An apparatus for removing a dud (4) is disclosed, which makes it possible to safely remove a dud (4) from various kinds of guns used as long-range firepower when a shell is caught in the inner diameter of a gun barrel and thus is not discharged. The apparatus includes a forward driving means (10) providing a propulsive force for forwarding the apparatus along an inner surface of a gun barrel, a press driving part (20) directly connected to the forward driving means (10) and having a built-in motor (21) to provide a rotating force, a sticking means (30) connected to the press driving part (20) and extended to an outside to be tightly stuck on the inner surface of the gun barrel by a main shaft (25) being rotated by the motor (21), and a pushing part (40) having one end part connected to the sticking means (30) and the other end part coupled to a cap (40b) that is in contact with the dud, and pushing the cap (40b) through a forward movement of the main shaft (25) after the sticking on the inner surface of the gun barrel is performed by the sticking means (30).

L'Invention concerne un système de chargement d'une munition, telle qu'une munition télescopée, dans une chambre pivotante (1) d'une arme, en particulier d'une arme de moyen calibre. Le système comprend un dispositif d'alimentation (A;A1) qui est solidaire de la masse oscillante (MO) de l'arme, est latéralement décalé par rapport au tube (2) de l'arme et est situé entre l'axe de tourillonnement (X-X) de l'arme et la chambre pivotante (1), et un dispositif d'introduction (I) d'une munition (200) dans la chambre (1) qui est lsolidaire de la masse reculante (MR) de l'arme, est situé au-dessus du tube (2) et est sensiblement dans le plan vertical de pivotement de la chambre (1), la munition étant acheminée du dispositif d'alimentation (A1) au dispositif d'introduction (I) par une étoile d'alimentation (40) montée en rotation autour du tube (2) de l'arme.

Eine Schußwaffe (1) weist eine den Laderaum (5) bildende Abschußkammer (4) auf, die in einem waffengehäusefesten Abschußblock (6) quer zur Laufrichtung zwischen einer Feuerstellung und einer Ladestellung hin- und herbewegbar ist. Der Laderaum (5) schließt dabei in der Ladestellung frei zugänglich einerends durch eine Ladeöffnung (7) an einen Magazinansatz (8) und andernends durch eine Auswurföffnung (9) an einen Auswurfschacht (10) an. Zum Laden und Entladen trägt ein in Laufrichtung längsveschiebbar geführtes Gleitstück (14) einen Zubringer (16), der aus einer hinter dem Magazinansatz (8) liegenden Ausgangslage über den Magazinansatz (8) hinweg bis in die Ladeöffnung (7) vorschiebbar ist.

Um einen funktionssicheren, störunanfälligen Entladevorgang zu erreichen, weist der Abschußblock (6) im der Feuerstellung der Abschußkammer (4) zugewandten Randbereich (9a) der Auswurf­öffnung (9) eine mit Abstand von der Innenkante (9b) ange­ordnete Auswurfnase (20) auf, die in eine sich zur Innenkante (9b) der Auswurföffnung (9) hin erstreckende, muldenförmig verlaufende Leitfläche (21) übergeht, und ist die Abschuß­kammerbewegung von der Ladestellung in die Feuerstellung auslösbar, bevor der Zubringer (16) seine ladeöffnungsseitige Endlage erreicht.

A riot control weapon comprises a barrel, a fixed breech block, and there-between a chamber having a loading aperture through which a cylindrical round of ammunition can be inserted and ejected, the round being insertable by firstly a translational movement to bring the forward end of the round into the chamber, and secondly a rotational movement during which the round is pivoted until the round is fully chambered in alignment with the barrel, and wherein the chamber is provided with an obturating surface which extends continuously from a point adjacent the forward end of the chamber adjacent the loading aperture, rearwardly and away from the loading aperture to complete a closed loop within a cylindrical surface internally of the chamber, whereby the said rotational movement brings the round into sealing contact with the obturating surface around a complete loop.

In a preferred embodiment there is provided a stop adjacent the forward end of the chamber, the round coming into contact with the stop at the end of the said translational movement, and the stop acting as a pivotal point for the said rotational movement.

An externally powered twin-barrel machine gun includes a shuttle (42) having two firing chambers (64), 66). The shuttle linearly moves between two positions so that the firing chambers are alternately fed a round of ammunition and discharged. A feed system (21) has a pair of augers (23, 24) each with a helical groove (26) therein which receives a round of ammunition which obtains a dwell position on a zero pitched section (28) of the grooves. A ramming system (91) rams a round of ammunition to the firing chamber aligned therewith and simultaneously ejects any spent cartridge through a forward aperture (62) in the housing (16). The spent cartridge is frictionally engaged by an axially aligned acceleration belt (76) which quickly withdraws the spent cartridge from the firing chamber and accelerates it onto a deflection cam (88).
