IPROPHYLAGTIC DEVICE FOR TELEPHONE APPARATUS Application filed April 21,
This invention relates to telephone apparatus, and has for its object to provide a prophylactic device adapted to be attached to a telephone transmitter, in order to avoid the direct contact of the speakers mouth with the transmitter mouth-piece. This is accomplished by means of the interposition of a sheet of sterilized paper between the mouth of the speaker and the telephone transmitter. In
this way the spread of disease infection is prevented.
Another object of the invention is to provide means for unrolling successive sheets of sterilized paper as the telephone is used.
ing drawings, in which: I
Figure 1 is a front elevational view of the device attached to a telephone.
Fig. 2 is a partial side elevation of the same.
Fig. 8 is a detail elevation of the device. Fig. 4 is a perspective detail ofthe same.
Fig. 5 is a perspective detail view of the paper roll. a
In the drawings, 1 indicates the transmitter and 2 the receiver for a telephone apparatus 3 of the common type. To the mouthpiece 4 of the transmitter is attached a metallic frame of wire or metal sheet, shaped as shown in Figs. 3 and 4. This frame comprises two parts which are symmetrical on both sides of the axial line of the device. Said parts comprise opposed central semicircular portions 5 and 6 which extend respectively at one end in divergent supporting arms 7 and 8, which respectively terminate in angular elbows 9,-10, said elbows terminating in aligned opposed pivot pins 11, 12. Diverging supporting arms 13, 14 extend from the other ends of the portions 5, 6 and are integral with an oblong rectangular frame 15 which is at right angles to the first named frame. The frame first named is elastic and may be readily attached to the transmitter mouth-piece 4 by engaging the parts 5, 6 around the same, as will be understood, at a'point between the shoulder of the mouth-piece and the flange 16 thereof.
. The pivot-pins 11. and 12 are provided with The invention is shown in the accompanyits free end may by its resiliency rest against 7 the roll 19. 5
tachably mounted on said pins, said paper being preferably thin and of an antiseptic quality. The frame 1 5 is of such length that its outer end projects beyond the mouth-piece ,4 when the deviceis in placethereon.
Under the central portion of the frame 15 is rigidly mounted a small plate 20 having a flange rovided with saw-teeth21 forming a cutter or the paper sheet 19 which is passed around the outer end of the frame 15 and then between the small plate 20 and a spring tongue 22 which is attached atone end to" the outer end of the frame 15 and which grips and holds the end of the paper in place.
I The paper-roll19 is preventedj'fromnnrolling by means or a spring sheet 28 welded at an end to one of the. divergent supporting arms 8 and is directed upwardly, so that It will be readily understood that to mount the device in'place, the mouth-piece 4 must be unscrewed and'the frameplaced so that the central portions 5-and {6 overlap the threaded flange -16..usuall supporting the mouth-piece, and the mouth-piece must thenbe screwed on said flange 16 until the central portions 5 and 6 of the frame press against said flange 16. i
In the use of the telephone apparatus to which this device is adapted to be attached, whenever a person has finished his conver' sation, and another person is to speak, the latter should change that part of the paper sheet 19 covering the mouth-piece 4, and through which part the voice is transmitted, by unrolling a suitable length of the paper sheet 19 and sliding the same across the frame, and cutting the remaining portion formerly used, by means of the knife 21, as indicated in dotted lines in Fig. 2 of the drawings.
What I claim is:
1. A prophylactic device for telephone apparatus, comprising a metallic frame divided in two parts of symmetrical shape at both sides of the axial lineof the frame and which parts are capable of yielding to and from each other, the central portions of the frame forming a circular opening through which said central portions are adapted to set between the mouth-piece and the threaded flange of the telephone apparatus holding said mouth-piece, spaced and aligned pivot- 5 pins provided at an end of the frame, a roll.
of paper detachably mounted on said pivotpins, a frame carried on the other end of the first frame and in a plan forming a right angle with the plan of the first frame to 1 serve as a guide for the unrolled sheet of paper so that this may remain lain out beore the transmitter mouth-piece, and means connected with the second frame for cutting the sheet of paper.
2. A prophylactic device for telephone apparatus, comprising a metallic frame divided in two parts of symmetrical shape at both sides of the axial line of the frame and which parts are capable of yielding to and from each other, the central portions of the frame forming a circular openin through which said central portions are adapted to set between the mouth-piece and the threaded flangeaof the telephone apparatus holding said mouth-piece, spaced and aligned pivotpins provided at an end of the frame, a roll of aseptic paper detachably mounted on said aligned pivot-pins, a frame carried at the other end of the first frame to serve as a guide for the unrolled sheet of paper so that it may remain lain out before the transmitter mouthpiece, a spring sheet connected to the first rame and which by its free end may rest against the endless roll of paper, a plate bent "in right angle and rigidly connected to the central portion of the second frame and whose free portion shows its edge provided with sharpened teeth, and a spring sheet con nected to the second frame and which by its free end holds the sheet of paper resting against the sharp-edge plate.
In witness whereof I aflix my signature.
