Definitions

  • This invention relates to improvements in folding stock for automatic firearms, and has more particular reference though without limitation to the class of weapons known as machine carbines, and the object of the invention is to provide carbines of the above type with a hinged and foldable butt capable of extension rear of the carbine for operative use, but collapsible at will and foldable about the under side of the weapon with no loose part or parts extending beyond the confines of the weapon itself.
  • a further object of the invention is to so devise the said butt that the operation of opening to operative position and folding to an inoperative condition can be achieved with the minimum of efiort and time, and of providing a butt that when extended is rigid in all directions.
  • a locking device is provided forming part of or attached to the end cap or recoil spring retainer, the latter being capable of small movement axially of the spring casing, the main recoil spring automatically locking said cap to the butt, and means whereby said cap after engagement is prevented from subsequent movement except at will.
  • the invention consists of an articulated triangular butt for machine carbines and the like comprising a forked compound upper main member pivoted to the Weapon at the rear of the pistol stock and adapted in its operative position to engage with and be locked to the carbine end cap, a strut hinged to said main member intermediate its length, a butt plate hinged to said strut and urged under spring pressure to engage at its end remote from its pivot the terminal of the upper main member and be locked thereto.
  • the carbine end cap .with its butt locking device is fixed to the spring casing with a bayonet joint.
  • the end cap has sulficient axial movement, against the recoil spring pressure, to enable the lugs on the forked main member to be raised to the required position and locked therewith by the re- 2 turn movement of the end cap under the recoil spring pressure.
  • An independently operated locking means prevents axial movement of the end cap unless desired.
  • the butt strut is provided with a spring-loaded plunger engaging the tail of the butt plate, said plunger carrying a hook pin capable of snap locking the butt in its folded condition to the forward end of the barrel casing of the carbine.
  • Fig. 1 is a-part sectional elevation of a machine carbine fitted with the folding butt in its extended or operative position

  • the carbine in the position shown in Fig.2: when; the folding butt is swung into, its forwardiriopr is available.
  • the butt formed as a skeletonised entity possesses but little weight, does not upset the balance of the weapon in use, and is, moreover, capable of being folded within the confines of the gun so that no protruding part occurs when the butt is folded into its inoperative position.
  • a pair of separat lugs 3la may be fitted to the forked mime of: the member F and arranged to engage im notches in the rear side of the lug attached to erative position the strut Guestsr-netweeruthe'.”
