WERE CABLE.

Specification of Letters Patent.

Patented Mar. 10, 1914.

Application filed October 8, 1912. Serial No. 724,788.

7 once being had therein to the accompanying drawings, forming a part of this specifica- My invention relates to metal cables which tric'currents, and its Objects are to provide cables that are light in weight, strong, readily flexed, stable in structure, and have free surfaces of unusual extent.

In the accompanying drawing, which forms a part of this specification, Figure 1 is a cross sectional view and Fig. 2 is a side view of a single strand, used in the various Combinations forming my cable or rod, consisting offiat wire or relatively thin metal strip twisted about its own axis into augerlike form. Figs. 3, 4:, 5, 6 and 7 are cross sectional views of the more simple forms of construction of my rod, where two or more of the single strands (Figs. 1 and 2) are twisted or laid together spirally. Fig. 8 is a cross sectional view at a, Fig. 9, of a cable or rod composed of a four strand cable (Fig. used as a core, covered with ten strands laid spirally about said core, forming a cable or rod of fourteen strands. Fig. 9 is a. side view of the same with a portion having the outer covering strands removed to show the core. Fig. 10 is'a cross sectional view of the cable at Z) Various other combinations of strands may be made composed wholly of spiraled, metallic, flat wires or strips, or in combination with strands of other forms, to form the cable or rod.

' The form of the metallic wire or strip as vhown in Fig. 1 is approximately a parallelogram with rounded edges. but I-do not limit myself to that particular form, as the some lQHiltS may be obtained if the sides are curved or indented, the essential feature being that the width of the metallic wire or strip shall materially exceed its thickness.

It is evident that by the use of a spirally twisted, flattened wire or strip, in the place of a round wire of diameter equal to the strips width, in any of the above combinations forming a cable or rod, the size of the cable or rod will remain the same, the metallic surface and flexibility will be increased, and the weight of the cable or red reduced to one-fourth'(or even less) of its original weight, depending upon the thickness of the flattened metallic wire or strip.

I am aware that a spirally twisted flattoned metallic wire or strip as shown in Figs. 1 and 2 is not novel, and also that it has been used as a core in a cable or rod, as in my former Patent No. 675116, dated May 28, 1901, but so far as]: am aware it never has been used as a component element of the cable itself, by being twisted or laid spirally with other elements or strands to form a cable or .-rod.

I do not limit myself to the use of any particular metal in the construction of my rod or cable, either wholly or in part, nor in the length of pitch or direction of the spirals in the single spiraled strand.;or any combination of strands in forming my cable or rod.

Having fully described my invention, I claim and desire to secure by Letters Patent:

1. A series of relatively thin metal strips each twisted about its own axis and all united, with their broader surfaces free from each other, to form a metal cable.

2. A cable for conducting electric currents, consisting of a series of relatively thin metal strips, each twisted to auger lilte form. lying side by side with their edges only in Contact and together forming a cable cylindrical'in general shape.

In a flexible cable for transmitting electric currents, the combination with a central core member, of a series of members each consisting of a iiat strip twisted to augerlike form and all passing spirally about said core member to form a cable.
