LOUIS STEINBERGR, or. NEW YORK, N.`Y.

1 TELEPHoNifi-MOUTHPIEon.

Application filed. June 20,

Be it known that I, LoUis -S'rEixnEnGEin-a citizen of tlie.Uiiited Statcs,.and a resident of the city ot New York, borough o t' Brooklyn, vin the county of. Kings and -State of New York, have invented a new and Improved 'telephone-3,1outhpicce, of which the following is a full, clear, and exact. description. y i' v My invention relates to telephone mouthpieces, iny'uioi'e particular purpose being to provide a type of niouthiiieci-i having upon its outer peripheral edge a strengtliening' member of annular foi-in, separate `trointhc mouthpiece and detachahly connected there- .\v1t li. v

My inveiitioiiiiii'lher conipreheiidsinoui'iting upon .the mouthpiece adjacent to the aforesaid outer' peripheral edge of the saine', a protecting member aud legend plate hav-,

'ing substantially. theloriii of aftlairiii and adapted toili'splay lejjeids, including -iiuinbers--this legend plate beiiiLr iiori'nally locked in posit-ioii by aid of a locking ring.

My invention further. txiiuprehends 'the fitting: of said locking ring iii -position so that it may be turned -to dillerenl. degrees 4and` thereby adjusted so asio bring some of the legends more prominently into View, or into niore favorable positions, the legends plate being then locked or leftfiiee to turn,

As is wel] known iu this-art, the month- `piecesusually employed are made of matclrial which is more oi less brittle., and as the outer peripheral edge ot the n'iouthpiece Ais usually made rei-y thin. it is 'liable to be" broken or chipped from various 'accidental causes. lVhat. I seek to do, therefore, is to accomplish the purpose of protecting this outer peripheral edge by vcovering the same,

` together with the inner "and outer4V portions .of the mouthpiece immediately .adjacent thereto, with thc aforesaid lockingl ring, and -by rounding most of the exposed lsurfaces' of this locking ring,.therebygive the latter such conformity as will render it compara-1 tively immune from most. of the inpirie's otherwise likelyy to take 4place ,from 'accidental causes. The locking ring` thus servesias la shield .for protectingthe adjacent outer portion of the mouthpiece.l lVhile accom-- plishingr this result I take vadvai'itage of the fact. that thtl locking ring may be employed Specification of Letters Patent.

position -a protect-ing meinber'or'legend plate, and by making this legendplateo' 1^ comparatively tough material, such as fiber," A

'or the substance knownin this .artasvelietrose,"'ivhich isA somewhat akin .to iiber-.in its' physical properties, -tlie legend plateitself serres as. a protecting and 'strengtheningI liiiienibei', as well as a means for displaying telephone addresses or other appropriate legends.

' By having 'the looking ring,bind-'firmly` against thelegend plate, as hereinafter de`- scribed, so as .to force the'latter againstth shoulder ,carried by t-he mouthpiecevfofthis' purpose, tight, strong, and .compactconstruction is secured, .the outer edge .of the nioutlipecebeing doubly protected byqtheh locking ring and 'the leUendplate, the va'rions parts thus arrangedD presenting incidm" "tally a neat, and attractive' appearance.

lReference is to bfi-had tothe accompanying drawings forming ai part of this specifi" cation, in' whichl similar characters of'refe'rence indicate corresponding parts in all the views.

Figure '1 "is a.sect-ion,takenv on theline4 1--1 of Fig. 2, showing on anenlarged scale 1 a mouthpiece provided withmy improved l,

locking ring'and protecting member fand 'legend plate; vl `ig. 2 is-fa plan view ,of the mechanism shown in Fig. 1: F iggBrisuperspectire of the body'ineinber of'thenionthf i fpiece: and Fig. 4 is a perspective showing the protecting strengthening locking ring.1

The body portion '5 may-hare the conventional or any desiredforin, andinay be' made of any appropriate-m'aterialg silch s, elec- 1` V trose, fiber, ,hard rubber, or the like, and'in this instance is provided Witha'reduced portioir' threaded 'externally and 'serving as ai stem whereby the 'mouthpieceI maybe mounted upon the fabel-plate'ofthe transmitter. The mouthpie'e'is further .providetliwitl'a perforated'4 artition 7 and -with a-compartment 8, encircled bythe threadedportion 6i The mouthpiece is'ffurther provided-with kerfs, one of which is shown at 10g-for equalizing mechanical strains-when .the mouthpiece is screwed intposi'tion'and-to 'serve vided with a compartment 9, of flaring form,

-body member is provided integrall v with an lannular bead 11, and with an annular shoulder 11a.l extending outwardly from the vbase of said bead. The bead 11 is threaded externally and is smooth internall thesmooth internal surface being substantially parallel with the threaded outer surface, as' will be understood from Fig. 1. At 12 is a locking ring made of metal, fiber, electr-ose' or any other suitable material. and provided with an outer wall12, this outer wall being.

-and ts neatly u on the annular bead. 1l, the threaded sur ace ofthe outerwall 12 '.matingthe outerthreadedsurface of the bead 11 so that the locking ring may be screwed upon the bead. LsThe' flange 121 greatly strengthens the locking ring and protects all o plate having 'generally the formof .a large flat-ring, an

provided with radially disposed 'marks 14 whereby its exposed surface is divided.into sector-likepanels, as shown in Fig. 2, each panel bearing a legend 15 which..

^ ma conveniently be the name and telephone cal of a subscriber.

The xit/gend ringv may be removed entirely and .-in this event the flange 12a of the lockin ring protects not only ,the lockingring, ut also theadjacent portions of the mouthpiece from chipping or breakingdue vto jars,.concussions and the like.v W

en the `legend ring is in position, the

, .llange-.lQserves as a reinforce for `strengthening the' legend ring and parts immediately adjacent, to the same:- -The shape' of 4'the flange 12l is such that a side blow accidentally directed against the outer or free end of the mouthpiece is received against the edge of the ilange,lthis fact serving toractically. increase the strength of the ange and of the lockingring. That is to say,'the

,flange will :stand-a greater -blow or ev'en al' greater -crushin force lif 'the .force be directed against t e ed of the flange. Similarly a blow or crus 1 cidentally against the t gend plate -is receivedz upon the edge of t e same, -the plate and parts adjacent to it being virtually y,

I stronger because of this fact.

' :Ihe-.locking ring 12` and the legend 'ringl 13` may both b e removed from the'moutl1' piece as -indipad in Fig. a. -In thsjeyent, the annular shoulder 11* extends outwardly a little from the adjacent surface of the annu` lar bead v11. The-annular bead 11F is thus" disposed intermediate the ends ofthe mouththe parts. At 13 is a legend g force directed' ac- ,piece and confers considerable strength-upon the mouthpiece. A b low which might otherwise be received uponthe outer edgel of the mouthpiece, if received upon the annular bead 11, is not nearly so'apt-to chip the '70 mouthpiece. v 'Y The operation of mydev/ice is as follows: The body.4 member 5 being mountedzlinthe conventional or anv desired mannerujon the face plate of a transmitter, the legend plate 13 isslipped over -the annular bead 11 and lodged against the annular shoulder 11; tl'rej,l locking ring l2 is next fitted upon the beadA and turned until the edge 12 engages the adjacent surface of the legend platea'nd jams so the legend plate firmly against the annular shoulderll. To adjust the legend plate so as to'change the relative positionsv of" the various legends, the locking ring is turned slightly and thereby loosens the legend plate which' is'then grasped by the operator and turned so as to bring about :the desired adjustment of the legends which it carries. The locking 'ring is then turned .back so as to -jam the le end' plate again against the 90 annular shoul er 11". y j The parts heilig arranged and ad'usted.as above described, the telephone moutpieceas a, whole Ais .greatly strengt1'iened,;. and,C the ring 'and legend.y plate .i s particularly strengthened.4 If, now, anyblowbe -aecif; z dentally directed toward4 the outer edgeof the mouthpiece, such blew will be received for fuse, it may readilyrbe-rem'oved and replaced by a-new one. This isv also .true .of v

the legend plate.

I do -not limit myself to the precise` ar-' rangement. of the parts as shown in the 1,10 drawings, nor to any particular form for any part or parts, nor to the employment in every instance of a separate protecting mem# ber-and'le'gendplate; neither do I limit my# -self to the-inse of any particular material or materials,.thou' h I prefer to employ for the body portion :o :the mouthpiece the insulat in material "-`wellfknown in .this 'nrt as .e ectrose. i
