Abstract
Abstract A warhead fuze is attached within the warhead casing in such a manner thatressure buildup will cause the fuze mechanism to be ejected from its housing. The fuze and its associated booster is contained in a cup attached to an end cap which may be threaded to receive a closure cap. The joint between the booster cup and the end cap is made in such a manner that pressure buildup within the cup will case the joint to fail with a resultant expulsion of said booster cup away from the main explosive cavity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
In a warhead mechanism comprising a cavity containing a main charge of high explosive confined between opposing bulkheads and a container for a fuze mechanism fastened within an opening in one of said bulkheads, the improvement comprising: said container comprising an elongated cup shaped member having a closed end and an open end; said cup shaped member being fastened within said one of said bulkheads with said closed end protruding within said cavity and said open end of said cup shaped member extending from said bulkhead on the side away from said explosive; and an annular end piece joined to the open end of said cup shaped member for closure thereof; the joining of said end piece to said cup shaped member being made such that the joint will fail when a predetermined level of temperature is exceeded at said joint and a predetermined pressure is exceeded within said container.
Claim 2
Dependent Claim
150 words
In a warhead mechanism comprising a cavity containing a main charge of high explosive confined between opposing bulkheads and a container for a fuze mechanism fastened within an opening in one of said bulkheads, the improvement comprising: said container comprising an elongated cup shaped member having a closed end and an open end; said cup shaped member being fastened within said one of said bulkheads with said closed end protruding within said cavity and said open end of said cup shaped member extending from said bulkhead on the side away from said explosive; and an annular end piece joined to the open end of said cup shaped member for closure thereof; the joining of said end piece to said cup shaped member being made such that the joint will fail when a predetermined level of temperature is exceeded at said joint and a predetermined pressure is exceeded within said container.
Claim 3
Dependent Claim
16 words
The warhead mechanism of claim 1 wherein said joint consists of a one-sixteenth inch 1100°F braze.
Claim 4
Dependent Claim
54 words
The warhead mechanism of claim 2 further comprising means for fastening said cup shaped member within said one of said bulkheads comprising a collar having a central opening and peripheral means for fastening to said bulkhead and said cup shaped member being fastened within the central opening of said collar by a 1400°F braze.
Claim 5
Dependent Claim
54 words
The warhead mechanism of claim 1 further comprising means for fastening said cup shaped member within said one of said bulkheads comprising a collar having a central opening and peripheral means for fastening to said bulkhead and said cup shaped member being fastened within the central opening of said collar by a 1400°F braze.
Claim 6
Dependent Claim
16 words
The warhead mechanism of claim 4 wherein said joint consists of a one-sixteenth inch 1100°F braze.
