4 Claims.

One object of my invention is to provide a radio cabinet and apparatus in which the apparatus is mounted in a novel manner relative to the cabinet to secure several desirable results which are not obtainable by the usual arrangement of a horizontally arranged panel on which radio apparatus is mounted in the ordinary manner.

Another object is to provide a radio construction in which a panel on which the radio apparatus is mounted is arranged vertically within the cabinet and the apparatus is so arranged relative to the panel that only parts thereof to be removed and replaced, such as the radio tubes, project from an outwardly facing surface of the panel so that access can be readily had thereto, the remaining apparatus being mounted on the opposite side of the panel so that it is not readily accessible, except to a Serviceman after he removes the entire panel.

A further object is to provide a panel which exposes the radio tubes and the like to ready access but substantially encloses the remaining parts of the radio apparatus so that they are protected from dust and are also electrically shielded by the panel, the panel having side flanges to supplement the panel itself as a shield for this purpose.

Still a further object is to arrange the panel in relation to a speaker so that back tones from the speaker can be controlled by the panel and emitted to the cabinet behind the panel desired.

Still a further object is to provide an elongated radio apparatus panel arranged vertically in a radio cabinet so that space is provided in the cabinet at the sides of the panel into which the back tones of the speaker may be emitted, such spaces thereby providing sound chambers for the back tones.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated 45 are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a rear elevational view of a radio cabinet showing radio apparatus mounted there- 50 in and arranged in the novel manner I contemplate, a portion of the back panel or cover of the cabinet being broken away to show the apparatus.

Figure 2 is a horizontal sectional view on the 55 line 2-2 of Figure 1.

1937, Serial No. 167,261

Figure 3 is a vertical sectional view on the line 3-3 of Figure 1; and

Figure 4 is a rear elevational view of a sound board, speaker and modified form of panel.

On the accompanying drawing I have used the reference character C to indicate generally a radio cabinet. The cabinet C is illustrated as of the upright or console type. Within the cabinet C I provide a panel P for the radio apparatus. The panel P it will be noted is arranged in a vertical plane for several important reasons which will hereinafter appear.

The panel P is preferably provided with side flanges l0 and a top flange [2. The panel may be supported in any suitable manner relative to the cabinet C. By way of illustration I show supporting brackets l3 and 14 extending from the side walls of the cabinet C. Complementary supporting brackets I5 and I6 extend from the side flanges ll] of the panel P. The brackets l5 and I6 are mounted on the brackets l3 and M by means of bolts H with resilient bushings of rubber or the like l8 surrounding the bolts to minimize transmission of vibration from the cabinet to the panel.

The panel P is adapted for supporting radio apparatus which may include a variable condenser IS, a transformer and radio tubes 2|. These are shown merely by way of illustration as it is obvious that all the other necessary apparatus of a radio set can be also supported by the panel P. The apparatus disclosed however is supported relative to the panel in a distinctive manner. The tubes 2!, it will be noted, extend from the back side of the panel and accordingly are readily accessible when the back cover 22 of the radio cabinet 0 is removed.

The tubes 2| are the parts of the radio apparatus normally replaced by the user of the radio. Accordingly they are the only parts of the apparatus which I mount so that they are readily accessible although other parts desirable for the user to remove might also be mounted in a similar manner. The remaining parts of the apparatus, such as the condenser l9 and the transformer 20 are mounted on the opposite or front side of the panel P, although where the space is restricted, certain covered portions of the apparatus, such as a coil cover 23 of the transformer 20, may project through the panel as illustrated. An opening 24 is provided in the panel for this purpose.

It is ordinarily not necessary to have access to certain parts of the radio apparatus, such as the condenser l9. Accordingly, it may be mounted on the front of the panel P between the side flanges ill with its operating shaft projecting through the top wall i2 of the panel. In this manner the condenser is elec rically shielded as well as being mechanically shielded from ready access. Of course when it is necessary for servicemen to repair or replace any parts of the radio apparatus mechanically shielded in this manner, he gains access to it in the usual way, such as by entirely removing the apparatus panel from the cabinet.

Within the cabinet C I show a sound board 26. A speaker S is mounted thereon and where the panel P projects down past the speaker, the panel may be provided with an enlarged opening 21 to receive the projecting part of the speaker. The sound board 25 is provided with an opening 28 to permit the tones from the front of the speaker to be emitted to atmosphere in front of the radio cabinet C.

The back tones from the speaker may be controlled so that they pass into the back part of the cabinet. For this purpose louvers 29, or any desired type of opening, may be provided in the panel P through which the back. tones may pass in order to enter the back portion of the cabinet C. The back tones may be further controlled as to admission to the atmosphere by openings 30 selectively arranged in the cover 22 for the back of the cabinet.

As an alternative arrangement, the panel designated as P in Figure 4 may terminate short of the speaker S thereby permitting free emission of the back tones to the cabinet behind the panel. Figure also illustrates elimination opening 24- when the radio apparatus, except the tubes 2|, is mounted entirely in front of the panel.

Mounting the panel as disclosed necessitates a mechanical arrangement to adjust the condenser !9. By way of illustration I show a control disc 3i projecting through a control board 32 of the cabinet C. By means or an arrangement of pulleys, a belt or the like 33 is used to transmit motion from the disc 3! to the shaft 25 of the condenser. vertical arrangement of the panel P also permits space at the sides of the panel, as indicated at 34 in Figure 2, through which the back tones from the speaker S may ascend. Such space is ordinarily cut off by the usual arrangement of radio apparatus panel wherein the panel is placed on a shelf in the cabinet. Thus the vertical arrangement of the panel permits an arrangement of radio apparatus such that only the parts desirable for ready removal are accessible without the necessity of removing the panel from the cabinet. This protects the remaining parts or" the radio apparatus from being tampered with and also shields it electrically as it is enclosed within the panel and its side flanges lil. Such arrangement accordingly secures a number of results without complicating the construction or increasing the manufacturing expense.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of 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.

I claim:
