Be i-tknown that IiHneoGEizNsnncL-a citizen-,iofwtlie United-Mtates, residing. at New York-,inthe coun-typt New 'York 'and State off New: York, 5 have g invented, certain new. and useful: I Improvements A- ,a ,i Coil Mounting/auf which', the. ifollofwing is1 apspecif'ClOI.: 5...', ma. ij;;`ff., ,fi-5 ii This invention relates,=to. coils fon ,radio l0 work, and I the: primary objects, of...th e ,.inven; tion are, first todprovidernoveli means,V for .mounting the. coils proper in place-andi sec.- ond novelfmeansfiforaassociating the coils 'properkwith: the base,;wl1ereby( coilsfcan be readily put in orpulled ;out ofsthe. cir

Another primefobject of the invention is to :provide-a; coil l embodying, ar base provided with agplurlality. of novelly arranged sockets, so disas; taper-mit; .the swinging thereof, and novelzelongatedfhandles. or blades rfuponr whichthe@y coilsl propernpref- Aerablvy-of'y the spideriwcblty'pe are mounted,

Referring toy the drawings in detail,

A further:V object-fof lthe inventionl isyto handlesor blades Cv and the novel coils propt The base B is constructed from insulatlng'material and includes a baseplgate 10 having. depending base; flanges -11' formed on the marginal edgesthereof, which foi-rn a support Afor the said base plate 10y and permit the spacing thereof from the support upon which it may be placed.

Disposed upon tliefupper surface off the base plate-10 at equi-distant spaced points are pairs of-supporting.

brackets

12, 13 and y 14.l These pairs of .brackets 12, 13.and.14

are constructed of electric conducting inaterial and the-brackets of each pair aredisposed in longitudinal alignment, while the pairs of brackets'arc dispose-din transverse alignment, and each bracket is of substantial L-shape when viewed in elevationand includes the attaching portion 1,5 andthe f upstanding arm 16.l

Figure-8 is av detail horizontal section .taken `rongtlie line 8'-8 of Figure 6 illus- 17 offthe endpairs of retainingbrackets 12 and-l4=`-V 'i T he arms 16 of the retaining brackets support the sockets 18 for a purpose, which will le hereinafter more fully described.

The sockets 18 carried by the various pairs of

brackets

12, 13 and 14 are of the same construction but it is preferred to have the sockets carried by the endportions of thc brackets mounted for rocking movement, while the socket carried by thevcentral Vpair of brackets 13 is preferably rigidly secured to the said central pair of brackets."

Each of these sockets however, 'includea spacing block of insulation 2() and'upstanding 'resilient contact arms '21. "These-,arms 21V are substantially U-shaped in'cross sec tion and forni `,guides 'for Vthe removable portions or handles() of the'device.

As shown the lower portions of thesockets arepoll'set slightly and' connected,`- 'vvithtlie end 'portions ofthe spacing block of insula- Avtion 2O 'and these connecting portions'of vthe sockets are adapted to be inintimate con tact with the arms 1,6 of the variousl brackets at all times. Suitable retaining screws yor the like 22 extend through the arms 16 of the various brackets through the sockets 21 and into the spacing blocks 20: Byjthis construction it is obvious fthat" saidsockets can freely' swing on the brackets." Thev screws which support the c'entral'fsocketf'aije relatively tight, so as to prevent'the'swinging'of the said block and l`socket carried thereby.

elongated thin flexible body 25 formed of insulating material and if so desired "the said bodies can gradually taper toward their free ends.

In the drawings I have only illustrated one handle and one coil connected with the base but it is to be understood of course that each lof the sockets 18 can have one ot the handles connected therewith.

Disposed intermediate the ends of the handle C is arranged a plug 30 of insulating material having an annular flange 31 formed at one end thereof. This plug is adapted to be secured vto the handle by a suitable movable screw or the like 32 and extends through the handle and through the axial center of the said plug.

The coil D carried by the handle is preferably of the spider web typel or flat inductance type constructed in accordance with 'my pendingv application iiled'Feb. 9, 1923, Serial Number 618,075. The plug 3() extends through the axial center of the coil D and the reinforcing pins 33 of the coil are adapted to engage said plug and thus the plug tends to hold the reinforcing pins in place. The annular flange 31 engages the outer face of the coil and the inner face lwhich are of like construction.

The terminals 34 and 35 of the coil are connected to contacts 36 and 87 As shown each of the contacts include a metal plate bent varound theopposite edges of the handle C at the lower end thereof and these plates are heldon the handleby' means of suitable rivets orthe like'l 38fwvhich also form'means for Eholding the'terminals 34- and "-35 in engagement withfisaid plates.

4. In a radio coil unit, a handle formed of insulating material, a coil carried by said handle, contact plates secured to the lower end of said handle at the opposite sides thereof and connected With the terminals of the coil, and curved portions formed on said plates extending around the opposite edges of said handle.

5. In a radio coil unit for the purpose specified, a handle formed of insulating material, a flat inductance coil including abody and a plurality of reinforcing pins extending through the body formed of insulating material and terminating at the inner periphery of the coil, a plug of insulating material fitted in said coil engaging the inner ends of said pins, an annular flange formed on the outer face of the plug engaging the outer face of the coil, the inner face of the plug being fitted against said handle, and a retaining member extending through said handle and through the axial center of said plug for retaining the plug in firm contact with the handle.
