DEFINITION
Classification: 172/784
(under subclass 781) Apparatus including an earth working element which differs in size or shape from the scraper and so is diverse, the diverse element being capable of working the earth at the same time as the scraper or adjustable in the apparatus to work the earth alternatively to the scraper.
(1) Note. A diverse earth working element under this definition may comprise any distinctly different portion of the scraper which causes classification under the definition of subclass 781.
(2) Note. A wing or vertical plate which extends longitudinally and acts to confine earth loosened by a scraper or other earth working element is not considered a diverse element under this definition.
(3) Note. An earth working element which differs from another by being merely a mirror image, e.g., for pushing earth to the left instead of the right, is not considered diverse under this definition.
(4) Note. The difference between the earth working element and the scraper does not have to be claimed. If a claim refers to an earth working element which is disclosed as diverse, this is sufficient for classification under this definition.
