摘要： A chuck comprises radially slidable work-gripping jaws with racks, radially movable sliders with racks engageable with the racks of the jaws, and an axially movable slider-actuating means for radially moving the sliders in unison. Spring means are provided which urge the racks of both the sliders and jaws out of engagement, and a locking or restraining device is provided to force the racks of the sliders and jaws into engagement against the force of the spring means to make the connection between the sliders and jaws. When the locking or restraining device is unlocked, the connection is broken to allow the jaws to be radially moved independently of the sliders for radial adjustment.
