ABSTRACT:
Chucking apparatus is disclosed for engaging articles such as screw-type caps for applying the caps to containers. Caps are bottom or center fed to a fluid operated chuck device which grips the caps and screws them onto a container. The chuck device comprises a plurality of jaw members pivotable to a cap gripping position. An annularly shaped, resilient member surrounds the jaw members. As fluid under pressure is introduced into a chamber in fluid communication with the resilient member, the member is compressed causing the jaw members to pivot to the cap gripping position. The chuck device, which is connected to a constantly operating motor through a torque clutch, screws the cap onto a threaded portion of the container. The torque clutch is set such that when the cap is properly tightened on the container, the resistance to further tightening causes the clutch to disengage. The fluid under pressure is released from the chamber to allow the compressed resilient member to return to its original shape, thereby releasing jaw members from engagement with the cap. The chuck device is then separated from the capped container and the process repeated for the next container.
