Patent number: 6719479Abstract: A breech lock wireline connector for connecting tools to a wireline inserted into a well bore. The connector has a housing with an axially movable plunger within the housing and each being in axial alignment. A spring is used for biasing the plunger axially toward and into engagement with the breech pin. The breech pin is selectively engageable and disengageable into lock and unlock positions, respectively, with the plunger and the housing. The plunger rotates the breech pin axially between the lock and unlock positions. A latch is provided for latching the plunger and breech pin in the lock position.Type: GrantFiled: December 7, 2000Date of Patent: April 13, 2004Assignee: Tuboscope I/P, Inc.Inventors: Brent Marsh, Robert Parker
