DEFINITION

Classification: 81/381

(under subclass 342) Tools including a handle-lever and a handle-member, in which the handle-lever is pivoted to the movable jaw, both the movable jaw and the handle-lever being pivoted to the handle-member.

(1) Note. The handle-lever may be connected to the handle-member by a toggle-link linkage wherein both links are integral with the respective jaw or handle-lever.

(2) Note. A socket joint is considered as a pivot in this and indented subclasses.

(3) Note. Included in this subclass are tools in which the movable jaw is directly pivoted to the handle-lever; for indirectly or linked pivoted jaws see subclass 383.
