Abstract
A wrench is disclosed having hinged jaws which may be opened to be placed about an obstructed bolt, ferrule or other threaded connector. Once placed about the connector the jaws of the wrench are closed to provide contact between the interior flats of the wrench and the corresponding flats of the connector. Complemental elements moveable in parallel planes orthogonal to the jaws pivot axis and drive axis project from respective jaws and provide a means for engaging a torque-applying tool. Upon closure of the wrench jaws and elements are brought into register to permit attachment of the tool and thereby lock the hinged jaws of the wrench together.
Claims6
A wrench comprising:
- a pair of jaw members each having opposed ends,
- means on one of said end of each of said jaw members mounting the latter for movement about a pivot axis between open and closed positions,
- said jaw members having opposed wrench portions adapted for engagement with corresponding opposed flats of a connector when the jaw members are in their closed position, and
- means on the other ends of said jaw members for holding the jaw members closed during application of driving torque thereto,
- said holding means including complemental elements on respective jaw members movable along parallel, axially spaced planes orthogonal to the pivot axis and having a configuration causing said elements to move into registration with each other when said jaw members are closed, said elements upon registration thereof being adapted for engagement by a torque-applying tool.
