Total Claims: 10
Claim 1
Independent Claim
214 words
An improved point-detonating, variable time-delayed fuze for projectiles, which fuze comprises, in combination: a. a fuze body; b. a readily crushable nose disposed at the front end of said body; c. a thermal initiator disposed in said nose, said initiator including i. a cup having a closed front end and an open rear end closed by a non-metallic, thermally destructive closure; and, ii. a readily thermally ignitable, incendiary, exothermic chemical material disposed in said cup; d. a rotor ball disposed in said body rearwardly of and and adjacent to said initiator; e. a thermally ignitable flash detonator disposed in said rotor ball, said detonator including i. a cup having a closed thermal barrier end and an opposite end closed by a disk, ii. an insulating barrier material in said cup adjacent to said closed thermal barrier end, and iii. a primary explosive material in said cup adjacent to said insulating thermal barrier; f. a main charge of booster explosive disposed in the rear end of said fuze body adjacent said rotor ball; and, g. biasing means connected to said rotor ball for maintaining said detonator out of alignment with said initiator and main booster explosive charge except during rapid rotation of said fuze upon firing of a projectile to which said fuze is attachable.
Claim 2
Dependent Claim
214 words
An improved point-detonating, variable time-delayed fuze for projectiles, which fuze comprises, in combination: a. a fuze body; b. a readily crushable nose disposed at the front end of said body; c. a thermal initiator disposed in said nose, said initiator including i. a cup having a closed front end and an open rear end closed by a non-metallic, thermally destructive closure; and, ii. a readily thermally ignitable, incendiary, exothermic chemical material disposed in said cup; d. a rotor ball disposed in said body rearwardly of and and adjacent to said initiator; e. a thermally ignitable flash detonator disposed in said rotor ball, said detonator including i. a cup having a closed thermal barrier end and an opposite end closed by a disk, ii. an insulating barrier material in said cup adjacent to said closed thermal barrier end, and iii. a primary explosive material in said cup adjacent to said insulating thermal barrier; f. a main charge of booster explosive disposed in the rear end of said fuze body adjacent said rotor ball; and, g. biasing means connected to said rotor ball for maintaining said detonator out of alignment with said initiator and main booster explosive charge except during rapid rotation of said fuze upon firing of a projectile to which said fuze is attachable.
Claim 3
Dependent Claim
24 words
The improved fuze of claim 1 wherein said rotor ball is metallic and substantially spherical and wherein said biasing means comprises a C-shaped spring.
Claim 4
Dependent Claim
35 words
The improved fuze of claim 1 wherein said detonator cup includes a layer of thermally insulative material disposed between said closed cup end and said primary explosive to regulate the time delay for said fuze.
Claim 5
Dependent Claim
23 words
The improved fuze of claim 1 wherein said initiator composition is of a preselected density to regulate the time delay for said fuze.
Claim 6
Dependent Claim

Claim 9
Dependent Claim
26 words
The improved fuze of claim 7 wherein said initiator cup is metal and said cup closure is selected from the group consisting of plastic and paper.
Claim 10
Dependent Claim
22 words
The improved fuze of claim 8 wherein said exothermic chemical material comprises a mixture of powdered metallic fuel, an oxidizer, and additives.
