ALVAN P. LEVI, HYMEN SCHLESSINGER, AND MAURICE SCHLESSINGER, OF SAN FRANCISCO, CALIFORNIA.

Specification of Letters Patent.

Patented Oct. 4, 1910.

Application filed May 12, 1909. Serial No. 495,435.

To all whom it may concern:

Be it known that we, ALvAN P. LEVI, HY- MEN ScHLnssINGER, and MAURICE SoI-iLnss- INGER, all citizens of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Telephone- Mouthpiece Attachments, of which the following is a specification.

()ur invention relates to antiseptic attachments for telephone mouthpieces.

The object is to provide a simple, cheap, practical, neat-looking attachment for an ordinary hard rubber telephone mouthpiece,

i. which is adapted to contain a suitable, disinfecting medium, which while producing the desired antiseptic qualities will in nowise interfere with the ordinary use of the telephone; which device will appear to be a part of the telephone and practically be unnoticed, and also, which device is so arranged that it can be readily re-charged at frequent intervals.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a central section. Fig. 2 is a side elevation partly broken away.

A represents the usual telephone transmitter, and 2 the common bell-shaped mouthpiece which is usually adapted to screw into the transmitter.

Our invention comprises an attachment 3 of suitable size, shape and material detachably fitting the outside of the mouthpiece and containing a filling of suitable absorbent material, as sponge, felt, cotton, or the like, represented at 4; this attachment being held in place simply by screwing the mouthpiece on to the telephone. Preferably this attachment is spun from a piece of sheetmetal, and is bell-shaped and open at the ends, with inwardly turned end flanges 5-6 forming, with the outside of the mouth piece, an inclosing chamber to retain the absorptive material 4. The walls of the telephone mouthpiece are perforated at suitable intervals, as represented at 7, to allow the exhalation of the disinfectant medium contained in the chamber within the attachment 3 to pass into the interior of the telephone mouthpiece in the desired manner.

The device is extremely simple, and cheap to manufacture and to maintain; and by simply unscrewing the mouthpiece from the telephone, the device can be taken off the mouthpiece and the absorptive material recharged with a suitable disinfectant, and the device again put on to the mouthpiece and the mouthpiece fixed to the telephone again ready for use.

Having thus described our invention, what we claim and desire to secure by Letters Patent is- An improved attachment for telephone mouth-piece, said attachment consisting of a substantially bell-shaped member open at both ends and adapted to be slipped on to the mouth-piece from the rear, and having a free telescoping movement with the mouthpiece, said attachment having inwardly turned flanges at both ends forming an in termediate chamber which extends substantially the major length of the mouthpiece, the outer wall of the attachment being substantially parallel and flared symmetrically with the mouth-piece, and an absorbent material in said chamber carrying a disinfecting medium and producing a skin friction sufficient to hold the attachment on the mouth-piece, said mouth piece having perforations communicating with the absorbent material.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
