| 20080203681 | Quick-release jaws with single-piece bearing chuck - A workholding chuck can use actuating members that pivot within a non-split unitary front bearing. The non-split unitary front bearing can include pockets in its central bore that can allow a spherical section of an actuator arm to be inserted into the bearing. The spherical section can include radially recessed areas to facilitate the insertion into the bearing. The jaws can be retained to the actuator arms through the use of a quick-release assembly. The quick-release assembly allows the jaws to easily and quickly be changed to allow the chuck to grasp different workpieces. | 08-28-2008 |
| 20090206560 | QUICK-RELEASE JAWS WITH SINGLE-PIECE BEARING CHUCK - A system, in certain embodiments, includes a cutting tool, a drive and a chuck rotatable by the drive. The chuck includes multiple actuator arms, multiple jaws and multiple spring-loaded lock pins coupling the respective jaws to the respective actuator arms. | 08-20-2009 |
