(under subclass 137) Combinations of two or more insulators, each of which constitutes a substantially complete insulating device capable of independent use as such.
(1) Note. Mere divided, sectional, or multipart insulators in which two or more insulating elements constitute complementary parts of a single insulating device are not included here and will be found in the subclasses indicated in the following notes.
(2) Note. Divided insulators are in this class, subclasses 155, 156 and 157.
(3) Note. Sectional, multi-part, and composite insulators are in this class, subclasses 178 and indented subclasses, 195, 209 and 210.
(4) Note. Mere supports for plural insulators, such as plural brackets, etc., not claimed in combination with the insulators nor otherwise restricted to use with electric conductors have been placed in Class 248, Supports, subclass 49 and indented subclasses, particularly in subclasses 67.7 and 68.1.
(5) Note. For plural supports in general, see Class 211, Supports: Racks. (6) Note. For plural insulator assemblies claimed in combination with a pole, tower, or other overhead installation, see this class, subclass 40 and indented subclasses.
