Application July 8, 1941, Serial No. 401,517

Claims. (Cl. 179-185) My invention relates to new and useful improvements in telephone attachments, and more particularly to a sanitary device therefor, the primary object being to provide an attachment which may be applied readily to the mouth-piece or transmitter of either the wall type or French type telephones to insure cleanliness and avoid transmission of germs.

Various devices have been suggested from time to time for the purpose of presenting a sanitary mouth-piece for telephones, but due to the complicated construction thereof, cost of manufacture and possible interference with telephone communications, the same have not been adopted. My invention contemplates a simple and durable device which may be quickly and readily applied or removed, one which is simple and inexpensive to manufacture and which will not in any sense whatsoever interfere with or conflict with transmission of messages.

A further object of the invention resides in the provision of a device carrying a roll of sanitary paper capable of being drawn across the transmitter at will and torn, and then destroyed.

A still further object resides in the provision of a flexible element removably attached to the paper support and adapted to be resiliently and removably engaged with the mouth-piece or transmitter of the telephone.

A further object of the invention resides in constructing a support for the roll of paper which will enable the latter to be readily drawn across a plane forward of the transmitter and. torn from the support without effort.

A still further object resides in providing a device of the character described which is simple and durable in construction, inexpensive to manufacture and one which will be very efiicient in use.

With these and numerous other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing, forming a part of this application,

Figure l is a side elevation of a telephone of the French type showing my sanitary attachment in place thereon;

Figure 2 is a plan view thereof;

Figure 3 is a side elevation of the receiver shown on an enlarged scale with my improved attachment applied to the transmitter;

Figure 4 is a transverse vertical section taken on the line 4-4 of Figure 5, with parts in elevation;

Figure 5 is a central vertical longitudinal section taken on the line 5-5 of Figure 4, with the receiver shown in elevation;

Figure 6 is a front face view of the attachment removed, and

Figure 7 is a rear face view thereof.

In describing the invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views, and in which the numeral l designated a telephone instrument of the French type, wherein the receiver 2 thereof has the ear piece 3 at one end and the mouth-piece or'transmitter 4 at the opposite end. While I have shown my attachment as applied and particularly applicable to the mouth-piece of this type of telephone instrument, it will be understood, of course, that it may be applied to transmitters, or mouthpieces of other types of phone instruments.

Carriers of various diseases transmit the germs through the mouth and it has been discovered that telephone instruments aid and abet in the transmission of such germs. It is the purpose of my invention to provide a device, simple in construction, and inexpensive to maintain, which may be readily attached to the mouth-piece to present at all times a clean and sanitary locality on the telephone, against whichor adjacent to which the mouth of the speaker may be placed.

My attachment generally comprises a support 5 of plate-like formation carrying a roll 8 of sanitary paper or the like, and a removable or detachable means I for resiliently and removably engaging the support with the mouth-piece of the telephone. The plate 5 has one end thereof formed into a partial housing, the latter being designated by the numeral 8. This is accomplished by forming at one end of the plate an up standing wall 9 and side walls l0. Applied thereover is a top member I I having side walls [2 and a front wall l3. This housing supports a shaft I4 on which the roll of paper 6 is mounted, as clearly shown in Figure 5 of the drawing. As seen in Figures 6 and 7, the shaft M has an angular end and a pin passing through the opposite end so as to retain the 'same in place, but obviously the pin may be readily removed and a new roll of paper inserted when necessary.

The paper from the roll 6, as clearly shown in Figures 5 and 6 of the drawing, is guided through a slot I5 in the bottom of the housing 8 and extends over the front face of the plate 5, being guided in position thereover by the bent ears l6 formed integral with the side edges of said plate 5. After extending for the greater length of the plate 5, the paper is guided through a second slot I! formed transversely of the plate adjacent the end thereof opposite that supporting the housing 8, and the paper is adapted to extend to a point beyond the free edge [8 of the plate or support 5. That portion of the plate between the free edge l8 and the slot I! is depressed from the front face thereof as shown at l9 to provide hemispherical projection on the rear face of the plate. These projections have a tendency to force the free end of the web of paper extended through the slot l7 away from the plate 5, as clearly shown in Figure 5, so that the paper may be drawn across the plate from the roll without effort.

The central portion of the plate is perforated, as shown at 20, so that no serious obstruction occurs at the point where the voice passes to the transmitter. The plate is also struck-up from a plurality of positions surrounding the perforations 20 to form the angular bent ears 2|. These ear-s constitute engaging and supporting means for the transmitter engaging means I.

The transmitter engaging means I may be of any desired shape but is preferably hemispherical and formed of rubber, synthetic rubber, metal or plastic resilient material. I do not wish to be limited as to the character of material to be used in constructing this means, although I have found rubber to be cheap and effective. An opening is formed at the end of this hemispherical member 1 whereby the same may be resiliently snapped in place on the angularly bent ears 2i of the plate 5. This member 1 may be readily and snugly engaged with the mouthpiece or transmitter 4 of the telephone, and in order to aid and assist in the retention of this means on the mouth-piece, the curved arms 22 may be provided on the member I by integral or other connection. Thus the transmitter engaging means may be readily applied, with the plate thereon so that the paper from the roll 6 will cover the front of the transmitter. This paper may be drawn from the roll at will, torn 01f and destroyed, so that each user of the instrument will have a clean and sanitary location adjacent to which his mouth may be placed. If desired, the paper may be used also as a memorandum sheet, and that portion of the plate 5 between the slot [5 and the ears 2| may be used as a backer or support for the paper when writing thereon.

From the foregoing description of the construction of my improved invention, it will be seen that I have provided a simple, inexpensive and eflicient means for carrying out the various objects of the invention.

While I have particularly described the ele-' ments best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, without departing from the spirit or sacrificing any ofthe principles of the invention.

Having thus described my invention, what I claim is:
