MOUNTING s'inucrrmans'l Fon AELECTRICAL CONDUCTORS.

citizen of the'United States, residing at Chicago,l in the county 'of Cook and State of Illinois, have invented a certain new and useful Improvement in Mounting Structures for Electrical Conductors, of which the 'fols` lowing is a full, clear, concise, and exactdescription, Vreference vbeing had to the accoinspecification. f'

The weakness in the strip of insulating material is der rahly effected liy locating weaioiied lines lietw ni :adjacent conductors, these lines being desirallly foi-ined in the n'ioliliiig operation.
