Application September 21, 1937,

' 9 Claims. (01. 179-107) This invention relates to telephonic, devices for assisting or enabling partially deaf persons or persons whose hearing is impaired, to hear, and more particularly to means for holding such hearing assisting devices in proper position and with proper tension against the head of the user.

In such cases where deafness is not accompanied by impairment of the auditory nerve, and is due solely to defects in the ear structure, it is There are many telephonic devices of various shapes and manufacture on the market, known generally as audiphones, and the most practical and successful of these are those of the type which act on the mastoid temporal bone.

Various types of apparatus have been devised for holding such audiphones in place, and with proper pressure against the mastoid temporal present in general use are awkward and cumbersome in appearance'and in many instances uncomfortable to wear.-

Attemptshave been made to incorporate the audiphones in eye-glasses but such attempts heretofore made have required specially constructed eyeglasses, specially constructed audiphones, and the audiphones have been incorporated in'the eye-glass structures as a part thereof, and one could not be used without the other.

The primary object of the present invention is to provide a convenient, neat-appearing, inconspicuous device for holding an audiphone in proper contact with the mastoid temporal bone of .the user.

More specifically, anobject of the present invention is to utilize eye-glasses of ordinary construction, and particularly the ear-pieces or bows thereof, to which is detachably attached a carrier member shaped and designed to receive the particular'make'of audiphone preferred by the user, and constructed so that the audiphone and/or the carrier may be attached to or detached from the glasses as desired. i

It has been found that the ordinary construction of eye-glasses does not provide suflicient pressure to hold an audiphone in the proper tensioned contact with the mastoid temporal bone, and it is therefore'another object of the present invention to provide novel changes in the construction of eye-glasses, which will in no wise interfere with their efiiciency, to provide suflicient tension or pressure and insure proper contactof the struction of Serial No. 164,857

audiphone or hearing device with the bones of the head of the user.

With these and other objects in view, as may. appear from the accompanying specification, the invention consists of various features of con- 5 In the drawing:

The present invention is extremely simple in construction, operation and use and consists essentially in the combination 1 features, namely the provision pensive, practical device by means of. which an audiphone may be attached to bone to provide the necessary transmission of sound vibrations through the bone to the auditory nerve, and in the drawing are shown certain '55 in the carrier.

types or shapes of carrier members designed to properly tit and carry well-known types of audiphones, but it is to be understood that the invention is not limited to the shapes of carrier shown or to any particular shape of carrier, but embraces the broad idea of the carrier as hereinafter more specifically described for use in connection with any of the many types of audiphones now on the market.

The carrier, one form of which is shown in Figures 1 to 4 inclusive, comprises a body i which includes a back plate 2 shaped preferably to conform to the shape of the audiphone, indicated at A, but if it is so desired the carrier may e of any desired shape, in the present instance, oblong or oval. The back plate I has sides 3 formed thereon which are bent or extend substantially at right angles to the back plate 2 and are tensioned or constructed so as to frictionally grip the audiphone A and hold it securely in position As clearly shown in Figures 2 and 4 of the drawings, the frictionally gripping sides 3 extend only partway over the edges of the audiphone A so as to leave the plug receiving sockets B exposed to receive the plugs C of the hearing device.

The carrier I has thereon which is rolled or formed from the same piece of material of which the carrier l is made and is provided with sufficient tension to frictionally grip the down-turned portion to of one of the bows ll of a pair of glasses l2. The attaching sleeve 5 is open at both ends so that it may be slipped over the end in of the bow H for attaching the carrier to the eye-glasses i2. The provision of the frictionally gripping attaching sleeve 5 will also permit the carrier I the audiphone to be disconnected from the eyedesired, allowing the eye-glasses to be used independently of the hearing device.

The usual construction Qfeye-glass does not provide sumcient lateral tension to the bows, for holding the audiphone or hearing device against the head bone of the wearer with sufflclent pressure to insure the proper transmission of the sound vibrations to the bone and from thence to the auditory nerve, and in the form shown in Figure 2 of the drawing a very simple alteration is made to the eye-glasses, which can be made to practically any approved type of eye-glasses having suflicient body and stability to carry the hearing device, by any one and at practically no cost. The bows of the eye-glasses l2 are attached to the frame i5 by hinges i5 and the hinge extensions i6. Normally the hinge extensions it: are substantially in the same plane as the frame M of the glasses, and the bows H normally extend substantially at right angles to the frame as shown at the right-hand side of drawing. By bending the hinge extension ii to which the audiphone carrying body I i is hinged, at an abrupt angle to the frame ll so as to reduce the internal angle between the frame 14 and the body i i, additional side tension isprovided through the body II when it is forced outwardly to fit tension which is provided by the resiliency of the bow and its increased inward inclination will press the audiphone or bearing device A against the mastoid temporal bone of the user with suiiicient pressure to insure the proper transmission of the sound vibrations.

If the particular vice requires it or application of the hearing deit is found desirable to do so bow inwardly on an attaching sleeve 5 formed a to fit a different preferably being rolled or formed along the side of the head of the.

both of the hinge extensions on the frame oi! the eye-glasses may be bent as shown in the drawing and thus on the opposite side of the head of the wearer. Also the present invention embraces the idea of bending the bows of the eye-glasses to provide the necessary or desired pressure against the head of the user of the hearing apparatus.

Figure 10 of the drawing shows a modified construction of the eye-glass structure .and in this form a spring is provided which is connected to the hinge extension it of the eye-glasses and to the bow II' for urging the its hinged connection towards the bridge or center of the eye-glasses and provide the lateral tension to the bows, through the medium of the spring, for holding the audiphone or hearing device against the bone in the head of the user with the necessary pressure] In the modified form shown in Figures 5 and 6 of the drawing, the carrier l' comprises a body 2, shaped like the body 2 to receive the audiphone indicated at A and it has the inturned sides or edges 3 for frictionally gripping the audiphone and holding it. The edges 3' terminate intermediate the sides of the audiphone A so as to permit the attachment of the wire plugs C to the audiphone. This far, the modified form of the carrier is the same as the form shown in Figures 1 to 4 of the drawing. It has, however. a different structure for attaching it to a bow of a pair of eye-glasses. To permit attachment of the carrier i' to a bow indicated at E, a tube 22 is formed upon or attached to one of the sides of the how 2', preferably centrally of the side as shown in Figure 6 of the drawing. The tube 22 extends laterally from the how 2' and has its outer end open so that it may be slipped over the body E for securely attaching the carrier i to the bow.

Figures '1, 8 and 9 show a slight modification of the carrier but all of the essential features of this modification are the same as those of the other forms heretofore described and the modification is due merely to the fact that it is shaped type of audiphone than that shown in Figures 1 to 4 inclusive.

, The carrier shown in Figures 6 to 8 inclusive includes a body having its edge portions 3| extending at angles to the main body so as to frictionally engage the audiphone indicated at D and hold it in place in the carrier and against the mastoid temporal bone of the user. The body 30 has an attaching sleeve 32 formed thereon, from the same carrier body is 32 is tensioned a pair of eyepiece of material of which the formed and the attaching sleeve for gripping one of the bows of glasses as indicated at 33 for attaching the carrier and the audiphone to the eye-glasses. The sides 3| of the carrier 30 extend downwardly over the body of the audiphone D only a sufficient distance to provide the necessary frictional gripping engagement with the audiphone and they leave sufficient space to permit unimpeded attachment of the plugs C to the audiphone.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown but that they may be widely modified within by the claims. I
