ABSTRACT:
A hand held torque wrench with augmenting means is provided which includes a linkage assembly to join a drive input with an output wrench socket. The linkage assembly consists of a drive link extending from the input socket and coacting with a conversion link extending to a ratchet disposed about the output socket of the device. Rotation of the drive link pivots the conversion link to transfer torque from the input to the output socket. A pawl on the driven link is provided to coact with a ratchet which encircles the output socket. A guide means is disposed in the interior of the housing of the device to coact with the linkage assembly to maintain proper alignment during a torque operation, such that stress and force are substantially reduced or dissipated, if not eliminated, during the operation.
