HERMANN JANKELOWITZ, OF GERA, GERMANY.
AN'IISEPTIC LINING F TALKING AND HEARING TUBES FOR TELEPHONES.
Specification of Letters Patent.
Patented. May 12, 1908.
Application filed may 26, 1907. Serial No. 375,759.
To all wi'wm it concern:
Be it known thnt I HERMANN JANKELD- Wrrz, a subject of the vmperor of Germany,
the linings residing at Gere, (Reuss,) Germany, have invented certain new and useful i111 provements in Antiseptic Lining of Talking and Hearing Tubes for Telephonesot which the following is a full clear, and exact specifics- "tion.
In order to avoid the transfer of germs in telephone IO("iVl'S and transmitters, they are lined according to the present invention With antiseptic paper or similar nntteriol consisting either of single sheets or of on end-- les ribbon rolled up in a. spiral. These sheets are each provided with suitable per foretions to facilitate the separation from the pad and on one side a. projection or ear is provided by which the individual sheet may be torn out. Besides this enrpieceothcr pro joctions are provided serving to secure the sheets to the mouth piece or opening of the transmitter or receiver respectively. A per son using the telephone can therciore easily pull out the uppermost sheet of the lining and contagion from persons having used the telephone before, is prevented.
'lhe drmving illustrates the invention in two embodiments. I
Figured is a. front view of o. niouth piece of a transmitter lined according to the present invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is it blank SlltEttlIOlll which maid-e. Fig. 4- shows the lining of said mouth piece mode of a spiral strip of paper. Fig. 5 is a front Vli'W of :1 receiver, Fig. 6 21 section, and Fig. 7 iilustretes the lining for a. receiver mode of it lorg strip oi paper.
The lining consists of a. nun'ibcr of superposed sheets of antiseptic paper a, crimped together in such it manner that they it into the mouth piece or before the receiver. Flat sheets as shown in Figs. 1, 2, 3, 5 and 6 may be used orlong strips (l as shown in Figs. 4 and 7; In both cases the sheets are provided with projections or flaps b and c and the flops b are used to secure the sheets upon the receivers and transmitters, While the hips c are preferably used to seize the individual sheets and tear them out. A number of sheets Fig. 3 are superposed so that the flaps b and c register, the middle part is then out out and the sheets are pressed into the con icnl opening of a transmitter and the paper is criinped and folded until the lining smoothly covers the inner surface of the mouth piece.
The outer edges of the sheets are folded and smoothed around the outer edge of the mouth piece is shown in Fig. 2 and the flops b are turned back upon the exterior of the mouth piece where they may be held in position by on convenient means for instance strings or twincs, nails or screws, to which end the ilnps may be perforated as shown in Figs. 1 and 5, or even glue can be used to hold the flaps down in position. The flaps c are left to stand out radially so that they can be gripped easily when itis desired to tear out the uppermost sheet oi the lining. Inorder to facilitate this manipulation the flaps b are preferably provided with perforations along the line of joint to the nniin sheet as shown in Figs. 1 end 5. The lining of the receivers is ellcctei'l in the some manner only the crimping of the paper is much slighter than the crimping into the transmitters which will be easily understood. The crimping at the edges for transmitters or receivers is nbout the some.
/Yhen long strips are used for the lining like those marked (l in Figs. 4 and 7, the strip is first rolled up in o spiral, so that the flaps b and r utthe edges overhl 'l each other, then the pnper is secured upon the receiver and trnnsniiitin' in the some way as above described. To facilitate the separation of the single coverings it is preferable to use ridditionul p n-hrrotions transversely to the paper bond as shown in Figs. 4' and 7, end in the letter form peri'orntions.mziy be used also nlong the edge as shown.
tors end receivers consisting of a plurality of superposed sheets of antiseptic paper rolled up from a long strip with lateral projections registering with each other, substantially as described. 1
In testimony whereof I niiix my si nature.
