Application filed December 11, 1919. Serial No. 344,207.
mitter-Mouthpieces, of whiohthe following is a specification.
The purpose of the invention is to pro vide the mouth-piece of a telephone transmitter with a sanitary surface formed of such material as to sterilize any germ that may be deposited on the mouth-piece.
The invention is illustrated in the accompanying drawing wherein a telephone transmitter is shown in elevation, the mouth-piece being in section.
1 marks the transmitter and 2 the usual mouth-piece.
I form a detachable cover 3 for the interior surface of the mouth-piece. made up of a disinfecting material, I have found that naphthalene is desirable for this purpose as this has the sterilizing quality and is susceptible of being molded to the proper shape. I prefer to provide a backing i for this covering 3 of metal and as the covering 3 is formed the metal forms one part of the mold and the sterilizing material adheres to it. v
The cover is so shaped as to make a close fit with the inner surface of the mouth-piece and is detachably secured therein by an annular clip 5 having a spring lip 6 which snaps over the outer periphery of the mouth-piece andholds the sterilizing cover 3 in place with a spring-pressed pressure so that there is no interference with the efiiciency of the mouth-piece in the transmission of messages through the transmitter.
What I claim as new is I 1. A sanitary cover for transmitter. mouth pieces comprising a covering formed of sterilizing material and conforming in general contour to the interior surface of the mouthpiece, said covering being separately formed and detachable from the mouth-piece; and an annular ring arranged on the periphery of the mouth-piece forsecuring the cover in place, said ring engaging only the outer edge of the cover whereby the greater portion of the sanitary covering may be exposed.
2. A sanitary cover for transmitter mouthpieces comprisinga covering formed of sterilizing material and conforming in general contour to the interior surface of the mouthpiece, said covering being separately formed and detachable from the mouth-piece; and an annular clip having a spring lip engag- OFFICE.
ing the periphery of the mouth piece and securing the covering in the mouth-piece with a spring-pressed engagement, said clip engaging only the outer portion of the covering. whereby the greater portion of said covering is exposed. I
In testlmony whereof I have hereunto set my hand.
SIDNEY FLACK.
