DEFINITION

Classification: 198/300

(under the class definition) Apparatus wherein the load conveyor or conveyor system is wholly supported upon a carrier having wheels, treads, skids, or other means permitting its free movement on the ground or a floor.

(1) Note. The words "wholly supported upon a carrier having wheels, skids,. . ." in the definition of this subclass excludes a conveyor or conveying system partially sustained by such a carrier or a plurality of such carriers and partially sustained by any other support except the ground or a floor. Thus the subclass includes a conveyor support frame mounted on a carrier of the type described so that one end of said frame can slide on the ground, but the subclass does not include a conveyor partially supported on such a carrier and partially supported by (1) fixed ground supports such as stanchions or (2) a mobile carrier of a different type, such as a track traversing vehicle.

(2) Note. Assignment of a patent in this subclass or its indents does not require a claim that a conveyor is mounted on specific ground vehicle type supports such as wheels, skids, or caterpillar tracks, but may be based on any claim language indicating that a conveyor is freely movable on the ground, e.g., by claim limitations stating that a conveyor is mounted on a "carriage," "truck," "slidable support" or "movable support means," where such terms are clearly supported by the disclosure of a ground vehicle type support for a conveyor. However, a conveyor defined only as being "portable" has not been included here.
