zFig. 8 is a section taken on the line 8-8 of Fig. 6, w ,7 g. 9 is a fragmentary section taken on the line 99 of Fig, 1, and

Fig. 10 is a section taken on the line 110-10 of Fig. 9. 1*. Referring to the drawings, 11 represents l'fi abox or cabinet which may be of any usual f: {construction including aturntable 12 which jean be operated by any suitable means (not -iillustrated) 2 support a record, such for example as the I record -l3 in Figs. 1 and 2 and the record '14 in Figs.,3 and 4. As illustrated the cabinet 11 includes a lid 15 which is hinged to the body portion 16 of the cabinet as-shown at. 17. A. post 18 is screwed into the lid 15, saidpost having a flange 19 thereon. The portion of the post above the flange 19 extends through a born 20 which is located 1 between the

opposite ends

21 and 22 of said :qj 'horn, as clearly shown in Figs. 1 to 4 inclu- I sive. A sleeve or bushing 23, which is pref= erably made of non-metallic material, such ;for example as rubber, surrounds the post 418 and extends through the horn 20. Thus rotate on the post 18 gf i-ng theho'rn at the proper. elevation. he horn 20has a transversely extending 'T-branch' 24 at the end 22, said T-branch forming afbearing for a tube 25, said tube extending entirely through the branch 24 and having an opening 26 (see Figs. 9 and :10) which. is adapted to register with the sound outlet passage 27 in the horn 20. .giThe tube 25 is V-shape in longitudinal sec ,"tion, as clearly shown in F igs. 1 and 3,

Fig. 3 is a view of similar naturelto .and the end 28 supports a sound box 29 in 1 showing my invention having been swung into a position for playing a record of'the Edison type; it merely being necessary to change the position of the reproducing a. position at right angles to. the axis of said lend portion. The post 18 is so positioned with-respect tothe center 30--of the turn- 1 table 12 and the end 28 and the sound box 29 diameter of the sound box transversely in-- tersects the grooves 32 ofthe'record 14:. The needleholder 33 has two

needle ducts

34 and 35 which extend downwardly at angles in planes substantially at right angles to each other as clearly shown in Flgs. 5 to 8 1nclusive. In order to play the Victor type of record, such for example as shown in Figs. 1 and 2, an ordinar reproduclng needle 36 is placed within t e duct .35 andsecured therein by a set screw 37 The needle 36 extends at the proper incline in accordance with-the direction of rotation of the record as shown by the arrow a. When it is desired to play a record of the Edison type, the sound box is swung into a position shown-in Fig. 3 at the opposite s1de of the center 30 and the reproducing needle 36 is secured within the duct 34 by the set screw 37 this position being clearly. illustrated in Fi s. 3 and 4. v

second horn 38. is adjustably secured to the opposite end 39 of the tube 25, said horn 38 having a branch sleeve 40 Which frictionally fits the end 39 of the tube-25; the friction between the branch '40 and the end '39 of the tube 25 being sufiicient to cause the horn 38 to swing when the sound box 29 is raised; itbeing noted that the tube 25' freely rotates in the branch 24 of the born 20. The weight of the horn 38 is such, when the latter is swung over the top of the tube 25, that the overhanging portion ofthe horn 38 will be sufiicient to hold the sound box in a raisedposition and the flared end 41 of the horn 38 will rest against the top of the horn 20 and the entire structure can be freely swung around the post '18 as a pivot.

By having the horn 20 pivoted between 'its ends the portion between the end 21 and the pivot post 18 will serve as a counter-balance to relieve the post 18 of any bending action. Furthermore, I preferably make the horn 28 of such length that when it is swung into a position holding the sound box out of engagement with the record that the flat end 41 will engage and rest upon the horn 20 at a position between the pivot post and the end 21, thereby also serving to throw an additional portion of the weight between the post 18 and the end 21. e

In actual practice and demonstration, I have found that by arranging the parts as above described in View of the difference in the characteristics of the grooves in the Victor and Edison type of record as.

above-mentioned that practically similar resultsare obtained in the two types of rec? ords and that the arcuate path of travel of I the reproducing needle toward the center is such as to properly engage the grooves of both types of record without cutting or in-' direction of vibration of the form shown in F1gs. 1 and 2 and in view of the position of the diaphragm in Figs. 3 and 4, these vibrations will also be transferred transversely to the width of the diaphragm, thereby giving practically similar results.

It will thus be noted that with my inven-Q tion it is unnecessary to change or alter the sound box or. the tone arm or any connecting parts when it is desired to change from one type of record to that of the other. It is merely necessary to insert the needle in one ortheother of the two ducts and swing the sound box so that the needle engages the initial groove at one side'or the other of the center of rotation of the record according to the type of record to be played.

While I have described my' invention as taking a particular form, it will be understood that the various parts of my invention may be changed without de arting from the s irit thereof, and hence li do not limit myse f to the precise construction set forth. but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, 8

what I claim as new and desire to secure by Letters Patent is 1. The combination in a talking. machine of a rotatable record support; a sound box;

and means supporting said sound box and 'movable in a path from a position in which the width of said sound box is in a plane substantially tangent to the curvature of the playing grooves, on one side of the center of rotation of a record, into a position in which the width of the sound. box is in a plane substantially transverse to the curvature of said grooves at the opposite side of the centerof rotation of said record; substantially as described.

2. The combination in a talking machine of a rotatable record support; a sound box;

and pivoted means for supporting saidsound box, said sound box being operatively supported on said means at a slant to the pivotal length of said means, said means being movable on said pivot in a path to present said sound box substantially tangent to the playing grooves on one side of the center of rotation of the record into a position substantially transverse to said grooves at the opposite side of the center of rotation of said record; substantially as described.

3. The combination in a talking machine of a rotatable record support; a sound box; and means supporting said sound box and movable in a path from a position in which the width of said sound box is in a plane substantially tangent to the curvature, of the playing grooves, on one side of the center of rotation of a record, into a position in which the width of the sound box is in a plane substantially transverse to the curvature of said grooves at the opposite side of the center of rotation of said record, said means including a horn and a tube connected to said horn and having an end portion extending at a slant to the length of said horn and to which said sound box is attached, said sound box having its width included in a plane extending substantially at right angles to the axis of said inclined portion of the tube; substantially as described. v

4.
