THE AEOLIAN COMPANY,

WESTFIELD, AND EDWIN SCOTT VO'I'EY, or smnfl'r,

A CORPORATION OF CON ruonoemm AND run an.

To all whom it may concern: v

e it known that we, HENRY Bnnnns TREMA NE and EDWIN Soorr VoTEY, citizone of United States, residing, respectively, at Westfield and Summit, New Jersey, have invented fointl'y new and useful Improvements in honogra'ph's and the like, of which the followin is o specification.

Our inv nt on relates to improvements in )h'onogfhphs and the'like and more perticir iarly to means which readily permits the instrument to be used with any one of a pin-- rality of sound-boxes. This permits the rec yinterchange between sound-boxes of both the hill and deleand lateral cut record types and between diflerentsilzes and qualie ties of sound b'oxes of the seine type, also the same ready interchange between tone a'r'ms appropriate to the several sound-boxes.

In the drawings, Figure 1 is a fragmentery vertical section ofa phonograph showing our im rovements in side elevation, the

' section being taken on the line 11 in Fig.

' arm may and the tone-arm's should be 2 looking in the direction of the arrows,- Fig. 2 i epl'an view of the same; Fig. 3 is an enlarged detail of Fig. 2; Fig. 4 is a verticol section partly in elevation on line L in Fig. 3 looking in direction of the arrows; ig. 5 is a vertical section partly in elevation on line 5-5 in Fig. 3 looking in direction of the arrows; and Fig. 6 1s a. detail view of the lower portion of Fig. 5 seen from the left.

Describing now the specific devices of the drawings, '1. indicates the usual cabinet, 2 the top shelf, 3 the motor spindle, l the record turntable, and 5 the neck of the horn.

Our invention provides two tone- arms 6 and 7 and two sound- boxes 8 and 9. jThe sound-boxes will-diiier in size or character appropriate thereto. One kind of sound-box and tone:

the ordinary tonear'm and sound-box to the record.

Describlng'now the details, 10 is a stationl'atc having a central opening 11 locht'c over the neck 0% thehorn. 12 is a,

stationary upright member having an over- S'peciflcatlo'n of Letters Patent.

be adapted to certain classes of: records whereas another may be adapted to Patented De'cl 4.19111.

hon ing portion supporting a bearing in 13 1g. 5) concentrically over theopemng 11, said pin being spring pressed ddwnwardly by the spiral sn'ing 14. i 15 15 are a pair o f rings surroundi the bases of the respective tone-arms, e'ac' ring being inw rdly flanged to overlie the flanged base 16 of it's tone-arm with a rotary bearing fit. Each ring has anintegral flat lug 1'? by which it. is pivoted to swing in face contect with the 'p'lat'el'O. ,The pivots 18 are positioned '(co'inpere ig. 2) so that each rm can be swung into a position which will firing its tone-arm over the opening 11 in the o the horn, in which position the pivot pin 18 snaps down into the recess 1'9 (Fig. 5) in the shoulder of the tone'arm and thus forms an upper hearing about which the t0ne-arn1. can pivot as it swings with the sound-box across the face of the record.

To give additional rigidity at this time to the lower bearing ring 15, I provide another sprin".pressed pin 20 supported on the plate 1 and positioned tosnap into a recess 21 in the outside of the given 15 when in its playing position ShOWil in Figs. 3 and 5.

Fig. 2 shows the left hand tone-arm and box in pla ing position. Should thenext record to e played make it desirable to, change to the right l1cnd-sound-box and lIOIiG-flllTl, this is quic ly accomplished by grasping the basal end of the tone'erm 6 (Fig. 2) and pulling it toward the left which movement wi 1 force the spring- pins 13 and 20 out of their recesses and thereby release the parts so that said tono arm 6, and its ring 15 can be swung into the'out-of-the-vvuy position hownby the dotted lines. It is eqilally simple to bringthe other tone-arm 7 into ple infi position by ushing it end wise to the is t in Fig. 2 until'its bearing i1ng 15 snaps into engagement with the pin on, whereupon the sound-box can be ML Justed into playing position on the in the usual manner.

What We claim is:,

1. s'oqnd reproducing or recording machine having a horn, a plurality of tonsarms, a support havin dent with the openin ending to t e horn, and a plurality of r ngsenchfcrming' a lower bearing for one of the tone-arms, each ring having o connection with the support by a screw 18 plate 10 and the neck 100. record permitting it to be swung into and out of registry with said opening-to the horn.

2. A sound reproducing or recording machine having a horn, a plurality of tone arms, a support having an opening coincident with the opening leading to the horn, a plurality of rings each forming a lower bearing for one of the tone-arms, each ring having a connection with the support perm-ittin it to be swung into and out of registr-y Wlfil said opening to the horn and automatic means for releasably locking each of said rings in'its said position of registry.

3 A sound reproducing or recording machine having a horn, a plurality of tonearms, a supporthaving an opening coincident with the opening leading to the born, a plurality of rings each forming a lower bearing for one of the tone-arms, each ring having a connection with the support permitting it to be swung into and out of registr'y with said opening to the horn, and a pivot pin supported'over the openingvto the horn, arranged to releasably engage and constitute a bearing for each tone-arm when its ring is in position of registry relatively to the opening to the horn.

4. A sound reproducing or recording machine comprising a horn having a single neck opening, and a plurality'of tone arms,

either ar n being movable at the horn end into and out of playing position relative to said neck opening to the exclusion of the other arm.

5. A sound re roducing or recording machine comprising a horn having a single neck opening, and a plurality oil-tone arms, any one of said arms being movable bodily relatively to said horn and exclusively of the other arms into playing position with respect to said neck opening.
