Abstract

To calibrate a triple-barrel weapon, with height and side settings for each barrel, a bracket (5) is rigidly fixed to the first barrel (1). An alignment holder (9) is fitted to the bracket (5) with a release mounting, so that the muzzle ends of the other two barrels (2,3) lie at a nominal position to the muzzle end of the first barrel (1). The three barrels (1-3) are loaded and fired. On an unacceptably large drift of the shot from the first barrel (1) at the target by the other two barrels (2,3), the alignment holder (9) is replaced to shift the muzzles of the barrels (2,3) in relation to the muzzle of the first barrel (1) to correct the drift.

Description

The invention relates to a method for height and side adjustment of the barrels triple-barreled weapon and a device for performing the method.

The invention relates to three-barrel weapons, in which the barrels on the rear end of the cartridge chamber are rigidly connected to each other and at which at the Muzzle ends a barrel holder is provided. This barrel holder is with one of the Barrels rigidly connected and used to store the other two barrels, for example a bore for supporting the end of the mouth of the second barrel and a bearing half-shell are provided for storing the muzzle end of the third barrel. The two others Barrels are axially displaceable relative to the barrel holder. The muzzle ends of the three barrels thus assume a predetermined position relative to each other.

The meeting point of all three runs should be within a specified tolerance range. at Triplets with rifle barrels of the same caliber, valid for hit images with at least five shots per run, the maximum spread is 100 meters 150 mm. If this tolerance range is not observed, it is necessary Adjustment devices to provide a height and side adjustment of the barrels enable.

From DE 38 34 304 C1, according to the preamble of claim 1 and 5, is an adjusting device for adjusting a front Known on a three-barrel weapon, in which an anchoring block with two Is soldered. There are one recess and three in the anchoring block Threaded holes provided. The setting device also include in the Threaded holes arranged adjusting screws and a guide sleeve in which the the barrel to be adjusted is stored without play. An anchor pin is attached to the guide sleeve, which is pivotally and slidably arranged in the recess of the anchoring block and can be fixed with the adjusting screws. The barrel is locked and locked here by turning the separate adjusting screws that put pressure on the anchor pin exercise and fix it in a desired position.

In a hunting rifle known from AT 372 520, one of the two bullets is included a shotgun soldered along its entire length using an intermediate rail. in the The area of the mouth end is an additional insert with the shotgun barrel and the soldered a ball barrel. The second ball barrel has at its front end of the mouth a lateral approach, which in a corresponding recess of the insert engages and can be fixed there by two mutually perpendicular adjusting screws. Here, too, the ball barrel provided with the shoulder is adjusted by Corresponding rotation of the two adjusting screws using additional nuts are secured.

The adjustment mechanisms described above have the disadvantage that an unintentional Loosening screws and wedges is possible, which changes the point of impact and thus a new height and / or side adjustment of the barrels becomes necessary.

There is a task, a method and an apparatus for height and side adjustment provide the barrels with a three-barrel weapon of the type mentioned, in which a one-off adjustment of the position of the muzzle ends is required and a later one unintentional adjustment of the positions is excluded.

This object is achieved with the features of claims 1 and 5. Advantageous Refinements of the method and the device that carry out the method enable, can be found in the subclaims.

The runs 1, 2, 3 mentioned below can be shot or ball runs act. In the exemplary embodiment according to FIG. 1, the first and second are concerned Ball barrel 1, 2 around shot barrels, while the third barrel 3 is a ball barrel. On the Mouth end of the first ball barrel 1, a socket 4 is placed, which has a flat base 5 carries, which is perpendicular to the soul axis 6 of the first barrel 1 in the space between the three Runs is arranged. This base 5 has a threaded bore 7 and two Pin holes 8 on. The socket 4 is soldered to the muzzle end of the barrel 1, wherein the bores 7, 8 have a precisely predetermined rotational position about the axis 6. In relation this predetermined rotational position is designated by a on the threaded bore 7.

Furthermore, a barrel holder 9 is provided, which has a through hole 10 and has two pin bores 11. The position of the bores 10, 11 corresponds to the position of the Bores 7, 8. By means of a screw 12 and the dowel pins 13, the barrel holder 9 on Base 5 are attached. The barrel holder 9 has a bore 14 for the end of the barrel 3 and a half-shell 15, against which the muzzle end of the barrel 2 to the system comes, which is biased for this purpose in the direction of the half-shell 15 with its rear end of the cartridge chamber is attached. The half-shell 15 is another one Half-shell 16 is provided, which comes to rest on the sleeve 4.

With the base 5, a barrel holder 9 is attached first, which is used as a standard holder is designated. In this standard bracket 9, the axes of the bore 14 and Half-shell 15 in terms of height and sides in relation to one another and to the axis of the soul 6, which corresponds to the nominal distance of the soul axes 17 and 18 to one another and to the soul axis 6.

With this standard barrel holder, each barrel 1, 2, 3 is then bombarded initially described. After all three runs have been shot at, the meeting point for runs 2 and 3 mediated relative to the meeting point of runs 1. Is the meeting point of the Runs 2 and 3 in a given tolerance range for the meeting point of run 1, then The standard barrel holder 9 remains in place. However, the meeting point location is one of runs 2, 3 or both runs 2, 3 outside the tolerance range, then the Normlaufhalterung 9 removed. It is replaced by one in which the axis of the Half-shell 15 and / or the bore 14 assume a position relative to the axis 6 of the soul compared to the position of the standard barrel holder is changed so that the meeting point of the barrel 2 and / or barrel 3 is within the permissible deviation. For example, if the Meeting point of run 3 above the permissible deviation, then one Normlaufhalterung used, in which the height distance between the axis of the Bore 14 and the core axis 6 is less than in the standard barrel bracket.

The core axes of the runs 2, 3 to one another and to the core axis 6 are thus aligned that the meeting points are within the permissible tolerance range.

Since the positions of the core axes of the barrels 1, 2, 3 cannot be changed by the barrel holder 9 , there can be no unwanted adjustment of these positions. In the Embodiment according to Figures 2 and 3 is the socket 4 with the front end of the first run 1 not soldered, but screwed. This type of screw connection is in itself known.

In the embodiment according to FIGS. 4 and 5, the barrel 2 is on the muzzle end a socket firmly screwed on, the outside diameter of the outside diameter corresponds to the run 2 according to Figures 1 to 3. It is possible for different Run types to use the same designed barrel mounts 9.

Since usually the deviations of the actual meeting point location from the target meeting point location at Run 2 and / or walk 3 in the same direction due to manufacturing reasons will only be one relatively small number of barrel mounts 9 required, in which the distances between the axes of the Bore 14 and / or the half-shell 15 are different relative to the bores 10, 11.
