DEFINITION

Classification: 81/407

(under subclass 385) Tools including means movably connecting the handles to each other, said means constraining the handles for slidable movement relative to each other thereby changing the position of a bearing portion at which one handle pivots with respect to the other.

(1) Note. For adjustment of the jaws the operator grasps one handle in each hand and shifts the fulcrum of the handles by moving one handle substantially along its longitudinal axis. In many cases the handles must be separated by pivoting at the joint prior to the shifting movement.
