RADIO CABINET AND INDICATOR Filed April 30, 1945 W W IN VEN TOR.

Patented June 22, 1948 UNITED STATES PATENT OFFICE RADIO CABINET AND INDICATOR William W. Montgomery, El Paso, Tex.

Application April 30, 1945, Serial No. 591,189

- 2 Claims.

This invention relates to new and useful improvements in radio cabinet and indicator. More specifically the invention relates to the dial exposure of the cabinet. In this character the invention has for its provision the arrangement of a dial formed to provide adjacent viewing surfaces arranged in different planes with respect to each other whereby maximum view of the dial may be had.

It is the common practice in the radio art to provide each radio cabinet with a dial. This dial is usually placed either on top of the radio cabinet or in one of its side or end walls. Whether placed on the top or in the side or end walls of the cabinet, there can be had but a minimum degree of view. For instance, when placed in the side or ends of the cabinet, one standing erect and looking down upon the radio cabinet, especially when the cabinet is disposed upon a lower shelf of a table having a plurality of shelves or upon the top shelf of such table, it is necessary to stoop over to a position which will afford a view of the dial. Likewise, if the dial is placed in the top of the cabinet, one whose line of vision is below the 4 top plane of the cabinet will have very little view, if any, of the dial. At any rate, in such position one would not have a view of the dial such as would enable accurate adjustment of the dial,

With these objections to the present type of radio cabinets in mind, it is a principal object of the invention to provide a radio cabinet in which the dial is so situated and is so formed as to provide more than one viewing surface, thereby enabling one to view the dial irrespective of his position, that is, a position erect or a position in which the line of vision is below the top surface of the radio cabinet.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a perspective view of an illustrative radio cabinet showing my improved dial embodiment associated therewith;

Fig. 2 is a perspective view of my dial embodiment;

Fi 3 is a fragmentary vertical sectional detail view showing the method of attaching the dial to adjacent walls of the radio cabinet; and

Fig. 4 is a fragmentary perspective view of a dial embodiment showing a slightly modified form of construction,

The drawings illustrate the preferred form of construction by which the several objects of my invention are accomplished. In these drawings, II! indicates a radio cabinet. This radio cabinet, except as hereinafter pointed out, may be of any approved form or design which includes a loud speaker grille I l and control knobs I3. While I have shown this loud speaker grille I I and control knobs I3 located on the front wall I4 of the cabinet, it is obvious that their position may be changed without departing from the spirit of this invention.

In this cabinet I5 there is provided along one edge I5 thereof an elongated opening it which opens upwardly through the marginal edge ll of the top wall I8 and outwardly through the marginal edge I9 of one of the walls 25] of the radio cabinet II]. This opening I6 is preferably closed by a transparent closure 2| hereinafter referred to as the dial window. The dial window 2| is connected in its position with respect to the radio cabinet I0 in the manner shown in Fig. 3, which includes providing grooves 22 along the longitudinal edges of the window 2 I, for the reception of ribs 23 provided by reducing the longitudinal marginal edge portions 24 of the walls of the cabinet defining the opening I6, In mounting this window 2I in its position as shown in Fig. 3, the window is slightly compressed so as to snap the ribs 23 into the grooves 22 of the window 2|.

A part of the radio chassis is indicated at 24, and this part 24 of the radio chassis supports the dial 25. This dial 25 is bent to present an L- shaped formation in cross section providing a vertical viewing surface 26 and a horizontal viewing surface 21 disposed, as shown in opposite planes with respect to each other. On each of these surfaces 26 and 21, there appears a scale 28 comprising a plurality of markings of equal length and equally spaced from each other and divided into groups by a plurality of markings 29 of a somewhat greater length. At the points 30 of these markings 29, appear the numeral indicia 3 I.

An indicator or pointer is shown at 32, and this pointer is supported by a U-shaped guide 33 in the groove 34 of which extends the edge 35 of the dial 25, the said dial being connected in any suitable manner to the bracket 36, as shown in Fig. 3. This indicator or pointer is connected to a belt or cord 37, which in turn is connected in a suitable manner (not shown) well known in the art, to the dial-operating knob, which may be any one of the knobs I3, the arrangement being such that upon movement of the belt or cord 31, th

3 indicator 32 will be moved over the viewing surfaces 26 and 21.

By the embodiment of a dial construction such as hereinbefore described in a radio cabinet, it is manifest that the angle of view of the dial is greatly increased and that the dial may be read from a position looking down upon the radio or from a position directly in front of it or at an angle with respect to the front of the radio cabinet.

In Fig. 4, Ihave shown a modified-formof construction of the dial. In this form of dial, 38 represents the out-er convex field of an area sufficiently large to provide the adjacent viewing su-rtended, although not necessary, that the tw o viewing fields be separated by demarcation line,

which, in the present instance, maybe. either.
