Patent number: 8371779Abstract: A chuck including a body having a tail section defining an annular shoulder and a nose section having an axial bore and angularly disposed passageways intersecting the axial bore. An O-ring is disposed in the annular shoulder and a plurality of jaws is slidably positioned in the passageways. A nut is rotatably mounted on the body in engagement with threads on the jaws. A first sleeve and a second sleeve each define a gripping surface thereon and one of the first and second sleeves is axially reciprocal on the body. The one of the first and second sleeves defines an annular groove on an inner surface thereof having a first shoulder and a second shoulder. The O-ring is received in the groove such that axial motion of the one of the first and the second sleeve is limited by abutment of the O-ring with said first and second shoulders.Type: GrantFiled: July 11, 2011Date of Patent: February 12, 2013Assignee: Jacobs Chuck Manufacturing CompanyInventors: Stephen W. Steadings, William C. Buck, Christopher B. Barton

Patent number: 7976253Abstract: 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.Type: GrantFiled: April 2, 2010Date of Patent: July 12, 2011Assignee: Jacobs Chuck Manufacturing CompanyInventors: Stephen W.

Patent number: 7160065Abstract: 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.Type: GrantFiled: March 17, 2006Date of Patent: January 9, 2007Assignee: Jacobs Chuck Manufacturing CompanyInventors: Mark S.
