DEFINITION

Classification: 15/395

(under subclass 393) Apparatus having bristles or other work contacting means arranged to present diverging or oppositely extending work contacting surfaces.

(1) Note. The cleaner is usually used between two work surfaces such as the slats of a "venetian" blind.

(2) Note. If a plurality of work contactors of the type covered by the above definition are assembled in a unitary device, the resulting device will be one which has opposed working surfaces in addition to those oppositely extending; this organization is not classified in this subclass but is placed above, in subclass 394.
