DEFINITION

Classification: 30/194

(under subclass 173) Implements in which the blades have edges which move past and in substantial contact with each other to perform the cutting operation.

(1) Note. For combined nippers and shears and combined shears and knife, see this class, subclasses 145 and 146.

(2) Note. Many patents in this class, subclass 109, cut by a shearing action and search should be continued there.

(3) Note. Many patents in Class 81, Tools, subclasses 52+ and 300+ have structure similar to this group in so far as the operating mechanism is concerned, and search for the operating mechanism should be continued there.

(4) Note. Search this class, subclasses 29, 43, 120, 131, and 428.

(5) Note. For shears adapted for use on portions of the human body, see Class 606, Surgery, subclasses 174+, for shear cutting devices used on human or other animal body portions.

SEE OR SEARCH CLASS 81, Tools, particularly

300+, for tool-jaw(s) positioned by relatively movable plural handles (e.g., pliers), and see (3) Note above.
