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.

A gas meter cabinet is adapted for mounting within a wall of a building. The cabinet has a body partially recessed within the building wall. A perforation at the top of the cabinet accommodates a gas line. A door is coupled to the body. A manifold connects a gas meter to a building gas system. The manifold has a downward facing inlet port, an upward facing outlet port, and a forward facing surface port, above the inlet port. A mounting flange is provided on the manifold for mounting the manifold to a base surface.

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.

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.

Dual purpose pipe stopper mechanism

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. Lowering of the tools by means of the insertion assemblies into and out of the pressurized pipe is made possible by manipulation of a gate valve in the fixture, which allows the upper part of the bore to be depressurized prior to removal and during the insertion of different ones of the insertion assemblies.

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. 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 it tool inlet, into which the sealing plug of the insertion assembly is screwed for a pressure-tight fit. Typically, one of the tools is a shell cutter, and another one is a bypass plug. They are individually inserted, in succession, through the fixture's bore and through the branching-saddle pipe stub, first, to cut, and later, to bypass, through the wall of the pipe. Lowering of the tools by means of the insertion assemblies into and out of the pressurized pipe is made possible by manipulation of the gate valve, which allows the upper part of the bore to be depressurized prior to removal and during the insertion of different ones of the insertion assemblies. Through a primary, valved port in the side of the barrel, gas may be diverted from the pipe, through the fixture and through a conduit, to a similar fixture on the other side of the break. A secondary valve, in communication with the upper part of the barrel above the gate valve, permits depressurization of that part of the barrel during insertion and removal of the various tool-insertion assemblies while the gate valve is closed.

Pipeline repair method and apparatus

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.

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. The ovality-gage may be separated from the chamfering element and utilized alone or in combination with a coupled second ovality-gage for checking the ovality of pipes of different nominal diameters. A wall thickness gage is carried by the ovality tool whether it is alone or in combination with a chamfering element or a dual ovality-gage.

Universal plastic-pipe tool

A bore gauge having a fixed and an opposing automatically-adjustable contact anvil, each such anvil having an extended length in the direction of the axis of the bore being gauged, the gauge having a body about which is adjustably secured a reference plate which sets the depth at which the contact anvils make contact with the inner wall of the device the bore of which is being measured, the adjustable contact anvil being mechanically coupled to the dial-actuating rod of a dial indicator for reading the bore diameter.

Bore Gauge

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.
