Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a magazine for an automatic weapon,
especially for utilization in connection with caseless
ammunition.
[0003] The recoil forces of an automatic weapon affect the handling
of the weapon and the oscillation of the weapon barrel so that a
known automatic weapon of this kind has a relatively wide scatter
of hit pattern. In addition automatic weapons are inclined to
kick-up, against the restraining forces (i.e. from round-to-round).
An attempt is made to counteract the unrestrained effect of such a
stepwise increase in elevation, i.e. kick-up, by limiting the
number of rounds either automatically or by gunner intervention.
This is, however, possible only to a limited extent because long
bursts of fire are also usual. Such long bursts of fire are usually
a waste of ammunition.
[0004] 2. Discussion of the Prior Art
[0005] A conventional automatic weapon recoils along a damping path
each time a round is fired. This recoil-damping path can be from a
few millimeters up to a few centimeters long. After the recoil
damping movement, the weapon is again returned to the basic
position.
[0006] The ammunition feed transport and the ammunition feed are
thus usually in a defined position. In such cases, the magazine or
the magazine belt feed is usually also fixed.
[0007] For an automatic weapon, especially for caseless ammunition
where the weapon can move linearly in its axial longitudinal
direction in a housing, enabling the weapon to recoil unrestrained
along a relatively long recoil path determined and limited by a
recoil damper as described in copending German Patent Application
No. DE 10 2005 026 978.8-15, a fixed magazine or a belt feed of
this kind would mean that a complete magazine, together with all of
the ammunition, would always have to travel back with the weapon.
With a belt feed, it would be possible for the ammunition belt to
be dragged backwards and forwards in great loops.
SUMMARY OF THE INVENTION
[0008] The object of the invention, taking account of these
circumstances, is to provide a magazine for an automatic weapon of
the type mentioned in the introduction, in which the magazine with
all of the ammunition does not always have to travel back with the
weapon, or the belt feed does not have to drag the ammunition belt
backwards and forwards in great loops.
[0009] With the automatic weapon according to the invention, a
primary magazine for a large number of powder charges and a primary
magazine for a large number of projectiles are attached to the
weapon housing, and the weapon, that during a firing burst moves
backwards unrestrained in the longitudinal direction of the weapon
housing along a defined, relatively long recoil path, has a
magazine element for a small number of powder charges that travels
with it and a magazine element for a number of projectiles
corresponding to the number of powder charges that also travels
with it. A relatively small magazine element with a limited,
defined capacity for powder charges and a corresponding magazine
element for projectiles are thus provided on the recoiling weapon.
These two magazine elements move with the weapon during the recoil
movement. The primary magazine for powder charges, attached to the
weapon housing, and the primary magazine for projectiles, attached
to the weapon housing transfer a specific small number of powder
charges and projectiles to the respectively associated magazine
element of the weapon after each firing burst.
[0010] With the automatic weapon according to the invention, both
primary magazines and both magazine elements can be designed as
box-type magazines. The magazines can also be designed as drum
magazines or, for example, as stick magazines.
[0011] According to the invention, it is also possible for the two
primary magazines to have a belt feed device for belted powder
charges and an associated powder charge feed star and also a belt
feed device for belted projectiles and an associated projectile
feed star, with the powder charge feed star and projectile feed
star being mounted in the weapon housing parallel to the axis, and
with both magazine elements each having a transfer star associated
with the projectile feed star and a transfer star associated with
the powder charge feed star, with the transfer stars being arranged
with their axes parallel to each other and to the axes of the two
feed stars mounted on the weapon housing.
[0012] The two small magazine elements of the weapon are preferably
provided on opposite sides of the weapon barrel of the weapon and
axially offset relative to each other in the barrel longitudinal
direction, so that the magazines of the automatic weapon according
to the invention do not adversely affect each other.
[0013] A cross-slide is associated with each of the two small
magazine elements of the weapon. One feed element is expediently
associated with each of the two cross slides.
[0014] With the design of the automatic weapon according to the
invention fitted with belt feed devices, the relevant belt feed
device pulls the associated belt in until a preset number of
rounds, as required for a defined firing burst, are loaded into the
associated small magazine element. The relevant belt is then
separated. The moving belt feed device positions the ammunition in
the loading position. After returning to the basic position, the
relevant belt feed device pulls the next required number of rounds
into the associated small magazine element and again cuts off the
belt. This process is repeated.
[0015] With the automatic weapon according to the invention, when
the weapon is in the basic position, a corresponding large or
primary magazine transfers, e.g. loading strips with a defined
amount of ammunition. The ammunition return movement in the
particular magazine element can, for example, also be realized by
spring pressure or by exerting positive control by means of a
control cam.

DETAILED DESCRIPTION OF THE INVENTION
[0022] FIG. 1 is a cross-sectional view showing one embodiment of
the automatic weapon 10, especially for caseless ammunition. The
weapon 10 has a weapon barrel 12 and is guided in a weapon housing
14 in its longitudinal direction, i.e. at right angles to the plane
of the drawing (FIG. 1), so that it can move linearly. The weapon
10 can thus recoil unrestrained in the weapon housing 14 over a
defined recoil path during a firing burst. For this purpose, the
weapon 10 is arranged in the weapon housing 14 by means of guide
devices 16 to enable it to move linearly.
[0023] A primary magazine 18 for projectiles 20 and a primary
magazine 22 for powder charges 24 are attached to the weapon
housing 14. The weapon 10 has a magazine element 26 for powder
charges 24 and a magazine element 28 for projectiles 20. Both
primary magazines 18 and 22 and both magazine elements 26 and 28
are each designed as box magazines.
[0024] As can be seen from FIG. 2, in which identical details are
designated using the same reference numbers as in FIG. 1, a
respective cross-slide 30 or 32 is associated with the magazine
element 26 or 28 respectively, and a feed element 34 or 36 is
associated with each cross-slide 30, 32. The operation and action
of the cross-slides 30 and 32 and of the feed elements 34 and 36
associated with them are explained below in conjunction with FIGS.
4 and 5.
[0025] FIG. 2 is, furthermore, a schematic showing a position P1 of
the weapon 10 before the first shot and a position P2 of the weapon
10 before the second shot.
[0026] FIG. 4 is a schematic section showing the weapon barrel 12,
the magazine element 26 for powder charges 24, the magazine element
28 for projectiles 20, the cross-slide 30 for projectiles 20 and
the cross-slide 32 for powder charges 24, and also the feed element
34 associated with the magazine element 26 and the feed element 36
associated with the magazine element 28.
[0027] With the aid of the feed element 34, in the position shown
in FIG. 4, the powder charge 24 is transferred from the magazine
element 26 to the cross-slide 32 and, with the aid of feed element
36, a projectile 20 is transferred from the magazine element 28 to
the cross-slide 30. The cross-slide 32 is then moved in the
direction of the arrow 38 and the cross-slide 30 in the direction
of the arrow 40, so that, as can be seen from FIG. 5, the
projectile 20 and the propellant charge 24 are positioned axially
aligned with the weapon barrel 12, with the propellant charge 24
then-being detonated with the aid of a detonator 42, schematically
shown in FIG. 5 by an arrow. The cross-slides 30 and 32 are then
returned to the start position again as shown in FIG. 4, so that,
after a corresponding recoil of the weapon 10 in the weapon housing
14, the process described with reference to FIGS. 4 and 5 can be
repeated.
[0028] FIG. 3 shows an embodiment of the automatic weapon 10 that
is guided in a weapon housing 14 in its longitudinal direction such
that it can house linearly, at right angles to the plane of the
drawing (FIG. 3), so that the weapon 10 can recoil unrestrained in
a defined recoil path P1, P2, . . . in the weapon housing 14 during
a firing burst. In this embodiment, the two primary magazines have
a belt feed device 42 for belted powder charges 24 and a (not
illustrated) belt feed device for belted projectiles 20. The belt
feed device 42 for the powder charges 24 has a powder charge feed
star 44, and the belt feed device for the belted projectiles 20 has
an associated projectile feed star 46. Both these feed stars 44 and
46 are rotatably mounted on the weapon housing 14. Their axes are
oriented parallel to each other.
[0029] Both small magazine elements of the weapon 10 have a
transfer star 48 associated with the powder charge feed star 44 and
a transfer star 50 associated with the projectile feed star 46. The
transfer stars 48 and 50 are arranged parallel to each other and
parallel with the axes of the feed stars 44 and 46 mounted on the
weapon housing 14.
[0030] The weapon barrel of the weapon 10 is also designated with
the reference number 12 in FIG. 3.
[0031] The transfer stars 48 and 50 form corresponding small
magazine elements 26 for the powder charges 24 and projectiles
20.
[0032] The axially aligned arrangement of the particular powder
charge 24 and associated projectile 20 relative to the weapon
barrel 12 for each round of a firing burst can be realized in a
manner similar to that for the embodiment shown in FIGS. 1 and 2,
as has been described above in conjunction with FIGS. 4 and 5.
[0033] The invention can also be used for short, integral cased
ammunition. A moving magazine is then provided in a similar
manner.
