DEFINITION

Classification: 219/229

(under subclass 227) Subject matter wherein the hand held tools or instruments have electrically heated tips rather than heated expansive areas forming the working area of the tool or instrument.

(2) Note. Hand held electrically heated burning in tools for filling in dents or scratches in furniture in general are placed here. However, Class 425, Plastic Article or Earthenware Shaping or Treating: Apparatus, subclass 12 provides for such tools which will fill or mold to a predetermined depth or dimension.

(3) Note. The subcombination of a tip and its heater of a tip-type hand held or manipulated tool or instrument is classified in the subclass containing the complete tool or instrument.
