Abstract A quickly adjustable ratchet wrench is essen- tially a crescent wrench modified by eliminating the ad- justing screw and substituting a locking member and z lever to engage and disengage the locking member with the rack on the movable wrench jaw. A tension spring lightly biases the movable jaw toward closed position. With the locking member disengaged from the rack, the movable jaw may be manually opened, and when the movable jaw is released the light spring bias closes the jaws on a bolt head. when the wrench jaws are engaged with a bolt head, rotation of the lever arm against the wrench handle engages the locking member with the rack to turn the bolt, while rotation of the lever arm away from the handle disengages the locking member and per- mits the jaws to open against the light spring bias and slip over the angles of the bolt head; thus eliminating the need to remove and replace the wrench on the bolt head.
