Click here for a printable version of this file

SECTION I - 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.

SECTION II - 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.

(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).

 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.

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.
  
[List of Patents for class 414 subclass 230]    230Caused to pivot by advancing vehicle:

 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.

(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.
  
[List of Patents for class 414 subclass 235]    235Supporting member separable from endless, member-transporting carrier, or disengageable from endless drive means, and movable away therefrom for receiving, discharging or storing vehicle:

[List of Patents for class 414 subclass 239]    239One 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.
  
[List of Patents for class 414 subclass 240]    240Member moving from particular location to discharge and/or receive vehicle, and returning thereto:

(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.

[List of Patents for class 414 subclass 467]    467SELF-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.

[List of Patents for class 414 subclass 469]    469With load-receiving portion, or significant section thereof, pivotable relative to horizontal:
 This subclass is indented under subclass 467.  Apparatus wherein the handling means comprises enabling the load-receiving portion, or at least a significant part of the portion, to move in an arcuate path relative to a generally horizontal plane, and thus impart a change in the attitude of the portion relative to that plane, for facilitating the loading or unloading of the vehicle.
(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.

(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.

(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.

Repetitive terms used in the titles or definitions of this subclass and its indented subclasses in a special or limited 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.

[List of Patents for class 414 subclass 788]    788APPARATUS 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.

[List of Patents for class 414 subclass 788.1]    788.1Stack 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.
