Abstract
Abstract 1. An explosive warhead comprising, INNER AND OUTER METALLIC CYLINDERS CONCENTRICALLY DISPOSED ABOUT A COMMON AXIS, FIRST AND SECOND ANNULAR BODIES OF EXPLOSIVE MATERIAL CONCENTRICALLY DISPOSED ABOUT SAID AXIS, SAID FIRST BODY BEING DISPOSED WITHIN THE INNER CYLINDER, SAID SECOND BODY BEING POSITIONED RADIALLY BETWEEN SAID CYLINDERS IN CONTACT WITH ONE OF SAID CYLINDERS AND BEING RADIALLY SPACED FROM THE OTHER CYLINDER, AND MEANS CONNECTED TO THE FIRST BODY FOR IGNITING THE FIRST BODY OF EXPLOSIVE MATERIAL PRIOR TO THE DETONATION OF THE SECOND BODY OF EXPLOSIVE MATERIAL.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
87 words
An explosive warhead comprising, inner and outer metallic cylinders concentrically disposed about a common axis, first and second annular bodies of explosive material concentrically disposed about said axis, said first body being disposed within the inner cylinder, said second body being positioned radially between said cylinders in contact with one of said cylinders and being radially spaced from the other cylinder, and means connected to the first body for igniting the first body of explosive material prior to the detonation of the second body of explosive material.
Claim 2
Dependent Claim
87 words
An explosive warhead comprising, inner and outer metallic cylinders concentrically disposed about a common axis, first and second annular bodies of explosive material concentrically disposed about said axis, said first body being disposed within the inner cylinder, said second body being positioned radially between said cylinders in contact with one of said cylinders and being radially spaced from the other cylinder, and means connected to the first body for igniting the first body of explosive material prior to the detonation of the second body of explosive material.
Claim 3
Dependent Claim
47 words
The explosive warhead of claim 1 wherein, said outer cylinder comprises a bundle of elongated rods connected together to form an expansion-linkage type of continuous rod assembly, and said second body of explosive material is in intimate contact with the outer peripheral surface of the inner cylinder.
Claim 4
Dependent Claim
36 words
The explosive warhead of claim 2 further comprising an annular body of low density foam material positioned within and completely filling the annular space defined by said second body of explosive material and the outer cylinder.
Claim 5
Dependent Claim
41 words
The explosive warhead of claim 1 further comprising, first and second end caps disposed on opposite ends of said warhead and fixedly secured to opposite ends of said inner and outer metallIc cylinders to define a closed chamber within said warhead.
Claim 6
Dependent Claim
60 words
The explosive warhead of claim 1 wherein, said outer cylinder is a continuous metallic cylinder having a plurality of grooves formed therein to create weakened portions in the outer cylinder to facilitate fragmenting thereof upon detonation of the explosive material, and said second body of explosive material is in intimate contact with the inner peripheral surface of the outer cylinder.
Claim 7
Dependent Claim
36 words
The explosive warhead of claim 5 further comprising an annular body of low density foam material positioned within and completely filling the annular space defined by said second body of explosive material and said inner cylinder.
Claim 8
Dependent Claim
49 words
The explosive warhead of claim 1 wherein said outer cylinder is a continuous metallic cylinder having weakened portions therein to facilitate fragmenting thereof upon detonation of the explosive material, and said second body of explosive material is in intimate contact with the outer peripheral surface of the inner cylinder.
Claim 9
Dependent Claim
36 words
The explosive warhead of claim 7 further comprising an annular body of low density foam material positioned within and completely filling the annular space defined by the second body of explosive material and the outer cylinder.
Claim 10
Dependent Claim
128 words
A two stage explosive warhead comprising, a cylindrical metal tube, a first annular body of explosive material filling said tube and having a longitudinal axial bore formed therein, a second annular body of explosive material concentrically positioned about said tube and being in intimate contact with the tube throughout the periphery thereof, a plurality of rods interconnected to form an expansible-linkage type or rod assembly, said rod assembly being positioned around the second annular body of explosive material, support means for maintaining said rod assembly radially spaced apart from the second annular body of explosive material, and means mounted within said bore for initiating the first annular body of explosive material, whereby the rod assembly is radially expanded outwardly by the gases of the explosion with high velocity.
Claim 11
Dependent Claim
128 words
A two stage explosive warhead comprising, a cylindrical metal tube, a first annular body of explosive material filling said tube and having a longitudinal axial bore formed therein, a second annular body of explosive material concentrically positioned about said tube and being in intimate contact with the tube throughout the periphery thereof, a plurality of rods interconnected to form an expansible-linkage type or rod assembly, said rod assembly being positioned around the second annular body of explosive material, support means for maintaining said rod assembly radially spaced apart from the second annular body of explosive material, and means mounted within said bore for initiating the first annular body of explosive material, whereby the rod assembly is radially expanded outwardly by the gases of the explosion with high velocity.
Claim 12
Dependent Claim
47 words
The two stage explosive warhead of claim 9 further comprising an annular body of low density foam material positioned between the inner peripheral surface of the rod assembly and the outer peripheral surface of the second annular body of explosive material and completely filling the space therebetween.
