Telephone instrument apparatus for controlling related equipment and ~or lenabling hands free usaye The present invention is dir~cted to an apparatus which may be operated as auxiliary equipment to, or as an integral part of an ordinary telephone instrument. More particularly, the invention is directed to an apparatus that expands the func-tions of an crdinary telephone instrument ~o include controlsfor the operation of related equipmen-t; and to provide a faceset for using a telephone instrument hands free, thereby ellminatlng the need to hold a handset or to wear a headset.
~s is well known the typical telephone instrument of today consists o~ a handset and a base.
The handset being the unit that houses;
l? a sound transmitter whose sensitivity necessitates that it be held in close proximity to the mouth for satisfactory performance. This portion is frequently re~erxed to as the mouth-piece.

The handset being the unit that houses;
l? a sound transmitter whose sensitivity necessitates that it be held in close proximity to the mouth for satisfactory performance. This portion is frequently re~erxed to as the mouth-piece.
2~ a sound receiver which deli~ers a level of intensity that necessitates it be held in close prox~mity to an ear. This portion is frequently referred to as the earpiece.
The entire unit containing the mouthpiece and earpiece is re-fexred to as the handset possibly because it is apparently designed to be hand-supported during use~ The base is the unit that houses, amon~ other components an "on-ofE" switch, usuall~ o~ the gravity type which is act~vated~deactivated by the absence/presence of the weight of the handset in the cradle. This on-off s~itch controls the circuitry that en-ables the components in the handset to function.
Although the present invention is shown as applied to the common "desk-top" or "table-top" type o~ telephone instru-ment, it may be made to function with any instrument or de-vice where a transmitter-receiver combination unit requires ~37~
that it be supported in close proximity to the moukh and~or ear respectlvely.
During actual use of the telephone ins~rument, the handse~ is raised from a cradle on the base and held in the hand in close proximity to the face ~or contact ~ith the ear and the mouth at the respect~ve ends of the handset. This enables the user to talk into the transmitter at the mouth portion and to receive incomlng signals by wa~ of the recelver in th,e ear 10 portlon. Once the handset is re~oved ~ro~ the cradle, the plunger buttons projectin~ from the base are in the fully ex-tended posltlon activating associated clrcuitry such that any lncoming signals to ~he receiver a~d outgolng si~nals to the transmitter are operat~veO ~s previous~y mentioned, the plun-15 ger ~uttons which are part,o~ the s~itch hook are designed tobe depressed by the sheer weight of the handset resting the cradle of the base of the telephone instrume~t.
Associated with the concept of using the conve~tional tele-20 phone instrument is the need for it:s user to employ one hand 9 and many time~ t~e other"hand, for holdln~ the han~set. This automatically limits the ability to carry on other activities durin~ a telephone convexsationi and introduces the element of fatigue and ~scom~ort b~ reason of the holding process.
The prior art has considered diverse means for overcomin~ these pro~lems, ~ut up u~til the present time, such arrangements have exhi~ted short~omings. For example, ln one apparatus the handset i~ place~ in a receptacle which must be positioned in 30 proximlty to the user, and in turn be con~ined within close proximity to the receptacle. Some addltional availahle de-vices known from the prior art employ alternate approaches none of whlch exhibit the favorable characteristics of the pre-sent invention.

3--In all instances, these arrangements exhibit shortcomings which in some fashion limit the abllity for the user to feel fully free in carrying out his other actlvitiçs while en-gaging in the telephone conversation~ Such priox art equip-ment as was intended to free the arm from holding the handsetrequires the use of cumbersome auxiliary e~uipment, substan-tial amounts of wiring and t~e like, and nonethless fails to provide the necessary flexib~l~ty, where the user feels he is tied ~o the auxiliary e~uipment and must remain within a fixed distance from such equipment.
Also known are outgoin~ devices which emplo~ microphones at d~stances from the user's mouth that have exhibited short-comings, such as: the need to shout to compensate for distance, 15 lack of clarity, intçnsit~ and quality of voice~.. similar to that as heard in a tunnel; inability to maintain privacy when desired, etc.
Accordingly, it is the ~ain ~bject of the prese~t invention to 20 overcome the defects of the prior ~rt.

Stlll another ob~ect i5 to employ means to include apparatus to operate the on~off s~itch in the base of the telephone instrument in l~eu of the wei~ht of the handse~ ordinarily 30 used for that purpose.
A further object ls to pro~ide el~ctron~c cixcuitry ~hereby a low volume sound level of the signal deli~ered to an earpiece may be made variable to volume sound levels to suit th~ user Still another object of the present invention is to provide means whereby related devices and equipment can be readily ac-~3~6,~

The present invent~on basically comprises two distinct ele-ments (see Figs. 1-81 ~hich coopera~e to proyide the user with 25 a simple and efficient means for using a telephone instru-ment while wea~in~ a miniaturized, lig~wei~ht faceset in lieu o~ holdiny the f~miliar han~set which is larger and heavier.
The faceset is electroniaally compatible, and is operational at the same time, as i~ -the handset thus o~ferin~ the user a 30 cholce if desired. The faceset is a miniaturized transmitter/
recei~er unlt which is desi~ned to be worn alon~ the u~er's face in a manner tha-t places the receiver on the ear and the transmitter near the mouth.
35 In this regard, a basic module is employed containing means by which the incoming and outgoing signals normally associ-ated with the conventional telephone instrument are control-~37~6~
led to enable the user to carry out his conversation by meansof the miniaturized faceseti this taking place with conven-ience and comfor~, ~hile at the same time freeing both hands of any additional activities concurrent with the telephone cOnversatiQn. The miniaturlzed, lightwel~ht faceset per-forms better than the ordinary handset part of the conven-tional telephone instrument since the weaxin~ position of the faceset maintains a fixed close proximity bet~een t~e transmitter and the mouth, as well as between the receiyex 10 and the ear. Also provided is the ability to ad~ust the sound ievel delivered to t~e ear.
As sho~n in the accompanying ~'igs. 1~5 ~he miniaturized face-set 1 consists of an elongated brid~in~ membex 2 which bridges 15 the mouthpiece 3 to the earpiece 4 aiong the user's face. As shown, the brid~ing member 2 is o~ a sufficient len~th that the earpiece 4 and the mouthpiece 3 are disposed in proximity ~o the ear and to the mouth, respectiYel~, so as to enable normal telephone conersation to take place. Furthermore, 20 the earpiece 4 i$ pro~ided with a contoured member 5 (see Fig.
3i emanatin~ therefrom, ~h.~ch is curved to allow the earpiece ~ to rest comfortably in proximity to the ear, as the con-toured member S sits ~ehind the ear loke as a support. The contoured member S ~s positionable as i~ F~. 5, to be ori-25 ented so as to fit on either the left or ri~ht ears respect-iYel~ by reversing orientation a~out PiVot 5. This contoured member 5 acts to support the faceset 1 at one end and is fo~med of a flexible material, ~uch as a wire of s~fficient rigidity, to ena~le the user to ~end and adjust s~ae ~o 5 at 30 comfortabl~ behind the ear.
Extending from a portion of the elonyated brid~in~ member 2, is a transverse support member 6~ as shown in Fig. 1, whlch radiates from the brid~in~ member 2 toward the user's nose.
35 The support member 6 is affixed to a member 7 which may be ~376~i~
slidable along the bridging member 2 which may be rigid or flexihle for propex po~itio~n~. ~ccoxdin~ to Fig. 2, a spring member 8 ~ay be disposed within mem~er 7 and serYes to engage the support member 6 along a designate~ pos~tion thereon. This permits ad~ustment of support memher 6 along bridging mem~er 2 for the conuenience of ~he user. Support member 6 is of a sufficient length to seat at its ~ree end ~y means of a concaYe member ~ resting on the user's nose.
This support member 6 is formed of a material such as a bend-able wire or ~l~t strip, and has sufficient f~exibility to be controured along its length to ~it closely to the cheekand nose portions o~ the ~ace respeGtiYely, so as to achie~e comfort and not interfere w~th the user's ~i$ion~ Further-more, at its fre~ end, mç~ber 9 is SQ shaped to comfortably fit and positi~ely engage the nose. The transYerSe support 6 held by brid~ing member 2 may be remoYab~e ~rom t~e bridg-ing member 2 and can be positloned to act and extend from either the right or le~t side depending upon which side the user is employing the miniature ~aceset l.
In addition, where the user may ~lear eyeylasse~, the support 6 may be further positioned and thusly removed from the nose and directed ~pwardly for pos~tlon~ny on an eyeglass ~rame temple to prov~de the necessary s~pport oE the faceset 1 as the eyeglass frame provides the necessar~ nose support.
The miniature faceset is provlded with a plurallty of wires, of ~hich two serye the mouthpiece; and two serye the earpiece, which wires are shown at 17. The wires that emanate from the mouthpiece 3 are con~ected to t~e terminal interior o~
the base 12 of the ~elephone instrument ll ~see Fig. 6~
iden~ically to where the ~ires that emanate fro~ the mouth-piece 13 of handset 14 are connec~ed, so as to transmit a signal into telephone base 12.

.
~37~
In turn, the ~ires leadlng from earpiece 4 o~ miniature face-set 1 are connected to an amplifier ~here the signal is ampli$ied in ~ fashion as will be described hereinafter.
It i5 important to re~lize that the in~entiYÇ faceset 1 is basically intended to be placed in proximity to t~e user's face, per Fig. 1, where the spatial rela~ionshlp of the mouth-piece 3 to the earpiece 4 is such that the elongated bridging member 2 serves as the link therebetween~ The support mem-10 ber 6 is intended to pro~ide the neces$ary support for thepositioning o~ t~e miniaturized faceset at one end, while the contoured member 5 performs an tdent~cal function at the other end. Therefore, at all tlmes the faceset 1 ~il~ remain in a proper posi~ion w~th respect to the user's mouth, and lS ear. ~s previously mentioned, the contoured member 5 is adjustable by the appropriate flexure of its curvature so as to suite the contour of the userls ear, enabling proper posi-tioning of the faceset 1.
20 Fig~ 6 lllustra~es the module 15 ~h;ich acts upon both the instrument base 12 and handset ~4 and will be described here-after. The module lS is a self-contained uni~ ~hich has a num~er of elements that cooperate With the kelephone inskru-ment 11 to enable the miniature faceset 1 to operate. The 25 module is so formed that th handset 14 is in~ended to be laid to rest upon a platform 16 of the module lS where ~he trans-mitter 13 of the handse~ 14 is at a designated location and xecei~er 17 at another loca~on. ~s Will ~e explained here-after, the moaulç 15 is comprised of de~ignated co~ponents 30 which function in con~un~tion with the telephone instrument 11 permitting the miniature faceset 1 worn ~y the user to operate without the need ~or futher handling of telephone instrument.
In actual operation, the handset 14 is placed on platform 16 35 so as to be in close proximity to module 15 (see Fig. 6).
The base 12 of the telephone instrument 11 is placed on a ~L13~
stand 18 of the module 15 beneath exte~da~le arm 19 as shown by the broken lines of arm 19 in Fiy. 7. ~ow the in-ventive apparatus is ready for operation~ As will be ex-plained in more detail hereinafter, the extendable arm 19 is caused to move downwardly per solld line posltlon in Fig. 7, and the switch ~ook or pins 2Q as shown in Fig. 6, are ur~ed to tra~el downwardly. The extendable arm 1~ radiatin~ from the module 15 ls so operable to take the place of handset 14 which normally sits on cradle 21 and engages switch hook 20.
10 Under such conditions an incoming call to the telephone ln-strument 14 will be received as if handset 1~ is at the rest position sn cradle 21 and the switch hook is depressed. Like-wise, the extendable ~rm 19 may be ur~ed upwardly to cause switch hook 20 to eleYate as if the handset 14 were removed 15 from the crad~e 21 o~ the ~ase 12.
In fi~. 9 the elon~ated lever arm 22 is at the reSt position.
T~e arm 22 is pivotall~ mounted at 23 and is spring connected to extending arm 19 through spriny 24. The arm 19 is verti-20 call~ slidable in guides 25, Purth~.r~ore, arm 22 is biasedupwardl~ throu~h sprin~ 26. The ar~l 22 1$ l~tched ~hen in the rest position by latching assem~ly 37 mounted to partition 27 within the housln~ of ~odule 15. R~ way of further explain-lng this function of arm 19, it moves in response to the actu-25 ation of elong~ted arm 22~ ~s preyiously mentioned, extend-in~ arm 19 i5 intended to act upon the s~itch hook or pins 20 o~ the telephone instr~ment 11 in lieu of the conventlonal handset 14.
30 Initlally the base 12 is place~ adjacent the module lS with the extending arm 19 disposed over the switch hook 2Q as shown in Fiy. 10. The arm 22 is maintalned in upward positlon by sprin~ 26. The free end of arm 22 moves upwardly and down-wardl~ ~ithin ~ slot 28 tsee Fig. 6~. In the uppermost posi-35 tion arm 22 is so maintained by sprin~ 26 which permits upwardmovement until barrier 29 of slot 28 is reached.
~37~
Spring 24 maintains the extendin~ arm l9 in contact with ~rm 22 at point 30, bearing against point 31 on arm 22. Thusly, ar~ 19 is also urged to maintain an up~ardly position by spring 26.
Once the user $eeks to emploY the lnve~tion, ~he arm l~ is caused to move down b~ actUAt~ng button 32 tsee Fig. 121 and so depressing samç until elongated arm 22 latches in its most downward po~ition by latch assembly 37. During this downward l0 motion of arm 22, it initially cause$ ar~ l9 to moYe ln con-cert via spring 24. At some point in lts downward mo~ement of arm 19, surface 33 o~ arm l9 contacts and fully depresses switch hook 2~. Continuing downward movement o~ arm 22 into the latched position causes sprin~ 24 to elon~ate because arm 19 is prevented from furt~er do~nward moYçment by engage-ment with the aradle 21 of the instru~ent ll.
The latchin~ operation is shown in Figs. lla-c. Initially per FiyO llb t~e axm 22 is shown de-latched~ ~s arm 22 is 20 urged do~nwardly ~see Fig. llc1 it contacts slopi~g surface 34 of latch 35 and rotates the latch clock~se about pln 36.
A torsion spring 38 serves to ~ias latch 35 in a counter clock-~ise direction. .~5 arm 22 continues its do~nward travel it passes the end o~ sloping Sur~ace 34 and en~a~es the lip 3~
as shown in Fig. l~a. The sprin~ 38 ma~ntains the latch 35 in the po~ition to pre~ent arm 22 $rom raisin~, This is latched positlon. Tc release the latch 35~ the button 40 tsee Fi~. l2~ is depressed causing the plate 41 attached thereto, to impart a down~ard force on polnt 42 of latch 35 ~see Fig. llc~ of su~ficlent ma~nitude to de-latch and sep-arate arm 22 from lip 3~. T~e button 40 is affixed to a s~aft 43 which is cons~rained to move in a channel 44 ~ormed of boss 45. The shaft 43 is biased upwardly by sprln~ 46.
~fter de-latching as described above, arm ~2 moves upward 35 under action of sprin~ 26 to cause arm 19 to release the switch hook 20 as described above.
~3~
The module 15 has a slidable panel 15' and contains t~e nec-essary actuating elements and electrical circuitry for intro-ducing into and out o$ electrical circuit relationship the various electrical ~ignals that are necessar~ for providing the multiplicity of functions to the ~re$ent invention.
~ore specifically, the module lS as sho~n in Figs. 6 and 8 houses a plurality of input and output ~acks Jl, J2, J3, etc., and s~itches S~l, $N2 ~see Fig. 17l etc., as ~ill be described hereafter, a source of electrical ener~y, i.e~ a plurality of batteries ~7 for the associated circuitry; a speaker 48 mounted beneath the mod~le platform 16 in prox~mity to the location ~here the transmitter 13 of the instrument handset 14 is at rest; an induction c~il 49 ~see Fig, 17~ is also beneat~ t~e platform 16 and i5 disposed in proximi~y to the receiver 17. ~ illustrated ln Fig~ 17, an amplifier 50 having an associated potentiometer 51 .~s in circuit relation to the aforementioned elements is employed for handling electrical signals into and out o~ the in~entiye handset 1.
In t~e mode of operation accord~ng to Fig. 6, the te~ephone instrument 1~ is placed on ~he module 15 with the transm~t-~e~ 13 on the platform 16 positioned above the speake~ 48 and the receiYer 17 on the pla~fo~n a~o~e induction coil 49.
The base 12 of the instrument 11 ~s placed on stand 18 which ~orms t~e lower part of the module 15 and actuatiny o~ button 32 in a downward dirèct~on causes the switch hhok 20 to he depressed t~rough the ac~ion of extendable arm ~ as has ~een explained~
The circuitry forming part o~ the pre ent invention ~see Fig.
17~ involves the use of an induction coil 49 connected to am-plifier 50 ~hich is energized through batteries 47 by actu-ation of SNl. The voice signal received in the receiver 17 of set 14 is picked up by the coil 49 and transmitted to amplifier 5Q and provides an output signal to jacks 35, 34 , 66~
and J3. The intensity o~ the outp~t signal o~ amplifier 50 can ~e varied in accordance with a settin~ of potentiometer 51 in circuit xelationship therewith thxou~h adjustin~ wheel 52 (see Fi~. 6~.
~s shown in F~g. 13, t~e lever arm 22 is illustrated in two positions. The ~roken line position repre~ent~ the arm 22 in the de-latched position; w~ere~, the solid drawin~ of arm 22 represents the la~ched position~
Actuation of th~ five sw~ches S~1 $~5 is caused by the move-ment o~ arm 22. $W~ 2, SW3, are leaf type switches and move from ~ çlosed to an open contack $tate when the ~ever arm 22 moves downward as shown in Fig. 14~thexeby causing contacts C1 and C2 to open. S~4 is a leaf t~pe switch which changes from an open ~o a closed sta~e, as shown in Fig. 15, when lever arm 22 moves down~ard thereby, cuasing the contacts C3, ~ to move clo$e. S~l-SW4 main~ain a new contact posi~
tlon when arm 22 ls latched. Figs. 14-15 i~lustrate movement of the leaves mountlng the switch co~tacts in response to the action of arm 22~

Fig. 16~ illustrates leYer arm 22 in the iatched posi-tion. Fi~. 16C ~llustrate~ the le~er arm 22 proceeding up-ward from the latched to the de-latched position.
The switch assembly SW5 comprlse~ a switch 57, o~ a leaf type, with an actuator 63. The actuator 63 is pivotally mounted at 64 on arm 59 whic~ in turn is pivotally mounted at 60. Leaf 61 of switch 57 biases actuator 63 a~ainst stop 66, the stop 66 in turn is affixed to arm 59. Thusly, arm 59 is urged 3~61~
upward against stop 62. Further biasing of actuator 63 against stop 66 is carried out b~ torsio~ spring 65 kiasin~
actuator 63 against skop 66. According to Fig. 16 as lever arm 22 descends, it contacts end 68 o~ actuator 63 and contin-ued movement of l~ver arm 22 per Fi~. 16a (down~ard~ towardthe latched position, cause actuator 63 to move downward and urges arm 59 to move downward and PiYot about point 6Q. In this operation, actuator 63 causes leaf 61 to make contact with leaf 67 and switch 57 of switch assem~ly $~5 ls closed.
Continued movement of lever arm 22 as show~ in Fig. 16b causes lt to move into the latched position and ~ermits actuator 63 to return to its rest position as the tension of leaf 61 which is biased upwardly, returns to its rest po~ition`free rom contact ~ith leaf 67, leaving switch 57 o switch assem-bl~ S~5 in an open ska~e.
In moving leY~r arm 22 from the de-latched to the latched condition, the switch S~5 moment~rily closes. In proceeding from the latched to the de-latched condition as shown in FigO
16c, the lever arm 22 contacts the end of arm 63 ca~sing it to rotate cloc~wise. $ince arm 59 is blocked by stop 62 from moving upwardly, arm 63 must rotate about pivot ~
allowing le~er arm 22 to pass by ar~ 63 without movement of arm 59. Torsion spring 65 returns arm 63 to the normal po~i-tion as lever arm 22 moves into the de-latched condition.
In this fashion lever arm 22 retur~s to the de-latched condi-tion without actuak~ng s~itch 57.
Jack 33 is an output ~ack which is en~agable with plug P3 that in turn is connected to ~he airpiece 4 of the inventi~e faceset 1. Since Jl and Pl as well as ~2 and P2, are engaged respectivel~, aparallel tal~ path has been established from the mouthpiece 3 to the telephone instrument 11 which is bridged to terminals connecting transmitter 13 of handset 14 in base 12. A received signal from receiver 17 is directed through coil 49 to ampliEier 50 and through J3 and P3 to earpiece 4. Volume control 51 governs the voice level into the earpiece 4. Jack 4 may be employed to connect into an auxi-liary speaker tnot sho~lnl through a suitable plu~, whereby the voice receiYed in ~he handse~ 14 proYides a signal ~hich is picked-up by coil 49, ampli~ied and transmltted as an output signal into an auxillary speaker plu~ged in J4. The jack 35 provides an input signal for a tape recorder or for a conference call which will tdependin~ on the connection out of 35~ permit the recording of a message simultaneous to the carryin~ on of a conversation, or also would permit the input signal to a aon~erence call unit where a multiple dis-cussion may be h~d.
As previously ment~oned, SWl a~tuation, control the jacks J3 throu~h J5 ~hich a~e bridged to~e~her.
3acks 31 and J2 are bridged to one anQther and serve to enable connection of the mouthpiece 3 of the inYentive faceset l with the terminals in base 12 that are connected to transmitter 13 of handset 14. Jac~ Jl is en~aged b~ ~l ~hich ls directly connected to the telep~one instr~ent ll. The signal out o~
Pl is transmitte~ to terminals in base 12, which terminals are connected to mouthpiece 13. Once P2 which connected to ~he mouthpiece 3 o~ t~e inVentive faceset l, en~a~es Jl, the vo~ce signal froM the faceset 1 is tr~ns~itted directl~ to telephone instru~en~ ll. The use of brid~ed jacks ~l ~nd J2 prov~des a ~onvenience connection and serves to ~lend into one centralized panel for connectio~s.
In other words, the spoken word ~hrough inYentive f aceset mouthpiece 3, which houses microphone, i.e. a c~rbon microphone is transmitted from the mouthpiece and into J2 through P2 and then is transmitted through Pl tbeing connected to J1) and to the telephone instrument ll for transmission else-where.

The module also contains jacks J6, J7, J8, J9 each of which are, respectively, in electrical çircuit relation with as-sociated switches $~2, SW3, S~4 and SW5. The ~acks provide the means by which auxlliary services ma~ be incorporated to function wi~h the telephone. The contacts of S~2-S~5 are actuated ln response to the movement of lever arm 22 as described above.
The jack J~ i$ controlled ~ switch SW5, and is designed for 10 use with a plug that connects to a date-time recording machine.
As previously explained, $~5 wlll be ac~uated on the downward stroke o~ lever arm 22 that simultaneously causes extending arm 19 to depress switchhook 20, consequently the date-time recordin~ machine is activated to stamp the time when a tele-phone call is terminated. Because toll charges based ontlme do not begin the moment switchhook 20 rises ---- as there ~5 no charge ~ox time to dial, nor for wrong number calls, nor for ealls invo~vln~ intercept oper~tors, nor for calls with telephone company operators, nor for calls involving telephone company business, no-answer calls, etc. etc. ----~witch $~6 is a momentary type, that ma~v be depressed by the telephone user ko actiVa~e the date-time recording machine to stamp the ~ime ~hen it is determined that timin~ should commence tdiStant part~ answers~ etc.~. Switch S~6 is bridged to ~WS, tsee Fig. 17~ and is located on the panel of module 15 that houses jacks Jl through 310 tsee Fig. 6)~
~ack J8 is c~nnec~d to switch S~4, Flg. 15 talready described~
and seryes to accommodate a plug eonnected to a speaker of a radio, television or of some other l'loadspeaking" unit.
In raising the posltion of lever arm 22 which enables s~itch-hook 20 of the telephone instrument to rise tphone turned "on"), the swi~ch S~4 is placed in the open state automati-cally causing the radlo, televlsion, etc. to become silent.
Conversely, loweriny lever arm 22 to turn the telephone in-strument off, will cause switch SW4 to be in the closed state, automaticall~ restoring the sound from the radio, television, etc.

Jack ~7 is designed to accommodake a plug connected to a voice xecording machine, and connected to swikch S~3 per Fig. 14, for use to automatlçally "start" and "stop" the motion of a voice recording machine as the phone is "an-swered" and "~ung up" respectiYel~, Down~ard movement ofthe s~itchhook 20 throug~ movement of lever arm 22 causes contacts Cl and C2 of switch S~3 ko open, simultaneously stopping the motion of khe recordin~ machine, ~bY~ousl~, the reverse process causes the contacts of switc~ S~3 to close, simultaneously putting the recordin~ machine in mo-tion.
Jack 36 is connected to switch S~2 and ~s desi~ned to oper-ate in a manner ldenk~call~ to that o~ switch $~3 explained above. ~oweYer, ~ack ~6 is intended to serve as an on~off s~ikch for the operation of an independent ~oice kransmitter 53, to be discussed hexeina~ter~
Jack 310 (see Fig. 6~ is connected ko speaker 48 and is intended for a plug that is connected to a source of sound to be direcked to mouthpiece 13 of handset 14 resting on plat-fo~n 16. Sound may be to and from one or more nearby tele-phones, a voice transmitter Cto ~e di$cussed hereinafter~, background music, etc. 3ac~ J10 also can be made to connect to a junct~on box ~here~ two or more nearby telephones can be unlted in a joint conference. In this s~tuation, a con-nection is established bet~een 34 or 35, see Fi~. 17, of each telephone to be involved and ~ed into ~ junction box as a common input; and in turn is connected as a common output to jack J10 of each of the in~olved modules 15 ttele-phones~, see Fig~ 6. In this manner, the telephone user can simultaneously talk to each of the connected telephones; and each of the telephones in turn can ~e directin~ conversation to the telephone user and the other telephones at the same time-.

The present invention also contemplates an alternate embodi-ment (see Fig. 17~ which does not necessîtate the need for connecting the invent~ve faceset 1 to the telephone instru-ment 11 by wire as men~ioned herebefore; the broken line con-nections of Fig. 17 are employed ln this instance. In thisregard, a transmitter 53 employ~ng an input ~ack Jll con-nected to amplif~ax 5~ has a po-tent~ometer 55 and ~ source of electrical e~ergy 56 associated therewikh~ The inventlYe faceset 1 in t~is instance employs a mouthpiece 3' ~ormed of a microp~one i.e. a dynamic microphone, that ls connected b~ P4 to 311, so that the si~nal from mouthpiece 3' is fed to transmitter 53 through ampli~ier 54 and ouk to P6, which is connected into speaker ~ack J10 and also connected to speaker 48 disposed in module 15 beneath the transmitte~ 13 of the 15 handset 14 resking on the module. The potentiometer 55 serves to adjust the output level of speaker 48 as it transmits the voice out of handsek 1 directly into transmitter 13 of the handset 14 whlch is disposed on the platform 16.
20 Sound is received by the user of faceset 1 in a fashion identi-cal to that set forth in the first menkioned embodimen~ namely, the voice signal is pi~ked up from receiYer ~7 and directed through an induction coil 49, is t~en amplified by amplifier 5Q and is trans~i~ted ~hrough the output jack J3 directly 25 through plug P3' connection the e~rpiece 4l of the ~nventive faceset 1. The module 15 is pro~ided with a ~ck J5 which is connected wi~h P5 leadin~ from the source of electrical energy 56 of transm~tter 53. A~ter plug P5 is connected to jack ~6, the transmitter is actuated b~ switch S~2 in a manner previ 30 ously described.
The em~odiment employ~ng transmitter 53 enables the use of the in~entive faceset 1 without the need for any wired connection into the telephone instrument 11.
In conclusion, the presen-t invention is directed to an appara-tus which may be operated as auxiliar~ e~uipment to, or as an integral part of, an ordinary telephone in~tru~ent. More par-ticularly, the invention makes possible the following fea~ures:
1. ~ lightweight, miniaturized receiYer-transmitter unlt tht can be conveniently "worn" ~y user, thereby obviating the need to l'hold" a weighty telephone handset, or to wear a headset.
2. A mechanism -to depress~release the on-off switch;
thereby eliminatin~ the need to remove~replacç
the handset ~or that purpose.
3. Associated electronic circultry ena~ling the user to regulate the amplitude of the incomin~
sound; the transmission of sound to ~ ~ape, or other recording machine, auxi~iary s~ea~er~s], conference calls, etc., the auto~atic s~itching of a tape, or other, recordin~ machine as t~e telephone itself is s~multaneousl~ being s~itched on-off; and activation of a time-date record-ing mac~ine at the start and termination of each phone call,
Also known are outgoin~ devices which emplo~ microphones at d~stances from the user's mouth that have exhibited short-comings, such as: the need to shout to compensate for distance, 15 lack of clarity, intçnsit~ and quality of voice~.. similar to that as heard in a tunnel; inability to maintain privacy when desired, etc.
Accordingly, it is the ~ain ~bject of the prese~t invention to 20 overcome the defects of the prior ~rt.
further object of the prese~t invention is to provide means ~hereby a faceset can function in llèu of a hand supported or a hea~ supported ~oice transmitter~recçi~er combination 25 unit.
Stlll another ob~ect i5 to employ means to include apparatus to operate the on~off s~itch in the base of the telephone instrument in l~eu of the wei~ht of the handse~ ordinarily 30 used for that purpose.
A further object ls to pro~ide el~ctron~c cixcuitry ~hereby a low volume sound level of the signal deli~ered to an earpiece may be made variable to volume sound levels to suit th~ user Still another object of the present invention is to provide means whereby related devices and equipment can be readily ac-~3~6,~
tivated/deactivated in concer~ with use and ~on-usage of the telephone instrument.

The present invent~on basically comprises two distinct ele-ments (see Figs. 1-81 ~hich coopera~e to proyide the user with 25 a simple and efficient means for using a telephone instru-ment while wea~in~ a miniaturized, lig~wei~ht faceset in lieu o~ holdiny the f~miliar han~set which is larger and heavier.
The faceset is electroniaally compatible, and is operational at the same time, as i~ -the handset thus o~ferin~ the user a 30 cholce if desired. The faceset is a miniaturized transmitter/
recei~er unlt which is desi~ned to be worn alon~ the u~er's face in a manner tha-t places the receiver on the ear and the transmitter near the mouth.
35 In this regard, a basic module is employed containing means by which the incoming and outgoing signals normally associ-ated with the conventional telephone instrument are control-~37~6~
led to enable the user to carry out his conversation by meansof the miniaturized faceseti this taking place with conven-ience and comfor~, ~hile at the same time freeing both hands of any additional activities concurrent with the telephone cOnversatiQn. The miniaturlzed, lightwel~ht faceset per-forms better than the ordinary handset part of the conven-tional telephone instrument since the weaxin~ position of the faceset maintains a fixed close proximity bet~een t~e transmitter and the mouth, as well as between the receiyex 10 and the ear. Also provided is the ability to ad~ust the sound ievel delivered to t~e ear.
As sho~n in the accompanying ~'igs. 1~5 ~he miniaturized face-set 1 consists of an elongated brid~in~ membex 2 which bridges 15 the mouthpiece 3 to the earpiece 4 aiong the user's face. As shown, the brid~ing member 2 is o~ a sufficient len~th that the earpiece 4 and the mouthpiece 3 are disposed in proximity ~o the ear and to the mouth, respectiYel~, so as to enable normal telephone conersation to take place. Furthermore, 20 the earpiece 4 i$ pro~ided with a contoured member 5 (see Fig.
3i emanatin~ therefrom, ~h.~ch is curved to allow the earpiece ~ to rest comfortably in proximity to the ear, as the con-toured member S sits ~ehind the ear loke as a support. The contoured member S ~s positionable as i~ F~. 5, to be ori-25 ented so as to fit on either the left or ri~ht ears respect-iYel~ by reversing orientation a~out PiVot 5. This contoured member 5 acts to support the faceset 1 at one end and is fo~med of a flexible material, ~uch as a wire of s~fficient rigidity, to ena~le the user to ~end and adjust s~ae ~o 5 at 30 comfortabl~ behind the ear.
Extending from a portion of the elonyated brid~in~ member 2, is a transverse support member 6~ as shown in Fig. 1, whlch radiates from the brid~in~ member 2 toward the user's nose.
35 The support member 6 is affixed to a member 7 which may be ~376~i~
slidable along the bridging member 2 which may be rigid or flexihle for propex po~itio~n~. ~ccoxdin~ to Fig. 2, a spring member 8 ~ay be disposed within mem~er 7 and serYes to engage the support member 6 along a designate~ pos~tion thereon. This permits ad~ustment of support memher 6 along bridging mem~er 2 for the conuenience of ~he user. Support member 6 is of a sufficient length to seat at its ~ree end ~y means of a concaYe member ~ resting on the user's nose.
This support member 6 is formed of a material such as a bend-able wire or ~l~t strip, and has sufficient f~exibility to be controured along its length to ~it closely to the cheekand nose portions o~ the ~ace respeGtiYely, so as to achie~e comfort and not interfere w~th the user's ~i$ion~ Further-more, at its fre~ end, mç~ber 9 is SQ shaped to comfortably fit and positi~ely engage the nose. The transYerSe support 6 held by brid~ing member 2 may be remoYab~e ~rom t~e bridg-ing member 2 and can be positloned to act and extend from either the right or le~t side depending upon which side the user is employing the miniature ~aceset l.
In addition, where the user may ~lear eyeylasse~, the support 6 may be further positioned and thusly removed from the nose and directed ~pwardly for pos~tlon~ny on an eyeglass ~rame temple to prov~de the necessary s~pport oE the faceset 1 as the eyeglass frame provides the necessar~ nose support.
The miniature faceset is provlded with a plurallty of wires, of ~hich two serye the mouthpiece; and two serye the earpiece, which wires are shown at 17. The wires that emanate from the mouthpiece 3 are con~ected to t~e terminal interior o~
the base 12 of the ~elephone instrument ll ~see Fig. 6~
iden~ically to where the ~ires that emanate fro~ the mouth-piece 13 of handset 14 are connec~ed, so as to transmit a signal into telephone base 12.
"
.
~37~
In turn, the ~ires leadlng from earpiece 4 o~ miniature face-set 1 are connected to an amplifier ~here the signal is ampli$ied in ~ fashion as will be described hereinafter.
It i5 important to re~lize that the in~entiYÇ faceset 1 is basically intended to be placed in proximity to t~e user's face, per Fig. 1, where the spatial rela~ionshlp of the mouth-piece 3 to the earpiece 4 is such that the elongated bridging member 2 serves as the link therebetween~ The support mem-10 ber 6 is intended to pro~ide the neces$ary support for thepositioning o~ t~e miniaturized faceset at one end, while the contoured member 5 performs an tdent~cal function at the other end. Therefore, at all tlmes the faceset 1 ~il~ remain in a proper posi~ion w~th respect to the user's mouth, and lS ear. ~s previously mentioned, the contoured member 5 is adjustable by the appropriate flexure of its curvature so as to suite the contour of the userls ear, enabling proper posi-tioning of the faceset 1.
20 Fig~ 6 lllustra~es the module 15 ~h;ich acts upon both the instrument base 12 and handset ~4 and will be described here-after. The module lS is a self-contained uni~ ~hich has a num~er of elements that cooperate With the kelephone inskru-ment 11 to enable the miniature faceset 1 to operate. The 25 module is so formed that th handset 14 is in~ended to be laid to rest upon a platform 16 of the module lS where ~he trans-mitter 13 of the handse~ 14 is at a designated location and xecei~er 17 at another loca~on. ~s Will ~e explained here-after, the moaulç 15 is comprised of de~ignated co~ponents 30 which function in con~un~tion with the telephone instrument 11 permitting the miniature faceset 1 worn ~y the user to operate without the need ~or futher handling of telephone instrument.
In actual operation, the handset 14 is placed on platform 16 35 so as to be in close proximity to module 15 (see Fig. 6).
The base 12 of the telephone instrument 11 is placed on a ~L13~
stand 18 of the module 15 beneath exte~da~le arm 19 as shown by the broken lines of arm 19 in Fiy. 7. ~ow the in-ventive apparatus is ready for operation~ As will be ex-plained in more detail hereinafter, the extendable arm 19 is caused to move downwardly per solld line posltlon in Fig. 7, and the switch ~ook or pins 2Q as shown in Fig. 6, are ur~ed to tra~el downwardly. The extendable arm 1~ radiatin~ from the module 15 ls so operable to take the place of handset 14 which normally sits on cradle 21 and engages switch hook 20.
10 Under such conditions an incoming call to the telephone ln-strument 14 will be received as if handset 1~ is at the rest position sn cradle 21 and the switch hook is depressed. Like-wise, the extendable ~rm 19 may be ur~ed upwardly to cause switch hook 20 to eleYate as if the handset 14 were removed 15 from the crad~e 21 o~ the ~ase 12.
In fi~. 9 the elon~ated lever arm 22 is at the reSt position.
T~e arm 22 is pivotall~ mounted at 23 and is spring connected to extending arm 19 through spriny 24. The arm 19 is verti-20 call~ slidable in guides 25, Purth~.r~ore, arm 22 is biasedupwardl~ throu~h sprin~ 26. The ar~l 22 1$ l~tched ~hen in the rest position by latching assem~ly 37 mounted to partition 27 within the housln~ of ~odule 15. R~ way of further explain-lng this function of arm 19, it moves in response to the actu-25 ation of elong~ted arm 22~ ~s preyiously mentioned, extend-in~ arm 19 i5 intended to act upon the s~itch hook or pins 20 o~ the telephone instr~ment 11 in lieu of the conventlonal handset 14.
30 Initlally the base 12 is place~ adjacent the module lS with the extending arm 19 disposed over the switch hook 2Q as shown in Fiy. 10. The arm 22 is maintalned in upward positlon by sprin~ 26. The free end of arm 22 moves upwardly and down-wardl~ ~ithin ~ slot 28 tsee Fig. 6~. In the uppermost posi-35 tion arm 22 is so maintained by sprin~ 26 which permits upwardmovement until barrier 29 of slot 28 is reached.
~37~
Spring 24 maintains the extendin~ arm l9 in contact with ~rm 22 at point 30, bearing against point 31 on arm 22. Thusly, ar~ 19 is also urged to maintain an up~ardly position by spring 26.
Once the user $eeks to emploY the lnve~tion, ~he arm l~ is caused to move down b~ actUAt~ng button 32 tsee Fig. 121 and so depressing samç until elongated arm 22 latches in its most downward po~ition by latch assembly 37. During this downward l0 motion of arm 22, it initially cause$ ar~ l9 to moYe ln con-cert via spring 24. At some point in lts downward mo~ement of arm 19, surface 33 o~ arm l9 contacts and fully depresses switch hook 2~. Continuing downward movement o~ arm 22 into the latched position causes sprin~ 24 to elon~ate because arm 19 is prevented from furt~er do~nward moYçment by engage-ment with the aradle 21 of the instru~ent ll.
The latchin~ operation is shown in Figs. lla-c. Initially per FiyO llb t~e axm 22 is shown de-latched~ ~s arm 22 is 20 urged do~nwardly ~see Fig. llc1 it contacts slopi~g surface 34 of latch 35 and rotates the latch clock~se about pln 36.
A torsion spring 38 serves to ~ias latch 35 in a counter clock-~ise direction. .~5 arm 22 continues its do~nward travel it passes the end o~ sloping Sur~ace 34 and en~a~es the lip 3~
as shown in Fig. l~a. The sprin~ 38 ma~ntains the latch 35 in the po~ition to pre~ent arm 22 $rom raisin~, This is latched positlon. Tc release the latch 35~ the button 40 tsee Fi~. l2~ is depressed causing the plate 41 attached thereto, to impart a down~ard force on polnt 42 of latch 35 ~see Fig. llc~ of su~ficlent ma~nitude to de-latch and sep-arate arm 22 from lip 3~. T~e button 40 is affixed to a s~aft 43 which is cons~rained to move in a channel 44 ~ormed of boss 45. The shaft 43 is biased upwardly by sprln~ 46.
~fter de-latching as described above, arm ~2 moves upward 35 under action of sprin~ 26 to cause arm 19 to release the switch hook 20 as described above.

The module 15 has a slidable panel 15' and contains t~e nec-essary actuating elements and electrical circuitry for intro-ducing into and out o$ electrical circuit relationship the various electrical ~ignals that are necessar~ for providing the multiplicity of functions to the ~re$ent invention.
~ore specifically, the module lS as sho~n in Figs. 6 and 8 houses a plurality of input and output ~acks Jl, J2, J3, etc., and s~itches S~l, $N2 ~see Fig. 17l etc., as ~ill be described hereafter, a source of electrical ener~y, i.e~ a plurality of batteries ~7 for the associated circuitry; a speaker 48 mounted beneath the mod~le platform 16 in prox~mity to the location ~here the transmitter 13 of the instrument handset 14 is at rest; an induction c~il 49 ~see Fig, 17~ is also beneat~ t~e platform 16 and i5 disposed in proximi~y to the receiver 17. ~ illustrated ln Fig~ 17, an amplifier 50 having an associated potentiometer 51 .~s in circuit relation to the aforementioned elements is employed for handling electrical signals into and out o~ the in~entiye handset 1.
In t~e mode of operation accord~ng to Fig. 6, the te~ephone instrument 1~ is placed on ~he module 15 with the transm~t-~e~ 13 on the platform 16 positioned above the speake~ 48 and the receiYer 17 on the pla~fo~n a~o~e induction coil 49.
The base 12 of the instrument 11 ~s placed on stand 18 which ~orms t~e lower part of the module 15 and actuatiny o~ button 32 in a downward dirèct~on causes the switch hhok 20 to he depressed t~rough the ac~ion of extendable arm ~ as has ~een explained~
The circuitry forming part o~ the pre ent invention ~see Fig.
17~ involves the use of an induction coil 49 connected to am-plifier 50 ~hich is energized through batteries 47 by actu-ation of SNl. The voice signal received in the receiver 17 of set 14 is picked up by the coil 49 and transmitted to amplifier 5Q and provides an output signal to jacks 35, 34 , 66~
and J3. The intensity o~ the outp~t signal o~ amplifier 50 can ~e varied in accordance with a settin~ of potentiometer 51 in circuit xelationship therewith thxou~h adjustin~ wheel 52 (see Fi~. 6~.
~s shown in F~g. 13, t~e lever arm 22 is illustrated in two positions. The ~roken line position repre~ent~ the arm 22 in the de-latched position; w~ere~, the solid drawin~ of arm 22 represents the la~ched position~
Actuation of th~ five sw~ches S~1 $~5 is caused by the move-ment o~ arm 22. $W~ 2, SW3, are leaf type switches and move from ~ çlosed to an open contack $tate when the ~ever arm 22 moves downward as shown in Fig. 14~thexeby causing contacts C1 and C2 to open. S~4 is a leaf t~pe switch which changes from an open ~o a closed sta~e, as shown in Fig. 15, when lever arm 22 moves down~ard thereby, cuasing the contacts C3, ~ to move clo$e. S~l-SW4 main~ain a new contact posi~
tlon when arm 22 ls latched. Figs. 14-15 i~lustrate movement of the leaves mountlng the switch co~tacts in response to the action of arm 22~
Fig. 16 illustxates $witch ~W5 in the open state with lever arm 22 in t~e de-latched ~a3~0~, -F~ A ~ho~s lever arm 22 moving from the de~latched po~ition to the ~atched posi-tion. Fig. 16~ illustrates leYer arm 22 in the iatched posi-tion. Fi~. 16C ~llustrate~ the le~er arm 22 proceeding up-ward from the latched to the de-latched position.
The switch assembly SW5 comprlse~ a switch 57, o~ a leaf type, with an actuator 63. The actuator 63 is pivotally mounted at 64 on arm 59 whic~ in turn is pivotally mounted at 60. Leaf 61 of switch 57 biases actuator 63 a~ainst stop 66, the stop 66 in turn is affixed to arm 59. Thusly, arm 59 is urged 3~61~
upward against stop 62. Further biasing of actuator 63 against stop 66 is carried out b~ torsio~ spring 65 kiasin~
actuator 63 against skop 66. According to Fig. 16 as lever arm 22 descends, it contacts end 68 o~ actuator 63 and contin-ued movement of l~ver arm 22 per Fi~. 16a (down~ard~ towardthe latched position, cause actuator 63 to move downward and urges arm 59 to move downward and PiYot about point 6Q. In this operation, actuator 63 causes leaf 61 to make contact with leaf 67 and switch 57 of switch assem~ly $~5 ls closed.
Continued movement of lever arm 22 as show~ in Fig. 16b causes lt to move into the latched position and ~ermits actuator 63 to return to its rest position as the tension of leaf 61 which is biased upwardly, returns to its rest po~ition`free rom contact ~ith leaf 67, leaving switch 57 o switch assem-bl~ S~5 in an open ska~e.
In moving leY~r arm 22 from the de-latched to the latched condition, the switch S~5 moment~rily closes. In proceeding from the latched to the de-latched condition as shown in FigO
16c, the lever arm 22 contacts the end of arm 63 ca~sing it to rotate cloc~wise. $ince arm 59 is blocked by stop 62 from moving upwardly, arm 63 must rotate about pivot ~
allowing le~er arm 22 to pass by ar~ 63 without movement of arm 59. Torsion spring 65 returns arm 63 to the normal po~i-tion as lever arm 22 moves into the de-latched condition.
In this fashion lever arm 22 retur~s to the de-latched condi-tion without actuak~ng s~itch 57.
Jack 33 is an output ~ack which is en~agable with plug P3 that in turn is connected to ~he airpiece 4 of the inventi~e faceset 1. Since Jl and Pl as well as ~2 and P2, are engaged respectivel~, aparallel tal~ path has been established from the mouthpiece 3 to the telephone instrument 11 which is bridged to terminals connecting transmitter 13 of handset 14 in base 12.
