A coupling has first and second segments attached to one another end to end surrounding a central space for receiving pipe elements. A spring assembly attaches the segments at one end and an adjustable attachment assembly attaches the segments at the opposite end. The spring assembly biases the segments away from one another sufficient to permit insertion of the pipe elements into the central space while the segments are attached to one another. The coupling may include a split ring toothed retainer for coupling plain end pipe elements, or it may have arcuate keys which engage grooved or shouldered pipe elements.

Sprung coupling

Assembly for connecting a branch line to a fire-sprinkler head, and for adjusting longitudinal and horizontal position of the sprinkler head. The assembly may include: a first-pipe section, a second-pipe section, and a third-pipe section. First-pipe section has telescoping lower and upper pipes configured to travel axially relative to each other upwardly and downwardly along a longitudinal axis. Second-pipe section has telescoping right, and left pipes configured to travel axially relative to each other along a horizontal axis. Third-pipe section is between first-pipe section and second-pipe section, and is curved. First-pipe section is configured to engage a sprinkler head and permit the sprinkler head to travel longitudinally upon telescopic adjustment of the lower and upper pipes. Second-pipe section attaches to the sprinkler-branch line, and permits the sprinkler head to travel horizontally upon telescopic adjustment of the right and left pipes with respect to each other.

Adjustable assembly for connecting a sprinkler-branch line to a fire-sprinkler head

A preassembled combination connects a captured pipe element to a second pipe element. First and second segments are connected end to end surrounding a central space for axially receiving the second pipe element. The segments are configured to be drawn toward one another and into engagement with the pipe elements. An annular body forms the captured pipe element. An end face of the captured pipe element is retained within the central space by engagement between a bead projecting from a sealing surface of the captured pipe element and the coupling assembly.

Captured element coupling

A coupling has first and second segments attached to one another end to end surrounding a central space for receiving pipe elements. A spring assembly attaches the segments to one another at a first end and an adjustable attachment assembly attaches the segments to one another at a second end opposite to the first end. The spring assembly cooperates with the attachment assembly to bias the second ends of the segments away from one another sufficient to permit insertion of the pipe elements into the central space while the segments are attached to one another.

A preassembled combination for connecting a captured pipe element to a second pipe element includes a plurality of segments attached to one another end to end to form a loop around a central space. A ring seal is positioned in channels defined by the segments. The captured pipe element has a first end positioned in the central space. The coupling is configured such that once the end of the second pipe element is inserted into the central space the segments can be drawn toward one another to join the second pipe element with the captured pipe element. A method of manufacturing the combination includes the steps of engaging a ring seal with a pipe element, positioning the ring seal in a channel of the segments and attaching the segments to one another.
