DEFINITION

Classification: 166/67

(under the class definition) Devices comprising means intended to function and remain above ground level combined with means intended to function in the well below ground level.

(1) Note. Some specific feature of both the above ground level and below ground level means must be recited in a claim for classification of a patent in this or indented subclasses. The mere recitation of a cable, pipe, rod, tubing or casing for insertion in a bore hole is not sufficient. Above ground level apparatus combined with such features will be found in subclasses 75.11+ or in other subclasses, according to the subject matter involved.

(2) Note. The mere recitation by name only of a pump above ground for inserting a treating or circulating fluid is not sufficient for classification of a patent in this or indented

subclasses. Such patents are classified on other characteristics.

(3) Note. See subclass 75.11 for the meaning of ground level in this definition.

335+, for a well which is above ground but below water. Note, however, that a well device which is disclosed as being under water but in which no claim is made to a feature peculiarly adapting the device to function under water is considered as if the water were not present and is classifiable in subclasses 67+ if it otherwise meets the definition of subclass 67. 51, for above and below ground apparatus for placing gravel.

52, for above and below ground apparatus associated with a plurality of wells.

53+, for above and below ground apparatus with automatic means.

57+, for above and below ground apparatus for heating, refrigerating or with heat insulating means.

64, for above and below ground apparatus with time or distance measuring, temperature responsive or counting means.
