Addison G DuBois - patent attorney
My invention relates to an improvement in wrenches, and the object is to provide means for automatically rotating the nut without the necessity, of rotating the handle for turning the nut upon the bolt. The nut is caused to rotate by merely pressing the handles of the wrench together, which gives the nut complete rotation.
