ABSTRACT:
To provide an improved apparatus for, and method of, applying paint to an article, particularly where it is desired that only a portion of the article have the paint applied thereto, a pump continuously supplies the paint from a storage tank to a chamber while the apparatus is in operation, with the paint returning from the chamber to the storage tank by way of an overflow pipe provided by the chamber, thereby to maintain at a predetermined level the paint in the chamber and in an associated bath in which the article to be painted is mounted. While the overflow pipe is closed by a normally open valve a displacement member is moved in the chamber below the predetermined level thereby to displace the paint in the chamber and in the bath to a level above this predetermined level with resultant application of the paint to the article. In this manner the disadvantage of a series of the articles requiring to be dipped into the associated paint bath to progressively lower levels as the paint in the bath is progressively exhausted is overcome.
