.~ With conductor receiving aperture or bushing type
DEFINITION
Classification: 174/167
(under subclass 137) Devices in which the insulating body is provided with at least one through aperture for receiving a conductor.
(1) Note. Insulating tubes, spools, and other bushing type insulators, other than divided insulators, not claimed in combination with a wall, plate or other holding means, or restricted by structure to use therewith, have been placed in this subclass.
(2) Note. For other insulators having through apertures for receiving conductors, see this class, subclass 151 and indented subclasses, for bushings mounted in a wall or plate or restricted to use therewith; subclasses 154 and 155, for insulators mounted in an embracing holder or restricted to use therewith, and subclasses 155, 156 and 157, for divided insulators.
(3) Note. For insulators having through apertures for receiving supporting or terminal elements, see this class, subclasses 157, 166, 184, 207, and 208.
(4) Note. For insulators having slots and grooves for receiving conductors, see this class, subclasses 174 and 175.
