Be it known that I, RUSSELL SPAULDING, a citizen of the United States, residingin the borough of Manhattan, city, county,and State useful Improvements in Electric Conducting- Cables, of which the following isaspeeification I i My inventionrelates to electric-current- I will describe an clectric-current-condncting, cable and then point out the novel features thereof in the claims. v

In the accompanying drawings, Figure 1 is a detail plan view of a conducting-core employed in the cable einlmdying my-invention. Fig. is an end view'of Fig. 1. Fig. 3 is a detail plan view of a condu etor-cable embodying my invention. Fig. -l is an end view of Fig. 3. Fig. 5 is a detail plan view of a modified form of conductor-cable embodying my' invention. F'g. 6 is an end view of Fig. 5.

Similar letters of reference designate corresponding parts in all of the figures.

being considerably wider than it is thick; and it consists, essentially, of a core A and an insulating-covering A. The core A consists of plurality of fine wires, which are braided. "The line wires are preferably arranged in strands each consisting of a number of wires and the strands braided. In making the core A it is braided about a mandrel or other iormmjanrl it iseylindrical. ln its cylindrical 55 shape it is passed through suitable rolls and flattened. ltinaybeflattenedbyotbermeans. 7 The insulating material, which is preferably of rubber, may be applied atgthe time the core isbcing lath-med by rolls. it may, however, i

be applied in any desired wail. l

, p w Application filed Piabrdarjfi/IQOZ. Serial No. 92,667. (No model) In Figs. 5 and-6 I have shown a modified form 0E e'onduetm'. .It consists of a plurality of eorsA, inclosed by a: single insulatingcovering'flk'. ,1 have shown two cores; but it is obvious thatany number. maybe inelosedq 5 .by a single insulating-covering. Between each core'a vertical wally.- of insulation is placed. The wall is preferably integral with the other adjacent parts of the covering.

Acable made inthis manner possesses great tensile strength and is extremely flexible.

\Vhat I elaim as myinvention is-' 1. An electric conductor-cable comprising a braided core and an insulating-coverin 2. An electric conductor-cable comprising a core-andan insulating-covering, said core consisting of a plurality of wires arranged in strands, which are braided. v

23. .An electric conductor-cable comprising a plurality of braided cores, and a single insulatingcovering for said'cores and which also insulates the cores one from the other.

4. An electric conducting-cable comprising a plurality of braided cores arranged parallel to each other and in the same horizontal plane, 0 5
