DEFINITION

Classification: 414/467

SELF-LOADING OR UNLOADING VEHICLES:

(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.

SEE OR SEARCH THIS CLASS, SUBCLASS:

333, 334+, 337, 338, 339, 340+, 349+, 352+, 354+, and 373+, for various combinations of one or more, moving or stationary, wheeled (except that subclass 373 omits this limitation), load-transporting type vehicles, and an external means of some nature for loading or unloading, or cooperating in the loading or unloading of, the vehicle. Also see (3) Note, above for a further explanation of what may comprise an external means for these subclasses (333, etc.). 430, for a vehicle having a ramp for directing a wheel onto the vehicle.

434+, for a vehicle having a loading mechanism which is motivated by motion of the vehicle.

444+, for vehicles which have grasping or hooking means and tilt in order to pick up a load for transportation.

458+, for vehicles which receive a load within them and have load-handling means comprising spaced shelves.

460+, for vehicles which straddle the load for loading the vehicle.

462+, for a vehicle having a movable carrier or support for an auxiliary load, which load is in addition to the vehicle's primary load.

618+, for vehicle with an elevating carrier comprising a grab and in which there are no additional handling means for depositing or removing a load from the grab.

680+, especially 728, for vehicles with vertically swinging load supports which pick up and transport material without transferring it.

812, for a process of charging or discharging a self-loading or unloading vehicle.

37, Excavating,

304+, for a vehicle having means for excavating material and for loading itself with the material. 105, Railway Rolling Stock,

239+, for railroad vehicles having means thereon for producing a gravity dump of the vehicle contents.

108, Horizontally Supported Planar Surfaces,

51.11+, for an industrial platform.

212, Traversing Hoists, appropriate subclasses for vehicles having a traversing hoist capable of transferring a load from one location external of the vehicle to another external location, and also capable of depositing a load on an extension of the mounting platform.

244, Aeronautics,

137.1, for devices and arrangements for loading or unloading a vehicle of the aircraft type, which devices, etc., may include means for moving a load to or from the aircraft.

254, Implements or Apparatus for Applying Pushing or Pulling Force,

2+, for vehicles having a platform load support and mechanism for raising and lowering it; and subclasses 279+ and 325+ for vehicles having at least one rotatably driven drum for pulling on a load hauling or hoisting cable.

280, Land Vehicles,

401, for articulated vehicles so constructed that one section thereof is movable to a position upon another section for transportation thereby, and subclasses 47.12 and 47.17+ for vehicles loaded by mere tilting of the vehicle body as in the common hand truck. 298, Land Vehicles: Dumping, appropriate subclasses for roadway vehicles in which the unloading is effected by mere tilting of the vehicle body, or by combined sliding and tilting, etc., or where effected by unlatching or withdrawing of gates or doors or other like gravity unloading means; see also the reference to Class 298 in

469, of this class (414).
