Abstract
Abstract A projectile having a first plurality of flechettes arranged to be disper during the flight of the projectile by an explosive removal of a surrounding portion of the projectile casing and a second plurality of flechettes adapted to be subsequently dispersed by a movement thereof forwardly through a rear portion of the casing of the projectile and subsequent lateral displacement therefrom.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
92 words
Projectile means comprising: a casing having a nose, a front portion defining a front bay, and a rear portion defining a rear bay; a first plurality of flechettes in said front bay; a second plurality of flechettes in said rear bay; means for separating said front portion from the projectile in flight to expose said front bay and free said first plurality of flechettes for flight independently of said casing; and means for ejecting said second plurality of flechettes forwardly and outwardly from said second bay for flight independently of said casing.
Claim 2
Dependent Claim
92 words
Projectile means comprising: a casing having a nose, a front portion defining a front bay, and a rear portion defining a rear bay; a first plurality of flechettes in said front bay; a second plurality of flechettes in said rear bay; means for separating said front portion from the projectile in flight to expose said front bay and free said first plurality of flechettes for flight independently of said casing; and means for ejecting said second plurality of flechettes forwardly and outwardly from said second bay for flight independently of said casing.
Claim 3
Dependent Claim
72 words
The projectile means of claim 1 including means for imparting a spin to the projectile about the longitudinal axis thereof as an incident to the firing thereof and means for carrying said first plurality of flechettes in said front bay arranged to release said first plurality for radially outward movement as a result of the centrifugal force developed therein by said spin upon separation of said front casing portion from the projectile.
Claim 4
Dependent Claim
23 words
The projectile means of claim 1 wherein said separating means comprises means for splitting said front casing portion into a plurality of sections.
Claim 5
Dependent Claim
31 words
The projectile means of claim 1 wherein said separating means includes explosive means for deforming said front casing portion radially outwardly while allowing said rear casing portion to remain substantially intact.
Claim 6
Dependent Claim
39 words
The projectile means of claim 1 wherein said ejecting means comprises propellant means and means for causing said propellant means to eject said second plurality of flechettes subsequent to the separating of the front casing portion from the projectile.
Claim 7
Dependent Claim
77 words
The projectile means of claim 1 including means for imparting a spin to the projectile about the longitudinal axis thereof as an incident to the firing thereof and means for carrying said second plurality of flechettes in said rear bay arranged to release said second plurality for radially outward movement as a result of the centrifugal force developed therein by said spin upon ejection of said second plurality of flechettes to forwardly of said rear casing portion.
Claim 8
Dependent Claim
21 words
The projectile means of claim 1 including means for mounting said flechettes in a plurality of tiers in said rear bay.
Claim 9
Dependent Claim
33 words
The projectile means of claim 1 including means for mounting said flechettes in a plurality of tiers in said rear bay and said ejecting means ejects said tiers successively from said rear bay.
Claim 10
Dependent Claim
38 words
The projectile means of claim 1 wherein each of said separating and ejecting means comprises explosive means, and means are provided for igniting the ejecting explosive means as an incident of the igniting of the separating explosive means.
Claim 11
Dependent Claim
34 words
The projectile means of claim 1 wherein said ejecting means includes propellant means rearwardly of said rear bay and means extending longitudinally of the projectile through said rear bay for actuating said propellant means.
Claim 12
Dependent Claim
48 words
The projectile means of claim 1 including means for mounting said flechettes in a plurality of tiers in said rear bay, said ejecting means includes propellant means rearwardly of said rear bay and means extending longitudinally of the projectile through said mounting means for actuating said propellant means.
Claim 13
Dependent Claim
30 words
The projectile means of claim 11 wherein said mounting means defines a segmented flash tube arranged to form a plurality of separate fragments upon ejection thereof from said rear bay.
Claim 14
Dependent Claim
54 words
The projectile means of claim 1 including means for mounting said flechettes in a plurality of tiers in said rear bay, said mounting means comprising a plurality of separable sections interlocked in assembled relationship in said rear bay and arranged to form a plurality of separate fragments upon ejection thereof from said rear bay.
Claim 15
Dependent Claim
19 words
The projectile means of claim 1 including threaded means connecting said front casing portion to said rear casing portion.
Claim 16
Dependent Claim
25 words
The projectile means of claim 1 including means for visually indicating substantially the time of separating of said first plurality of flechettes from the projectile.
Claim 17
Dependent Claim
21 words
The projectile means of claim 1 including means for visually indicating the trajectory of the casing nose subsequent to said ejection.
Claim 18
Dependent Claim
22 words
The projectile means of claim 1 wherein said separating means comprises means for splitting said front casing portion longitudinally of the projectile.
Claim 19
Dependent Claim
33 words
The projectile means of claim 1 wherein said ejecting means includes a pusher movable forwardly through said rear bay and arranged to form a separate fragment upon ejection thereof from said rear bay.
Claim 20
Dependent Claim
54 words
The projectile means of claim 1 wherein said separating means comprises explosive means and said ejecting means comprises ignitable propellant means, and further including fuse means for igniting said explosive means, and means for igniting said propellant means selectively by said fuse means or as an incident of the igniting of said explosive means.
Claim 21
Dependent Claim
87 words
The projectile means of claim 1 wherein said separating means comprises explosive means and said ejecting means comprises ignitable propellant means, and further including fuse means for igniting said explosive means, means for igniting said propellant means by the fuse means, and passage means communicating between said explosive means and said propellant means for igniting said propellant means as an incident of the igniting of said explosive means in the event said means for igniting said propellant means by the fuse fails to ignite said propellant means.
