INDICATING MEANS FOR RADIO APPARATUS.
Application filed Kay 19,
In radio apparatus which is mounted on a panel board, it has been the practise to mount, on the front of the panel, dial knobs for operating the various devices that are mounted on the backof the panel board.
These dial knobs are usually providedwith certain markings to indicate the relative position of the piece of apparatus being controlled by the control handle or dial. My
invention, therefore, relates to indicating means usedin connection with such radio apparatus.
It is one of the objects of my invention to provide an improved and novel arrangement for indicating the position of the apparatus mounted on back of the panel.
My improvement will be clearly understood by a reading of the attached specification taken in connection with the drawings,
wherein:
Figure 1 is a fragmentary View of the front part of a panel showing a part of the indicating means. 7
Figure 2 is an enlarged sectional view on the line 2-2 of Fig. 1.
Figure3 is a plan view of Fig. 1 showing a piece of apparatus in skeleton form mounted on the back of the panel together with the indicating means.
Figure4 is a view similar to F 2, but in modified form.
Figure!) is a plan view of the holder constituting the part of the indicating means.
Figure 6 is a view of the holder with the cooperating transparent member assembled in position ready to be mounted on the panel board. I
In the drawings, 1 is a portion of a panel board on the back of which radio control apparatus is to be mounted. As shown in Fig. 3, the skeleton form of a variable condenser is illustrated, this being held to the panel 1 by spacing studs 2 and 3 and screws or nuts 4 and 5. A shaft 6 is adapted to ass through the anel and to have fastene on the outer en on the face side of the panel, a control knob 7. I preferably construct the panel 1 out of metal giving the same suitable finish. On various portions of the panel,
there is pressed outwardly, a'portion having a flat surface 8 which issubstantially par alll with the face of the panel and which slopes ofl toward the panel as indicated at 9. The annular slopin portion 9 is so formed as to simulate the ange portion of the dial the opening 11 in the panel 1. The holder 12 15 very readily discernible through the 1925. Serial No. 31,466.
knob which is ordinarily mounted on the front of the panel. The base portion 10 of the knob 7 is preferably somewhat smaller in diameter than the flat portion 8. The sloping portion 9 has an opening 11 punched or formed therein, this opening being preferably positioned as indicated in Fig. 1.
On the back of the panel there is a holder 12 which has an opening to registerwith is provided with a suitable number of clips 13 which are bent over as indicated at Fig. 6 to hold in position a transparent member 18 such as a piece of celluloid. The holder 12 is provided with an indicating finger 14 so that when the holder is attached to the back of the plate 1, by means of the clips 19 and 20 in an satisfactory manner as by soldering, the lndicati'ng finger 14 will be substan tially in the center of the opening 11 in the panel.
Securely mounted on the shaft 6 is a plate 15 which has thereon suitable indicia 16 shown in Fig. 1. Where the plate. 1 is formed, in the manner heretofore described, I prefer to form the dial plate 15 in a similar. manner so as to fit in or snugly around the offset portions of the panel board and closely adjacent the holder 12 whereby the indicia 16 can be seen through the opening in the panel 1. The indicating dial 15, in the form shown in Fig. 3, is preferably made of metal, although, this ma be of any suitable transparent material an when so constructed I mount a lamp 17 on the back of the panel so that when the radio set is in operation, the lamp 1? will be lighted and will illuminate the transparent dial making the indicia on the dial opening in the panel board.
In the form shown in Fig. 4, the panel 1 is not offset and the dial'15 is flat,which construction ma be used particularly when the source of iluminant is used behind the indicating dial.
While reference is made only to the panel board and the apparatus mounted thereon, it is to be understood that the panel board is to be mounted in a cabinet such as ordinarily used in radio receivin sets, so that one lamp 17 may be even so cient for the entire receiving set.
As described it will be apparent that my improved indicating means is particularly adapted for use in connection with radio receiving sets, and it will be further understood that the details for carrying my invention into practise may be varied without departing from the spirit of the invention -or the scope of the appended claims.
Having thus described my invention what I claim is:
1. Indicating means for radio apparatus comprising; a mounting panel having a portion offset from the plane of said panel to simulate the flange of a radio dial, said offset portion having a fiat part substantially parallel with the panel and a sloping part, said sloping part having an opening therein, a transparent member attached to the back of the panel over said opening and an indicating dial movably mounted adjacent said transparent member on the back of the panel, said dial being formed similarly to said panel ofi'set portion.
2. Indicating means for radio apparatus comprising; a mounting panel having a portion offset from the plane of said panehsaid ofi'set portion having an opening therein, a holder attached to the back of the panel and having an opening registering with the opening in the panel, and an indicating finger, a transparent member carried by said holder and a dial movably mounted on the back of the panel adjacent said transparent member and having indicia adapted to pass by said opening and said indicating finger.
3. Indicating means for radio apparatus comprising; a mounting panel, an opening therein, a holder attached to the back of the panel and having an openin to register with said panel opening, said Iiolder carrying a trans arent member over said opening, a plate 0 transparent material movably mounted back of the panel adjacent said openin and having indicia adapted to pass by sai opening and means for illuminating the area around said plate so the indicia. thereon will clearly show tlirough said openmg.
In testimony whereof I aflix my signature.
GEORGE L. LANG.
