DEFINITION

Classification: 72/312

With interrelated clamp closer and tool mover:

(under subclass 293) Subject matter wherein means to move one or move of said clamp jaws or surface elements to effective (i.e., work-gripping) positions, cooperates significantly with the means to move said movable instrumentality.

(1) Note. Self-actuated, or camming-type clamps have no "actuating means" other than the work itself, hence, are not placeable in this subclass.

(2) Note. The cooperation characteristic of this subclass may be an interlock (e.g., to prevent release of work while a tool is in motion), or a timing effect, or actual joint, or interconnected drive means for clamp closer and tool mover.
