DEFINITION

Classification: 405/154

PIPE OR CABLE LAYING, RETRIEVING, OR UNDERWATER MANIPULATION:

(under the class definition) Method or apparatus comprising a step or means for placing a conduit or a string of relatively slender material beneath the surface of the earth or a body of water, recovering the same therefrom, or handling a string or conduit below the surface of a body of water.

(1) Note. For classification under this definition either (a) a step or means for submerging the pipe or cable beneath the surface of a body of water must be claimed, or (b) a step or means for forming an earth opening or otherwise handling the earth material must be claimed.

29, Metal Working, appropriate subclass for an assembling process or apparatus.

37, Excavating, appropriate subclass for a means to form a trench.

111, Planting, appropriate subclasses for a process or device for agricultural-type planting. 138, Pipes and Tubular Conduits,

97+, for a process or means for repairing a pipe or tubing, and including a step of excavating to reach the defective area of pipe or tube; subclass 108 for an underground pipe or

conduit for pipe.

166, Wells,

376, 377, and 378+ for placing, removing, constructing, or assembling well elements.

174, Electricity: Conductors and Insulators,

37+, for underground electrical installations; and subclasses 68.1+ for electrical conduit structure.

175, Boring or Penetrating the Earth, appropriate subclass for a process or means for forming a bore. The mere description that the tubing or the like which is used in the boring operation, is left in the earth, does not preclude classification in Class 175. See the class definition of Class 175 for the line between Class 405 and Class 175.

404, Road Structure, Process, or Apparatus, particularly

2, for conduits combined with pavement curb or gutter structure.

414, Material or Article Handling,

745.4+, for apparatus for laying pipe without earth handling or excavating means.
