Method of connecting substantial similar metal parts

Claim 1

In the manufacture of a bomblet of generally spherical shape, wherein said bomblet has a casing comprising a first metal hemisphere and a second metal hemisphere which are substantially similar, the method permanently and reliably connecting said first metal hemisphere and a second substantially similar metal hemisphere, wherein each said hemisphere has a free and open end, an internal surface, an external surface, and an axis, and wherein said connecting is to be free end-to-free end, comprising the steps of: a. forming a male type configuration on the external surface of the free and open end of said first metal hemisphere, wherein said male configuration includes a flange, a groove, and a shoulder; b. forming a complementary female type configuration on the internal surface of the free and open end of said second substantially similar metal hemisphere, wherein said female complementary configuration includes a flange, a groove, and a shoulder; c. flaring said female configurated and open end of said second metal hemisphere to accept the male configurated free and open end of said first metal hemisphere; d. positioning said first metal hemisphere and said second substantially similar metal hemisphere so that said metal hemispheres are disposed free end-to-free end, and also so that said metal hemispheres are axially aligned; e. filling said first and said second metal hemispheres with a suitable explosive; f. inserting the male configurated free and open end of said first metal hemisphere into the flared female configurated free and open end of said second metal hemisphere, while maintaining axial alignment of said metal hemispheres, whereby said free ends of said metal hemispheres are releasably engaged; g. and, squeezing the flared female configurated end of said second metal hemisphere, whereby said female configurated end of said second metal hemisphere and the male configuratEd end of said first metal hemisphere are mated; whereby a positive, permanent, and interlocking joint is formed without pinching the explosive within said first and said second metal hemispheres, and whereby said first metal hemisphere and said second metal hemisphere are connected permanentaly and reliably and without the danger of said explosive detonating.
