DEFINITION

Classification: 414/539

Loading or unloading by other carrier or mover means and the load movement thereof:

(under subclass 467) Apparatus wherein the load handling means comprises a carrier or mover of a kind not provided for above, and wherein the movement imparted to a load or a load holder by such a carrier or mover is utilized as a basis for

subdividing the art.

(1) Note. The art of this and the indented subclasses came, for the most part, from subclasses 75, 77 through 80, 82, and 85.5 of former Class 214. While most of those subclasses were superior to subclasses 506+ (former subclasses 83+), it appears advisable to move this area (539+) below that one until the art of that area (506+) can be reviewed.

(2) Note. Inasmuch as the previously existing breakdown of the art of this area by the type of loading or unloading device (e.g.,., elevator, vertically swinging load support, etc.) did not appear to avoid the scattering of structurally related devices, it is considered that a more meaningful breakdown of the art may be achieved by giving primary consideration to the path of movement of the load or load holder.

(3) Note. The movements referred to in this and the indented subclasses are those which are performed for an operational purpose, except where the contrary (e.g.,., for the purpose of storing the load holder) is indicated.

(4) Note. Inasmuch as a carrier having track-guided wheels is not considered to be a conveyor-type carrier, it is placed in this and the indented subclasses rather than in subclasses 506+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

486+, and 491+, for a vehicle having a load receiving portion which is pivotable relative to the horizontal and wherein, in the former subclass, the vehicle includes means to raise a load above the portion for deposit thereon or therein, and, in the latter subclass, the vehicle includes driven means to move a load relative to the portion.
