HYGIENIC APPLIANCE FOR SOUND-TRANSMITTERS.

SPECIFICATION forming part of Letters Patent No. 768,768, dated August 30, 1904. Application filed January 24, 1902. Serial No. 91,119. (No model.)

for Sound-Transmitters, of which the follow-v ing is a specification.

This invention relates to improvements upon hygienic appliances for soundtransmitter mouthpieces, for which Letters Patent of the United States, No. 654,096, were granted to me July 17, 1900.

Some of the objects of the present invention are to provide superior and simpler means for holding the hygienic stripvtaut across the mouth of the sound-transmitter, to increase the facility of applying said strip to the stripholder ready for use, to avoid any liability of tearing or fraying the edges of the strip, and to reduce to a minimum the contact between the holder and that face of the strip which is presented to the user.

A further object is cheapness, simplicity, and increased ease of manufacture.

In the present appliance the holder for the axle upon which the roll of the hygienic strip is carried comprises two/resilient standards having holes, respectively, in whichY the ends of the axle are'journaled. Said standards are preferably bowed toward each other, so that the portion around the axle-bearing will frictionally contact with and press against the ends of the-roll, thereby to act as a brake to hold the same against racing. Provision is upon the roll is uniform at all times.

Another feature oi' the invention consists.

in the construction of a member of' the stripholder, which is bentto form three walls of the tension-guide for the strip as well as a seat for the member which forms the other .wall of the strip-guide and cutter, across the edge of which the strip is to be drawn to tear oft' the used portion thereof from time to time, as required.

The accompanying drawings illustrate this invention.

Figure I is a perspective view of the -im- -in position ready for use as it appears 'after a used portion has been torn oif. Fig. III is a side elevation of the appliance detached. Fig. IV is a vertical mid-section on line IV IV, Fig. II. Fig. V'is a fragmental section `on line V V, Figs. III and IV. Fig. VI is an exaggerated plan section on line VI VI, Figs. 6o III and IV. Fig. VII is a View of the guiding and tearing plate detached. Fig. VIII is an enlarged section of one of the standards. Fig. IX is a plan of the member o of the strip-holder.

1 designates means constructed to hold and guide a portion of the hygienic strip 2 across the open end of the mouth oil the sound-transmitter e. The same may consist in a body formedof a plain strip of sheet metal bent in 7o four members a o o Z and adapted to fasten upon the telephone or other sound-transmitter and constructed to extend ony opposite sides of'the mouthpiece thereof substantially as in the said patented device.l The arm Z of the 75 strip-holder 1 is constructed to form three walls of a tension-guide y for the hygienic strip. With this object in view the end of the body is bent downward to form the tensionguide member Z in the usual manner, and said 8O member l is bent at its edges to form shoulders e, and outside said shoulders is bent upon itselt` to form plate-retainers f to hold the member 3, which forms'the front wall ofthe also made whereby the action of the brake' .Y middle, as indicated at L, so thatwhen the end of the hygienic strip 2 is pointed, as shown in Fig. I, it can be readily passed through the guideway formed between therplate 3 and the arm CZ. The plate 3 presses the sides of the strip against the memberl and holds the 95 same friction-tight, while the greater portion oi' the strip'is free from contact with said "plate 3.

In order to provide a most simple and elficient means for holding the rolled portion /z of the hygienic strip, a strip 4, of sheet-steel or other suitable resilient material, is bent to lit against the arm 7) and to extend from said arm in two inwardly-bowed standards j, which are provided with holes /r to form bearings for the axle 5 of the roll of the hygienic strip. The holes in said standards may extend in bent slots 6 in the inwardly-bowed portion 7 of the standards. Said slots pref- .erably slant downward rearwardly and thcn extend forward and terminate in undercut journal-bearings r. The purpose of this undercut is to prevent the strain of the strip 2 on the roll c' from displacing the axle 5 when the strip is drawn downward to bring a new surface infront of the receiver. Each of the standards j is preferably formed with an inwardly-projeeting boss S at the bearing-holes 71. 'Ihe bosses 8 are held by the resilient standards y' against the roll, near the axis thereof, so that the frictional pressure upon the roll remains constant until the roll is fully unwound.

rIheplate 3 of the tension-guide 1/ is preferably furnished at its edges with shoulders m to lit against the projections f of the arm d to prevent the plate 3 from being forced upward by the strip 2 in the act of tearing.

a designates a rivet, fastening' the resilient strip I to the arm of the body of the holder.

Preferably the strip will be wound in a roll upon a perforated core o, of wood, through which the axle 5 may readily be passed preparatory to applying the strip to the holder. The bosses 8 may press against the wooden Acore o of the roll.

' In practice the hygienic strips will be put up in rolls ready for application to the holder and the free end p of the strip will be pointed to facilitate threadingthrough the open space g at the middle of the plate 3. The roll will be inserted between the standardsyl and the axle 5 brought into the bearing t. Then the point y) of the strip will be. inserted through the space y and the strip drawn down, so that its edges are clasped between the plate 3 and the member (l. Vhen the user desires to bring a new surface into position, he will draw the strip and tear it ofi in the usual way. The plate 3 is wider than the member (l, so that the lower end of the strip is left free behind the plate 3 to be drawn down by the lingers of the user in order to again bring' a new surface into play.

The parts of the strip -holder may be stamped and pressed from three strips of sheet metal or other suitable material, and each of said strips is of a practically plain and simple form, as will readily be understood from the drawings.

The cost of-assembling thepartsis comparatively small owing to simple construction.

9 designates gains desirably formed in the edges of the member of the body to hold the standards y'.

s designates hole for the rivet n.

Vhat I claim, and desire to secure by Letters Patent of the United States, is"

l. A hygienic appliance for a sound-transmitter mouthpiece comprising in combination a flexible strip; means constructed to hold and guide a portion of the strip across the open end of a mouthpiece; an axle carryinga portion of the strip in the form of a roll; and a support for said axle consisting solely of a resilient strip of metal constructed to frictionally contact with the ends of the roll near the axle.

2.
