GERHARDT E. ennui, or PHILADELPHIA, PENNSYLVANIA.

GUARD;FOR THE noucrrreinons or TIELEPHONE-TRANSMIT'IERS'.

To all whom 'it may concern:

Be it known that I, GERHARDT E. GRIMM, a citizen of the United States, residing at Philadelphia, in the mouth-piece, as well as to destroy such germssand prevent the possible spread of disease.

The primary object of the invention is to provide guard of the character mentioned, which is simple in construction, inexpensive of production, and which will effectually attain the purposes for which it is devised.

A further object of the invention is to provide a guard which will embody in its construction improved and simplified means for supportinga web of antisep; tic material in position to have a portion thereof disposed across the mouth-piece of the transmitter, and

which will permit saidportion to be removed when deemed necessary and replaced by a fresh or new portion' A further purpose of the invention is to provide a novel construction of package, roll or film of antiseptically treated material adapted for use in connection with a suitable web orfilrn holder, such for instance,

as the holder herein sh vn and described.

A still further purp is to construct an antiseptically treated web or film in roll form, with calendar indicationson its face, so spaced as to be successively brought to view through-*the talking opening in the holder provided therefoi fwhereby to provide a simple and convenient calendar and combined telephone guard. v

The invention has in view other more or less important objects, which willbeclearly set forth in the following detailed description.

Briefly and generally stated the invention comprises in part, a web or film holder, consisting of superposed plates or leaves having registering openings and an attached roll holding housing at one end, and means for attaching the holder to the mouth-piece of a telephone transmitter.

Thei'invention further comprises a novel construction of'web or film package, consisting of a slotted tube having closed orsealed ends and a flap for covering and closing the slot in the tube.

Specification of tater; Patent. Application filed May 26,l90 6. Serial n. 313,355.

Patented July 16, 1907.

Further, the invention comprises the features of construction and arrangement of parts hereinafter set-- forth in detail and then defined in the appended claims.

In the annexed drawing, which is illustrative ofthe preferred embodiment of the invention, Figure 1 is a perspective view of one of my improved telephone guards shown attached for use on a telephone transmitter; Fig. 2 is an end view of the same: Fig. 3 is a perspective view of the holder looking at the rear side thereof and showing the means for attaching the same to a transmitter; Fig. 4 is a view similar to Fig.

showing a slightly modified construction: Fig. 5 iisa perspective view. partly broken away, of the web or film package and roll, the web or film being partially withdrawn; Fig. 6 is a transverse sectional view of the holder shown applied to atransmitter mouthpiece: and Fig. 7 is a central longitudii'ial section of a holder having the roll-housing offset rcarwardlv from the plane of the holder plates or leaves.

- In the preferred form of the invention, as illustrated in Figs. 1, 2 and 3 of the drawing. the holder: or guard consists of a sheet of card-board, celluloid, metal or other suitable material. bent intermediate its ends to provide a cylindrical housing 1, at one end of the holder, the two end portions or leaves 2 and 3 being brought together or superposed as shown, to provide between them aspa'c e to receive the antiscptically treated web or film presently to be described. Each of the leaves 2 and 3 is provided with an opening 4, which openings register with each other when the leaves are superposed,'and also register with the opening in the transmitter. mouth-piece 5, as shown more clearly in Figs. 6 and 7, when the holder is in position for use.

The rear leaf 3, in the form of invention shown in Fig. 3, is further provided with suitable means for detachably engaging the mouth-piece 5 of the transmitter to suppprt the holder in position for us This engaging or attaching means consists of oppositely disposed arms, or iwings 6, 7, which may be formed integral with the-leaf 3, said wings or arms 6, 7, being bent or folded rearwardly on there-a1 face of theleaf 3, with their unattached ends free and extending toward each'other, as shown. In placing the coinplete guard in position on the mouth-piece 5 of the transmitter, the arms 6, 7 are arranged to resiliently engage and grasp the said mouth-piece and serve to frictionally hold the latter at diametrically opposite points thereon. in order to prtfvide f1 r a m re secure and effective engagement of the wings withthc transmitter, the vcrti 11 free edge of each wing is formed with a curved ret S in which a portion of the mouthpiece is reccived. and which curved portions engage the circular mouth-picce and afford a more satisfactory engagement than if said vertical engalging iaces'were straight. The wings 6, 7 are permanently secured to the leaf 3, sons to provide a practically integral structure. v 7

The means for securing the wings to the leaf 3 con sists of wire staple fasteners 9 of well known form, which are located closely adjacent the vertical edges of the leaf 3, the prongs of said staples passing through the said wings and leaf so that not only are the wings permanently secured at their bases, but are anchored to the leaf 3 at apointremoved from their free or recessed edges, whereby. great rigidity and grasping strength is given to said wings. so that they form elastic or spring mouth-piece engaging clips to hold the guard more effectively in position. While I have shown the wings secured by wire staples, as affording a simple and efficient means for this purpose, it is obvious that other means may be employed if desired, without departing frorn'the spirit of the invention.

Instead of forming the wings 6, 7, integral with the rear leaf 3, I may. if desired, form these wings integral with a supplemental plate 10, as shown in Fig. 4, which plate, with the attached wings, may then be secured to thc'rear' face of the leaf 3. This construction gives additional strength and rigidity to the leaf 3, and is especially desirable in constructions where the holder is formed of cardboard.

In order to hold the leaves 2, 3, in facial contact, and the cylindrical housing 1 in proper position to receive the film package or roll, presently to be described, I provide the opposite edges of'the leaves 2 and 3 with notches or recesses 12, said notches or recesses being adapted to receive and retain endless, elastic bands 13, which are stretched over and around the l aves of the guard as clearly shown. The notches or recesses 12 are preferably located at the base of the cylindrical housing 1, and free end of the leaves, re-.

'spectively. The endless elastic bands may be readily removed and replaced, as desired, in order to facilitate the operation of supplying a new film or web roll.

The film roll or package, which constitutes one of the features of this invention, consists of a paper tubal 4ghaving a. longitudinal slit 15,- and plugged or-sealed ends 16. The ends of the tube-may be closed in any preferred manner'but in the arrangement shown, sin.- ple plugs or stoppers are employed, which, after-the roll or film is in position, may be closed and hermetically sealed. The tube 14 has an attached flap 17, the free end of which is adapted to close the longitudinal slot 15, whereby to maintain the roll or film 18 of antiseptically treated material, in a perfectly clean and sanitary condition when packed or stored. This fiap 17 also serves to prevent endwise movement of the tube when the latter is placed in position in the cylindrical housing 1, this result being accomplished by reason of the fact that the flap extends down between the two leaves 2, 3,'and below the point where the. uppermost elastic band surrounds the leaves, all as more clearly shown in Figs. 2 and 7 of the drawing.

The roll or film of antiseptically treated material 18 is in the form of a thin web or sheet of tissue paper treated with any suitable antiseptic composition. In order to combine with this web a ready and convenient calendar and also provide a means to indicate to the user of the telephone whether a fresh portion of the providing a ready calendar.

at proper distances apart, indications correspondii'ig to the calendar months and days, these indications being so separated or spaced apart as to be brought successivley into view over the openings in the leaves. By preference, the antiseptically treated web or film is transversely scored or weakened, at the points between the before mentioned calendar indications, although these scorings may be omitted if desired, it being understood that the lower edge 19 of the leaves 2, 3, provide a tearing edge for the web or film whereby to permit an easy separation thereof, as it is withdrawn from the roll. Instead of providing=the web or film with calendar indications, I 'may. printther'eon any other suitable mark or character, as for instance a red cross; ,or the web or film may be provided with suitable advertising matter, as desired. I consider that the provision of aweb or film of this character, with calendar indications thereon, to be an important feature of the invention, because it thus-practically insures the bringing of a clean film surface over the openings of the blank each and every day of the year, thus making the device more sanitary, and at the same time In Figs. 1, 2, 3 and 4 the cylindiical housing 1 is shown as disposed above and in line with the leaves 2, 3. If desired, this housing may be offset to one side of the plane of the leaves, as in Fig; 7. This construction somewhat reduces the size of the exposed face of the guard, rendering it more sightly; and, furthermore, the web or film being compelled to travel,-during intermediate its ends to provide a cylindrical housing at One end of the guard. the leaves of the strip or plate havi g registering openings. and means for securing the guard in place on the mouth-piece of a transmitter.
