Class 015
BRUSHING, SCRUBBING, AND GENERAL CLEANING
Class Definition:
This class is intended for the assembly of patents for
apparatus (but not the process of use thereof, see (1) note)
designed or adapted for cleaning - that is to say, for the
removal of foreign matter - by any of the following means -
viz., a draft or current of air, steam, or equivalent gaseous
fluid, dry brushing along; brushing, and an applied liquid -
i.e., scrubbing, beating, scraping, erasing, shaking, wiping,
shotting, the use of squeegee, the application of an
electrostatic field or any combination including one or more
of these agencies - unless the inventions are so related or
confined to or identified with some particular industrial art
as to warrant classification therein, see the notes appended
hereto.
Washing means, per se, i.e., not combined with one of the
above noted means, are excluded, being provided for in other
classes as set forth in the notes hereto. So also all jets,
nozzles, or other means of liquid or coating material supply,
per se, where these agencies are present, are generally
treated as merely ancillary or subordinate to the mechanical
cleaning instrument or agency whose presence as a part of the
invention is necessary to the assignment of a patent to this
class and whose character determines the subtitle under which
it is placed.
Coating: many inventions in whose use cleaning or removal of
foreign or extraneous material is or may be absent or merely
incidental to a coating or polishing operation by brushing,
rubbing, or wiping, combined or not with means for supplying
a coating, cleaning, or polishing substance, are however,
included in this class, because their structure and possible
use are the same, whether intended for cleaning, polishing,
or coating. This class provides for coating apparatus having
a solid member for transferring coating material from a
source of supply to the work where the coating device is (1)
an implement as defined in the GLOSSARY below, or (2) a work
traversing device the motion of which is determined by the
intelligence of the operator rather than by the law of the
machine itself. See the class definition of Class 118 for the
line between Class 15 and Class 118.
Inventions of the types above noted as properly belonging in
this class are placed therein under four main heads - viz.,
Machines, Implements, Attachments and Accessories. See the
GLOSSARY for definitions of these terms.
See Subclass References To This Class, below, for inventions
relating to the commonly so-called vacuum cleaning art; those
using brushes for cleaning receptacles; and for most brush
and broom structures, per se.
(1) Note. Processes: Where both process and apparatus for
its practice are claimed, the patent is classified as an
original in the class appropriate to the process claimed and
cross-referenced to this class (15) for the apparatus. (See
References To Other Classes, below, for drying processes,
processes for cleaning and liquid contact with solids, for
processes for hulling and comminuting seeds with or without
fluids, and for coating processes.)
(2) Note. Processes and apparatus which remove an integral
portion of the object or material dealt with rather than of
extraneous or foreign matter only are found in the
appropriate manufacturing class. For related art, see
References to Other Classes, below.

246 257, and 300 to 422, for inventions relating to the
commonly so-called vacuum cleaning art.

GLOSSARY:
ACCESSORIES
Devices not classifiable elsewhere and which perform no
cleaning function but which are merely ancillary to machines,
implements and attachments classified in this class.
ATTACHMENTS
As an exception to the other GLOSSARY definitions, patents
which recite that (1) a cleaning or coating means is attached
to an object which is cleaned or coated thereby or (2) that
any device is attached to a cleaning or coating agency, have
been classified as attachments regardless of whether they are
machines or not, disregarding the relative superiority of
these subclasses in the classification schedule.
IMPLEMENT
Defined in this class as a work contacting cleaning or
coating agency subcombination which as disclosed, could be
either (1) manipulated manually as a tool, (2) moved by a
machine, as defined above and constituting a part thereof, or
(3) held in place by support means for direct manual
application of the work thereto. (Note: A hand held nozzle is
not an implement as defined above and is classified elsewhere
as a machine subcombination).
MACHINE
Defined in this class as an organization including a
mechanism, which contains within itself its own guide for
operation, to move either (1) a cleaning agency, or a coating
agency of a type recognized in this class, relative to the
work surface or (2) a means to constrain the work and said
agency to some type of definite relative motion in response
to manual or other actuation. (Note: A guide on a stripping
brush aids in directing the brush but does not constrain it
to any definite path other than that determined by the work
itself).

Subclass:
3.5
This subclass is indented under subclass 3. Machines for
cleaning the inside of tubular conduits, such machines
comprising means for introducing a carrier fluid into a
conduit either in addition to or in the absence of normal
fluid flow in the conduit, combined with means to introduce a
solid cleaning member, agent or material into the stream of
fluid or the conduit whereby the cleaning member, agent or
material is conveyed or pushed through the conduit by fluid
pressure for mechanically cleaning the inside of the
conduit.
(1) Note. Devices in which the cleaning instrumentality is
propelled through the conduit by mechanical traction
developed by a motor means which is actuated by a fluid not
confined solely by the conduit are excluded and may be found
in the appropriate implement subclass of this class. See for
example, subclass 104.12.
(2) Note. In the patents in this group of subclasses the
cleaning means, in the carrier fluid, is introduced at one
end of the conduit and at least the fluid has an egress point
at another place. Thus, the cleaning of receptacles, in which
the cleaning means is introduced and removed from the mouth
of the receptacle, is excluded, an example of such devices,
being the bottle shotting inventions classified in subclass

may be a structure of hard material for scraping the interior
of the conduit or of soft materials as sponge or rubber, for
wiping the surface to be cleaned, or it may be a soluble or
insoluble comminuted or granular material, as sand, glass
beads, or softer material. Patents in this subclass which
utilize sand as the cleaning material to perform a disclosed
cleaning (and not abrading) function are included as a
specific exception to the general line with Class 451,
Abrading, because the structures and modes of operation of
such systems are similar to those of systems which circulate
the other stated types of materials.

above. Also see section IX of the class definition of Class
451 for another statement of this line. Special note to
cleaning of open ended tubular work: A claim directed to a
method or apparatus which by disclosure includes removal of
base material is to be found in Class 451; whereas a claim
directed to similar method or apparatus, which by disclosure
includes removing extraneous material only, is to be found in
Class 15 if the sand or other scouring means is carried
through the tubular work by a fluid stream. Note that bottle

Subclass:
424
This subclass is indented under subclass 104. Implement for
disintegrating and removing indicia from a surface by rubbing
contact therewith, which implement comprises an erasive body
composed of particles which are so in cohesive as to result
in the disintegration of the surface-contacting portion of
the body, along with the indicia, by the force of the rubbing
contact, before such force can cause substantial mutilation
of the surface.
(1) Note. A patent to an eraser comprising an abradant body
(i.e., a body including crystalline particles with sharp
edges which mutilate a work surface) will be placed in an
appropriate subclass, Class 451, Abrading. Absent disclosure
of the presence of crystalline particles in the erasive body,
the patent to the eraser will be placed in this, the generic
locus for erasers, even though the description may
characterize the implement or the process as `abrading'. A
patent claim will be deemed generic, for placement in this
class, when the claims are to erasing and not, specifically,
abrading, even though the disclosure comprehends, or is
limited to, an erasive body including crystalline particles.
See the "Search Class" notes, below, for placement of still
other types of mutilating erasing instrumentalities.
(2) Note. The term "eraser" is employed herein to refer to
the implement; that is, to the piece of erasive material and
all the structure associated therewith for performance of an
erasure; or to such a piece, per se, when that is all that is
used for such performance. The term "erasive body" is
employed to designate the subcombinational aspect of such a
piece in relation to other structure associable therewith for
the performance of the erasing function.

including means (e.g., strand, finger cot, magnet) for
retaining the implement on another object (usually adjacent
the writing surface) during the time in which the performance
of an erasure is not required.
(1) Note. The nonuse retaining means may associate the
eraser with the other object during use as well, and a
disclosure of both use and nonuse retention will not bar
placement of a patent in this subclass.
Subclass:
427
This subclass is indented under subclass 425. Implement in
which the handling means is adapted to partially enclose a
piece of solid coating material with an end thereof exposed,
whereby the handling means constitutes manual manipulating
means for the coating operation as well.
(1) Note. A patent to the combination of an eraser of this
class with a mechanical pencil or with the sheath of an
ordinary pencil will be placed in this subclass, or in a
subclass indented hereunder, only when no more of the pencil
structure is claimed than is necessary to define the
relationship of the eraser therewith. Class 401, Coating
Implements With Material Supply, subclass 52 will take the
combination claiming pencil structure in greater detail than
is necessary to define such a relationship.
Subclass:

This subclass is indented under subclass 427. Implement in
which the eraser, or a mounting therefor, is hollow to fit
about, and close to, the end of the enclosure at or adjacent
the exposed end of the piece; or is mountable in an offset
relationship to the enclosure axis adjacent said end.
(1) Note. The claiming of the piece of solid coating
material will not bar placement of a patent in this subclass,
provided that no more of the piece, nor of any other part of
the implement, is claimed than is necessary to define the
relationship of the eraser therewith (i.e., its particular
foreend mounting for this subclass), a claim of this nature
being considered to be in accordance with the statement of
the line with Class 401, Coating Implements With Material
Supply, set out in (1) Note to subclass 427.

This subclass is indented under subclass 104. Manually
manipulable implement comprising a tool of incompressible
solid material and having either a single element or a
furcated plurality of elements for contacting a work surface
and applying liquid coating material (e.g., ink) thereto in a
writing operation; or comprising a device connectable to such
a tool for supporting or retaining the tool for manual
manipulation during a writing operation.
(1) Note. The line between this subclass and Class 33,
Geometrical Instruments, with respect to plural penpoints, is
as follows: Class 15, subclasses 760+ will take a patent for
an implement having plural penpoints, wherein (1) the
construction is such that the penpoints are intended to be
used independently of each other, or (2) if designed for
simultaneous operation, the mark produced by one penpoint
complements and is contiguous to the mark (s) simultaneously
produced to the other (s) to produce unitary indicia (e.g.,
shading pen); or the marks are wide enough to be
characterized as stripes, rather than lines. When the plural
penpoints are adapted, and used, sorely for the simultaneous
drawing of a plurality of independent and spaced lines,
placement of the patent will be in Class 33.
(2) Note. For the line between this subclass and the
indented subclasses, and Class 401, Coating Implements With
Material Supply, see (4) Note under Class 401, subclass 221.
(3) Note. This, rather than an indented, subclass is the
locus for patents to inventions in penholders, per se, which
include no claimed detail of the structure for retaining a
penpoint. Included in this subclass are patents to penholders
having: (a) relatively movable e.g., yieldable, angularly
adjustable) handle portions; (b) ink guards; see, however,
subclass 443 for an ink guard contacted by the finger during
writing to constitute a finger rest, as well; (c) dip gauge
attachments. Patents to penholders provided with plural
penpoints, but which claim no penpoint-holding detail, are
also collected in this subclass. A cross-reference has been
placed in this subclass of each patent including novelty in
any of the above features but classifiable in a subclass
indented hereinbelow because of further novelty in structure
conforming to the definition of the indented subclass. It is
expected that this procedure will be followed for such
patents which issue in the future.

claimed. Merely reciting the tool as being "metal" or
"metallic" is not adequate for placement in this subclass,
but the naming of a particular metal or alloy will suffice.

(1) Note. Ink retained in the space between confronting
surfaces of a broad face tool (e.g., ruling pen) is
considered to be material supply, and an implement having
such a tool is considered to be an implement with material
supply for Class 401. A patent for such an implement will be
