A hands-free system for connecting and disconnecting a tool from an adjustable length extension pole. The system includes first and second slidably interconnected elongated members, a tool-holding assembly releasably coupled to the second elongated member, and a locking assembly disposed between the first and second elongated members. The relative sliding of the first and second elongated members can be selectively restrained by rotating the first and second elongated members relative to one another. The tool-holding assembly can be disconnected from the second elongated member by sliding the first and second elongated members together.

An improved method and article of manufacture for introducing a locator wire into an interior portion of a pressurized, or non-pressurized, subterranean or otherwise concealed plastic pipeline. The present invention introduces a locator wire into a plastic pipeline while simultaneously minimizing the escape potential of a transported volume, such as, but not limited to, gas, water, sewerage or oil. A locator wire feeding unit initially feeds the locator wire through a locator wire alignment coupling and proceeds thereafter to project the locator wire through a valve assembly, a locator saddle, and ultimately into a plastic pipe.

A readily attachable and detachable coupling for fluid conduits including a receptacle member having a passageway therethrough and having a notch formed in the external surface communicating with the passageway, the notch having a forward wall inclined at an acute angle to the member longitudinal axis and a rearward wall which is substantially perpendicular to the longitudinal axis, and a plug member of a diameter to be slideably received within the receptacle member passageway, the plug member having an enlarged external diameter portion spaced from the end, the receptacle member having a retention wire received therearound and extending within the notch and gaskets within the passageway so that when the plug member is inserted into the receptacle passageway, the enlarged diameter portion can push past the retention wire because the retention wire can expand against the inclined planar wall of the notch but after having passed is prohibited from being withdrawn from the receptacle member by the retention wire.

An adjustable height sprinkler apparatus having three tubular portions telescopically received within each other. The base portion is buried vertically in the ground and connected to a source of water pressure at the lower end, the upper end being adjacent the earth's surface. A second tubular extension member is vertically positionable by telescopic displacement relative to the base member and includes a coupling for sealably retaining the extension member in the selected vertical position. A third tubular pop-up member is telescopically positioned in the extension member and slidable downwardly by gravity and displaced upwardly when water pressure is applied to the sprinkler, the pop-up member having an enlarged diameter portion at the upper end with means for attaching a sprinkler head. In the preferred embodiment the upper end of the tubular extension is in a plane displaced relative to the tubular axis and the lower surface of the enlarged portion of the pop-up member is in a similar displaced plane so that when water pressure ceases and the pop-up member falls downwardly, the planar surfaces engage each other to maintain a preselected angular relationship between the pop-up member and the extension member.

A corrosion proof meter riser for attachment to a subsurface polyethylene pipe carrying fluid at high pressure, which comprises a length of selected polyethylene tubing adapted to be attached at a first end to said polyethylene pipe, and heat seal means and cylindrical seal for attaching the second end of the polyethylene tubing to a first end of a selected length of fiberglass tube of substantially the same radial dimensions. The fiberglass tube is molded with a circumferential ridge near its second end. A riser body, comprising a metal pipe of suitable interior diameter has a coupling at one end which is screwed to the pipe. The coupling has an internal shoulder which cooperates with the ridge on the outer surface of the fiberglass tube, so that when the joined fiberglass and polyethylene tubing is inserted into the body, the ridge rests on the shoulder and can be locked in position by a nut to seal that end of the body. The polyethylene tubing extends out from the other end of the body and is sealed by means of a pipe cap which slidably seals around the surface of the polyethylene tubing and screws onto the end of the pipe body.

Meter riser

A safety valve for pressure fluid flow lines and which may be utilized in combination with a punch tee, said valve being responsive to pressure differentials acting thereacross for automatically closing to preclude accidental loss of pressure fluid from the line. The valve comprises body means adjustably secured in communication with the pressure fluid of the flow line, valve seat means provided on the body means, cage means carried by the body means, ball means loosely disposed in the cage means to provide a normally open position for the valve and responsive to pressure differentials thereacross for automatically engaging the valve seat to provide a closed position for the valve, locking means adjustably disposed in the proximity of the body means for providing a predetermined positioning or setting for the body means for calibrating the pressure responsive sensitivity for the ball means, and means for selectively opening the valve against said closing pressure differential.

Safety valve

Improvements in a ball-type shut off valve including a resilient seating means whereby an O-ring is included in conjunction with the seat to provide both metal-to-metal and metal-to-O-ring seating. Also included is a removable ball carrying means carried by the actuator arm, whereby straight through assembly of the actuator arm may be made directly through the valve operator opening thereby reducing the possibility of damaging seals on assembly and disassembly.
