Description:
The patent is for two fixed jaws and a "stop" designed to firmly hold a correspondingly shaped nut; the wrench would have to slide on and off from the side. The wrench is intended to work on axle nuts which typically are recessed in a hub, so it is not clear how this patent could work in a real-world situation.
