smaller end of the horn 13 is reduced externally in diameter and fits snugly. within theY upper portion of the rin 6.

A tapering tubular seundrox arm or tone' In the accompanying drawings Figure 1 is aside elevation of a talking machine emarm 14 is provided, which has 'surrounding bodying this form of 'my invention. Figs. its larger end an 'outwardly extending ange 2 and 3 are views villustrating details of 15 exteriorly in the form of/a spherical zone construction, certain parts being' shownin which Iits loosely` within the `cylindrical section. Y opening in the lower end of the rotary collar Referring' to the drawings, one embodi- 12, and is pr Qvided withdiametrically'oppo.-

, itsends i a vertically Qwardly extending yo e i' 3 zoritallyl therethrough, the screw ofeach armbeing .spaced :,al'inement collar iment of "this invention comprises the 'usual 'casing 1. whiehcontains the usual spring motor, or other actuating mechanism, which is connected by a vertical lspindle extending .through the top of the' casing with the l usual horizontal turntable V2 arranged above the casing. p' e" Attached eXteriorly to the rear vertical wall of the casin 1 and extending laterally and upwardly therefrom isl a brack or support 3 whichis provided intermediate with a vertical opening 4 extending vtransversely therethrough.4 The upper porthe bracket curves inwardly anc terminates in a fixed horizontal ring or co1- lar 6 which may be integral therewith.

Within the opening 4 in the bracket 3 is adJustab e 'pin 7 which is hel rigidly in osition within the opening by fmeans of a set screw 8. The upper endo the pin 7 is'in the form of a conical bear# ing V9 which engages the lower end ofan upk '10. Each of the two site sockets in the conical inner ends of the screi"7vsi1,1;` Each ofthe screws 11"is provided outside of the yoke with anut 16 for locking the' screw in position with respect to the yoke.

The smaller end of the tone arm is pro- -vided with the usual or any suitable sound box.,or sound reprodueer l17,-which is ar ranged to coperate with a sound record carried bythe turntable 2. f

From the foregoing description, it is evident that in this construction the smaller end of the tone arm together with the 'soundbox 17 carried therebyv maybe moved freely vertically, the `spherical tiangeY 15 of the larger end of the tone arm moving easily within the lcollar 12 on a' horizontal axis about the conical ends of the screws 11, and4 also that the 'ree end of the tone 'arm an the sound-box carriedthereby'maybe moved -freely horizontally across the record support, the collar 12 turning freely `ring 6, together with the yoke 10, about' a vertical axis coincidentwith ring 6 and with the longitudinal axis of the pivot 7 j This eonstructionprovides a continuousunobstructed and practically soun tight conduit from the sound-box 17 to the amplifying Ihoin 13,- which is 'free rom sharp kcorners and- .through which sounjd waves may be transmitted without being' divided or modified in `any manner uby ins, cross-bars or other parts such ashave een used in some instances arms of the yoke lO'is provided adjacent its upper end with a screw 1 1 threaded horirom and in' .longitudinal y with the screw of the other arm..` hese screws 11 proiect diametricaliy"--a through the opposite walls respectively of .i 12.

The collar 12 is arranged coaxially with the xed ring or support 6, the upper portion of the collar being reduced in external and internal diameters and telescoping roheretofore and which the axis of the'4 which yengages respectively within the fixed will allow' the sound waves to proceedl 11'0 l with a sound conveyin tube, of a substantiallyv cylindrical mem er Awith which said tube telescopes, a support carrying said member,y said support and member being movable about the axis of the latter and of said tube, and pivots for said tube extendingwdiametrically from said cylindrical member.

2. In a' talking machine, they combination with fa hollow sound conveying t-ube, of a collar within which sid tube fits, a yoke supporting said .collar and tube, said yoke,

collar, and tube having devices which con-y neet them together, so that said tube is pivotally retained in posit-ion, and a support having-an opening therein'within which a por- Y ber connecting said collar to said end ofsaid tion of said collar is retained.

3. In a talking machine, the `combination with a hollow soundv conveying tube, having VV*"a flange at one end thereof, of a collar having a cylindrical opening therein, within 'which said iange lits loosely, a yoke pivoted to turn on a vertical axis, said yoke havin pivot screws which pass therethrough, an through said collar, and engage said flange 4o pivoting lsaid tube upon a horizontal axis, and afixed support having anopening with inwhich a ortion of said collar fits.

4.v In a talking machine, the combination with a hollow sound conveying tube, of a collar which telescopes with one endo-r` said tube, a yoke, pivot devices carried by said yoke, and engaging both said tube and said collar, forming a bearing to permit said tube to turn on a horizontal axis, a fixed' support 50 having an opening therein'with which said collar telescopes, and a vertical` pivot for said yoke. l

5. In a talking machine, the combination with a hollow sound conveying tube havin a spherical fian e at one end thereof, a co llar lwithin whic said flange fits loosely, a yoke pivoted to turn on a vertical axis, set

crews passing throu h `the ends of said yoke' and through said colar and engaging Suid flange, pivoting the same upon a bafaontal axis, and afixed support telesqing with said collar. ,6- l a falkmg machlne, the combination with a lhollow s oundzt'onveyin tube, of a e5 collar with whichfsaid tubev gelescopes se 'as to prevent the escape of sound waves, a

yoke or. sup orting said collar, said yoke, collar and `tu e having devices which connect them together plivotally, and a" support having a'nopening t erein, said support also 7nV adapted'to telescope4 with said collar. l 5
