397
.~.~ On actuated tool
DEFINITION
Classification: 72/397
On actuated tool:
(under subclass 396) Device wherein said relatively distortable or displaceable part or said distinct member is attached to or mounted on a driven element of a tool couple.
(1) Note. The yieldable tool or face portion is thus driven by or with the active tool of a tool couple (see Figure B of the diagram accompanying subclass 398).
(2) Note. For an indirectly driven tool (i.e., moved against work by force derived from another portion of the work), see the floating mandrel combination in subclass 398, below. A floating mandrel is an active tool, although indirectly driven. Compare the passive indirectly driven tools of subclass 396 above.
(3) Note. The yieldable tool or member may constitute a "blank-holder" for frictionally restraining movement of work during deformation by a tool couple. Any disclosure of work slippage or flow relative to a blank-holder or restraining element bars the combination from placement in the nondeforming work-gripping clamp area, see subclasses 293+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
293+, for a positively gripping, nondeforming clamp element associated with a driven tool.
350+, for a yieldable blank-holder associated with a cup- or shell-drawing device. 465.1+, for flexible or yieldable tool structure
