  • Patent number: 4388969
    Abstract: A side entry apparatus for use in a drill string permits a wireline to be connected with tool apparatus within the pipe and passed to the exterior of the pipe intermediate the ends of the drill string so that sections of pipe may be added to the drill string without interrupting the connection and resulting communication between the wireline and tool apparatus to which it is connected. The side entry apparatus includes a housing having an opening through the wall of the housing. A sealing element is arranged to be positioned about the wireline, between the wireline and the opening. A jacking mechanism is used to compress the sealing element and thereby move it into sealing contact about the wireline.
