INDUCTION-COIL.

SPECIFICATION forming part of Letters Patent No. 342,947, dated June 1,1886.

Application filed January 12, 1886. Serial No.189,333. (No model.)

Initter. Here F is the core and G the pri- 4o mary coil,wound in the usual way. The secondary wire is wound in multiple are, as illustrated in Fig. 2. The line connects with the terminals of the helices designated by the numbers 2 at 6 S 10. The other terminals of My invention relates to a coil for receiving induction from or causing induction in a neighboring conductor, and in the method of consaid coils are attached to the conducting-wire -D, which at its opposite extremity connects with the terminals of the helices 1 8 5 7 9,

hereinafter more particularly set forth.

Figure l is a diagram illustrating the constructionofmyimprovedinduction-coil. Fig. 2 is a diagram showing the disposition of the helices as arranged in Fig. l in the coil. Fig.

which alternate with the helices 2 4t 6 8 10. The opposite terminals of the helices 2 4 6 8 5o 10 communicate with ground.

I do not limit myself to the application of my invention to induction-coils solely, because it may well be adapted to thewinding of armatures of electro-magnets. Neither do I limit myself to an induction-coil having a secondary helix constructed as hereinbefore set forth, because I may so construct the primary helix, winding the secondary helix in the usual manner, or I may arrange both secondary and primary helices according to my invention.

I claim A compound coil for inducing a current in or receiving a current by induction from a neighboring conductor, containing a set of helices arranged in in utiple arc in a main c011 ductor, and a second set of helices similarly arranged in the same conductor, each helix of one set alternating with a helix of the other set, all of said helices being wound in the same direction and from the same end of the coil, substantially as described.

parts.

I may employ several continuous conductors, A, and I may arrange the helices B and O in multiple arc in said conductor.

To illustrate, Fig. 1 represents the conductor with a set of helices, B B B in multiple arc, 25 and a second set of'helices, O 0'0 also in multiple arc, the two sets being joined by the part D. I arrange these helices to form the coilin which, for example, a current is to beinduced, as represented in Fig. 2. Here the helices B 30 B 3 alternate with the helices O O G. The connecting-wire D is outside of the coil, and the current passes through in the direction of the arrows. This is obviously a coil of low re sistance, and is therefore especially suited to 5 all cases where a low-resistance coil is advantageous.

In Fig. 3 I represent my invention embodied in an induction-coil such as is used, for example, in connection with a telephonetrans Xl itnesscsz JOHN BEIGE, PARK BENJAMIN.
