DEFINITION

Classification: 15/105.51

(under subclass 105) Implement in which one of the

independently-usable tools or instruments is an eraser as defined in subclass 424, below.

(1) Note. The combination of an eraser with a pencil or means for attachment to a pencil will be placed in subclasses 427+, rather than in this subclass. The patent must, however, claim the pencil or the attachment means in no greater detail than is necessary to define the relationship with the eraser; see (1) Note in subclass 427 for the statement of the line between this class and Class 401, Coating Implements With Material Supply, with respect to eraser-and-pencil combinations.

(2) Note. This subclass is the locus for patents to the combination of a nonmutilating eraser and a burnisher used to restore a surface, upon which an erasure has been made, to an acceptably smooth condition.
