Device for temporarily rigidly uniting a free circular element with a fixed circular element

摘要

A device for temporarily holding fast a free circular element with respect to a fixed circular element having circular segments with tangential ramps and a rigid ring with rollers axially rotatable thereon for local thrust against the ramps to cause locking of the free circular element with respect to the fixed circular element. Clevises bearing axial grooved rollers riding on the rigid ring, with the clevises connected to the segments by springs, providing an elastic restoring force to release the free circular element with respect to the fixed circular element.
