Class 431
COMBUSTION
Class Definition:
This is the residual class for processes of combustion or
combustion starting, and for apparatus peculiarly adapted to
burn or ignite materials.
(1) Note. A fuel discharge nozzle is a subcombination of
basic subject matter of this class if it is specialized for
use in combustion solely (1) by discrete means transmitting
flame between distinct fuel discharge areas; (2) by flashback
preventing or controlling structure (3) by an incandescing
component; (4) by means maintaining a reigniting flame; or
(5) by flame enclosing, protecting or stabilizing structure.
(2) Note. Patents issued prior to 1940 have not in all
instances been classified by their claimed disclosure so the
placement of these patents does not necessarily indicate
lines of classification.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
See References To Other Classes, below, for information about
lines with other classes.

SEE OR SEARCH CLASS:
44, Fuel and Related Compositions, 507 for a match
structure; subclass 643 for a residual match striking
surface, per se; subclasses 530+ for fuel product of defined
shape or structure; and subclasses 542+ for fuel products
coated or impregnated for easier ignition.
48, Gas: Heating and Illuminating, appropriate subclass, for
an apparatus or process for the manufacture, purification,
mixing, distribution or storage of heating or illuminating
gas without combustion thereof. Also, when a portion of the
generated gas is burned to generate the gas and another
portion of the generated gas is purified, fixed or stored,
classification is in Class 48.
60, Power Plants, 39.01 for a combustion product generator,
per se, or subcombination thereof peculiarly adapted for
power generation, or solely disclosed for such purpose; and
appropriate subclasses for a residual device producing
mechanical power or thrust from fuel.
102, Ammunition and Explosives, 283 for a shaped thermic or
explosive charge; subclasses 335+ for a device other than a
photos:graphic flash device burning a packaged charge
containing both fuel and oxidizer for display, amusement
flashlight or signal purposes, e.g., flare, etc.; subclasses
335+ for an explosive or thermic charge within a casing; and
subclasses 464+ for a fuse, primer or igniter for igniting a
thermic or explosive charge. See (1) Note of the class
definition of Class 102 for a statement of the types of
material used in the devices of this class.
110, Furnaces, appropriate subclass for process of burning
solid fuel even though the solid fuel be combined with a gas
or liquid fuel, the line between Classes 110 and 431 relative
to combustion apparatus is: Class 110 takes solid fuel
burners that have a feature specialized to the burning of
such fuel, e.g., a grate, solid fuel preparer or treater
other than a mere preheater, a slag or ash remover, a
mechanical feeder such as a conveyor, etc. Class 431 takes
gaseous and liquid fuel combustion apparatus and burners
utilizing a finely divided fuel dispersed in air in which the
mixture merely acts as a fluid fuel stream, even though it is
defined by terms such as solid fuel burner, fuel suspension
burner, etc. Class 431 also takes candles, jelled fuel
burners, magnesium strip burners and illuminating flash
devices of the combustion type. Combustion apparatus for or a
method of burning liquid waste material, however, is proper
in Class 110. Also, search Class 110 for the following
furnace elements, subcombinations or appurtenances: 119 for
spark arrestors; subclasses 145+ for spark and smoke
conductors; subclasses 147+ for draft regulators for a
furnace; subclasses 165+ for an ash receiving or handling
device; subclass 172 for a furnace front; subclasses 173+ for
a door specialized for use in a furnace; subclass 181 for a
casing or arch specialized for use in a furnace door;
subclasses 182.5+ for a conduit specialized to feeding air to
a furnace; subclass 184 for a metal smoke stack specialized
for use with a locomotive or portable boiler.
122, Liquid Heaters and Vaporizers, appropriate subclasses
for a heat generator, (e.g., fuel burner, etc.) specifically
related to a closed holder of liquid to be heated, or
combined with a specific closed liquid holder. However, when
the liquid heated is fed to the burner head of a burner
assembly and the closed chamber or conduit is merely an
element of the burner assembly, classification is in Class
431.
123, Internal-Combustion Engines, appropriate subclass for a
device specialized to the production of power in which fuel
is burned in an expansible chamber.
126, Stoves and Furnaces, for the apparatus for the
application of heat, and for the stove and furnace elements
specifically provided for in the various subclasses; see
particularly 144 for a firepot or lining, subclasses 285+
for a damper, and subclasses 307+ for a stove pipe.
136, Batteries: Thermoelectric and Photoelectric, 217 for a
residual thermoelectric generator heated by a pilot burner.
137, Fluid Handling, appropriate subclass for a residual
fluid handling or feeding invention of general utility. The
recitation that a fuel is handled or that the invention
comprises a burner does not bar classification in Class 137
where no particulars of a flame holding element nor
significant relationship of a flame holder and fuel handler
based upon the combustibility of the fuel fed to the flame
holder is involved.
149, Explosive and Thermic Compositions or Charges,
appropriate subclass for an explosive or thermic composition,
or charge, e.g., match composition, etc.
206, Special Receptacle or Package, 85 for a tobacco
container with an igniter for said content and subclasses 96+
for a match packet, container or holder.
219, Electric Heating, 260 for an incandescent type of
electrically operated igniter, per se.
221, Article Dispensing, 136 for an article dispenser
combined with an ignition means.
236, Automatic Temperature and Humidity Regulation,
appropriate subclass for a control system regulating the
temperature of a chamber or material where no more of the
structure of the means supplying or removing heat is included
than is necessary to bring out its relationship to the
control system. It is noted that for Class 236 an igniter,
flame sensor or pilot burner is a part of the control
structure rather than of the controlled temperature modifying
burner. It is also noted that a residual apparatus
specialized to combustion and having either a broad or
specific burner is classified in Class 431 where the
operation of the temperature modifying burner is simply
initiated or terminated by a broad "off and on" thermostat
sensing and responding to the temperature of the chamber or
material heated by the burner.
239, Fluid Sprinkling, Spraying, and Diffusing, appropriate
subclass for subject matter relating to the emission from a
fluid handling system in modified flow, of fluid or slurry,
and for the emitter member, per se. An indication that a fuel
is handled or that the emitted material is burned (e.g.,
named welding torch, etc.) does not bar classification in
Class 239 in the absence of a feature or structure dependent
upon the combustion or combustibility of the fuel
specializing the invention to combustion.
The structure listed in Notes to the Class Definition (1)
Note above and the following features or elements are among
those that distinguish a specialized fuel discharger
classifiable in Class 431 from a Class 239 structure: (1) A
device for starting combustion at the discharger such as a
pilot or igniter even nominally recited. (2) A sensor of
combustion heat in, or burner flame at the discharger,
controlling feed to the discharger.
313, Electric Lamp and Discharge Devices, appropriate
subclass for an air gap discharge device (e.g., spark plug
etc.), per se.
361, Electricity: Electrical Systems and Devices, 247 for a
residual electrical igniting system.
362, Illumination, appropriate subclasses for an illumination
device comprising a light source, e.g., a burner etc.,
combined (1) with a device that encloses the light source and
transmits the light therefrom or (2) with a light
distributor. However, patents issued prior to 1940, having a
conventionally shown light transmitting or distributing
device and specific burner structure have been placed in the
appropriate burner subclass in Class 431.
417, Pumps, 73, for a pumping system operated by combustion
displacement of the liquid and appropriate subclass for a
pumping system that may handle fuel where combustion of the
material handled is not involved.
422, Chemical Apparatus and Process Disinfecting,
Deodorizing, Preserving, or Sterilizing, appropriate
subclasses for apparatus for generating a treating agent by
burning a combustible material, a combustion or reaction
device for purifying a gas, or with means for recovering,
mixing, separating, or otherwise handling as a product
material formed in the device or residual chemical
apparatus.
423, Chemistry of Inorganic Compounds, appropriate subclass,
for inorganic compounds and nonmetallic elements including
their manufacture by chemical reaction, and note especially
212 for exhaust gas purification or separation.
429, Chemistry: Electrical Current Producing Apparatus,
Product, and Process, 12 for a battery generating current by
feeding a gas into a cell to react with fluids in the cell,
(e.g., fuel cell, etc.).
432, Heating, appropriate subclass, for a residual method or
apparatus for generating heat and applying it to materials.
588, Hazardous or Toxic Waste Destruction or Containment,
appropriate subclasses for the methods of combustion of
hazardous or toxic waste, from any source where a useful
product is not produced or obtained.
