VthatV particular' station may be placed; the drum being capable of being rotated to'bring 10 any desiredfstationlto display position.

The general object of the present invention.

posed within the transparent` or semi-transv parent drum and withinwhichthe. lainp isv disposedV andv provide means f whereby, ,the

drum may be rotated relative to the reflector '25 to carry the data columnson the Vdrums successively in position in'front ofthe reflector.v

A further object 'is to providel a device of this V character which isl so constructed that it may be easily disassembled 7 or reassembled,

a(" fvvhich will permit the `removal and replacement of the vsheet having thereon the station data if desired and Vwhich is particularly handy, convenient and'comp'act. i. i. V.Other objects will appear in the ycourse of 5 thefollowing description. n Y

Y Mounted upon -the lower cross bar 13'of the fixed frame is arelectorj24 which carries within it theelectric light' bulb 24a. The re-Y flector `may beY angular in cross section or may be'curved als-desired and'it is to be un-V e derstood thaty v'the'larnpv bulb 24; might be disposed in any desired positionV within Vthis reflector and that the lamp "may be of any suitable'fcharacter." VThe lamp maybe inl-the form of a small 'globular bulb or an elongated bulb 'extending longitudinally fof thev re- "90 flector. Wires 25 lead through the'tub'ular shaft`12 to the'soclxetfor the lamp and' con- `nect therewithiny any` usual-V or` suitable manner. 4

i VThe .frameformedf ofethejbars 19 de- 95 signed tov lsupport a tr'ansparentiorsemitransparent drum y26 and this drum may Vsiinply be slid'A down overV the "bars 1,9.

Adapted Lto' be disposed exteriorly ofthe 66 Vflectorsothatbyits use', not only is the light card board sheet 27 having thereon the station n'umbers,names and other pertinent matter associated therewith and opposite eachstation a blank space within which the dial` ing indicationsare to be written bythe user. Preferably, though not necessarily, there will be an outer covering of thin Celluloid,

glass or other vtransparent material disposed exteriorly of this sheet 27, this being kdesignated 28 and extei'iorly ofrthis outer covering there may be disposed aV housing 29 which -will rest upon the flange of the base 10 oi' be otherwise mounted upon the base, this hous-` in bein@r of o )a ue ymaterial but havinfa l u l 7 l vertically extending opening 30 having a width equal ,to a column on the logging sheet 27 so nthat when the logging sheet is turned to a particular position, awcoluinn of Vthe'loggingsheet will be displayed through opening 30. f

vThe drum will bepreferably covered by a cap 31. .I donot fwis'h to belimited to the useV of'this outer housingi-asthis may be .omitted if desired, though I find it preferable. Ihe housing may be closed at its up- Y:per-,end so as-to prevent any A,light from passing up through the top of the housing.` The housing, of course,will be soforined at its "upper-,end tov accommodatelthel liubq21 'and .Ktheknob 22 will, of course, be disposedex-V teriorly ofthe housing.,v n

The distance between thewires or rods V"IQ-,will be preferably equal to the width of @acolumn .on the logging sheet 2,7 so that when the logging sheet is disposed upon this frame formed by the wires 19,;the shadows ofthe wires 19 will come at the intersections of'the columns. Y v1. I

The usepfthis device will be obvious. If .it be desired to insert the dialing data-'with regard to any-particular station, the houssheet 27 and prevent its; becoming injured or blurred. Vhenever it is desired -to get a station, it is only necessaryto turn the knob 22 until. the. desired station indications are shown and then the appropriate column of initially blank spaces willcontain the indications whereby the dial of the radio may be set. 'A Y A It is `to bie particularly noted that the re- ,flector 24 constitutes a shield aswell as a retremely convenient.` 1 -While I have illustrated struction, which embodies the principle; of

, A, radio log comprising a base, afixe'dsha-ft extendingupreflected toward the exposed column of indicia on the drum, but the light is shielded from all other parts of the drum so that thus only the column desired is illuminated.

While I have heretofore referred to a drum of transparent material, or translucent ma,- terial as if this drum were formedof glass, Celluloid or like material, over kthe outer face y of which the logging sheet 27 is disposed, I

wish'it tobevunderstood that the blanks within which the station indications may be disposed may be printed upon the drum itself,

'asfor instance, upon a drum of cardboard or like material. of suiiicient translucency to per- Vmiti'the 'light from'tlie lamp 24a to shine lthrough so that the gures may be Yobserved and I wish it distinctly understood' that-I may use either an entirely transparent drum ora translucent drum,that is, a drum whichwill transmit light through yit-a'nd that bythe term transparentf7 as used in the claims,'I design to include any 'material'which will permit all or a part ,of the lightto pass rIhis vdevice is very simple, canbeL cheaply made, is attractive inV appearance,and ex- -a Particular. con

my invention,y I donot wishtoA belimited thereto as it is 'obvious that'manychanges might bewmade Vtherein-,without departing i from the spirit of the Vinvention as delinedjin of the :character described,

ward fronithe base, a frame supported said shaft', the shaft .extending upward from the upper end of the frame, a frame rotatably Vmounted upon the base, a transparent ,drum mounted upon said framefor rotation therewith and having vertical lcolumns of radioimdicia, the drumvat its ,upperV end havinga nsleeve surrounding the shaft at the A upper end of the frame, a knob carried by said sleevewhereby thec drum may be rotated, and a'reiiector disposed within ,the frame and within the drum and `heldfrom rotation,

the reflector having: its .side'edges` extended nearlyv to the drum andhaving awidth' at this point approximately equal to'one ofthe columns of indicia onthe drum, and atlamp disposed within thereflector. f l

Y Y 4. A radiolog of the character described, including a base, a rotatable drum mounted thereon, the drum being of transparent material and bearing columns of radio indicia thereon, a shield disposed Within the drum andhaving its side walls extending nearly to the inner surface of the drum and at this point spaced Vfrom each other 'a distanceequal tothe Width of a column, a lamp.
