Abstract
Abstract A cartridge-type munition comprising a casing and a projectile in which the casing at least in part is constituted of combustible and destructible material. According to the invention, a first connection between the projectile and the casing is formed by a neck engaging the periphery of the projectile which is also formed with a boss or projection at its rear end engaged by radial elements forming a second connection with the casing axially spaced from the first connection.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
185 words
A cartridge-type munition round for a barrel-type weapon, comprising: a projectile having a projectile body and an extension projecting rearwardly from said body; a casing receiving said extension whereby the bulk of the projectile projects from the casing and secured to said projectile, said casing being adapted to contain a firing charge for the projectile, said casing being composed at least in part of combustible material, said casing having a forwardly converging neck at a forward end of the casing engaging said projectile around said body at a first location; and a support element within said casing surrounding and engaging said extension at a location axially spaced from said neck, said support element extending at least in part radially inwardly from said casing to said extension, said support element having generally the configuration of a disk subdividing the interior of said casing into two charge-receiving chambers and formed with at least one opening communicating between said chambers, one of said charge-receiving chambers extending between said neck and said disk around said body, said support element being composed of the same combustible material as said casing.
Claim 2
Dependent Claim
185 words
A cartridge-type munition round for a barrel-type weapon, comprising: a projectile having a projectile body and an extension projecting rearwardly from said body; a casing receiving said extension whereby the bulk of the projectile projects from the casing and secured to said projectile, said casing being adapted to contain a firing charge for the projectile, said casing being composed at least in part of combustible material, said casing having a forwardly converging neck at a forward end of the casing engaging said projectile around said body at a first location; and a support element within said casing surrounding and engaging said extension at a location axially spaced from said neck, said support element extending at least in part radially inwardly from said casing to said extension, said support element having generally the configuration of a disk subdividing the interior of said casing into two charge-receiving chambers and formed with at least one opening communicating between said chambers, one of said charge-receiving chambers extending between said neck and said disk around said body, said support element being composed of the same combustible material as said casing.
Claim 3
Dependent Claim
35 words
The cartridge-type munition round defined in claim 1 wherein said projectile is a fin-stabilized projectile and said support element bears against an inner wall of said casing and against a tail-fin assembly of said projectile.
Claim 4
Dependent Claim
55 words
The cartridge-type munition round defined in claim 2 wherein said disk is a ring having a U cross section in an axial plane of the round, said ring having an outer flange resting against an inner wall of said casing and an inner flange resting upon outer ends of the fins of the tail-fin assembly.
Claim 5
Dependent Claim
22 words

Claim 6
Dependent Claim
25 words
The cartridge-type munition round defined in claim 2 wherein said disk is formed with cutouts conforming to and accommodating the tail fins of said assembly.
Claim 7
Dependent Claim
43 words
The cartridge-type munition round defined in claim 1 wherein the disk is formed with a frustoconical portion converging forwardly and terminating in a cylindrical portion engaging said extension, said frustoconical portion having an outer cylindrical formation engaging the outer wall of said casing.
Claim 8
Dependent Claim
18 words
The cartridge-type munition round defined in claim 6 wherein said outer cylindrical formation is bonded in the casing.
Claim 9
Dependent Claim
26 words
