DEFINITION

Classification: 269/165

(under subclass 86) Device including adjustment* means to initially position a jaw or jaws.

(1) Note. The adjustment means is often referred to as a "quick adjust", "quick acting means" or "rapid set means" for the purpose of fixing an approximate jaw position with respect to the work to be held, after which a gripping force is applied to further move the jaw against the work. Such further movement, where the gripping force is applied by means not encompassed by the definition of adjustments, need by merely infinitesimal to be considered actuating* movement.

(2) Note. The adjustment positioning of (1) Note, above, is generally a simple sliding, pivoting or changing of a jaw(s) effected by an operative grasping said jaw, or a portion thereof or a member attached thereto, and imparting all spacial repositioning to said jaw by congruent movements of his hand.

(3) Note. Included in this subclass are patents to a holder with an insert adjustment-lock* means which means comprises one or more blocks positionable between structural elements constituting the means for jaw adjustment so as to relatively immobilize said elements. A wedge or cam-like insert, without means to apply force or bias to further seat the wedge (or rock the cam-like element), used to effect adjustment-lock is one form of such block.

(4) Note. A patent claiming means which provides for both adjustment and actuation, and not encompassed by the definitions of subclasses higher in the class schedule, will be placed here (subclasses 165+) on the basis of the adjustment feature and cross-referenced to the appropriate actuation subclasses (216+).
