  • Patent number: 3988051
    Abstract: Essentially, the clamping means comprise the basic, operative structure of the known lever-wrench pliers, a common type thereof which is sold under the trade mark "Vise Grip". According to the invention, however, an electrical conductor is mechanically and conductively coupled to the fixed head of one of the handles of the pliers. Too, the heads of the working handles of the pliers have been adapted to envelop and compressively clasp a terminal post of a storage battery, or a grounding rod, and the like. In a first embodiment of the invention, the heads have arcuate jaws formed therein compressively to enclose a terminal post. In another embodiment, the heads carry portions of the electrical conductor and cause a loop of the conductor to clamp about the terminal post, or whatever.
