INDUCTION-COIL.
SPECIFICATION forming part of Letters Patent No. 227,546, dated May 11, 1880.
Application filed January 12, 1880. I
To all whom it may concern:
Be it known that, I, FRANK A. KLEImvI, of the city, county, and State of New York, have invented a new and useful Improvement in InductionOoils, of which the following is a Specification.
In the drawings, Figure 1. is a plan view of my induction-coil partially broken open. Fig. 2 is a partial longitudinal section.
Similar letters of reference indicate corresponding parts.
In induction-coils as heretofore usually made the primary coils are first wound on the core to the extent required, and the secondary coils then wound on the primary, so that only the outer layers of the primary and inner layers of the secondary are in intimate connection,
and but a small portion of the wire is utilized.
As an improvement upon this old method of winding, it has been proposed to wind first a layer of primary and then a layer of secondary.
My invention relates to an improvement in this line; and it consists in combining insulat- 2 5 ing material and two or more contact layers of primary with two alternating layers of primary and secondary, as hereinafter described, whereby I produce a stronger or superior effect.
B is the induction-coil. The primary and secondary wires g z are first wound together in two or more layers, as clearly shown at Fig. 2. These are then covered by paper or other insulatingmaterial, f,- thcn the secondary 'i is wound in two or more layers, and so on, so
that the primary lies next to the core and the secondary on the outside, and the relative size and arrangement of the two wires is such that the secondary is always nearer to the field of 0 the primary influence, and at the same time induces to the proper amount of resistance in the secondary.
This mode of winding and insulating enables me to keep as close to the primary as possible, and yet get a much stronger induc- 5 tion than is practicable by any other method known to me. The efl'ect is as two or three to A one in favor of my coil.
In coils formed by regularly alternating series of primary and secondary the primary is used for mainline purposes, and the secondary for local purposes, which is the reverse of the use forwhich the respective wires in my improved coil are adapted and employed. My coil is especially valuable in telephone- ,5 5 transmitters, where economy of space and weight is an advantage.
I am aware 0t Letters Patent to T. P. Shaftner, No. 60,432, granted December 11, 1866,
- which shows a novel means of winding to secure polarity; but this is not the object of my invention, the gist of which rests in the idea of so winding as to insure about twelve times more secondary than primary wire in length, and hence I Secure a proper resistance to overcome the resistance in the main line.
What I claim is The improved induction-coil hereinbet'ore described, the same consisting of two alternating series of primary wire, g, and secondary i, an insulating material, f, and two contact layers of secondary, i, which are wound in contact upon said insulating material, as shown and described, for the purpose specified.
