UNITED STATES CHARLES KUEILOF CHICAGO, ILLINOIS.

RECEIVER snrron'r roa'sounn AMPLIFIERS.

Application filed May 1,1922. SeriaI No. 557,663.

To all whom it may concern:

Be it known that I, CHARLES KUEN, a citizen of the United States, and a resident of Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvement in Receiver Supports for Sound Amplifiers, of which the following is a full, clear, and exact description.

My invention relates to improvements in receiver supports for sound amplifiers, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device of the character described in which means is provided for yieldably holding telephone receivers, such as used in a radiophone receiving set, and directing the sound waves therefrom to the amplifying horn of a phonograph or'the like.

A further'object of my invention is to provide a device. of the character described which may quickly and easilybe attached to the ordinary type of phonograph amplifying horn in place of the) ordinary type of phonograph reproducer.

I A further object of my invention is to provide a device of. the character described which may be made of a single piece of stock, and which is relatively cheap to manufacture.

Other objects and advantages will appear in the followin specification, and the novel features of the invention will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying drawings forming part of this application, in whicha Figure 1 is a plan viewof an embodiment of my invention partially in section with one receiver in. place, and

Figure 2 is a sectional view along the line 2-2 of Figure 1.

In carrying out my invention, I make use of a Y-shaped tubular body member 1. The

body member 1 and the remainder of'the device, as hereinafter described, is composed of a partially vulcanized resilient rubber.

At each end of the shorter branches 2 and 3 of the body member 1 is provided an integral cup-shaped member 4. The members 4 are circular in shape and are centrally located upon the branches 2 and 3 of the body -member; 1. The bottom walls 5 of the members 4 are frelatively thick, whilefthe side member 1,- as shown at 11, is provided with an annular rabbeted portion 12 on the inner walls thereof. The purpose-of the rabbeted portion 12 is toladmit the mouth of a tone amplifying horn 13 of the phonograph or the like. The rabbeted portion further prevents the mouth 13 of the horn from being placed too far into the body member 1. rom the foregoing description of the various parts of the device, the operation thereof may be readily understood. In using my receiver support, I first remove the mechanical reproducing mechanism from the phonograph tone armand place the body member 1 so that therabbeted portion 12 encompasses the mouth 13 of the tone' arm.-

I then place a telephone receiver 8, such as used inthe ordinary type of radiophone receivingsets, in the cup-shaped member 4.

' This is done by manually stretching the resilient sidewalls 6 of the member 4 and slipping them'over-the cap 14 of the receiver 8. The side walls 6 are then released and they assume a positionin close engagement with the'caps 14, as shown in Figure 1, thus shutting-out all outside noise and assuring the' positive travel of the sound waves through the body member 1 and ultimately into the mouth of the tone arm 13. The annular ridge 9 further acts as a means for confining the sound waves to the body memher 1 inasmuch as the ridget) is at all times in close'contact with the outer wall 15 of the receiver cap 14.

I then place a second receiver in the remaining member 4 and the device is ready for operation; When the radiophone set is in operation, the receivers 8 actuate to reproduce sound waves which travel .from each of the receivers through the portions 2 and 3 of the member 1, and to the mouth of the tone arm 13.

I claim:

A device of the character described comprising aY-shaped tubular sound conducting member constructed of resilient rubber; one branch of said Y-shaped member being tapered outwardly from the body portion thereof, and having a rabbeted portion on 5 the inner Wall at the mouth of the branch,

and integral cup-shaped supporting members carried by the remaining branches of the tubular member at the outer ends thereof for yieldingly supporting a pair of telephone receivers, said cup-shaped portions having their sound conducting passages arranged to register with the sound conducting passage in said telephone receivers.

, CHARLES W. KUEN.
