(under subclass 137) Insulating devices having means for holding or securing one or more conductors.
(1) Note. For insulators having means specially designed for holding structures or articles other than conductors, see this class, subclass 138.
(2) Note. For insulators combined with conductor holding means specially designed to electrically connect two or more conductors, see this class, subclass 145.
(3) Note. For devices for holding conductors on insulators not claimed in combination with the insulator nor otherwise restricted to use with electric conductors, and for analogous devices for holding cord and rope, see Class 24, Buckles, Buttons, Clasps, etc., appropriate subclasses, especially subclasses 115 and 339+ and their indented subclasses.
(4) Note. For insulators combined with means specialized for holding either overhead or underground conductors, such as trolley wires or third rails, so as to permit travel of a current collector therealong, see Class 191, Electricity: Transmission to Vehicles, subclasses 32 and 42.
(5) Note. For analogous devices for securing the wires of wire fences to the fence posts or poles, see Class 256, Fences, subclass 47 and indented subclasses.
