ToaZZ whom; t Mag/' ccinoern: -i i Be it known that I1, Louis LUMIERE, a citi' zen of the French Republic, and residing .at

262 Cours Gambetta,.Lyon, France, have-in'- vented certain new and use ful lImprove-- ments in and Relating to Talking-Machines,

f: This specification relates. to improvementsv in talking n'xachines,y particularly' vto that type .of talking machine illustrated-11n and Patent of the United States, No.1986f477,

dated March 14,1911, special-.reference bel; ing had. to the construction, illustrated' in- Figure 1 0 of said application. Myv invent-ion" has for itsV object,

stylus With-the diaphragrrn?.

y A further objfct of construct. the connection kbetween thestylus 2 and the diaphragm, particularlysfvslien''dia phragms of large diameter; are ,employ/,edi4

fully without beingfzsub'jec'ted; tot any :torfV sional ,or other-:.strains, due tothe'fact' that,

, the diaphragm is attached to.. -a stylus bar,l

such as are illustrated-in m above! nnenf` tioned applicatiomtha-t the saiddiaphrag'ms are' permitted 'tol and'4 will. vibrate freely and attachment ofthe stylus with the diaphragm Wil not vibrate any other manner-than in :a line substantially i1ormal*to the aplane of thediaphragm. j.. ff? 1 In carrying out my invention, 'I make the connection between;l the stylus and ythe i diaj phragminsuchfa' manner'- that the 'dia-, phragrn is :locatedl substantiallyA parallelwith a disk record?, and I" provide such a con- 1 nection4 between fthe, diaphragm o, andiy the] pointof thelstylius that by simply turning the soundbQXQthrough a right angle in the .plane of #thediaphragm,l the'` sound boxy maybe used with.' both of the 'common types' ofn disk records; 'thatff is; to' say,` withv disk recordsy in ,Which the. sound AWaves are .re-

l'corded in the Vform-of agrfoove', the bottom r 'of Whichvis providediwith. vertically ar-v ranged undulations corresponding to sound' groove of' substantially n iniform depth bu provided f with lateral," undulations in th tof-Pf6?? videlimproved-rmeans for connectingthe 4ofwhlch r1s connected by a direct connecting ja record such as is above described, having lmanipulation ofthe sound boxtocoperate ,diaphragnn illustrated the drawings of this application, and the construction con- :sists 'of a'bell'crank lever, one arm of which i is' provided -Withmeans whereby the stylus maybe attachedthereto, and the other arm bar with ythe diaphragm, the said connecting the bell crank-lever-bymeans 'cfa' fiexible gorfy yielding connection. From the above it will be seen-that the disk record issubstanthefbell crank lever and thediaphraginis rectionthan in a line normal to the plane ofl pear-in the specification and rlaimsbclow ed Aug. 2o, 1912,.
