Abstract
Abstract A segmented ejectable payload container is arranged to provide improved protection against axial separation of its segments during the firing operation. The container is formed as a hollow shell, with its outer jacket formed integral with a bottom end plate whose outer surface is recessed to receive an outwardly extending flange of an inner container jacket. The other end of the opposed jackets is removably closed by means of a threaded end plate. A second flange on the inner jacket is received in a corresponding recess of the second end plate when such end plate is in operative position. The interfaces between the flanges on the inner jackets and the recesses in the respective end plates are closed by means of a radially disposed seal. The depth of such recesses is chosen so that the outer surface of each end plate projects beyond the adjacent surface of the associated flange.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
237 words
In an ejectable payload for a ballistic projectile, the payload comprising incendiary material arranged along and coaxially around a central ignition channel of the projectile and disposed within a plurality of hollow annular elongated containers, the containers being successively disposed axially in abutting relation between a front nose portion and a rear tail portion of the projectile, the inner boundary of each container including at least one apertuer extending radially therethrough for providing communication between the interior of the ignition channel and the incendiary material within the associated container, an improved construction for the container which comprises, in combination, an axially extending outer cylindrical jacket, a first radially disposed end plate integral with and extending inwardly from a lower end of the outer jacket, the inner portion of the first end plate having a first recess in its outer surface, an axially extending inner cylindrical jacket having first and second flanges extending radially outwardly from its upper and lower ends, respectively, a second radially disposed end plate, the inner portion of the second end plate having a second recess in its outer surface, and means for removably and threadedly connecting the second end plate to the upper end of the outer jacket, the first and second flanges of the inner jacket being received tightly within the first and second recesses of the respective end plates when the second end plate and the outer jacket are threadedly connected.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
67 words
The construction as defined in claim 1, in which the connecting means comprises, in combination, means defining a third recess on the outer surface of the outer jacket at the upper end thereof, and a third flange extending downwardly and axially from the outer surface of the second end plate, the outersurface of the third recess and the inner surface of the third flange having mating threads.
Claim 4
Dependent Claim
43 words
The construction as defined in claim 2, in which the outer surface of the third flange is disposed in axial alignment with the outer surface of the outer jacket below the third recess when the third flange is threaded into the third recess.
Claim 5
Dependent Claim
63 words
The construction as defined in claim 1, in which the inner jacket comprises inner and outer portions disposed in radially abutting relation, in which the first and second flanges extend radially outwardly from the respective ends of the inner portion, and in which the respective ends of the outer portion terminate within and in axially spaced relation to the first and second flanges.
Claim 6
Dependent Claim
39 words
The construction as defined in claim 4, in which the length of the outer portion corresponds substantially to the distance between the upper end of the outer jacket and the inner surface of the first end plate integral therewith.
Claim 7
Dependent Claim
31 words
The construction as defined in claim 1, further comprising first radially disposed sealing means situated intermediate the inner surface of the first flange and the outer surface of the first recess.
Claim 8
Dependent Claim
31 words
The construction as defined in claim 1, further comprising second axially disposed sealing means disposed intermediate the outer surface of the third recess and the inner surface of the third flange.
Claim 9
Dependent Claim
55 words
The construction as defined in claim 1, in which the depth of the first recess is greater than the thickness of the first flange so that the outer surface of the first end plate projects axially outwardly from the outer surface of the first flange when the first flange is received in the first recess.
Claim 10
Dependent Claim
55 words
A construction as defined in claim 1, in which the depth of the second recess is greater than the thickness of the second flange so that the outer surface of the second end plate projects axially outwardly from the outer surface of the second flange when the second flange is received in the second recess.
