DEFINITION

Classification: 81/342

(under subclass 300) Tools characterized by joint mechanism which converts relative motion of the handles into a predetermined range of jaw movement.

(1) Note. See definition of "ACTUATION" under subclass 300.

(2) Note. First, second or third class levers are not here considered to be converting means. For example, a nut-cracker or tweezer type of tool otherwise falling within the scope of the definition of subclass 300 is not here classified, but is to be found either in subclass 300 or in other subclasses below on the basis of other features.

(3) Note. For jaw adjustment mechanisms, see subclasses 385+.

(4) Note. See definition of "ADJUSTMENT" under subclass 300.

(5) Note. See definition of "RANGE" under subclass 300.
