Application January 29, 1934, Serial No. 708,927 1 Claim. (Cl. 250—14) The invention relates to radio apparatus. inwardly extending flange 8 of the dial support One of the main objects of the invention is to 1 by screws IS. provide a novel operating means for control of I The member 3 is adapted to rotate on the dial such parts as the tuning, volume or tone. Ac support and is adapted to have its rotary move 5 cording to the present invention, the control op ment translated to the tuning condenser bank I‘! 5 erating means is made in the form of a ring through any suitable operating connections. As or annulus which may be used in different as here shown, the member 3 has an annular spur , sociations with other parts of the apparatus and which lends itself more readily to a symmetrical 1O arrangement of parts and a more pleasing de sign of the cabinet or control panel. A further object of the invention is to pro vide a radio apparatus in which the operating gear l8 secured thereto by screws I9, said gear acting also as a retainer member for holding the member 3 against endwise movement relative to 10 the support 1. This gear l8 meshes with a gear 20 mounted on the control shaft 2| of the con denser bank I1, the ratio of the gears I8 and 20 means for one of the controls forms a frame compact and pleasing arrangement. being of any suitable value. For the volume control, I have shown the con- 15 trol unit 22 disposed in the speaker opening with The invention further consists in the several features hereinafter set forth and more par its shaft projecting through a support portion 23 and having the exteriorly disposed operating ticularly de?ned by the claim at the conclusion knob 24 thereon. The portion 23 is here shown as an extension of part of the material forming the 20 15 about the speaker opening and thus provides a 20 hereof. In the drawing: dial 4, the control being suitably clamped thereto. Fig. 1 is a front elevation view of a control oper The opening for the speaker may be protected by the screen 25 here shown as secured to the back face of the dial 4. From the foregoing description, it will be noted 25 that a rotation of the member 3 will through the gears I8 and 20 turn the tuning control shaft 2| so the desired station may be heard. While the member 3 has been shown as con nected to the tuning control, it will be under- 30 ating means embodying the invention; Fig. 2 is a detail sectional view through. a por 25 tion of a radio cabinet with the control operat ing means shown in vertical section. Referring to the drawing, the numeral 3 desig nates the annular control operating member gen erally and 4 the dial associated therewith, said 30 member 3 having a pointer 5 cooperating with the indications B on the dial. The indications here shown are for wave length, the control being a tuning control. As herein shown, the dial 4 is formed or se 35 cured to an annular supporting portion ‘i hav ing an inwardly extending annular ?ange 8 and a short outwardly extending annular ?ange 9 seating in an annular guide recess [0 in the con trol member 3, these parts being mounted in the 40 opening H in the wall [2 of the cabinet for the speaker l3. For supporting the speaker and the parts 3 and 4 in position, a spider I4 of metal or other suitable material is secured to the wall of the cabinet by screws I5 passing through arms l5’ (one being shown) and to the speaker and the stood that it may be used as the operating mem ber for other controls of the apparatus such as the volume control or the tone control. I desire it to be understood that this invention is not to be limited to any particular form or 35 arrangement of parts except in so far as such limitations are included in the claim. What I claim as my invention is: In a radio apparatus, the combination with a cabinet having an opening for the speaker, of a 40 control operating member surrounding said opening, an annular dial cooperating with said member and disposed within the‘same, and oper ating means for the volume control within said opening and inside the projected area of said dial.
