sou-nn-nox'ron TALKING-Meantime;

Be it known that I, LOUIS P. VALioun'r, a citizen of- New York city, county of-New -York, State of- New York, have invented certain new anduseful Improvements in- Sound-Boxes for Talking-Machines, (Case- A,) of which the following is a full, clear,

and complete disclosure.

The main. bjects of my invention are. to rovide-an improved sound box casing an proved mounting for a diaphragm and other 1m rovementsas will appear hereinafter.

I nthedrawings, Figu're'l is a centralvertical section -of-'-.a sound box 'constructed in accordance ruth th1s invent1on; F1g. 2, a

- 1- face'view bf -the same-with the cover thereof removed, showing the annular cushion of 111- sul'ating-material uponwhich the diaphragm is seated; Fig. 3. a similar view showing the diaphragm ,in position; Figie, a side elevation, partly in section of the stylus bar and its mounting, the sound box casing be ing' indicated. in dotted lines; and' Fig. 5 isan end elevation of the stylus bar. I I

Referringt'o the drawings, the casing of the sound box comprises a body member 1,

which is provided in the face thereof witha circular recess -2, forming a diaphragm chamber. Within this chamber and adjacent the front thereof, is provided an annular seat 3 for the diaphragm 4. The body of thelsound box is provided with a rearwardly extending tubular portion 5.v for connection with the usual amplifier. it cover 6, re-

: movably secured uponthe body of the sound 'seatof the cover, and projects within the disphragnr-chamber in close proximity to box by screws 7, se'rvesto secure the diaphragm in position. on its seat by beingpro-- vided with an annular bead 8, which is cast,

pressed,-o'r otherwise formed upon the inner the annular seat upon which the diaphragm rests. An insulating annulus 9 of 'no nsonorous material, such, for example, as felt, or fiber, .is interposed between the inner side of the diaphragmand its seat, and between the opposite or outer side thereof and the bead-ofthe cover.

This insulation is preferably applied .to one or more of the opposing faces in the form of anadhering coating as indicated in Figs. 2 and 3. The insulating material is caused to adhere by first coating the portion to be covered with Specification of Letters Patent. Application filed October 28, 1903. Serial No. 178,932.

a. suitable cement, and then dipping the which latter will then be taken up in sufiicient quantity to form an'efiective insulating cushion. In thus insulatingthe'diaphragm, local or sympathetic vibration is ed to the stylus from being transmitted to to apparatus now in gener use 1 proximately U-shaped 'lug 11, which a recess l2, forming the body portion box,ancl is designed toserve as a supp curves inward at its upper end and projects known manner, as, for exam le, by a hesive wax, or other material. T e opposite or lower end of the stylus bar is provided witha socket 15 for the stylus 16, and-the usual The mounting for the stylus bar comprises a pairof pointed studs 18, which project transversely from the bar, and which are seated in shallow depressions, or bearin U-shaped extension of the sound box cover; and which are equi spaced upon opposite sides of an opening 19 therein, through which extends the spring arm 20 for holding the bar in place. The spring arm 20 is in- .tngral with the stylus bar and projects subsiantiall. at ri ht angles therefrom, perpendicu ar to t e diaphragm and in the lane of the axis of oscillation of the stylus gether forming a substantially holder. This spring arm is reduced in cross section for-a portion of its lengtli,as-'indicated at 21, to make the bar sufiicieiftly' flex ible to serve, not only to hold the bar upon its bearings, but also as asprin'g to exert an influence upon the oscillation of "the bar. Beyond the reduced portion, the spring arm terminates in a threaded extensio'n22, which projects through an opening 23 inathe inner lug of the U-shapedextension, and is engaged by a nut 24; which contacts. with the The sound box cover at its lnwe edge is extended in the form of a'yielding al forhe stylus bar 13.- The stylus bar set screw 17 for holding the stylus in place.

10 a sufiicient amount of tension upon the spring arm for affecting a proper regulation of the Oscillation of the stylus bar to produce the best results.

- It is evident, of course, that various, changes could be made in the details of construction'shown, without departing from the spirit and scope of m invention. Other forms of spring might as the adjusting means therefor; the spring might be rearranged in its relation to the rigid arm of the holder and the same result obtained; but all such modifications, I consider merely unimportant variations of form n and still within the sco )e of my invention.
