Automatic or semi-automatic firearm with double ammunition feed

Priority: Luxembourg, 29 September 1966

The invention relates to automatic

or semi-automatic firearms (especially those with a caliber between 20 mm and 50 mm), which use cartridges with the help of one or the other of two devices for supplying ammunition can be supplied to the weapon are attached and supply cartridges which are generally (but not necessarily) of various types (e.g. explosive cartridges with a feeder and tank cartridges

109836/0003

the other), the expression ^w firearm with double ammunition feed "here includes the two devices for ammunition supply, one or the other of which interacts with the actual firearm. The invention relates in particular, if not exclusively, to such automatic or semi-automatic firearms those which are supplied with belted cartridges, in which case the devices for supplying ammunition are feeders.

The purpose of the invention is esp., Such

to train automatic or semi-automatic weapons so that they better than before the various requirements of the Practice correspond, especially with regard to their space requirements in the transverse direction at the point of their devices for ammunition supply and the convenience of expanding them

For this purpose, weapons of this type have two devices for supplying ammunition (in particular two feeders at weapons supplied with belted cartridges), which are offset from one another in relation to the axis of the weapon and each in such a way

cooperate with the breech of the weapon »that this the introduction of the first cartridge to be fired into the weapon effected from the relevant device for ammunition supply,

when it returns to the working position (i.e. the closed position), j each of these devices for supplying ammunition by pivoting from a booth position, in whichever the correct cartridge to be fired from the respective ammunition supply device outside the area of the breech block the weapon can move into a working position in which this first cartridge lies on the path of the breech, according to the invention the two devices for supplying ammunition

109836/0003

mounted so that the pivoting of each around an axis takes place, which is at least approximately parallel to the firing axis of the weapon.

The invention is hereinafter referred to explained on the drawing by way of example.

1 and 2 show one according to the invention Firearm from above or from the left, partly in section.

Figs. 3 and 4 show Hatred on a larger scale

certain parts of FIG. 1 in two different operating positions.

Figs. 5 and 6 show on a larger scale

the weapon of FIG. 1 from behind, specifically in the operating state or during the removal of a feeder.

FIGS. 7 and 6 show two design modifications in the same representation as FIG. 5 Weapons.

The following is the application of the invention to an automatic firearm with a range between 20 and 50 mm lying caliber, especially with a caliber of 30 mm, explained

It is well known that an automatic or a

semi-automatic firearm for combating both earth targets and air targets are currently provided with a double ammunition feed for economic and tactical reasons be·

The price of a tank shell is about two and a half times the price of an explosive shell. Therefore, if only one weapon with a single ammunition feed is available, one is forced to either use the same belt

109836/0003

to mix the different types of ammunition, which is not economical , or to use two different belts, one of which is e.g. exclusively explosive grenades and the other contains only fan grenades, with the two straps alternating depending on the target to be fought must be drafted by the shooter, which results in a great loss of time, which can be disastrous.

This error is remedied by providing such a weapon with a double ammunition feed which is formed by two feeders, one of which e.g. explosive grenades and the other tank shells receives, these feeders are designed so that each of them used immediately and one after the other for shooting can be, depending on the choice of the shooter according to the too fighting target. In this pail, one feeder can be arranged to the left of the firing axis and the other to the right of the same will.

The weapon is then used at any suitable

Way designed so that they have two devices for ammunition feed (In particular. Two feeders 1 and 2 with an ammunition supply through cartridge belts), which in relation to the Axis X-X of the weapon are offset from one another and each so with the breech 3 of the weapon cooperate that this the introduction of the first cartridge to be fired (with A for the Feeder 1 and designated with B for feeder 2) into the weapon from the relevant device for ammunition feed, when it is in the operating position (i.e. in the closed position) from the diagram in Pig. 1, 3 and 4 shown Returns to the open position. Any of these devices

109836/0003

_5- 15/8366

for ammunition supply can be done by pivoting from a booth position, in which the first cartridge to be fired in the relevant gate direction to the Kunitionszuf uhr is out of reach of the closing 5 of the weapon is in a working position pass over in which this first cartridge is on the way of the closure, so that it is captured by this and can be taken along in general, each door direction has insertion lips shown schematically at 4 and 5 in Fig. 5, on which the first cartridge A or B to be fired lies in the waiting position.

The invention aims esp., The two gate directions for ammunition supply to the weapon or theirs. To articulate the holder in such a way that the least amount of space is required, especially in the case of a weapon for equipping an armored turret, in which the space is always limited

For this purpose, the two door directions are used to

Ammunition feed, in particular the two feeders 1 and 2, attached so that each of them is pivoted about an axis YY (Fig. 2) which is at least approximately parallel to the axis XX of the weapon either around a common axis, as shown in Fig. 2, 5 and 8, or around two axes, as shown in Fig. 7 The pivot axis or axes are expediently through a hinge 6 (Fig. 2 _f 5 and 8) or hinges% »% (FIG. 7), each hinge being held together by a single pin 7 (FIGS. 2, 5 and 8) or 7a, 7b (FIG. 7), which according to the above explanations is practically parallel to the axis XX is. This Stfeb is now preferably designed so that it has a first angle with respect to the part of the hinge that is firmly connected to the weapon.

position, in which he can exercise or the feeder inevitably hold the weapon, and at least take a different angular position., in which he can hold the. Expansion of a feeder permitted by removing it across this pin.

In the one shown in Figs

The fixed part of the single hinge has the export shape of the hinge. Hinge 6 holder 8, which are firmly connected to the lock box 9 (or according to an embodiment modification not shown with the holder of the weapon) and have such a mutual distance that they can accommodate the forks 10 and 11 in pairs, which are fixed to the Feeder t and 2 are connected vtnä. form the movable cables of the hinge, the pin 7 then being inserted into the holder 8 and the cables 10, 11. The pin 7 has flattened areas 47 at the location of the sabers 10 and 11, the mutual spacing a of which is smaller than the opening To of the forks, which in turn is smaller than the diameter d of the sections of the pin 7 not provided with flattened areas. The pin has elastic perforated washers 53 (FIG. 2), which hold it in its angular position visible in FIG. 5, in which the flattened areas 47 form a certain angle with the openings of the forks 10 and 11, as well as a lever 54 (FIG. 2 and 8), by means of which the pin 7, after overcoming the resistance of the perforated discs 53 can be rotated so that it comes in the position in which the arrangements 47 in alignment with the tapes of either the G _a bel 10 (Fig. 6 ) to remove the feeder 1, or the fork 11 to remove the feeder 2 (e.g. to make it easier to transport the weapon or to store it). For this purpose, the openings of the forks 10 and 11 are offset from one another, as shown in FIGS. 5-6 and 8

109836/0003

emerges so that the two feeders cannot be expanded at the same time.

In the embodiment shown in Fig. 7, each hinge 6a and 6b has the same parts as the hinge 6 of Figs. 5, 6 and 8, which with the same Reference numerals are designated to which the letters a and b appear on the hinge 6a or 61). The only difference is that between each pair of holders 8 only a single fork 10 or 11 passes through it.

Feeders 1 and 2 have lids 12 and 13, which are carried by hinges 14 and 15 and are normally locked by hooks 16 »which are not springs shown are printed in recesses 17 formed in the body of the feeder. The hooks 16 are fixed with Levers 18 connected, by means of which they can be pulled out of their recesses 17 when the covers 12, 13 s · B. should be opened for loading and unloading the weapon. Vie In particular. Shown in Fig. 1 and 2, the hinges H and 15 are preferably arranged in front of the covers 12, 13, so that these open from the back to the front, which makes the maneuver easier. Fig. 1 shows the position in dash-dotted lines, which the lid 13 can take in its opening movement.

As shown in Figs. 5 and 7, the

The weapon is preferably designed in such a way that the cartridge belts 19 and 20 enter feeders 1 and 2 on the same side of the weapon »especially from bottom to top, and that the Belt links 21 and 22 are ejected on the opposite side. Furthermore, the weapon is preferably designed so that the cartridge cases on the same side as the

109836/0003

Belt links are ejected, as shown schematically by the arrow P of the pig. 5 and 7 is shown. The ejection opening the pod is in pig. 1 shown at 23.

Incidentally, it cannot be ruled out * that

the cartridge belts 19a and 20a in the feeder on opposite sides Sides enter, and that the belt links 21a and 22a from the weapon in the in Pig. 8 ejected manner shown will. This training can be interesting if the gun is arranged horizontally and one belt is fed from the right and the other from the left, with the ejection of the sleeves on the left takes place (as indicated schematically by the arrow P).

It is practically necessary to couple the two feeders * by mechanical devices, which are at the transfer of one of them from his rest position to his working position inevitably brings the other out of his working position Bring it into its rest position and hold the two feeders in their chosen mutual positions.

These facilities are expedient by

a fork 24 is formed which is guided in such a way that it is slidably displaceable transversely to the weapon and with the feeders 1 and 2 is connected in such a way that it does not interfere with the expansion of the same. For this purpose, the fork has grooves 25 (Pig. 5 to 8), which each cooperate with a pin 26 attached to the feeder in question and in the direction of the one carrying this feeder Pin 7 or 7a or 7b are open.

The transverse displacement of the fork 24 is preferably carried out by a device guided in the longitudinal direction of the weapon Slider 27 and a lever 28 which is pivotable on the weapon and connected to the fork 24, with between the Slider 27 and the lever 28 provide a kinematic connection

109836/0003

is seen which the longitudinal sliding movement of the first into a Rotational movement of the second converts.

In particular in Pig. 3 and 4, the lock box 9 has an axle 29, which passes through the slider 27 in a longitudinal slot 30, and on the free end of which the lever 28 is placed. Perner the slider 27 has an edge strip which slides along a longitudinal wall 9a of the lock box, so that it cannot rotate about axis 29. As a result, the slider 27 can only perform a longitudinal translation movement, during which the axis 29 ″ moves in the slot 30. The shooter can generate this movement of the slider 27 by means of a direct or indirect actuation (esp. by means of a cable pull, by means of a hydraulic, pneumatic, electromagnetic actuation or the like »), which e.g. engages on a projection 27ja of the slider 27,

D _e r lever 28 has a head 28a with an arcuate in plan Porm as Pig. 3 and 4 show, and a dovetail-shaped profile, so that the head can remain in a groove 31 formed in the fork 24 in any position thereof. The lever 28 carries two rollers 32 and 33 on the side of the slider 27, both of which work together with a cam 34 protruding from the slider 27.

to work. This crouch has an axis X-X of the weapon parallel plane 34a and curved paths 34b_ and 34c ,, with which the rollers 32 and 33 cooperate. These two rollers are designed so that they alternately roll on the plane 34a.

The above weapon works as follows: In the one shown in Pig.1,3 and 5

109836/0003

The position of the feeder 1 is such that its first cartridge A does not lie on the path of the closure 3. The feeder 2, on the other hand, has a position in which its first cartridge B "lies on this path" the cartridges of the belt 20 inserted into the weapon and fired In this position, as in Pig, is supported. 3 shown, the roller 32 from the plane 34a. The lever 28 can therefore do not rotate clockwise about the axis 29, so that the fork 24 is in Pig. 3 do not move upwards can. The feeders 1 and 2 are therefore locked in the positions they have assumed.

If the shooter now wants to fire grenades belonging to the belt 19, he moves the slider 27 in Pig. 3 to the right until it is in the position of the pig. 4 is coming. During this movement, the roller 32 initially exceeds the in Pig. 3 section of level 34a lying to the left of it. As soon as the role has arrived at the point of the curved path 34b_ is, the lever 28 is no longer locked. At this moment, the roller 33 reaches the curved path £ 34, whereupon it exceeds and thereby granted the lever 28 a clockwise rotation. This rotation has the displacement of the fork 24 upwards and thus the transfer of the feeder 2 into the

Rest position and the feeder 1 in the working position to the pole. The two feeders then take one to the one in Pig. 5 position shown a symmetrical position. Finally, the slider 27 continues its stroke toward the right, the roller 33 comes woduroh on the cam track 34a and, therefore, the lever 28, the G _a bel locked 24 and the two feeder ·

From Pig. 1 shows that the articulation

the feeder 1 and 2 by means of one or two to the Aohse X-X

109836/0003

allows the weapon to have parallel axes »to reduce the transverse extent of the weapon at the point of the feeder. It is sufficient namely a rotation through a relatively small angle to the first cartridges A and B from their Buhestellungen in to bring their jobs. As a result of this double The part of the feeder furthest away from the axis of the weapon experiences only a relatively small amount of pivoting Shift in the radial direction, so that the space required for actuating the feeder is small compared to the is what would be required if the pivoting of the feeder about one or two axes with a different position ■ became.
