Claims. (Cl. IIS-129) My invention has primarily to do with the mounting of the dials of radio sets and the fittings therefor, in connection with radio cabinets and the like. I will describe my invention in this connection; although it will be understood that its utility is not confined thereto and that the teachings herein contained may be applied by the skilled worker in the art to other situations which embody like problems, of which there are many.

more expensive variety, there isan ornamental Wooden cabinet which houses the chassis of the radio set. This chassis, of course, embodies the condensers which must be adjustedin the operal5 tion of tuning; and it is quite usual to mount the tuning dial which indicates the tuning, on and as a part of the chassis. is cut in the front of the radio cabinet with relation to this dial, so that when the chassis is in position in the cabinet the dial will be visible through the hole. It is then customary to cover the hole in the cabinet with a suitable piece of glass, held in place by an ornamental rim or bezel. At this point certain problems arise. Since the cabinet is subjected to vibration from the one or more loud speakers employed in con- 'nection with the radio set, it is necessary first to mount the glass in such a way that it will not rattle. In the lsecond place, it is necessaryy to make some sort of connection between the dial mechanism and the radio cabinet such that rattling cannot occur at this point. In the third place, where the dial is 'to be illuminated and is not of the translucent type where the illumination is effective through the body of the dial, it is desirable to provide lor what is known as indirect illumination. Such illumination theoreti- In the modern radio set, particularly of the Therefore, a hole cally constitutes a passage of light through they body of the glass which illuminates the figures on the dial in a sidewise manner. However, such illumination is not very effective if mixed with direct illumination and it is highly advisable to conhne the light to light which does pass through the body of the glass of the dial. This premises 4 therefore a light `tight connection between the cover glass and the glass of the dial, which connection not only must be effective to the end described, but must also be anti-rattling and capable of giving longv and adequate service.

The fundamental objects of my invention are realized, in the solution of the problems hereinabove set forth, by simple, inexpensive but accurate and effective means. These 'and other obiects of my invention, which will be set forth hereinafter or Will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and arrangement of parts of which I shall now describe an exemplary embodiment. Reference is made to the drawing wherein:

Figure 1 is an elevational view of an exemplary installation with parts in section.

Fig. 4 is a perspective view including an end section of a mounting strip member employed by Fig/ 5 is a sectional view showinga slightly different form of strip with other vparts in relaticn thereto.

Referring rst to Figs. 1 and 2, I have indicated thel lines `at I, the body of a radio cabinet. This body is cut out as at 4i so as todsplay a radio dial. It

will be understood that thev particular form of the dial is not a limitation upon my invention. I will, however, describe an exemplary form of dial. shown most clearly in Fig. 2. This dial consists of a metal backing plate 5 suitablyl mounted by brackets 6 with respect to the chassis of a radio set. 'I represents the driven shaft of a condenser` system. The usual operating handle 8 is provided together Awith a suitable transmission, and although not shown in detail, the particular device herein illustrated has a plurality of pointers 9 and I0, there being asuitable vgear ing therebetween so that these pointers move at diierent speeds relative to the drive shaft of the condensers. The position of the more rapid pointer thus gives a sort of vernier indication oi the position of the smaller moving pointer. The particular form of indicator in connection with the dial has nobearing, however, on the present invention. A

The dialA face, in the exemplary embodiment, comprises a card, panel or the like indicated at Il, and bearing the various indicia which go to make up the face of the dial. Covering this panel is a piece of glass I2 through which the panel is visible. The metal piece t in this particular embodiment is of rectangularshape and .the glass member I2 is preferably of they same shape. The panel II, which is opaque, is preferably cut out well beyond the face of lthe dial portion as shown at I3, in Fig. 1; and suitable electric lamps I4 are located behind the cut-out portions and are supported on suitable brackets.

' The purpose of these lamps is to give illumination to the dial. It is a frequent practice to treat the face of the glass I2 overlying the cut out portions I3 to give it a reective character. This may be done by frosting the surface of the glass as at I5. This is effective in directing a large percentage of the light passing through the perforations I3`into and through the glass body I2, giving the effect of indirect illumination. As has `been indicated, however, it is desirable to have some sort of connection between an external atY tion of the means which I employ to gain the effects of my invention. Still referring to Fig. 2, I have indicated at I6 a cover glass, generally of non-planiform shape so as to do away with external reflections, although this again is not a limitation on my invention. The glass is held in a 'strip member I1 hereinafter to be more fully described; and an ornamental bezel I8 is employed, coming up). to the edge oi' the glass and preferably displaying a. narrow illlet or edge portion I9 of the strip.

'I'he strip-is more clearly illustrated in Fig. 4. It is preferably made of rubber or similar resilient material and is molded so asV to provide a narrowy channel 20 to receive the edge of the glass, and a wider channel 2| to receive the edge of the perforation in the radio cabinet. I'he outer leg of the channel 2I will preferably take the form of an enlarged or thickened bead or fillet 22 as shown; and the narrow illlet I9 hereinabove referred to is formed on the outer edge of the outer leg of the channel 20.

The strip shown in Fig. 4, may be made as a plain strip of indefinite length from which pieces of requisite length may be cut and bent into circular shape for accepting cover glasses of diilerent sizes. However, I am not restricted to such a. construction. As will be clear, the mounting for my cover glass, having a cross section such as that shown in Fig. 4, may be molded in the shape of a continuous ring, designed, of course, for the acceptance of a certain size of cover glass and for fitting into a perforation of a certain size in the radio cabinet.

In use the relationship of the strip of Fig. 4 to the other parts is most clearly shown in Fig. 3. The edge of the cover glass I6 is shown embraced in the channel; and the channel 2I is shown engaging the edge of the radio cabinet I. A bezel 23 is shown engaging the outer leg of the channel 20 and displaying the narrow fillet I9. The bead 22 is shown lying inside the,radio cabinet I, engaging and holding the edge of the perforation therein, and also engaging the face of the glass dial member I2.- Here it makes a light tight contact with the member I2 and also provides an anti-rattling positioning means forthe dial. It will be clear that light from the bulb, I4 in order to illuminate the panel II must pass through the body of the glass I2 and that extraneous light is cut oi by the bead 22. It will also be apparent that the cover glass I6 is tightly but resiliently mounted in such a way that it cannot rattle. It will further be apparent that in the construction shown the space inside the cover 4glass I6 is substantially a sealed space protected from the accumulation of dust anddirt, not only from the outside of the radio cabinet, but also from within. It will finally be apparent that the con` struction while solving the problems to which my invention is addressed, is nevertheless, extremely simple and very economical.

Where there must of necessity be considerable space between the glass panel I2 and the body oi' the cabinet I, it is within the scope of my invention, as shown in Fig; 5, to carry the, strip out beyond the bead or fillet 22 for as s'rat a distance as may be desired. This is indicated at 24. Preferably the wall extension 24 will terminate in an additional fillet 25 for the purpose of making a perfect sealing contact with the face of the glass panel I2.

Modifications may be made in my invention i. without departing from the spirit of it.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
