DEFINITION

Classification: 209/339

(under subclass 333) Flat horizontal or inclined sifters supported for swinging movement, generally on hangers or standards, the movement being in one horizontal direction where there is no definite travel of material over the sifter to discharge, or, where there is such travel, in a horizontal direction transverse to the direction of travel.

(1) Note. The slight incidental vertical component of motion due to support by standards or hangers is disregarded in connection with devices placed in this subclass; but where the hanger or standard construction is such that there is a marked and material vertical component of motion the device generally is classified elsewhere (see Search This Class, Subclass, below) Where there is both sliding support and swinging (hanger or standard) support, the device is placed according to the sliding support.

SEE OR SEARCH THIS CLASS, SUBCLASS:

327, for a hanger or standard construction such that there is a marked and material vertical component of motion (see (1) Note).
