GEBMICIDE LINING FOR MOUTHIECES FOR VOICE-TRANSMITTENG- INSTRUMENTS.

Specification of Letters Patent. Application filed. July 14, 1908. Serial No. 143,515.

Patented March 2, 1909.

I Be t known that i, Anonsrus A. WIL- LIAMS, a citizen of the United States, reslding atCharlotte, in the county of Meclrlenvented certain new and useful Improvements in Gerlnicide Linings for Mouthpieces for Voice-Transmitting instruments, of which the following is a specification.

My invention relates to an improvement in the method of making voice transmitting mouthpieces or similar devices gerinicide or antiseptic where disease germs are likely to breed and to be gnopagatcd from one person to another While in the act of talking, and my objects are-lirstz to provide a plurality of removable antiseptic or gcrinioide linings for voice trammitting mouthpieces in order that the mouthpiece may be made antiseptic or germv proof without reducing the maximum amplitude of the sound wave to an objectionable extent; second: to provide a means to prevent saliva from enteringihe voice transmitting clement; third: to provide a removable means for securing said burg and State of North Carolina, have in i l pieces to which they are to be attached; fourth: to provide a means whereby one or more of said linings may be readily rcoheap construction of said lining so that the same may be made cheaply in order that they may be destroyed after being used a desired length. of time.

With these objects in view, my invention 1 consists'in certain novel features of construction and arrangement of parts as will l hereinafter be more fully described and pointed out in the claims, reference being had to the accompanying drawing, forming part thereof, and in which Figure 1 is an elevation of a voice t-ansl l l l l l l l I l mittingmouthpiece showing the method of securing the linings therein by an elastic band. Fig. 2 is a view of the elastic band; Fig. 3 is a section 9-10 of Fig. 2, and shows a plurality of linings arranged in a mouthpiece, and Fig. t is a view showing an individual lining.

Similar figures refer to similar" parts throughout the several views.

Referring to the figures, 1 designates a. voice transmitting mouthpiece and whichl it is desired to be made antiseptic or germ proof, and is shown as the ordinary telephone transmitting instrument 9. and to which my present invention is particularly applicable; 5 designates alining made of some cheap material, such as paper, and which is adapted to be treated with some antiseptic or germicide solution. It has the shape-of a. frustun'i of a cone, the sides being slightly concaved so as to take the form of the inside of the mouthpiece 1; 6 designates the upper base of the frustnm and is provided with an aperture 11 therein. The aperture 11 is of such diameter as to readily allow the sound wave to to the transmitting element without reducing the amplitude of the sound waye to an objectionable extent, and is smaller in diameter than the upper of the frustum. The lower base 0!? the frustum shaped lining 3 is vertically turned forming the part 7 and is adapted to fit over the periphery of the mouthpiece 1.

s: designates an uncompleted loop of an elastic band, preferably of metal, the terminal pmrtious 8 extending si'lbstantially in opposite direction and each also forming an uncompletcd loop, which is adapted for finger engagement.

designates prongs which are rigidly attached to the band 1: and extend forward and inward over the end of the mouthpiece, which serves to prevent the band at from slipping hack oil the part 7 of the lining 3.

The thickness of the linings, as shown in Figs. 3 and 4-, is somewhat exaggerated, and in practice would be made of thin material. The conical shape of these linings allows a plurality of them to be telescoped together, as shown in Fig. 3, and it is obvious can be readily inserted in a voice transmitting mouthpiece, as shown. The aperture 11, as heretofore described, allows the sound wave to readily pass to the transmitting element. These linings can readily be made antiseptic or germ proof by the ordinary methods, as are understood by those skilled in that art, and thus accomplishii'ig the aforesaid first mentioned object of my said invention.

As shown in Fig. i, the aperture 11, in the upper base of the frustum, is smaller in diameter than the upper base, the remaining part therefore acts as an obstruction to any saliva that may have a tendency to converge and s to me v:
