UNITED STATES EUGENE T. TURNEY, NEXV YORK, N. Y.
INDUCTANCE DEVICE.
Specification of Letters Patent. Patented lIEtl'. 29, 1921.
Application filed April 1, 1920. Serial No. 370,595.
To all whom it may concern:
Be it known that I, EUGENE T. TURNEY,
a citizen of the United States of America, re
siding at New York, Bronx county, New York, have invented a new and useful In ductance Device, of which the following is a specification. I
My invention relates particularly to a de vice intended to be used for so-called radio signaling.
The main object is to provide a compact inductance which is devoid, or substantially devoid, of capacity. Another object is to develop a maximum effective inductance. Another object is to construct such a device so that it can be readily inserted and used in or removed from the circuit.
Figure 1 is a front View of an inductance disk embodying the improvement of my invention, only part of the coil windings being shown.
Fig. 2 is a rear view of the same with its support.
Fig. 3 is a transverse sectional View, showing the connection of the disk to the support.
Fig. 4 is an edge view showing three ofv the disks with their supports.
Fig. 5 is an enlarged diagrammatic view showing the disposition of adjacent layers of the conductor wire.
The insulating disk 6 has a plurality of arms, such as 7 7 and 7", extending radially therefrom and with spaces, such as 8,
between them. The disk and arms may conveniently be stamped from a sheet of insulating material.
The insulated wire is wound on the radial arms of the disk back and forth alternately from one side to the other, as as 9, 10 and 1]. in Fig. 5. The next outer layer is wound on opposite sides alternately, as at 12, 13 and 14. To effect this winding it will be noted that there should be an uneven number of arms. I
The inner end of the coil is preferably fastened to an eyelet 15 secured to the disk,
and the outer end of the coil is preferably lapped aroundthe end of one of the arms and then attached to another eyelet 16, secured to the insulating disk. These eyelets thus constitute the terminals of the coil.
The support preferably consists of an insulating member 17 carrying two hooks 18 and 19 adapted to be engaged in the eyelets l5 and 16, respectively. One of these hooks is preferably carried by a spring arm 20 and has a circuit terminal and binding screw at The other hook has a suitable terminal and binding screw, as at 22. A spacing projection 23 may be provided to prevent the tact with the wire and chafing the insulation.
The device will be seen to be compact and light. It takes up but little room, may be readily shipped, stored and installed, and, more important than all else, it has substantially no capacity when constructed as shown and used in the ordinary manner that an inductance coil is used in radio work.
insulating member 17 from 'coming in con- Each layer of wire is supported on the adjacent inner layerat the points of cross ing in the space 8 between the arms- The flat arms with sharp edges hold the wire from slipping when winding. The zigzag winding keeps the adjacent sections of wire from being parallel.
I have shown herein a preferable and simple means for constituting the support for the conductorbut this is obviously susceptible of wide modification, for instance, after the conductor has been spirally wound on a support, the support may be removed and the coils may then be immersed in some suitable insulating compound, which, when hardened, affords the desired support.
One form of use in radio work is indicated in Fig. 3 where three disks are shown, 6, 6 and 6. The centralone 6 is commonly the secondary. The primary 6 is arranged close to it with a very small air space between. The tickler 6 and the primary are both mounted on brackets 24 so that they may be tilted or swung back and forth to effect the desired adjustments. On account of the verycompact fiat form of the coils they may be set close together so as to give a maximum eflectiveness. A single device as shown has been found to operate satisfactorily for wave lengths of 200 to 450 meters when shunted with a variable condenser of .0005 m. f. capacity. Two of them may be used when wave lengths of from 400 to 1500 meters are required.
I claim:
1. In an inductance device, a plurality of fiat spaced radiating arms, each of which is of substantially greater length than width, the spaces between the arms being at least as wide as the arms, and a conductor spirally interwoven with Said arms.
the arms being no greater than the width Cir of the spaces between the arms, and a conductor spirally interwoven with said arms.
3. An inductance device comprising a disk having radiating arms with a spirallywound conductor thereon, and eyelet terminals for said wire secured to said disk.
4. In an inductance device, a plurality of flat spaced radiating arms of insulating material and a conductor spirally interwoven with said arms, the width of the spaces between the arms being approximately the same as the width of the arms so that adjacent convolutions of the conductor cross each other and are supported one on the other in the spaces and the lengths of the conductor are maintained out of contact with each other exceptat the points of crossing.
An inductance device comprising a disk having radiating arms, a spirally wound conductor interwoven therewith, eyelet terminals carried by said disk, and a support therefor having two contact hooks, one of which is yielding.
6. An inductance device comprising a thin disk of insulating material, a spirally woven conductor extending radially therefrom, two terminals carried by said insulating disk, one at least of which is in the form of an eyelet.
7. An inductance device, comprising a thin disk of insulating material, a spirally woven conductor extending radially therefrom, two terminals carried by said insulat ing disk, one at least of which is in the form of an eyelet, and a support having two con tacts, one at least of which is in the form of a hook adapted to be engaged in the eyelet of said disk.
8. An inductance device, comprising an insulating disk having radiating arms, a
spirally Wound conductor carried thereby,
eyelet terminals carried by said disk, and a support having hooks engaging in said eyelet terminals.
