.~ Expansible or contractible to effect work contract
DEFINITION
Classification: 118/205
(under subclass 200) Coating apparatus provided with means to intermittently alter the shape of a flexible or otherwise deformable applicator, to cause the applicator to conform to the surface of an object to be coated.
(1) Note. Some special means must be provided to directly alter the shape of the applicator. Mere resilient or flexible applicators, such as brushes or pads which deform on being pressed against the work, are excluded from this subclass, for which see subclasses 264+.
(2) Note. The solid applicator is usually (1) placed within a hollow work piece and then expanded into contact with the inner surfaces of the work piece to transfer coating material to the inner surface, or (2) contracted about the external surface of the work piece to transfer coating to that surface.
SEE OR SEARCH THIS CLASS, SUBCLASS:
214+, and 254, for other coating devices having solid applicators contacting the inner surface of hollow work pieces.
