DEFINITION

Classification: 414/507

Conveyor:

(under subclass 467) Vehicles carrying some type of conveyor to load or unload them.

(1) Note. In accordance with (1) Note under the definition of subclass 467, vehicles which have conveyors or skids of the Class 193 or 198 type for loading or unloading them are classified in this or indented subclasses even though the load is not shifted from the conveyor or skid.

(2) Note. This area represents a revision of subclasses 83+ of former Class 214 to the extent of adding subclasses 509+ (derived in large part from former subclass 82) and reclassifying subclass 529 (formerly subclass 84). While subclasses 518, 521, and 525 (formerly subclasses 83.14, 83.22 and 83.3, respectively) have been screened for subject matter for subclasses 509+, subclasses 507, 508, 518 to 528, 537, and 538 are otherwise unchanged from their predecessor

subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

491+, for a self-loading or unloading vehicle having a load-receiving portion which is pivotable relative to the horizontal, and having also a driven means to move a load relative to the portion.

502+, for a self-loading or unloading vehicle wherein the load-handling means comprises two or more power-driven conveyors which engage the load successively.

813, for a process of charging or discharging a self-loading or unloading vehicle including a conveying means. SEE OR SEARCH CLASS
