lNDUCTlON-COIL.

SPECIFICATION forming part of Letters Patent No. 349,617,61atecl September 21, 1886.

Application tiled February 10, 1886. Serial No. 191,106.

To (LZZ whom, it may concern:

3e it known that I, \VILLIAM STANLEY, Jr., a citizen of the United States, residing in Great Barrington, in the county of Berkshire and 5 State ol' Massau-husetts, have invented certain new and uselul Improvements in Induction- Coils, of which the following is a specification. My invention relates to the class of apparat us employed for converting electric energy from currents of a given potential to currents of a different potential or different quantity.

In the conversion of electrical energy from currents of a lower to a higher potential, and vice versa. by means of induction-coils, it is [5 desirable that the quantity of iron acted. upon by the currents in the primary circuit, and in turn reacting upon the coils in the secondary circuit, should be as great as possible, andthat the iron itself should be divided into thin lamime or plates, rather than united in a solid mass, and it is also desirable that the parts be so organized as to render the construction of the coil as simple as possible.

The object ot' the. invention is, theret'ore, to

23 provide a form of inductioircoil in which the magnetizable portion is formed of thin plates of softiron adapted to support the primary and secondary conductors in such mannerthat they shall be as nearly as possible surrounded by magnetic material, and shall be so located that the currents traversing the primary shall be expended to the best advantage in magnet izing the iron, and thatthe magnetization and demagnetization of the iron shall be utilized to the best advantage in establishing induced currents in the seeondaryeoils.

The invention consists in winding the primary and secondary conductors upon a suitable form, which may with advantage be 0c .10 tagonal, and mounting upon the coil or core of wires thus formed by the primary and secondary conductors annular disks or rings of magnetic material. These disks are applied by being formed with central openings of such size as to receive the wire, and they are cut; open upon one side. By springing the two ends thus formed laterally they are slipped over the core of Wire, and thus caused to surround the conductors.

In another application of even date here with, Serial. No. 191,405, there is described an (No model.)

inductorium resembling in some ot' its features that describml and claimed herein.

in the accompanying drawings, Figure l is a plan view of an induction-coil constructed upon this n-inciple. and Fig. 2 is a cross-see tion ot'a portion of the same.

Referring to the figures, a and. a represent the terminals of the primary ('Olltllltfl'm' A, and b and I) the terminals of the secondary conductor B. These conductors are wound upon a suitable torming block into an annulus, which may be of circular. or, as shown in the drawings. of an octagonal form. The ends or the conductors are secured to suitable binding-posts. The conductors having been thus termed, the iron to be acted upon by the primary conductor. and in turn to act upon the secondary coils, is placed in position. It con sists of a series of disks, 0 c, which are separately formed. Each disk has an opening through the center. as shown at d, ot'such size as to admit the core of wire, and a slot or opening (1, is cut from. the center to the periphery. By springing the ends 6 and e aside or in opposite directions the disks may be placed,one at a time,u n)n the coils. They are preferably separated from each other by non magnetic materiahforthe purpose ofrendering the coil capable of more rapid magnetization and demagnctization.

I claim as my invention 1. The combination, substantiallyas hereinbet'ore set i'ortli,with the primary and secondary conductors of an induction-coil wound to form an annulus, of a series 01' slotted plates of soft iron, through \vhichthe conductors extend.

2. The combination, substantially as hereinbefore set forth, of a series of magneticallyseparated disks or plates of sot'tiron, each hav ing a radial slot, and primary and secondary conductors extending axially through the same, substantially as described.

In. testimony whereof I have hereunto subscribed my name this 28th day of January, A. D. 1886.

\VILLIAM STANLEY, JR.
