Abstract
Abstract A consumable explosive cartridge includes an explosive charge defining therewithin a recess. A primer material is disposed within the recess and is of less volume than the volume of the recess to resist premature detonation of the cartridge. A method for making the cartridge includes the steps of providing a pair of cartridge half sections, each containing an explosive charge and a recess section. A primer material is inserted within one of the recesses and the half sections are secured together with the primer material being disposed within a recess formed by the recess sections.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
15 words
A consumable explosive cartridge according to claim 1 wherein said jacket is comprised of nitrocellulose.
Claim 2
Dependent Claim
39 words
A consumable explosive cartridge according to claim 2 wherein said outer jacket is comprised of flexible nitrocellulose; said charge of explosive material being in loose granular form; and said recess being defined by wall means comprised of flexible nitrocellulose.
Claim 3
Dependent Claim
31 words
A consumable explosive cartridge according to claim 3 wherein said outer jacket is substantially spherical; and said recess-defining wall means comprising a shell located centrally within said charge for omni-directional detonation.
Claim 4
Dependent Claim
67 words
A consumable explosive cartridge in accordance with claim 4 wherein said jacket comprises a pair of semi-spherical jacket sections, each section defining an opening; a wall of nitrocellulose being disposed transversely across each opening to define a charge-containing chamber; each wall including a central indentation; said sections being bonded together, with said walls and their respective indentations being disposed in facing relationship to define a shell-containing housing.
Claim 5
Dependent Claim
46 words
A consumable explosive cartridge in accordance with claim 3 wherein said outer jacket is substantially spherical; said recess-defining wall means comprising a shell disposed centrally within said charge; said shell being sufficiently brittle to produce, upon collapse, abrasive fragments for contacting and detonating said primer material.
Claim 6
Dependent Claim
79 words
A consumable explosive cartridge for use in a firearm having a percussive detonation element, said cartridge comprising a spherical outer jacket of consumable material; a carge of explosive material contained within said outer jacket; a spherical primer-containing recess disposed centrally within said explosive material so as to be spaced uniformly inwardly from said jacket and surrounded by said explosive material on all sides; pressure-sensitive primer material disposed within said central recess for omni-directional detonation by the percussive detonation element.
Claim 7
Dependent Claim
46 words
A consumable explosive cartridge according to claim 7 wherein said outer jacket is flexible; said charge being in loose granular form; and said recess being of larger volume than said primer material, which is freely displaceable therein so as to resist unintentional detonation by external forces.
Claim 8
Dependent Claim
20 words
A consumable explosive cartridge according to claim 8 wherein said recess is defined by flexible wall means of consumable material.
Claim 9
Dependent Claim
26 words
A consumable explosive cartridge according to claim 9 wherein said jacket and said wall means comprise flexible nitrocellulose; and said primer material being in pellet form.
Claim 10
Dependent Claim
70 words
A consumable explosive cartridge according to claim 10 wherein said wall means comprises a flexible shell; said jacket comprising semi-spherical jacket sections, each section defining an opening; a wall of nitrocellulose being disposed transversely across each opening to define a charge-containing chamber; each wall including a central indentation; said sections being bonded together, with said walls and their respective indentations being disposed in facing relationship to define a shell-containing housing.
