  • Patent number: 6533291
    Abstract: A chuck includes a driver disposed on a chuck body and in engagement with the jaws so that at least one of rotation and axial movement of the driver with respect to the body opens or closes the jaws. A first detent is disposed in the body in communication with the jaws. At least one of the jaws defines a catch at a predetermined position so that the catch engages the first detent when the jaws are at a predetermined position on the body with respect to a chuck bore.

  • Publication number: 20030006567
    Abstract: A chuck for use with a manual or powered driver having a housing and a rotatable drive shaft extending therefrom is provided. The chuck includes a generally cylindrical body member having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face formed on one side thereof and threads formed on the opposite side thereof. A nut is rotatably mounted on the body in engagement with the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A locking member, in a first axial position, is rotatable with respect to the driver housing. In a second axial position, it operatively engages the housing and the nut so that the locking member is rotationally held to the housing and the nut so that the nut is rotationally held to the housing. The locking member is axially reciprocal between the first axial position and the second axial position.

  • Publication number: 20020074745
    Abstract: A chuck for use with a manual or powered driver including a generally cylindrical body having a nose section and a tail section. The tail section defines an axial bore formed therein to mate with the drive shaft of the driver and the nose section defines an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting the axial bore. A plurality of jaws are slidably positioned in each passageway and each jaw defines a jaw face formed on one side and threads formed on the opposite side. A nut is disposed about the body for rotational movement with respect to the body and is in driving engagement with the jaw threads. A generally cylindrical front sleeve overlays the nose section of the body. A generally cylindrical nut retainer is disposed about the body and includes a frusto-conical portion.

  • Publication number: 20020063401
    Abstract: A chuck includes a generally cylindrical body and a plurality of jaws reciprocally disposed in the body in communication with a central bore in the body. A first detent extends radially into the central bore and is releasable in a radially outward direction. Upon insertion of an elongated tool shaft having a polygonal cross section into the bore so that a groove in the tool shaft is aligned with the first detent, the first detent engages the groove and axially retains the tool shaft. Upon movement of the jaws so that the jaw faces engage flat sides of the tool shaft, the jaws rotationally retain the tool shaft.

  • Patent number: 6279918
    Abstract: Chuck for use with a manual or powered driver including a nut rotatably mounted on the chuck body and in engagement with the threads of the chuck jaws. The chuck includes a self-contained anti-friction bearing assembly disposed between the nut and a thrust ring, as well as a generally cylindrical front sleeve member in driving engagement with the nut and overlying a nose section of the body of the chuck so that when the front sleeve member is rotated with respect to the body member, the jaws will be moved thereby. The chuck also includes a rust resistant decorative nosepiece as well as an improved nut retainer member.

  • Patent number: 6068266
    Abstract: Chuck for use with a manual or powered driver including a nut rotatably mounted on the chuck body and in engagement with the threads of the chuck jaws. The chuck includes a self-contained anti-friction bearing assembly disposed between the nut and a thrust ring, as well as a generally cylindrical front sleeve member in driving engagement with the nut and overlying a nose section of the body of the chuck so that when the front sleeve member is rotated with respect to the body member, the jaws will be moved thereby.

  • Patent number: 5816582
    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: 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 sleeve member is disposed in driving engagement with the nut and overlying the nose section of the body so that when the sleeve member is rotated with respect to the body, the jaws will be moved thereby to grip the shank of a tool. A pawl member is biased to engage the sleeve member and is disposed selectively rotatably with respect to the body member. When the nut is tightened, the pawl member can be disposed to become nonrotatable with respect to the body member and restrains the nut from loosening during vibration of the chuck in use for its intended purpose.
