ABSTRACT:
A self-adjusting lid wrench for removing lids from jars and other containers, which lid wrench is characterized by an elongated channel member having parallel, downwardly-extending flanges for pivotally receiving multiple, spaced, gravity-operated pivoting lugs provided with inwardly-facing lug teeth. A fixed handle is attached to the end of the channel opposite the pivoting lugs and an opening may be provided at the opposite end of the channel adjacent to the lugs, for locating the lid wrench on a nail or other support. A jaw plate is rigidly attached to the channel and the fixed handle and a curved jaw, provided with multiple, spaced jaw teeth which face the lug teeth on the pivoting lugs, is pivotally secured to the jaw plate and receives a jaw handle. Gripping and squeezing of the fixed handle and the jaw handle pivots the curved jaw in a camming action against a jar lid or cap disposed between the jaw teeth and the lug teeth located on a downwardly-oriented, lid-engaging pivoting lug, in order to loosen the lid or cap responsive to counterclockwise twisting of the lid wrench.
