(under the class definition) Apparatus wherein the excavator includes an excavating tool properly classifiable in this class in some way mounted or structurally arranged for use along with another tool which may be either a tool of this class or a tool of another class not superior to this class or in which the excavator includes a tool properly classifiable in this class which is particularly adapted to be changed or modified in some way, or rearranged in some manner, so as to either be used as a different type of tool or to effectively become a different type of tool.

(1) Note. Class 37 is superior to Class 172; therefore, the combination of a Class 37 tool with a Class 172 tool is proper for this subclass.
(2) Note. Class 37 is superior to Class 414; therefore, the combination of a Class 37 tool with a Class 414 tool is proper for this subclass.
(3) Note. For a proper placement of a patent for this subclass, at least one claimed tool must be of the Class 37 type.
(4) Note. The change in the apparatus must be more than merely placing a part in one of a series of adjacent holes or in general making a change which amounts to only an adjustment or a minor alteration in the overall functioning of the device.
(5) Note. The change must be more than to change a part between an operative and an inoperative position.
(6) Note. If one of the tools is used in snow removal, it should be classified in this class, subclass 241, and
cross-referenced in this subclass. SEE OR SEARCH CLASS
