Definitions

  • An ammunition belt feeder for an automatic weapon having a housing with a movable feed sprocket mounted therein for an ammunition belt and an intermittently-operated drive mechanism with a coupling for conmeeting and disconnecting the feed sprocket and at least two belt feed apertures in the housing and the direction of movement of the feed sprocket is constant.
  • the invention relates to an ammunition belt feeder with intermittently-driven feed sprocket for feeding cartridge ammunition in belts to automatic weapons.
  • a belt feeder for automatic weapons has already been proposed in which it is possible to feed a belt in from two opposite sides of the feeder.
  • the ammunition belts require different belting, designated as leftor right-hand belting, and it is also necessary to exchange switching means in the belt feeder in order to transfer from leftto right-hand feed.
  • a belt feeder according to the invention differs from those hitherto known in that the transition from one type of ammunition to another or to the feeding of a belt in another feed aperture is possible without changing the switching means in the belt feeder, without the use of tools, and without requiring different belting.
  • the feeding of the ammunition belts is further facilitated according to an advantageous sub-feature of the invention by providing the guide members on the outside of flaps which can be pivoted against spring pressure into the belt feeder.
  • the inner surface of the flaps may form an arc-shaped guide path for the cartridges of a belt introduced through a preceding feed aperture.
  • An effective reinforcement of the guide members is thereby achieved, so that the latter can themselves consist of relatively thin sheet-metal plates which are connected, for example by spot-welding, to the flaps which are preferably also made of sheet-metal.
  • FIG. 5 is a simplified cross-section along the line V-V of FIG. 1, and
  • a feed sprocket formed of two star-wheels 10 intermittently conveys the cartridges in a cartridge belt int-roduced into the feed aperture 3 towards the weapon 2 where they are pushed out of the belt by a lug 11 situated on a reciprocating bolt and into the weapon through a front aperture 12.
  • the housing has a slot 12 on the side nearest the weapon.
  • the housing of the belt feeder may be rectangular as in FIG. 2 or cylindrical as in FIG. 6.
  • the method of operation of the belt feeder is as follows:
  • the intermittent feed is effected via a ratchet coupling 20 which couples the pinion 19 with a coupling sleeve 21 arranged non-rotatably but resiliently displaceable in a longitudinal direction in the hub 13.
  • the coupling sleeve 21 has a pinion-toothed section 21.
  • the spring drum 17 is supported on a spindle 22 fixed in the end wall so that it can rotate, to an extent which is determined by stops 23 and 24, against the tension of a spiral spring 25.
  • the inner end of the spring 25 is attached to the spindle 22 while the outer end of the spring is fixed to the spring drum 17.
  • guide members are provided by means of which the belt links are guided centrally between the star wheels 10.
  • two spaced guide edges 33 are provided (FIG. 2) between which the belt claws 9 are fed to the star wheels 10, the claws sliding on their outer rims 9 along the edges 33.
  • spring-biased retainers 34 are provided which reach into the feed aperture 3 and act on the ends 9" of the first belt link. The retainers are then pushed up by the first cartridge of the belt. The retainers 34 therefore only effect the proper introduction of the first belt link, which contains no cartridge.
  • guide members which can be pivoted into the inside of the belt feeder.
  • These guiding members consist, in each case, of a flap 36, which is held in the position shown in FIG. 2 by means of a spring 38 wound round the pivotal axis 37 of the flap.
  • the flap made of sheet-metal, forms with its inner surface an arc-shaped guide path for the cartridges of a cartridge belt introduced through one of the preceding feed apertures.
  • the flaps have guide edges 39 between which the rims 9" of the belt links are guided when a belt is introduced through one of the said feed apertures. The flap is thereby pivoted by the belt claws 9 into the inside of the belt feeder, between the feed star wheels 10.
  • An ammunition belt feeder for an automatic weapon comprising in combination, a housing, a movable feed sprocket mounted in said housing for advancing an ammunition belt through the feeder, an intermittently-operated drive mechanism, a coupling for connecting and disconnecting said feed sprocket and said drive mechanism, at least two belt feed apertures in said housing adjacent said feed sprocket for guiding ammunition belts to said feed sprocket and positioned relatively to the latter in such manner that the direction of movement of the feed sprocket is constant irrespective of which feed aperture is employed to guide a belt to the feed sprocket, guide members on said housing adjacent said feed apertures for guiding cartridges in a belt, and means for resiliently supporting the guide members in a plane normal to that of a belt when in the feeder, and the guide members being spring-biased flaps pivotally mounted upon the housing and pivotable against said spring-biasing into the interior of said housing, said flaps also having a surface forming an arc-shaped guide path for cartridges of a belt
