Abstract

Abstract An explosive weapon and a fragmentary element therefor are disclosed. The explosive weapon comprises an explosive charge and a means to combine a plurality of fragmentary elements with the explosive charge to form an explosive assembly. Each of the fragmentary elements comprises a member having the general shape of a sphere. Each of the members has six flat surfaces located along the greatest diameter of the sphere. This greatest diameter occurs along the great circle or equatorial zone of the spherically shaped member. Each of the flat surfaces intersects the next adjacent flat surface at the greatest diameter of the sphere. Therefore, a cross section through the element in a plane including the greatest diameter and the center of the sphere has a regular hexagonal shape. The flat surfaces are adjacent elements adapted to be facially disposed to prevent rotation of the elements with respect to each other. These flat surfaces are further adapted to join other flat surfaces located in the structure of the explosive weapon. The fragmentary element has an air resistance that is only slightly greater than the air resistance of a totally spherical member of corresponding size. In more specific embodiments of the weapon, the fragmentary elements are in flat surface to flat surface contact to form rows adjacent each other. The elements of adjacent rows interlock each other to prevent shifting of the rows with respect to each other.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 175 words
An explosive weapon comprising: a. an explosive charge and b. at least one tightly sealed outer layer around the explosive charge, c. said outer layer including a plurality of fragmentary elements and means to combine said plurality of fragmentary elements with the explosive charge to form an explosive assembly, d. each said fragmentary element comprising a metal member having the general shape of a sphere, e. said member having six flat surfaces located along the greatest diameter of the sphere, f. each said flat surface intersecting the next adjacent flat surface at the greatest diameter of the sphere so that a cross section through the element in a plane including said greatest diameter and the center of the sphere has a regular hexagonal shape, g. each fragmentary element being contiguous to another fragmentary element, h. said combining means connecting the fragmentary elements only along the flat surfaces thereof, i. said flat surfaces on adjacent contiguous elements being facially disposed with respect to each other to prevent rotation of the elements with respect to each other.
Claim 2
Dependent Claim 175 words
An explosive weapon comprising: a. an explosive charge and b. at least one tightly sealed outer layer around the explosive charge, c. said outer layer including a plurality of fragmentary elements and means to combine said plurality of fragmentary elements with the explosive charge to form an explosive assembly, d. each said fragmentary element comprising a metal member having the general shape of a sphere, e. said member having six flat surfaces located along the greatest diameter of the sphere, f. each said flat surface intersecting the next adjacent flat surface at the greatest diameter of the sphere so that a cross section through the element in a plane including said greatest diameter and the center of the sphere has a regular hexagonal shape, g. each fragmentary element being contiguous to another fragmentary element, h. said combining means connecting the fragmentary elements only along the flat surfaces thereof, i. said flat surfaces on adjacent contiguous elements being facially disposed with respect to each other to prevent rotation of the elements with respect to each other.
Claim 3
Dependent Claim 31 words
An explosive weapon as defined in claim 1 wherein the structure of the weapon includes flat surfaces which are facially disposed to a flat surface located on fragmentary elements juxtaposed thereto.
Claim 4
Dependent Claim 57 words
An explosive weapon as defined in claim 1 wherein said fragmentary elements are in flat surface to surface contact to form rows of elements located adjacent to each other, the elements of adjacent rows interlock each other to prevent shifting of the rows with respect to each other, said rows of elements being juxtaposed the explosive charge.
Claim 5
Dependent Claim 21 words
An explosive weapon as defined in claim 3 wherein said combining means include adhesive material located only between adjacent flat surfaces.
Claim 6
Dependent Claim 19 words
An explosive weapon as defined in claim 3 wherein the elements are sintered together along the flat surfaces thereof.
Claim 7
Dependent Claim 28 words
An explosive weapon as defined in claim 3 wherein said rows of elements are annularly disposed around the explosive charge and are coaxial with respect to each other.
Claim 8
Dependent Claim 42 words
An explosive weapon as defined in claim 6 including a bottom portion having integral projections, said projections having a structural configuration juxtaposed the fragmentary elements of the row adjacent said bottom portion to prevent shifting between the bottom portion and fragmentary elements.
