ABSTRACT:
A hand operated ratchet tool includes first and second pivotally coupled jaws, first and second links pivotally coupled to the first and second jaws, respectively, a third link pivotally coupled in common with the first and second links, and first and second handles pivotally coupled with the first and third links, respectively, and with one another. First and second pawls are mounted on the pivots between the third link and second handle and between the first link and first handle, respectively. Each alternately engage with teeth provided along a semi-circular edge of the second link to rotate the second link in a direction which closes the adjoining working faces of the jaws. The first pawl has two separate sets of teeth configured to respectively engage with the link teeth when the second link is being rotated in either of two opposing directions to open and close the jaws. A selector mechanism permits selective engagement of either sets of teeth of the first pawl and engagement and disengagement of the second pawl with the link teeth. A pivot adjustment is provided to take up slack in the linkage from wear of the parts.
