Patent ID: 7493961

Claim:
A shaped charge carrier joint comprising the assembly combination of a pair of axially elongated inner loading tubes disposed within a pair of axially elongated external housing tubes, each external housing tube having an external screw thread proximate of a first distal end and a predetermined length of first outside diameter proximate of a second distal end thereof, said housing tube having an outside second diameter between said screw thread and said predetermined length that is greater than said first outside diameter, a circumferential detent channel penetrating a surface of said predetermined length, a snap ring confined within said detent channel and having an outside third diameter greater than said first diameter but less than said second diameter, an axially slidable sleeve overlying said snap ring and a portion of said predetermined length, said sleeve having an outside fourth diameter approximately the same as said second diameter and an inside fifth diameter greater than said third diameter, said sleeve further having at a first distal end an internal screw thread corresponding to said housing tube external screw thread and proximate of an opposite distal end, an annular abutment shoulder having an inside sixth diameter greater than said first diameter and less than said third diameter and means between the first distal end of a first housing tube and the second distal end of a second housing tube for setting and securing a predetermined angular position of said housing tubes about the housing tube axes when said internal sleeve thread is meshed with said external housing thread.
