FREDERICK' M; MAUR, on rRizzsco'rr,` ARIZCNHV Y l VELECTRIC 'svvi'ilcml A-ppiication ined my 29, 1926. `seniaino. li2'`5 ,7311" ."f l' This invention relates to electric switches, and` liasfor one of its objects-to provide a novel, simple andrhighlyeiiicient device of this character through the mediumlof which,
one series of a plurality of seriesof tuning instruments, the tuninginstr'uments-L of` the respective series being y' offdiiferent inductance, may besimultaneously connectedV in the circuit of a radioureceiving apparatus'f provision of a v` switch of this character through -thefmedium-Lof which one series of the tuning instruments and a fixed condenserfmay be Vconnected in the'circuit ofia radio 5, receiving apparatus'` i W'ith the foregoing andv other objects view, Vthe nature of which will be-come appart-i entfas the description proceeds, the invention i consists of the novel construct-ion, Vcombina'- 2O tion and arrangement, of vparts'hereinafter,

...The switchcomprises a base l'which may be made of any suitableinsulating material formation. Thebasclfis hollow and is provided with brackets 2" to 'permit'git V toi Vbe i. readily secured in applied position.. Bars 3 are secured to :and extend.acrossthe'ends' ends of the'shafts 5 and are forked, and

its .longitudinaledges. VAdjacent' the other longitudinal edge` thereof,- the carrier v'l' provided relatively spaced lugs or projections'Q which extend'laterally from its opposite sides, The lugs 9 at one side lof the carrier 7rv are alined with those at the other side vof the carrier, and suchparts provide1 guide waysor grooves-10; The-car` rier 7 'is provided withf bores11 which .exif
tend transversely. therethrough y and are lo;
cated in alinement with theguide ways or` grooves 10.' i l A Series of contactblocks12 aresec'ured to the base 1 :by .meansfof-bolts 13 to whichI are 'alsof secured wirefretaining clips 14,
Each series Ioffcontact,blocksf12' extend lon` gitudinally ofthe base4 1 and the respective series -of contact blocks lare y preferably equallyV spaced. The contactblocks `12 are locatedl within, rand, the clips 14 externally of the base 1.v 1Rods.15,fare slidably `mounted tofcertain adjacent.endsthereof,arewirere-- erablyof yinverted lUfform. The-'side mein-V due thereto the ,ro,ds 15` and the parts carried blocks 12 so as :to establisha goodelectri-v cal Contact between these lpartsQand this is4 l accomplishedY by springs 18 mounted on the cent edgevof thelcarrien'.,
1n practice, a set of two tuning instruments of the sameor different inductance, are connected to each series of the Contact blocks 12, the ciicuit wires are connected to the brushes 17, and a variable condenser is '1 connected to the Contact strips 21 and 22. By turning the carrier 7 through the me-.
i Without switching .the condenser 278 in circuit with the variable condenser. By moving the carrierk 7 so as to position the blades 23 and 24 in contact with the strips 21 and 2 2, the condenser 28y will be switched inv circuit with the variable condenser, and at the same.
time one of the setsoil timing instruments will be switched into the circuits, this being brought about by reason of the fact that, when the blades 23 and 24 are in contact i. with the strips 21 and 22, the brushes 17 are in contact with the adjacent series of blocks 12.y y y twocircuits to be timed to any one o fhfour dijterent wave bands. vFor each additional circuit that isy to be controlled by means of tlie'switch, two additional contacts are added Y to the carrier 7 and an additional series of Contact blocks is .added to the base l. It desired, theA base linay be made of cylindrical formation in orderA tol adapt it to carry the maximum number of series Aof contact blocks. The switch may be used for purposes other than that set forth, as will be readily apparent to those skilledv in the art.
Where a .variable condenser is desired in place of the fixed condenser 28 such condenser. is removed from the clips 26 and 27 and ileXible leads connected to a variable condenser fastened to the panel are soldered to the clips. In order4 to provide each waveband witha condenser of suitable capacity, a set of strips like 21 and 224 are pro'videdfor each waveband and the leads which run from the tuning condenser to 21l and` 22 are changed to the clips on. the switch blades, where they are soldered, and the leads y from all the other variable condensers are attached to the wave bands to which they'belong through.
rThe switch structure shown will enable` strips such as 21 and 22 which are placed on the Vedge of the base in the saine position relative to their own tuning instruments as 21 and 22 are placed relative to theirs. This arrangement makes it possible for one radio set to contain permanent coils and condensers necessary to cover all wave bands.
It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions. Furthermore the .saidA drawing is illustrative of a preferred construction, itpbeing my expectation that various changes and modifications may be made without departing from the spirit and scope of my invention. v
What is claimed is:
1. A switch comprising a base, contacts carried by the base, blades, `means movably supporting the blades from the base, means insulating the blades, and an instrumentv support-ing clips carried by the blades. y i
2. Aswitch comprising abase, contacts carried by the base, blades, meansmovably supporting the blades on'tlie base, means insulating the blades,.and a condenser carried by and electrically connected to the blades. Y
3. A switch comprising` a base, a plurality of relatively spaced series of contact Vblocks secured to the base, a carrier, brushes supported by the carrier, means for mounting the carrier to permit the rbrushes to be moved into contact with any series of blocl{s,'con tact strips ycarried by the base, blades insulated ,from each other and supported by the carrier for cooperation with the contact strips, anda condensercarried by and elec# trically connected to the blades.
4L. A switch comprisinga base, a series of contact blocks secured to the base, a carrier, brushes supported by the carrier, contact strips secured to the base, blades insulated from each other and supp'ortedby the carrier, means for Amounting the carrier to permit the brushes and blades to be siinultaneously moved into contact with said blocksv and strips, and a condenser carriedv by and electrically connected to the blades.
5. A switch comprisingL a base, a rotatably supported carrier, contact blocks secured to'. the base, ,rods'extending through and slidably supported by the: carrier, brushes secured `to corresponding ends of the rods and contacting withthe carrierl to prevent the rotation of the rods vwith respect to the carrier, clips carried by the other ends ot' the rods, and springs urging the brushes inthe direction of the Contact blocks.
1n testimony whereof 1 aiiix my signature.
