CHUCK APPARATUS FOR SUPPORTING CONTAINERS BY THE FINISH PORTION THEREOF

摘要

Apparatus for supporting a container in a vertical position by the finish portion thereof, including a plurality of chuck jaws pivotally movable between an outwardly spread open position and a radially inward closed position wherein the jaws substantially completely enclose the container finish and support the container by it. The jaws are movable to the closed position by means of a vertically movable annular sleeve adapted to engage and surround the jaws. The jaws are hung on pivots and swing outward to the open position by the force of gravity when the sleeve is moved out of engagement from them.
