ABSTRACT:
A rachet wrench fitted with a rotatable wrench lug that completely encloses a non-circular wrench opening, when installed, with the wrench lug formed of two assembled units, one of which is detachable to permit the wrench lug to be installed sidewise about a fitting on a tube, pipe or cable. A handle joins a circular open wrench section formed of two fixed arcuate shaped jaws in which a first wrench unit is rotatably mounted, with the first wrench unit in the form of a split ring, of a profile similar to that of the two fixed jaws, with the opening of the split periphery section of the first wrench formed as the same size as that of the opening between the ends of the two fixed jaws. The second wrench unit is a split ring shape of a size to fit inside the first wrench unit and between the first wrench unit opening so that when the first wrench unit is assembled to the second wrench unit, they form a closed circular ring, the exterior of which is shaped with rachet teeth and the interior of which is shaped with flats of a size to fit about the exterior of a polygonal sectional nut or other torque fastener. Pawls are internally mounted to a pivotable selector unit so as to alternately grip the external rachet teeth of the assembled wrench units to permit rotation of the wrench unit alternately in one or the other direction, in the fixed wrench jaws, with respect to the handle and fixed jaws.
