My inyention re ates to, talking machines loand has particular reference to a mounting for-the tone-arm thereof. In such machines t isord narily essential that the tone;arnr..have .freemovement n vertical and hori aintal-.planes. ancl the purpose of' ;,the' pres'e nt invention 18 toproduce anextre'melysimple and inexpensive form of mounting which will permit such movement 'of: the"tone armand reduce friction to a provide fol-readily removing the tone-arm or placing thmsa'me in position, without requiringthe aid of skilled workmen or tools, thus facilitating packing, shipping and ascscmhling the machine foruse. A further object is to avoid the neces-' sit for careful and accurate adjustment. of parts in mounting the arm and produce a cmistructlonin which confusion or mistake in assembling will. be rendered improbable notilnpossihle and the parts will be self adjusting. when brought into operative re-- lation w th-each other. i

however, that I do notlimit myself to either' the exact form or details shown, as various changes maybe made within the meaning -of the present invention. I I
In the drawings--Figure 1 is a view in elevation. partly in section, showing the invention applied to 'a talkihg machine of the 5 concea'led horn-type. Fig. a section on the line 8 -5 of Fig. 1. Fig. 3 is a similar viewon'the' lineS-S of Fig. 1, Fig. 4 a verticalsect-ional new illustrating a modi l TALKING-MACHINE.

I At the rear or larger end, thMtone-arm js 6 5- giventheiapproximate form of a portion iofjfi a sphere, asindicated'aLS and loosely en? circling the shaped-end, there is a9; which is secured thereon by two screws The screws are arranged diametrically opa'lo.

As shown, the screws are threaded in the ring 9 andprovided with rounded or conical hearing points which enter 'correspondingly formed recesses in theshaped end of the tone-arm. V w
It will he observed that in assemblin'g the ring and arm, above described, the
straight surface of the'ring is cooperatively presented to the spherical surface of the tial relation of the parts, contact is rcduce'd 8 5" t'o 'a'mere theoretical linethus doingaway p with all friction. In order now'to provide for free horizontal movement of the was. :"111, the ring 5) is exteriorly threaded, as
