## Background
This specification for the instant application should be granted the priority date of May 15, 2004, the filing date of the corresponding German patent application 10 2004 024 302.6 as well as the priority date of Apr. 28, 2005, the filing date of the corresponding International patent application PCT/DE2005/000787.
BACKGROUND OF THE INVENTION
The specification incorporates by reference the disclosure of German priority document 10 2004 024 302.6 filed May 15, 2004 and PCT/DE2005/000787 filed Apr. 28, 2005.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
The present invention relates to a belted magazine for an automatic shell firing weapon mounted on a gun carriage.
Magazines of the aforementioned kind are generally known. They are usually configured as an open magazine that is located on one side next to the weapon. That results in a disadvantageous distribution of weight and a large rotational diameter of the pivotable weapon. Furthermore, the ammunition is not protected from atmospheric influences and whipping of the belt can damage the shells.
It is an object of the invention to configure a magazine in such a way that an optimally balanced distribution of weight and a small rotational diameter are achieved. It should furthermore be possible to guide the belt in such a way that whipping is avoided.
SUMMARY OF THE INVENTION
This object is realized, according to the invention, by a magazine that is adapted to contain a belt that in turn is adapted to be withdrawn from the upper side of the magazine and supplied to the weapon, wherein the magazine comprises two closed magazine portions that are interconnected by a closed transfer channel, wherein the magazine is disposed on the front side of the gun carriage in such a way that the two magazine portions are disposed on opposite sides of the weapon and the belt is adapted to be disposed in the magazine such that in a fully loaded state of the magazine a front section of the belt, as viewed in the direction of withdrawal of the belt from the magazine, is adapted to be disposed in a first one of the magazine portions that is disposed on the belt supply side of the weapon, wherein an upper part of the first magazine portion is provided with a removal opening that faces the weapon, wherein a rear section of the belt is adapted to be disposed in a second one of the magazine portions that is disposed on an opposite side of the weapon, and wherein a middle section of the belt is adapted to be guided through the transfer channel that interconnects the first and second magazine portions.
It is a fundamental concept of the invention to configure the magazine in such a way that the ammunition is essentially distributed evenly on both sides of the weapon. This is achieved in that the magazine is comprised of two closed magazine portions that are connected to each other by means of a likewise closed transfer channel. The entire magazine is attached below the weapon in such a way that each of the two magazine portions is located on an opposite side of the weapon. Due to that configuration, the magazine requires only little space on the sides of the weapon and enables a reduction of the rotational contour. Since the magazine is closed except for a removal opening, a good protection against atmospheric influences is provided. In a particularly advantageous embodiment, special guide means in the interior of the magazine such as a guide plate, a separation bar, a guide claw and a glide film, which is cushioned for dampening purposes, prevent damaging of the individual shells when the belt is removed. The magazine according to the invention can furthermore be configured and positioned below the weapon in such a way that it doesn't block the viewing of target optics located below the weapon.
The attachment of the magazine can be realized in a simple manner by suspending and locking it in place.

DESCRIPTION OF SPECIFIC EMBODIMENTS
FIG. 1 shows an automatic shell firing weapon 1, located on a base plate 11 and mounted on a gun carriage 1.1. A belted magazine 2 is attached to the gun carriage in the area in front of and below the weapon. The magazine 2 is comprised of two magazine portions 2.1 and 2.2 that are connected by means of a transfer channel 2.3. The magazine 2 is attached to the front side of the gun carriage 1.1 in such a way that the magazine portions 2.1 and 2.2 are located on opposite sides of the weapon 1.
The magazine 2 is configured as a closed magazine with a removable cover 2.4 that jointly covers the two magazine portions 2.1 and 2.2 and the transfer channel 2.3.
In the mounted condition according to FIG. 1, the magazine has a recess 9 in the area of the bottom wall of the transfer channel 2.3 between the magazine portions 2.1 and 2.2. The magazine 2 is attached to the gun carriage 1.1 in such a way that the transfer channel is located below the weapon tube and the recess 9 enables the target optics 10 located below the weapon to see through.
The magazine 2 and its manner of operating are described below in more detail with the aid of FIGS. 2 through 7.
As can be seen in the drawings, the interior space of the first magazine portion 2.1 is connected to the interior space of the second magazine portion 2.2 by means of the transfer channel 2.3. The belt that carries the shells is introduced into the magazine 2 in such a way that, when the magazine is fully loaded, a front section 3.1 of the belt is situated in the first magazine portion 2.1, which is located on the belt supply side of the weapon 1. On the side facing the weapon 1, the first magazine portion 2.1 is provided with a removal opening 2.11 through which the belt can be withdrawn and supplied to the weapon. A second section 3.2 of the belt is located in the second magazine portion 2.2, and a middle section 3.3 of the belt, which connects the first section 3.1 and the second section 3.2, is guided from the second magazine portion 2.2 to the first magazine portion 2.1 through the transfer channel 2.3. The first section 3.1 of the belt is positioned in the first magazine portion 2.1 in a meander shaped manner. In order to avoid whipping of the belt when the first section 3.1 of the belt is withdrawn, the side wall 2.12 opposite the removal opening 2.11 of the first magazine portion 2.1 is provided with a guide plate 4 that supports and guides one side of the belt loops in the first magazine portion 2.1. The guide plate 4 extends from the lower part of the first magazine portion 2.1 upwardly to the removal opening 2.11 and can be swiveled about a swivel axis 4.1, which is located in the area of the removal opening 2.11, into the interior space of the first magazine portion 2.1. When the first magazine portion 2.1 is emptied by withdrawing the first section of the belt 3.1, the guide plate 4 is automatically guided inwardly by means of a spring element. In that manner, the guide plate 4 uninterruptedly supports the remaining shells 3.4 that are attached to the belt until it reaches a final position, represented in FIG. 3, in which it is arrested. FIG. 3 shows the magazine in the state in which the belt loops of the first section 3.1 are withdrawn from the first magazine portion 2.1 and the middle section 3.3 of the belt is guided through the first magazine portion 2.1 directly to the removal opening 2.11. The peripheries of the shells thereby rest against the guide plate 4, which has been swiveled inwardly.
Furthermore, a separating bar 5 for guiding the shells and the belt is located on the side wall 2.13 below the removal opening 2.11 of the first magazine portion 2.1. The separating bar 5 can be swiveled about a swivel axis 5.1, which is located on the side wall 2.13, toward that side wall. When the first magazine portion 2.1 is fully loaded, the separating bar 5 separates the last belt loop of the belt section 3.1, which is positioned in a meander shaped manner, from the belt section 3.3 that enters from the transfer channel 2.3. In that manner, it is avoided that shells lie directly on top of each other. When the first magazine portion 2.1 is emptied, the separating bar 5 automatically swivels into the position represented in FIG. 3 and is thereby converted into a guide means when the separating function in no longer required.
The second portion 3.2 of the belt is positioned in the second magazine portion 2.2 in a spiral shaped manner. A guide claw 6, disposed so as to be pivotable about a swivel axis 6.1 in the direction of retraction of the belt, extends around the end of the belt. The guide claw 6 supports the second section of the belt when it is unrolled from its spiral position and avoids jams.
As shown in particular in FIG. 4, the side walls of both magazine portions 2.1 and 2.2 and of the transfer channel 2.3 are provided with spacer beads 7 that project inwardly and extend in the direction of retraction of the belt. They serve for guiding the shells 3.4.
The bottom or base 2.5 of both magazine portions 2.1 and 2.2, of the transfer channel 2.3 and, if required, the inside of the cover 2.4 are lined with a cushioned glide film, so that the shells that are positioned in the magazine 2 in a direction perpendicular to the bottom 2.5 and to the cover 2.4 are guided easily and are not damaged.
Behind the respectively first shell 3.41 that is positioned at the supply end, the belt can be suspended in a notch 8, represented in FIGS. 5 through 7, which is located in the upper side wall of the first magazine portion 2.1 on the edge of the removal opening 2.11. Therefore, when the belt is removed from the weapon 1 in the partially emptied state of the magazine, the belt does not fall back into the magazine such that the supply end of the belt would not be reachable any more. As can be viewed in FIGS. 6 and 7, the end of the belt is arrested on the removal opening 2.11 and cannot fall back into the magazine.
When the belt is supplied to the weapon 1, starting with the fully loaded state according to FIGS. 2 and 6, the belt is continually drawn out of the magazine 2. Initially, the section 3.1 of the belt that is positioned in the first magazine portion 2.1 in a meander shaped manner is withdrawn until the state represented in FIG. 3 is reached. Subsequently, the middle section 3.3 and the second section 3.2 of the belt from the second magazine portion 2.2 are drawn out through the transfer channel 2.3, until the magazine is emptied entirely, as represented in FIG. 4. With the cover 2.4 removed, the magazine 2 is reloaded with a new belt.
