Definitions

  • the invention relates to a device for supplying cartridges, primarily two different types of ammunition, to a Gatling gun according to the preamble of claim 1.
  • a device of this type hereinafter also referred to as a double feed, is a device with which two different types of ammunition can optionally be fed to a Gatling cannon. This enables the ammunition type to be switched between the bursts.
  • Double feeders of this type are known, for example, from DE 3 040 798 C2, two endless transport devices with which ammunition is fed being arranged displaceably with respect to a third device.
  • both endless transport devices are mechanically displaced, with a gear wheel of one of the endless transport devices being in engagement with a gear wheel of the third device.
  • either one or the other endless transport device is optionally also driven in this solution and thus one or the other type of ammunition is fed to the Gatling cannon.
  • Empty pods remain after repositioning after a burst of fire with the one type of ammunition both in the Gatling cannon and in the third device. The remaining empty casings in the Gatling cannon and in the third device reach the other endless transport device in the next round of fire with the other type of ammunition.
  • repositioning means the reverse running of the Gatling cannon, third device and endless transport device in order to create readiness for fire again.
  • cartridges are conveyed in the opposite direction by Gatling cannon, third device and endless transport device, but not fired.
  • the invention solves the problem of simplifying the device for feeding cartridges of two different types of ammunition to a Gatling gun and when repositioning the transport of empty sleeves through the third device and through the Gatling gun avoid.
  • the advantage of the present invention is that the transport devices no longer have to be moved when changing ammunition, namely when coupling with the third device and the Gatling cannon. This simplifies the construction in the area of the third facility.
  • a preferred embodiment of the invention uses as a coupling device for coupling one or the other transport device with the third device and the Gatling cannon couplings which are actuated via shift levers. This makes it possible to shoot without switching pauses when using only one type of ammunition from both magazines.
  • a device for feeding cartridges 5 or 6 of ammunition types A or B which is also referred to as a double feed, is assigned to a Gatling cannon 1, which contains a number of breeches 2.
  • the double feed has a first transport device 3 and a second transport device 4 for transporting cartridges 5 of ammunition type A and cartridges 6 of ammunition type B.
  • the cartridges 5 or 6 of ammunition type A or B are conveyed from magazines, not shown.
  • a third device 8 is provided, which is used for receiving and feeding cartridges 5 or 6 of ammunition type A or B to the closures 2.
  • a drive source 7 with which the Gatling cannon 1, the third device 8 and, optionally via a coupling device 9, the first or the second transport device 3 or 4 can be driven.
  • storage devices 10 are provided which serve to receive empty cases 11 or 12 of ammunition type A or B from the first or second transport device 3 or 4 during repositioning. These storage devices 10 ensure that both the Gatling cannon 1 and the third device 8 are free of empty sleeves 11 or 12 before a new burst of fire.
  • FIG. 2 shows part of the double feed assuming that cartridges 5 of ammunition type A are fired.
  • Cartridges 5 of ammunition type A are fed to the first transport device 3 via a cup chain 13 and to the third device 8 via a transport wheel 20.
  • the cartridges 5 are transferred to a central deflection wheel 24 and passed on with the aid of deflection wheels 22, 23, 25 to the locks 2 of the Gatling cannon 1.
  • the empty sleeves 11 are returned by the Gatling cannon 1 to the third device 8.
  • the empty sleeves 11 are returned to the first transport device 3 via the transport wheel 20 and the cup chain 13.
  • the drive source 7 is connected to the Gatling cannon 1 and the third device 8 via a gear (not shown) and to the coupling device 9 via a further gear 42, with which either the first and / or the second endless transport device 3 or 4 can be coupled.
  • cartridges 5 or 6 of ammunition type A or B are optionally fed to Gatling cannon 1.
  • the coupling device 9 contains clutches 40 and levers 41 for actuating the clutches 40. According to the above description, the first transport device 3 is coupled here.
  • FIG. 3 shows one of the storage devices 10 as they belong to both the first and the second transport devices 3 and 4 according to the previous explanations.
  • the following explanations are made here for the first transport device 3, but also apply mutatis mutandis to the second transport device 4.
  • the storage device 10 is shown here in the position as it was before the firing of a renewed round of fire with cartridges 5 of ammunition type A, or after the firing Repositioning occurs. To explain the process, reference is made to FIGS. 4a to 4d.
  • the storage device 10 is also a transport device with a cup chain 50 which rotates on transport wheels 51.
  • the drive of the storage device 10 is not shown here, but can be done in one of the ways known to the person skilled in the art.
  • the storage device 10 is arranged such that it can take over empty sleeves 11 from the first transport device 3 when repositioning via a transfer star wheel 52.
  • This transfer of empty sleeves 11 into the storage device 10 takes place only during the repositioning and is controlled by a sensor 54 and a changeover switch 53.
  • the empty sleeves 11 are then pushed back out of the storage device 10 and transferred via the transfer star wheel 52 to the first transport device 3, which in turn transfers them back into an ammunition magazine (not shown) transported.
  • sensors which can determine when a repositioning process has ended, namely precisely when the foremost cartridge 5 has again reached the position according to FIG. 4a.
  • 4a, 4b, 4c, 4d now shows the different phases of the function of the double feed according to the invention in the case of a burst of fire with cartridges 5 of ammunition type A.
  • the following explanations apply mutatis mutandis to bursts of fire with cartridges 6 of ammunition type B, which is why the corresponding phases are no longer shown are.
  • FIG 4a the situation is shown schematically, which is to be referred to as the fire readiness position. It occurs when the repositioning process is finished.
  • the first transport device 3 On the first transport device 3 there are cartridges 5 of ammunition type A.
  • the foremost cartridge 5, that is to say the one which is fired first in the subsequent burst of fire, is already on the transport wheel 20. In this position, the repositioning process was stopped after the last burst of fire.
  • FIG. 4b schematically shows the situation that occurs shortly after the start of a round of fire with cartridges 5 of type A ammunition.
  • Cartridges 5 of ammunition type A are conveyed from the first transport device 3 to the third device 8, which in turn transfers them to the Gatling cannon 1.
  • the cartridges 5 are fired continuously and the empty sleeves 11 are brought back by the Gatling cannon 1 and the third device 8 to the first transport device 3, which in turn transports them back into the ammunition magazine, not shown.
  • the storage device 10 With the beginning of the forward movement of the first transport device 3, the third device 8 and the Gatling cannon 1, the storage device 10 has also started to move, and the empty sleeves 11 which have been temporarily stored on it from the last repositioning process via the transfer starwheel 52 to the return the first transport device 3. Since just as many empty sleeves 11 were temporarily stored in the storage device 10 during the last repositioning process as would have been possible on the retraction path, there will ultimately no longer be a gap on the first transport device 3.
  • FIG. 4c schematically shows the situation that occurs after the end of the firing with cartridges 5 of ammunition type A and after the system has been shut down for a period of time.
  • the devices 3, 8, 1, 10 do not stop immediately, but are braked within a certain time.
  • cartridges 5 of ammunition type A that have not been fired are transported further through the Gatling cannon 1 and are returned to the first transport device 3. They are transported further on the transport device 3 to a point which lies directly in front of the transfer star wheel 52 of the storage device 10.
  • the run-out process is therefore stopped exactly when the sensor 54 detects the first cartridge 5 that has not been fired.
  • the switch gate 53 of the memory device 10 is switched over when the system is at a standstill.
  • FIG. 4d schematically shows the situation as it occurs shortly after the repositioning process begins.
  • the switchover point of the storage device 10 was switched over so that it redirects empty sleeves 11 to the storage device 10 during the repositioning process.
  • the first transport device 3, the third device 8, the Gatling cannon 1 and the storage device 10 are set in motion in the opposite direction.
  • the cartridges 5 are transported back in the direction of the ammunition magazine, not shown.
  • the empty pods 11 of ammunition type A are therefore no longer transported back by the Gatling cannon and the third device 8, but are instead redirected to the storage device 10.
  • the repositioning process is ended when the Gatling cannon and the third device 8 are free of cartridges 5 of ammunition type A that have not been fired. This is the case when the position according to FIG. 4a is reached again. This final position or readiness for fire is detected by a further sensor which has already been mentioned but not shown. Thereupon the changeover switch 53 is also switched back to the original position.
  • Figure 5 shows a schematic representation of the function of the double feed according to the invention when shooting with only one type of ammunition from two magazines. It is also assumed here that cartridges 5 of ammunition type A are used for shooting. In this example, too, the magazines from which the cartridges 5 are conveyed are not shown. The advantage of such an operating mode is that cartridges can be fired from both magazines without changing the magazine.
  • the ammunition magazines, not shown, the two transport devices 3 and 4, the third device 8 and the Gatling cannon 1 are interconnected to form an ammunition loop.
  • Cartridges 5 are thus initially transported from one ammunition magazine (not shown) from the first transport device 3 via third device 8 and second transport device 4 to the other ammunition magazine (not shown). Since both ammunition magazines are in themselves endless transport devices, one ammunition magazine replaces the consumption of the other ammunition magazine for the time being.
  • Cartridges 5 thus get back to the second transport device 4 and are transported from there via third device 8 to the Gatling cannon 1 and fired there. Empty sleeves 11 are then again conveyed via third device 8 onto the first transport device 3, and from there back into the ammunition magazine.
  • the storage device 10 prevents empty sleeves 11 from being transported through the Gatling cannon 1 and through the third device 8 during repositioning. Thus, it is also ensured here that the first shot of a burst of fire occurs only after the Gatling cannon 1 has run up and that ultimately only empty sleeves 11 reach the ammunition magazines (not shown).
  • guide devices 27 are necessary which correctly guide the cartridges 5, 6 and the empty sleeves 11, 12 in the third device. These guide devices 27 and their corresponding positions are shown in more detail in FIGS. 6-8.
  • FIG. 6 shows schematically the ammunition guidance and the position of the guide devices 27 when firing with cartridges 5 of ammunition type A.
  • the directions of rotation of the deflection wheels 22, 23, 25, 26 and of the central deflection wheel 24 can also be seen from this figure.
  • Figure 7 shows schematically the ammunition guidance and the position of the guide devices 27 when firing with cartridges 6 of ammunition type B. From this figure it can be seen that the directions of rotation of the deflection wheels 22, 23, 25, 26 and of the central deflection wheel 24 are the same as when firing with cartridges 5 of ammunition type A.
  • the guide devices 27 are connected to one another by mechanical control elements (not shown) such that the first transported cartridge 5 of ammunition type A can automatically steer the guide devices 27 into the position according to FIG. 6. Likewise, the first transported cartridge 6 of ammunition type B can automatically steer the guide devices 27 into the position according to FIG. 7. This mechanical self-control can always be used when cartridges 5,6 of two different types of ammunition are fired.
  • FIG. 8 shows schematically the ammunition guidance and the position of the guide devices 27 when firing with cartridges 5 of ammunition type A from two magazines. It can also be seen from this figure that the directions of rotation of the deflection wheels 22, 23, 25, 26, of the central deflection wheel 24 and of the transport wheels 20, 21 are the same as when firing with cartridges 5 or 6 of ammunition type A or B.
  • the storage devices 10 are provided as endless transport devices.
  • Other embodiments are conceivable, such as sliding magazines such as those used in other automatic weapons, for example in rapid-fire rifles.
