ANTISEPTIC TELEPHONE-MOUTHPIECE.
SPECIFICATION forming part of Letters Patent No. 754,646, dated March 15, 1904.
Application filed April 27, 1903. Serial No. 154,426. (No model.)
effective in operation.
Our invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a longitudinal section of our improved apparatus, part thereof being broken away to show the construction. Fig. 2 is a cross-section thereof. Fig. 3 is a perspective view of the screen-holder detached. Fig. 4 is a rear view of the same. Fig. 5 is a longitudinal section of a modified form of the invention.
Referring to the drawings, 1 represents a bell-shaped shell, open from end to end for the passage of sound, and 2 represents a cup having its lower portion 3 detachably secured, as in Figs. 1 and 2, or fixedly secured, as in Fig. 5. Said cup is adapted to contain an antiseptic substance, and its peripheral edge is attached directly to the under side of the shell. Said shell has in the modification shown in Figs. 1 and 2 a number of perforations 4: within the peripheral edge of the cup 2, but is imperforate except, of course, the open ends outside said edge. In Fig. 5 it is completely open within the edge of the cup, but imperforate outside said cup.
In the modification shown in Figs. 1 and 2 the mouth of the cup flares both longitudinally, as shown at 5 in Fig. 1, and transversely, as shown at 6 in Fig. 2, so that it underlies substantially the Whole width and length of the shell. Hence the antiseptic vapor, in rising from the antiseptic liquid placed in the cup 2, effectually fills the mouthpiece and destroys the germs. An important advantage of this flaring shape is that any mucous or sputum will readily find its way into the cup.
In the first modification the lower part of the cup is detached and the antiseptic substance placed therein. In the second modification the antiseptic substance is placed in the cup from the top and a wire screen 10 is sprung into place below a circular shoulder 11. Small apertures 18 admit air to allow of a free current for the gas.
An advantage arises from the construction of limiting the perforations4 to the part of the shell immediately above the cup. For the transmission of sound it is desirable that the inner surface of the mouthpiece shall be smooth. This smoothness is thus interfered with as little as possible, while not detracting from the antiseptic properties of the mouthpiece, for it is only through the holes above the cup that the antiseptic vapor passes, and these holes extend substantially the whole width of the mouthpiece. A further advantage of this construction is that every part of the device can be easilyreached and cleaned with a brush or cloth.
We claim 1. An antiseptic telephone-mouthpiece comprising a single bell-shaped shell unobstructed in the interior, and a cup for an antiseptic substance, lying wholly beneath the shell and substantially its whole width, the entire peripheral edge of which is attached directly to the under side of said shell, said shell being perforated within, but imperforate outside, said edge, substantially as described.
2. Anantiseptic telephone-mouthpiece comprising a single bell-shaped shell unobstructed in the interior, and a cup for an antiseptic substance lying wholly beneath the shell and substantially its whole width, the entire pehands in the presence of two subscribing witnesses.
