Abstract
Abstract The present invention relates to an improved enclosure apparatus for containing a shaped explosive charge which includes a top enclosure member, a bottom standoff member and a shaped liner positioned therebetween. The liner, enclosure member and standoff member each include annular flange portions and means for clamping the flange portions together are attached thereto so that a fluid tight seal between the liner, enclosure member and standoff member is provided.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
A quick assembly enclosure apparatus for a shaped explosive charge comprising: an enclosure member having an annular flange extending generally laterally of the enclosure apparatus; a standoff member having an annular flange extending generally laterally of the enclosure apparatus; a liner having an annular flange extending generally laterally of the enclosure apparatus, said liner being positioned between said enclosure and standoff members with the flange thereof disposed between the flanges of said members; sealing means disposeD between the flange of said enclosure member and the flange of said liner and between the flange of said standoff member and the flange of said liner; and, means for selectively clamping the flanges of said members together axially of the enclosure apparatus to compress said sealing means and to thereby provide a fluid tight seal.
Claim 2
Dependent Claim
132 words
A quick assembly enclosure apparatus for a shaped explosive charge comprising: an enclosure member having an annular flange extending generally laterally of the enclosure apparatus; a standoff member having an annular flange extending generally laterally of the enclosure apparatus; a liner having an annular flange extending generally laterally of the enclosure apparatus, said liner being positioned between said enclosure and standoff members with the flange thereof disposed between the flanges of said members; sealing means disposeD between the flange of said enclosure member and the flange of said liner and between the flange of said standoff member and the flange of said liner; and, means for selectively clamping the flanges of said members together axially of the enclosure apparatus to compress said sealing means and to thereby provide a fluid tight seal.
Claim 3
Dependent Claim
83 words
The apparatus of claim 1 wherein said selective clamping means includes: a generally C-shaped ring opening radially inwardly to receive the laterally extending flanges of said members; and, manually operable lever means carried by said ring, said lever means being pivotable about a point adjacent one end thereof from a first position wherein said ring may be positioned to receive said laterally extending flanges to a second position wherein said ring may be compressed together to pressurally engage the flanges of said members.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein said enclosure and standoff members are formed of a plastic material.
Claim 5
Dependent Claim
63 words
The apparatus of claim 1 wherein said sealing means comprises a generally C-shaped elastomer gasket member positioned around the outer peripheral edge of the flange of said liner with a portion thereof between the flange of said enclosure member and the flange of said liner and with a portion thereof between the flange of said liner and the flange of said standoff member.
Claim 6
Dependent Claim
13 words
The apparatus of claim 4 wherein said gasket member is formed of neoprene.
Claim 7
Dependent Claim
73 words
The apparatus of claim 1 wherein the flanges of said enclosure and standoff members each terminate in an annulet extending generally axially of the enclosure apparatus a distance not greater than about one-half the thickness of the flange of said liner, said annulets facing each other to assist in maintaining the position of said liner and said sealing means relative to said enclosure and standoff members during the assembly of the enclosure apparatus.
