(under subclass 400) Coating apparatus having a receptacle or tube for containing the coating fluid the level of which is kept constant by (1) a tube of capillary dimensions for conducting fluid to the receptacle from a source of supply, or (2) the liquid supply chamber, otherwise sealed, has an outlet leading to the immersion receptacle, which outlet is closed by liquid accumulating in the coating receptacle to stop flow thereunto except when material is removed from the coating receptacle whereupon an amount corresponding to that removed is thereby permitted to flow out of the supply chamber to replenish the coating receptacle.
(1) Note. This subclass does not include absorbent or porous pads or brushes which may use capillary action to conduct or convey coating material, and for such subject matter search the solid applicator subclasses referenced in the search
notes below.
