Abstract: Chuck for use with manual or powered driver having rotatable shaft, the chuck including a body member and jaws slidably positioned in angled passageways formed in the body. The chuck further includes a nut rotatably mounted relative to the body member and in engagement with threads on the jaws. A generally cylindrical front sleeve member is disposed in driving engagement with the nut and overlying the nose section of the body so that when the front sleeve member is rotated with respect to the body, the jaws will be moved thereby to grip the shaft of a tool. A spring member is biased to engage the sleeve member and is disposed selectively rotatably with respect to the nut. When the nut is tightened, the spring member becomes locked to the body member and restrains the nut from loosening during vibration of the chuck in use for its intended purpose.

Abstract: A chuck for use with a manual or powered driver including a nut (46, 48) rotatably mounted on the chuck body and in engagement with the threads of the chuck jaws (18). Aspects of the chuck jaws, such as the jaw face, are manipulatively formed by selective redistribution of metal. Formation of the chuck jaws in this manner is distinguishable from jaws formed by prior art machining techniques due to the structural orientation of grain in the metal. Forming of the chuck jaws preferably occurs at low applied temperature, i.e., not exceeding 538 degrees Celsius.

Abstract: A three-jaw (34) chuck is provided with a unitary nut (48) rotatably mounted relative the body (16) and a retaining member (46) located so as to contact a portion of the unitary nut (48) to prevent axial movement of the nut (48) in the forward direction. The nut (48) may include a first portion (56) of a first outside diameter and a second portion (58) extending axially outward from the first portion with an outside diameter less than the first outside diameter. A sleeve retaining snap ring (70) may be provided engaging the sleeve (12) for retaining the sleeve (12) on the body (16).

Abstract: A chuck (15) for use with a manual or powdered driver having a rotatable drive shaft including a primary tightening mechanism utilizing a three-jaw (65) assembly actuated by a nut (80) or tightening ring and a supplemental tightening mechanism (95). The supplemental tightening mechanism (95) includes a camming portion (100) defining a tightening cam profile (105) and a release cam profile (110). The supplemental tightening mechanism further includes a plurality of lever bars (120), one end of each of the lever bars forming a cam follower (125) and the other end of each of the lever bars (120) operatively associated with the nut (80) so that when the supplemental tightening mechanism (95) is actuated in a tightening direction, the lever bars (120) will force the nut forward to produce an enhanced tightening force on the tool through the jaws (65), and when the rear sleeve (115) is rotated in a release direction, the force applied to the nut (80) by the lever bars (120) will be released.
