(under subclass 86) Device including two or more jaw* couples.
(1) Note. Patent placement here requires that the claimed holder jaws coact in pairs, that is, each jaw is movable relative to another particular jaw, whether or not each pair engages the same workpiece.
(2) Note. Two or more work contacting elements, each of which is separately movable, (i.e., adjusted* and/or actuated*), which coact with a single member to grip a workpiece(s), are considered to be plural jaws and are specifically set out in subclass 154 below.
(3) Note. This subclass is residual, in the workholder art, for patents claiming plural jaw pairs, which jaw pairs are not encompassed by the definitions of superior subclasses in the class schedule.
