DEFINITION

Classification: 4/300

Flush closet:

(under the class definition) Subject matter receptacle for receiving bowel material and/or a liquid handling means to assist the removal of the bowel material from the receptacle.

(1) Note. The liquid handling can be a rapid flow of liquid or liquid to assist the removal of the bowel material.

(2) Note. The liquid can have a gas, e.g., air, added to it, the gas is usually to save the amount of water used.

(3) Note. A subcombination of basic subject matter of this subclass and the indented subclasses that is specialized for use in a flush closet is proper for this subclass and the indented subclasses unless otherwise provided for in another class, e.g., tank outlet valve, however, a tank inlet valve

is elsewhere. See Search notes below.

(4) Note. Patents issued prior to 1950 have not in all instances been classified by their claimed disclosure so the placement of these patents does not necessarily indicate lines of classification.
