DEFINITION

Classification: 174/40

(under the class definition) Structures specialized for positioning overhead.

(1) Note. This subclass and indented subclasses for the most part are for means for supporting overhead conductors, cables and conduits.

(2) Note. Insulator structures with means for securing the same to some support and/or to secure the conductor, etc., thereto are in this class, subclass 137 and indented

subclasses.

(3) Note. For overhead electrical means for transmission to vehicles, see Class 191, Electricity: Transmission to Vehicles.

(4) Note. For overhead supports for cables and conduits not limited by insulation or other claimed characteristics to electrical apparatus, see Class 248, Supports, subclass 49 and indented subclasses.
