Abstract
Abstract An explosive shrapnel shell has a bursting charge having a front end, a layer of shrapnel laterally surrounding the charge except at the end, a fuse mounted on the front end, and shrapnel in the fuse. The fuse includes a detonator charge lying between the fuse shrapnel and the bursting charge. The shell is generally centered on an axis extending through the front end and the fuse includes an axially rearwardly extending tube. The detonator charge is in and axially behind the tube and the fuse shrapnel form a ring circumferentially surrounding the tube. An intensifying charge can lie between the detonator charge and the bursting charge.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
An improved shrapnel shell having an interior wall, an ignition fuse, and an outer shrapnel multilayer which layer laterally surrounds a bursting charge, the improvement comprising (a) said ignition fuse forming the nose of the shell and having a cylindrical rearwardly axially extending portion having an outer cylindrical wall containing second shrapnel which portion defines a first annular space between its outer cylindrical wall and the interior wall of the shell; (b) said bursting charge disposed in said shell and extending into said first annular space; (c) a coaxial detonating charge extending through at least a portion of said cylindrical portion defining a second annular space containing the second shrapnel; and (d) an intensifying charge mounted in said cylindrical portion and having a higher specific energy that said bursting charge and being disposed behind said tube and said second shrapnel and extending across the entire cross-section of said cylindrical portion.
Claim 2
Dependent Claim
150 words
An improved shrapnel shell having an interior wall, an ignition fuse, and an outer shrapnel multilayer which layer laterally surrounds a bursting charge, the improvement comprising (a) said ignition fuse forming the nose of the shell and having a cylindrical rearwardly axially extending portion having an outer cylindrical wall containing second shrapnel which portion defines a first annular space between its outer cylindrical wall and the interior wall of the shell; (b) said bursting charge disposed in said shell and extending into said first annular space; (c) a coaxial detonating charge extending through at least a portion of said cylindrical portion defining a second annular space containing the second shrapnel; and (d) an intensifying charge mounted in said cylindrical portion and having a higher specific energy that said bursting charge and being disposed behind said tube and said second shrapnel and extending across the entire cross-section of said cylindrical portion.
Claim 3
Dependent Claim
22 words
The explosive shrapnel shell defined in claim 1, wherein said intensifying charge is disposed between the detonator charge and the bursting charge.
Claim 4
Dependent Claim
18 words
The explosive shrapnel shell defined in claim 1 wherein the second fuse shrapnel is a multiplicity of balls.
Claim 5
Dependent Claim
16 words
The explosive shrapnel shell defined in claim 3 wherein the balls are of a heavy metal.
Claim 6
Dependent Claim
14 words
The explosive shrapnel shell defined in claim 4 wherein the heavy metal is tungsten.
Claim 7
Dependent Claim
26 words
The explosive shrapnel shell defined in claim 1 wherein the second fuse shrapnel is imbedded and carried in an at least limitedly flexible synthetic-resin support body.
Claim 8
Dependent Claim
23 words
The explosive shrapnel shell defined in claim 1 wherein the fuse includes a safety lying between the fuse shrapnel and the bursting charge.
