Abstract
An adjustable wrench having a housing with a handle and having a plurality of jaws that extend out the bottom of the housing and move radially with respect to one another. The housing contains a control disk which may be locked to the housing to prevent the jaws from turning with respect to the housing. A jaw adjusting disk is disposed beneath the control disk and extends out the bottom of the housing. The adjusting disk contains cams that open and close the jaws depending upon the direction of rotation of the adjusting disk.
Claims66
An adjustable wrench comprising
- a housing and a handle secure to the housing,
- said housing having a top and bottom and an axis and being open at the bottom, said open bottom being concentric with the axis,
- a first annular disk concentrically mounted in the housing and rotatable about the axis,
- a plurality of radial slots in the disk and a circular gear on its periphery,
- a pawl on the handle for selectively engaging the circular gear to cause the first disk to rotate with the handle and housing,
- a plurality of jaws extending out the bottom of the housing and each engaging one of the slots of the disk so that the jaws may move only radially with respect to the disk,
- a second disk concentrically secured to the housing and rotatable therewith below the first disk,
- and cam means formed in the second disk for simultaneously moving the jaws radially inwardly and outwardly as controlled by the slots when the second disk is rotated in the housing.

- a second disk concentrically secured to the housing and rotatable therewith below the first disk,
- cam means including a first set of cams for moving the jaws radially inwardly when the second disk is rotated in one direction and a second set of cams for moving the jaws radially outwardly when the second disk is rotated in an opposite direction, and
- said second disk being annular in shape having an opening through the center thereof through which the jaws extend, and the first set of cams defining the margins of the opening.

An adjustable wrench head comprising
- a housing having an axis,
- a plurality of jaws mounted on the housing and extending beyond the housing parallel to the axis, said jaws having inner and outer surfaces and inner and outer ends, said outer surfaces lying intermediate the ends of the jaws,
- and adjusting means surrounding the jaws and having radially facing cams continuously engaging the outer surfaces of the jaws for manually moving the jaws toward the axis when the adjusting means is rotated so as to cause the jaws to close about and engage a workpiece placed within them.
An adjustable wrench head comprising
- a housing having an axis,
- a plurality of parallel jaws having gripping faces facing one another and parallel to the housing axis,
- said jaws having inner and outer ends and an intermediate portion with the housing surrounding the inner ends,
- an annular adjusting disk surrounding the jaws at their intermediate portions and having an inner surface facing said intermediate portions and engaging one another and having an upper and lower portion above and below the inner surface with respect to the axis,
- cam means on the inner surface of the adjusting disk and the intermediate portions of the jaws where they engage one another causing said jaws to move radially with respect to the axis when the adjusting disk is rotated with respect to the jaws,
- means rotatably mounting the adjusting disk in the housing,
- and means carried by the jaws engaging the upper and lower portions of the disk for retaining the jaws within the disk.

An adjustable wrench comprising
- a housing and a handle secure to the housing,
- said housing having a top and bottom and an axis and being open at the bottom, said open bottom being concentric with the axis,
- a first disk concentrically mounted in the housing and rotatable about the axis,
- a plurality of radial slots in the disk and a circular gear on its periphery,
- a pawl connected to the housing for selectively engaging the circular gear to cause the first disk to rotate with the handle and housing,
- a plurality of jaws extending out the bottom of the housing and each engaging one of the slots of the disk so that the jaws may move only radially with respect to the disk,
- a second disk concentrically secured to the housing and rotatable therewith below the first disk,
- and cam surfaces on the second disk for simultaneously moving the jaws radially inwardly and outwardly as controlled by the slots when the second disk is rotated in the housing.
5 more elements
An adjustable wrench head comprising
- a housing having an axis,
- a plurality of jaws mounted on the housing and extending beyond the housing parallel to the axis, said jaws having inner and outer surfaces,
- a control member in the housing for limiting the jaws to radial travel on the head with respect to the housing,
- an adjusting member surrounding the jaws and having radially facing cams engaging the outer surfaces of the jaws for moving the jaws radially with respect to the axis when the adjusting member is rotated,
- and control means operatively connected to the adjusting member for preventing it from rotating relative to the control member in response to reactive force applied to the jaws by a workpiece engaged by the jaws.
