DEFINITION

Classification: 175/19

(under the class definition) Process or apparatus including a step or means peculiar to forming a borehole in the earth without the extraction of material from the borehole, and relating primarily to the wedging or packing aside of the earth by a driven element (e.g., drive point).

(1) Note. Subject matter going beyond merely forming an opening in the earth (e.g., installing piling), is classified in another art on the basis of the additional function or structure. However, apparatus for forming or placing a lining or casing in the bore as part of the boring without earth removal operation, does not exceed the scope of this class unless significant lining or casing structure, which is classifiable elsewhere, is claimed.

(2) Note. A disclosure that the principal boring operation is carried out without earth removal is necessary to cause classification in this subclass. For example, tools which have a drive point feature (i.e., pilot or anchor), but which have additional structure that in normal operation causes, or permits material to be removed from the borehole, will not be classified herein.

(3) Note. Points that have screw or helical portions thereon which portions have a greater diameter than the largest diameter of the point will be classified under subclasses 327+ even though by disclosure no formation is removed, since any screw or helical portion would tend to convey material unless the tool was advanced the proper amount with respect to the speed of rotation.
