Like numerals refer to like parts throughout the several figures.

Referring now to the drawings, I have illustrated in the drawings one form of radio device embodying the invention. In this construction the casing or cabinet of the device is cylindrical in form and is-preferably'made in sections. As herein shown, there is an upper section I and a lower section 2. These sections are connected by a plurality of connecting members 3 which may be of any desired form of construction, but which are preferably comparatively thin metal members having at the bottom shoulders 4 which rest on the lower section 2 and at the top shoulders 5 upon which the upper section I rests. There are removable fastenin devices 6 which connect the upper section I with these connecting members, so that the upper section may be easily and quickly removed to secure access to the interior mechanism.

It will be seen that the central portion of the device is open to permit the sound to escape. I prefer to provide some means for preventing the mechanism from being observed through this open central section and also of directing the sound outwardly. I prefer to provide over this central section a plurality of projecting members I which extend outwardly from the casing and which may be of any suitable form and arranged in any suitable manner. In Figs. 1 and 7 these members are shown a being inclined outwardly, being in the form of louvers. They may extend straight out if desired. These projecting members, in addition to preventing the interior mechanism from being seen, form an ornamental construction, as is clearly shown in Fig. 1. These members may be separate or they may be stamped out of a single piece.

The dial 8 is horizontal and forms the top of the casing or cabinet. This dial may have the. usual graduations and numbers and any other data desired. In view of the fact that the dial is horizontal and forms the top of the casing or cabinet, there is room for a great quantity of data and the data and graduations may run all the way around the dial. In Fig. 2 I have illustrated the dial as having the ordinary graduations and numbers, and also having the kilocycles and the designation of the stations located at the proper position.

There is an indicating device 9 mounted on a centrally located shaft, which indicating device is moved around the dial to the indications representing the different stations. I prefer to provide the indicating device with a magnifying glass Ill attached thereto, which passes over certain of the indications, such as the names of the stations, so that they may be easily read. The indicating device as shown in Fig. 2 has an opening therethrough through which the characters which represent the names of the stations may be read, although I prefer to have a magnifying glass extending across this opening. This opening is of the proper size so that when the pointer is at the indication representing the station, the letters of the name of the station will all come within this opening. This also assists in insuring the indicating device being in the proper position for the station, for in addition to the pointer which is to be brought opposite the indication on the dial, the opening is of such size that when all the letters indicating the name of the station are clearly seen through the opening,

the pointer is then in its proper position. This is clearly seen in Fig. 2. In View of the large number of broadcasting stations, these letters and indications must be small and the magnifying glass permits them to be made small so that a large number of them can be crowded upon the dial, whereas, without the magnifying glass, a lesser number would have to be used in order to be legible. Any desired type of radio mechanism may be utilized and I have not attempted to show such mechanism in detail, but have simply attempted to show more or less diagrammatically certain of the operating parts. In this device the control knobs or members are located at the center of the dial and are provided witha shafts which pass through the dial at its center. As herein shown, there is a tuning member H which is connected toa shaft [2-, which has thereon a pinion l3 which is connected by the gears M, l5 and [5 with the shaft I! of the condenser l'la. The gears I 4, l5 and I6 are r'eduction gears for the purpose of permitting the-indicating device 9 to be moved through 360, while the condenser elementsare moved through a muchsmaller arc. The condenser shaft I! is provided with agear 18 which connects with the pinion l9 attached to a sleeve 20 carrying the indicating device 9. There is shown a tone control member 2! which is connected by a hollow shaft 22 with a gear 23' meshing with a gear 24 attached to the shaft 25, connected with the tone control device or resistance 26; There is shown a band switch 21 which is connected by a hollow shaft 23'with a gear 29 which meshes with the gear is attached to the band control shaft 3i. There is shown a volume control and switch 32 which is connected by a hollow shaft 33 with the gear 36 which meshes with the gear attached to the control shaft 36. It will be seen that the radio mechanism may be regulated and controlled as desired and that the indicating device'may be moved to connect with any desired station.

I prefer to provide a transparent protecting device 3! which is'placed over the dial 8 and the indicating device 9, as clearly shown in Figs. 4 and 7. This device has an opening through the center for the various shafts and there is a member 38- fastened to it by means of the plate 3% and the fastening devices M. I prefer to provide some means for lighting up the dial and I have indicated for that purpose the lights M and the reflecting device 42. In Fig. 8 there is indicated' some of the tubes 43 and other parts of the receiving mechanism;

The speaker 44 which is preferably a dynamic speaker is preferably located at the bottom of the casing or cabinet below the bafile member 55 and attached thereto, the baffle member having opening 4% therethrough. The speaker directs the sound both upwardly and downwardly. The sound passes out through the open spaces between the projecting members and passes out in. all directions. 7

I have indicated wires leading to the device and consisting of the ground wire M, the aerial wire 43 and the connection to the electric circuit 48, as passing into the casing at the bottom through openings 5%; I have also indicated the transformer 51 associated with the dynamic speaker.

It will thus be seen that this device may be set out in the middle of the room, if desired, or in any part of the room, and it matters not which portion is presented to view, it will show a com- Cir plete symmetrical, good-looking closed construction. It will be seen that I have here not only a circular dial, but a cylindrical cabinet with the circular dial on top. As clearly shown in Fig. 2, the dial 8 is horizontal and completely covers the top of the casing or cabinet and is provided with indications representing the different stations. There are a plurality of sets of indications associated with this dial, an outer set extending circumferentially around the dial, consisting of numbered graduations, an adjacent inner set extending circumferentially around the dial, representing the kilocycles for various stations, and within these graduations and between them and the center of the dial, are characters or letters representing various stations, the characters or letters of each stations extending in a circumferential direction around the dial. The indicating device 9 has a pointer at the end thereof and an opening between the pointer and the center of the dial, throughwhich the letters or characters which represent the names of the stations are read. As clearly shown in Fig. 2, this opening through the indicating device 9 is of the proper size ina circumferentially extending direction and the letters are so proportioned, that when the pointer is'at the indication representing a given station, the letters of the name of the station are read through this opening. The opening and the letters are so proportioned that the letters which represent the given station, when the pointer points to that station, can all be read through the opening, theseletters preferably extending substantially across the opening in a circumferential direction, the two end letters being substantially at the opposite edges of said opening in a circumferential direction. number of stations on the dial, there are several sets of these letters representing the stations; arranged circumferentially, one within the other, with the letters extending in a circumferential direction around the dial, the letters in the different sets being staggered, so that they can all be used and so that when any one set of letters for one station shows through the opening inthe indicating device, the indicating device will be in the proper position to bring that station in and without interference with other stations; The opening through the indicating device is of sufficient length radially to permit any one of these sets of letters to be seen through it. This opening and the letters on the dial extending in a circumferential direction therearound assist in assuring the indicating device being in the proper position for the station, for when the letters of any given station all show through the opening, the pointer is in the proper position to point to the other indication on the dial representing this particular station. When a very large number of letters representing various stations are used, the magnifying glass permits them to be made small so that a large number of them can be thus crowded upon the dial and yet easily read.
