Patented Feb. 9, 1932 UNITED STATES EDWARD B. NEWILL, OF DAYTON, OHIO,
ASSIGNOR TO GENERAL MOTORS RADIO CORPORATION, OF DAYTON, OHIO, A CORPORATION OF OHIO ELECTRICAL APPARATUS Application filed November 14, 1930.
This invention relates to a control for a radio receiver and more particularly to the mounting of the rotary parts.
An object of this invention to simplify E the construction of a control for a radio receiver so as to reduce the labor, the number of parts, the material, thereby decreasing the cost without a sacrifice in the perilin'mancc.
Further objects and advantages of the present invention will be apparent from the following dcsc 'iption, reference being had to the accompanying drawings wherein a preferred embodiment of one form of the presentinvention is clearly shown.
In the drawings:
Fig. 1 discloses a fragmentary plan view of a control for a radio receiver.
Fig. 2 discloses a sectional view taken along the line 22 of Fig. 1.
Figs. 3 and 4 disclose sectional views taken on the lines 33 and 4-4 of Fig. 2.
In the drawings, the reference numeral 10 indicates the frame of a radio receiver. This frame is preferably made from sheet metal that has been pressed or formed in dies into the desired shape. Mounted on the frame 10 is found the radio apparatus such as the tuning elements 12 vrhich may be any variable impedances such as variable condensers that are adjusted by rotating a shaft 14 carrying a disc 16 which may have an indicator dial mounted thereon and visible through a suitable Window in the panel 18. The dial and the window have not been shown in this modification for the reason that this forms no part of the invention.
It is oftentimes desirable to drive the disc 16 so as to adjust the tuning elements found in the casing 12 through a suitable driving mechanism such as belts or friction devices which are mounted on a shaft 20 extending through the panel 18 and provided with a knob 22 mounted on the outside of the pane 18.
In the preferred modification disclosed in the drawings, a collar 24 keyed to the shaft 20 carries a pair of flexible discs 26 and 28 that straddle and grip the disc 16. The discs 26 and 28 are inserted on the reduced portion Serial No. 495,593.
30 of the collar 24 and held in position by the overspun portion 32. It can be readily seen that as the shaft 20 is rotated the disc 26 and the disc 28 will rotate therewith and cause the driving disc 16 to rotate thereby adjusting the tuning elements. The discs 26 and 28 may be made from any suitable fleX- ible material such as bronze or the like. The foregoing parts are not claimed per se in this application for the reason that these form the subject matter of a copending application to J. Q. 'L-l-aubert, Serial No. 498,340, filed November 26, 1930.
A pair of U-shaped straps 40 and 42 have been drawn from the sheet metal frame 10 as best seen in Figures 3 and 4. The U-shaped straps 40 and 42 function as bearings for the shaft 20. It can be readily seen that this operation which may be performed by suit able dies saves the conventional bearings,
supports for the bearings, and the means for attaching the supports to the frame. After the shaft 20 has been inserted into the position disclosed in 2, 3 and 4, a tongue 43 struck out of the material of the frame 10 is depressed into an annular groove 44 upon the shaft 20 thereby preventing endWise movement of the shaft 20. It can be readily seen that by this arrangement no collars preventing endWise movement and no bearings aside from those integral With the frame 10 are required.
While the form of embodiment of the pro ent invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming Within the scope of the claims which follow.
\Vhat is claimed is as follows:
1. In a control for a radio receiver having a sheet metal frame, the combination including U-shaped straps integral with said frame, and a shaft rotatably supported in said U-shaped straps so that said straps function as bearings for said shaft.
2. In a control for aradio, a sheet metal frame for supporting the radio apparatus, U-shaped supports integral with said frame, a control shaft journalled in said U-shaped straps, said shaft having an annular groove,
a tongue integral with said frame extending into said groove so that the shaft is mounted for rotary movement and limited in axial movement, and control driving mechanism mounted on said shaft. 7
In testimony whereof I hereto affix my signature Y ,e
