Summary:A split wedge/breechblock (14, 10) for inserting and extracting the bridge seal (17) from the powder chamber of a gun tube. The device includes a sealing mechanism for the sliding surfaces between the wedge (14) and the breechblock (10), a bridge seal (17) for use in the XM 297 gun system, and an improved stepped wedge and breechblock design which eliminates adverse downward forces during gun firing. La présente invention concerne un ensemble à coin de culasse et bloc-culasse séparés (14, 10) permettant d'insérer et d'extraire la cloison d'obturation (17) de la chambre à poudre du fût d'un canon. Le dispositif est constitué d'un mécanisme d'étanchéité pour les surfaces de glissement entre le coin de culasse (14) et le bloc-culasse (10) et d'une étanchéité de cloison (17) utilisable sur le système d'artillerie XM 297. En outre, l'amélioration de la structure en marches d'escalier entre le coin de culasse et le bloc-culasse annule les forces s'exerçant malencontreusement vers le bas pendant le tir du canon.
