LOUTS STEINBERGER AND GUY HILL, OF BROOKLYN, NEVJ YQRK.

INSULATED SUPPORT FOR ELECTRICAL CONDUCTORG.

To all whom, it may (0%."0771 Be it known that we, Louis Srnnvnnncnn and GUY HILL, citizens of the United States, and residents, respectively, of the borough of Brooklyn, county of Kings, city and.

State of New York, have jointly invented.

certain new and useful Improvements in Insulated Supports for Electrical Conductors, of which the following is a specification.

Our invention relates particularly to in sulated supports for mounting inductance coils in radio apparatus, said supports or mountings being constructed entirely of insulating material.

One of the objects of our invention is to construct the mount for the conductor forming the coil entirely of insulating material, no metal being utilized in the construction of the mount or support other than the metal of the coil itself.

Another object is to provide a construction by means of which a mount may be formed and the coil embedded in and se cured to the mount at a single molding operation.

Another object is to provide a series of separated bosses or projections of insulating material so situated and arranged with respect to the disk or sheet of insulating material that the coil may be properly mounted. and anchored to said projections.

rinother object is to so construct the mounting that the coil may be conveniently and economically put in place and securely mounted in the insulating material during a single molding operation.

Other objects will appear from the hc1'cinat'ter specification and claims.

Referring to the drawings, in which similar characters indicate the same parts in the several views:

Figure l is a plan view of an embodiment of our inventio Fig. 2 is a section line 2-2 of Fig. 1.

Fig. 3 is a section partly broken away on line 3-3 of Fig. 1.

I 4 is a perspective view of a broken section of a form of electrical conductor.

- This application is a division of our prior partly broken away on application No. 202,1l3, filed November 15,

Referring to the figures,- the insulated support 10 is generally in theiorm of a plate, slab or d sk.

specification of Letters Patent.

Patented June 1., 1920. Divided and this application filed May Serial No. 235,836.

The disk or plate 10 of insulating material forming the support is provided with a series otintegral studs or projections 12 extending in series of radial lines from the center to the periphery of the disk. Any suitable number of lines of projections may be provided but we have illustrated four lines of these projections situated about 90' degrees apart (see Fig. 1)

lVe also provide between the radial lines of projections a series of perforations 14: which also extend substantially in radial lines from the center to the periphery of the disk, and are so situated with respect to the coil 13 that air is admitted for cooling the structure and thus ample-ventilation is provided. The apertures also reduce the weight of the disk or sheet of insulating material and thereby reduce the cost of construction.

The coil 13, consisting of a strip of metal or alloy, is molded into the studs or projea tions 12 and held or anchored therein by the plastic insulating material passing through the perforations 15 in the edge of the coil 13 as clearly shown' in Fig. 2.

In constructing a mount such as shown and described in which the disk and. integral studs. both of insulating material as shown in Fig. 1, are formed, the coil is secured thereto and anchored thereto during the molding operation.

Our invention may be readily assembled and quickly constructed at a minimum cost, inasmuch as the entire structure may be formed and assembled atone molding operation.

Any suitable insulating material may be used in making the structure described, but we prefer to use that insulating material known in the art as electrose.

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

Having now described our invention what tors Patent is: Y

1. In a device of the kindxdescribed, a plate or support of insulating material, a series of insulating studs integral therewith and. projecting from a side thereof.

2. In a device of the kind described, a

'we claim as new and desire to secure by Lot-- plate or support of insulating material provided With a series of insulating studs projecting from a side thereof and integral therewith, a conducting coil molded to said studs.

3. In a device 01 the kind described, a plate or support of insulating material, a series of? integral insulating studs projecting from a side thereof, a conducting coil, one side of which is molded to each of said studs,

1. In a device of the kind described, a plate or support of insulating material, a series of insulatiln, studs projecting from a side thereof and integral therewith, a conducting coil. one edge of which is secured to said studs.

In witness whereof, we have hereunto set our hands at the borough of )lanhattan, city and State of New York, this 8th day of May, 1918.
