DEFINITION

Classification: 123/163

The form of construction of the stationary electrode designed for use with and to form a part of a sparking device including relatively fixed and movable electrodes, as in the preceding make-and-break subclasses, such stationary electrodes being ordinarily capable of use with and as forming a part of any sparking device which includes fixed and movable electrodes.

(1) Note. It is intended that patents classifiable in other make-and-break subclasses, but which disclose specific stationary-electrode structure shall appear in this subclass as cross-references. Inasmuch, however, as all make-and-break sparking devices necessarily include a stationary electrode, a search involving stationary-electrode structures may sometimes extend to all make-and-break subclasses.
