ABSTRACT:
A gear wrench includes a lever 10 having a handle 11 at a distal end and a sector pinion gear 13 at a proximal end, rotatable in a cavity 26 of a fixed jaw body 18 by means of a pivot 14. The teeth of the pinion engage the teeth of a rack 21 disposed on a sliding jaw 25 so that rotation thereof adjusts the working size of the wrench. The pivot 14 is tangential to the sliding surface 85 of the sliding jaw thereby to ensure gripping pressure and turning of an object as small as the wrench is designed for. A spacer 27 causes the teeth of the rack to engage the pinion unless it is displaced to allow the rack to withdraw to the rear of the pinion, thereby to adjust the relative positioning of the sliding jaw and the fixed jaw. Gripping surface inserts 51, 52 have threads 59, 66 on one side for pipes, and are smooth on the other side for fittings, nuts and bolts; the inserts are held in place by thumb screws 53, 54 and stabilized by tabs 60, 61, 70, 71. A spring 46 between the fixed and sliding jaw provides ratcheting action.
