    Marking the barrel of a firearm
    The invention relates to the marking of the barrel of a firearm, in particular a pistol, a rifle, or a carbine, in accordance with the introductory part of claim 1.
    As it passes through the lobe of a firearm, the projectile is deformed by the contacts with the inner surface of the barrel, which can serve to assign the weapon from which it was fired to a missile projectile. This option has been used for many years in forensic advantageous, but it came through the ever better, more accurate, and thus provided from weapon to weapon with fewer deviations of the inner surface of the runs to make such differences were more difficult to identify. For some years, there are now running cross-sections, which no longer consist of trains and fields as before, but have a polygonal cross-section and are called "polygonal runs" for short. Since the angular position of the polygon changes continuously along the axis of rotation, the projectile rotates about its longitudinal axis.
    The transitions between the individual, rectilinear polygonal sections are rounded and in this case a matching with the cross section of the projectile takes place such that the entire cross-sectional area of the run corresponds to the cross-sectional area of the projectile. The caliber measure is thereby determined for an even-numbered polygon (the polygons that are mostly used are hexagons) between two opposite rectilinear sections, the arcuate connecting pieces thus being "outside" the area determined by the caliber. The "caliber circle" is thus generally the innermost circle of the rectilinear polygon sections. These polygonal barrels are produced by cold working a blank over a mandrel having the desired cross section. In particular, runs thus formed with each other are so indistinguishable from one another that in general it is not possible to assign a projectile to a given run, or to exclude a predetermined run. This represents a significant disadvantage in terms of forensics.
    There have been and still are some proposals to provide traditional runs with trains and boxes with markings that allow such assignment completely independently of the race. Reference is made to US 6,796,073, US 2001/0029690, US 4,175,346 and AT 402,702. The contents of these publications are incorporated by reference into the present application for the countries where this is legally possible.
    The methods for applying markings mentioned in these documents are completely unsuitable for polygonal barrels. There is thus a need for a corresponding label and a method for its application.
    It is an object of the invention to specify such a method or a marker obtained therewith. The quality of the barrel must not be compromised and the costs of production should not rise noticeably.
    According to the invention, these objects are achieved by the measures indicated in the characterizing part of claim 1. In other words, the mandrel has a helically extending groove on its surface, which is located in one of the arcuate transitions between the rectilinear polygonal sections and whose width is so small that in one embodiment neither its side surfaces nor its bottom encircles the inner circle the straight polygonal sections intersects, it is thus entirely outside the Innkreises, thus preferably also the caliber circle. This means that a tangential arrangement of this Innkreis is possible, or the formation of a cylindrical groove bottom, but such an extreme approach to the caliber circle and its exceeding is advised only in special cases.
    As can be seen from this brief explanation, the provision of the groove on the dome requires virtually no extra work in comparison to the production of conventional domes, the run production itself does not make any difference to the production of conventional polygonal barrels that another dome is used, changes in the production Nothing.
    Interestingly, the advantages of the polygonal barrel are not affected by the provision of the groove in the dome, which leads to the formation of a corresponding strip-shaped projection in the barrel, so by the preferred inventive measure to stay outside the Kaliber circle, the gas seal and thus the muzzle velocity of the Projectile and also and the higher life expectancy compared to the runs with fields and trains not lowered. Even the easier cleaning of the inside of the barrel is retained.
    The invention will be explained in more detail below with reference to the drawing. 1 shows a polygonal cross-section with six straight polygonal sections, FIG. 2 shows the detail II of FIG. 1, FIG. 3 shows a variant of a polygonal cross-section and FIG. 4 shows the detail IIII of FIG. 3.
    In Fig. 1, the cross section of a polygonal barrel 1 with six rectilinear Polygonalbschnitten 2 is shown whose Innkreis 3, preferably the Kaliberkreis, the Kalibermaß corresponds. The arcuate regions or sections 4 lying outside the caliber circle balance the total area of the running cross section (without consideration of the strips 5) on the overall cross section of the projectile. In each of the six arcuate sections 4 is centrally located a radially inwardly projecting bar 5, the depth t is so small that neither the side walls of the bar nor their front wall intersects the Innkreis 3, the bar is in this embodiment entirely outside the caliber circle or at him.
    3 and 4 show a variant with a triangular shape of the strips 5 and with an arrangement of the strips 5 in the transition between the polygonal sections 2 and the arcuate areas 4, thus twelve strips 5 are provided. Again, their depth t is chosen as in the first variant; that is, the strips 5 do not protrude into the Innkreis 3.
    The reduction in the cross-sectional area of the barrel through the strips 5 is preferably not taken into account, but it is possible to do this in whole or in part, especially when numerous strips, for example more than one in or at one or more of the arcuate sections 4 are provided.
    In the illustrated first exemplary embodiment, in each of the six arcuate sections 4 there is provided centrally, as seen in the circumferential direction, a radially inwardly projecting bar 5; for reasons of symmetry, this or at least the arrangement of symmetrical bars is preferred.
    For reasons of clarity, the strips in both variants are dargestcllt to KaUberkreis reaching, this is, as explained above, not necessary.
    In polygonal runs with an odd number of straight sections 2 there is always an Innkreis 3, which preferably corresponds to the caliber circle, for these rectilinear sections, so that there, the invention is easily applicable. If per arched section 4 zw'ei strips 5 are provided, they can also, as in the second embodiment, be arranged directly at the transition to the rectilinear polygonal sections 2 and then preferably have a triangular shape and can in a rounded manner in the arc section 4 and tooth-like steeply into the rectilinear section 2, as shown in FIG. 4 shows a detail.
    Of course, other forms of training for the strips 5, in particular rounded, possible, to consider is only the production of grooves on the cathedral, the flow of the running material during cold forging and the stress of the materials of Dom and running on the one hand in the production, on the other hand in the Use, of the barrel. In the knowledge of the invention, it is no problem for the person skilled in the art of cold forging polygonal barrels to determine the corresponding shapes and dimensions, possibly with the aid of a few experiments.
