DEFINITION

Classification: 219/257

(under subclass 256) Subject matter including means whereby the completion or interruption of an electric current to an external source of current at the beginning or end of the use of the iron is accomplished automatically.

(1) Note. The term "automatic" is construed to include the operation of a switch in the circuit of the electrical heating means by a switch operator which is motivated by the grasping of the handle and the guiding of the soleplate type iron in the normal manner of using the iron.

(2) Note. The line between Class 200, Electricity: Circuit Makers and Breakers and this class is: where an electric iron is claimed by name only with no inclusion of a specific electric heater and just enough structure of the iron to support the switch, the patent shall be classified in Class 200, appropriate subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

250+, for voltage or current control means for the iron responsive to variations in the voltage or current delivered to the heating means or thermal conditions of the iron which may involve connection and/or disconnection of the heater from a source while in use.

489, for combined manual and automatic regulating or control means for the current to an electric heater in general. 490+, for automatic control means of the voltage or current to an electrical heater in general.

509+, for automatically operated switches for connecting and/or disconnecting electrical heating means in general from a power supply.
