My present invention relates to. an improve toiiportable phonographs and has to do with the provision oflan improved form of sound deflectoioahorn. V

' Oneof the main advantages, of my device is that, owingto its structure, it is of a.com

dimensions of this type of phonograph, while permittingof full amplification ofthe sound in Volume and quality of tone.

A furtheradvantage is .the provision of means whe'reby thesound deflectorh may be.

adjusted to varying positions soas to direct and concentrate the sound as desired. V 7 These and other capabilities will be understood as the description proceedsahd it is obvious that modifications may be made'in the structure herein without departing from the spirit hereof, or the scopeof the appended Fig. 2'isa fragmentary plan view thereof 1 With the lcover :removedto better show the application of the, deflector.

haying ahinged cover 4, a turntable 5, a plat-.

j form 6, upon which is rotatably supported the Qturntable mom, not shown, and theusual' well knowniappurtenances, includ ng in the, present instance, a sound box 6 with itstapering amplifying tone tube or chamber 8.:

swivelled tone arm 7 leading to a tortuous,

The tone chamber 8 is preferably mounted upon the under side of a platform 6, so that in the usual style of structure the turntable the deflector shown, in adj ustand its attached parts may be readily removed I At the center of the disks 1 O 10.is provided a pair of pivots 13-13 upon which is plvotally mounted a semi-cylindrical deflector hood 14:, this beingprovided at its ends with alpair of end closure plates 1515, wherebysaid hood may be pivotally attached tothe end closing disks 1010 and adjustably regulated for tone direction, as indi cated in Fig. 5, wherein theflxed deflector 9 and the pivotal hood 14 are shown conforinably assembled for radialrelative adjustment. Between) the deflector and hood is lo- "cated a piece of felt 16, preferably afliXed to the deflector to prevent vibrationof the component metallic deflector hood. and v to pro- Vide also a'fr-ictional means to hold the hood in desired manually adjusted'position. This figure also discloses, in dotted contour, different positions of adjustment of the hood for tone deflection.- The hood may be flared at its upper edge as at-l7, as desired. V The. hood and deflector are so mounted as to encompass the elongated sound openmg 18 oftheinterior tapering tone chamber l .Bat its point ofintersection of the platform 'Y6',and the reafend ofthe, tone arm7, and thus to directthesound from the tone chamberupwardly and away fromfthe rear offthe phoiiograph, as illustrated .by the arrows,

Inoperation,,When the cover of the phonograph is closed, as in Fig. 1, the hood v17 when open "run, being relatively higher than the closed cover, is pushed backwardly'and downwater the lower edge 19 thereof, Figs.

The foregoing detailed description has been given for clearn-ess of understanding. Hence, no unnecessary limitations should be understood. Further, the appended claims should be construed as broadly as permissible in view of the prior art, since many and various changes may be made without departing from the scope of the invention as defined in the broader claims.

What I claim and desire to secure by Letters Patent is:

1. In a device of the class described, a portable casing, a platform in a portion thereof, said casing having a cover, sound reproducing means associated with said platform one one side thereof, a tone chamber associated with the platform on the opposite side and cooperating with said reproducing means to amplify sound therefrom, said platform being provided with an aperture communicating with said tone chamber, a tone deflector on said platform adjacent said aperture, and a deflector hood movably associated with said tone deflector, said cover cooperating with said deflector hood, when in opened position, to direct and concentrate sound issuing from said aperture.

2. In a device of the class described, a portable casing having a hinged cover, a platform in said casing adapted to support thereon sound reproducing means, said cover in closed position completely enclosing said means, means providing a sound amplifying chamber associated with the under side of said platform and connected to said sound tone deflector affixed to said platform and encompassing said aperture, a deflector hood pivotably mounted on said tone deflector, said hood having a flared portion, said platform having a second aperture therein to receive another portion of said hood when said hood is pivoted.

3. In a portable phonograph a platform, to support on the face thereof a sound reproducing mechanism, an amplifying chamber, connected to said mechanism and positioned under said platform, said chamber having a sound outlet through said platform, an adjustable cylindrical sound deflector, passing through a slot in said platform andextending over said outlet.

4. In a portable phonograph, a platform adapted to support on one face thereof sound reproducing mechanism, an amplifying chamber means on the other face of said platform, one end of said chamber being connected .to said mechanism, the other end opening into an aperture in said platform, a sound deflector surrounding said platform aperture, means associated with said deflector to retain the same in predetermined positions.

5. A phonograph comprising, a casing having a pivotable cover, a platform positioned at the top of said casing and adapted to support thereon sound reproducing mechanism,

' an amplifying tube in the space between said casing and platform, said tube having two open ends and being tapered from one end to the other, one of said ends being connected to said mechanism, the other end registering with an aperture in the platform, said platform having therein a second aperture between said first aperture and a casing wall, a pair of plates affixed to said platform, a semi-cylindrical tone deflector affixed to said plates and platform and encompassing said first aperture, a pivot plate movably mounted on each fixed plate, a semi-cylindrical deflector hood affixed at the ends thereof to said pivot plates for movement therewith, one side of said hood being flared, the opposite side passing through a slot in said platform when said hood is moved into non-deflecting position, apiece of felt positioned between said hood and deflector to retain said hood in a predetermined position, said cover, when in open position, cooperating with said'hood, when in sound deflecting position, to direct and concentrate sound issuing from said first aperture.

6. A phonograph, including a platform, to support a sound reproducing mechanism thereon, a sound amplifying chamber, positioned under said platform, connected to said mechanism and opening into an aperture in said platform, an adjustable cylindrical sound deflector, having thereon a flared por tion, extending over said aperture and pass ing through a slot in said platform, and means for adjustably supporting said deflector in position.

7 A sound deflector, to be used on a portable phonograph, having thereon a platform and a sound. outlet through said platform, said deflector comprising a semi-cylindrical hood, passing through a slot in said platform, adjacent said outlet, and means to pivotally position said hood at said outlet, to extend over said outlet.

8. A sound deflector hood as in claim 7, said means including a stationary cylindrical sound deflector, a portion thereof being con centrical with said hood, said hood being manually adjustable in position with relation to said stationary deflector, and frictional means on said stationary deflector, for keeping said hood in position thereon;

9. A phonograph comprising, a casing having a cover pivoted'at the rear wall of said casing, a platform affixed to said casing di viding said casing into an upper and a lower compartment, when said cover is in closed position, sound reproducing mechanism on said ment when said cover is close platform and disposed in the dipper comdparta soun amplifying chamber in the lower compartment,

7 said chamber being connected to said mechanism, and opening into an aperture in said platform adjacent said rear wall, and a curvilinear sound deflector adjustably passing through a slot in said platform and extend-- ing over said aperture.
