Abstract: An improved pliers having a first and second member. The first member includes a jaw operatively connected to a first handle, and the second member includes a second jaw operatively connected to a second handle. A slot is located in one of the members between the jaw and the handle. A pin in the other member extends into the slot and is secured therein to hold the members together while permitting relative motion between them. The slot may have different shapes but must be long and wide enough to allow the pin unrestricted motion. A projection extends from one of the members and engages a pivot area which may be a surface or a notch on the other member. In two embodiments of this invention, two pivot notches are used to give two different ranges of motion to the jaws. Different shapes of jaws may be used for specialized purposes, such as, opening pipe clamps or removing oil filters.

Abstract: An audible torque wrench including a head having a tool connecting part. A handle is operatively attached to the head in order to cause rotation thereof. A grip is pivotably attached at one of its ends to the handle. A spring is fastened between the grip and the handle at the end opposite the pivot on the grip. The spring is mounted so that it may be moved longitudinally along the length of the handle in order to change the torque settings for the wrench. An audible clicker spring is fastened to either the handle or the grip at a position between them so that when a force is applied to the grip, to rotate it about the head, the grip compresses the spring and biases the resilient member until it reaches the position where an audible signal is made.
