Definitions

  • the invention relates to a safety device on a third-party gun, with a gun barrel, with a forcibly moving back and forth breech, which is locked in its forward position with the gun barrel, which has a breech carrier and a breech head, which are coupled together and with a Device for disengaging the breech carrier from the breech head locked with the weapon barrel, which responds to a delay in ignition of a cartridge.
  • the coupling between the closure head and the closure carrier has two latches which can be placed under a support bracket.
  • the device for disengaging the breech carrier from the breech head has a two-armed actuating lever which engages with an actuating device mounted in the weapon housing.

  • the device for decoupling the closure carrier from the closure head has a scanning device for determining whether a cartridge has been fed at all.
  • the safety device with which this object is achieved is characterized in that when the breech head is locked in the weapon barrel, the breech carrier is automatically decoupled from the breech head and that the device responding to an ignition delay is an unlocking of the breech head in the weapon barrel and a coupling of the breech carrier with the breech head prevented.

  • the sleeve 63 according to FIGS.
  • This rotation lock is designed as follows:
  • segment-shaped recesses 72 are provided in the outer cams 69, see FIGS. 10 and 12. Each of these recesses 72 serves to receive a roller 73. These rollers 73 are located in rectangular recesses 74 in the housing 75 of the closure head 51, see also FIG. 19. So that these rollers 73 cannot fall out of the recesses 74 of the housing 75, on the one hand an outer switching ring 76 and on the other hand an inner retaining ring 77 is rotatably mounted on the housing 75.
  • the outer switching ring 76 has a spur toothing 78 which engages in a corresponding counter toothing on a ring 79 which is rigidly attached to the housing 75.

  • Both the spur toothing 78 on the switching ring 76 and the spur toothing on the retaining ring 77 are designed in such a way that the two rings 76 and 77 can be rotated against the force of the plate springs 80 and 86, but are secured by these springs 80 and 86 against unintentional rotation are. 7, the rollers 73 protrude into the recesses 72 (FIG.

  • the closure head 34 has a rear roller 40, which together with a first control cam 89 acts to lock the bolt head in the gun barrel 11.
  • the breech head 34 has a front roller 39 which interacts with a second movable control cam 90 in order to unlock the breech head 34 in the weapon barrel 11. Since the locking head 34 has to be locked in the weapon barrel 11 each time, the first control cam 89 can be arranged in a fixed position. However, since unlocking may only take place if no ignition delay has occurred, the second control cam 90 must be arranged to be movable.
  • the second cam 90 is arranged on a slidable plate 91.
  • This plate 91 can be moved from its active position according to FIG. 13 into its inactive position according to FIG. 14.
  • the plate 91 has two cams 92 and 93, which are each guided in a separate guide groove 94 and 95.
  • These guide grooves 94, 95 consist of two arcuate sections 97, which are arranged concentrically to the movement path 96 of the closure 33, 34, and a straight section 98, which connects the two arcuate sections 97 to one another.
  • a pivotable lever 99 is articulated on the plate 91, which is supported on a fixed nose 100 in the active position of the plate 91 and prevents displacement of the plate 91.
  • a spring 101 tends to push the plate 91 out of its active position according to FIG. 13 into its inactive position according to FIG. 14.
  • Another spring 102 tends to pivot lever 99 clockwise via a plunger 103.
  • an angle lever 104 which is pivotably mounted about an axis 105. In the event of a delay in ignition, this angle lever 104 can be pivoted from the position according to FIG. 13 into the position according to FIG. 14 by means not shown, as a result of which the lever 99 is also pivoted against the force of the spring 102 and out of engagement with the nose 100 so that the spring 101 is able to move the plate 91 from the position shown in FIG. 13 to the left into the position shown in FIG. 14.
  • a pawl 106 is articulated on the lever 99, which can be displaced in the guide groove of the plate 91 in the direction of the arrow E, but cannot be pivoted.
  • the lever 99 is disengaged from the nose 100 by the angle lever 104, the pawl 106 engages with a cam 107 of the locking head 34.
  • This cam 107 is therefore able to push the plate 91 completely into the position according to FIG. 14, the pawl 106 again coming out of engagement with the cam 107 as soon as the spring 102 pivots the lever 99 over the plunger 103 and thereby also pushes the pawl 106 away from the cam 107.
  • Another pawl 108 serves to hold the plate 91 in its end position according to FIG. 14. This pawl 108 can snap into a hook 109 of the plate 91.
  • a pin 110 is used to release the pawl 108 from the hook 109 and to push the plate 91 back into its starting position according to FIG. 13.
  • the angle lever 104 shown in FIGS. 13 and 14 should only be actuated if a cartridge does not ignite in time, ie in the case of so-called late bloomers or "hang fire". If ignition is timely, actuation of a gas piston prevents the angle lever 104 from being actuated. If, however, no cartridge has been supplied, the gas piston cannot be actuated and nevertheless the lever 104 should not be actuated either, since there is no delayed ignition. Before a shot is triggered, it must therefore be ascertained each time whether a cartridge has been supplied at all or not, because the angle lever 104 should only be operated if a cartridge has been supplied and if the gas piston has not been actuated in time.
  • the device for determining whether a cartridge has been fed or not is shown in Figs. 15-18.
  • This device has two star wheels 110 and 111, of which one star wheel is referred to as the transfer wheel 110 and the other star wheel as the scanning wheel 111.

  • a toothed belt pulley 114 is rigidly connected to the scanning wheel 111 and drives a second belt pulley 116 via a toothed belt 115.
  • This second pulley 116 is fastened together with a third pulley 117 and a cam wheel 118 on a shaft 119.
  • the third pulley 117 drives a fourth pulley 122 via a second toothed belt 120 and a deflection roller 121.
  • a second cam wheel 123 is rigidly connected to this pulley 122.
  • the scanning wheel 111 is rotated relative to the transfer wheel 110 in such a way that the gaps of the two star wheels 110 and 111 coincide.

From the It is thus clear from the above explanations that if a cartridge 124 is present, the scanning wheel 111 assumes a different position and thus, via the pulleys 114, 116, 117 and 122 and the two toothed belts 115 and 120, the two cam wheels 118 and 123 also assume a different position than if a cartridge were present 124 is missing.
  • both the transfer wheel 110 and the scanning wheel 111 rotate continuously, and thus the two cam wheels 118 and 123 are also rotated continuously, but that with a specific position of the transfer wheel 110 (which - how said - in Fig. 15 and Fig. 16 is the same), the cam wheels 118 and 123 assume a different position if a cartridge 124 is present (Fig. 15) than if there is no cartridge 124 (Fig. 16).
