The usual or any suitable horizontal turn-2 table 35 is arranged slightly above the, top wall 2 of the casing and is mounted upon the upper end of a vertical spindle 3,6, which extends rotatably through the top wall '2,

and is sup .orted in suitable bearings, ar ranged with from the op al Arranged a o e th turn ab e 3.5 is the usual sound box; or sound reprodueer e5, which is suitably connected to the free end f a ell w on arm 46 wi h w ich it. om-

Of th e ing i a o Pre erably:

horizontally er-tie in the cas ng and depending munieates, the sound box being'arranged tobiiooperate'with a record 38 upon the tux-n1 ta e.

The outer end of the tone arm 46 curves downwardly and engages rotatively on the upper free end of a downwardly flaring hole 10w metal bracket 47 with which it corn; municates, The hollow flaring bracket 47 terminates at its lower end in an inwardly flaring sound amplifier socket integral therewith and comprising two inwardly di- ,vergijng oppositely disposed flat vertical walls or flanges 50 and an inwardly and downwardly extending flat longitudinally v horizontal wall or flange 51 terminally con- -;-;nected to the lower ends of the vertical "'iianges 50 and integral therewith. This the casing froni-the side tively'f'of the downwardly inc ined soun 'ng connect t socket fits snugly in a corresponding recess 52 in the upperportion of theback wall 5 of the casing and pro ects inwardly into the space inclosed by the casing.

Integral with the rear portion of the sound amplifier socket 50, 51 and resting against the outer surface of the back wall 5 are oppositely disposed flat vertical flanges 53 and a flat longitudinally horizontal flange 54 terminally connected to the lower ends of these vertical flanges. Screws 55 extendin lie hollow bracket 47 securely and substantiall rigidly to the casing.

For am ifying and deflecting boards may be arranged to project within the -fcasing from the amplifier socket 50, 51;

or otherwise tothe upper s rface of the,-

longitudinal horizontal flange 51 of the socket. Vertical sounding boards 62;and may be arranged to extend u wa'rdly within es 61 res ecboard 60. These latter sounding boards 62 and 63 diverge forwardly from opposite sides respectively of the socket 50, 51 and their upper edges 64 are preferably parallel to, but spaced slightly below, the inner horizontal surface of the top wall of thecaiing. The lower edges of the vertical sounding boards 62 and 63 are securely connectedjy glue or otherwise to the diverging side edges 61 respectively of the downwar ly inclined sounding board 60, and the rear ends of the vertical sounding boards are secured by screws 65 or otherwise to the inner surfaces respectively of the vertical flanges 50 of the amplifier socket. The upper edges 64 of each vertical sounding board 62 and 63 'may be reinforced by a slender wooden strip 66 flush therewith and secured thereto by glue or otherwise.

The usual or any suitable actuating mechanism 70 for the turntable spindle 36' is arranged within the casing, preferably depending from the top wall 2 thereof andmto the space 71 substantially inclosed by the top wall 2, and the thin diverging sou nding boards 60,62 and 63.

The rigid, vertical bridge-or sound post 75 of wood or other suitable material may I be arranged between the central portion of the downwardly inclined sounding board 60 through these flanges 53' and 54 the sound waves m t e casing 1, one or more sounding and the central portion of the-horizontalsounding board 14 betweenthe apertures 16f of the board, to transmit the. sound vibrations between these two boards, the ends of the post being in contact with the two boards respectively. The sound post may be omit- .passage of sound waves betwe'enthespace surrounded by these soundingf boards and out ends 76 in a vertical plane jthe space between the outer sides of these" boards and the outer wal1sof.thecasing.{

The three sounding boards 60,"?62ihlld 63 are thus entirely supported by theamplrfie'r' socket 50, 51 and by the sound post 75"and.

the latter is proportioned so that'itsupperl end receives only a slight pressure, lfapy,

the downwardly inclined soundin board 60. These three sounding boar s =f orm a three-sided device which coiiperates with the top wall of the casing from-the- .major portion or delivery end of a sound conduit or am lifier through which sounds are transmitt from'the hollow bracket 47.

vention, sound waves produced by the sound In the operation of this form of the in-- ..'box are transmitted through the tone arm A46 and hollow bracket 47 into the space 71' ;containin the actuating mechanism 70 and substantia y inclosed by the top wall 2 and the diverging sounding boards 60, 62 and 63. The sound waves in this space cause the diverging sounding boards to vibrate and the vlbration is transmitted .to the bottom horizontal sounding board through the sound post 75. Thesounds produced are delivered from the machine mainly through the screen 26 when the doors 25 are open, but some sound is transmitted through the horizontal sounding board 14 at the bottom of the casing and is delivered from the machine through the spaces between the standards 20 of the cas1n In view of the fact t at the theories of the operation, and the advantages of this construction may not be fully known or 'appreciated at this time, the right is reserved to supplement this disclosure by further state-' ments in the specification in regard to; the. mode of operation of the device, and in regard to-the advantages of its various features. v w
