ABSTRACT:
In the representative embodiment of the new and improved perforating apparatus described herein, shaped charge cases are provided with matching upper and lower supports with parallel abutment surfaces and alignment means cooperatively arranged to enable a plurality of these charge cases to be stacked together for erecting an intertwined assembly of cases. By appropriately selecting the combined heights of the matching supports, adjacent ones of the charge cases can be closely spaced one above the other and directed outwardly along selected radial perforating axes at uniform angular spacings.
