  • Patent number: 6345562
    Abstract: Cartridges (5) are guided during a loading phase shortly before reaching the automatic cannon (1) onto a first track, which differs from the conveying direction of the conveyor chain (14) and are guided at a greater distance from the revolving drum (13) around the shaft (15) of the revolving drum, and conveyed on. In a firing phase, the cartridges (5) are guided shortly before reaching the automatic cannon (1) onto a second track, which differs from the conveying direction of the conveyor chain (14), are guided around the shaft (15) of the revolving drum (13), and are sequentially brought into a firing position directly behind the revolving drum. After having been fired and ejected, the empty cartridge cases (6) are caught and are transported on the first track into a magazine (4).

  • Patent number: 6339983
    Abstract: In connection with this ammunition-feeding device, an axial transport device (19) with a conveyor chain (34) is provided between a conveyor (6) and a transfer station (20) for transferring cartridges (2) to a revolver drum (25) of a revolver cannon, by means of which the cartridges (2) are displaced in their longitudinal direction during transport vertically in respect to the movement direction of the conveyor chain (34). A buffer shaft (35) is provided for driving the conveyor chain (34), wherein the drive by means of the buffer shaft (35) takes place in such a way that, prior to being transferred to the transfer station (20), the cartridges (2) are brought into a buffer position.

  • Patent number: 5076138
    Abstract: When cartridges are delivered from a stationary cartridge magazine to an elevatable firing weapon, it is customary to use a deflection or guidance unit, by which the cartridges can be reliably delivered to the elevatable firing weapon in every position of the latter. The cartridges are delivered to the elevatable firing weapon in a telescopic guide or infeed channel. With large elevation of the elevatable firing weapon, this telescopic guide channel is substantially contracted. On the other hand, this telescopic guide channel is substantially extended when the elevation of the elevatable firing weapon is relatively small. In the telescopic guide channel there is provided a bucket chain for conveying cartridges. The individual buckets of this bucket chain are interconnected by knee joints, so that the bucket chain can likewise be extended and contracted. One end of the telescopic guide channel is mounted at the stationary cartridge magazine and the other end is mounted at the elevatable firing weapon.

  • Patent number: 4890537
    Abstract: In a firing weapon with an elevatable weapon barrel, it must be possible to fix or lock the weapon barrel in each desired position. For this purpose, known firing weapons are equipped with braking devices in which large frictional forces occur, thereby making it necessary to use servo-mechanisms. In accordance with the invention, the elevation of the weapon barrel is fixed or locked by means of a cylinder and a piston. The piston comprises a closeable through-passage opening through which a pressure medium flows, as long as the through-passage opening is open between a chamber located on one side or face of the piston into an other chamber located on the other side or face of the piston. The through-passage opening is closeable for fixing or locking the weapon barrel at a predeterminate elevation.

  • Patent number: 4742756
    Abstract: During the infeed of cartridges into a firing weapon cartridges are withdrawn from the sectors of a drum magazine using a first conveyor, and subsequently transferred to a second conveyor which conveys the cartridges to the firing weapon. A return or reverse movement blocking device prevents the cartridges from dropping back into already emptied sectors of the drum magazine. Such return or reverse movement blocking device possesses two pivotable flaps or vane members which may be interconnected and conjointly form a funnel-shaped channel through which the cartridges are displaced by the first conveyor from the drum magazine to the second conveyor.

  • Patent number: 4397214
    Abstract: An apparatus for the lubrication of the locking bolts of a breechblock of an automatic firing weapon enables, with very little maintenance, reliable lubrication of the locking bolts. The lubrication apparatus contains a hydraulically loaded supply container, a hydraulically actuatable dosing device, and a hydraulically releaseable or unlockable check or non-return valve, in order to spray or otherwise apply a lubricant by means of spray or injection nozzles upon the locking bolts within a breechblock housing.

  • Patent number: 4388826
    Abstract: A weapon simulator for checking the removal of ammunition from a magazine at the rhythm or cadence with which the firing weapon is fired comprises two cams for feeding the cartridges and mounted upon a shaft driven by a drive motor. The shape of the cams is such that during the removal of the cartridges there occur the same accelerations and decelerations as during the removal of cartridges by means of a firing weapon during series firing.
