` f To'olZ wwm it may concern:

Be it known that I, JoHN B. BnowNING, ,7. a citizen of theUnited States, and a resident IofCamden, county of Camden, and State of @New Jersey, have yinvented certain new and useful Improvements. in rlalking-Machines, ;o'fgwhich'the following is' a ful complete, 'fjfand exact disclosure, reference being had to l. "fthe accompanying drawings, formin'gaa part mogf this s ecification. 'i

lvide ina talking machine a plurality 'of sound boxes, arranged ,to' reproduce' either.

""sinriultaneously or separately the same tones ""dfirom a. single record,` and to arrange the x,said boxes so that the', operator is enabled to change the volume and vquality of the sound iatwill, by raising one box while the other A @continues playing; to provide means where' -`v2 )`,b'y apair 'of independent sound boxes may s and 7 are a sideelevation and a longitudi- 'nal central section respectively of a detail :""35 ioflthe same; Figs.'8,f`9 and`10 are a rear, a

fragmentary central sectional, and a fragmentary bottom view respectively, of an improved sound box forming a part of this in- ,n a Verition, and Fig. 11 is a diagrammatic view 0 Iqnt" a detail of the same. "n

Referring to the drawing's, one embodinient of this invent-ion comprises two indepepdent fsound boxes orreproducers having A, asings 1 and 2 respectively, each having a '45 'cylindrical bore, and containing a circular diaphragm 2 made of any suitable material, preferably mica having a transversely rounded peripheral edge. Each diaphragm is mounted in a split annular rubber tube or and the outer surface of which is rounded transversely and contacts with the surface.

The 4o jects of vthis invention are-tol pro` 5b gasket 3, which contacts only with theV4 rounded peripheral .ctlgfrf the diaphragm of the casing and prevents tbe diaphragm vfrom contactin withI any part ofthe casing. This split gas et'alsoserves as a packi and as an insulator fon the dia hragm an prevents the edge of the diap ra from splitting, and engaging the-round-gd' edge only ofl the diaphragm, forms amounting very freel7 throughoutl its entire area. i

A tubu ar rubberA asket 4 is inserted each sound box casing to hold the split gasket 3 and its diaphragm 2"in positlon, and both gaskets are held in plaoe'by a metallic 'ring/4 which is inserted through the open face of the casingand fits snugly within the bore of the casing, and which maybe lafttached to the casing in any suitable manner.

A stylus bar 5, is phonetically connected to eachdiaphragm 2 means -andfextends through openings pr0 vided therefor inthe gasket' 4 and in the sound box casing. The free end of the sty-y 4whichpermits the diaphragm tov vibrate by uy approved lus bai' 5 is enlarged to form a 'cylindrlcal .I

portion 6 which is provided with'an axial socket opening into the end thereof as shown and with Vop sitely extending rigid arms, rigld therewith, formed'by the transverse 4plate or portion 8. To the ends of these arms are rigidly secured by rivets or otherwise, .the outer ends respectively of two spring arms 9 and 10 which are connected at their opposite ends by the comparatively rigid fiatI portion "T formin l a Ushaped spring support for the stylus ar. The stylus bar 5 and its transverse arms or plate 8 are preferably made in one piece of metal so as -to be substantially rigid toimparta positive vibrator-y motion to the diaphravm.

The' U-shaped support for 'the stylus -ar is preferably made of s ring steel and the arms 9 and 10 are pre erably deflected in opposite directions before being tempered to assume the position shown in Fig. 11 and the support is then tempered uniformly.

When secured in place between the sound vbox casing and the rigid arms of the' st lus aralle inl iaphragm,

bar, the arms 9 and l0 are-held a plane perpendicular to the and under balanced stresses. n

For 'connecting the Ulshaped spring sup-- sideof the casing 'is flattened and is pi'o-" jvided with a plate 11 secured thereto, upon porti'igidly to the sound box casing, one

i intermediate portion 7 of the U-shaped suport by means of a screw 12 which passesl reely through the s ring support, washer 13, and plate 11, an is threadedinto the sound box casing. This construction holds -the intermediate portion 7 of the spring support in fixedrv position but permits the free elastic motion l'of its arms 9 and 10. .Each stylus bar is therefore free to oscillate Y 10 in a .plane Lperpendicular to its V'diaphragm 'comparatively rigid against but;` 1s hel movement in any other direction.

' rotatively and longitudinally adJustable crank sha ed stylus arm 14 1s secured 15 in the socket o the free end 6 of each stylus bar by a set screw 17, and the outer end of each stylus arm 14 '-is provided with 'a socket for holdin a stylusil, and with a thumb screw 15 or clampingthe stylusin 2() position. The construction is such that by adjusting the stylus'farms. 14 the stylus of one sound-box may be arranged Vto track closely after vthe stylusy of the other sound' .box 1n the same track or groove of the 'rec ord. so that the' two boxes will reproduce 'practically .simultaneously the same tonesV om vthe record.

For supporting the soundi'boxes, "a me# i tallic U-shaped tube 418 is secured at onee'nd in theopenlng inthe back of-thecasingof each 4sound boxby a driving ft,'and the other end of the tube .is providediwith a flange or collar. 19frigid therewith, provided' with a segmental stop plate 20 concentric 35andv rigid therewith, which nterlocks with a segmental` stop plate 21l concentric'and rigid with one end of a hollow T coupling 22. T e T coupling 22 comprises a transverse substantially cy indrical-tubular portion exi` A tending between the ends --of the'U-s'haped upon each end is threaded a union'collur 19 having internal Ithreads 24 vand whereby -the flanged ends ofV the U tubes are rotatably secured to the endsof the transverse portion of the T. r f A The T coupling 22 is provided' with a circular battle plate or defiector 25'arranged' transversely of the cylindrical portion ofthe T and 1n alinement with the axial plane;4

.of the conical portion of the T substantially perpendicularto the axis of4 the transverse.

portion Iof the` T. This detiector is prefereo ably integral with the T and tapers in thickness toward the conical portion of the T, the sides of the defiector being slightly curved.

The purpose of the detlector'25 is to direct the sound waves, coming from the sound 35 boxes through the U tubes18, into the lon-Q 4 tica gitudinal central portionvof the T and towardthe horn or sound'amplifier 26 which f is threaded into the outer end of the conical portion of the T.' The deiiector therefore transmits the full phonetic eil'ect of both sound boxes through a'single channel to the amplifier without an nullifying eiect of` one sound box upon t e othe J -1 The' 'T. coupling' 22 carryin the sound.,-

boxes and the horn 26, is rotata ly'supportFV 75 ed by a vertical post27 `which ismounted to rotate upon :1 -vertical axis in the upper end of a rigid metalarm or bracket 28 which is rigidly secured to the usual talking machine-f,- ca inet 29 -by any suitable means. The --80 cabinet 29 contains the usual motor for rotataf ing the usual turntable 23 which is mounted A upon the cabinet for'carrying a record. 30. By this construction the. sound boxes when in 'operative position, are arranged close to-g and facing'each other and substantially in axial alinement, 'and are Vfree to swing in unison across the` face of a record, or to be moved separately or in unison toward or j away from the record. The sound boxesare alsofree when in operative osition,to move either up, or down suilicien y to conform'to;

an unevenness in the surface of the record.

ennot in operative position on the recf ord, the sound boxes are supported by means 95 of thestopplatesv or projections 2O engag.v in 'with the "corresponding plates 21, and?. eit ier sound box may be inverted to rest in an ino rative position while the other sound box is eft in operation. 10o I,A1thoughv this invention has ,been here shown in only one of the forms in which it may be" embodied, it is obvious that many` 'changes might be made in the construction -h'erein setforth withoutdeparting from the 105 spirit of the invention, or the scope of the ap ended claims. l l l aving thus fully! described my invention, what I claim as' new and desire to se-` cure by Letters Patent is; 11o
