ANTISEPTIC ATTACHMENT FOR TELEPHONE-MOUTHPIECES.

Specification of Letters Patent,

Patented Mar. 9, 1915.

Application filed May 13, 1913. Serial No. 767,276.

To all whom it may concern Be it known that I, IRVING S. ROSENBLATT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Antiseptic Attachments for Telephone-Mouthpieces, of which the following is a specification.

The object of the present invention is to provide a cheap and simple germicidal device for attachment to the mouthpiece of a telephone or the like.

In the accompanying drawing, Figure 1 is a longitudinal section of a mouthpiece equipped with my invention; Fig. 2 is a front view of the same; Fig. 3 is a rear view of the device detached from the mouthpiece.

Referring to thedrawing, 1 indicates a telephone mouth-piece of the ordinary construction, and 2 indicates a holder for solid disinfectant material 3. The holder 2 is made out of a single piece of sheet metal, cut and pressed into an annular form, having a central aperture coaxial with that of the mouth-piece, and a cylindrical flange surrounding the margin of the front portion of the mouth-piece. From said flange are cut at suitable intervals, and pressed inward, fingers 5, which, on account of the metal being somewhat resilient, can be pressed outward to permit them to pass over the edge of the mouth-piece, and then spring inward to retain the holder thereon. The main portion 6 of the holder is countersunk and cut out to form apertures 7. The inner edge of said main portion around the central aperture through the holder is formed with rearwardly extending inner fingers 8, which, at their rear ends, are turned outwardly, as shown at 9. The solid disinfectant material is annular in form and rests against the rear surface of said main portion 6 of the holder,

and is contained between said surface and the inner surface of the telephone mouthpiece, although not necessarily in contact with the latter. Said annular material 3 is retained in place by the fingers 8, which engage the inner surface of the material, while their outwardly extending ends engage the inner portion of the rear surface of said material. To secure the disinfectant material in place, the fingers are pressed toward one another until their outwardly bent ends can pass through the central hole in the disinfectant material, and then spring, or are pressed, outwardly again.

The advantages of the device are that it is made from a single piece of metal, and by a cutting and stamping machine; that a large extent of surface of the antiseptic material is exposed; and that the operations of securing the antiseptic material in place in the holder and securing the holder upon the telephone mouthpiece are very simple, and therefore the antiseptic material can readily be renewed when necessary.

I claim Means for maintaining a mouthpiece anti-v septic comprising a ring of antiseptic material and an annular sheet metal holder securing said ring within the mouthpiece, having means engaging the front portion of the mouthpiece to hold it in place, the inner edge of the holder having rearwardly and outwardly extending fingers engaging the inner surface of the ring to hold the ring in position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing; witnesses.

IRVING S. ROSENBLATT.
