Abstract
A chuck is provided having a body, oblique guides converging toward a forward portion of the body, and a groove around the body. A slidable jaw within each guide includes outer threads. A rotatable mechanism engaging the groove includes threads for engaging the jaw threads. A toothed member extends around the body. An inner sleeve extends over and rotates the mechanism, while moving the jaws toward the forward portion. An outer sleeve extends over the inner sleeve. A metal intermediate sleeve between the inner and outer sleeves engages two spring members engaged with the inner sleeve. A first torque application rotates the intermediate sleeve with respect to the inner sleeve and causes one of the spring members to ratchet with the toothed member. A greater second torque application to the intermediate sleeve causes the other spring member to prevent rotation between the intermediate and inner sleeves.
