Definitions

  • the present invention relates to a device for supplying ammunition to an automatic weapon movable in translation relative to a fixed provider.
  • the problem is to bring ammunition from a storage location and a fixed provider relative to the frame of the weapon, to the latter movable in longitudinal translation due to its recoil.
  • Patent EP-A- 0 388 301 which forms the base of the preamble of independent claim 1, describes a device for supplying ammunition of an automatic weapon between a stationary provider and the breech of the mobile weapon according to a movement of back and forth.
  • the structure adopted consists of providing a helical ramp with variable pitch along a transfer arc, but is characterized by the absence of a slide taking charge of the ammunition.
  • Patent DE-A-1 965 1445 describes a weapon in which the ammunition supply system allows automatic loading at the point of return of the receding mass. This weapon does not include any slide provided with means for gripping a munition and equipped with a guide means.
  • the present invention aims to provide a supply device for bringing a munition in the firing position from the fixed provider.
  • the subject of the invention is a device for supplying ammunition to an automatic weapon movable in translation relative to a fixed provider, comprising at least one slide provided with means for gripping a munition and first means guide means for bringing the slide from a random longitudinal position relative to the weapon, to a predetermined longitudinal position relative to the weapon, second guide means for bringing the slide from a random longitudinal position relative to the provider at a predetermined longitudinal position relative to the provider, so as to cyclically return the slide from its weapon supply position to the stationary provider of ammunition, characterized in that the second guide means may comprise a ramp and a counter-ramp integral with the supplier and gradually approaching from the weapon to the supplier, and a roller mounted on the slide to move between the two ramps, the distance between the ramp and the counter-ramp at the level of the provider being substantially equal to the diameter of the roller.
  • said first guide means comprise a ramp and a counter-ramp secured to the weapon and progressively approaching from the provider to the weapon, and a roller mounted on the slide to move between the two ramps, the longitudinal distance between the ramp and the counter-ramp at the level of the weapon being substantially equal to the diameter of the roller.
  • roller can be used for the first and second guide means.
  • Each ramp associated with its respective counter-ramp therefore acts in the manner of a funnel, the roller of the slide occurring between the ramp and the counter-ramp in a random longitudinal position and being brought into a predetermined position relative to either the weapon either to the outfitter according to the phase of the cycle in question, namely either the feeding phase or the return to the outfitter phase.
  • the device can comprise, in a known manner, means for feeding the ammunition in an arc, the slides being, according to the invention, arranged on a barrel mounted to rotate around the axis of said arc.
  • the ramps can be helical ramps, the counter-ramps being circular.
  • the supply means may in particular comprise a plurality of stars mounted to rotate on the axis of said arc of a circle.
  • At least one push finger for bringing a munition from its predetermined longitudinal position to its firing position.
  • FIG. 1 represents a weapon comprising, in a known manner, a fixed frame symbolized by the reference 1, a screw 2 for controlling the breech, a breech 3 and a set of stars 4 making it possible to supply the breech 3 with ammunition from 'A provider (not shown) secured to the frame 1.
  • the star mounting shaft 5 4 also carries a barrel 6 on which four sliders 7 are slidably mounted in the longitudinal direction.
  • the slides 7 comprise at one of their ends a roller 8 with an axis perpendicular to the axis of the shaft 5, and at the other end a projection 9 in the form of a hook in an arc of a circle capable of engaging. in a groove 10 of corresponding shape made in the socket of a munition 11.
  • the device according to the invention furthermore comprises a helical ramp 12 and a circular counter ramp 13 integral with the receding part of the weapon, as well as a helical ramp 14 and a circular counter-ramp 15 secured to the fixed frame 1.
  • the ramps 12 and 13 approach each other from the provider to the weapon, and in the same way the ramps 14 and 15 approach each other from the weapon to the provider.
  • the final distance between the ramps 12 and 13 on the one hand and 14 and 15 on the other hand is substantially equal to the diameter of the rollers 8, so that when a slide arrives at the end of its path between the ramps 12 and 13 , it is in a determined longitudinal position relative to the weapon and that, likewise, when it reaches the end of its path between the ramps 14 and 15, it is in a determined position relative to the provider.
  • the shaft 5 simultaneously drives the stars 4 and the barrel 6.
  • the slide 7a located opposite the cylinder head 3 supports ammunition at the provider. At this time, it is in a random longitudinal position relative to the weapon.
  • the longitudinal position 7b of the slide is random with respect to the ammunition provider.
  • the rotation of the barrel 6 then causes it to come into contact with the ramp 14 secured to the frame 1 of the weapon, this ramp 14 finally returning it to the position 7a determined longitudinally relative to the provider where it can take charge of another ammunition.
  • the device according to the invention therefore makes it possible to bring ammunition from the stationary provider to the mobile weapon using the slides 7, then to bring the latter to the provider, the relative positions of the provider and the 'weapon being any.
