Definitions

the invention relates to a device for inserting a cartridge into the cartridge chamber of the weapon barrel of an automatic firearm, with a reciprocating breech which pushes the cartridge from a cartridge feed channel arranged next to the weapon barrel into the weapon barrel and with guides which guide the cartridge located in the cartridge feed channel distract against the gun barrel.
the present invention aims to provide a simple, reliable device which does not require additional actuators.
the device according to the invention is characterized in that the said guides are formed by a deflection pawl which is arranged in the area of the cartridge tip of the cartridge located in the cartridge feed channel, that the deflection pawl is pivotably mounted so that its pivot axis is parallel to the Cartridge axis is directed that the deflecting pawl protrudes into the cartridge feed channel that it can be swung out of the cartridge and forms a backstop, which prevents the cartridge tip from inadvertently sliding back into the cartridge feed channel.
the said guides are formed by a deflection pawl which is arranged in the area of the cartridge tip of the cartridge located in the cartridge feed channel, that the deflection pawl is pivotably mounted so that its pivot axis is parallel to the Cartridge axis is directed that the deflecting pawl protrudes into the cartridge feed channel that it can be swung out of the cartridge and forms a backstop, which prevents the cartridge tip from inadvertently sliding back into the cartridge feed channel
Fig.l a part of the gun housing 10 of a firearm is shown, to which a gun barrel 11 is attached at the front.
Two cartridge feed channels 12 and 13 are pivotally attached to the barrel 14 on the weapon housing 10.
the left cartridge feed channel 12 is shown pivoted out, so that no cartridges can be fed from this channel 12 to the weapon.
the right cartridge feed channel 13, on the other hand, is in the working position, so that the cartridges 23 can be inserted into the gun barrel 11 from this channel 13.
the pivoted-out position of the cartridge feed channel 13 is indicated by dash-dotted lines.
a switching device not shown, ensures that one or the other cartridge feed channel (12, 13) is always in the working position while the other is pivoted out.
a lock 15 is slidably mounted in the weapon housing 10.
This closure 15 is shown in its rearmost position in FIG. 1, it has a closure head 16 and a control piece 17, as well as two bolts 18.
the control piece 17 is displaceably arranged in the closure head 16. In the foremost position of the closure head 15, the control piece 17 projects between the two bolts 18 and presses the latches 18 into recesses 19 of the weapon barrel 11, so that the locking head 16 is locked in the weapon barrel 11. In the rearmost position of the lock 15, the control piece 17 is behind the bolts 18 and thus the lock head is unlocked.
the closure 15 is displaced in the usual way in one direction by a not shown spring and in the other direction by the gas pressure.
the cartridge belts are also conveyed in the cartridge feed channels 12 and 13 in the usual way. Neither is therefore described further here.
the above-mentioned feed channels 12 and 13 each have a side wall 34.
the cartridges 23 move along these side walls 34 in the feed channels 12, 13 against the gun barrel 11 in the direction of the arrows A.
the two deflection devices 24 on the right and left of the gun barrel 11 have the task of guiding the tip of the cartridges 23 against the gun barrel 11, as can be seen in particular from FIG.
each deflection device 24 which are mirror images, each have a housing 38 in which each a deflection pawl 39 is pivotally mounted about an axis 40.
a sleeve 42 which contains a spring 43 which is supported on the one hand on the bottom of the sleeve 42 and on the other hand on the bottom of the bore 41 and has the endeavor to press the sleeve 42 against the deflection pawl 39 and to keep this deflection pawl 39 in the position shown.
the deflection pawl 39 has a swivel surface 44 and a support surface 45.
the deflection device 24 ensures that the cartridge tip does not touch anywhere, but rather is pushed exactly into the cartridge chamber of the weapon barrel 11.
