ABSTRACT:
A perforating gun contains charges which are rotatable between a stored position and a deployed position, the charges being connected to an enclosed carrier tube via a mechanical link retaining apparatus which is capable of bending but is incapable of stretching by any substantial distance. A primacord is held by said retaining apparatus firmly onto a top of each charge thereby preventing relative movement between the primacord and the charge when the charge is deploying between its stored position and its deployed position. A set of pullrods connect to each pivot of each charge. Thus, when an upward force is placed on the pullrods, an accompanying force is placed on the pivots of each charge. Since the retaining apparatus connects to the top of each charge and to the carrier, and since the retaining apparatus is incapable of stretching by any substantial distance, the accompanying force on the charge pivots creates a torque which rotates the charges between the stored position and the deployed position.
