DEFINITION

Classification: 99/600

(under subclass 584) Device including grain hulling*.

(1) Note. This subclass is a locus for reciprocating, solid (nonperforated) grain-hulling members.

(2) Note. Excluded from this subclass are mere tumbling devices (i.e., rotary drums or other moving receptacles which present no abrasive or other material removing surface to the grain) for effecting mutual abrasion only between the grains for hulling or cleaning, such devices being classified in the appropriate subclasses of Classes 51, 366, or other appropriate classes in accordance with the line between those classes. However, receptacles, whether moving or stationary, when provided with relatively movable grain contacting members which move the grain in the receptacle for the purpose of removing the husk or adhering impurities (see (3) Note.), are provided for in this class even though the action on the grain is limited to mere mutual abrasion. Combinations, which include both mere mutual abrasion by tumbling in a moving receptacle and the use of an abrading or other material removing surface, are provided for in this and the indented subclasses.

(3) Note. Most of the devices classified in this or the indented subclasses are for the purpose of removing husks, skins, or other naturally occurring integuments from grains. However, because of the similarity of their structure to hullers, cleaners (to remove adhering impurities) are included when the cleaner is of such a nature as to subject the grain to an appreciable rubbing, abrasion or impact action by a solid work treating surface or agent. Cleaners not involving appreciable abrasion or impact action will be

found in the generic cleaning Class 134, Cleaning and Liquid Contact With Solids, or some other cleaning class according to the notes appended to the class definition of Class 134.

SEE OR SEARCH THIS CLASS, SUBCLASS:

488, for a grain-hulling device having automatic control. 518+, for a grain-hulling device which includes noncleaning, nonhandling, fluid contact with the grain or grain part.

SEE OR SEARCH CLASS

15, Brushing, Scrubbing, and General Cleaning,

3.1+, for grain cleaners employing the instrumentalities provided for in that class, e.g., brushes and wipers. See subclass 620 of this class (99) for hullers employing brushes or wipers.

134, Cleaning and Liquid Contact With Solids, see (3) Note above.

241, Solid Material Comminution or Disintegration, for grain comminuting devices having structure similar to the devices classified herein and for combinations of grain hullers of the type classified here, with comminutors (see

7, and 101.01 of that class). Since most of the hullers classified here inherently divide the husk or adhering impurities into a number of pieces in the process of removal from the grain, only such devices as effect the division of the grain body (endosperm) into a plurality of parts should be considered comminutors or comminutor-huller combinations for Class 241.

366, Agitating,

219+, for movable mixing chambers, and subclasses 241+ for stationary mixing chambers with movable stirrers having general utility as described in (2) Note above.

451, Abrading, for an abrading process or apparatus of general application. For example, included in Class 451 is a grain tumbling device which presents no abrasive or other material removing surface to the grain wherein abrading is effected by mutual engagement of the grains with each other. However, note that a grain container that is either stationary or moving is included in Class 99 when provided with a grain contacting member which moves the grain in the container for the disclosed purpose of removing the husk or adhering impurities, even if using an abradant.
