RADIORECQBD.

Application led April 7,

The ,objectief myfinvention isto provide la radio yrecord of .simple `and inexpensive construction, .which may .be usedby those einploying radio receivingsets for convenient'- lyy recording. .certain datain connection with radio sending ,and reception in such manner that the records will he quickly and easily accessible for reference. f

More particularly, it is my Object .t0 provide .airadio `record having a plurality :of series `of sheets arranged in superposed` relation and conveniently connected .together in a case.

Thisdevice .has ,a number of novel features v,of vc(instruct-ion .and .,arrangement, which facilitatetlie making Avof records rand .the convenentreferlenee thereto.

.lVitlrthese .and ,other `objects.in view, my invent-ion `consists in the construction, arrangement and VVcombinationof the various parts of myradio record, whereby the objects contemplated fare attained, las herein- 'after more fully Aset vforth,,pointedout in my claims, and illustrated in the j accom- .panying drawings i in which;

-Figure 1 is a perspective viewof-a radio record embodying .niy invention.

` Figure 2 is a plan view, certain parts Abeing shown in section ,and other parts being brekeneawayyoe .of die sheetsbeiiigiadjustedy yto .I a different Iposition from they position illustrated inligurel.

YFigure 3 is a.A plan view of .the yrecord showingfanother. of VAthe `sheets ,adjuste ;l v to a ,ditl'erent 4position from the position illustrated in ililigure 1; and: l Eigur-e 4F is ,a detail, sectional view taken onatheline `of Figurel 2.

I My radio record includesA a Series of senil` circular sheets, .the series being indicated generally bythe reference character A and the-separate sheets vby the referencek nuigneial 10. These sheets are. superposedon each other, l-anda t Vthe central part oftheir sul -stan-tially straight ,edges are provided `'with the projections lOYL for a pivot p :iiir'the like .11, by ywinch they are .connectedto- ...gether-` in -superposed relation.

'Resting onthe seriesAis a second `series 'Bvoffsheets 12v ofthe saine shape but of Aslightly .shorter radius. The sheets 12 of the series B are likewise mounted on the .pinpll x Extending circumferentially from the straightedgeof one side..O theslleets 10,

the sheets i are:` provided their outer edges iaa. serial No. 100,363.

with successive longer notches 13, 13a, 18b and so forth. `At the opposite sides, the sheets 12 are provided with radially eX- tending tongues 14a, 14", 111C and so forth, which ,are lsuccessively longer circumferentially, or have theirlower edges ,spaced from an upper edge at successively greater distances. f

Onthe sheets 10,011 the portions exposed through 'the notches 13 and Iso forth', AI mark index matter 15. Arranged inwardly from the'indexinatter v15 inradial lines on the sheets 12, l' arrange indicating matter 16, such for instance as the call letters of sending stations vand the addresses of such stations. The circumferential columns thus formed may 'be headed by the words Gall and Location' In the radial lines are left spaces 17 lfor the insertion of dial readings, and the col-V umn ,formed by such spaces may be headed by the V.wordsDial reading.

On the tongues 14a and so forth, I arrange indexing matter, such for example as the callletters ofcertain stations and radially inwardly from the indexing matter on the tongues .14a and so forth, I arrange indicating matter 18, suchfor instance as call letters', addresses of sending stations, the numerals indicating the wave meter length on which suchstations broadcast, andthe power' of the stations in watts.

rI he `circumferential columns, as thus formed, mayfbel headed, as shown inFigure 3, by the words Location, lvVVave meters, Power watts, and YCall Supported on the pivotpin 1'1 and receiving .the sheets 12 and l()v is acasing comprising a topmembei 19,'bot'tom member .2O anda connecting. wall 2l extending Vfrom one edge of the casing inwardly toward the. center on one side vof the center only, shown in'lligure 1. Thus when the sheets k10 and 12 are all in superposed position, their straight edges on one side of the rcenter lfornied by ther pivot pin ll'will snugly rest against` thel wall Av21.

ltwill-be noted that the casing portion 19 is of such radius las ,tol leave exposed the outer edges of the sheets 10 and the tongues 14a, etc., of the ,sheets 12. i

The utility of having the notches on the series of sheets A and and the tongues on the series ofsheets'Bisto enable a considerable number of sheets to be indexed without making `the index members have other. This is accomplished by placing the diiilerent kinds substantially opposite each other.

Connected with the pin ll by means or" a string or the like 22 is a pencil 23 for the convenience of the user of the record.

The portions ot the sheets l exposed below the notches 13 and so forth are provided with holes 2li, and the tongues lili and so forth are provided with similar holes 25, which will receive the ysmall end ro'lf the pencil 23 tor the convenience in manipulating the sheets.

ln the practical use oit' my improved radio record, the index matter l5 is placed, as shown. For example, ll use the letters ot the alphabet, and then radially inwardly from the appropriate index matter, l place the call letters oi the stations and the names ot such stations, coming under the index matter on the particular sheet. Then as the dial readings are ascertained, they may be placed on the proper sheet.

0n the tongues 14 and so forth ot the sheets 12 of the series B, place index inatter, such for instance as call letters, and then in the radial lines of the sheet, the address, call letters, wave length records and power records.

One advantage or a record of this kind arises from the tact that it can be completed by additions as the user may desire.

When it is desired to inspect the record, such inspection is easily made. F or instance, it the user desires to look up the station at Grand Rapids, Michigan, he refers to the index matter l5 under Gn puts the end ot the pencil in the appropriate hole 24, and rotates the sheet Ytor exposing it. In the appropriate column, he i'inds Grand Rapids and the call letters and the dial readings, it' they have been placed on the record.

Similarly it the user has the call letter ot the station, and desires to look up the data with regard to that station, he uses the point of the pencil 23, inserted into one of the holes in one of the tongues lea and so forth, tor moving one of the sheets 12 out of the pile, as illustrated in Figure 3, to make visible the data concerning location, wave meter length, and so forth.

lt will be noted that when the sheets are superposed in normal position, there is an imperforate portion ot a sheet below each hole, so that when the pencil is inserted into one hole for moving a sheet, it is stopped by the next sheet, so that only the desired sheet will be moved out.

lin pushing the sheets back into position,

the wall 2l serves as a stop, so that they may all be easily and conveniently moved to position in the stack superposed one above the other. It also serves as a stop or gauge which is engaged by the edges ot the sheets, ior properly holding the indexes in alignment and visible.

it will be seen that I have provided a record, which is 01"' a very simple construction, to which data may be added from time to time as may be desired, and which makes all oit the data readily available in an inexpensive compact device.

Some changes may be made in the details of the structure oit my radio record, without departing 'from the real spirit and purpose ot my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

claim as my invention:
