V rent is located between adjacent turns 'of the coil as the coil is being formed. The conductor of electric current is desirably also of ribbon form either inseparate strips preferably located abreast and of arcuate formation in the final product or continuous as is the ribbon of insulating material, the two ribbons being then intertwined in the final product. v A terminal orlterminals may ex tend laterally into the conductor into con- .2 nection with the electric current conducting portion or po'rtionsthereof. The conductor of my invention has a wide variety of uses among which is its employment 'as an insulated bus bar through the insulating portions of which terminals are passed into connection with the electric current conductingportion or portions thereof. Thes terminals may be in the form of hooks which may suspend anodes in an electroplating bath.

' The invention will be more fully explained inconnection with the accompanying drawj- 'ing in which Fig. 1 is a pers ective view of one form of'conductor; and ig. 2 is a sectional view on line 22 of Fig. 1, on a larger scale. 7 7 I In producing'the insulated conductor, the ribbon of insulation 1 is wound in spiral I' fashion upon a mandrel which defines the 'bore 2 .of the insulated conductor which'is' -40hollow.'

After the conductor ment 12 has been formed, it is provided with terminals 13 extending laterally therefrom the i .7 tions 12 of the insulated conducton. ere 7" the conductoris. to be employed for suspendin anodes in an 'electro lafingbathntstermb 18 may be of hook ormatron. As I have ectric current conductingportion or withits marina @16 and rojecting thereinto into connection with g 5 r-. body applied to said terminal and dis in said practiced my invention, the holes through the conductors 12 and the holes in the ribbon of insulation that register with these other holes are larger than the terminals where these terminals-are surrounded by theconductor and insulating ribbon, tin or solder 14 being poured into the space that intervenes between each terminal and thesurrounding gibbon and conductor portions whereby these con-' ductor portions are effectively electrically connected 'with the terminals. The holes through which each terminal extends desirably occur until the bore 2 is reached, so that the solder or tin 14: may flow into the bore and surround. the inner ends of the terminals 13 to form anchoring knobs or bodies 14' 05 thereon;

It will be observed that thinconductors 12 are thoroughly encased withi insulation so as to be inaccessible to the electrolyte of an electroplating bath when such a conductor is used to support electroplating anodes.

The current conducting metallic hooks 13 may be replaced from time to time when they grehsufliciently consumed by the acid of the at Y i While the'insulated conductor of my invention is of particular usein connection with electroplatinequipment, it is obvious that it may have 0t er important uses and the ,invention is not, therefore, to be limited to any particular use to which it maybe put.

Changes may be made without departing from the invention. Having thus described my invention, I claim: An insulated conductor comprising a rib bon of insulating material spirally wound into a coil having a hollow bore, an electric current conductor disposed between adjacent I turns'of the coil, a terminal extending trans- .versely of the insulated conductor into said bore and having electric connection with said elcct'ric'current conductor, and an anchoring In witness whereof, I hereunto subscribe my name.
