DEFINITION

Classification: 451/442

ACCESSORY:

(under the class definition) Apparatus intended to be used with and to augment the operation of a device under the class definition.

(1) Note. Included herein is an apparatus or part that is a part of or is separate from the device under the class definition, unless provided for in a preceding subclass.

(2) Note. This subclass takes an abradant-resist (i.e., mask or stencil defining a work area and protecting underlying surface portions of the workpiece). However, a nominal recitation (e.g., "stencil sheet designed for cutting") followed by a definition of a miscellaneous product of a Class 427 type of coating operation, or of a rubber chemistry material composition, or of a stock material blank, would each be deemed to recite insufficient abradant-resist structure for placement in this subclass and will be found in that class taking the defined subject matter.
