech.
  • the reason for this arrangement is to effect proper engagement or disengagement between the breech or single parts thereof and other elements of the gun in a simple way, such engagement or disengagement being simultaneous with the forward or rearward movements of the breech-bolt.
  • Fig. 1 is a longitudinal sectional view of one part of the breech-bolt. the operatinghandle being pivotally attached to the same.
  • Fig 2 shows a modification in a sectional view; the Operating handle in this case being pivotally secured to an opening-bar attached to the breech.
  • the operating-handle 1 is pivotally attached to the breech-bolt 3 by means of a pivot 2.
  • the operating-handle 1 is capable of being slightly swung by the provision of a split 4 left be ween the projection 13 of the coupling lever 7 and the striking-face 6 of the breech-bolt.
  • the operating-handle 1 rests in front, at 5, against the breechbolt, and behind at 20 against the pro jection 1.3 so that when the operatinghandle is being swung its forward move ment is limited at whilst its rearward movement is limited at 6.
  • Pivoted on pin 2 there is a coupling-lever 7 interlocking the breechbolt with one of the rigid parts, say with part 8 of the firearm.
  • the coupling-lever 7 has a tappet 9 subject to the pressure of the firin -spring 12.
  • the action of spring 12 is transmitted to tappet 9 by means of a pressure ring 10 put on the firing-pin 11 and forming the back support of the spring 12.
  • the operating-handle 1 is pressed forward by the pressure-ring 10 subject to the action of the firing-spring 12 so that the operating-handle 1 rests in its normal position against the breech-bolt 3 at 5.
  • the operating handle 1 is also enabled to be swung, and is pivotally attached to the closing-rod 3.
  • the tappet 9 and projection 13 of the coupling-lever 7 act in the same manner as described in connection with Fig. 1.
  • the tappet 9 is subject to the pressure of spring 16 whereby the action of the latter is trans mitted to the tappet 9 by pin 17.
  • the coupling lever 7 is able to be interlocked with the movable rod 18 by means of the curved surface 14 in the same manner as in the construction described in connection with F 1g. 1 with the rigid part 8 of the gun.
  • a firearm the combination of a breech-bolt, an operating handle therefor swingably connected to said breech-bolt, a coupling member movably; connected to said operating handle for coupling the same with a part of the firearm, a pivot pin pivotally connecting the handle and the coupling member with the breech-bolt, said coupling memberhaving-a projection adapted to be engaged by the handle for operating the coupling member in one direction, and a spring for a'ctuatifigthe coupling member in the opposite direction.
  • a breech-bolt an operating handle therefor swingably connected to said breech-bolt, a coupling member movably connected to said operating handle for coupling the same with a part of the firearm,-means on said handle for operatlng sald coupling member 111 one direction a firing spring, means for transmittlng the action of sald firing spring to the coupling member in the opposite direction independently of the sw nging movements of the handle relatively to the breechbolt.
