Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
Apparatus comprising a hollow charge projectile including a projectile housing, a hollow explosive charge, and a metallic lining within the housing, a tip portion secured to the housing, a retaining ring including a ring-shaped member and resilient tongue members having one end thereof joined to the ring member, the tongue members being bent out of the plane of the ring member and extending at least approximately in the peripheral direction of the ring member, and the retaining ring being arranged for securing the position of the metallic lining within the housing, the retaining ring being disposed in a groove of the tip portion of the projectile.
Claim 2
Dependent Claim
106 words
Apparatus comprising a hollow charge projectile including a projectile housing, a hollow explosive charge, and a metallic lining within the housing, a tip portion secured to the housing, a retaining ring including a ring-shaped member and resilient tongue members having one end thereof joined to the ring member, the tongue members being bent out of the plane of the ring member and extending at least approximately in the peripheral direction of the ring member, and the retaining ring being arranged for securing the position of the metallic lining within the housing, the retaining ring being disposed in a groove of the tip portion of the projectile.
Claim 3
Dependent Claim
26 words
Apparatus according to claim 1, wherein a plurality of tongue members are provided and successive tongue members are bent toward different sides of the ring member.
Claim 4
Dependent Claim
77 words
Apparatus according to claim 2, wherein the tongue members are integrally connected with the ring member, the tongue member being formed by a first radial cut extending partially through the radial extent of the ring member and by a second cut extending from the radial cut in the peripheral direction of the ring member, the formed tongue members being bent about a radial axis so as to be bent out of the plane of the ring member.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 3, wherein the ring member is a circular flat member and the second cut forming the tongue members lies substantially on a circle concentric with the periphery of the ring member.
Claim 6
Dependent Claim
29 words
Apparatus according to claim 4, wherein the tongue members are uniformly distributed about the ring member and successive tongue members are bent toward different sides of the ring member.
Claim 7
Dependent Claim
15 words
Apparatus according to claim 1, wherein the ring member is continuous and closed upon itself.
Claim 8
Dependent Claim
140 words
Apparatus comprising a hollow charge projectile including a projectile housing, a hollow explosive charge, and a metallic lining within the housing, a tip portion secured to the housing, a retaining ring including a ring-shaped member and resilient tongue members having one end thereof joined to the ring member, the tongue members being bent out of the plane of the ring member and extending at least approximately in the peripheral direction of the ring member, and the retaining ring being arranged for securing the position of the metallic lining within the housing, the retaining ring being interposed between a part of the tip portion and the metallic lining for compensating for axial variations therebetween to firmly press the metallic lining against the hollow explosive charge, the retaining ring being disposed in a recess portion of the tip portion of the projectile.
Claim 9
Dependent Claim
140 words
