(under the class definition) Implement provided with means for transferring thermal energy to the coating material carried by the implement prior to its application to the surface.
(1) Note. For placement in this subclass a patent must contain an express teaching of a heat imparting means whereby heat is either (a) generated within the implement, as by a burner or resistance heater, or (b) conducted by the implement from an outside source, e.g., body (hand) heat of the user.
(2) Note. A patent claiming structure adapted to utilize heat from a user's hand to induce or cause flow of material, by thermal expansion of said material in an unvented reservoir, for the purpose of coating a work surface will be placed in this subclass.
(3) Note. A patent for a device for heating and applying sealing wax is acceptable for this class and subclass only when the disclosure makes it clear that the device includes a tool which contacts the work for applying or spreading the coating material. A patent for a device for heating and dispensing sealing wax onto a surface, without contact between the device and the surface, will be placed in the Dispensing class (see Search Class note below).
SEE OR SEARCH THIS CLASS, SUBCLASS:
12, for an implement whose coating material is melted by transfer of heat from a workpiece.
225+, for a bifurcate tool implement including means for retaining coating material which has flowed out of the reservoir because of inadvertent heating. SEE OR SEARCH CLASS
118, Coating Apparatus,
620+, for coating apparatus including means for treating the coating material with electrical or radiant energy, and especially subclasses 641+ for such an apparatus including radiant heating; and subclass 271, for an apparatus including an applicator coated or impregnated with normally solid material which requires the application of heat to render it fluent; and see the Search Notes reference to Class 118 in the class definition of this class (401)
184, Lubrication,
98+, for a lubricating device in which solid or semi-solid lubricant is adapted to be heated by the friction of bearing parts and thereby melted.
222, Dispensing,
113, or 146.1, for a dispenser combined with a heater for melting sealing wax and permitting it to flow to a surface; and see (3) Note, above.
228, Metal Fusion Bonding,
51+, for a similar implement, limited by disclosure to coating a metal surface with molten metal.
425, Plastic Article or Earthenware Shaping or Treating: Apparatus,
110+, for a hand-manipulable sealing wax applier including (1) means to melt the wax and apply it to a surface and (2) a seal for making an impression on the applied wax.
