To all 'icfwm' it may concern." f Be it known that i, Joris A.

needle may be quickly end easilypositioned with respect to the grooves of the particular type of disk to be played without moving the tone erin and without displacing f the sound box bodily with respect to said arm. Another object of the invention is to multe it possible to secure such adjustment without modifying eppreciably the usuel form ot' tone erm and by making the adjusting devices between thelatter and the sound box of simple and inexpensive character. Still another object of the invention is to permit an adjustment of the che ucter described without displacing the needle itseit through en appreciable distance, the movement oit' the sound box'with respect to tie. tone erm telting place i'ibout an exis which is nearly coincident with the exis ot' the needle. A'iurther object is to improve the construction of tone :irins for griipliophones by providing e simple and eii'eetivc pivotal joint therein whereby the outer end of the erm with thel sound box may be readily swung in u vertical plane when the needle is lifted ytroni therecord. Other ob- 'l Fig. 2 is a view in' plan of the devices' illustrated in Fig. l, partoi:` the tone erin bein broken ewav to show in horizontal I i9; c a

Fig. 3 is'e fragmentary view indicatingl u. portion ot' the tone firm and showing the sound box in e position et 90 to that shown in Figs. l and 2 to permit the reproducing,r

ot vibrations caused by e laterally undulzitingl groove.

Eig. Il is :i view in side elevation showing the sound box illustrated in Figs. l und 2.

Ellie improved tone erm comprises generelly e main section a formed as an elbow and edepted to have pivotal engagement with any suitable supporting devices, indilill() cated generally at 2', and a second section like, by forming the inner end et the section a with hemispherical bearing surfaces which rest snugly within the mouth ot theelbow section a and conform to thecurvature thereof. lf desired, provision may also be made, 1n the form ot a springlateh o7 carried on the upper tace of the elbow a' and. adapted to co-act with a fixed nose c3 ,formed integral with or mounted on the upper face of the second section o ot the tone arm,'or maintaining this last named section in elevated position with respect to the elbow when the sound box and needle are lifted from the record. lhe engagement of the latch ci with the nose al", is, ot course, yielding, and the engagement and diserr gagement therebetween eii'ected readily by pressure on the second section c' of the arm.

The outer section a of the tone arm may be :formed either in a single piece or may be made up of a plurality of sections as illus trated in the accompanying` drawings. For instance, there is indicate as at c, a short removable section intended to be eng-aged with the straight section c in any suitable l manner, 21S through a bayonet joint, shown at f. This short section e has its inouthgin clined generally downward, say, at an angle of abouto, and is formed on its upper surface at a point substantially co-incident with the axis of the downwardly extending pon tion referred to, with a recess e' in a knob e2, for a purpose which will appear later.

The improved sound bon g, in the preferred frm, has its rear wall formed with an ,opening y and a generally circular flanged mouth g2 of such outline and dimensions as to receive snugly the mouth of the straight section o olf the tone arm. The rear wall of the sound box g and the cylindrical mouth g2 thereon are preferably formed with a continuous shoulder g3 against Awhich the lip of the section. c rests when Athe tone arm and sound boX are in their normal relationship. The rear wall. oi: the sound bon g is also formed adjacent periphery and preferably at a point substantie" di cally opposite the needle It, i, i rearwardly extendingI bracket it through which passes a thumb screwv c", the point of which is preferably tapered and rests in Athe recess c of the bearing c2 on the short section c.`

From this description it will be evident that when the thumb screw c' is set up lthe sound box g will be drawn bodily upward so 'that the lip of the short section e will loe locked in frictional engagement with the shoulder Saga 1 y movement. .ln realisncipal ebiects oi the applicantls it is desirable that the thumb screw iouldhave its axis as nearly co-in c i the asis ot the needle o as poswith at all events,I have its axis with asis off the downwardly extend nouth oll the section a. of the tone arm, that is', in the illustrated embodiment, coincident with the artis of the downwardly extendingmonth oit 'the short section e. ln this 'way the sound bon may he rotated bod l siiipport allor/ded by the the position shown in @les with respect thereto, As has been en plaine@ e, non the sound bei; is in the position .in in Figs. l and l?, 'the needle will reproduce vibrations caused. by irregularities in depth ol a groove oi' truly spiral form, while, when the sound een is in the the needle will larities scope ofthe appended. claims not de y in'vtnition i l. ln a talking machine, the combination oi a tone arm including a downwardly in clincd section detachably secured to the end thereoi", a sound. box provided with a lip'to receive the mouth of 'the inclined section,
