, JOHN MOCAUSLAND, OF PROVIDENCE, RHODE ISLAND.

SANITARY TELEPtIONE-MOUTHPIECE.

Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed May 8, 1912. Serial No. 695,810.

To all whom it may concern Be it known that I, JOHN MCCAUSLAND,

' a citizen of theUnited States, residing at the city of Providence, in the-county of Providence and State of Rhode Island,.have invented certain new and useful Improvements in Sanitary Telephone-Mouthpieces, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to a sanitary readily'detachable transmitter mouthpiece, and has for its object to provide a telephone transmitter coneshaped mouthpiece made of paper or other readily destructihle material to be readily removed from the transmitter casing and destroyed after using to be replaced by a fresh one.

A further object'is to provide a wire bracket or yoke to be readily attached to any transmitter casing, said"bracket being adapted toreadily detachably support a transmitter mouthpiece so that mouthpiece cones may be provided of such inexpensive material and construction that they may be removed and destroyed after each person has used the telephone to prevent the spread of contagious diseases through a continued use of a single mouthpiece.

Vith these andother objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is a side elevation showing my improved device attached to a telephone transmitter casing. Fig. 2 is a detail in perspectiveshowing the diaphragm protecting plug. Fig. 3, is a detail in perspective illustrating my improved cone-supporting bracket. Fig. 4 is a detail in perspective of my improved paper mouthpiece cone. Fig. 5 is a modification showing a clip or clamp for releasably securing the cone to the protector plug. Fig. 6 is another modificat-ion showing an internally screw-threaded collar into which the cone may be removably secured. I

Referring to the drawing, 1 designates the ordinary transmitter box or casing, and 2 the diaphragm protector plug which has a threaded body portion 3 adapted to be screwed into the front plate of said casing- My improved cone-supporting bracket is preferahlv constructed of wire having arms i t adapted to extend up around the barrel port-ion 3 of the plug and having forwardly extending portions 5 with upwardly extending arms 6, which arms'are bent back upon themselves forming a U-shaped slightly resilient yoke 7 for the reception of the cone-shaped mouthpiece 8. This mouthpiece, as illustrated in Figs. 1 and i.

is provided on its outer surface near its inner end with an annular groove 9'for the reception of the yoke portion of said bracket.

One of the essential features of myimproved device is that this mouthpiece is a plain hollow truncated cone constructed of paper or fiber, or other inexpensive readily destructible material, the shape being such that it can be made froni paper at. so little expense that one can afford to use a fresh cone each time the telephone is used, or particularly after having been used by :ll\-' other person. Such a device would heof great service particularly in public telephone stations to prevent the spread of contagious diseases, which often results from the use ofa common mouthpiece permanently attached.

In applying my improved deviceto any telephone it is only necessary to remove the usual permanent mouthpiece, pass the body of the diaphragm protecting .plug through between the arms 4 of the bracket and screw the plug into the casing thereby binding the bracket to the casing and supporting the forwardly extending U shaped yoke portion just in front of the plug to receive the mouthpiece. In applying the mouthpiece itself to this yoke it is only necessary to pass the annular grooved portion down between the arms of said yoke which securely holds the mouthpiece in proper position. from which it may be readily lifted off when desired.

The modification illustrated, in Fig. 3 shows a clip 10 permanently attached to the plug 2 and having a biting jaw 11 which is adapted to engage one end of the mouthpiece to bite and secure it in position. That illustrated in Fig. 6 shows an internally threaded collar 12 attached to the plug 2 into which the cone may be secured by sim-
