SECTION I - CLASS DEFINITION
This class includes all those devices commonly known as electric heaters, electric-heating metal working apparatus, electrically-heated tools and instruments. Processes are classified with the apparatus unless otherwise indicated by the subclass title.
This is the generic class for electric heating devices, per se. Devices and systems equipped with electric heating means in which the electric heating means is combined with or includes specific other art structure whereby the heated material is withdrawn, stored or otherwise utilized will be classified in the appropriate other art class to which it pertains and cross referenced back to Class 219.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
An example of other classes as mentioned above in the Class Definition is Class 122, Liquid Heaters and Vaporizers in which such terms as steam dome, super heaters, steam separators, condensers, traps, etc., are considered to be art structure over and beyond the mere heating of a liquid and comprising specific means for further storing or utilizing the liquid or vapor resulting from a heating step and sufficient to exclude the claimed subject matter from this class.
The liquid heaters to be found in this class, subclasses 281+ are very similar to those classified in Class 122 and in Class 126, subclasses 344+. The general line to be followed in distinguishing between this and those classes is as follows: Where the claims recite specific electrical means for heating a liquid only and the end result recited is a heated liquid only and no further means is claimed for withdrawing the liquid for further use the device will be considered a liquid heater for this class. For an understanding of the lines between Classes 122 and 126 consult the class definitions and the notes thereunder.
