Abstract
A clamp device for joining a flanged connection. The clamp device has a plurality of arcuate segments, wherein each of the arcuate segments has two ends. A pivot couples at least one end of each arcuate segment to another of the arcuate segments to produce a chain of arcuate segments that extend from a first end to a second end. The chain of arcuate segments is configurable into an annular structure when the first end is brought into abutment with the second end. A torsion spring is disposed around each pivot. Each torsion spring acts to bias the arcuate segments into the configuration that produces the annular structure. A rocking bolt is coupled to the second end of the chain of arcuate segments. The rocking bolt is joined to the second end by a second pivot and is positionable throughout a predetermined range. A biasing element is provided for biasing the rocking bolt into one position within the predetermined range.
