Abstract: A chuck for use with a manual or powered driver having a drive shaft, the chuck including a body having a nose section and a tail section, the tail section configured to rotate with a drive shaft of a driver and the nose section having an axial bore formed therein, plurality of jaws disposed within the body in communication with the bore, each of the jaws having a jaw face formed thereon for engagement with a tool shaft, and a visual indicator disposed on the body and including a surface on which is defined a visual indicia that is in operative communication with the jaws so that movement of the jaws to a predetermined position with respect to the bore exposes the indicia to view from outside the chuck and so that movement of the jaws from the predetermined position blocks the indicia from view from outside the chuck.

Abstract: A chuck for use with a power driver includes a generally cylindrical body, a plurality of jaws and a driving disk axially moveably disposed about the body in driving engagement with the jaws so that axial movement of the driving disk with respect to the body moves the jaws toward or away from the chuck body axis. The driving disk defines a threaded outer circumferential surface that engages a threaded inner circumferential surface of a generally cylindrical sleeve so that relative rotation between the sleeve and driving disk axially moves the driving disk with respect to the body. The driving disk defines a plurality of cylindrical slots extending at least partially radially therethrough. Each jaw includes a portion thereof that is shaped cooperatively with respect to the cylindrical slot and that is received thereby so that the jaw is axially fixed, and radially slidable with respect to the driving disk.
