Abstract
The present invention relates to a pipeline plugger for mounting on a pipe which pipe has an insertion port. The pipeline plugger includes a housing adapted for mounting on the pipe adjacent to the insertion port. A rod is mounted in the housing and is axially movably transverse to the axis of the pipe. The rod has a carrier block connected to one end. A holding pin is mounted on the carrier block substantially opposed to the rod. The pipe has a pin aperture substantially opposite to the insertion port. The pin aperture is adapted to receive the pin. A plug is pivotally connected to the carrier block. The plug is adapted to be selectively positioned in the pipe to stop the flow of fluid through the pipe past the plug.
