Definitions

  • the invention relates to a safety device on a third-party gun, with a weapon barrel and an inevitably moving back and forth breech which can be locked in its foremost position.
  • the invention relates to a safety device on a multi-barrel gun that is mounted on a cradle that can move backwards, that moves from a front position to a rear position through the recoil and that has a weapon housing with a rotor rotating therein, on which a tube bundle is arranged is, with a lock for each gun barrel, which can be locked with the gun barrel before firing a shot.
  • a device of this type is known (see DE-A 1 809699) for interrupting the series fire of an automatic rapid-fire weapon of the Gatling type in the event that a cartridge or a cartridge case has not been pulled out of the cartridge chamber of the weapon barrel.
  • means are present which prevent bullets from being fed to the cartridge chamber of the weapon barrel if there is still a cartridge which has not been pulled out after rotation of the weapon barrel bundle.
  • These means contain a scanning element which prevents the advance of the closure when the cartridge that is not pulled out is touched.
  • there is a switch which prevents the closure from being advanced in a first position and enables the closure to be advanced in a second position, the crossover being coupled to the scanning device.
  • This known device has the disadvantage that premature unlocking of the breech cannot be prevented when a cartridge is delayed. There is therefore a risk that, in the event of a delay in ignition, the propellant charge of the cartridge is ignited after the lock has been unlocked. If a cartridge is still ignited after the breech has been unlocked, this can result in the destruction of essential parts of the weapon. The operator of the weapon is also at risk.
  • the object that is to be achieved with the present invention is to provide a safety device that reliably prevents the propellant charge of a cartridge from being ignited after the lock has been unlocked in the event of an ignition delay.
  • a multi-barrel gun like a "Gatling cannon” has a tube bundle that is attached to a rotor that rotates in a weapon housing around the central axis of the tube bundle.
  • This rotor contains guide tracks arranged in the longitudinal direction of the weapon, for the closures assigned to the tubes of the bundle.
  • the cartridges are first inserted into the gun barrels through the forward and reverse movement of the breeches on these guideways. After the cartridges have been fired, the empty cartridges are pulled out of the gun barrels and ejected while the rotor rotates about its axis.
  • a cam roller is provided on each breech which engages with an elliptical cam track on the weapon housing in which the rotor is mounted.
  • a cartridge conveying device for feeding cartridges from a magazine into the aforementioned weapon housing, in which they are gripped by the breeches. Due to the elliptical curved path, the shutter is inevitably moved back and forth.
  • the safety device is characterized in that the breech has a breech block and a breech head which are coupled to one another and that a device for disengaging the breech block from the breech block locked with the weapon barrel is present, which responds to the delay in ignition of a cartridge .
  • This device can e.g. respond if there is no propellant gas pressure.
  • the said device is then connected to this gas piston, which prevents unlocking of the closure if the gas piston remains in its working position in the event of an ignition delay.
  • This device can e.g. even in the absence of the weapon barrel recoil by the force generated by the propellant gases, the device responding either to the return or to the subsequent advance of the weapon relative to the stationary cradle.
  • a cam plate is attached to the weapon housing and an inertial mass is slidably arranged on the breech, which can be moved from an active position into an ineffective position relative to the weapon by the recoil of the firearm in order to prevent unlocking of the breech, in the event of a delay in ignition the inertial mass remains in its active position.
  • a cam plate is attached to the cradle which engages an actuator when the gun is in its forward position to prevent the breech from unlocking if the gun moves forward from its rearward position upon ignition delay emotional.
  • this device can also be used in the absence of gas pressure in the cartridge case speak to.
  • this case there is a recess in a chamber of the weapon barrel, which serves to receive the cartridge, into which the cartridge case is bulged out by the gas pressure.
  • a stylus protrudes into this recess and can be moved from a working position to a rest position.
  • An actuating device is connected to the stylus in order to prevent unlocking of the closure if the stylus remains in its working position in the event of an ignition delay.
  • a gas extraction channel in the weapon barrel for moving a gas piston by the gas pressure from a working position into a rest position and an actuating device is connected to the gas piston to prevent unlocking of the breech if the gas piston is in its working position remains.
  • a Gatling cannon has a tube bundle 10 with six weapon tubes 11, which are fastened with their rear end in a rotor 12.
  • the tube bundle 10 is rotatably supported at the front in a carrier 13.
  • the rotor 12 is also rotatably mounted in a weapon housing 14.
  • a ring gear 15 fastened to the rotor 12 is in engagement with a gear 16.
  • Five gears 17-21 of this gear 16 are visible in FIG. With an electric motor, not shown, the rotor 12 is driven with a tube bundle 10 via this gear 16.
  • the weapon housing 14 is attached to a return device 22, which essentially consists of two plate spring assemblies 23 and 24.
  • an ammunition supply housing 26 is fastened to the weapon housing 14, to which the cartridges 25 are fed on an endless conveyor belt 27 in the direction of arrow A, the empty conveyor belt 27 moves in the direction of arrow B to an ammunition container (not shown).
  • the empty cartridge cases 28 are ejected from the housing 26 in the direction of arrow C.
  • the rotor 12 rotatably mounted in the weapon housing 14 has guide rails 29.
  • a closure 30 is slidably mounted between two guide rails 29.
  • a cam roller 31 is attached to each closure 30 and engages in a closure control curve 32.
  • This breech control curve 32 is located in the weapon housing 14 and has the effect that the breech 30 is pushed back and forth once when the rotor 12 is rotated fully in the weapon housing 14.
  • a cartridge 25 is inserted into the weapon barrel 11 when the breech 30 is advanced and when it is returned slide the breech 30, the empty cartridge case 28 is pulled out of the gun barrel 11 and ejected.
  • the foremost position of the breech 30 it is locked before the shot is fired.
  • the breech 30 is unlocked again. Since, as mentioned, the rotor 12 is driven by an electric motor, the closure 30 is advanced, locked, unlocked and withdrawn.
  • a device is present which prevents the closure 30 from being unlocked prematurely in the event of an ignition delay. This device is described below.
  • the closure 30 has a closure carrier 33 and a closure head 34 which, as can be seen in FIG. 4, can be separated from one another.
  • this separation of the closure head 34 and the closure carrier 33 takes place only in the case of the ignition delay mentioned above.
  • the locking head 34 has ten locking cams 35, which, however, are only partially visible in FIG. 3. By turning the locking head 34, these locking cams 35 are placed in the rotor 12.
  • a locking body 62 is slidably mounted in the closure head 34. This locking body 62 has steep, helical ribs. As soon as the closure head 34 has reached its foremost position when the closure 30 is advanced, the locking body 62 shifts from the position shown in FIG. 3 to the position shown in FIG. Since the locking body 62 is secured against rotation thanks to its attachment in a locking head holder 64, the locking head 34 is rotated by the helical ribs 63 during this displacement and thereby locked in the rotor 12 in a bayonet-like manner. This locking can also be seen in FIG. 6.
  • the weapon barrel 11 fastened in the rotor 12 has a loading chamber 36 for receiving a cartridge.
  • a gas extraction opening 37 At the front end of this chamber 36, near the mouth of a cartridge case 28, there is a gas extraction opening 37.
  • This gas removal opening 37 is connected to a gas channel 39 via a deflection nozzle 38.
  • the gas channel 39 opens into a gas chamber 40 in which a piston 41 is slidably mounted.
  • a spring 42 which is supported on the bottom of the gas chamber 40 and tends to push the piston 41 forward, i.e. to move to the left in Fig.
  • the piston 41 has a cam 43 which serves to actuate a lever 44.
  • This two-armed lever 44 is pivotally mounted about an axis 45 in the weapon housing 14 and is supported with its one arm 46 on the cam 43 of the piston 41 and with its other arm 47 on a second two-armed lever 48.
  • This second two-armed lever 48 (see also FIG. 7) is pivotally mounted about an axis 49 in the weapon housing 14 and is supported with its one arm 50 on the arm 47 of the first two-armed arm Lever 44 and with its second arm 51 on a third two-armed lever 52.
  • This third two-armed lever 52 is mounted about an axis 53 in the weapon housing 14 and is supported with its one arm 54 on the arm 51 of the second two-armed lever 48 from time to time his other arm 55 on an actuating lever 56 which is rotatably mounted about an axis 57 in the locking head 34. With this actuating lever 56, the closure head 34 can be separated from the closure carrier 33, as described below.
  • a first spring 58 is arranged in the weapon housing 14, which is supported on the arm 50 of the second lever 48 via a sleeve 59. Furthermore, a second spring 60 is arranged in the weapon housing 14, which is supported on the arm 51 of the second lever 48 via a sleeve 61 and via the arm 54 of the third lever.
  • These two springs 58 and 60 have the tendency according to FIG. 7 to pivot the second lever 48 counterclockwise and according to FIG.
  • the first lever 44 also counterclockwise, but to pivot the third lever 52 clockwise.
  • an ignition pin 65 is slidably mounted in the closure carrier 33.
  • a spring 66 which is supported on the one hand at the rear end of the firing pin and on the other hand on the closure carrier 33, tends to push the firing pin against the bottom of the cartridge case 28.
  • a driver 67 is also attached, which cooperates with a cam, not shown, to release the firing pin 65 at the desired moment for piercing the cartridge 25.
  • the locking head 34 and the locking head holder 64 are coupled to the locking carrier 34 by two bolts 68 and 69.
  • Bolts 70 are fastened to these bolts 68 and 69 and are rotatably mounted in the locking head holder 64.

  • Each closure 114 is slidably supported in the rotor 110 in longitudinal guides 115. 22 shows two locks 114, of which one lock 114 is in its foremost, locked position and the other lock 114 is in its rearmost, unlocked position.
  • Each closure 114 has a closure head 116 and a closure head holder 117.
  • Closure head 116 and closure head holder 117 together form a known twist lock, ie the The closure head 116 is connected to the closure head holder 117 via a steep screw thread 118. Cams 119 of the closure head 116 engage in recesses 120 in the rotor 110 when the closure 114 is locked in its foremost position.
  • the breech 114 also has a spring-loaded ignition pin 121 which, in the foremost, locked position of the breech 114, can pierce a cartridge 122 located in the weapon barrel 111.
  • the breech 114 also has a cam roller 123 which engages in a first control cam 124 in the weapon housing 113.
  • this cam 124 causes the individual breeches 114 to be pushed back and forth.
  • the control curve 124 is arranged elliptically on the inside of the essentially cylindrical weapon housing 113.
  • the breech 114 remains in its foremost position when the cam roller is in motion 123 is in the control cam 125 and the breech 114 remains in its rearmost position when the cam roller 123 is in the other circular control cam 126 of the weapon housing 113.
  • Points 127 and 128 are provided so that the cam roller 123 can get from one elliptical control curve 124 into one or the other control curve 125 or 126.
  • the two switches 127 and 128 are pivotally mounted about axes 129.
  • the cam roller 123 moves in the control curve 124 in the direction of the arrow S. In the position of the switches 127 and 128 shown, the cam roller 123 thus remains in the elliptical control curve 124.
  • the organs described below are used to actuate these switches.
  • each weapon barrel 111 has a gas removal opening 130 through which propellant gas can enter a gas chamber 132 via a gas channel 131.
  • a gas piston 133 In this gas chamber 132 there is a gas piston 133, which reaches the position shown by the gas pressure.
  • the gas piston 133 has a cam 134 which interacts with a cam 135 of a locking lever 136.
  • This locking lever 136 is loaded by a spring 137, which tends to press the locking lever 136 with its cam 135 against the cam 134 of the gas piston 133.
  • the locking lever 136 is pivotally mounted about an axis 138. As can be seen from FIG. 20, the locking lever 136 engages in a recess 139 in the switch 127 in the position shown and thus prevents the switch 127 from being pivoted out of the position shown.
  • a second locking lever 140 is also pivotally mounted in the housing 113 about an axis 141.
  • the lock lever 140 has a first arm 142 that senses the presence of a cartridge 122. If a cartridge 122 strikes against this arm 142 (see FIG. 24), the locking lever 140 is pivoted about its axis 141 until a second arm 143 of the locking lever disengages from the switch 127, whereby it can be pivoted freely.
  • a second scanning lever 144 is used to monitor stuck cartridges. This sensing lever 144 is pivotally attached to a rod 145.
  • a sub-latch 146 is fastened, which in the position shown in FIG. 26 prevents the switch 128 from being pivoted. If a cartridge 122 is stuck in the weapon barrel 111, the scanning lever 144 is pivoted when the rotor 110 rotates, as a result of which the pawl 146 is also pivoted via the rod 145 and the switch 128 is released.
  • An actuating lever 147 is fastened to the ignition pin 121 and cooperates with a control cam (not shown). This control curve releases the ignition pin 121 at the right time for piercing the cartridge 122.
  • the scanning lever 144 which - as mentioned - serves to monitor stuck cartridges, is attached to the rod 145 mounted in the weapon housing 113.
  • a cam 159 is also attached to this rod 145, which engages in a fork 161 of a second idling pawl 160.
  • This idling pawl 160 is pivotally mounted in the weapon housing 113 about an axis 163 and, in addition to the fork 161 mentioned, also has an arm 162. 23, this arm 162 interacts with the cam roller 148 of the closure 114. As can be seen from FIG.
  • the switch 127 is pivoted completely by the cam roller 123 and the cam roller 123 moves from the elliptical control curve 124 into the circular control curve 125.
  • the lock 114 thus no longer moves back and remains locked in its foremost position. Since the switch 127 unlocks, i.e. is no longer held by the locking lever 136, the locks 114 of the remaining five weapon tubes 111 will also remain in their foremost, locked position during the further rotation and the weapon will no longer fire.
  • the firearm behaves differently according to the third exemplary embodiment (FIG. 23). If here the cartridge is ignited with a certain delay or not at all, no propellant gas penetrates into the chamber 132 and the piston 133 is not displaced.
  • the co-rotating gas piston 133 with its cam 134 abuts against the cam 151 of the actuating lever 150 mounted in the housing 113, as a result of which the actuating lever 150 is pivoted about the axis 138 and, via the pawl 152 supported by the blocking lever 157, the idling pawl 154 pivoted counterclockwise according to FIG. 24.
  • the arm 156 of the idle pawl 154 is pressed against the center of the rotor 110.
  • the idle pawl 154 also comes into its initial position and the locks of the remaining gun barrels 111 can continue to move back and forth.
  • the weapon would therefore be able to continue firing with only five out of six weapon tubes 111. To prevent this, the weapon is automatically stopped in the event of an ignition delay.
