Specification of letters Patent.

Patented Nov. 29, 1921.

Application filed July 23, 1920. Serial No. 398,521.

To all? whom it may concern.

Be it-known that I, ROBERT F. GowEN, a citizen of the United States, residing at New'Y'ork, county of WVestchester, and State of New York, have made a certain new and useful Invention in Coil-Mountings, of which the following is a specification.

This invention relates to coil mounts, and is especially adapted for use in connection with inductance coils such as are commonly employed in the radio art. v

The object of the invention is to provide a a coil mount which is simple in structure,

eilicient for its purpose, and economical of manufacture.

A further object of the invention is to provide a coil mount which is specially adapted for use in connection with the honeycomb and duo lateral types or" coils now in common use in the radio industry.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth as shown by the accompanying drawing and finally pointed out in the appended claims. Referring to the drawing,

Figure l is a view in side elevationof a coil mounting embodying my invention.

Fig. 2 is a View in perspective of the same.

The same partis designated by the same reference numeral Wherever it occurs throughout the several views.

In my copending application, Serial No. 287,397, filed April 4, 1919, for self supporting inductance coils, I have shown and described what has become known in the radio art as the honeycomb type of inductance coil, and in one modification thereof as the duo lateral type of inductance coil; also in in co-pending applicatioii, Serial No. 318,63l, fi ed August 20, 1919, for inductance coil mounting, I have shown arrangements of support for use of these coils as inductance 0011s in tlie radio art where the coils are used for loose coupling of the respective ject matter of my present application asis illustrated -in the drawing forming part hereof wherein the coil 1 is circular in shape with a circular opening therethi-ough. In the form shown the coil is formed of a single wire wound upon a base 2 of nonconducting material such as cardboard or the like. The wire is wound upon the base at a constant pitch. When the opposite edge of the coil is reached the direction of the wire is reversed, but the pitch remains the same, so that this layer of the wire runs in an opposite direction, but at the same pitch. The layers are thus built up one upon the other until the required height is reached according to the specifications of the coil employed as to inductance therein,

etc, and the unit thus constructed is coated in the usual nianner with a substance which binds the coil thus built up into a rigid unit such as a self-supporting coil, with the ends 3 and 4 of the wire extending therefrom for the purpose of being connected to the terminals, which will be more fully hereinafter described. While I have shown and described the coil as of the honeycomb or inductance or duo lateral type, I do not desire to be limited or restricted thereto as it is obvious that the mounting of in invention may be equally well applied to any form of circular coil. If. desired, and as shown, in addition to the coating which acts toward keeping the coil in a selfsupporting unit a tape 5 may be wound around the coil, and preferably at the point where the ends thereof protrude therefrom to thereby retain the ends of the wire in the proper position relative to the coil. I provide a block of insulating material of any suitable shape or size indicated at 6 in which are located to extend therethrough a plug 7 and a jack 8. The plug and jack method of forming electrical contact is the method now most generally in use, and though therefore I have illustrated this type of electrical circuit connection I do not desire to be limited or restricted in this respect. The ends 3 and 4 of the wire are suitably connected, for example, soldered, to the ends of the plug and jack: 7 and 8 in the usual well known manner. The opposite sides of the block memher 6 have holes therein adapted to register with threaded horings through the plug and jack respectively. A'strap 10 is then block.

fastened to th opposite sides of the block 6,

and secured thereto by means of a metal plate 11, held by means of screws inserted through the plate; and extending in the holes in the block, and the plug and jack respectively, to thereby clamp the free ends of the strap against the respective top and bottom surfaces of the block. From the foregoing it will be seen that I have provided an exceedingly simple and efficient mounting for a-coil of the circular type, the "strap 11 holding the coil rigid relative to the block 6 with no strain imposed upon the ends 3 and 4 of the wire and enabling in a coil of this type a handy convenient unit adapted to be plugged into or otherwise electrically connected to the terminals of a circuit in which the coil is to be included. Where a honeycomb type of coil is employed, or in fact in any instances where it is desired to utilize the surrounding air for affecting the capacity-of the coil, the strap 11 may be provided with a" number of perforations or orifices therethrough throughout its length,

- Many modifications and changes in detail will readily occur to those skilled in the art without departing from the spirit and scope of my invention as defined in the claims.

Therefore what I claim as new and useful and of my own invention and desire to secure by Letters Patent is,-
