ABSTRACT:
A self-adjusting tool having first and second elongated members, each of which have a workend and an oppositely located handle means for applying force to the tool. The first member includes a raceway positioned intermediate of the work end and handle. A connector is provided adjacent to the work ends for slideably and pivotally connecting the first and second members together. The connector includes an elongated slot in the first member having ratchet teeth along at least a portion of one edge thereof and a pawl positioned to slide within the slot and to pivotally engage the ratchet teeth. A fastener for securing the first and second members slideably together and securing the pawl in the slot is provided as part of the connector. A torsion arm with first and second ends is operably positioned between the first and second members. The first end includes a torsion element connected to the second member and the second end is slideably positioned within the raceway. The torsion arm is of sufficient length to space the work ends away form each other to their maximum extent when no force is applied to the handles. An initial restraining member is positioned within said raceway to initially restrain movement of the torsion arm therein.
