Shaped charge mounting system

Claim 2

A shaped charge system comprising: an elongated panel having charge receiving apertures formed therethrough; a cylindrical-conical shaped charge structure having a mouth portion with a shoulder at a reduction to the diameter of said apertures and a circumferential groove spaced from said shoulder a distance about equal to the thickness of said panel and a transverse groove in the apex thereof; and a spring wire clip to mate in said circumferential groove for at least about 180° and having oppositely directed extensions terminating in hooks which extend above said panel and generally laterally of said transverse groove at about the level of said transverse groove to receive and position primer cord seated in said transverse groove.

Claim 3

The invention according to claim 1 wherein the diameter of the outer periphery of said clip mated in said groove is greater than said diameter of said apertures in said panel, and wherein said panel is engaged between said shoulder and said clip on opposite sides of said panel.

Claim 4

The invention according to claim 1 wherein said oppositely directed extensions of said clip extend generally radially away from said circumferential groove and along said panel, and said hooks extend away from said panel.

Claim 5

The invention according to claim 2 wherein said hooks extend generally perpendicularly away from said panel and then generally parallel to said panel at about said level of said transverse groove.

Claim 6

The invention according to claim 3 wherein said hooks bear against the top of said primer cord, and the bottom of said primer cord is seated in said transverse groove between said hooks, said primer cord being slightly deflected as it passes through said transverse groove beneath said hooks for lightly biased retention in said transverse groove.

Claim 7

A shaped charge system comprising: an elongated panel having charge receiving apertures formed therethrough; a shaped charge structure having a conical portion and an open-mouth cylindrical portion, said conical portion having a transverse groove in the apex thereof, said cylindrical portion having a reduced section adjacent said conical portion and of diameter about equal to the diameter of said apertures, said cylindrical portion having an enlarged section between said mouth and said reduced section and of diameter greater than said apertures, said enlarged section being stepped down to said reduced section by a radial shoulder such that said charge structure is insertable conical portion first into said panel aperture with a stop provided by engagement of said shoulder against said panel; and a spring wire clip mounted to said charge structure and engaging said panel on the opposite side from said shoulder to retain said charge structure in said aperture, said clip having hooks positioning a primer cord seated in said transverse groove.

Claim 8

A shaped charge system comprising: an elongated panel having charge receiving apertures formed therethrough; a shaped charge structure having a conical portion and an open-mouth cylindrical portion, said conical portion having a transverse groove in the apex thereof, said cylindrical portion having a reduced section adjacent said conical portion and of diameter about equal to the diameter of said apertures, said cylindrical portion having an enlarged section between said mouth and said reduced section and of diameter greater than said apertures, said enlarged section being stepped down to said reduced section by a radial shoulder such that said charge structure is insertable conical portion first into said panel aperture with a stop provided by engagement of said shoulder against said panel; and a spring wire clip mounted to said charge structure and engaging said panel on the opposite side from said shoulder to retain said charge structure in said aperture, said clip having hooks positioning a primer cord seated in said transverse groove.

Claim 9

The invention according to claim 6 wherein said clip has oppositely directed extensions along said panel, and said hooks extend above said panel and generally laterally of said transverse groove at about the level of said transverse groove.

Claim 10

The invention according to claim 6 wherein said clip has a substantially semicircular portion semicircumferentially engaging said panel and said charge structure, said clip having a pair of substantially opposite outward radial extensions extending longitudinally along said panel.

Claim 11

The invention according to claim 8 wherein said hooks extend away from said panel and then are bent generally laterally of said transverse groove back toward the direction of the arch of said semicircular portion.

Claim 12

A shaped charge system comprising: (A) an elongated panel having charge receiving apertures formed therethrough; (B) an integral shaped charge structure comprising: (i) a conical portion having a transverse groove in the apex thereof; and (ii) a cylindrical portion comprising: (a) a reduced section adjacent said conical portion and having a diameter substantially the same as said apertures; (b) an open mouth at the end opposite said conical portion; (c) an enlarged section between said mouth and said reduced section and of greater diameter than said apertures; (d) a radial shoulder stepping said enlarged section down to said reduced section, such that said charge structure is inserted conical portion first into said aperture with a stop provided by engagement of said shoulder against said panel; and (e) a circumferential groove formed in said reduced section and spaced from said shoulder by a distance about equal to the thickness of said panel; and (C) a spring wire clip mating in said circumferential groove for at least about 180° and having a pair of opposite extensions terminating in hooks which extend above said panel to receive and position primer cord in said transverse groove.

Claim 13

A shaped charge system comprising: (A) an elongated panel having charge receiving apertures formed therethrough; (B) an integral shaped charge structure comprising: (i) a conical portion having a transverse groove in the apex thereof; and (ii) a cylindrical portion comprising: (a) a reduced section adjacent said conical portion and having a diameter substantially the same as said apertures; (b) an open mouth at the end opposite said conical portion; (c) an enlarged section between said mouth and said reduced section and of greater diameter than said apertures; (d) a radial shoulder stepping said enlarged section down to said reduced section, such that said charge structure is inserted conical portion first into said aperture with a stop provided by engagement of said shoulder against said panel; and (e) a circumferential groove formed in said reduced section and spaced from said shoulder by a distance about equal to the thickness of said panel; and (C) a spring wire clip mating in said circumferential groove for at least about 180° and having a pair of opposite extensions terminating in hooks which extend above said panel to receive and position primer cord in said transverse groove.
