ABSTRACT:
A coupling mechanism for interconnecting a drive spindle and a capping chuck, the mechanism including a coupling hub internally threaded for fastening to the spindle. A collar is disposed around the hub, and the hub has an arcuate groove in which a spring is positioned and retained by a removable plate. The hub has lugs integral therewith extending into receiving slots in a floating ring positioned in the collar below the hub. The floating ring is elliptically shaped for lateral movement relative to the collar along a first axis, and has feet integral therewith extending into keyways in a coupling member laterally movable relative to the ring along a second axis right angularly related to the first axis. The coupling member drives a chuck sleeve through a torsion spring to release the closure upon achieving a predetermined degree of tightness on a container.
