ELECTRICAL CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 286,963, dated October 16, 1883.

Application filed May 23, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS S. Itmm, a citizen of the United States, residing at Bridgeport, in the county of Fair-field and State of useful Improvements in Electrical Conductors; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvements in electrical conductors, and. has for its object to do away with the in sulating of the positive and negative conductors separately, and then confining them by braiding or otherwise, thereby making a double cord; and with these ends in view my invention consists in flexibly arranging and insulating both electrodes around a common center, and providing them with suitable tips at their extremities, as will be hereinafter fully and in detail explained, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may more i'ully understand its construction and adaptation, I will proceed to describe the same in detail, referring by letter to the accompany ing drawings, forming a part of this specification, in. which Figure 1 illustrates the several steps in the construction of my improved conductor, and Fig. 2 is a view showing the arrangement and relation of the electrodes where they branch or fork, for the purpose of being connected to the positive and negative poles of any electrical instrument.

Similar letters denote like parts .in both figures of the drawings.

A is a flexible core, around which is braided or otherwise arranged conducting material B, preferably tinsel. This tinsel may form either the positive or negative electrode, and is insulated by any suitable flexible material, C, and again around this insulator is braided, or in any suitable way arranged, another layer of tinsel, D, which will form. the positive or negative electrode, the case may be, and the whole is enveloped by an outer flexible covering of insulating material E. It will be seen that an electrical conductor formed in this way will have ahigh degree of ilexibilitywithout decreasing its conductivity.

IVhen it is desired to connect the two electrodes of the conductors with the correspond ing poles of an instrument, the inner insulated electrode is continued on, and the outer electrode is braided or suitably arranged around an independent core, A, and insulated by a continuation of the material E, as will be readily understood by reference to Fig. 2. The electrodes are then provided with ordinary tips, F. I am enabled thereby to provide an electricalconductorexceedingly flexible, which is a great advantage, since the do u ble cords now in use are very stiff, and they invariably twist and become tangled by usage. My improved conductor presents the appearance oi'a small, round, and neat cord, and is entirely different from the bulky and iiat cord now in use.

RVhile I have described the prelerable construction of my improved conductor, I do not limit myself to any particular conducting ma terial; also, the core A may be dispensedwith, thereby reducing the size of the conductor; also, I am enabled to make my improved conductor triple, quadruple, &c., by simply braiding or arranging the several conductors and insulators in the manner described and providing them with suitable tips, the proper electrodes being distinguished by different colors of insulating material.

I am aware that it is not new, broadly, to arrange the electrodes with properinsulators around a common center, and I do not wish to be understood as laying claim to this construetion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an electrical conductor, a series of ilexi ble strands composing one electrode, braided or otherwise arranged around the insulator of 95 the other electrode, in combination with suit able tips secured to the extremities of the electrodes, substantially as set Forth.
