Abstract:
A wrench which comprises:a handler;a pair of jaws mounted on one end of said handle;a fixed one of said pair of jaws being integral with said one end and a moveable one of said jaws is mounted on said one end in operable combination with said fixed jaw to permit gripping a fastener positioned between said pair of jaws;said fixed jaw and said moveable jaw each having a gripping surface;said gripping surface of said fixed jaw and said gripping surface of said moveable jaw facing one another to permit gripping a fastener positioned between said gripping surfaces;means for moving said moveable jaw relative to said fixed jaw to provide a spacing between said gripping surfaces required for positioning a fastener between said gripping surfaces;said gripping surface of each jaw having a contoured area 42 and flat area (44);said contoured area 43 having a central portion being a first pair of facets (46,48) meeting perpendicularly;said contoured area (43) having a second pair of facets (50, 52), one of said second pair of facets being on one side of said first pair of facets and another one of said second pair of facets being on an opposite side of said first pair of facets;one facet (50) of said second pair of facets extending from an edge of one facet (46) of said first pair of facets at an inclined angle of 15.degree. and another facet (52) of said second pair of facets extending from an edge of another facet (48) of said first pair of facets at an inclined angle of 15.degree. and wherein said one facet (50) of said second pair of facets is oriented at an angle of 120.degree. with respect to said another facet (52) of said second pair of facets;each of said second pair of facets (50, 52) being inclined at an angle of 60.degree. with respect to direction of travel of said moveable jaw (14B);said surfaces of said jaws operably arranged to permit a fastener having a square cross section be positioned between said jaws with said first pair of facets of said fixed jaw positioned against one pair of sides of said fastener having a square cross section and with said first pair of facets of said moveable jaw positioned against an opposite pair of sides of said fastener having a square cross section; andsaid surfaces of said jaws operably arranged to permit a fastener having a hexagonal cross section be positioned between said jaws with said second pair of facets of said fixed jaw positioned against one pair of sides of said fastener having a hexagonal cross section and with said second pair of facets of said moveable jaw positioned against an opposite pair of sides of said fastener having a hexagonal cross section; andsaid flat area (44) of each jaw surface being parallel to one another and perpendicular to the direction of travel of movable jaw (14) providing that a fastener having a cross section with parallel sides is positionable between said flat areas of said gripping surface with one side of said fastener against said flat area of said fixed jaw and an opposite side of said fastener against said flat area of said movable jaw.
