Patent number: 6126369Abstract: A tool for tapping from a branch pipe into a main pipe to establish communication between the pipes. The tool has a bit for cutting a hole in the main pipe which is secured to an upstream end of a shaft for transmitting torque to the bit. The tool has a branch-engaging member engaged to the branch pipe adjacent to the downstream end of the branch pipe. The shaft has a threaded section engageable with a threaded section of the branch-engaging member so that as the shaft is rotated, the bit is driven along the longitudinal axis of the branch pipe toward the main pipe.Type: GrantFiled: May 9, 1994Date of Patent: October 3, 2000Inventor: Stephen L. Jiles

Patent number: 5595207Abstract: A tension actuated gas shutoff valve having a body with an inlet for receiving gas flow along a flow path from upstream to downstream and a piston slidable within the body. The piston slides in response to a longitudinal force applied across the valve between a first position wherein flow through the valve is prevented and a second position wherein flow through the valve is permitted.Type: GrantFiled: October 19, 1994Date of Patent: January 21, 1997Assignee: Southern California Gas CompanyInventor: Stephen L.

Patent number: 5358010Abstract: A dual purpose stopper having a deformable, resilient body resides in a branch, communicating with a pipe through an opening in the wall of the pipe. The stopper has a distendable rear portion which can be expanded radially to seal the branch, allowing removal of a mechanism used to actuate the stopper. When actuated, the stopper is shifted by the mechanism from the branch into the pipe, deforming the stopper and sealing the pipe.Type: GrantFiled: May 30, 1991Date of Patent: October 25, 1994Inventor: Stephen L.

Patent number: 5058620Abstract: A method for cutting an opening in the side of a pipe carrying gas under pressure, providing a bypass through the cut, and terminating the bypass when the pipe has been repaired, and apparatus for performing steps of the method. A branching saddle is bonded to the pipe, and a fixture is mounted on the pipe at the saddle. The fixture comprises a barrel through which various tool-insertion assemblies may be inserted.The tool-insertion assemblies typically include a shaft carrying a tool on one of its ends, a driving hub affixed near its opposite end, and a sealing plug slidably mounted axially on the shaft between the tool and the driving hub. The tools enter into the fixture's bore through a tool inlet, into which the sealing plug of the insertion assembly is screwed for a pressure-tight fit. The tools are individually inserted, in succession, through the fixture's bore and through the wall of the pipe.Type: GrantFiled: October 29, 1990Date of Patent: October 22, 1991Inventor: Stephen L. Jiles

Patent number: 5052431Abstract: A method is disclosed for cutting an opening in the side of a pipe carrying gas under pressure, providing a bypass through the cut, and terminating the bypass when the pipe has been repaired, along with apparatus for performing steps of the method. To provide the bypass, a branching saddle is bonded to the pipe, and a fixture is mounted on the pipe at the saddle. The fixture comprises a barrel having an inlet at one end, into which the pipe stub of the branching saddle extends, and a second inlet at its opposite end, through which various tool-insertion assemblies may be inserted, and an axial bore connecting the inlets. A gate valve, housed within a drum around the midsection of the barrel, is operable to divide the barrel so that the bore region in its upper part is pressure-isolated from that in its lower part.Type: GrantFiled: April 24, 1990Date of Patent: October 1, 1991Inventor: Stephen L. Jiles

Patent number: 5050310Abstract: A combined pipe chamfering tool and ovality gauge. One or more ovality gauge(s) is/are rotatably mounted on a chamfering tool. The gauges may serve to gauge different-size pipes to a given ovality standard or a given pipe size to different ovality standards.Type: GrantFiled: October 9, 1990Date of Patent: September 24, 1991Inventor: Stephen L. Jiles

Patent number: 5020401Abstract: A universal tool for inspecting and processing plastic pipe includes a cylindrical chamfering element with a cylindrical wall and a pipe-receiving opening therein terminating in a base ring, the base ring carrying a tapered pin having an axis parallel to the axis of the cylindrical chamfering element, the wall of the chamfering element having a slot therein proximate the tapered pin and a four-edged cutting element mounted on the outer surface of the cylindrical wall and having one edge of the cutting element protruding through the slot in proximity to the tapered pin, the pipe to be chamfered being forced into contact with the cutting edge by axial pressure on the chamfering element and rotation thereof, an ovality-gage being carried by the chamfering element and being arcuatley rotatable, at the end of the arc rotation of the gage causing rotational forces to be applied to the chamfering element, i.e., the ovality-gage acting as a handle for the chamfering element.Type: GrantFiled: October 13, 1989Date of Patent: June 4, 1991Inventor: Stephen L.

Patent number: 4501070Abstract: A tool is provided which incorporates a ring gauge into which the external tapered threads of a pipe are screwed by hand until tight, at which time a mechanical impulse of predetermined, consistent amplitude and duration is applied to the pipe-gauge combination from a hammer portion of the tool propelled, by rapidly-released spring energy against an anvil portion of the tool, the impulse being immediately coupled to the joint between the pipe threads being checked and the ring gauge, for overcoming any dirt or nicks in the thread which are restricting the engagement of the thread by the ring gauge.Type: GrantFiled: January 23, 1984Date of Patent: February 26, 1985Inventor: Stephen L. Jiles
