(under the class definition) Apparatus comprising means other than a scraper specially intended for working the earth adjacent a fixed structure on the surface of the earth (e.g., a paved walk to edge a lawn) or working the earth adjacent a turf surface (e.g., grooving a plant bed adjacent a lawn).
(1) Note. This definition is intended to provide an art collection of lawn edgers or trimmers. Usually such devices comprise a means for guiding the device along the edge of the pavement. However no special structure need be claimed for classification in this subclass. Patents whose sole specific disclosure or whose claims relate to the described use are considered to come under this definition.
