Y More specifically, our invention is directed to awcable constructionin which the rubber insulation is protected against corona action i by the use of a'n imperforate conductor coat- 1 ing applied tothe surface of the rubber insu;-

' Our invention may take several forms, depending upon the character or construction of the cable to which the invention is applied, and in the accompanying drawings we have )shown several embodiments of our invention by way of illustration.
More specifically, however, our invention provides an imperforate flexible conducting or conductor coating on the outer surface of the rubber insulation ofthe conductor, vthis conducting coating being inthe form of i metal deposited on the insulation so as to be in intimate direct contact therewith throughoutthe entire area of. the surface of the insulation,
thus affording an adherent imperfora-te conducting surface which can be grounded re dw ily, and a constructionin which tbefvolu e.
cation:
Figal shows one embodiment of. our invintioninsectional elevation i .F ig. 2-is a cross section of the cable of Fig. 1 and Fig. 3 is a'view similar to Fig. 2 of another elnbodimentpfl our invention. y
f Referring first of all to Figs. l and'2, 1 designates the-conductor of asingle conductor cable, the conductor being either ofthe solid or stranded copper type. Immediately surrounding the conductor 1 is a rubber compound insula t ion(2. Upon the exterior of the rubberr compound insulation-2 is an adherent imperforate lex'iblef conducting surface of metal designated 3, such as lead, zinc, aluminum, tin, etc., or any 'other metal'that confmercially is used as ali`elctric conductor. This conducting surface is in direct intimate contact with the surface ofthe insulation throughout. Toj obtain this direct and intimate contact of the conducting rsurface or layer 3 with thesurface of the rubber insulation 2 the metal is applied in a heated atomized condition .to the surface of the insulation, as, for example, by the processes (if the Schoop PatentNo. 1,256,599 of February 19',
1918 or the McCoy Patent No. 1,268,030 of i May 28 1.918. "By employing thoseor similar processes not'only is-the metal conducting surface in direct 'and intimate contact with the compound constituting the insulatlon, but the metal even becomes embedded in the insulation.` This eliminates all danger of@ entrappin'g air between the insulation and the conducting layer and hence by grounding this conducting layer, as shown at G', practically all corona cutting is eliminated.
Over the outside of this metallic conducting surface We apply a tapev designated 4 which may be the usual rubber treated tape employed in cablemanufacture and over this tape we apply, for example, a braid cover- 5.1: Y Insorne instances we elect to apply a con; ductive metal coating to one face of the tape 4,' which when the tape is applied will be wound directly over the'conducting surface 3. In this connection we wish it to be noted that if the'tape' is to "be metal coated or to have a metallic conducting coating applied theretb, this fs'urface is preferably applied by the' same method employed in applying the lation electrical conductivity is further inmentioned conductorcoating, and avprote-ctive coating over said tape This specification signe anuary, 1930,

creased with a further reduction in corona cutting. -L ,K While thel embodiment of our `invention shown in Fig. V1 -is directed to the construction of asingle conductor cable, either of the stranded or solid conductor type, it isto be understood, as pointed ont above, that our invention is applicable to multiple conductor cables as well, and inFig. 3 we have illustrated a three conductor cable.
2 In this embodiment of our invention, the-y conductors are designated 6, 7 and 8, respectively. Each Aconductor is covered with an insulating rubber compound designated 9 on which is sprayed a continuous unbroken im-A periorate ilexible metallic conducting layer v10. About this conducting surface or layer we apply a tape 11 which is'- preferably,
J though not necessarily, of the metal sprayed type above referred to. The voids between 359 the three structuresthusformed are filled with jute designated 12 orother sju'table material to build up a circular crossl section, and
then about the entire mass is applied rubber iilled cotton tape designated' 13. On the exterior of this tape we apply a lead Sheath 14,
or this sheath may bearubber, braid, Vor a sheath known, commercially as submarine armor. P Y' In all cases it will be understood that when the cable is in use the imperforate flexible conducting surface or conducting layer immediatly over and in intimate direct contact with the insulation is grounded.
It willbe understood also that we have, for
in combination an electric conductor, insu1a- -tion about the same, a continuous adherent imperforate conductor coating, to be ground l ed, on the exterior surface of theinsulation,
*a rubber filled tape about the' conductor coating, a conductor coating- 011 one face of saids tape, the tape being applied-sothat said cond doctor `coating is 1n 4contact with said first ,u the lurposes'of illustration, exaggerated the FRED HENDEY.
