Technical field
[0001] The invention relates to an apparatus for keeping linked ammunitions deposited in
a box or magazine with bays separated by divider walls from flowing from one bay to
another to reduce or avoid the risk of possible entangling or jamming of the ammunition.
Background of the invention
[0002] Ammunition boxes are used to store large quantities of ammunition to supply machine
guns and other firearms with ammunition. The ammunition is usually individual bullets
that are joined together with links forming a continuous belt of ammunition and then
folded into ammunition boxes from where the linked ammunition is fed to the weapon.
[0003] A conventional ammunition box is most often box-shaped where the width is narrow
compared to the length and height. The ammunition box may also be divided into several
smaller chambers or bays by divider walls, the divider walls herein referred to as
partitions or baffles, where each chamber stores a certain amount of the total linked
ammunition. The width of the ammunition box or chambers is wide enough to receive
the width of the linked ammunition. In this patent application it is referred to ammunition
boxes with divider walls, baffles or partitions, and chambers or bays.
[0004] When pulling linked ammunition out of a horizontally leveled and/or stationary ammunition
box during firing the conventional ammunition boxes usually work as intended. But
once the ammunition box is tilted or exposed to vibration, which are two common scenarios
when mounted on a moving vehicle, unless a means for retaining the ammunition in the
box where it was placed on filling of the box, the linked ammunition starts to move
from one chamber to another within the ammunition box causing interlocking and jamming
of ammunition and subsequent loss of weapons fire. The reason for the interlocking
and jamming is the non-symmetric design of the bullets. The bullets have a pointed
projectile end and a wider powder cartridge base. When the linked ammunition starts
to move from one chamber to another within the ammunition box the pointed projectile
end has a tendency to get entangled between the bullets in the linked ammunition belt
that is being fed to the weapon or fall down on top of the other ammunition already
in the chamber in such a way that it causes interlocking and jamming.
[0005] This problem is especially apparent when the ammunition box is tilted causing a negative
or positive pitch. During pitch the linked ammunition has a tendency to fall towards
the lowest point in the ammunition box due to gravity, thereby falling from one chamber
to another which can cause the already mentioned interlocking and ammunition jamming.
Another problem is the siphon effect that will occur when one chamber is emptied during
firing and the level of linked ammunition gets below the neighboring chamber's level.
When this occurs the linked ammunition will start to move from one chamber to the
next due to the siphon effect which causes interlocking and ammunition jamming, unless
a means for retaining the ammunition in the box in such a way as to preventing the
siphon effect to occur. The siphon effect problem is also present on horizontally
leveled and/or stationary ammunition boxes.
[0006] The main goal of the invention has been to stop the undesired effect of linked ammunition
moving from one chamber to another within the ammunition box and keep it in place
like it was originally loaded into an ammunition box which does not include a means
for retaining the ammunition in the box to prevent it from moving from one chamber
to another.
[0007] European patent
EP0430565B1 discloses a magazine for storing a belt of ammunition, the magazine comprising a
box like container having a plurality of spaced partitions to subdivide the interior
of the container into bays, each partition having an upper edge, and an anti-siphon
member supported on the upper edge of each of the spaced partitions. Each anti-siphon
member is supported on said upper edge of its respective partition for limited pivotal
movement. Each member has an integral projecting finger movable between retracted
and extended positions relative to the peripheral surface of rollers mounted in positions
above the edges. Upon withdrawal of an ammunition belt loaded in the container with
multiply folded serpentine portions thereof deposited in each bay and with interconnecting
loop portions thereof draped over the rollers from one bay to an adjacent bay, the
fingers assume the retracted positions to permit movement of the belt out of the bays
directly to an exit port of the container and assume the extended positions engaging
the interconnecting loop portions of the ammunition belt to prevent syphoning movements
thereof into the bays as the serpentine belt portions are being withdrawn therefrom
to the exit port.
[0008] US patent no. 2,710,561 discloses in an ammunition box having partitions forming a series of open compartments
wherein a cartridge belt may be stored by looping the belt into the compartments over
the partitions, a pawl connected to an upper end of the partition for preventing retrograde
movement of the belt with respect to the compartment. The pawl is pivotally connected
to the partition so as to allow limited pivotal movement of the pawl from a rearwardly
projected position to a generally inline position with respect to the partition wall
for allowing the belt to pass thereover, towards an outlet.
[0010] By designing ammunition boxes with divider walls and baffles, thereby dividing the
ammunition box into several smaller chambers or bays, and then placing a simpler and
more robust ammunition retainer device on top of each baffle, the present invention
provides a further solution to the problems related to linked ammunition moving from
one chamber to another within the ammunition box, thereby reducing ammunition jamming
often caused by tilt and vibration of the ammunition box. The siphon effect problem
has also been solved.

[0017] Figure 1 illustrates front in a view drawing, a short section of linked ammunition,
hereinafter referred to as ammunition 6. The ammunition 6 comprises a plurality of
cartridges linked together, such as for example by way of a plurality of clips 5.
Each clip has first grip part and a wider second grip part. In the second grip part
is an opening, adapted to the outer shape of the first grip part. The first grip part
is adapted to clip onto and hold a central part of a first cartridge, while the second
grip part is adapted to clip onto and hold parts of a corresponding second cartridge
located to the sides of the central part. Thus, the central part of the second cartridge
is left free for it to be held by a first grip part of a corresponding next clip,
to form a belt of linked cartridges.
[0018] Figure 2 is an illustrates in a schematic cross section view a typical well-known
ammunition box or magazine filled with linked ammunition 6, the linked ammunition
6 forming a continuous belt located in bays in the ammunition box or magazine container
formed by baffles 3. The linked ammunition is available to be pulled out of the container
at an exit of the ammunition box or magazine container, illustrated by the arrow on
the right hand side of the drawing. For continuity of the belt between bays, the linked
ammunition is run over upper edges 1 of the baffles 3. The typical well-known ammunition
box or magazine illustrated in figure 2 does not include means to restrict or impede
movement or sliding of the belt of linked ammunition 6 over the upper edges 1 of the
baffles 3.
[0019] In figures 3 and 4 is illustrated an advantageous ammunition retainer bracket 10
embodiment of the apparatus of the invention. The retainer bracket 10 comprises an
elongated body having first and second ends 11 and 13, respectively. The retainer
bracket 10 comprises sets of spaced tabs. The sets of tabs are a first set of central
tabs 12a and 12b, located at a first position between the first and second ends, and
a second set of end tabs 14a and 14b, located at the second end. Central tab 12a and
end tab 14a are located on a first side of the elongated body to constitute a first
pair of tabs, and central tab 12b and end tab 14b are located on a second side of
the elongated body to constitute a second pair of tabs. The spacing of the central
tabs 12 and the end tabs 14 is adapted so as to allow the second grip part of clips
5 to be accommodated between them, while, as illustrated in part in figures 5 and
7, allowing parts of cartridges located outside the second grip part of clips 5 to
rest on the tabs when the belt of linked ammunition 6 is placed over the retainer
bracket, and the tabs are dimensioned for extending into a space between adjacent
ones of the cartridges forming the belt of linked ammunition 6.
[0020] In an advantageous embodiment of the invention, tabs 12a, 12b, 14a, and 14b are curved
or shaped in conformity with a curvature of a circular cross section of the part of
the cartridges of the belt of linked ammunition 6 that the tabs are to provide a rest
for. The curved shape, however, could be replaced by other shapes, provided that the
shape allows the belt of linked ammunition to be pulled off the upper edge 1 of the
baffle 3 of the ammunition box or magazine container, as illustrated schematically
in figure 8.
[0021] Figure 6 illustrates in a cross section view schematically the ammunition box or
magazine container of figure 2 provided with retainer brackets 10 according to the
invention at the upper edges 1 of the baffles 3, and a belt of linked ammunition filled
into the bays between the baffles in the shape of a serpentine, and run over the upper
edges 1 to form continuity of the belt as it runs from one bay to the next.
[0022] Advantageously, the part of the elongated body of the retainer bracket keeping the
first pair of tabs on one side of the spaced from the second pair of tabs, would generally
be shaped as a half-pipe, and the tabs extending from the body of the retainer bracket
10 such that the end of the tabs are at a distance of approximately between one half
and two thirds of the diameter of the cartridge away from the body. Accordingly, in
an embodiment of the invention designed to be employed in an ammunition box or magazine
container with baffles adapted for 7.62mm (0.30 cal) linked ammunition using clips
5 that link the cartridges with spacings of about 3mm, the diameter of the half-pipe
body should be about 18mm, the first pair of tabs should have a separation from the
other pair of tabs of about 3 8mm measured on the circumference of the body, the tabs
should protrude on respective radii of the half pipe shape to a distance of about
5mm, the tabs of each pair of tabs should have a separation of about 28mm, and the
tabs should have a cross section of about 2mm by 6mm. For other types of linked ammunition,
such as for example for 5.56mm (0.22 cal) linked ammunition, the dimensions of the
retainer bracket are scaled accordingly.
[0023] In an advantageous embodiment of the invention, the tabs are located on the circumference
of the body, and also shaped and dimensioned such that when the belt of linked ammunition
is placed onto of, and partly folded around the retainer bracket, a group of three
cartridges are accommodated above and between the first and second pairs of tabs,
while the tabs are brought into close contact with the next cartridges on either side
of the group. The close contact will insure an improved stability of the linked ammunition.
In the aforementioned close contact arrangement, one could take advantage of the resilience
of the clips 5, to obtain a "soft" locking of the cartridges to the protruding tabs
of the retainer bracket of the invention. The illustration of figure 7 shows a first
pair of tabs 12a and 14a dimensioned to closely fit the spacing between the cartridges
of the belt of linked ammunition, and also spaced from the second pair of tabs 12b
and 14b (not visible) along the circumference of the body, and also angled away from
a radius of the body, such that a slight force is applied to the cartridge located
below the tab to keep the cartridge in place as shown. The same is illustrated in
the schematic side view of figure 8, which also illustrates how the linked ammunition
would be pulled of the retainer bracket 10 by the pull symbolized by the arrow, in
a rolling movement about the adjacent cartridge next to the cartridge located immediately
below the tab, as one bay is about to be emptied and ammunition is about to be supplied
from the neighbouring bay.
[0024] To optimize the performance of the retainer bracket 10 of the invention, filling
of an ammunition box or magazine container 2 employing the retainer brackets 10 of
the invention at the upper edges of partitions 3 should be as illustrated in figure
6, with the belt of linked ammunition 6 filling the bays in a serpentine fashion with
start from the bottom of the bay, the uppermost layer of the serpentine ending next
to and below the upper edge 1 of the partition 3 to which the retainer bracket is
attached, and then to continue over the retainer bracket, along the partition 3 and
down to the bottom of the next bay into which the belt of linked ammunition is further
disposed to fill that next bay in a serpentine like fashion.
[0025] The apparatus of invention can be seen as employed in the exemplary ammunition boxes
depicted in figures 9, 10, 11 and 12. The ammunition boxes include at least one section
including the ammunition retainer bracket of the invention, adapted for a 7.62mm (0.30
cal) bullet, such as illustrated initially in figure 1, although that caliber is employed
in this disclosure for illustration purpose only, as the ammunition retainer of the
invention can be adapted for use on different calibers.
[0026] The ammunition retainer of the invention stops the linked ammunition from moving
from one chamber to another when the ammunition box is exposed to tilt and/or vibration,
and also eliminates the siphon effect. This is done by actually locking the linked
ammunition belt in place at the top of each baffle with the ammunition retainer of
the invention, and still be able to freely pull the linked ammunition out of the ammunition
box, as the ammunition retainer of the invention is not hampering the ammunition feeding
or flow. The typical ammunition boxes depicted in figures 9, 10, 11 and 12 are particularly
well suited for being provided with the ammunition retainer of the invention. In the
illustrations of figures 9, 10, 11 and 12, ammunition retainers 10 according to the
invention are shown on top of baffles 3, which combined with a further divider wall,
shown as the vertical divider wall 2, divides the ammunition box into ten chambers
4, where chambers on one side of the divider wall 2 is reserved for 7.62mm (0.30 cal)
linked ammunition, and chambers on the other side of the divider wall 2 is reserved
for 5.56mm (0.22 cal) linked ammunition. The ammunition retainer according to the
invention is present on top of the baffles in both sides of the ammunition box.
[0027] There are two significant aspects to consider in respect embodiments of the present
invention, although also in respect of the general inventive concept of the present
invention. These aspects have to some extent been indicated in the disclosure above,
and will now be further elucidated by the following discussion.
[0028] A first aspect to be discussed herein, is that the invention is ammunition is linked.
The linking member, herein also referred to as the clip 5, that keeps the individual
cartridges joined together is designed in such a manner that the cartridges have a
little gap between them, as can be seem from the illustrations of figures 1, 5 and
7. This gap is taken into consideration in the design of the ammunition retainer apparatus
of the invention. The second aspect to be discussed, is the way in which the ammunition
box is to filled or loaded to take further advantage of the stabilizing properties
of the ammunition retainer apparatus of the present invention.
[0029] In respect of the first aspect, when the ammunition belt is folded over a baffle
provided with the ammunition retainer of the invention, it gets locked in place at
the top of the baffle. This is accomplished by the design of the inventive ammunition
retainer apparatus proposed herein, where four tabs, two on each side, are located
such that each of two on the same side will come into place between two adjacent cartridges
in the linked ammunition belt. In respect of this first aspect, reference is made
to figures7 and 8, teaching how these tabs are designed such that they fit into the
space between two adjacent cartridges, while not interfering with the linking member
that joins adjacent cartridges together. In this way, the linked ammunition belt is
allowed to rest on the tabs of the ammunition retainer of the invention, regardless
of tilt or vibration on the ammunition box, or the siphon effect. The ammunition belt
is not allowed to move, and the ammunition will stay in the chamber into which it
was originally loaded, until it is pulled out of the box in a normal fashion. Thereby,
the apparatus of the invention is eliminating the possibility of ammunition moving
from one chamber to another, which is known to causing interlinking and, hence, ammunition
jamming.
[0030] In respect of the second aspect, to optimize the exploitation of the advantageous
effect of employing the ammunition retainer apparatus of the invention in an ammunition
box or magazine with internal baffles, the ammunition box should be loaded or filled
in a certain way. With regard to this second aspect, particular reference is made
to figure 6, for an illustration of an example of an advantageous loading pattern.
The linked ammunition should to be loaded in such a way that one chamber is filled
at a time, then the ammunition belt is folded over the baffle which is provided with
an ammunition retainer of the invention on top for "locking" the ammunition belt in
place. In the ammunition box fully loaded or filled as illustrated in figure 6, the
continuation of the belt of linked ammunition is brought back over the ammunition
resting of the ammunition retainers on top of the baffles and to an ammunition box
exit which should be located over or in the vicinity of the upper part of the first
bay, thus allowing the belt to continue to be fed to the weapon. With the ammunition
box or magazine container loaded as described herein, when the belt of linked ammunition
is pulled out of the container, it is pulled over the underlying layer of ammunition,
to eventually roll over the ammunition retainer of the invention when a bay is about
to be emptied, thereby staying clear of the tabs. The operation is illustrated in
further detail in the schematic side view drawing of figure 8, where the "tail" cartridge
6, that is, the last cartridge of the ammunition belt in the bay to the left of the
baffle 3, gets lifted away from the tabs on the left hand side of the ammunition retainers
10 taps, to eventually roll over the baffle 3. The rolling movement is achieved by
retention of the cartridges to the right hand side of the "tail" cartridge 6 provided
by the tabs on the right hand side or the ammunition retainer 10, which tabs provide
a rest for the neighbouring cartridges. Thus, the "tail" 6 of the linked ammunition
belt will follow the path indicated by the curved arrow line, to be lifted, upwards
and to the left, and clear of underlying ammunition as well as clear of the tabs of
the ammunition retainer of the invention.
[0031] As discussed herein, for optimization of the performance of the ammunition retainer
apparatus of the invention, attention should be paid to obtain the best interaction
between the ammunition retainer and dimensional characteristics of the belt of linked
cartridges, to ensure good "locking" of the belt as it is in place over the ammunition
retainer, while balancing the retention force applied to the belt by the ammunition
retainer of the invention to the force provided by the weapon or its associated ammunition
drive means for pulling the ammunition from the ammunition box or magazine. In particular,
the angle at which tabs protrude from the body, the length, width and thickness of
the tabs, as well as the shapes of tabs are parameters that may be varied in the optimization
of the ammunition retainer of the invention for different types of linked ammunition,
different designs of ammunition boxes or magazines, and different types of weapons.
[0032] It should be noted, that although the invention has been disclosed herein by way
of examples, of which some have proven to be highly advantageous for the specific
types of ammunition used to illustrate the invention, the tabs on one side of the
elongated body may be shaped differently form the tabs on the other side of the body.
Different shaping of the various tabs may be find to be advantageous depending on
the way or pattern in which the belt of linked ammunition is loaded in the ammunition
box or magazine. As an example, when considering the loading pattern illustrated in
figure 6, in conjunction with the unloading patterns indicated in figure 6 by the
line towards the exit and the arrow indicating where and how the belt is pulled from
the magazine to unload the ammunition, and the detain of operation depicted in figure
8 and explained above, the tabs on the side towards the bay which is first emptied
could advantageously be angled, shaped and dimensioned in consideration of the direction
in which the belt is running along the divider wall 3 to the bottom of the bay to
the left of the wall and the direction of the lifting force applied to the "tail"
for "unlocking" the belt form the ammunition retainer. The tabs on the right hand
side of the body could be angled, shaped and dimensioned differently from the tabs
on the opposite side of the body, as the ammunition belt to the right hand side of
the ammunition retainer as illustrated by the example of figure 6 could approach the
retainer from a different angle, and it should be taken into consideration that the
belt of linked ammunition would be pulled more or less straight off the tabs without
the rolling movement of the linked ammunition that is seen on the other side of the
retainer.
[0033] In the illustrations and pictures ammunition with a 7.62mm (0.30 cal) caliber has
been used for illustration purpose, but the Ammunition Retainer can be adapted to
most ammunition calibers, link types and ammunition boxes where found suitable.
[0034] The ammunition retainer of the invention could be provided as a plurality of member,
to be assembled to form the ammunition retainer disclosed herein. However, in an advantageous
embodiment of the present invention, the ammunition retainer of the invention is produced
as a single, unitary member, in that it may be cost effectively stamped from a sheet
of metal, and even shaped during the stamping operation, or cast or molded in a single
piece, thus requiring no further machining or other operation for it to be ready to
be applied to or mounted on the ammunition box or magazine or to other element forming
part of the ammunition box or magazine. The inventive ammunition retainer disclosed
herein by way of example in the form of a separate bracket unit 10 to be mounted on
the ammunition box or magazine or a part of an ammunition box or magazine is considered
an advantageous embodiment in particular for applications for retrofitting existing
designs of ammunition boxes or magazines, although the ammunition retainer of the
invention is capable of being provided as an integral part of the ammunition box or
magazine, or as an integral part of a baffle or other means of the ammunition box
or magazine, such as means for providing the chambers or bays into which the linked
ammunition could be loaded for loading of the ammunition container.
[0035] In an embodiment of the ammunition retainer of the invention, in case the ammunition
retainer is adapted for retaining a plurality of cartridges between the first and
second pairs of tabs, additional tabs are provided, such as for example a third set
of tabs protruding from the body and located at a position along the circumference
of the body between the first and second pairs of tabs. Conversely, in case the ammunition
retainer is adapted for retaining one cartridge between the first and second pairs
of tabs, further tabs may be arranged to at least one side of the first or second
pairs of tabs. In yet a further advantageous embodiment of the ammunition retainer
apparatus of the invention, the tabs of a pair of tabs are positioned along the longitudinal
direction of the elongated body so as to maintain cartridges "locked" in place by
the ammunition retainer with the percussion cap proximal to a first side wall of the
linked ammunition container, while maintaining a space between the pointed bullet
end of the ammunition and a second side wall of the ammunition container located opposite
to the first side wall of the ammunition container. Maintaining the "locked" ammunition
in place by positioning the tabs as indicated herein, is effectively achieved by positioning
the tabs as illustrated in figure 7, wherein the elongated body is fitable across
the interior of the container in which the first and second side walls are separated
by a distance that exceeds that overall length of the ammunition unit as measured
from the percussion cap end to the bullet tip by about ten percent or more, thus allowing
some free space between the bullet tip and its adjacent second container side wall,
the end tab 14a to "lock" the cartridge at the percussion cap end is positioned at
the end of the body to be located proximal to the first container side wall, and the
corresponding central tab 12a is positioned to have a side facing the end tab 14a
located at the position of the "upper edge" of the clip 5 when the cartridge is in
place on the ammunition retainer with the percussion cap immediately next to the second
container side wall.
[0036] It should be noted that in an embodiment wherein the elongated body is shortened
while the positions of the tabs are maintained, also the central tabs 12a, 12b could
be termed "end tabs" 12a, 12b, as being located at a different end of the body, opposite
to the end at which the end tabs 14a, 14b are located.
[0037] The tabs of the ammunition retainer of the invention may be provided resilience as
suitable for maintaining the linked ammunition "locked" in position at the ammunition
retainer, such as for example by use of a material having inherent resilient properties
for the tab itself, or by attaching the tab to the body of the ammunition retainer
by a section of resilient material. Optionally, one or more tabs may be shaped to
provide resilience for advantageously locking the belt to the tab by way of the gap
between adjacent ones of two cartridges of the belt of linked ammunition cartridges,
such as for example by making the tab longer than shown in the accompanying drawings
and then folding back an outer part of the tab to a shape and dimension that will
allow it to be fit by some force into the gap between adjacent cartridges and in that
position exerting by spring action of the folded back portion counteracting forces
on both cartridges to increase friction for holding the cartridges "locked" to the
tab, also in case of a belt of linked ammunition cartridges with considerable variations
of dimensions of the gaps between cartridges.
[0038] The invention disclosed herein may be performed in a first method of providing an
ammunition box or magazine with the functionality of the ammunition retainer disclosed
above, in a second method of loading an ammunition box or magazine having the ammunition
retainer disclosed above with a belt of linked ammunition starting from the bottom
of a first bay via and over the ammunition retainer apparatus and on to a next bay
adjacent to the first bay including loading the first and bays with linked ammunition
in a serpentine like pattern and on to an exit of the box or magazine, or in a third
method for unloading linked ammunition from a loaded magazine wherein ammunition is
obtained by pulling linked ammunition from the loaded box or magazine via a path corresponding
to the one taught by the illustrating arrow and its associated line in figure 6 and
over the inventive ammunition retainer as taught by the illustration of figure 8 as
the next bay is being emptied and ammunition then is supplied from the first bay.
