Abstract
Abstract A missile of the type having a casing composed on individual segments containing movable secondary projectiles, the segments in a locked position being mutually parallel, and means for allowing a head wind striking the missile in flight to swing the segments radially outwards. Each segment contains a plurality of secondary projectiles. The segments are hingeably deflectable through an angle of approximately 170*. During the outward swing of the segments the secondary projectiles are slidably ejected from the segments by the centrifugal forces generated by the outward swing of the segments. This arrangement does without an ejecting charge for each secondary projectile and therefore saves space. In addition there is a relatively wide range of scatter of the secondary projectiles.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A missile comprising, a casing formed oF separate hinged segments, secondary projectiles contained in said segments, said segments in a locked position being mutually parallel, means for allowing a head wind striking the missile in flight to swing said segments outwards wherein the improvement resides in each of said segments containing a plurality of said secondary projectiles, said segments being hingeably deflectable through an angle of substantially 170* and said secondary projectiles being slidably ejectable from said segments during its outward swing of said segments by the centrifugal forces generated by said outward swing.
Claim 2
Dependent Claim
94 words
A missile comprising, a casing formed oF separate hinged segments, secondary projectiles contained in said segments, said segments in a locked position being mutually parallel, means for allowing a head wind striking the missile in flight to swing said segments outwards wherein the improvement resides in each of said segments containing a plurality of said secondary projectiles, said segments being hingeably deflectable through an angle of substantially 170* and said secondary projectiles being slidably ejectable from said segments during its outward swing of said segments by the centrifugal forces generated by said outward swing.
Claim 3
Dependent Claim
24 words
A missile as defined in claim 1 including guideways contained in said segments to guide said secondary projectiles and prevent them from lifting off.
Claim 4
Dependent Claim
33 words
A missile as defined in claim 2 including slots defined by said guideways, and studs mounted on said secondary projectiles which engage said slots to prevent said projectiles from lifting off said guideways.
Claim 5
Dependent Claim
57 words
A missile as defined in claim 1 wherein said means for allowing a head wind striking the missile in flight to swing said elements outwards comprises a piston operable by gas pressure and adapted to keep the segments together in their locked positions and to release the segments when displaced in the axial direction of the missile.
Claim 6
Dependent Claim
44 words
A missile as defined in claim 4 including a recessed cavity defined by said piston, and two facing surfaces of different size bounding said cavity so that gas pressure generated in said cavity will displace said piston in a direction for releasing said segments.
Claim 7
Dependent Claim
68 words
A missile as defined in claim 1 including a missile head, a rearward sleeve-like extension formed on said head and embracing the front ends of said segments, an annular chamber defined by said extension, a pyrotechnic charge contained in said chamber, and grooves defined by said extension defining lines of weakness to enable said extension to be shattered when said pyrotechnic charge explodes and to release said segments.
Claim 8
Dependent Claim
35 words
A missile as defined in claim 1 including hinges linking said segments to the missile and an axially movable ring to which all of said segments are operatively coupled for opening said segments in unison.
Claim 9
Dependent Claim
144 words
A missile comprising a casing formed of separate segments hinges linking said segments to the missile, a plurality of movable secondary projectiles conformed in each of said segments, said segments in a locked position being mutually parallel, means for allowing a head wind striking the missile in flight to swing said elements outwards, said means comprising a piston operable by gas pressure and adapted to keep the segments together in their locked positions and to release the segments when displaced in the axial direction of the missile, and an axially movable ring to which all of said segments are operatively coupled for opening said segments in unison, said segments being hingeably deflectable through an angle of substantially 170* and said secondary projectiles being slidably ejectable from said segments during its outward swing of said segments by the centrifugal forces generated by said outward swing.
Claim 10
Dependent Claim
144 words
A missile comprising a casing formed of separate segments hinges linking said segments to the missile, a plurality of movable secondary projectiles conformed in each of said segments, said segments in a locked position being mutually parallel, means for allowing a head wind striking the missile in flight to swing said elements outwards, said means comprising a piston operable by gas pressure and adapted to keep the segments together in their locked positions and to release the segments when displaced in the axial direction of the missile, and an axially movable ring to which all of said segments are operatively coupled for opening said segments in unison, said segments being hingeably deflectable through an angle of substantially 170* and said secondary projectiles being slidably ejectable from said segments during its outward swing of said segments by the centrifugal forces generated by said outward swing.
Claim 11
Dependent Claim
44 words
A missile as defined in claim 8 including a recessed cavity defined by said piston, and two facing surfaces of different size bounding said cavity so that gas pressure generated in said cavity will displace said piston in a direction for releasing said segments.
Claim 12
Dependent Claim
68 words
A missile as defined in claim 8 including a missile head, a rearward sleeve-like extension formed on said head and embracing the front ends of said segments, an annular chamber defined by said extension, a pyrotechnic charge contained in said chamber, and grooves defined by said extension defining lines of weakness to enable said extension to be shattered when said pyrotechnic charge explodes and to release said segments.
Claim 13
Dependent Claim
43 words
A missile as defined in claim 8 including guideways contained in said segments to guide said secondary projectiles, slots defined by said guideways and studs mounted on said secOndary projectiles which engage said slots to prevent said projectiles from lifting off said guideways.
