UNITED STATES PATENTOFFICE. JAMES M. WAGNER, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGN- MENTS, TO WILLIAM L. MCKAY, OF CHICAGO, ILLINOIS.
TELEPHONE-RECEIVER. APPLIANCE,
Specification of Letters Patent.
PatGIItGd'NOV. 11, 1919.
' Application filed August 14, 1916. Serial No. 114,781.
provements in Telephone-Receiver Appliances, of which the following is a specification.
This invention relates to devices designed for application to telephone receivers and having for its object to improve the hearingand to exclude extraneous noises from the ears.
The present invention is an lmprovement in a similar device which. is the subject mat ter of an application for Letters Patent filed May 27, 1916, Serial No. 100346, and it consists in a novel combination and arrangement of parts to be hereinafter described and claimed. 1
In order that the invention may be better understood, reference is had to theaoc'om panying drawing forming a part of this specification.
In the drawing,
Figure 1 is a perspective view of the device showing the manner in which'it is used, and
Fig. 2 is a cross section thereof.
Referring specifically to the drawing, 5
denotes a sound-receiving member which is constructed so that it maybe attached to the telephone receiver 6. The member 5v is a circular block of any suitable material, having a central cavity 7 on one side over which the ear end of the receiver 6 is placed.
From the cavity 7 extend two ducts 8 which open through the edge or side of the member 5. These ducts are diametrically opposite and they extend from the cavity in opposite directions.
To the end of each duct 8, where it opens through the side of the member 5, is fitted a short rubber or other flexible tube 9 carryin a metal or other rigid sound-conducting tube 10 having at its outer end an ear-piece 11 for insertion into the ear. The two tubes 10 are spaced laterally and their outer ends have inward bends toplace the ear pieces in proper position for insertion into the ears.
Between the tubes. 10 is located a bowed spring 12 secured at its ends to the respec tive tubes, and having a normal tendency to draw the two tubes together.
In use, the member 5 is.held over the 'mouth or ear end of the receiver 6, one hand holding the receiver and also holding the member 5'thereon. It will be understood, of course, that the side of the member 5 having the cavity 7 will be placed against the receiver. This side of the member 5 has a raised portion 13 through which the cavity opens, and this raised portion 13 is inserted into the mouth of the receiver. The part 13 tapers outwardly so that it readily fits various makes of receivers and it also fits snugly sothat no sounds escape from the cavity except through the ducts 9.
To apply the device to the ears the tubes 10 arespread sufficiently to allow the parts 11 to be inserted into the ears, the spring 12 holding the device in this position, so that the one hand of the user is left free to grasp the receiver and hold the member 5 thereagainst, and the other hand is left free to make notes. The ear pieces exclude all extraneousnoises fromthe ears, and the tubes 9 and 10 conduct the sound issuing from the receiver 6 to both ears. The sound issuing from the receiver enters the cavity 7 and passes through the ducts 8 into the tubes 9,
and then passes through the tubes 10 to the ear pieces 11. Because of better hearing, continuity of conversation is assured, and the device is therefore a valuable accessory in noisy places, and it also makes a telephone available to persons with defective. hearing.
The device is simple, and can be readily applied to any ordinary telephone receiver without making any changes in the structure or the shape thereof.
I claim A telephone receiver appliance comprising a sound-receiving member shaped on one side to fit against the ear end of the re ceiver and having on said side a cavity adapted to communicate with the receiver the flexible tubes, ear pieces on the outer ends of the sound-conducting tubes, 'and a bowed spring connected at its ends to the rigid sound-conducting tubes and positioned 5 therebetween, said spring having a normal .tendency to draw the sound-conducting tubes together, whereby said. tubes are held in operative position supported by the ears of the person when the sound-receiving member is disengaged from' the receiver. 10
In testimony whereof I affix my signature.
JAMES ,M. WAGNER.
