Abstract:
1. A hand tool for tightening and locking differently sized locknuts, the hand tool comprising: a first member having a proximate end comprising a first handle and a distal end comprising a first jaw; a second member having a proximate end comprising a second handle and a distal end comprising a second jaw; a pivot member comprising means for operably connecting said first and second members, said pivot member being disposed between the handles and the jaws so that the jaws pivot with movement of the handles; said first jaw being more distally disposed than the second jaw; said first jaw comprising a first elongate notch, and said second jaw comprising a second elongate notch, said first notch being more elongate than the second notch, said first notch comprising an elongate wall and an adjacent transversely disposed distal wall; wherein with said jaws closed on a first locknut, said first notch distal wall frictionally engages a first lug and the adjacent elongate wall is spacedly disposed from the first lug, and said second notch straddles a second lug of the first locknut; and wherein said jaws are closed on a second locknut having a smaller diameter than the first locknut, the first notch distal wall frictionally engages a first lug with the adjacent elongate wall spacedly disposed from the first lug, and the second notch does not straddle a second lug of the second locknut, said second notch comprises a proximately disposed adjacent convex curvilinear wall, said curvilinear wall is proximately disposed from said first and second notches, whereby said curvilinear wall frictionally engages a lug of a said first locknut with the jaws closed on the first locknut.
