DEFINITION

Classification: 172/786

(under subclass 781) Apparatus in which there are a plurality of scrapers.

(1) Note. Plural scraping blades secured to a backing member or members to form a unitary means are not considered to be plural scrapers, the whole assemblage being considered a single scraper.

(2) Note. A plurality of scrapers may comprise any combination of parts (other than described in (1) Note) if two or more of the parts are each identifiable individually as constituting a scraper. A V scraper, for example, is considered to comprise two scrapers if each arm of the V fits the definition of a scraper.
