Abstract

Abstract A projectile housing. A body of pyrotechnic material in the housing. A fuze container fixed to the base end of the housing. A burning fuze material in the fuze container, the container fabricated of a material that looses its structural integrity in response to the heat of the fuze flame front, whereby upon impact of the projectile that container separates exposing the burning fuze to the body of pyrotechnic material.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 116 words
A projectile, comprising: a. a housing having a forward end and a base end, b. a main charge of ignitable material in said housing, c. a container fixed to said housing, d. a fusing material located within said container and normally separated from contact with said main charge, e. means for igniting said fusing material prior to impact of the projectile thereby generating a traveling flame front, and f. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact of said housing a portion of said container separates from the remainder thereof whereupon the separated portion and the fusing material comes into contact with said main charge.
Claim 2
Dependent Claim 116 words
A projectile, comprising: a. a housing having a forward end and a base end, b. a main charge of ignitable material in said housing, c. a container fixed to said housing, d. a fusing material located within said container and normally separated from contact with said main charge, e. means for igniting said fusing material prior to impact of the projectile thereby generating a traveling flame front, and f. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact of said housing a portion of said container separates from the remainder thereof whereupon the separated portion and the fusing material comes into contact with said main charge.
Claim 3
Dependent Claim 18 words
The projectile according to claim 1, wherein said container is fixed to said base end of said housing.
Claim 4
Dependent Claim 12 words
The projectile according to claim 1, wherein said container is substantially tubular.
Claim 5
Dependent Claim 26 words
The projectile according to claim 3, further comprising a tubular insulating and support sleeve fixed to said housing and in surrounding spaced relation to said container.
Claim 6
Dependent Claim 16 words
The projectile according to claim 4, wherein said sleeve contains a plurality of longitudinally extending slots.
Claim 7
Dependent Claim 24 words
The projectile according to claim 1, further comprising additional containers each mutually interconnected with said first mentioned container by means of a central hub.
Claim 8
Dependent Claim 34 words
The projectile according to claim 1, wherein: g. said main charge substantially fills said housing, and has a throughbore extending therethrough and wherein, h. said container is substantially tubular and located within said throughbore.
Claim 9
Dependent Claim 18 words
The projectile according to claim 7 wherein said container is affixed to the base end of said housing.
Claim 10
Dependent Claim 24 words
The projectile according to claim 8, further comprising a sleeve extending from said base end into said throughbore in surrounding relation to said container.
Claim 11
Dependent Claim 15 words
The projectile according to claim 9, wherein said sleeve has a plurality of longitudinal slots.
Claim 12
Dependent Claim 131 words
A projectile comprising: a. a housing having a forward end and a base end, b. a main charge of ignitable material located in said housing, c. a container in said housing fixed to said base end, d. a fusing material located within said container and normally separated from said main charge, e. means for igniting said fusing material prior to impact of the projectile to generate a flame front which travels in a direction from said base end to said forward end of said housing, and f. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact of said forward end of said housing the forward portion of said container separates from the base portion thereof and travels into said main charge.
Claim 13
Dependent Claim 131 words
A projectile comprising: a. a housing having a forward end and a base end, b. a main charge of ignitable material located in said housing, c. a container in said housing fixed to said base end, d. a fusing material located within said container and normally separated from said main charge, e. means for igniting said fusing material prior to impact of the projectile to generate a flame front which travels in a direction from said base end to said forward end of said housing, and f. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact of said forward end of said housing the forward portion of said container separates from the base portion thereof and travels into said main charge.
Claim 14
Dependent Claim 43 words
The apparatus according to claim 11, wherein; g. said container is substantially tubular and there is further provided; h. a sleeve surrounding said container, and i. first fire and output Mixes located respectively at the base end and forward end of said container.
Claim 15
Dependent Claim 18 words
The apparatus according to claim 12, wherein said container is located in a throughbore in said main charge.
Claim 16
Dependent Claim 67 words
A projectile fuze, comprising; a. a container b. a body of fusing material located in said container, c. means for igniting said fusing material prior to impact of the projectile for generating a traveling flame front, and d. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact a portion of said container separates from the remainder thereof.
Claim 17
Dependent Claim 67 words
A projectile fuze, comprising; a. a container b. a body of fusing material located in said container, c. means for igniting said fusing material prior to impact of the projectile for generating a traveling flame front, and d. said container being fabricated of a material which is sufficiently weakened by said flame front such that upon impact a portion of said container separates from the remainder thereof.
Claim 18
Dependent Claim 17 words
The fuze according to claim 14, further comprising: e. insulating means in surrounding relation to said container.
Claim 19
Dependent Claim 31 words
The fuze according to claim 14, further comprising; e. a first fire mix at one end of said container, and f. an output mix at the other end of said container.
Claim 20
Dependent Claim 13 words
The fuze according to claim 14, wherein; e. said container is substantially tubular.
Claim 21
Dependent Claim 20 words
The fuze according to claim 17, further comprising; f. a tubular insulating sleeve in surrounding spaced relation to said container.
Claim 22
Dependent Claim 17 words
The fuze according to claim 18, wherein; g. said sleeve contains a plurality of longitudinally extending slots.
Claim 23
Dependent Claim 31 words
The fuze according to claim 19, further comprising; h. a first fire mix at one end of said container, and i. an output mix at the other end of said container.
Claim 24
Dependent Claim 25 words
The fuze according to claim 14, further comprising; e. additional containers, each mutually interconnected with said first mentioned container by means of a central hub.
