To all whomz't may concern:

Be it-known that I, ALBERT A. HUsnBY,

a citizen of'the United States, residing at hic {inth'e dounty" of Cookand State ot gmmeis; have invented certain new and usefulfqmprovements in Universal Reprog-Machin'es, of which the following; is a specification. This invention relates to the art of talking machines. and'has reference more partucularl'y 'to improvements in reproducers which are adapted-to play records of both thelatera'lly and the vertically cut types. More specifically, the invention relates to that type of such reproducers wherein a singlejsound box is used, which sound box iscoupled tothe tone arm with capacity for a} swinging movement through an angle of ninety degrees (90), the sound box in one position being'adapted to play records of the laterallycut. type and in the other position being adapted to play records of the vertically-amt pie.

The object o the invention is to provide a simple, inexpensive, easily manipulated and im roved reproducer of the class specified.

he invention will be readily understood by those 'skilledin the a'rtfrom the following description taken in connection with the accompan ing drawing which illustrates one practice and workable embodiment thereof, and in which- Figure 1 is a top plan view of the swiveled section of the tone arm, the sound box, and the coupling'means, showing the sound 4 box in position for record.

Fig. 2 is a side elevation tion of Fig. 1.

Fig. 3 is a fragmentary top plan view, broken away, illustrating the other positionof the sound box.

Fig. 4 is an enlarged sectional detail on the line 44 of Fi 2.

Referring to the drawing, 5 designates the usual swiveled end section of the tone arm and 6 a sound box provided with the 'usua stylus lever 7 and siylus 8. The downwardly turned free en of the tone arm 5 is formed with a hollow boss 9 and with a circular external flange 10 surrounding the boss 9. This flange is formed with an arouate slot 11. 12 desi ates a coupling memher that 'forms in e ct an extension of the playing a laterally cut partly in sectone arm, being swiveled on the boss 9 and provided with a circular flange 13 that registers With'the flange 10 of the tone arm and 'is also formed Wlth an arcuate slot 14 similar to the slot 11. At its other end the ing this stud is a coiled compression spring 16 thatrests at its lower end on a washer 17 lying next 'to the slotted portion of the flange. Surrounding thespring is'a cage or housing l8, the inner end of which rests on the washer 17 while its upper end apertured for the passage of the stud and is engaged by the head of the latter, as clearly shown in Figs. 2 and 4. By this means the two flan cs, 10 and 13, are held in register, and at t e same time are capable of arch; tive turningmo'vement about their. common axis to the extent permitted by the slotsof the flanges, which latter are substantially ninet degrees (90) in extent. 'Thefianges are e astically held to ther with suflicient friction to secure the dx in either playing position. Figs. 1 and .2 show the osltion for playing laterall cut records suc as the Victor and Colum ia :rtcords;

rasping the sound box and turning it t rough an angle of ninety degrees from the position shown in Figs. 1 and 2, it is brou ht into correct position for 1playing vertica y cut records such as the records.

The described construction and cheaply manufactured, ,is reliable and eificient in operation, presents no obstruction to the sound waves passing from the sound box through the tone arm, and is neat and unobtrusive in apipearance. While angularly shiftable soun boxes coupled to. the tone arm are known most of them are either too complicated an ex ensive to be practican easily cable, or yield an inferior tone efiect when,

playing one or the other of the two types fill? record. M present reproducer plays b0 records wit equal efliciency, and mvolves no manipulation of the parts in shifting from By simply dison and Pathe stu one playing position to the other beyond a mere turnin of the sound box on its pivotal axis at the as end of the tone arm.

Without limiting myself, therefore, to the precise details shown and described,-

I claim:

1. The combination with a tone arm having a circular flange at one end, and a sound box, of a coupling member formin an extension of the tone arm and secure to the sound box, said coupling member having 'a circular flange registering with the flange of said tone arm, and means engag' and holding said flanges in register wi capacity for a relative turning movement about their common axis.

2. The combination with a tone arm having a circular flange at one end, and a sound box, of a coupling member forming an extension of the tone arm and secured to the sound box, said coupling member having a circular flange registering with the flange of said tone arm, and elastic means engaging and clamping said flanges together but permitting a relative turning movement thereof about their common axis.

3. The combination with a tone arm having a circular flange at one end, and a sound box, of a coupling member forming an extension of the tone arm and secured to the sound box, said coupling member having a circular flange registering with the flange of said tone arm, one of said flanges having an arcuate slot and the other flange carrying a headed stud extending through said slot, and a 5 ring confined between t e head of said and said slotted flan e.

4. The combination wit a tone arm having at one end a circular flange provided with an arcuate slot, and a sound box, of a coupling member forming an extension of the tone arm and secured to the sound box,

said coupling member having a circular flange registering with;the flange of said tone arm and also provided with an arcuate slot, headed studs carried by said flanges respectively and each extending through e 810 of the other-flange, and springs confined between the heads of said studs and said' flanges. l

5. The combination with a tone arm having at one end a circular flange rovided with an arcuate slot, and a sound x, of a a coupling ,member forming an extension of the tone arm and secured to the sound box, said coupling member having a circular flange registering with the flange of said tone arm and also provided with an arcuate slot, headed studs carried by said flan s respectively and each extending through fie slot of the other flan e, springs confined-between the heads 0 said studs and said flanges, and housings surrounding said relative turning movement about their oommon axis.-

ALBERT A. HUSEBY.
