DEFINITION

Classification: 34/203

(under subclass 201) Apparatus including conveyors for transporting material in plural or zigzag paths.

(1) Note. The above definition excludes the mere handling of material as by supports, trucks, tracks, or trays where no mechanical means are provided for causing the material to be conveyed while within the house, kiln or container.

(2) Note. Complete the search in this class, subclasses 646, 647, and 657, which include plural run conveyors peculiar to the handling of sheets, webs or strands.

(3) Note. For other houses, kilns or containers having conveyors, see appropriate preceding subclasses, particularly subclasses 105, 108+, 147, 576+, 611+, particularly subclasses 647+, 657+, and 658+, 164, 179+, 189, and 190.

(4) Note. For houses, kilns or containers having a single conveyor for conveying material in a single path, see this class, subclasses 201+ and other appropriate indented subclass, and subclasses 216 and 217, for plural units or compartments having handling means such as trucks and rails for moving material in single or plural paths.

SEE OR SEARCH THIS CLASS, SUBCLASS: 481, and 482+, for processes involving material speed, thickness or quantity control.
