DEFINITION

Classification: 269/104

(under subclass 86) Device including: (A) two or more jaw* couples spatially related so that a line between, and generally normal to, coacting gripping surfaces of one jaw couple is not parallel to a corresponding line of another jaw couple; and (B) each of the couples contacts either portions of the same workpiece or plural abutting workpieces.

(1) Note. This subclass does not include patents for holders with plural coacting jaws unless said jaws are adjusted* or actuated* in groups of two (i.e., in couples).

(2) Note. In regard to this and indented subclasses from subclass 105 through subclass 117, no effort has been made to cross-reference down from these subclasses to the indented subclasses running from subclass 118 through subclass 125, as the vast majority of the patents, in the higher group of subclasses, have at least one or more claims drawn to the subject matter of one or more of the subclasses positioned in the lower placed group of subclasses. Therefore, to be complete, any search involving one or more of subclasses from 118 through 125 should include a search of appropriate subclasses in the group running from subclass 104 through subclass 117 inclusive.

(3) Note. A patent claiming subject matter included within the above definition, and including a disclosure that provides for only two jaw couples with a single adjustment means (subclasses 165+) for positioning one couple and a single actuating* means (subclasses 216+) for positioning the other couple, will remain in this subclass. If either of the above jaw couples is disclosed as having plural positioning means, see the subclasses indented under subclass 109.

(4) Note. See (1) Note under subclass 111.
