'ANTISEPTIC MOUTHPIECE FOR TELEPHONES.
SPECIFICATION forming part of Letters .Patent No. 529,609, dated November 20, 1894.
Application led April 25, 1894- To @ZZ whom it may concern:
Be it known that we, RIAL N. DENIsoN and FRANK M. GEARY, of Brooklyn, in the county of Kings and State of NewYork,haveinvented a new and Improved Antiseptic Mouthpiece for Telephones or Speaking-Tubes, of which the following is a full,.clear, and exact description.
Our invention relates to an antiseptic mouthpiece for telephones land speaking tubes, capable of attachment to any telephone or to any speaking tube, and not materially differing in general appearance from the ordinary mouthpiece.
A further object of the invention is to provide a mouthpiece which will be cleanly,and in no manner a conductor of germs, and one which may be durably, simply and economically constructed.
rlheinvention consistsin the novelconstruction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the views.
Figure 1 is a longitudinal vertical section through the improved mouth piece, illustrating it as applied to a telephone; and Fig. 2 is a front elevation thereof.
The mouth piece consists of two shells, an inner shell A and an outer shell B. These two shells are spaced a predetermined distance apart, forming a chamber C, and the shells are made to meet at their outer ends,
or the outer end of the chamber C is otherwise closed; and the inner end of the charnber is likewise closed 'ordinarily bythe two shells being brought into engagement at that point. Either the inner or the outer shell, preferably the inner shell, is provided with a neck D, eXteriorly threaded in order that it may be screwed into the opening in a telephone overthe diaphragm; but the nfouthpiece may be otherwise applied if in practice it is found desirable, and when the mouth- Serial No. 508,961. (No model.)
piece is. used in connection with speaking tubes, the neckD is usually made longer than illustrated, and with a smooth exterior, but 5o the exterior may be roughened if found necessary.
The chamber Ois adapted to contain an antiseptic material E, of any desired character. The said antiseptic material may be in the form of a paper, or it may be in the form of a liquid, in which latter event as shown in Fig. 1, the chamber is'made to contain felt or other absorbent material, made to closely hug theexterior of the inner shell, the said ab- 6o sorbent material being satu rated with or having applied thereto a liquid absorbent.
The speaker using the tube is given the benefit of the absorbent material employed, by producing in the inner shell A a series of apertures F, through which the odor from the absorbent material may readily escape. Preferably the apertures are grouped together quite closely, and extend practically over the entire inner face of the inner shell. manner the air may pass through sundry of the apertures, become impregnated with the antiseptic material, and escape through others of theapertures into the interior of the mouthpiece.
Having thus described our invention, we claim-'as new and desire to secure by Letters Patent- 1. A mouthpiece for telephones and speaking tubes, 'containing an antiseptic material 8o and provided with vents leading from the material to the interior of the mouthpiece, substantiall y as shown and described.
2. A mouthpiece, the same consisting of an inner and an outer shell united to form an intervening chamber, the inner shell being perforated, and an antiseptic materiallocated within said chamber, as and for the purpose set forth.`
