Be it known thet l, 'll iiiuerr PHILLIPS, a. citizen of the limited ftltstes, sud resident of New York, in the county o'iillew York and State of New York, have invented certeiii new and useful improvements in Com biued Phouographic and Clelephonic Apparatus, of which the following is e specification.

My present invention relates to sound reproducers and more particularly to uppers tus for use alternatively as e phouogrsh or us on amplifying telephone receiver, t .ie latter eplicution more especially for amateur radio purposes.

it is an object of the invention to provide an apparatus of the above type which shell elimi e the need for mounting or dismouuting the phonograph sound box or the telephone receiver with respect to the tone arm in order to change over from phonograph to radio operation uiidvice verse, and which shall yet be capable of use at will, either as e phonograph operated by a record, or as on amplifyingtelephone receiver or loud speaker operable from a radio receiving set. It is another object to provide an apparatus of the above type, the operation of which will he szirtis'lactoii'y either as u phonographor us an amplifying telephone receiver, and which may moreover be employed to pr0- duce novel efi'ects for simultaneous .reproduction of phonograph records, synchronized if desired with complementary tclephonically transmitted messages or selections.

The invention has a preferred application to the substantially conventional phonograph, the tone arm only of which is moditied to provide it double inlet at one of which is connected the usual sound box having a diaphragm actuated from the usual stylus, and to the other oil which is attached a telephone receiver. In the preferred embodimentthe entire weight of the tone arm together with that of the sound box and of the telephone receiver carried thereon, is supported at the pivoted or amplifier end, so that the weight of the telephone receiver which. may be permanently retained on the tone arm shall not increase the pressure of the sound bur: stylus upon the record groove.

In the preferred application the tone arm inlet or nipple for the telephone receiver extends horizontally in axial alignment with the letersl offset or nipple for the sound Serial No. $74,615.

plicatiousp in the accompanying drzrwings in which are shown one or more of various possible embodiments of the several features of this invention, v

Fig. 1 is a fragmentury elevation partly in. section of a preferred embodiment of the iii-- ventiori.

Fig. 2 is a fragmentary plan view on. :2 larger scale and partly in section of a tone arm embodying my invention end Fig. 3 is e fragmentary sectional view of an alternative application. v

Similar reference characters refer to sine ilsr parts throughout the several views oi the drawings.

Referring now to the drawings, I here sho'wu a phonograph cabinet 10, supporting apl'ionogreph record turn table 11 to he rotuted by the usual spring or electric motor (not shown) mounted on the lower surface of motor board 12. Within the cabinet, is the usual amplifier. 13, to the upper end of which is connected the tone arm 1% In the preferred embodiment, the tone arm is pivotully mounted upon a metal support spider 15 secured as by screws 16 to themotor board 12, The spider 15 has s thrust hearing 17 for e cooperating/thrust Toeermg member 18 at the lower surface of a spider 19 in the tone arm. A pin 20 longitudinallythrough spider 19 End secured thereinto, has a bearing in a corresponding elongated hub 21 in the supports spiderlo and coustitutes the pivot mount, which permits the rotary movement of the tone arm across the turn table for playing a record. tone arm is illustrutively shown of the taper form, the amplifier end of which telescopes into the hub 22 of support spider 15 with The "ill

In the referred en'iboslimont the usual ions arm (inscribed is cast with an integral inloit. or niyoplo 30 axially aligned with inlet or ni aplo 24:, and extonrling diametrically opposiio liicroto, and serving as a .mounl for a telephone; receiver of suitable construc" tion. The receiver shown in Fig. 2 is sub sltunlinlly of the usual head set type and in eludes: 1:. casing 31 which may be of vulcan- 'wilsliin which is mounted. the eloctromag netio lolophono coil 333 the .lerniinals of Whioli mo shown at The. magnetic clinis; ooniine i lay u. cap 35 threaded no So ugmu (tho casing nncl formed in the shown, with an integral threadsoc kei. 3? to be. thrcndoxl over the nipple The cud of unmet 3'? preferably forms a met-iii to inclnl bottoming engagement Willi illfi shoulder 38: at the base of tho nipple.

For this;v application, no will lac soon inFig. 3,.the loud speaker atfiaciin'iont neck 3 is simply telescoped by n friction-lint inlotlio nipple 30, the and of sair L noel; preferably bottoming against a. shoulclor ill) iformccl ml; the innor end of said ni plea Flinn, my lone arm um Willi 5-. liencl set. rsceiror filial; has a s; ecinl ljilTfiiXdGti. onlcriorly over nippce 3G. or will: the usual loud speaker phonograph attachment, the neck of which is telessopccl info tins nipple 3G.

ifs viii of course be apparent that a telofriction lit mounl of the telephone resolver may lio-nubslitui ocl for the threaded z 'siuchmen'i shown in Fig. 2 and that in- 5c 2d of the friction mount shown in Fig. 3, mount may lac employed as in F It will. also understood that all." lilo metal lo metal ongagcmeul. lino is sufficiently ligiii incrynsn. cozu z'ossilile washers r gasket-s may be employed ;1 me well understood manner, to assure a sound tight. connection.

The sound box nndllio telephone Receiver boilnxcnmining oflixcd to the tone arm at all times whether the appomtus is USQCi as phonogrnph or as n radio loud s Jenkcr, llic connecting joint for tho sound )OX is not likely to wear loose as in constrimltlons in which the sound box must he slipped out; and the loucl speaker attachment slipped onto the tone arm Whenever the phonograph is to be used for radio reception, and, vicevcrsn, to restore the apparatus for phonograph use. Moroovr the likelihood of mislnying or injuring; the separated Sound box. or receiver, or of scratching furnimm themwith, is wholly obviated in my cmisti-m-tion, in which there no occasion to remove from the tone arm either. the sound l2OX or. the telephone receiver.

T he apparatus is usd as a phonograph in-tlie ordinary manner, it lioing noicd that since the entire weight of the tone arm and associated apparatus is supported 5's the thrust bearing 17, the Weight of? the lclc-j phone receiver at the outer end of lilo tone arm will not add to the pressure of the stylus EZQ'ngninst the record R, The telepllona receiver casing 31 moreover affords :1 con vcnicnt liandlo for uaanipuloting tho tone arm in starting o. record. Vv'hon ilie record selection is completed the sound-box may be thrown liacl: to inoperative position by pivoting about its mounl '26 urrtlioui; intorferoneswith mo telephone receivoi: 31.

To employ the apparatus as a mdio loud 1 box and telephone receiver the quality and 'clearncss of the operation 13 distinctly m1- PIOVBd, both-in phonograph 31nd in radio loud speaker operation. It seems probable that in the operation as a phonograph some; of the vibrations from the diaphragm 28 are transmitted through the connecting air column to the nmgnetic diaphragm 34 and that in the operation as a radio receiver, vibi'p 'tion in'ipressod on the magnetic diaphragm 3% are similarly transmitted to the souk ml box diaphragm. It would appear that in each case the (linphrn m upon which the vi ln'ations are impressewould induce in the other diaphragm vibrations in synchronism or substanlially in synolironism therewith, oncl that; liis causes the 'znelloweal or enrioliod lone quality noted.

My. apparatus is also susceptible of a use which I nclieve is broadly new, for conjoint memes phonograph in synchronism with the corre sponding musical accompaniment played on the record.

lily invention is also an instrumentality tor a distinctly-novel entertainment. A. phonograph musical record Without vocal accompaniment may be played, for instance, and thereupon the entertainer may play the same record which now appears to-include a vocal. accompaniment, the latter produced.

by an assistant in an adjoining room who now sings the accompaniment into a telephone transmitter -wh1ch is connected 1n a wired telephone circuit with the receiver 31 on the telephone.

Other interesting, surprising or ludicrous effects may be produced in manners appan ent from the foregoing.

It will thus be seen that-there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requ'iremei'its'ot practical I As many changes could he made in the above construction and many apparently Widely diiferent embodiments of this inven tion could be made Without departing from the scope thereof, it is intended that all,

matter contained in the alcove description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limited sense.

.Having thus described myin vention, what I claim is new and desire to secure by Letter-s Patent is In a tone arm, for a combined phonograph and radio receiving apparatus, in combinw tlOIhfl. pair of support tubes extending in agrial alignment horizontally from opposite sides of the outer end of said tone arm a sound ,box neck attached to one of said tubes and a telephone receiver having a cap with an integral hub in telescoping relation. with the other said tube.
