Abstract
Abstract A capper chuck device for applying a rotatable closure cap to a container wherein closure cap retaining jaws are movable by a toggle linkage arrangement to retain a closure cap therebetween responsive to an externally applied force, and wherein adjustable torque transfer means are adapted to release the jaws from the closure cap after a predetermined rotational torque has been applied to the cap in assemblying it onto the container.
