DEFINITION

Classification: 83/401

(under the class definition) Apparatus including (a) dynamic means to effect movement of the work with respect to the zone of the claimed cutter, or (b) a device associated and moving with the work to hold or support the work and facilitate movement thereof with respect to such zone.

(0.5) Note. An extension of a plane from the outer surface of a cutting edge of a cutter closest to the work will be referred to as a "plane of cut" or "cutting plane".

(1) Note. This and indented subclasses are the residual subclasses for the placement of a patent in which a work-conveying means is claimed or clearly inferred from the context of the claim and in which a cutter is claimed. A patents in which work movement is effected by an operator grasping the work itself and pushing or pulling such work without correspondingly moving the work-associated device is excluded from this and the indented subclasses (401+).

(2) Note. The work-moving means may comprise any structure by which the work is moved relative to a cutting zone even though the structure itself may be advanced manually. Examples of such structure are a moving table, a pusher, a belt, an air-blast nozzle, etc.

(3) Note. For the relationship of this group of subclasses to other work-handling classes, see the Class Definition of this class (83), section II, Lines With Other Classes, subsection B, Relationship to Material Handling Classes.

SEE OR SEARCH THIS CLASS, SUBCLASS: 202+, for a cutting apparatus in which work is moved, stopped, and cut during the dwell in work movement.

284+, for a device which cuts moving work by a transverse cutter moving with the work during cutting.

350+, for a cutting apparatus including a tool which approaches the work and recedes therefrom in a cutting stroke which is otherwise timed or synchronized with respect to work movement.

469+, and 651+, as appropriate, for a patent in which a cutter is claimed and no work-moving means is claimed, even though it is apparent that the work must move to be cut.

471+, for a cutting apparatus including a relatively immovable work-supporting table, and a rotatable disc blade cutter.

648+, for a cutting apparatus in which work movement is effected by an operator grasping the work itself and pushing or pulling such work relative to a work support.

198, Conveyors: Power-Driven, for a power driven conveyor in which no tool is claimed significantly, and see (3) Note above. Search

343.1+, and 375+ for a conveyor having means for orienting the conveyed load relative to the conveyor.

226, Advancing Material of Indeterminate Length, for means to move work, generally, without recognition of both the leading and trailing ends thereof.

269, Work Holders, appropriate subclasses and Section II, Lines With Other Classes, paragraph B, of that class for the line between this class and Class 269.

271, Sheet Feeding or Delivering, for means to move a relatively thin, flat workpiece of finite dimensions. 414, Material or Article Handling, for means to move an individually recognized workpiece, generally.
