To (ll? whom it may concern:

Be it known that I, Fnaxcnsco CIRELLI, a.

citizen of the United States. residing at Phil-.

adelphia,-in the county of Philadelphia and State of Pennsylvania. have lnvented certam new and useful Improvements in Sound-Reproducing Machines, of which the following is a specification.

My invention relates to improvements in sound reproducing machines the object of the invention being to provide a machine of the character stated which dispenses altogether with the ordiinar horn, which may be readily carried from'place to place, and occupy but relatively small space.

A further object isto provide an lmproved construction of box in which the sound waves are directed by a tone arm into a chamber havin perforated walls located at one end of the 01;, leaving a chamber at the other end, or front portion of the box, for the turntable and recorddisks.

A further object is to provide a sound reproducing machine of the character stated which provides a drawer for the accommodation of the tone arm and sound box when disctmnected from normal position, and per-' mits the assemblage of record disks on the I turn table where they .can he conveniently supported when the machine is to be moved fromlace to place.

Wit these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims. U i i In the accompanying drawings:

Figure 1 is a perspective view illustratmg my improvements. j I

Fig. 2 is a view in longitudinal section.

- Fig. 3 is a view in transverse section,

s Fig. 4 isa view in section on the line 4-4 of Fig; 2, and Fig. 5 is atfragmentary sectional elevation showing certain of the coupling parts in register with each other.

.1 represents my improved box, and 2 a. hinged cover thereon. The box 1 1s to contain any: improved motor (not shown) and asliding drawer 3 is provided in oneend of the box which is as deep as the space will allow. "A horizontal platform 4: is secured in the box 1, and spaced from the upper "edge thereof -Acurved wall 5, extending transversely of the box l, supports hOIlZOIIk I tal removable plates 6, .6, which together sonnn-nnrnonucntro Specification of Letters Patent.

. ing chamber 9. The wall Patent withthe wa-ll 5;constitutes perforated as shown at, i to escape in all direction ifedkiooivet 2 whensupported in open H mihytli supporting member 8 actisras .h-ilddfieotouWt sound board to throw the sound* tardthe i" front end of'thebox. p

In the center? of the sbund a utiimg chamber, a collar 10 is: supported ma vated above thebottomwofietheiri ohamher that the sound waves.'canmitreeljit pitgsn'i'ndio ilt" the chamber. This collars1 0- te nfls mbm m 13 permitthe projection 14 space within said coupling; turning the coupling ring "1 rectionfrom the position shown'in Fig. 5, the recesses 13 will be moved outof reglster with the projections let andthe rejections 14 will thereby be confined with n the coupling ring and prevent the tone arm from eing moved out of its proper relation with the collar 10.

It will be noted that the outlet end of the tone arm is enlarged and that the upper por-. tion of the ring 11 is adapted forengagement with a portion of the tone arm which is of less diameter than the extreme outlet end thereof. Thus when the rin 11 is coupled to the collar 10 it alsorcon nes the enarged outlet end of the tone arm 12.

A pin 12 is mounted in the tone airmiQ and normally rests upon. the upper edge- .f the coupling ring 11. This pin IQWI'IDS stop or limiting member to prevent the tone" arm from moving bodily downward within the collar 10. v

The chamber 15, formed between walls 5 and the side walls of the box 1, constitutes a housing or receptacle for the turn tablelfi which supports record disks 17. The tone arm 12 carries any improved sound box 18 with its stylus, '19 to enga'ge the disk 1'7, and

roduce sound in theordinary way.

side walls 20' of the 'box 1 extend abovethe horizontal plane of the turn table,} and turn buttons 21 are provided on the side .-walls which are ada ted to be moved inwardly and clamp a p ur'alit "of record disks -1-?onthe-turn table 16., his isdesirable carrying .the box from lace .to place,

as it provides room for sever records.

When the box it is necessary to first disconnect the tone'arm 12 and locate the same in the drawer 3, when the cover 2 can be closed .andthe box will occupy but small space operation the sound waves from the tone arm 12 are directed into the chamber 9,

and find an outlet through the perforations -7, hence the sound waves pass upwardl through plates 6 and horizontally throug the wall 5, the'c'over 2 acting as a sound I board ordeflector-to direct the sound waves ascribed my invention,
