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.
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
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
