Class 414
MATERIAL OR ARTICLE HANDLING
Class Definition:
Apparatus, device, implement or method for placing or
displacing particular articles in a particular manner or with
reference to a particular support, for loading or unloading
vehicles with materials or objects in general, charging or
discharging furnaces, bins, chambers, or other receptacles,
stacking or piling articles or materials, also combinations
of general types of carriers or forwarding mechanisms, which
types, per se, are separately classified elsewhere, and
general types of elevators, cranes, or hoists when associated
with special means for handling the load to place it on the
carrier or remove it therefrom.
(1) Note. The miscellaneous subclass of this class is
designed to receive any material-moving mechanism for which
no place has been established elsewhere.
(2) Note. The term "handling" in the title is intended to
indicate in a general way those more or less complex and
intricate movements, imparted to matter by instruments or
mechanisms which are deemed analogous to nonshaping
manipulations, or the varying movements imparted to matter or
objects by hand.
(3) Note. Treatment of matter to change its shape or
condition is not included in this class. As fabricating and
material-conditioning apparatus have commonly associated with
them means for bringing the material to the shaping or
conditioning instrumentalities or carrying it therefrom,
combinations of handling or conveying means with fabricating,
shaping, or conditioning means are classified on the basis of
the latter.
(4) Note. Earthworking in general effects a change in the
shape or form of matter and is classified on that basis; but
the removing of earth by power scoops, shovels, and the like,
which operate in the same manner whether removing a pile of
loose coal or grain or the loose earth from an excavation,
are classified on the basis of handling in this or other
material-moving or transportation classes. Otherwise stated,
those inventions relating to the excavating art, including
power scoops, shovels or the like in which movement is
imparted to such scoops or shovels subsequent to or in
addition to those movements deemed necessary to complete an
excavating operation, which additional movement is usually
for transporting the excavated material to a disposal point,
are considered to include such handling of the excavated
material as will provide a basis for classification in this
class (414). Even the teeth of scoops, commonly placed there
for excavating hard earth, may be broadly claimed in
combination with a handling-machine otherwise falling into
this class without excluding the patent from this class,
although the specific teeth if claimed particularly, would go
to a class of excavating or earthworking.
(5) Note. The separation of mixed solid materials by an
operation depending on differences of size, form, mass, or
other physical properties of the mixed materials or objects
is deemed to be a highly special form of moving or handling
materials, and the classes of separating are deemed superior
to this class.
(6) Note. Regarding land or water vehicles supporting other
load-handling devices, the vehicle is deemed to be a
mechanism unless the handling mechanism is so combined with
and related to the vehicle as to load or unload that vehicle
or handle its load or cargo.
(7) Note. For a thorough search in material-handling, all
subclasses found in the index indicating by title a
fabrication or material-treating class, with feeding,
conveying, or other handling means, should be inspected.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Combined conveyors, carriers, and forwarders of types now
included under Class 198, Conveyors: Power-Driven, are to be
found in Class 198; but combined carriers, the separate
elements of which are in different classes, are provided for
in this class.
Vehicles in which the body is merely moved or tilted to dump
by gravity are classified in Class 298 or in Class 105,
particularly, subclasses 238.1+; however, in regard to Class
298, see also the reference thereto in subclass 469 of this
class (414).
For handling where manipulation during the progress of manual
work is involved or for handling including the engagement of
more than one part to aid in manual assembly of such parts,
see Class 269, Work Holders. The fact that the article
handled is assembled manually with an abutting receiver will
not exclude a handling mechanism from Class 414.

work which is to be heated in the structure, or (b) material
in the nature of fuel which is to be consumed during a
work-heating operation, to, adjacent to, into, out of, from,
within, etc., the structure.
(1) Note. While the basic concept of this and the indented
subclasses is that of the combination of the chamber and the
means for charging or discharging material thereto of
therefrom, rigid adherence to that concept would have
resulted in a considerable scattering of the art of the
predecessor area (subclasses 18-37 of former Class 214).
Accordingly, claims to the charging or discharging means are
originally classifiable here (with the below-mentioned
exception) if the claims make clear, or if such is the sole
disclosure, that the destination of source of the material is
a chamber of the kind under consideration. However,
exceptions are made in the instance of a charging or
discharging means which is proper for Class 198, or one which
is proper for some other area of this class (414), in which
event original classification is there and the patent is
cross-referenced to this area (147+).
(2) Note. The claiming of, for example, (a) a heating
chamber and heating means therefor, with or without a
charging or discharging means, or (b) structure of a heating
chamber which relates only to its heating function (e.g.,
lining, configuration, etc.) or (c) discharging work which is
molten in form, and is handled as a liquid (e.g., not merely
as the contents of a receptacle), from a heating chamber,
presents subject matter which is beyond the scope of this
class (414).

Apparatus comprising means for carrying, moving, placing,
transporting, etc., one or more wheeled vehicles from, in,
into, on, onto, off from, out of, within, etc., a facility
where it may be allowed to remain for a period of time. The
facility may comprise only a site for parking one vehicle, or
it may involve a plurality of parking sites; in the latter
case, in particular, it may include building structure (e.g.,
as in a parking garage). Any parking site, or any or all of
a plurality of such sites, may be either (a) fixed in nature,
or (b) of a kind which is occasionally or frequently
subjected to being moved bodily (e.g., orbitally, laterally
displaced, etc.).
(1) Note. "Site", as used hereinafter, shall be understood
to mean parking site.

Subclass:
228
Facility includes structure (e.g., ramp, angularly related
successive locations for a vehicle, etc.) necessitating
self-propellability or steerability of vehicle:
This subclass is indented under subclass 227. Apparatus
wherein the facility is so constructed as to require that a
vehicle, which is to move or be moved from one location to
another at or in the facility, have a capability for
propelling itself and/or of being steered.
(1) Note. While it is commonplace in the parking facility
art, usually as a matter of convenience or expediency, to
drive a vehicle onto or off from a site, this and the
indented subclasses are limited to providing only for those
facilities which are so constructed that some or all of the
movement of a vehicle is possible only if the vehicle
possesses one or more capabilities of the nature described.
In other words, this subclass does not extend to include a
mere forward or backward movement of a vehicle on a level
surface because movement of that nature may be accomplished
manually if necessary.
(2) Note. A patent is proper for original placement here if
there is any suggestion in the claims of structure which
necessitates self-propellability, etc., on the part of the
vehicle.
(3) Note. A patent is properly cross-referenced here when
it is clear that, in spite of the absence of structure for
this subclass, an intention exists that an operator remain
with the vehicle during at least a portion of the time while
it is being moved to or from a site.
Subclass:

wherein the facility includes a site which comprises an
upwardly inclined, pivotably mounted surface along which a
vehicle moves under it own power. The axis of pivot is
horizontal and is perpendicular to the direction of travel of
the vehicle.
(1) Note. Occasionally the purpose of making the site
pivotable is to create space therebeneath for the parking of
another vehicle.
Subclass:
230
Caused to pivot by advancing vehicle:
This subclass is indented under subclass 229. Apparatus
wherein the site pivots as a result of the movement of a

provided with a system for controlling the movement of a
vehicle to or from a site, which system has a capacity for
accepting, comprehending, and responding to delivery,
retrieval, etc., instructions which are of a variable
nature.
(1) Note. The concept of this subclass is that of a control
system which, as a minimum, is capable of accepting (by code
or otherwise) the designation of a site, analyzing the
location thereof, selecting a route thereto, causing a
vehicle moving means to follow that route and either deposit
or pick up a vehicle upon reaching the site, and then causing
the moving means to return to its usual locus for receiving
incoming vehicles or discharging outgoing ones, or to an
alternative locus if so ordered.

Subclass:
233
Including one or more movable sites:
This subclass is indented under subclass 227. Apparatus
wherein the facility includes at least one site which
comprises a movable, vehicle-supporting device or element to
which an incoming vehicle moves, or is moved, and on which
the vehicle remains during its stay, or the predominant
portion thereof, at the facility. The site and its vehicle
may move frequently relative to the facility (e.g.,., to
permit the receipt or discharge by the facility of other
vehicles), or their movement may be only that necessary for
the site to move its vehicle to the specific location which
they will occupy and to return it therefrom.
(1) Note. The following observations may be made concerning
the movable site concept: (a) the phrase "device or element"
embraces structures ranging from a driven carrier (e.g.,
conveyor, elevator, etc.) to a single supporting member
(e.g., dolly, platform, pallet, etc.) so long as it is
susceptible of moving, or being moved, while supporting a
particular vehicle which will remain thereon for most of its
stay at the facility; (b) a movable site most frequently, but
not always, is located on a translatably movable transporting
member of one kind or another. Such a transporting member may
be (1) a carrier which receives a single vehicle and which
has some degree of independence of movement, as provided for
in subclasses 236+ below, or (2) a
plural-vehicle-accommodating carrier (e.g a conveyor),
certain ones of which are provided for in subclasses 242+
below, and see the definition of that subclass for certain
arbitrary distinctions as to what constitutes a movable site
therefor.
Subclass:
234
Vehicle assigned to particular supporting member (e.g.,.,
platform, dolly, cage, etc.) having some degree of
independence either as to means, time or direction of
movement:
This subclass is indented under subclass 233. Apparatus

vehicle and forms the supporting element on which it rests
during all or a predominant portion of its stay in or at the
facility, and which member exhibits a degree of independence,
as evidenced, for instance, by (a) being carried by a
transporting device, or driven by an external means, but
being separable or detachable from either one to follow
another path or remain stationary, (b) having its own drive
means and moving independently in a prescribed path or at
random or remaining at rest, or (c) otherwise exhibiting a
degree of independence of time or direction of movement.
(1) Note. A separate supporting member of the kind
contemplated by subclass 239 below, but intended for manual
movement and therefore lacking the drive means required for
that subclass (239), is found here.
Subclass:
235
Supporting member separable from endless, member-transporting
carrier, or disengageable from endless drive means, and
movable away therefrom for receiving, discharging or storing

endless carrier, or is driven by an endless drive means, and
is separable, or disengageable, respectively, therefrom for
moving apart to a location at which it may receive or
discharge a vehicle or to a fixed site where it and the
vehicle will remain.
Subclass:
236
Plurality of supporting member moved in recirculating fashion

wherein a plurality of supporting members are moved in a
single, fixed path, or in a plurality of paths which share a
common origin and terminus, and wherein the means for moving
the member comprises a plurality of successively arranged
driving devices.
(1) Note. The successively arranged driving devices may be
powered from a single source.
Subclass:

Subclass:
239
One or more separate supporting members and means to impart
independent, linear or partly linear, movement thereto:
This subclass is indented under subclass 234. Apparatus
comprising at least one separate member for receiving and
supporting a single vehicle and means to move any or all such
members in an independent manner and in a path which is, at
least in part, linear in direction.
(1) Note. The moving means may be a self-contained drive
means, or it may be an external drive means; if there are a
plurality of supporting members, an external drive means
moves only one member at a time.
(2) Note. See (1) Note of subclass 234 above.
Subclass:
240
Member moving from particular location to discharge and/or
receive vehicle, and returning thereto:
This subclass is indented under subclass 239. Apparatus
wherein a member is associated with a specific location in
the facility and occupies that location when supporting a
parked vehicle, the member leaving that location only to
obtain a vehicle which is to be parked on it or to deliver
such a vehicle.

On driven, plural-site carrier initially receiving vehicle:
This subclass is indented under subclass 233. Apparatus
wherein a movable site comprises any vehicle accommodating
space on a driven carrier which is in excess of the space
required for the carrier to transport a single vehicle, and
wherein the carrier is the one to which the vehicle moves, or
is moved, upon arriving at the facility.
(1) Note. Vehicle accommodating platforms attached to an
endless drive member, or mounted on a rotatable wheel,
obviously constitute movable parking site. Less clear,
however, is the case of, for instance, a two-, three-,
four-car, vertically and/or horizontally driven, carrier;
while such a carrier frequently is intended to transport only
one vehicle at a time, and often does only that, the fact
that it is common practice in the parking facility industry
to utilize, when operating at or near the capacity of the
facility, all available vehicle-accommodating space therefore
necessitates treating any space in excess of that required
for one vehicle as a movable site, since a corresponding
number of vehicles may be left thereon for as long a period
as desired.
Subclass:

ordered. Further refinements of such a system might include
(a) investigating, on the part of the means, of the status of
its destination and, if found to preclude the execution of
its mission, requesting an alternative destination, (b) as in
(a) but the assumption by the means of the responsibility for
finding a suitable alternative destination, etc., or (c)
identifying a particular article among a plurality of
articles and retrieving that article.

SELF-LOADING OR UNLOADING VEHICLES:
This subclass is indented under the class definition.
Devices in which a vehicle has a load receiving and
transporting portion and handling means carried by such
vehicle adapted (a) to deposit a load into or remove a load
from said receiving portion, or (b) to transfer such load to
a position for subsequent transfer into said receiving
portion.
(1) Note. Where the handling means is of the Class 193 or
Class 198 type, the load may remain on the handling means
rather than be deposited into or removed from the load
receiving or transporting portion. This exception to the
line has been permitted because of the similarity of these
devices to those in which manual transfer of the load from
the conveyor to the vehicle body is provided for in (b) of
the subclass definition, and because no appropriate
classification is available in Classes 193 and 198.
(2) Note. The combination of a vehicle having a load
receiving and transporting portion and a load therefor, which
load is capable of moving itself to or from the vehicle, is
found in this and the indented subclasses. A combination of
this nature is placed here, rather than in one of the areas
commencing with subclass 333 and ending with subclasses 373+,
above, on the rationale that there is no means involved which
is always external of the vehicle (i.e., after loading has
been accomplished, nothing external of the vehicle remains).
(3) Note. A vehicle having a loading or unloading means
which is disclosed as relying on an external source of power
to operate it, but which source is not claimed, is classified
here (e.g.,., a vehicle having a load moving means operated
by a cable connected to an external pulling device, but
wherein only the cable is claimed); however, if the external
source of power is claimed as such, then classification is in
one of the areas beginning with subclass 333 and concluding
with subclasses 373+.
(4) Note. Occasionally, the classification of a patent to a
vehicle and a means external of the vehicle for cooperating
in the loading or unloading of the vehicle may be in this
area (467+) rather than in those subclasses beginning with
333 and concluding with 373+. Consider the instance of a
vehicle #1 for transporting a load, which vehicle has located
thereon another vehicle #2 for transporting increments of the
load of vehicle #1 while loading or unloading that vehicle -
assuming that there is a means external to vehicle #2
(although not external to vehicle #1) which cooperates in the
loading or unloading of vehicle #2, the apparatus
nevertheless does not amount to more than a self-loading or
unloading vehicle for this area (467+), which fact should not
be obscured by classifying the patent in any of the superior
subclasses previously mentioned.

(1) Note. This and the indented subclasses constitute,
principally, a reclassification of subclasses 501 and 505-511
of former Class 214 (subclasses 502-504 of that class, now
subclasses 471-473, having been left as they were, except for
being screened for conflicting subject matter). While the
art of the 501 and 505-511 area consistently included a
load-receiving portion pivotable about a horizontal axis, as
required by former subclass 501, it occasionally lacked the
"handling means" of its outdent, former subclass 500, now
subclass 467. Accordingly, in order to avoid a significant
redistribution of the subclasses 501+ art, this subclass
(469) has been defined in such a manner as to identify the
pivoting of the load-receiving portion as constituting the
handling means. In addition, certain of the subclasses
indented hereunder were established in order to provide for
specific types of devices which conventionally are construed
to be "handling means".
(2) Note. "Load-receiving portion", as used herein, denotes
the one or more elements, members, etc., of a vehicle which
supports a load during transit, as distinguished from an
element, etc., which supports a load only during the loading
or unloading of the vehicle.
(3) Note. "Generally horizontal plane" usually is
descriptive of the surface from or to which a load moves to
or from the vehicle.

ELEVATOR OR HOIST AND LOADING OR UNLOADING MEANS THEREFOR:
This subclass is indented under the class definition.
Apparatus comprising a ground-, structure-, vehicle-, or
otherwise-supported elevator or hoist for raising or lowering
a load, the load being raised, etc., on a load carrier (or,
as sometimes identified herein, a carrier) in the form of a
bucket, cage, car, grapple, hook, lifting fork, platform,
etc., which load carrier moves in a vertical or inclined
path, and a means for loading or unloading the carrier or for
facilitating the loading or unloading thereof.
(1) Note. A significant difference between an elevator and
a hoist is that the former includes structure for guiding its
load carrier.
(2) Note. This subclass and subclass 95 of former Class
214, previously included the limitation "self" (as applied to
the loading or unloading means) in its title. While a
significant portion of the art may meet such a limitation,
the art seen in the reclassification of this subclass and
those indented subclasses formerly numbered 660 (now 628+),
670-674 (now 630+), 701 (now 640+), and 730, 731 (now 662+),
as well as that seen in newly developed subclasses 659+,
indicated that the limitation could not be retained.
(3) Note. In the reclassification of the subclasses
mentioned in (2) Note, it appeared appropriate, except in the
case of subclasses 659+, to distinguish those elevators or
hoists which claimed portability (e.g.,., vehicle-mounted)
from those which did not; however, it is pointed out that,
(a) the art in the new "portability" subclasses has not been
screened against the vehicular areas of the class, and (b)
the establishment of the "portability" subclasses does not
mean that there are not patents to vehicle-mounted elevators
or hoists in other, non-reclassified subclasses which depend
from subclass 592.
(4) Note. The line between a material handling device
proper for this Class (414) and an elevator or industrial
lift truck proper for Class 187, Elevator, Industrial Lift
Truck, or Stationary Lift for Vehicle, is as follows: (a)
Class 414 provides for load engaging structure in which the
load support surface travels in a generally vertical primary
lift direction and (1) is mounted for movement in a direction
other than the primary lifting direction (e.g.,., tilting) or
(2) has an additional load handling structure (e.g.,.,
conveyor) or (3) is constructed in such a manner that the
load support surface is inherently self-charged or
self-discharged along the primary lift direction; and (b)
Class 187, Elevator, Industrial Lift Truck, or Stationary
Lift for Vehicle, provides for industrial lift trucks or
components thereof when the load is shifted in its entirety
in a primary lifting direction from one level to another
vertically spaced level and may additionally include (1) mere
pivoting or tilting of the load supporting structure for
detachment or storage or (2) retaining of a received load on
the support surface.

495 for a self-loading or unloading vehicle having a
load-receiving portion which is movable in a vertical or
inclined path. While that area (495+) does not exclude a
vehicle-mounted elevator (e.g.,., an industrial truck), the
placement of the art (in former Class 214) appears to have
evolved in such a manner that a truck of the "roadway" type
was considered proper for classification there (495+),
whereas a truck of the industrial type was more likely to be
classified here (592+) -- in spite of the fact that this area
has not, in the past, provided recognition for the vehicular
aspect of such a truck.
540 for a self-loading or unloading vehicle having a
load-handling means which raises or lowers a load in a path
which includes vertical rectilinear movement.

(1) Note. The above-described subcombination is
classifiable here only to the extent that it is not elsewhere
provided for.
(2) Note. The line between a material handling device
proper for this Class (414) and an elevator or industrial
lift truck proper for Class 187, Elevator, Industrial Lift
Truck, or Stationary Lift for Vehicle, is as follows: (a)
Class 414 provides for load engaging structure in which the
load support surface travels in a generally vertical primary
lift direction and (1) is mounted for movement in a direction
other than the primary lifting direction (e.g.,., tilting) or
(2) has an additional load handling structure (e.g.,.,
conveyor) or (3) is constructed in such a manner that the
load support surface is inherently self-charged or
self-discharged along the primary lift direction; and (b)
Class 187, Elevator, Industrial Lift Truck, or Stationary
Lift for Vehicle provides for industrial lift trucks or
components thereof when the load is shifted in its entirety
in a primary lifting direction from one level to another
vertically spaced level and may additionally include (1) mere
pivoting or tilting of the load supporting structure for
detachment or storage or (2) retaining of a received load on
the support surface.

Subclass:

APPARATUS FOR MOVING INTERSUPPORTING ARTICLES INTO, WITHIN,
OR FROM FREESTANDING, ORDERLY LAYERED, OR MUTUALLY
STABILIZING ORDERLY GROUP:
This subclass is indented under the class definition.
Apparatus for (a) placing an article in, (b) shifting an
article relative to others within, or (c) removing an article
from a particular location in an assemblage of contacting
articles formed or taken apart at a site, wherein (A) each
article of the assemblage must at least partially sustain, or
must be at least partially sustained by, an adjacent article
of the assemblage for a portion of the time the articles are
in contact with each other and (B) the complete assemblage is
either (i) capable of maintaining its shape without support
in the horizontal direction on the articles from external
confining structure (e.g.,., receptacle walls, inclined
shelf), (ii) transportable as a unit from the site and
composed of plural articles located within each of at least
two layers* forming it, or (iii) entirely composed of
articles which would each be unsteady, or relatively unsteady
(i.e., they have a more stable attitude), if placed by
themselves in the particular predetermined location in which
they are at least partially held by the sustaining force
exerted thereon by adjacent articles.
(1) Note. See the Glossary at the end of this subclass
definition.
(2) Note. Apparatus for moving articles into, within, or
from an assemblage in which the articles composing it are all
used in their assembled form for the function they were
manufactured (e.g.,., bricks stacked to form a wall) is not
proper for this and the indented subclasses. The apparatus
proper for this area forms assemblages to facilitate either
the transporting of the articles as a unit between locations
or the storage of the articles in a nonuse position.
(3) Note. Articles in adjacent distinct levels* or layers*
of a stack* must touch each other or an article supported
separator therebetween to be considered proper for this and
the indented subclasses. Articles in a horizontally
extending arrangement which have their bottoms touching a
common supporting structure must be both touching and
intersupporting each other to be proper for this and indented
subclasses. Moreover, if the articles in the horizontally
extending arrangement utilizes vertical supporting or
confining structure (e.g.,., walls) to maintain a stable
arrangement, then to be proper for this and indented
subclasses the arrangement must be composed entirely of
articles which are in one of their less stable attitudes
(e.g.,., a sheet on its edge) in the particular predetermined
position they maintain while in the assemblage.
(4) Note. The line between this class (414) and Class 198,
Conveyors: Power Driven, relative to apparatus for placing
articles into or removing them from an intersupporting group
is as follows: Class 198 takes such apparatus when (a) it
consist of a power driven or gravity conveyor, (b) the site
on which the group is supported is a horizontally extended
conveyor surface, and (c) the group is formed on the surface
of the conveyor while the conveyor both moves and transports
the articles in a horizontal direction; and Class 414 takes
such apparatus even if it consist of a conveyor(s) proper for
Class 198 when either (a) the site on which the group is
supported is other than a conveyor proper for Class 198
(e.g.,., an elevator, a shelf) or (b) the site on which the
group is supported is a conveyor surface which has been fully
stopped while each article is added to the group.
(5) Note. The line between this class (414) and Class 221
relative to article stacking, unstacking, or arranging is as
follows: (a) Class 221 takes article piling (stack* forming)
where the pile thus formed is the supply source for a
subsequent dispensing operation (not merely the reverse
operation of the pile or stack* forming means) of the kind
provided for in Class 221; (b) Class 221 takes article
unpiling (dispensing) coming within the scope of the class;
(c) Class 414 takes article piling apparatus which is
disclosed as being capable of unpiling as well either by
reverse operation of the piling apparatus or by reverse
operation thereof together with some additional means.
(6) Note. An intersupporting group having its articles both
placed in and removed from the site as individual articles is
not considered proper for this and the indented subclasses if
the articles are (a) placed into the intersupporting group at
one location, (b) sequentially travel in a stream in the
order they are added to the group between this location and
another horizontally spaced location while being moved by
either (a) the force or gravity along a guiding or supporting
structure (e.g.,., inclined shelf) or (b) driven conveying
means, and (3) removed from the group at the second location.
Such art is classified elsewhere based on the type of
supporting or guiding structure (e.g.,., 414-150, 414-276,
414-328) or conveying means (e.g.,., Class 198, 414-564)
which exist between the two locations. However, an
intersupporting group wherein the articles therein travel
sequentially in a stream between two vertically aligned
spaced locations is proper for this and the indented
subclasses when the group is composed entirely of articles in
a stable attitude (i.e., either the group is self supporting
or could be self supporting).
(7) Note. The line between this class (414) and Class 53,
Package Making, relative to apparatus for arranging
intersupporting articles into groups for packing is as
follows: (1) Class 53 takes the apparatus when (a) a group is
formed within a final package, (b) a group formed is
subsequently directed or placed within a claimed final
package, or (c) a group formed is subsequently directed or
placed onto claimed structure explicitly designed to engage a
final package (e.g., a chute with bag supporting clip), and
(2) Class 414 takes the apparatus when (a) group formed is
intended to be subsequently, placed into a nonclaimed final
package or (b) the group formed is placed into or onto
transport structure which is not a final package proper for
Class 53 (e.g., shipping pallets).
(8) Note. The line between the art for stacking or
unstacking sheets found in this and the indented subclasses
of Class 414 and that found in Class 271, Sheet Feeding and
Delivering, was at best nebulous prior to this project
(8603M9125). During this project the classifier discussed
the line with three examiners expert in the material handling
arts (i.e., Mr. Valenza representing Class 198, Mr. Stoner
representing Class 271, and Mr. Paperner representing Class
414) and establishing the following line: (1) Class 271
provides for the stacking and unstacking of either (a)
individual sheets of unfolded paper, (b) packets of similar
sheets of paper attached together or individual folded
sheets of paper (e.g., signatures) when the thickness of each
packet or folded sheet of paper is substantially uniform and
any variation thereof is not utilized during the stacking or
unstacking operation and (c) thin, substantially flat,
nonfood articles when at least one of the articles to be
stacked or unstacked is temporarily bent or flexed during the
handling thereof; (2) Class 414 provides for the stacking or
unstacking of either (a) sheet-like food articles (b)
nonpaper, sheet-like articles (e.g., glass sheets) which are
not temporarily bent or flexed during their handling, and (c)
packets of similar sheets of paper when the thickness of
packet or folded sheet varies (e.g., wedge shaped) and this
variation is utilized during the stacking or unstacking
operation; and:
(3) Note. Class 414 also provides for the stacking of paper
sheets or sheet-like articles otherwise proper for Class 271
(i.e., 1a, 1b, and 1c of this note) when the stack formed is
subsequently handled as a unit and moved away from the
location where it was formed by handling means other than an
endless conveyor surface on which the stack was formed. All
original patents within the scope of this project have been
placed in compliance with this line. However, the patents
currently found in Class 271 have not been checked for
compliance with this line and will be screened at a later
date.

sense are set forth below with the meaning each is to have.
For economy of space, an asterisk (*) following a word
located in the definition or notes indicates that reference
should be made to this Glossary for the specific meaning
thereof.
LAYER*
A series of equal (i.e., coplanar) articles having their
bases located in a plane which extends across a stack* in a
horizontal direction relative to the support surface of the
stack*.
LEVEL*
An article within a single article wide stack* or a tier*
having its base located entirely within a plane which extends
in a horizontal direction relative to the support surface of
the stack* or tier*.
STACK*
A freestanding or orderly assemblage of superposed or
imbricated articles.
TIER*
A column of articles, a single article wide, located within a
wider stack* and extending in a vertical direction relative
to the support surface of the stack*.
Subclass:
788.1
Stack forming apparatus:
This subclass is indented under subclass 788. Apparatus
which constructs a stack* by placing one article above or
below another in contacting relationship.
(1) Note. Apparatus which first places articles into a
horizontally extending series and then tilts the series as a
unit to form a vertically extending stack* or tier* is
considered proper for this and the indented subclasses, since
the articles are placed into an assemblage and do
intersupport each other for a portion of the time they are
together. The mere tilting of an article series into a
stack* is not considered proper for this area and is found in
414-754+, since the assemblage is only reoriented and not
constructed.

(1) Note. For the purposes of this and the indented
subclasses an article separator inserted within a stack* of
articles or a pallet for supporting a stack* of articles is
not considered to be one of the stacked articles, unless the
stack* is entirely composed of separators and pallets. See
