c011. MOUNTING.

Application filed August a, 1923. Serial no. 656,495.

This invention relates to electrical coil structures, such as used for inductances or transformers, and more particularly to such structures with which a desired amount of inductance may be built up by the use of a plurality of coils of a standardized width but with graduated diameters enabling sevoral or the coils to be nested one within another. r

One object of this invention is to provide a method of mounting 'a plurality of electrical coils of the above indicated type, ota standardized maximum width, in amanner such that. any desired inductance, Within reasonable limits, may be conveniently built up to comprise a unitary structure.

A further aim of this invention is to provide an adjustable electrical coil structure, comprising a plurality of ring shaped coils of graduated diameters nested one within another.

Still another object of this invention is to provide a simple, inexpensive and efiicient clamping means for retaining one ormore ring shaped coils of the type indicated, upon a base member. The clamping or re raining means provided in accordance with this invention is such that a variable number of the coils may be used therewith, or it desired the coils may be conveniently. interchanged with other coils possessing different inductance values or current carrying capacities.

Other objects of my invention comprise the provision of an electrical coil structure of the character indicated above, which will be simple and economical to construct and which will be devoid of complicated parts and which will accordingly be simple and dependable in operation.

Other objects of my invention will appear trom the following detailed description forming a part of this specification and; from the drawings to which reference may now be had for abetter understanding of the scope and characteristic features of my invention. y H p v V In t e cc m a y n drawin sh ve illustrated an; apparatus embodying mvine vention and bywhi'ch my improved'method structure embodying I A V two C011" units clamped upon a base;v

Fig. 2 is a vertical: sectional. View: upon the line122*of 1;

I Fig. is a perspective view illustrating the base member, together with clamping straps for retaining the coil units thereon;

Fig. 6 is a perspective view of a yoke member forming a part of the clamping mechanism illustrated in Fig. 1; and,

Fig. 5 is a View similar to Fig. 1, but illustrating the use 01' my invention for mounting three coil units.

As shown in Fig. 1, the structure may comprisea basemember 10 upon which may be mounted a pluralityot ring shaped and nested coil units as at 11 and 12. A clampingmechanism 13 as illustrated in Figs. 3 and 4 may serve to retain the-coil units in position upon the base member 10.

The base member 10 is preferably formed of a suitable insulating material and is shown provided with bindingposts as at it and 1'5, to which the lead wires of the various coils as 11 and 12 maybe attached and connected to the desired external circuit.

The base member as shown is provided with a plurality of upstanding flexible metallic strap members, as at 16 and 17 between which the nested coil units may be positioned substantially in a vertical plane.

The strap members 16 and 17 may be fixed to the base member in any suitable manner. According to the structure here shown, the base member is provided with a plurality of perforations as at 18 and 19, through which the strap members may be threaded and by means of which the straps. after being bent intopositi'on, are securely held to the base member. This particular structure, it will be noted, requires the use of no additional fastening members and accordingly is very simple and inexpensive. Furthermore, when the coil units are clamped in place, all possibility of removal or displacement ofthe straps is eliminated;

The upstanding portions of the strap members may be originally formed of a suitablestandardized lengthto accommodate a l rge mb r. i; c il. U l S-.HQ Q T when the" desired number of coil units has en..- 1 s n or. aersr e c. ss m y, he flexible i pp i e" penise fl the o k. embe s r ed a" yo e P ay e n a tivui i in igthsvs m' in g lioo may comprise a" pie'ce ofiileiiible". material,

S rap m m elf i ay e easily cut,

preferably insulation formed in the shape of a channel. The edges of the channel are adapted to be engaged by the hook portions as at 20 and 21. The relation of these parts when assembled is best shown in Fig. 2.

A clamping means which may comprise a screw 23 is shown extending transversely of the channel shaped yoke member 22 and is for the purpose of causing the channel member to buckle downwardly against the interior surface of the inner nested coil. The screw 23 upon being tightened draws together the edges of the channel member, thus causing the center portion to bulge downwardly as will readily be understood.

The various nested coil units may be slightly spaced and insulated from one another, as by strips of insulation, as indicated at 24 and 25.

From the above it will be seen that a very simple form of mounting and clamping structure is provided, which upon the tightening of the clamping screw 23 will securely retain the desired number of standardized coil units upon the base member. F urthermore, if it is desired to interchange any of the various coil units with units possessing different electrical characteristics, this may be quickly done by loosening the clamping screw 23 whereupon the various parts may be disassembled.

While I have shown and described but one embodiment of my invention, it will be understood that many modifications may be made therein without departing from the spirit and scope of the appended claims and I desire that only such limitations shall be imposed upon my invention as are specifically pointed out in the claims and such as are required by the prior art.
