Sci-rnp wn'rfrumacitien of Austria, and a subject of Kaiser Francis Joseph, residing at Cleve- 5:la'nd, inthe county of Cuyahoga and State Y ;o:f.-hio,jh:nfe invented some certain new and '.1 useful Improvements' in.Phonograph Sound- ,.-xBoXesg'and I.do` hereby4 declare the followiing 'to'fbfe'fa`:tull',clear,` and exact description -j.lo'of'ithe'invention, such-as Will enable others ndjhse the saine.t

- providing also means `such as tubes'leading from said sound boxes respectively, to which f may Jbefat'tached horns if found desirable.

manner of connecting them togetheraud the '40 construction of intercommunicating tubes,

all of which will be hereinafter fully set forth and claimed.

ner-.tionV 9, the stylusf holder 10,1:Which is toi'nis part of said stylus 'holder 10`,-`and 'are' connected therewith, the same bein supported by means of the screws a. b. or 'adjusting purposes. The stylus holder 10, isv provided with a bearing surface c, which rests against the knife edge d. These bearings being adjusted and brought together through the medium of the screws a. b. Thus it will be seen that the mounting of the stylus holder is such that While it has a tree vibratory action, it follows the characters on the record in consequence of which movements are imparted to it through the stylus, and all rattling, scratching or play movement are obviateci. The metallic parts phragm 3", mounted iii-close. proximity to@ that vmove in relation to each other are the knife edge d on the surface c. This obviates fas :it-will be' understood, all foreign sounds 'or scratching which would attend as a discord, and also provides means for imparting #to the diaphragms the most minuteV varia- 'tions or pitch of tones.

I now come to the manner the multiple sound box, which is as follows: -The several branches 6', 7', and 8', of the tubes 5, 6, 7', and 8, are swiveled to the tubes 5", 6", 7",-and ;8", in such a manner that the sound box will raise. and lower with theA variations of the record surface, always tending by the partial Weight of the sound box to keep the stylus 11, 1n contact within the grooves. of. the record.- However, in'l order 'that the sound box ma partially be supported should it be too e'avy so as to wearupon the record through the stylus 11, I have provided a spring 12,. which may be 'made adjustablefor supporting the sound box through one of its branches, in this case This spring supports athe branch tube 6'. portion of the weight of the sound box, but

Aat the same time allows of sufficient pressurel -for the proper reproduction romthe record.

' Thesections 5", '6", 7", v8", are telescoped'into tubes 13, 14, 15, and 16, in such .a manner vthat the sections 5", 7 and 8", slide freely Within the tubes 13, 14, and- 16. Thesection 6" being held in predetermined adjustment in relation to its tube 14,

by means of. a screw 15, as the stylus with its sound' box travels along the face of the record, toward the center of the same, the

' section 5", moves inward within tube 13, and the sections 7", and 8", slide outwardly.

with an :adjustab The-fitting ofthese joints is such that no appreciable sound or scratching results from the movement in relation to each other. In the movementY ofrthe stvlus with its .sound box toward thecenter of the record or from one sideto theother. of the record, itis of course essential that the arms 13, 14,15 and '16, have an oscillating movement or swinging movement in ahorizontal plane, and for thls purpose I have mounted the several sections 13,`14, -15 and 16-as illustrated in Fig. I, of the drawings, by providing the same e center screwv 17, resting 'of mountingl in the step 18, and also by forming the u per" end 19, ot the several sections with a bal set. 20, which engage antifriction balls 2l, in a race-way formed in the under side of the vertical -journal 22, which in turn" forms part of or is'secured to arm 23. This allows of a freenoiseless movement of the several sections lh-14,15, and 16 in a horizontal di-v` rection, and provides a convenient means for assembling and taking apart the several portions of the machine. 'At the upper end of the journals 22 I provide sockets such as 24, for the reception of the receiving ends of the several horns 25, 25, allowing these horns chambers foreach individual sound conveyin tube and horn. Vhat'I claim is:`

Y A reproducer for sound waves comprising a sound box,4 having end and intermediatechambers separated by partitions, tubes extending into the end-chambers and oonto be swiveled. or turned in any desired. di-

nected toeach partition and other tubes coni f nected to the ends of the box, diaphragms located inthe chambers, opposite the ends of the tubes,l afiexible connection between said diaphragms. and extendin through,` openingsinthepartitOnS, an a stylus operatively connected-to said connectlons, in the intermediate chamber.
