Application filed September 11, 1323. Serial ITO/662,031.

My invention relates to phonographs or sound reproducing apparatus and, generally stated, its ob ect generally is to increase the volume andquality of the tone and at the same time secure faithful reproduction of.

the recorded sound.

More specifically the object of my invention is to reproduce or impart natural'tone to recorded or transmitted sounds and to amplify, modify, separate and balance the tones of different instruments and voices and also to eliminate all. objectionable and mechanical noises.

'By my invention it becomes possible to dispensewith the horn ordinarily employed and to cause the sounds to be reproduced wholly by sound boards and resonators.

To these ends, my invention consists essentia lly in delivering the sounds from the tone arm into a space or enclosure. one or more bounding walls of which consist of a freely vibrating sounding board, the enclosure into which the sound is so delivered being completed by 'other suitable sound confining boards some or all. of which may be freely vibrating sound boards free to vibrate at their'edges as hereinafter described. In some cases, said sound confining boards which complete the enclosure may have the function only of confining the sound and not be themselves the source of sound vibrations but, in such case, they must be so applied to completethe enclosure as not to interfere with the free vibration of the sound boardscwhich respond to the sound within the enclosure and serve directly or in conjunction. with other devices to reproduce the tones or vibrations.

My invention consists also in a phonograph cabinet or enclosure and in details of construction of sound amplifying devices and resonators and in the arrangement of the same, as hereinafter more particularly described and then specified in the claims. In the accompanying drawings. I have shown my invention as embodied in or carried out in connection with apparatus having features of construction and characteristic devices that are described and claimed in my prior Patent l To. 1,48'Z',299 dated March 18, 1924.

My invention is however useful in con-1 nection with reproducing apparatus of other forms as will be apparent from the subjoined description taken in connection with the accompanying drawings. in which Fig. 1 is avertical central section through the apparatus in its preferred form.

Fig. 2 is a perspective view ofthe bank of amplifying boards used in the space or e0 enclosure connected directly to the tonearin or outlet thereof through which the sounds reproduced by the stylus are delivered. Fig. 3 illustrates in perspective one of said boards with the preferred shape of end thereof where it bears against a sounding board or bridge therefor.

Fig. 4; is a perspectiveview of the top of I the apparatus with a part shown in section and other part broken away.

Fig. 5 is a perspective view of the reso-., nator forming the enclosing bottom of the stand or cabinet.

Fig. 6 is'a perspective view of a board or wall suitable for use in completing the enclosure, one side or wall of which consists of the freely vibrating sound board respons'ive to the sounds delivered from the tone arm into the enclosure. V

Fig. 7 is a perspective view of aportion of the bank or rack of sound boards form ing a sound vibrational carrier and amplifier between the freely vibrating sound board forming a wallof the enclosureinto which the sounds are directly delivered from thetone arm and a vertical resonator arranged within the reproducer cabinet.

These side walls 8. are engaged nrsound conducting relatlon-through racks orbanks of sound transmitting and amplifying boards 9 with cated-in Fig; 2, vibratively engaged and connected by. their surfaces withthe surfaces of the boards 8 by sound posts or dowels 11 which are glued directly secured in firm .engagementwith the various boards so as to' form. a; solid .medium font-ransinitting sound between them. The rack or bank of V vboards may be sustained within the enclosure which the sound boards 8 forms wall and extend downwardly fronithe out let 7 and preferably into proximity to a sound reflector 12 whieh'may be of concave form" as shown, tozreflect the sounds up- 'wa'rdly and outwardly, and the boards of jrthe sound amplifying-lack are of graduated or different lengths as indicated, for the spruceboard, or. mavbe made of other.

As

which rest up on shown, the centralboard 11 of the amplifying rack is used for this purpose, said central board being connected in sound vibrative relation, through sound posts, with the remaining members of the rack or bank at opposite sides thereof. Preferably, the end of the board 11 is cut into an arch, as indirated in Fig. 3, to form abridge, the abut- Y ments of the bridge being preferably liev eled orsharpened to'engagze the notches; 14'

in the resonator bridges lh'thereby holding the board 11? in positionand-insuring solid, vibrational COIIDBCtlOH thereo It will be seen that thesound posts of the rack or bank do not extend through all of the member boards of the amplifier but merely connect the same in pairs and that the posts of successive pairs are in staggered relation which, I find in'practice, is an advantageous relation for this member of the apparatus so far as concerns volume and capacity for-vibrating the different tones or rates of tones and for the effective transmission of thevibrations of one board to the others and to the sound boards '8 forming the walls the sound receivin enclosure already referred to. This same staggered successive pairs of sound boards is adopted also for the vibrational carriers and amphfiers 9 whirh are employed in a manner brations from the sides 8 ofthe amplifierv to the sides of the resonators 10.

with s the relation of sound posts ordowels between" Also. as will be seen, the edges of the sound hoards forthe banks 9 are cut away or tapered to. assist int-ho production of sound, effects therefrom; Thefsound posts connectingthe sides 8 with theraolrs Q are tension by cross rods 17 which .connect bearinn" clips or bars l8 bearing against the outindicated at 15 and the sound posts connesting the raclrs or banks 9 withthe sides side corners of the resonators 10, as shown inhig, l0 compression being applied by means ofthe thumb nuts 19, as'de'scribed. in my prior application. r

The resonator 1() at thcileft is sustained r in v rtical position by posts; as shown. on

gaging thetop ofja table or support 20 in the base and the bottom of the table 3, while the resonator 10 at the right is supported in a similar way in upright position, excepting mission of the vibrationsendwise from the amplifying rack within the space bounded by the wall 8,1 prefer to employ two resonators or sets of sounding boards 13 arranged in crossed relation as shown in Fig. 11, and to apply to each a bridge 14 in such way that it will be sustained at its opposite ends respectively by the members forming the pair of resonators 13. Each said resonator may consist of a pair of sounding boards connected by sound posts, as indicated, so that it will be open at its edge but its ends are closed by solid blocksof wood 22, as shown in Fig, 11, which receive sup porting bolts 23, the latter passing through openings in the diagonal bases 01' blocks 24: at the comers of the framing at the bottom of the cabinet or enclosure, as illustrated in Fig. 12.

The top of the cabinet is closed in by aresonator one board of which, forming the upper board of the resonator and indicated at 25, covers the entire area of the top. Said board 25 may have scroll or F-openings or holes F cut out in position shown in Fig. 4; to improve the acoustic effects or reproductions given out by said top resonator. The lower sound board of this resonator, indicated at 26, is approximately only one-half the size of the upper board 25, although I do not limit myself to this proportion of size. It is suitably secured at its edges in the side wall of the cover. A sound post is forced between these boards to keep them in tension and the lower board 26 is preferably formed with an opening 26 which, in conjunction with the scroll openings, permits the air ito circulatebetweenand around the boards and prevents sound reflections.-

As will be seen, the two boards form in effect a resonator with one end open. Opposite the open end, one or moresound boards 2'7 are disposed and suitably supported'in the sides of the cover. These boards are preferably arranged so that the plane of each board will form. an angle with the plane of the sound boards of the res-' onator. One ofthem extends partially into the space between said boards 25 and 26 and, for the best effects, the plane of each board 27 forms an angle .with that of the other. The edges of the boards preferably taper to a point or are reduced at their lower ends and do not. touch at any other.

point excepting that where they aresupported in the sides of the cover.' These boards respond to the vibrations set up in the top resonator and act to further amplify said sounds and improve the quality by responding to different rates of vibration,

said boardsbeing, 'as shown, ofdifierent is to utilize and amplify the musical sounds in the top ofthe machine and in amplifyingws-aid inuslcal sounds the ob ectionable .mcchanical sounds are practically masked 'or eliminated.

The bottom of the cabinet is closed by a resonator, the two boards of which are indicated at 28while 29 shows the sounduposts connecting them. erly supported firmly in the base and is preferably provided with the oval openings 32 cut out as illustrated inFigs. l and 5 and The object of the arrangement described Said resonator is pi'opwith the F or scroll openings 51, as indicated in Fig. 5, these openings beingfor the same purpose as those provided n the resonator fornnng the top of the cabinet. The sounding boards of the resonator 28 may be kept under tension by one or more sound posts interposed between the upper board 28 and the resonator 13 as shown in Figs; 1 and 11,

In practice, I utilize only the two side walls 8 fortransference of the vibrations to the vertically. disposed resonators, in.

which case the remaining two walls '8 may be constructed as indicated in F 1g. 6. Said walls 8 close the space between the two side walls 8 to complete the enclosure connected with the tone arm and each wall 8 may be provided with the dowels at its upper end and with a flange at its lower end for holding the same in place. Each wall is also provided withflanges or extensions 30,

81' extending at right angles from the plane thereof, the flange 30 lapping uponthe outer side of the sides 8 and thefiange 31 entering in the space between the side 8 and the outer member of the bank of boards forming the As will be seen, the flanges .pro-

The purpose of this construction is to forn' a good closure at the corners where the sides 8 and 8 meet without interfering with the free vibrations of the sides 8. What I claim as my invention 1s:-
