DEFINITION

Classification: 34/179

(under the class definition) Apparatus including a stationary receptacle or tube that receives and holds the material undergoing treatment in contact with at least the receptacle or tube bottom, and has either, or both, (1) an agitator for the material within the receptacle or tube, or (2) a conveyor (other than an endless conveyor); see note (3) for causing the material to move in the receptacle or tube.

(1) Note. Complete the search in this class, subclasses 280+ for the type of apparatus classified in this subclass, and the indented subclasses, disclosed for treating feathers.

SEE OR SEARCH THIS CLASS, SUBCLASS:

165+, particularly subclass 166, for such devices in which the agitators or conveyors are vertically spaced so that the material undergoing treatment moves by gravity from one to another. Subclass 166 consists of plural apparatus similar to those classified in this subclasses (179+).

201+, for houses, kilns or receptacles in which the material does not contact the receptacle bottom, i.e., some conveyor or support for the material prevents contact with the house, kiln or receptacle bottom. Also, as between subclass 179, and subclasses 201+, all endless conveyors are in subclasses 201+.
