One object of my present invention is to avoid the necessity of removing the stylus i as is required in the machines now in use, by providing an im roved stylus formed. from sheet metal and aving a plurality of closely-aneuged reproducing I nstructed, and a new reproducing point brought into operative position by a slight rotary move. ment of the disk. i

Passing through this bushing is a shaft 17 provided at itainnerend with a cone bearing 18, and its outer end with a removable screw-threaded adjustable cone-hearts? 20, the-said conearm s resting m a engaging the coneshape bearings 21' and 22 of the said bush" in whereby the. shaftis free to oscillate. rejecting from one end of this shaft is a plate 23- .rigidly secured thereto, and this id upwardly extending erred to. Said plate 23 portion 24 to which is connected a stud bearmg'e's extending from the late in the oppo l 7. My improved stylus 26 is rotatably mounted upon the stud '25, and this stud, it will be observed-,extends in a direction parallel with the shaft 17 and in a direction which is tang'ential'to the circle described bgr the wavegroovesformed the disk reco'r This im- --proved stylus is fiiade bystainping from thin =sheetmetal, in disk-like form, and its flexi- .bilit'yiiii-a; direction at right angles to its face is'increased byforrnin it with the radiallyxtendin spokes 29 outer an s to a flat rirn 30, and this rim has {oi-med integral therewith a plurality of outwardly-extending needle or reproducinlg oints' 31, though the number maybe varie ttention is directed to the fact that for the- .pu rpose ='iof insuring the rigidity ,of these points in a directio' the disk, they are in ends, and

d'isk-likestylus is mounted to be capable of rotation 'ina directiouoorre- 6o wave grooves operation, for sound producing against such rotation by means of ccives the screw-threaded For convenience th1s-scre'w-threaded ing arm 32 which has 33 which is pivotally connected to an car 35 carried by t a plate 23 through the medium of a pivotal bearing 34. In this way the stylus', though mounted to be capable of rotation to successively bring the several oints into operative osition, is nevert eless clamped sufficient y firmly to the arm 23 to cause it to be rigid therewith for the purpose of the record to the diaphragm of the sound box, and as before stated, the stylus itself,

because of itsconstructi'on, is rigid in the direction of sound-wave deflection, so that none ofthe delicate, fine'sound waves can be lost by flexibility, but are positivel conveyed to the sound boxdia ,-w 'le at the same time the stylus is dbxil fi tion to Kield to'the oughness and unevenness of t e bottom of the sound-wave grooves this roughness to the sound-diaphragm.

is found to'beof great practimlu'tility in the softenin of the tone of the in avoi' ing the usual sound" common in sue practice these gether as p0 instruments. In

In a device of this character it is essential that when the stylus is turned to bring any one of thereprod'lieing points to operative position, it must'be-accurately turned the proper distance to prevent anyof the other points interfering able this to be quickly, readily and accuprovide means for turning the stylus one oint at a time. This consists of a lever 40w ich extends through and is journaled in the blocklO, the end thereof adjacent the stylus being provided with a crank arm 38 carrying a laterally-extending pin 39 ada ted to elegage between the points of .the nee is when the handlc'is rotated. In the position. shown in Figs. 1 and 2 this handle is portion of the stud the'wave-sound inundations In practice, this instrument, and. grating or grinding member 36 is rotatably' mounted in a'swinga laterally turned ear in a direc-- oints are placed as near-:to-

To en- I 111 its; inoperative position, and has'its handle I end in frictional engagement with the edge or periphery of the sound. box to hold it in this ositionand out-of'engagemcnt with the styus. The crank arm pin or stud 39 will engage hat-wean the points of the stylus when the lever 40 is rotated, and asin'glc rotation thereof will cause the stylus to be rotated a portion having a circular ing ofa plurality of radially-extending vantage in the hands right angles thereto for what I consider at this time the most desirthe rou distance to bring a succeeding point into proper operative position in respect to. the record. I

As previously stated, although the stylus is capable of rotation to bring the points thereof into successive o eration, it is clamped sufliciently'tight to e rigid so ,far as transferring the inundations of the sound waves to the sound diaphragm is'concerned, and this frictional clamping of the stylus assists in the positioning of the points by pre venting it from'throwing by or beyond the distance it .is actu llymoved by the crank arm pin 39.

A stylusof the construction here. shown will avoid to a very large extent what is considered by many to be an objection to that class of instruments which require the remo val of the stylus and the substitution of a ,-new one for each tune, and will place this ad of the-user at a considerablereduction over the cost of using the ordinary single needle, and this is due to the tthat the K rmed from thin sheet metal capable of be,- ing "produced by stamping y it therefrom, vi -hile'atthejsarne time :it has the advantage yof rigidity in the proper direction to avoid the lossjof anyof the delicate sound waves, and 'fleXibilit" in the direction liness'and irregularities of the bottornof. e wave grooves;

I am aware that flexible needles for sound producing machines-of. the character herein escribed have been heretofore devised, but sofa'r asl' know these need been xflexiblef iin all-directi there wouldof necessity be some loss in conveyin'g the delicate'soundwayes to the sound 1fthe flexibil ty .of the needle gs'orstvluses have is constructed to be inft eodire'ction of deflection-of the sound waves, and flexible in a direction at the purposes hereinbeforeex lained,
