INSULATED SUPPORT FOR ELECTRICAL CON DUCTORS.

Application filed May 18, 1918. Serial No. 235,334.

To all whom it may concern:

Be it known that we, LOUIS SrnINBEncER and GUY HILL, citizens of the United States, and residents, respectively, of the borough of Brooklyn, county of Kings, State of New York, have jointly invented certaln new and useful Improvements in lnsulated Supports for Electrical Conductors, of which the following is a specification.

Our invention relates particularly to 1nsulated inductance coils for use with surrents of high frequency and high potential, and thus especially adapted for use in radio apparatus.

One of the objects of our lnvention 1s to provide a mounting of insulating material for the inductance coil, said coil being molded to the insulating body in such fashion as .to be exposed upon both sides thereof.

Another object is to provide an inductance coil with an internal insulating support molded to the coil throughout the central. horizontal plane thereof.

Another object is to combine a mounting of insulating material with an inductance coil in such fashion as to secure the coil rigidly to the insulating material at a single molding operation, the 0011 being exposed upon hoth sides of the support of msulating material.

Another object of our invention is to provide a simple efiicient inductance 0011 for use-for high frequency, high tension currents, which is easy and inexpensive to manufacture, and which has high mechanical strength and high electrical efliciency.

Other objects will appear from the specification and claims:

Referring to the drawings in which s11n1- lar reference characters indicate like parts in the several views;

Fig. 1 is a plan view of a support of insulating material and an inductance coil secured thereto embodying our invention.

Fig, 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary View of a strip of an inductance coil showing the preferred construction affording means for securing the coil to the insulating material.

Our invention herein shown and described may. be applied to any convenient form of support and we have shown as illustrative of the support a disc or plate S of solid. insulating material.

In the embodiment of our invention the spiral coil C is preferably constructed from a metal strip, the width of which is sufiicient to extend out upon both sides of the central plate or support of insulatinug material as at a and b when the said plate or support is molded to the central portion of the strip, as clearly shown in Fig. 2.

Our invention contemplates securing the plate of insulating material to the central portion of the coil, at a single molding operation, holes 0 being provided along the central line of the strip forming the coil so that the coil C is securely anchored to the plate S of insulating material by the said material passing through the holes during the process of manufacture.

As shown in Fig. 1 h are holes for securing means to, hold the plate in fixed relation to the operating parts.

The said metal strip is molded to the plate of insulating material at one operation and it will be seen that it is simple in construction, easy and inexpensive to manufacture, and of high electrical and mechanical efiimoney.

The material used in the construction of the supporting plate may be of any suitable insulating material, but we prefer to use for that purpose the insulating material which is known in the art as electrose. The strip from which the inductance coil is formed is made of metal or any suitable kind of metallic alloy.

As changes of construction could be made within the scope of our invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having now described our invention what we claim as new and desire to secure by Letters Patent is:

I. In a device of the kind. described, a support of insulating material, a metal coil molded at its center to the said support, the edges of the said coil being exposed upon each side of the support.

2. In a device of the kind described, an integral support of insulating material molded to the central portion of an integral metallic coil, the edges of the coil being exposed on each side of the support.

In a device of the kind described, a support of insulating material, a metal coil consisting of a strip molded to the support, the support lying in a median plane of the coil, the coil extending from the support on each side thereof.

4. In a device oi the kind described, a support of insulating material, a metal coil con sisting of a strip molded to the support, the support lying in a median plane of the coil, the coil extending from the support on each side thereof, means on the coil to secure the same rigidly to the support of insulating material.

5. In a device of the kind described, a sheet support of solid insulating material, a spiral inductance coil intimately secured at its center to the said sheet support, the edges of the said coil being exposed upon each side of the said solid sheet support.

6. In a device of the kind described, a sup port consisting of a sheet of insulating material and a metal coil consisting of a strip secured to said sheet of insulating material, said sheet lying in plane intermediate the planes of the exposed edges of the coil.

7 In a device oi the kind described, an integral support oi insulating material and a metal coil consis of a strip intimately secured to the integral support, said support i ,esasoo 'lying in a plane midway of the planes of the exposed edges of the coil.

8. In a device of the kind described, a supporting sheet of insulating material, a metal coil consisting of a strip rigidly secured to the said, supporting sheet, in a plane median of the coil edges, the said coilprojecting from each face of the insulating sheet.

9. A coil structure comprising a supportin web member consisting of a sheetof in su ating material and a convolution of con ducting material carried thereby at right angles to the plane of the web member and projecting beyond its opposed faces.

10. A coil structure comprising a support ing web member consisting of a sheet of insulating'material and a convolution of conducting material molded thereto atright angles to the plane of the web member and projecting beyond its opposed faces.

In witness whereof we have hereunto set our hands at the borough of Manhattan, city and State of New York, this eighth day of May, 1918..
