ABSTRACT:
A lid wrench for removing lids from jars and other containers, which lid wrench is characterized in a first embodiment by an elongated channel member having parallel, downwardly-extending flanges and spaced openings for selectively receiving the engaging finger of a single pivoting lug provided with inwardly-facing lug teeth. In a second embodiment, an elongated plate is provided with spaced openings for selectively receiving the engaging finger of the sliding pivoting lug. A fixed handle is attached to one end of the channel and plate, respectively, opposite the pivoting lug and an opening may be provided at the opposite end of the channel member and plate, respectively, for hanging the lid wrench on a nail or other support. A jaw plate is rigidly attached to the channel member and plate, respectively, at the fixed handle end thereof and a spring-biased, curved jaw, provided with multiple, spaced jaw teeth which face the lug teeth on the pivoting lug, 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 against the bias of the spring in a camming action against a jar lid or cap disposed between the jaw teeth and the lug teeth located on the pivoting lug, to loosen the lid or cap responsive to counterclockwise twisting of the lid wrench.
