THEODORE GUILLEAUME, OF MLHEIMON-THERHINE, GERMANY.

ELECTRIC CABLE.

SPECIFICATIQN forming part of Letters Patent No. 514,925, dated February 20, 1894.

Application filed October 6, 1893. Serial 110.437,321. (No model.) Patented in France April 14, 1893,1lo. 220,891: in Belgium April 14, 1898, No. 104,271, and in Italy August 8, 1893, XXVII, 34,551,11XVII, 473.

To @ZZ whom it may concern:

Be it known that I, THEODOEE GUIL- LEAUME, a subject of the German Emperor, residing at Miilheim-on-the-Rhine, in the German Empire, have invented new and useful Improvements in Electric Cables, (in respect whereof I have obtained Letters Patent in France, No. 220,891, dated April 14, 1893; in Belgium, No. 104,271, dated April 14, 1893, and in Italy, XXVII, No. 34,551 and LXVII, No. 473, dated August 8, 1893, and for which I have applied for but have not obtained Letters Patent in the following countries, to wit: Great Britain, No. 7,782, under date April 17,1893; Germany, No. 6,789, under date May 6, 1893; Sweden, No. 602, under date July 22, 1893; Austria-Hungary, under date July 31, 1893; Switzerland, No. 8,187, under date October 20, 1893, and Russia, No. 11,845, under date August 25, 1893,) of which the following is a specification.

This invention relates to electric cables or conductors embodying one of the principal features of my invention formingthe subject of Letters Patent No. 483,285, dated September 27, 1892.

In the accompanying drawings, Figure 1 is a transverse section of a cable made in accordance with the present invention and adapted for use in the three-wire system. Fig. 2 shows a similar cablein which the component wires are of different shape. Fig. 3 represents a cable suitable for employment in the tive-wire system; the protective sheathing being utilized as the fifth conductor. In Fig. 4, the fifth conductor consists of a group of wires placed outside the exterior insulation. In Fig. 5, the iifth conductor is a single wire in the center ot the cable.

The cables particularly described with reference to the drawings forming part of the speciiication to the aforesaid Letters Patent are principally intended for telephonie and telegraphic transmission.

The object of the present invention is to produce cables or conductors to some extent similar in character, but specially adapted for electric light service or transmission of power on the three-wire or the live-wire systems, wherein the formation of air-spaces is of less practical importance; a special advantage of the present method of construction being that several conductors of unequal sectional area may be readily united to produce a compact cylindrical cable, the manufacture of cables of this class having hitherto presented considerable difficulty.

According to one mode of carrying out this invention, three conductors a, a and a2 for use in the three-wire system and a body of insulating material c, three-armed in transverse section, are twisted together, the several conductors lying in the respective grooves of the insulating material c, and being thus separated from one another. Each conductor a, d orc2 may be a strand comprising any suitable number of wires of any appropriate transverse section or sections. The insulating strip or body c and the conductors of., o/ and a2 twisted therewith are surrounded by exterior insulation CZ, which may be protected by sheathings c and f of lead, hoop iron or other material.

In a cable adapted for use in the vewire7 system, the two principal conductors a3 and at and the two secondary conductors c5 and a@ may consist of strands of wire, as shown in Figs..3, 4 and 5. In Fig. 3,the protective sheathing c serves as the fth conductor; economy in first cost being hereby attained. Or, the fifth conductor may be formed of single wires al placed equidistantly around the exterior of the insulating envelope d, as represented in Fig. 4, and twisted together with the main conductors and insulating material. Or, the fifth conductor may consist of a single wire a8 arranged in the center of the cable, as illustrated in Fig. 5.

That I claim as my invention, and desire to secure by Letters Patent, is-

1. For electric light service or transmission ot' power, a cable circular in transverse section but comprising a body of grooved insulating material irregular in transverse section,

and several conductors of unequal transverse section twisted together with the insulating material, each groove in the insulating material being just large enough to hold the conductor lying within the same, substantially as set forth.

2. For electric light service or transmission ICO of power, a cable circular in transverse section but comprising a body of grooved insulating material irregular in transverse section, main and secondary conduotor3 of unequal transverse section twisted together with the insulating material, each groove in the in- 'sulating material being just large enough to hold the conductor lying within the same, and a fth conductor separated from the other conductors by insulating material, substantially as set forth.

3. For electric light service or transmission of power, a cable circular in transverse section but comprising a body of grooved insulating material irregular in transverse sec- THEOD ORE GUILLEAUME.
