ings; and I do hereby declare the following are realized in the preferre to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention has to do with mountings for inductance coils, and relates, more particularly, to mountings for coils of the honeycomb and similar types. These coils areintended more especially for use in radio apparatus, and are made in a large variety of sizes ranging from a few turns up to several hundred turns. Heretofore the mounting of substantially different size coils has necessitated the use of different size straps for attaching the coils to the mounting block. The inherent disadvantage arising from this necessity will be apparent.
One of the objects of the invention, therefore, is the provision of a, device adapted for mounting coils of widely different sizes without involving any alteration orsub stitution' ofparts in order to accommodate different size coils.
Further objects of the invention are simplicity of design, convenience in operation, and economy in manufacture all of which embodiment hereinafter described in detail. 7
The structure constituting the preferred embodiment of the invention comprises ,a block preferably molded of insulatin material to which are secured a plug an jack or other suitable conductive connecting means whereby the block can be uickly plugged in or otherwise connected bot electrica ly and mechanically to an appropriate .fixed su portin member and likewise quickly etach therefrom. A U-shaped strap of suitable design to receive the coil to be mounted and having end portions of sufficient length to accommodate coils of the greatest number of turns which are likely to be used is provided, being referred to hereinafter as a tie member inasmuch as its function is to tie the coil to the block. Each of the two end portions of the U-shaped tie COIL IOUN'IING.

member has a plurality of apertures which are adapted to be engaged by a cross member in the form of a rod which is tapped "after each endportion of the U-shaped tie member has two apertures of the same size with either of which the cross member may be engaged, depending uponthe size of the coil to be attached to themounting. For

For a detailed description of the preferred embodiment of the invention reference will now be made to the accompanying drawing, in which Fig. 1 is a sectional view through an inductance coil mounting and a fixed supporting member therefor;
ig. 2 is a sectional'view along the line 2-2 of Fig. 1; 4
Fig. 3 is a view, partly in cross section, along the .line 3-3 of Fig.1; V
Fig. 4 is an'eleyational view of the mountin including a'portion of a coil having a re atively large number of turns;
' ing end pieces 5. In Fig the cross member.
In Fig. 1 an inductance coil 1 of the honeycomb or duolateral type is shown attached to the mounting. This coil is of about medium size. The mounting comprises a block 2 of molded insulating material such as hard rubber or bakelite having a pair of integral lugs 2 against which the coil bears.
A U-shaped metal part 3 which may be appropriately referred to, in view of its function as a-tie member, firmly holds the coil against the lugs 2. As shown in Figs. of the tie member 3 with which the cross mem er 4 is adapted to engage by means of the grooved insulats. 1 and 4 the cross member 4 is engaged with the two apertures 3. These latter apertures are utilized for mounting the larger size coils, While the apertures 5 are utilized for mounting smaller coils,
as indicated in Fig. 5, wherein is shown a coil 6 having but a few turns. A flat head machine screw 7 passes through an aperture in the block 2 and engages the tapped hole 4 in the cross member 4. The screw 7 is referred to as a clamping screw in view of the fact that it operates. to apply tension to the tie member 3 through the medium of the cross member 4 for clamping the coil against lugs 2'. The clamping screw 7 is preferably of such length that the largest standard size coil may be mounted. The facility with which coils may be mounted and dismounted on this device will be readily apparent from a consideration of the drawing, it being seen that the only operation necessary in removing the coil from the block is the removal of the screw 7. Thisreleases the tie member 3 and cross member 4, which two members are readily separable. The block 2 is provided with a metal plug member 8 and a metal jack member 9. These two members are referably molded into the block 2 and are t ereby held very securely. The plug member 8 has an external rtion 8 which is preferably provided witi two diametrical sawcuts arranged at right angles. The end of the portion 8 is preferably of slightly larger diameter than the remaining part'. By reason of this provision the plug will readily enage with a corresponding jack 10 in the ed supporting block even though the center to center distance between the plug 8 and jack 9 may be somewhat inaccurate. This first, to the fact end of the plug bears against the and second, to the resulting from the sawis; due larged wall of the jack, iencyil of the plug resilthat only the an I cuts. The plug will therefore bend upon being inserted sufiiciently to compensate for any reasonable commercial inaccuracy in the spacing. It will be noted that the jack 10 in the fixed su portin block 11 corresponds functionall with t e jack 9 in block 2, and likewise the plug 12, which is molded into the block 11, corresponds functionally with the plug 8 in the block 2. The two plugs 8 and 12 may therefore be substantially identical, and likewise the jacks 9 and 10. The plu 8 and jack 9 are each provided with a llister head screw 13 by means of which the wire terminals of the coil are connected respectively to the plug 8 and jack 9. The xed block 11 is secured to a plate 14 by means of the round head screws 15, and the plate 14 may in turn be attached to a suitable panel 16 by means of screws17.
It will be noted that the block 2is formed with a suitable slot 2, in which the cross member 4 may slide forward and back for the purpose of accommodating different size coils. I
I claim:
1. The combination with an annular wire coil having wire terminals, electrical terminals therein connected to said wire terminals, a U-shaped tie member extending through the opening in said coil for of a block having securing said coil to said block, a cross memv ber engaging the two end portions of said U-shaped tie member, and a clamping screw engaging said cross member, said clamping 11c through the medium of said a ertures, said cross memher being engagea 1e with difi'erent onesof said apertures to accommodate difierent size screw engaging said coils, and a clamping cross member, said clamping screw bein operable to efiect variable tension on sai tie member. 1
