Booth, Columbus, Ind., assignor to Nob ‘ litt-Sparks Industri s, Inc., Columbus, Ind., a corporation of Indiana Application November 30, 1934, Serial No. 755,285 5 Claims. (01. 250-16)’ My invention is concerned with radio appa ratus and has for its particular object the mount ing of ?xed condensers and similar parts in the chassis of the radio set. More speci?cally, it is 5» I. my object to produce a mounting for a condenser or similar part which will provide ?rm support and which may be economically and simply con structed._ ‘ In carrying out my invention I provide on the 10 condenser or other part to be supported an out wardly extending annular ?ange which may be formed on a. ring which is secured to the sup ported part. At the place where the part is to be mounted, Iprovide the chassis-frame with an 15 opening of a diameter larger than the part itself but smaller than the outer diameter of the annu lar ?angeon the ring; and, I provide means for ‘ clamping the ?ange to the chassis-frame. The accompanying drawing illustrates three 20 embodiments of my invention: Figs. 1 and 2 are end and side elevations respectively of a condens er mounted in a chassis-frame; Figs. 3 and 4 are views similar respectively to Figs. 1 and 2, but showing a modi?ed form of mounting; Fig. 5 is 25 a view similar to Fig. 3, but showing the condens er in the process of being inserted into its mount~ ing; and Figs. 6 and 7 are views similar respec tively to Figs. 1 and 2, but showing a modi?ed form of condenser. 30 In the arrangement illustrated in Fig. 1, my may be removed from its mounting without the necessity for completely removing the screws 16 from the chassis-frame M. The arrangement illustrated in Figs. 3, 4, and 5 is similar to that shown in Figs. 1 and 2 ex cept for the means employed to hold the ?ange [5 on the ring 12 against the face of the chassis frame I4. In this arrangement, the chassis frame 14. is provided at diametrically opposite points withv two struck-up ?ngers 20, the free 10 ends of which are directed inwardly to overlap the ?ange l5 when the condenser is in place. The ?ange 15 on the ring is interrupted or notched at diametrically opposite points, as indicated at 2|, so that by rotating the condenser to bring 15 the interruptions or notches into juxtaposition with the. ?ngers 20 the condenser can be re moved from association with its mounting by axial movement. If desired, the condenser-re ceiving opening in the chassis-frame may be shaped, as indicated in Fig. 5, where the con denser is shown in process of being inserted, to permit the complete passage of the condenser 0 and its ?ange I5 through the chassis-frame, thus making it possible to insert the condenser into 25 its mounting from either side of the frame. The construction illustrated in Figs. 6 and '7 is substantially identical with that shown in Figs. 1 and 2 except that the condenser, instead of having a metal enclosing shell, is provided exte- 30 mounting is shown as supporting a ?xed con riorly with a covering 25 of paper or other simi denser having an outer sheet-metal shell 10. lar material suitably impregnated with an insu Intermediate its ends, the shell I0 is provided exteriorly with a peripheral bead ll forming a lating agent.
