admission of water, and to provide an article of the character mentioned, which is simple and easy of installation in service and removal therefrom; and to cheapen and simplify the construction of the article.

scale.

Description. i As shown best in Fig. 2 of the drawings,

the protector is constructed from an integral piece of resilient material such as rubber,

. and has 'a handle 7 providedtherefor which at all times is accessible for the removal of the protector when the same is installed in service. At the base of the handle 7 is a flange 8. The flange 8 is somewhat rigid, being intended to firmly hold theprotector in position when forced ithin the outer o ening of the auditory channel of the ear.

he cup-shaped flange 9 is of a more delicate structure and of greater flexibility. The flange 9 conforms to the walls of the channel so as to produce a vacuum when drawn Fig. 2.;is a similar-view on an enlarged therefrom. This serves to prevent, the accidental dislodgment of the protector.

When the protector is installed in service, as shown in ig. 1 of the drawing, it will be found that it does not im air the hearing of the wearer, due to the act-that the material is flexible enough to respond to all of. At the the atmospheric sound vibrations. same time it would serve to resist any undue concussion. Also it prevents cold drafts of air passing to the interior of the ear, thereby preventing ear disorders. It serves "to prevent the admission of water when the wearer is swimming, thus overcoming or avoiding many of the ills produced by the accidental admission of water to the ear.

While the article is described as constructed of rubber, I'do not wish it to be understood as being limited to the use of such material. Many other substances may be found desirable. All of such materials I consider as being within the scope of the present invention.

Olwim.

As an article of manufacture, an ear drum protector comprising a handle portion; a cup-shaped flange for insertion in the auditory channel of the human ear, said flange being outwardly tapered to a thin edge for collapsing to conform with the varying sizes of said auditor channel; anda resisting flange intermediate said cup-sha d flange and the exposed end of said hand e for l1miting the insertion of said cup-shaped flan e within said auditory channel, said han e and said flanges being integrally, formed from a resilient material, said elements be in made of different thicknesses to ofl'er di erent resistances.
