DE3414193A1 - Push-in barrel for firearms having a large-calibre barrel for firing mostly small-calibre live cartridges - Google Patents

Abstract

The object of the invention is to make it possible, for a firearm (hunting weapon) having a mostly smooth shot barrel, to use a mostly small-calibre bullet barrel, in order to satisfy the present-day (limited) hunting possibilities with a live or delayed-action cartridge corresponding to the game or vermin to be hunted. The push-in barrel is adjusted to the barrel length of the parent weapon (shot-barrel length). It does not project and is flush with the parent weapon at the barrel nozzle. There are therefore no external visible variations or mountings, such as, for example, in German Utility Model 8000250.

Description

my plug-in barrel is based on the principle of the long-known exposed ball barrel. combined arms built, the has proven itself in practice and is being used more and more.

Like the exposed barrel, my insert barrel is in the chamber the mother weapon through the fit 3 with the edge 4 and socket firmly, but releasably mounted.

Through the plug-in barrel extractor 6, - the one in the cutout of the cartridge extractor the mother weapon is fitted, it is fixed radially.

This kind of storage of the Einstecklaufes and fixing comes almost no insert barrel manufacturer around. These are well known facts of the art.

There are only decisive differences in the setting and adjustment technology, of the exit angle. It is the same with my Einstecklauf. Here I want the support 9, the socket 19 with the plastic socket 10, which on the one hand dampens the vibrations and on the other hand emphasizes the radial bearing with axial compensation. plastic In addition, the barrel bore of the nut barrel is protected from damage when the insert barrel is pushed in.

Die'LaufJustierung is carried out by the two adjusting screws 16 for Height and side.

Adjustment screws are mostly used for adjustment. As a result of that I can fix (clamp) my adjusting screws 16 through the clamping screw 13 and slot 23, which are not affected by vibrations, Can solve vibrations etc., and that within the mother barrel, my plug-in barrel differs from the ones I know.

The barrel should swing in a controlled manner at the muzzle. If you put it through four opposing adjusting screws on the muzzle fixed, this is no longer the case, as is known from some of the plug-in barrels I know.

In contrast to my previously described insertion barrel, the adjustment takes place using the two adjusting screws 16 and, as a counter support, the Leaf spring 18 - which absorbs the vibrations resiliently - instead. A longitudinal expansion of the insert barrel is therefore also not possible Ways.

Because of this invention I get very good hit results. Kind regards

Insert barrel according to claim 2, characterized in that the insert barrel 1 is fixed in the cartridge chamber of the receiving nut barrel with the mating surfaces 3 and 4, but detachably, radially and axially. Insert barrel according to claim 3, characterized in that the insert barrel is additionally supported by the spherical socket 8 in the transition cone of the mother weapon. Insert barrel according to claim 4, characterized in that the insert barrel by the cartridge extractor 6, which is fitted into the cartridge extractor of the mother weapon by milling, against radial rotation is secured and must therefore always be inserted in the same position. Insert barrel according to claim 5, characterized in that between the Socket 8 and socket 19 a support - consisting of the plastic socket 9 - attached without being limited to this material is to avoid the large vibrations caused by the high explosion pressure of over 3000 bar with which the projectile is driven through the barrel, intercept. copy ..ζ ■ _ Owner Rudolf DueJfek WhIIrI (I Hunting clothing Need Steel goods Bamberger Straße 26 Telephone 09573/354 Sheet - / - Insert barrel according to Claim 6, characterized in that the adjusting element (Fig. II) makes up almost half of the length of the insertion barrel and thus the outlet angle adjustment or bending the Einstecklaufes 1 happens over a large length. Insert barrel according to claim 7 by the adjustment element described below marked: a) The adjusting element consists of the main parts bushing 19 and 20, as well as the connecting pipe 2 A central bore in the 0 of the insert barrel leads through the socket 19 1, thus the prerequisites for a firm connection of the insert barrel 1 and the adjustment element by soldering, Bonding or screwing given. b) A plastic bushing 10 is pressed onto this bushing 19 with a collar or glued. The socket 10 is exactly radial on the inner 0 of the nut barrel fitted. c) Longitudinal millings at 120 ° (without sketch) can be used to that the radial fit in the nut barrel. is limited to three points. d) To seal against moisture etc. there is a -19 on the socket Puncture 11 for an O-ring 12 is provided. e) The socket 20 has an eccentric bore that is aligned runs to the connecting pipe. Thus there is enough space for the adjustment of the Einstecklaufes 1. available, what by previous coarse adjustment is still supported and at the same time the adjusting screws 16 and clamping screw 13 can be attached. 1419 Jf Hermann Schein

Copy 34-193 Hermann ScheHJ lnh. Rudolf DueSek Specialty shop weapons Hunting clothing AngtertMmould SLAVWARE Bamberger Strasse 26 8623 Staffelstein Telephone 09573/354 Claim 9 characterized as follows: The radial fitting of the bush 19 into the nut barrel is time consuming. This can be achieved by means of a three-point bearing (the bush 19 is milled free on 3 points by longitudinal milling at 120 °) can be reached more easily. In this case the 3rd point is prepared for a spring. The spring radially encloses the plug-in barrel 1 in the vicinity of the socket 19 and is resiliently located in a corresponding longitudinal groove on the bush 19 and is thus secured radially and axially at the same time. The radial and axial fastening can also be achieved by means of a screw happen. A leaf spring or a spring made of round steel can be used. The spring always presses the bushing 19 and thus the adjusting element evenly at 2 points (spring is 3rd point) against the nut barrel. Since the holes of the mother weapon have strong tolerances in 0, the spring compensates for this difference. Copy
