DEFINITION

Classification: 313/267

(under subclass 243) Discharge devices having means for supporting and/or spacing a plurality of rod-like electrodes.

(1) Note. This subclass includes arc lamps and similar discharge devices which are provided with a plurality of rod-like electrodes and which are usually intended to have the arc or other discharge maintained between the ends of the electrodes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

238, for patents claiming the structure for supporting only a single rod electrode of a discharge device.

325, for patents claiming electric discharge devices having rod-like electrodes where no significant supporting and/or spacing structure is claimed.

357, and the subclasses specified in the notes to the definition of that subclass for the structure of rod electrodes, per se. SEE OR SEARCH CLASS

314, Electric Lamp and Discharge Devices, Consumable Electrodes, appropriate subclasses for discharge devices of the consumable electrode type (e.g., arc lamps and similar devices having means for feeding the electrodes together as they are consumed) which have supporting and/or spacing structure for a plurality of rod-like electrodes.
