Case jacket made of combustible fibrous material with specific dimensions
A recently granted patent (Publication Number: US11898833B2) discloses a case jacket made of felted, combustible fibrous material designed for use in ammunition assemblies. The case jacket comprises a cylindrical portion, a calotte-shaped bottom, and a conical connecting portion. The cylindrical portion has specific inside and outside diameters, with the calotte-shaped bottom featuring an annular connecting edge with smaller diameters. The conical connecting portion connects the cylindrical portion to the calotte-shaped bottom, with both inner and outer walls inclined at angles not exceeding 10 degrees relative to the cylinder axis. The patent further details variations in wall thickness, the presence of embedded textile fabric, and specific assembly configurations.
The patent claims also outline variations in the angles of inclination of the inner and outer walls, with some embodiments limiting these angles to 3 or 7 degrees. Additionally, the calotte-shaped case bottom is described to have a cylindrical portion facing the cylindrical case jacket, with specific wall thickness configurations maintained throughout the case jacket. The patent also covers the embedding of textile fabric within the cylindrical case jacket portion. Furthermore, the patent extends to an ammunition assembly incorporating the described case jacket, where the coupling with the bottom is detailed to ensure specific positioning of the calotte-shaped case bottom within the cavity defined by the bottom. The conical connecting portion is designed to reside outside the cavity, with precise angles of inclination specified for the connecting wall. Overall, the patent provides detailed technical specifications for the construction and assembly of the case jacket and its application in ammunition assemblies.
