  • Multi-position locking adjustable wrench
    Patent number: 5540125
    Abstract: An adjustable wrench having selectable lockable positions. Selectable locking positions are obtained using a pair of locking ball bearings that engage a plurality of recesses located on both ends of the thumb wheel. The recesses on the end are offset to the recesses on the other end. The width of the recesses on one end is greater than the width of the recesses on the other end. The wrench retains its "locked" position even when jarred, yet can be easily moved to a new set position by rotating the thumb wheel to the next selectable notch.
