Definitions

  • the present invention relates to an automatic weapon, and more particularly such a weapon of the type comprising a feed device and a rotary drum driven in rotation by an external motor, said drum comprising a breech control ramp of closed contour.
  • Such a weapon is known from French patent n ° 76 35638.
  • This weapon comprises a breech secured to a follower member cooperating with the control ramp so as to cause a back and forth movement of the breech when the drum is driven in rotation.
  • the breech therefore moves, from a rear position in which ammunition is supplied to it by the feed device, towards the front, loaded with the ammunition which it engages in the cartridge chamber of the tube. In its most forward position, the breech closes the cartridge chamber and the ammunition is fired. The cylinder head then moves back to its rear position.
  • the present invention seeks to overcome this drawback by providing an automatic weapon with an external motor at a higher rate of fire compared to that of the aforementioned French patent, while limiting as much as possible the increase in weight and power consumed.
  • the subject of the invention is an automatic weapon of the type comprising a feeding device and a rotary drum driven in rotation by an external motor, said drum comprising a bolt control ramp of closed contour, characterized by the fact that it further comprises two follower members cooperating with said ramp and each secured to a respective cylinder head to cause this cylinder head to move back and forth between a feeding position where it is spaced from a chamber respective cartridge and a firing position where it closes this cartridge chamber, and by the fact that the feed device comprises a feed member driven by a continuous rotational movement and two dispensing members driven by continuous movements intermittent rotation, each of the distribution members being arranged to receive, during its shutdown period, an ammunition of the supply member, and to provide, during its subsequent rotation ieure, this ammunition to a respective cylinder head while the latter is in its feeding position.
  • the weapon according to the invention therefore comprises two tubes and two movable breeches.
  • Each of these cylinder heads is driven by a follower member, the two follower members cooperating with the same control ramp.
  • This weapon therefore comprises a single external motor and a single rotary drum.
  • the same external motor can be used to drive two cylinder heads at almost the same speed as it would drive only one.
  • the rate of fire is almost doubled for an increase in minimum weight.
  • said ramp has two parts perpendicular to the axis of the drum, respectively close to and spaced from the cartridge chamber, and two héiicoldaies parts inclined relative to the axis of the drum, this ramp being wound four times on the drum , that is to say that it crosses itself three times, and said follower members being maintained in the same diametrical plane of the drum, each on one side of the axis.
  • each dispensing member has a star-shaped cross section, each star branch having its leading edge, with respect to the direction of movement, shaped to drive the ammunition for the period of movement of said member, and its trailing edge shaped to guide, during its rest period, the ammunition driven by the other member.
  • each distribution member is used both for feeding its breech during its periods of movement, and for guiding the munition guided towards the other breech during its stopping period.
  • the distribution members can be driven by any system with intermittent movements, for example by a malta cross system.
  • these distribution members are constituted by three-pointed stars, they are preferably driven by a Fergusson system with intermittent drive having a cam and two cages, the cam being driven continuously from the external motor, and each of the cages intermittently driving, distribution members.
  • the weapon shown in Figure 1 has two tubes 1 G and 1 D each having a cartridge chamber shown schematically in 2G and 2D.
  • a motor 3 rotates a drum 4 provided with a control ramp 5 which will be described in more detail below.
  • Two cylinder heads 6G and 6D are associated with the cartridge chambers 2G and 2D and are carried by cylinder head heads 7G and 7D respectively.
  • Follower members 8G and 8D are mounted on the cylinder head 7G and 7D and cooperate with the ramp 5 to cause the reciprocating movement of the cylinder heads 6G and 6D in the direction of the arrows F1.
  • Figure 4 shows the ramp 5 once developed.
  • This ramp once developed, has two rectilinear parts 9 and 10 which, on the drum 4, are therefore in planes of cross section.
  • the ramp of Figure 4 is wound four times on the drum 4, that is to say that it overlaps itself three times.
  • the cylinder heads 6G and 6D are therefore stationary when their followers 8G and 8D respectively are either in part 9 or in part 10 of the ramp 5.
  • the respective cylinder head When the follower of one of the cylinder heads is in part 9 of the ramp, the respective cylinder head is in its most forward position, that is to say in its position, this firing where it closes the cartridge chamber 2.
  • the follower When the follower is in part 10 of the ramp, the cylinder head is in its most remote position relative to the cartridge chamber, that is to say, as will be seen below, in its position power supply.
  • FIG. 2 represents the supply member 13, mounted rotatably about an axis 14 to drive the strip of ammunition 15 and supply these munitions, after dismantling, to the distribution members, in stars, 16G and 16D.
  • Each of the stars 16G and 16D is a three-pointed star rotating around a respective axis 17G and 17D to rotate in the direction of the arrows 18G and 18D.
  • the leading edge 19 of each of the branches relative to the direction of rotation of the distribution stars has a circular section of substantially the same radius as the ammunition 15 in order to drive the latter during the rotation of the star.
  • the trailing edge 20 forms a guide profile which is connected, when the distribution star is stopped, with a guide profile 21 of the supply conduit 22, and a guide profile 23 of a fixed part 24.
  • FIG. 2 also shows the left cylinder head 6G mounted on the cylinder head 7G, of which the follower member 8G is integral engaged in the control ramp of the rotary drum 4.
  • the cylinder head In order to guide the cylinder head, it is mounted on 25G fixed rails.
  • the right cylinder head is not shown but it can nevertheless be seen that it is guided by rails 25D in a plane symmetrical to the plane of the cylinder head 6 with respect to the axis 26 of rotation of the drum 4.
  • the following follower members of the two cylinder heads are arranged at 180 ° from one another in the ramp 5.
  • Figure 2 also shows the locks 27 of safety in the event of a long fire. These locks will not be described in more detail, being already known in themselves.
  • Figure 2 shows the ejection channels 28 for the casings of the munitions which have just been fired. These sockets are brought to the level of these channels by being pushed by the leading edge 19 of the respective feed star and by being guided by slides 29.
  • the sockets are then ejected through the channels 28 using the pushers 30 integral with each of the cylinder heads 6.
  • This figure shows the axis 26 of the drum 4 which, as described above, is driven using an external motor 3.
  • a pinion 31 is mounted on the axis 26 and meshes with a pinion 32 mounted on a shaft 33, on which is mounted a second pinion 34.
  • the pinion 34 meshes with a pinion 35 mounted on a shaft 36, on which is also mounted the double cam 37 of a Fergusson system of known type.
  • This double cam 37 cooperates with 2 cages 38G and 38D each provided in a known manner with six fingers 39 meshing with the projections 40 of the double cam 37.
  • each cage 38 performs a third of a turn during the passage of the projections 40.
  • the cage 38D is mounted on the axis 17D of the supply star 16D while the cage 38G is mounted on a shaft 41 arranged angularly with respect to the shafts 36 and 17D so as to synchronize the rotations of the distribution stars 16G and 16D.
  • the shaft 41 also carries a pinion 42 in. grenant with a pinion 43 mounted on the shaft 17G of the distribution star 16G.
  • a pinion 44 is mounted on the shaft 14 of the feed member 13 and meshes with the pinion 35 so that this feed member 13 is driven in a continuous rotational movement.
  • the arrows in FIG. 3 represent the directions of rotation of the different shafts, the continuous arrows representing a continuous movement and the discontinuous arrows indicating a discontinuous movement.
  • the pinions 31 and 34 have the same number of teeth; likewise the pinions 32 and 35 on the one hand, and the pinions 42 and 43 on the other. Finally, the angle a between the axes 17D and 41 relative to the axis 36 is 135 °.
  • the intermittent movements of the two stars 16G and 16D are suitably synchronized and take place in the opposite direction.
  • FIGS 5a to 5i show the different stages of operation of the supply device.
  • the distribution stars 16G and 16D are stationary, only the feed member 13 rotating around the axis 14 while simultaneously driving 2 munitions 50 and 51.
  • the ammunition 50 is dismantled, while the ammunition 51 is brought between the stars 16G and 16D. It is also during this period that a munition 52 is fired in the right tube.
  • Figures 5d to 5f show the rotation of the right distribution star 16D. During this rotation, the left distribution star 16G remains stationary. The feed member 13 of course continues to rotate, but, since the rotation of the star 16D is very rapid, the movement of the member 13 is not apparent in FIGS. 5d to 5f.
  • FIG. 5d It can be seen in FIG. 5d that the ammunition 51 is driven by one of the leading edges 19 of the star 16D while being guided by one of the trailing edges 20 of the star 16G. The movement continues in FIG. 5e where the ammunition 51 is then guided by the profile 23 of the member 24.
  • the ammunition 52 is pushed between the guides 29 by one of the edges of the star 16D to its ejection position in FIG. 5e.
  • the supply member 13 continuing to rotate, we return to the steps of FIGS. 5a to 5c described above in which the ammunition 50 is brought between the stars 16G and 16D, and an ammunition 53 is fired in the left tube.
  • the left distribution star 16G then sets in motion as shown in FIGS. 5g to 5i, the distribution star 16D remaining stationary.
  • FIGS. 5 g to 5i are similar to those of FIGS. 5 d to 5f, the ammunition 50 being brought to the left breech and the ammunition 53 being brought into the ejection position.
  • FIG. 4 A certain number of points of the ramp 5 are indicated in FIG. 4. Near each of these points, it is indicated in which FIG. 6 the right (G) and left (D) cylinder heads are at this point. For example, the left cylinder head passes at the point referenced 60 in Figure 6e and the right cylinder head passes at this same point 60 in Figure 6b.
  • FIG. 6a represents the right breech stopped in the rear feeding position, that is to say with its follower member in part 10 of the control ramp 5.
  • the left breech begins to move back with its member follower at the start of part 11 of the ramp.
  • the right bolt then stops in the forward position, while the left bolt begins to move forward ( Figure 6e).
  • the ammunition in the right cartridge chamber is ignited during this phase.
  • the right breech then moves backwards (figure 6f) and continues this movement - (figure 6g) while the left breech continues to move forward.
  • FIG. 6 i is identical to FIG. 6a, the right and left cylinder heads having returned to their starting position.
