Class 239
FLUID SPRINKLING, SPRAYING, AND DIFFUSING
Class Definition:
A. SPRAYING AND SPRINKLING
This is the general class for claims pertaining to the
spraying, sprinkling, or scattering of fluids or fluent
solids either in the form of slurries or as dry material,
over an extended area on a surface. The class includes
processes and apparatus, not provided for in some more
specialized class, for ejecting fluents and slurries by
slinging, sloshing, centrifugally throwing, overflowing, and
projecting such materials in the form of fog, mist, droplets,
spray, sprinkle or a modified stream in a general haphazard
or broadcasting manner upon the immediate vicinity of
operation or environment, upon a surface to be treated. The
surface may be of any shape or form and the sprinkling,
spraying, or scattering may be for any purpose, for example,
a street to be flushed or oiled, a field or lawn to be
irrigated by a lawn sprinkler, hose, nozzle, or overhead
irrigating system or to be fertilized or to be seeded, a tree
or other plant to be sprayed or dusted for some plant
husbandry reason or for destroying insects, etc.; however,
any claim reciting a specialized relation between the
sprinkling, spraying, or scattering means and the surface,
work or environment being treated is excluded from this
class. Some form of modified flow, either by way of discharge
characteristic, (e.g., droplet size, or degree of
atomization, etc.) is required.
B. WEATHER CONTROL OR MODIFICATION
This class also takes methods for causing or inhibiting
changes in atmospheric moisture conditions not elsewhere
classified as by precipitating, dissipating, or inhibiting
atmospheric moisture (rain, fog, frost, or snow) or inducing
fog or like, and apparatus for precipitating atmospheric
moisture if not classifiable in some other class on the basis
of the claimed proximate functions.
C. DIFFUSERS
This class also takes methods and apparatus for disposing or
disseminating a liquid or solid into the ambient air by
unhurried evaporation or sublimation, the material being
supplied to or supported by a holder, with or without
controlled dripping of the substance through the ambient air
or being fed usually to an absorbent material from whose
surface evaporation takes place.
D. FOUNTAINS
This class also provides the locus for patents including
steps or means for ejecting liquids into the air as a stream
or spray to serve an ornamental or decorative function or for
directing a bubble or stream generally upwardly for drinking
purposes especially where the fluid conducting or ejecting
member is associated with a stand, pedestal, or catch basin
for overflow or waste.
E. DRINKING TUBES AND STRAWS
This class also provides the generic repository for portable
drinking tubes and straws, per se, including those which are
sipped through by placing one end of the tube in the mouth
while the other end thereof is in the fluid within a holder,
and also for those which are held in a flowing stream, e.g.,
juxtaposed a faucet, and redirect the fluid to the mouth.
F. DRY PULVERULENT MATERIAL
This class provides for the combination of a container or
similar receptacle for holding a supply of dry material and a
means to strew or scatter such material in the dry form over
an extended area on a surface; a nozzle, per se, disclosed
for scattering or strewing a dry powder is properly
classified in this class only if the claimed structure is
capable of use with a fluid.
Except as provided in the above paragraph, this is also the
class for discharging or scattering a fluent material only if
there is fluid sprinkling, spraying, or diffusing of the type
specified in A. Spraying and Sprinkling, above, no matter in
which order the fluent is discharged in relation to the fluid
and with no regard as to whether or not one material reaches
the surface to be contacted after the other has already been
deposited thereon.
G. TERMINAL FLUID HANDLING ELEMENTS AND ORIFICE SHAPES
This class also provides the residual home for fluid
discharging or ejecting members, per se, claimed as terminal
members, i.e., members which render the final influence or
point of control upon a fluid during its projection from the
fluid system to discharge into the atmosphere, or through the
air to the environment and not having such additional
features which restrict the use thereof to some special art
or other classification. Such nozzle, distributor, apertured
pipe, orifice shape, rose, etc., must serve to modify flow of
the fluid as it leaves the element. Terminal fluid handling
elements, orifice shapes, ejecting or egress means for this
class include:
(1) Outlet means which effect modification of the emitted
stream to cause lateral compression or expansion thereof,
such as would not occur in a mere abruptly terminated flow
means (e.g., a pipe cut off at its end);
(2) means within, proximate to, or at the end of the flow
line to cause the emitted stream to become more turbulent, or
to be reduced in turbulence tending to assume a smooth or
laminar flow, or to be redirected and dispersed;
(3) means to control droplet size, to restrict flow to
increase pressure, or to alter discharge coverage, of the
emitted stream.
Examples of means to accomplish the above are orifice shapes,
spray heads, and the like; weir or drip type discharge, and
other outlet means with such added features as whirlers,
deflectors, rotation controllers, interiorly placed guides
and distributors and systems including aspirating nozzles.
In order to be properly classified in this class, a claim
must include a distributor or nozzle means more specifically
than by name only (except as hereinafter provided with
respect to Class 137). A claim which recites an ejecting,
egress, or distributor means by name only is properly
classified in this class only if the claim also includes:
(a) a coupling means for adjustably securing such terminal
means to a support, or an articulated coupling means mounted
on a support, if the disclosed purpose of the coupling is to
reorient the terminal means relative to the support;
(b) special mounting or support means for purposes of
continuous motion during discharge or emission of the stream,
or means for directing such terminal means along a path of
traverse, where the means for moving and the means for
directing are disclosed for sprinkling or spraying;
(c) two or more such nominally recited terminal means and
some suggestion of arrangement relative to each other or to a
support, e.g., along a pipe, at the ends of a support, etc.
(d) a fluid handling system disclosed for sprinkling or
spraying, if no better basis exists for classification in
either Class 137 or Class 222. See References to Other
Classes, below;
(e) a fluid handling system disclosed for spraying and
including an aspirating nozzle where discharge is by
aspiration, or feedback control, e.g., flow regulation as a
result of discharge or for control of discharge, or some
other provision as otherwise defined hereinabove; or
(f) a container for nonfluid material and it is clear that
the broadly recited ejecting, egress or distributor means is
an element which moves relatively to a fixed support, such as
a rotating scatterer. See (3) Note in subclass 650.
Certain structures, for example, unitary plural outlet means,
are considered to be terminal members, per se; therefore the
following or the like are considered to involve more than
mere named or nominal terminal means, and if such or similar
language is recited in a claim, affords basis for
classification in this class, unless reason exists for
exclusion in view of the class lines set out below:
A pipe with a restricted outlet; a flexible, rigid or
elongated nozzle; a spray gun; a rose; a shower head.
Similarly, a cutting or welding torch, a burner, a fuel
injector recited as such is classified in this class if it is
clear that the terminal member or tip is included in such
recitation, and not just the support for such terminal member
or tip.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A. ART DEVICE COMBINATIONS AND SUPPORT
This class takes (1) means not provided for in any other
class to support a distributor, terminal outlet member or a
portion of the fluid supply system leading to the distributor
or terminal outlet member on, in relation to, or from, a
device which ordinarily performs a function other than that
of mere support, provided the claimed relationship is no more
than that required for support or normal operation of the
fluid system or its terminal outlet member, (2) the subject
matter of this class combined with an art device in which
there in no special relationship claimed between the spray
device and the art device.
Thus, a treating chamber nominally set forth as supporting a
distributor or terminal outlet members therein is subject
matter for this class as long as no special relationship to
the walls thereof, for example, is required.
Accordingly, this Class 239 will take patents directed to the
combination of a tank or treating chamber by name only and a
distributor.
B. FLEXIBLE FLOW LINE STORAGE OR RETRIEVAL
This class provides for flexible flow line storage for nonuse
housing or support including retrieval means except as
provided hereinbelow:
Class 251, Valves and Valve Actuation, takes only the valve
plus the actuator and support for the valve in a system
disclosed for this purpose.
Class 285, Pipe Joints or Couplings, takes combinations of a
pipe joint or coupling and a support therefor which support
may be a reel or rack by name. Only so much flow line
necessary for the coupling or joining modification may be
included.
Class 242, Winding, Tensioning, or Guiding, takes only
combinations of reel means or the like (storage on sheaves)
and supporting means or reels, per se, with or without the
flexible conduit or with or without retrieval means.
Inclusion of a fluid handling element not necessary to the
reeling, unreeling or reel support, is sufficient to exclude
such patent from the class.
Class 248, Supports, is in the same relative position in this
regard with the fluid handling classes as is Class 242
explained above, taking only support or storage means for the
flexible conduit or named nozzle. If a fluid handling element
is included, such element must be necessary for the support
function.
Class 137, Fluid Handling, takes combinations involving fluid
handling means too much for the above named classes and
wherein nozzles or outlet means for spraying are not included
and not otherwise including features of dispensing recognized
by Class 222.
Class 92, Expansible Chamber Devices, takes combinations
involving an expansible chamber device and storage or
retrieval means for a conduit supply working fluid to or from
the expansible chamber and wherein nozzle or outlet means for
spraying are not included and not otherwise including
features of dispensing recognized by Class 222.
Class 222, Dispensing, takes the combination with storage or
nonuse support means for the function of this section of a
dispensing outlet or nozzle, the supply tank and a control
means for the flow or delivery of fluid; or a tank, discharge
assistant and dispensing outlet. Systems including broadly
recited nozzles for spraying having dispensing features
recognized by Class 222 will not mitigate against
classification in this class.
Class 239, Fluid Sprinkling, Spraying, and Diffusing, takes
combinations of the above named elements if there is included
some detail of a spraying or sprinkling nozzle or outlet
element. A nozzle in name only except as otherwise indicated
(see Glossary) is classified as set forth above.
As a general rule, Class 239 provides a place for the entire
combination of hose, hose storage and a specific spraying
nozzle. For the subcombination of the hose, storage means and
fluid handling, see Class 137; for the subcombination of a
valve and support therefor, see Class 251; for the
subcombination of a pipe joint or coupling and a support
therefor, see Class 285; for a reel only and the hose (no
additional flow conducting elements) see Class 242; for a
hose support (no additional flow handling elements) see Class
248; for a tank, pump and broad outlet or nozzle, or for a
supply tank, flow control and a broad outlet or nozzle, see
Class 222.

Class 40, Card, Picture, or Sign Exhibiting, subclass 213
for smoke producing apparatus and systems limited to
skywriting.
Class 43, Fishing, Trapping, and Vermin Destroying, for
smoke or fog making apparatus where the sole disclosed use
for the resulting fog or smoke is as an insecticide (except
where a liquid is mechanically atomized), including such
where vaporization of a liquid insecticide is involved.
Class 47, Plant Husbandry, subclass 2 for methods and
devices for preventing the freezing of trees and plants and
their fruit not elsewhere provided for (such as misting).
Class 102, Ammunition and Explosives, subclass 334 for
apparatus for and methods of smoke generating (i.e., causing
vapor, cloud, etc., to be formed by a burning), subclasses
335+ for pyrotechnics apparatus and corresponding methods
designed to produce smoke, light, heat, and/or noise (e.g.,
fireworks display, amusement, flash photo, signal),
subclasses 367+ for apparatus for or methods of using an
explosion to cause a liquid, solid, or gas to be scattered or
spread about in the form of a mist, vapor, particles, or gas
(e.g., noxious or incapacitating, plant, insect, animal,
foliage, biological warfare/chemical warfare).
Class 109, Safes, Bank Protection, or a Related Device,
subclasses 29+ for devices of the Class combined with means
for releasing, generating and/or distributing gas, smoke,
vapors and/or liquids either manually, automatically upon
attack, or automatically in case of fire, which fluent
material is normally, but not necessarily, toxic,
noncombustible, or incapacitating and may normally, but not
necessarily, be used to repel attacks and/or put out,
prevent, or impede the action of a fire, and this includes
devices relating to jails, where the purposes of this
subclass are also present.
Class 126, Stoves and Furnaces, subclass 59.5 for portable
devices for generating heat or smoke for protecting orchards
from frost (e.g., smudge pots).
Class 222, Dispensing, and 239, Fluid Sprinkling, Spraying,
and Diffusing, depending upon nozzle detail, when a specific
container or supply holding means is claimed to define a
package. Class 424, Drug, Bio-Affecting and Body Treating
Compositions, takes aerosol compositions there specifically
provided. Classification is with appropriate class for
compositions should a container or supply holding means be
broadly included to define a package. Classification is with
Classes 222, Dispensing, and 239, Fluid Sprinkling, Spraying,
and Diffusing, depending upon nozzle detail, when a specific
container or supply holding means is claimed to define a
package.
Class 239, Fluid Sprinkling, Spraying, and Diffusing,
provides for mere mechanical atomization, not provided for in
some more specialized class. This class also takes methods
for causing or inhibiting changes in atmospheric moisture
conditions not elsewhere classified as by precipitating,
dissipating, or inhibiting atmospheric moisture (rain, fog,
frost, or snow) or inducing fog or like, and apparatus for
precipitating atmospheric moisture if not classifiable in
some other class on the basis of the claimed proximate
functions, see subclasses 14.1+ for apparatus for weather
control, such as snow making.
Class 261, Gas and Liquid Contact Apparatus, subclasses 75+
for devices specially adapted to produce an intimate contact
between gases and liquids (especially 78.1+ for atomizer).

Class 426, Food or Edible Material: Processes,
Compositions, and Products, subclass 116 for packaged or
wrapped product having utility for dispensing or serving an
aerosol, subclass 235 for application of a gas, mist, smoke,
or vapor to a food material under the influence of electrical

such systems or agents, when generically claimed or when
there is no hierarchically superior provision in the USPC for
the specifically claimed art. See the Search Class notes
therein for various locations of compositions, processes, and
apparatus relating to colloid systems.
D. LATHER MAKERS
This subject matter involves the addition of air or gas to
solution to produce lather.
Class 422, Chemical Apparatus and Process Disinfecting,
Deodorizing, Preserving, or Sterilizing, provides for holders
for dissolving of solids (wherein the holder as disclosed is
incapable of retaining a liquid) where the dissolving takes
place in the holder and may thereafter be added to a stream,
the handling of liquids being restricted to the purpose of
dissolving.
Class 137, Fluid Handling, includes apparatus under the class
definition for fluid handling plus means for holding a solid,
flaky, or pulverized material to be dissolved or entrained
and also provides means for adding a liquid to a liquid and
with respect to each such handling relationship is entirely
residual.
Class 222, Dispensing, provides for a holder or supply means
for material to be dissolved, mixed, or entrained, in a
liquid, or already in solution with additional means to mix
ambient air with the solution including a spray, nozzle or
outlet by name only, a dispensing outlet, and Class 222 type
discharge means (and not the mere production of lather and
the swelling or overflowing discharge resulting therefrom for
which see Class 261), or trap chamber or metering chamber
type control, outlet guide or movable material outlet guide,
but not including a clear disclosure relating to the
projection or forcibly expelling the lather or foam for
distribution.
Class 261, Gas and Liquid Contact Apparatus, provides for
specific gas and liquid contact apparatus, (and in this
connection (dissolvers) makes no provision for contacting a
liquid and solid means for purposes of obtaining a solution)
to make lather with means to deliver the lather to a mere
outlet pipe or line unmodified as to valving or other flow
line characteristic recognized by Class 222 except to further
effect the exchange of properties of the materials being
contacted prior to discharge.
Class 239, Fluid Sprinkling, Spraying, and Diffusing,
provides for combinations of the above considered subject
matter having a modified discharging nozzle or otherwise
limited projecting means coming within the class definition
of spraying.
E. MORTAR MIXING AND PROJECTING - PARGETING
Class 366, Agitating, subclasses 1+ for processes and
apparatus for batch mixing of mortar, asphaltic and hydraulic
cement, concrete and the like, including projection thereof
by spattering or pargeting devices or projection nozzles,
with or without specific nozzle structure or mixing by or
with fluids of the ingredients downstream of the hopper or
vessel, if the disclosure is specific to or includes mixing
mortar, plaster, or concrete ingredients (which as a general
rule comprise sand, gravel, lime, plaster or the like
lapideous material, etc.).
(1) Note. Processes and apparatus for projection or spraying
of resin type cements which require mixing just prior to or
at discharge, usually with a catalyst to cause solidification
or setting up, (e.g., epoxy resins), or comprising particular
nozzle structure of the type defined in Class 239, combined
with agitation or mixing of ingredients in the supply means,
provided the ingredients are not those which make up plaster
or concrete mixtures (as defined in the preceding paragraph),
are classified in Class 239.
Class 52, Static Structures (e.g., Buildings), subclass 749
for miscellaneous machines and implements used in the
construction of buildings, and see the search notes for other
classes and subclasses having related apparatus.
F. PIPE COUPLINGS AND COUPLING TO SUPPORT
Class 285, Pipe Joints or Couplings, provides for couplings
adapted to be connected to a nozzle or in combination with a
nominal nozzle having no recited nozzle features on the
theory that a broadly recited nozzle constitutes no more than
a conduit. However, the patents have been placed in this
(239) class where the coupling is adjustably secured to a
support or where an articulated coupling is mounted on a
support and in each case, a nominal or specific nozzle is
claimed if the disclosed purpose of the coupling adjustment
is to re-orient the nozzle relative to the support. The
patents have also been placed in this (239) class where the
coupling, as claimed, is disposed between two serially
arranged portions of a single nozzle, each positively recited
as a nozzle portion, to form in effect an articulated nozzle.
Coupling parts formed integrally with a nominally recited
nozzle have been considered subject matter for Class 285
where the nozzle as claimed could be considered a mere pipe,
flow line or coupling section.
G. SLOW DIFFUSERS
Except as otherwise provided, this class (239) takes
apparatus for such purpose if more than a composition,
poison, disinfectant or the like is claimed, see, for
example, Classes 96, Gas Separation: Apparatus; 424, Drug,
Bio-Affecting and Body Treating Compositions; 422, Chemical
Apparatus and Process Disinfecting, Deodorizing, Preserving,
or Sterilizing. Class 422, Chemical Apparatus and Process
Disinfecting, Deodorizing, Preserving, or Sterilizing,
subclass 305 illustrates how that class is related to this
class (239) as combination to subcombination, respectively,
e.g., vapor or fume generation including mere heating of a
compound to drive off a fume to change a slow diffuser into
one which is forced.
With a disclosure of gas separation or humidity control (air
conditioning) Class 239 will take, as a slow diffuser, a pad,
filter or fibrous mass which is saturated or maintained
saturated with a diffusible liquid (water or volative
solvents) unless any of the following is included:
(1) claimed gas contacting means within the meaning of Class
261 (e.g., special flow arrangements through conduits or the
like), or
(2) claimed gas movement effecting means (e.g., pump or
fan).
Class 261 will take patents having the (1) or (2)
qualifications set out above if the filter, pad or mass is:
(a) continuously supplied with liquid, or (b) cyclically or
periodically moved through a liquid reservoir, or (c)
maintained wet by liquid applying means, or (d) moistened by
maintaining some part of a continuous wick type member
immersed in liquid.
Class 96 will take patents having the (1) or (2)
qualifications as set out above if the liquid supply means
described in the immediately preceding paragraph is not
included. An absorbent mass with oil or viscous fluid therein
or supplied thereto disclosed for gas separation, or a solid
or nonabsorbent sheet disclosed in a gas separating
environment is not classified in Class 239 under any
circumstances but is classifiable in either Class 96 or Class
261 depending on the nature of the liquid source. See also
Class 96, the class definition, under Search Class 261.

irrigation systems having ditches or subterranean irrigating
conduits with means to supply fertilizer or the like to the
irrigating water for discharge into the soil; subclass 1.7

thrust by use of a jet nozzle, and subclasses 204+ for the
combination of a jet nozzle and a pump, heating chamber, or
other means recited more specifically than by name only, for
imparting energy to the fluid stream to be discharged from
the nozzle, where the sole, specific, disclosure is to obtain
thrust as a result of the fluid discharge; however, the
combination of a nozzle and a means for imparting energy to
the fluid prior to discharge therefrom is not excluded from
Class 239, if the disclosure relates to sprinkling, spraying,
or diffusing the discharged fluid, even though propulsive
thrust is obtained therefrom. See also the Notes in Class
239, subclass 265.11.
83, Cutting, appropriate subclasses for apparatus comprising
a cutting means as defined therein, a container for nonfluid
material and discharging to the cutting means, and a means
discharging the product of the cutting means where the claim
is silent as to structure for strewing or scattering the
product.

apparatus for gas separation. Class 239, subclass 34 is the
generic subclass for slow diffusers and for desorption by
mere ambient air of a liquid saturated sorbent.

315, for beverage infusers in which liquid is sprayed or
distributed over infusible material, and subclasses 345+ for
cooking apparatus combined with means for basting food with a
liquid, or in general Class 99 has spray arrangements for
contacting or treating food; however, Class 239 will take
claims to spray apparatus where no special coaction or
cooperation is set forth as for example no work support or
work handling is claimed. Class 239 would not take for
example a tentacled tedder for distribution of fluids through
a harvested crop.
100, Presses, 73 for presses having means to add liquid
and/or steam to the material pressed.

prevented or discouraged wherein spray nozzles or discharge
means are related to the paths of entry, e.g., platform, cab,
steps, etc. Spray apparatus coming within the definition of
Class 239 and merely vehicle attached or carried will be
found in subclasses 172+ and other appropriate subclasses of
this (239) class.

fluid distributor under the definition of Class 239 which
produces a wave (sonic or supersonic) and which includes
structure (e.g., horn, resonance chamber) to amplify or

coating by spraying, and see the class definition of Class
118 for the line between Class 118 and this (239) class; and

fountains, and subclass 156 for antivermin treatment for
animals having some stock, restraining device or other
specialized cooperating means and not capable of general
use.
122, Liquid Heaters and Vaporizers, appropriate subclasses,
for the combination of a burner or flame nozzle specifically
related to a closed liquid container.
123, Internal-Combustion Engines, appropriate subclasses,
particularly subclass 495 and 590+ for charge forming,
atomizing and mixing devices for combustibles claimed in
combination with significant internal combustion engine
structure. See this (239) class particularly subclasses 87
through 96 and 278 for appropriate combinations there
classified and see Lines With Other Classes, Art Device
Combinations and Support, above.
126, Stoves and Furnaces, 271.1 for weed destroyers and snow
and ice melters involving surface heaters and the blowing of
steam upon tracks for clearing tracks of snow.

subclasses for spray arrangements having means to manipulate
or support the work during spraying, or special relation to
the work being treated, e.g., hollow work cleaning, inverted
U-shaped spray frames for vehicle washing, special tank
relationships, etc. This (239) class takes spray means
subcombinations and combinations with tank by name only and
combinations wherein the tank as claimed is no more than a
mere support for the spray means and see "Lines with Other
Classes, Art Device Combinations and Support" above.
137, Fluid Handling, appropriate subclasses. This class is
residual with respect to the fluid handling classes and does
not take the combination of a fluid handling apparatus and a
nozzle no matter how broadly such nozzle is defined in the
claim, nor by what name it is identified, if such nozzle is
disclosed as an ejecting, egress or terminal means, which, if
claimed, per se, would be classified in Class 239. With
respect to the other fluid handling classes, reference should
be made to the other miscellaneous notes in "Lines with Other
Classes," notably Flexible Flow Line Storage or Retrieval and
Fog or Smoke, Colloids, Generators, Aerosols, for hose
storage and lather makers (dissolvers), respectively.
138, Pipes and Tubular Conduits, 37 for flow regulators or

141, Fluent Material Handling, With Receiver or Receiver
Coacting Means, 2 and 18+ for spray apparatus as provided
for in this (239) class claimed in combination with a source
of supply and filling means for such (239) apparatus.
169, Fire Extinguishers, appropriate subclasses for apparatus
specialized for extinguishing fires, as, for example,
diffusers and heat exchange means associated with discharge
means for handling liquefied CO[subscrpt]2[end subscrpt],
(snow nozzles) necessitated by the result to be obtained, or
means responsive to fire or heat conditions, e.g., thermal or
fusible links.
175, Boring or Penetrating the Earth, subclass 424, and the
search there noted for a nozzle adapted for boring or forming
a hole in the earth by fluid flow or jetting. Classification
is in Class 175 if the sole specific disclosure or a claim is
directed to a nozzle for boring into the earth.
222, Dispensing, for dispensers, even though disclosed for
fluid sprinkling, spraying, or diffusing where means for such
purposes are not claimed, or are claimed by name only even
though positively included if means affirmatively moving
fluid to discharge is included. Thus a mere named outlet
claimed with a gravity discharge hand carried supply
container or the like will be found in Class 239, 375
whereas the same outlet claimed with a supply and discharge
assistant will be found in Class 222 on the basis of the
relationship in the subcombination. Further, a dispenser for
particulate material having a specifically recited nozzle
which is of the nonscattering type is classified in Class
222. Also fluent material shakers of the salt and pepper type
or sifter or pattern opening type are in Class 222, whereas
hand manipulated fluid sprinklers are in this (239) class. As
hereinbefore referred to, (Glossary "Egress Means") systems
otherwise here classified having as aspirating nozzle, though
nominally included are in this (239) class.
241, Solid Material Comminution or Disintegration,
appropriate subclasses, for processes and apparatus for
comminution, per se, or in which comminution is combined with
nonspecialized types of material handling subsequent to the
comminuting operation. Class 239, Fluid Sprinkling, Spraying,
and Diffusing is considered superior to Class 241, and a
member which receives and scatters the comminuted particles
(e.g., baffle, deflector, rotary strewer, nozzle, etc.) as
provided for therein is classified in Class 239. Comminuting
devices, per se, are classified in Class 241, even though
part of the comminuting structure is disclosed to also
discharge the treated particles. A container for nonfluid
material and scattering means (i.e., subject matter for Class
239, 650 ) where the scattering means is only broadly recited
as comprising hammers, flails, pins, teeth or spikes, even
though disclosed for comminuting, is classified in Class 239
specific comminuting, cutting or crushing structure (e.g.,
knife surfaces, fixed surfaces cooperating with the cutter
edges, etc.) must be claimed to indicate classification in
Class 241. For further examples of classes considered
superior, and for examples of classes considered inferior
thereto, see Class 241, class definition, section 9.
242, Winding, Tensioning, or Guiding, subclass 905 for a
dispenser with deodorant-containing mandrel, and subclasses
370+ for a reeling device for elongated material which may
include a hose without claiming elements of the fluid supply
means or characteristics of the hose attached nozzle.
244, Aeronautics, subclass 114 for methods of dissipating
fog and the like adjacent an airport claiming a significant
relation to the airport or aircraft, and subclass 136 for
arrangements of aircraft structure to provide for the
discharging or diffusing of material in the air.
248, Supports, 75 for hose or nozzle type supports either
for use or nonuse not including elements of the fluid supply,
control thereof, nor nozzle detail means and see Lines With
Other Classes, Flexible Flow Line Storage Or Retrieval,
above.
251, Valves and Valve Actuation, appropriate subclasses for
flow line carried valves and their actuators. Class 251,
provides for valves adapted for use with a nozzle or in
combination with a nominal nozzle having no recited nozzle
features on the theory that a broadly recited nozzle
constitutes no more than a fluid conductor. A terminal spray
element which houses or includes a valving means is construed
as subject matter for Class 239.
261, Gas and Liquid Contact Apparatus, appropriate subclasses
for effecting intimate contact of a gas and liquid. The
relationship of Class 239 to Class 261 generally is
combination to subcombination. Where an otherwise appropriate
discharging means for Class 239 is claimed, such means
claimed in combination with an upstream gas and liquid
contacting means does not change the classification thereof
to Class 261. Where, however, the gas and liquid contacting
means is downstream of a discharging means, e.g., submerged
nozzle, in the absence of an additionally claimed discharging
means there beyond, classification is with Class 261.
340, Communications: Electrical, appropriate subclasses for
electric signaling, per se, or with only so much of the art
device as is essential to the operation or support of the
signal means.
362, Illumination. See subclass 96.
366, Agitating. See "Lines With Other Classes, Mortar Mixing
and Projecting-Pargeting", and subclass 102, 142, 143, 144,
336, 654, and 683.
399, Electrophotography, 239 for applying liquid developer
material to a latent image, particularly subclasses 246+ for
spraying liquid developer material.
405, Hydraulic and Earth Engineering, 36 for installed
irrigation devices or systems functioning to conduct the flow
of water in channels. Class 405 takes installed irrigation
devices and systems having below-ground terminal outlets, as
well as above-ground flumes having discharge openings for
irrigation purposes.
415, Rotary Kinetic Fluid Motors or Pumps, appropriate
subclasses for a fluid distributor combined with fluid motor
or pump structure of the type there classifiable and see the
Search Note to Class 239 of the Class Definition for a
detailed statement of the line.
417, Pumps, 151 for jet pumps whereby the motive fluid acts
by its energy of motion and by friction to entrain and carry
with it a gaseous fluid to effect the pumping action. Jet
nozzles, per se, is subject matter for Class 239; also Class
239 provides for aspirating nozzles and other mixing
arrangements similar in structure to jet pumps.
422, Chemical Apparatus and Process Disinfecting,
Deodorizing, Preserving, or Sterilizing, 255 for dissolving
apparatus, and see "Lines With Other Classes, Lather Makers"
above for statement of the line.
427, Coating Processes, 421 for processes of coating by
spraying.
431, Combustion, 2 for a method of combustion; subclasses
298+ for a wick burner and appropriate subclasses for a fuel
discharge device combined with a feature which (1)
specializes the device for use in or with a furnace or
combustion zone, e.g., a pilot burner, an incandescent, or an
arrangement which uses a portion of the furnace or combustion
chamber as a passage to provide combustion fluid, or (2)
depends on the heat generated by the flame from the system
fluid to perform its function, see (1) Note under subclass
128.
454, Ventilation, appropriate subclasses for air inlets,
outlets, registers, louvers, and the like for ventilation.
516, Colloid Systems and Wetting Agents; Subcombinations
Thereof; Processes of Making, Stabilizing, Breaking, or
Inhibiting, 1 for continuous gas or vapor phase colloid
system (e.g., smoke, fog, aerosol, cloud, mist) or agents for
such systems or making or stabilizing such systems or agents,
when generically claimed or when there is no hierarchically
superior provision in the USPC for the specifically claimed
art; and when not disclosed as adapted to ( 1 ) wet a surface
or ( 2 ) to precipitate atmospheric moisture, for which see
Class 239, the appropriate subclass for compositions for or
methods of breaking or inhibiting continuous gas or vapor
phase colloid systems.
604, Surgery, 23 for application of gases to the human body
for therapeutic purposes and subclasses 39+ for spraying
devices for treating some part of the human body having means
for contact with the body or having nozzles for entering a
body cavity or orifice.
901, Robots, subcollection 43 for a collection of spray
painting or coating robots.
GLOSSARY:
DEFLECTOR
A solid means arranged exteriorly of the egress port or last
point of confinement for dispersing or redirecting the
effluent. Some deflectors may be abrupt continuations of the
terminal flow conducting means unitarily formed therewith.
DISCHARGE MODIFIER
Any means which changes the characteristic of the fluid
leaving the terminus as by whirling, deflecting, removing, or
quieting turbulence, etc.
DISTRIBUTOR
A generic term to cover all means for effecting flow
modification (e.g., dispersion, broadcast, projection, or
scattering, etc.) of fluid, slurries or fluent material,
coming within the class definition. Means altering or
adjusting the quantity of fluid being delivered through the
discharge port or the character of the flow as, for example,
the dispersion pattern, the droplet size, the amount of
turbulence or any other control for smoothing out or
disturbing the discharge. This term is used as being generic
to discharge modification and to flow regulation.
FLOW REGULATOR
Means for altering or adjusting the quantity of effluent.
FLUID
Includes any material which is handled like a fluid (i.e.,
may be caused to flow) and meets the definition of those
materials accepted by this class in the class definition.
INJECTION NOZZLE
A terminal outlet member disclosed as connected to and as
discharging into a relatively large pressure chamber (e.g.,
an internal combustion engine or combustion turbine
combustion space).
SUPPLY HOLDER
A receptacle, container, or the like for retaining material
to be sprayed with or without additional mixing with or
entrainment in a fluid; a vessel or retainer other than a
flowing stream or flow line.
THROUGH-FLOW OR SERIES CONNECTED TYPE
A species of terminal member but of special merit and
therefore placed above in the order of superiority comprising
a plurality of terminal outlet members connected end-to-end
so that fluid may flow through them successively or a
coupling member having a side outlet means supporting and
communicating with an adjacent terminal outlet means in
addition to a downstream fluid connection. At this level the
terminal member itself will comprise lesser fluid elements.
The series connected is regarded at a level above mere
individual outlets, nozzles, or unitary plural outlet means.
WHIRLER
A means upstream of the egress means for inducing or causing
turbulent flow of a swirling or turning nature.

fluid which has left the system (or lack thereof) either in
or on the surface of the ground or in the area being
treated.
(1) Note. The responsive means react to the fluid leaving
the system through the normal distributor openings. If part
of the fluid is bled off from the normal path to the openings
and is permitted to discharge into a pan or receptacle or
against moisture sensitive means such patents will not be
found in subclasses 63+ but will be found in subclasses 67
and 68.
(2) Note. For this and the indented subclasses, a system
must at least be disclosed as a sprinkler apparatus with
control means being responsive to a condition brought about
by use of the said sprinkler. If there is no clear disclosure
that the moisture sensing means is positioned within and
senses the moisture in the area served by the sprinkler
system, it is assumed that the means senses and responds only
to atmospheric rainfall. An apparatus with a means sensing
atmospheric rainfall for control of a sprinkler or a spray
outlet is classifiable in other appropriate subclasses in
Class 239 if the sprinkler or spray outlet is positively
claimed and in Class 137 if a mere fluid system is claimed.

mechanism responding to the discharged fluid, or lack
thereof.
(1) Note. The additional control means may be either
manually or automatically operated. In those systems
including a timer or clock mechanism, such mechanism is the
overriding second control means since it will not permit the
flow of fluid to the sprayers until the selected time is
reached, or regardless of the demand placed upon the system,
or it will positively shut off the fluid when the set time
period has elapsed, also regardless of the fact that
additional demand is required externally of the system.

(1) Note. For classification herein there must be claimed as
control means something more than the mere limits defined by
traversing guide, track or tethering means or the paying out
or ultimate drag of a hose connected to supply means, i.e.,
there must be something in addition to the necessary spraying
organization which is selectively-variably imposed on the

from the supply through a restriction or check valve and
discharge occurs when the inlet line is vented to remove its
biasing effect.
(2) Note. Other means, e.g., springs or pressure operated
means, are normally provided to open the valve when the inlet
fluid conduit is vented. During the time that the nozzle
inlet is under pressure, fluid is usually bled to an
accumulator and this stored fluid is available for discharge

Subclass:
650
This subclass is indented under the class definition.
Apparatus comprising means for holding a supply of material,
other than a fluid or a slurry, and means for strewing such
material in the form of relatively small solid pieces over an
extended area on a surface.
(1) Note. The phrase "extended area" means an area larger
than that which would be covered if the material were merely
dropped from the supply holder. An area caused by the motion
of a supply holder traveling over the surface to be strewed
and merely dropping material from the supply holder is not
considered an extended area for purposes of this
classification. See Class 414, Material or Article Handling,
subclasses 467+ or Class 222, Dispensing, subclasses 608+ for
such devices. This distinction becomes very tenuous in some
cases since, for example, a conveyor operating at high speed
and unloading a wagon will cause a strewing action over an
extended area. The line between the definition of this
subclass and the art in Classes 414 and 222 as to containers
with unloading means is that where a discharge assistant or
unloading device of a type found in such classes is claimed
and the disclosure is not limited to, or a claim not directed
to a strewing action, such as may be brought about by
conveyor high speed operation, classification is in Class 414
or Class 222, but where the disclosure is clearly limited or
a claim is directed to a substantial strewing action in such
device additional to that caused merely by motion of the
supply holder over the surface to be strewed classification
under the definition of this subclass results from the
claiming of some means for strewing comprising a moving
device which is recognizable as additional to a dispenser
with a discharge assistant or a vehicle with an unloading
means. In some instances the strewing over an extended area
is caused by a deflecting means or diverging nozzle
arrangement or the like which causes material issuing from an
opening in the supply holder to spread out over an area wiser
than that of the opening. The extended area in some cases may
be little more than a line in the absence of motion of the
supply holder over the surface to be strewed.
(2) Note. In accordance with the line between the subject
matter of subclass 650 and Class 222, as indicated in (1)
Note, subclass 650 takes apparatus in which the particulate
material is strewn in the ambient so that it falls in an area
which is substantially more extensive than that covered by
merely dropping the material from an opening of a stationary
or ambulant dispenser. Where, however an opening is, or
openings are, formed in a wall of the supply holder and
strewing is effected by movement of the supply holder
classification is in Class 222. See Class 222, subclasses
160+ and 565, for examples of such strewing. Further, for
classification under the definition of subclass 650 rather
than in Class 222 the means for strewing must be positively
claimed. When such means comprises a relatively moving
element, such as a rotating distributor the reference to it
in a claim may be in the broadest terms. When, however, the
strewing means comprises a terminal outlet, such as a nozzle,
a mere broad description of such nozzle will not serve to
cause classification under the definition of subclass 650;
the recitation of the nozzle in a claim must be specific and
its strewing function must be clearly indicated by the
disclosure as being due to the specifically recited structure
of the nozzle, rather than due to ambient wind conditions or
the nature of the material dispensed, such as fine powder.
The subject matter of subclass 652 forms an exception to this
line, however; that subclass constitutes an art collection of
devices for strewing by direct hand manipulation. In close
cases it is very difficult to determine just what constitutes
the opening of the dispenser and also what constitutes an
added feature of the dispenser for spreading material, so
that placement of a patent as an original will depend on the
judgement of the classifier and the placement of like art.
Usually a discharge assistant which is in a container or
extends from the container partially thru an opening is not
considered to cause classification under the definition of
subclass 650 unless the special circumstances mentioned in
(1) Note are present.
(3) Note. Included in this definition of "strewing means" is
a pipe having longitudinally spaced apertures or
perforations.
(4) Note. Excluded under this definition is a flowable
slurry of solids in liquid; this is considered a fluid and is
classified in another section of the class. Included under
this definition is material comprising solids with a small
amount of liquid mixed therewith, but not sufficient to
permit flow.
(5) Note. A disclosure of a device for strewing or
scattering or particulate matter should not be found as an
original in any subclass following this group unless combined
with means for sprinkling, spraying or diffusing a fluid
(e.g., subclass 336) or as a nozzle, per se, disclosed for
discharging fluent solid, but also capable of use with a
fluid.

This subclass is indented under subclass 654. Apparatus
comprising an elongated strewing means extending in the
direction of its length outwardly from the supply holder when
looked at in plain view the longitudinal axis of the
elongated strewing means being substantially transverse to
the direction of any intended movement of the supply holder.
(1) Note. For meaning of "elongated strewing means" under
this definition see (1) Note in subclass 664.
Subclass:
656
This subclass is indented under subclass 650. Apparatus in
which a single strewing means is supplied with material from
a plurality of supply holders.
(1) Note. The supply holders must be primary containers of
the material such that different materials may be supplied. A
mere dividing wall in the lower portion of a container is not
included, such apparatus being classified on other features.
(2) Note. Included under this definition is any arrangement
of two primary holders, connected in such manner that a
mixture of the two materials can be supplied to the single
strewing means.
Subclass:
657
This subclass is indented under subclass 650. Apparatus in
which the supply holder is mounted on a support means so as
to be movable from a first position in which the material in
the holder is not readily movable out of the holder by
gravity to a second position in which gravity causes or
greatly assists in the movement of the material out of the
holder.
(1) Note. The support means must comprise more than a wheel
axle about which the supply holder may be tilted by the user
of the device. Such devices are classified on other
features.
(2) Note. This subclass is the locus for patents comprising
tilting containers of the dump truck type, even if details of

e.g., mounted about a wheel axle so as to be tilted by the
user of the device. The line between the two Classes, 222 and
239, Fluid Sprinkling, Spraying, and Diffusing is as follows:
a dispensing hopper, per se, but not of the tilting type goes
into Class 222, into a subclass other than 166; a dumping
vehicle combined with a hopper attachment which acts as a
spreader but not to spread a swath wider than the vehicle
goes into Class 222, subclass 166 if claimed as a dumping
vehicle and to another subclass as an original if not so
claimed; a dumping vehicle disclosure and a claim to the
combination of the vehicle and a hopper or spreader
attachment which covers a swath wider than the vehicle will
be classified in this subclass (Class 239, subclass 657).
414, Material or Article Handling, 469 for a self-loading or
unloading vehicle having a load receiving (i.e., supporting)
portion which is pivotable relative to the horizontal.

which the means for strewing comprises a flexible element
which is rotatable about an axis and is so constructed or
arranged that it assumes a substantially vertical or drooping
position when at rest and a position substantially at right
angles to the axis when rotated to strew the material.
(1) Note. For the means of "rotates about an axis" see (1)
Note in subclass 681.
(2) Note. Included as a flexible element under this
definition is an element pivotally connected to a rotary
carrier.
(3) Note. The means may be positioned within the container

172, Earth Working, subclass 45 for an implement of the
flail type for working or disturbing the earth.
Subclass:
659
This subclass is indented under subclass 650. Apparatus in
which the strewing means has an oscillating, reciprocating,
shaking or other back and forth movement while in operation
in order to effect or assist the strewing function.
(1) Note. The movement of the strewing means may be caused
either by a positive drive or by the impingement of the
material onto such means so as to cause the back and forth
movement due to the construction or arrangement of the means,
e.g., the means is of springy material which vibrates when
hit by the material.
(2) Note. The main structural difference between this
subclass (659) and the vibratory subclasses of Class 222,
Dispensing, subclasses 161, 196-203 is that in subclass 659
the vibrating member is sufficiently near the terminal
material contact point that the vibratory movement causes the
discharging material to scatter, while in Class 222 the
vibration merely causes the material to move toward or out of
the discharge outlet.
SEE OR SEARCH THIS CLASS, SUBCLASS:

Subclass:
660
This subclass is indented under subclass 650. Apparatus in
which a part of the apparatus shifts its position relative to
an adjacent part without the intervention of a human
operator, and in response to a transient condition in which a
part of the apparatus would be subjected to undesirable
stress (e.g., when a lump, clod or rock is encountered in
otherwise easily disintegratable material) if shifting did
not occur.
(1) Note. Shifting of position which occurs in order to take
up the shock of starting is not included under this
definition. Such devices are classified on other features.
Subclass:
661
This subclass is indented under subclass 650. Apparatus
comprising a means disclosed for attaching the apparatus to a
motor vehicle of the type which does not have any substantial
provision for supporting material for transportation but is
especially intended to pull a trailing vehicle or to pull or
support an implement, such as a plow, which operates to
perform its intended function while being so pulled or
supported.
(1) Note. The motor vehicle of this definition is usually
called a tractor.
(2) Note. Apparatus under the definition is typically
constructed to be used as a detachable unitary attachment for
a tractor.
Subclass:
662
This subclass is indented under subclass 650. Apparatus in
which there is a means (e.g., a leak proof supply holder)
which is especially provided because the material contains
liquid which tends to or does separate from the solid
portions of the material.
(1) Note. The material as a whole under this definition is
not a slurry, i.e., a mixture of solid particles and a liquid
which is handled as a viscous liquid. Apparatus for handling
a slurry is classifiable as if the slurry were a liquid.
Typically, the material being handled by the apparatus of
this subclass is manure, some portion of which is liquid.
Subclass:
663
This subclass is indented under subclass 650. Apparatus not
provided for in preceding subclasses and which (1) is in
combination with features other than for material handling or
treating or (2) by relative rearrangement of its parts or by
the addition or omission of a part is so changed as to become
(A) basic subject matter of the same class of a different
character or having a different mode of operation or (B)
basic subject matter of another class.
(1) Note. A mere preamble in a claim to the effect that a
device is convertible or is a conversion attachment is
generally not sufficient for classification under this
definition. The conversion feature should be spelled out as
by (a) specifically claiming one embodiment of an apparatus
having a first function and claiming with that embodiment a
feature useable only for a different function, or (b)
repeated functional statements in the claim, or (c) a
preamble which is so long and detailed that it may be
considered part of the body of the claim. Where no other
suitable classification exists a broad mention of conversion
may be enough for classification under this definition.
(2) Note. The change in the apparatus must be more than
merely placing a part in one of a series of adjacent holes,
or making a change which amounts to only an adjustment,
changing between operative and inoperative positions or other
minor alteration in the overall functioning of the device.
(3) Note. Examples of devices included under this definition
of "combined" are combinations with (1) a separator to
classify or assort different portions of the material, (2) a
plurality of different types of discharge members (e.g., a
material discharge guide for Class 222, Dispensing and a
strewing means for this class, etc.) with means, as a valve
to selectively and alternatively choose the type of discharge
depending on the material handled, (3) brake means acting on
vehicle wheels, (4) vehicle features in addition to those
required for the handling of the material, etc. Included
under this definition of convertible is an unloading or
dispensing vehicle of the type classified in Class 414,
Material or Article Handling, Class 298, Land Vehicles:
Dumping, or Class 222, Dispensing and a strewing or
scattering means of the type classified in this group of
subclasses and attachable or removable at will. Excluded from
"combined" under this definition is the combination with any

This subclass is indented under subclass 650. Apparatus
which is intended to be used by traversing a surface,
comprising an elongated strewing means extending in the
direction of its length outwardly from the supply holder when
looked at in plain view, the longitudinal axis of the
elongated strewing means being substantially transverse to
the direction of intended movement of the supply holder.
(1) Note. The "elongated strewing means" under this
definition comprises any arrangement of strewing means which
(1) results in a pattern of strewn material which is
generally elongated when the whole apparatus is not
traversing the surface, the pattern extending in the
direction of its length outwardly from the supply container
and laterally of the direction of traverse of the apparatus
over the surface and (2) is physically located outwardly from
the container in a direction laterally of the direction of
traverse of the apparatus over the surface.

strewing means" is a single rotating scatter located
outwardly of one side of the container, or two rotating
scatterers, one on each side of the container and extending
outwardly therefrom in a direction laterally to the direction
of traverse; such devices will be found in 681+. However, a

(2) Note. A means for changing a characteristic comprising
no more than a means for changing the speed of the strewing
means, a means for changing the amount of material fed to the
strewing means or a means for changing the speed or direction
of a vehicle on which the strewing means is mounted is not

(1) Note. For the meaning of "rotates about an axis" see (1)
Note in subclass 681.
(2) Note. An agitating or disintegrating means may be used
to assist the flow of material by breaking up lumps, but the
supply holder must be so constructed that the use of a
conveyor or ejector to move material horizontally is not
necessary.

(1) Note. A rotating means, e.g., a "beater", acting on the
top of the material is not included in this definition. See
subclass 680 for a beater acting on the top portion of the

comprising means acting on the material in the supply holder
for delivering it in a horizontal direction toward the
strew-means, said delivering means comprising (1) a driven
conveyor or (2) a means acting as an end of the material in
the supply holder.
(1) Note. If a series of strewing means is claimed, (e.g., a
rotating "beater" throwing material to a rotating
"widespread") a strewing means upstream of the final means is
considered to be a kind of conveyor. If, however, such a
series of strewing means is shown, but the final one is not
claimed then an upstream strewing means, e.g., a beater,
which, as claimed, functions like a final strewing means, is
considered to be a final strewing means for purposes of
placement under the definition of subclass 650.

in the ambient, rather than to another downstream strewing
means, the material being presented to each of the strewing
means in a direction which is substantially parallel to the
axis of rotation and being scattered in substantially a
radial direction.
(1) Note. For the meaning of "rotates about an axis" see (1)
Note in subclass 681.
(2) Note. Just what constitutes a plurality of strewing
units rather than a single unit with a plurality of parts is
sometimes difficult to decide. If one unit rotates on a
different axis than another, or in a direction opposite to
that of another, a plurality of units is considered to exist.
However, sometimes where there are distinct sub-assemblies,
each comprising a complete unit, a plurality of units are
considered to exist even if they rotate about the same axis.

comprising a driven strewing means and means for varying the
rate of movement of the strewing means, or of the means
delivering material towards the strewing means, independently
of the speed of the primary driving means for the strewing or
delivering means.
(1) Note. The speed varying means must be capable of
changing speed at the will of the operator while the
apparatus is in motion; merely replacing one gear with
another while the apparatus is at rest is not included. A
means which stops the motion of the conveyor or other feeding
means at a predetermined position is excluded and will be

(1) Note in subclass 681.
Subclass:
681
This subclass is indented under subclass 650. Apparatus
comprising a means which rotates about an axis in order to

(1) Note. Rotation about an axis is a movement of more than
360 degrees about the axis. The axis may be fixed or moving
but the rotating means must be essentially wheellike in
nature or moving in a substantially circular orbit about the
axis. An endless conveyor type device which moves in an
elongated orbit is not included. Such strewing means is
classified on other features.
(2) Note. An apparatus including a rotating means which acts
to strew material but which is disclosed as feeding the
