Class 118
COATING APPARATUS
Class Definition:
This is the generic class for apparatus for applying or
obtaining a surface coating on a base and/or apparatus for
impregnating base materials and takes all such apparatus not
provided for in other classes.
The coating obtained may be permanent or transitory. The
coating may be supplied solely by extraneous materials, as in
a painting or waxing operation, or may be supplied wholly or
in part by the base materials as in the formation of an oxide
coating on a metal base. The coating may consist of an
emulsion, dispersion, solution, admixture or oil which is
clearly disclosed as leaving a residual film, layer or
continuous deposit on the base. However, mere application of
water to a base is excluded and classified elsewhere in
generic liquid contact class or other appropriate related
liquid contact classes even where the stated function is to
lubricate, coat or protect the base. See Lines With Other
Classes and Within This Class, below, for additional
discussion concerning exclusions.
The class also provides for apparatus for preparing the base
for the coating operation, subsequent treatment of the coated
base and ancillary noncoating apparatus, per se, when there
is no class which specifically provides therefor. The
treatment of the surface coating may be by application of
water or other solvent alone, e.g., where a sponge supported
on a fixed base is disclosed as applying water to a stamp to
moisten the coating thereon. On the other hand, application
of water or a solvent to a coated surface to remove the
coating or to clean it without otherwise modifying it, would
be excluded from Class 118 and classified in the appropriate
surface treating class.
To be classified in this class the work treated must not be a
part of the coating machine itself but must be an article
separate and distinct therefrom. Machines having as a part
thereof means to condition or prepare the machine are
generally classified with the art that provides for the
particular machine, but see MOLD OR DIE COATING, for an
exception to the line.
For other coating apparatus, per se, see Lines With Other
Classes, below.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
EXCLUSIONS
Mere application of water to a base is excluded and
classified in generic liquid contact Class 134 or other
appropriate related liquid contact classes even where the
stated function is to lubricate, coat or protect the base.
However, see the class definition of Class 134, (2) Note,
"Coating and Impregnating", paragraph (b).
COATING COMBINED WITH OTHER OPERATIONS
Many classes provide for coating or impregnating combined
with apparatus for other operations. In general, the
assignment of patents has been on the basis of the noncoating
operation where apparatus for performing such operation is
claimed. However, this class does provide for certain
combinations, as set forth in the various subclass titles
above and including subclass 75 in the class schedule. By way
of example, this class provides for the combination of
coating apparatus and cutting or punching apparatus (subclass
35); this class also provides for coating apparatus combined
with means to prepare the work to receive the coating
(subclass 72). For combinations of coating and noncoating
devices excluded from this class, see References to Other
Classes below referencing Coating Combined with Other
Operations.
B. COATING APPARATUS, PER SE, FOUND ELSEWHERE
Certain classes provide for coating apparatus, per se.
Classification of patents is in these classes when coating
subclasses occur in such art class and are defined to receive
such patents. These locations are detailed in References to
Other Classes, below.
C. TREATMENT OF TEXTILES OR LEATHER
Class 118 provides the generic place for coating textile or
leather work, including the working of the textile or
leather, except (1) where a chemical reaction takes place
between the coating and the work, or (2) where the means to
work the textile or leather before, during or after the
coating treatment is other than to modify the coating. For
example, this class provides for textile or leather coating
apparatus having working means to insure proper coating or
impregnation (subclass 427 by way of example) or having means
to modify the coating on the work (subclasses 100+), but does
not provide for combination of coating devices and means to
work the base for other purposes.
For coating of textiles or leather excluded from Class 118,
see References to Other Classes, below.
D. MOLD OR DIE COATING
Class 118 provides in appropriate subclasses for apparatus
for coating molds or casting dies where no more of the
molding or casting apparatus is claimed than is necessary to
present the mold or die to the coating device or station. The
coating which is applied must act to promote or perfect the
molding operation and must not be a constituent part of the
molded product such as a chocolate shell for a filled
chocolate candy. Excluded from this class also are mold
coating arrangements where application of the coating is
dependent at least in part on the use of the apparatus in a
molding operation as where heat from the molten material
vaporizes a coating material for deposit on the mold
surfaces.
Also see References to Other Classes, below, referencing this
section.
E. MOLDED, SHAPED OR CONFIGURED COATINGS
This class (118) provides for apparatus for the application
of coating material to restricted areas of the work such as
in stripes, bands or spots (subclasses 211+, 301 and 406). In
subclasses 321 and 323 may be found apparatus in which a
spray gun is manipulated to apply the coating in a particular
pattern. This class also provides for devices for modifying
the coating by removing certain portions of it from the work
(subclass 102). This class also provides for apparatus for
producing configured coatings applied to base under the
control and/or direction of electrical, magnetic or radiant
energy applied to the coating material in a predetermined
pattern (subclasses 620+).
For molded, shaped or configured coating excluded from this
class, see References to Other Classes, below.
F. COATING EDIBLE MATERIALS, ANIMAL BODIES AND VEGETATION
This class provides for apparatus for applying fluent coating
material to foodstuffs. By fluent material is meant any
material which flows or may be handled like a liquid or fluid
substance. By way of example, flour, salt or sugar are
considered to be fluent materials.
This class does not provide for the application of material
handled as discrete units to the work, such as nut meats,
which are positioned individually on the work. This class
does not provide for the treatment of living animals and does
not provide for the treatment of growing plants. For subject
matter for coating edible materials, etc., excluded from this
class, see References to Other Classes, below
G. THE LINE BETWEEN CLASS 118 AND CLASS 239
The line between Class 118 and Class 239 is as follows: Class
118 provides for spray type coating devices having means to
handle or manipulate the work relative to the spray device
(subclasses 300+). Class 118 also provides for spray system
wherein the coating apparatus control means is responsive to
the presence or absence of work (subclasses 2+). Class 118
also provides for spray type coating devices which are
supported by or traverse the surface of the work and in which
the direction of motion of the spray type device is
controlled by the law of the machine, rather than by direct
manipulation of the operator.
Class 239 takes spraying or scattering systems, per se, where
no work handling structure is recited in the claims. Class
239 also takes work surface supported and traversing spray
type coating devices in which the direction of motion of the
carriage is determined at the will of the operator. The
presence of guide structure which merely aids in the
determination of the direction of motion by the operator does
not exclude the subject matter from Class 239. By way of
example, devices for spray painting a stripe on the surface
of a road having a guide for aiding the operator in
maintaining the direction of the painting device can be found
in Class 239; devices for spray painting a stripe on a
roadway having means engaging the edge of the road, which
means positively limits the direction of motion of the device
once the device is put into operation, can be found in Class
118 (subclass 305). In Class 239 the device may have a
shield, guard or deflector to confine the distributed
material; however, if the material is discharged through a
stencil or applied in a particular predetermined pattern, the
device is excluded from Class 239 and is found in Class 118
(subclass 301).
In the matter of a railway car traveling and being guided on
rails, if the discharge is directed at the rails, the device
may be found in Class 118 (subclass 307); if, however, the
discharge is directed at the ground on either side or between
the rails, the device can be found in Class 239. Lawn
Sprinklers which traverse a hose, supported on the ground are
found in Class 239 (subclass 748) since the ground on both
sides of the hose (equivalent to the rail in the example
cited above) is being sprayed.
In regard to the mixing with fluid and spraying of
particulate solids, the line between Class 118 and Class 239
is as follows: In the absence of a work surface or support
claimed in relation to the spray apparatus, (which indicates
classification in Class 118), devices which add the
particulate solids to fluid and discharge the mixture through
a claimed terminal element recognized for Class 239, or
devices which add particulate solids downstream of a recited
terminal element of the Class 239 type in an unobstructed or
unconfined space are classified in Class 239; devices which
add particulate solids to fluid discharging from an opening
or nozzle (nominal of specific) in a confining and guiding
chamber or pipe with or without flow guides therein and
discharging the mixture from the chamber or pipe through a
mere opening or unmodified outlet, are classified in Class
118.
Apparatus comprising a container for nonfluid material and a
scattering or strewing means for the material will be found
in Class 239, subclasses 650+.

GLOSSARY:
COATING
The term "coating" is used throughout the definitions in a
generic sense to mean either (1) an initially fluent film or
layer of material lying on or bonded to the surface of a
base, or (2) an impregnating material which penetrates the
base either partially or completely and all or part of which
is retained therein, either in its original form or
physically or chemically combined therewith.
DOCTOR, WIPER, OR SCRAPER
Any instrument acting on the coating or on the work for the
purpose of spreading or removing surplus coating material.
The instrument may be, for example, a solid scraper blade, a
roller squeegee or as in the case of an "air doctor" a
gaseous blast. For definitions of terms appearing in subclass
titles and not mentioned in the above definitions, see the
definitions to the particular subclass in which the term
appears.
WORK
