UNITED STATES PATENT HERMANN SGERODER, Q1 NEW YORK, N, Y.

1'0 all whom it may concern:

Be it known that I, HERMANN Sonnonnn, a citizen of the United States, residing at New York in the county of New York and State of new and useful Improvements in'Resonance- -Chambers for Sound-Reproducing Appation.

This invention relatesto improvements in sound reproduction apparatus and more articularl to an improved resonance ox,

ratus, of which the following is a specificasound. 0 amber and sound outlet for all types" provide a resonance box, sound chamber or basin so constructed as to ada t it to contain a volume of water or other 'iquid 1n order to produce the advantageous results above mentioned.

The inventionalso has as its object to provide a resonance chamber and sound outlet which will add greatly to the appearance of the instrument 1n connection with which it is employed. l

In the accompanying drawings:

Figure 1 is a perspective view of a cabinet phonograph, equipped with the resonance chamber and sound outlet embodying the invention Fig. 2 is a horizontal sectional view throu h the forward portion of the cabinet andi ustrating the forward portion of the said chamber inplan;

ment 3 opens through the front fof the cabinet. V

The resonance chamber, embodyin the present invention is clearly shownin iig', 4 of the drawings. and the said chamber. is indicated in general bythe numeral 5 and comprises a flared body 6 havingside walls 7, a

co the cabinet 1 is open at the upper top wall 8, and a bottom wall 9. The chamher 5 is of general recta'n lar form in cross section but its side we s 7 converge in a rearward direction and its top wall 8 is inclined' downwardly and rearwardly so that the chamber is of greater dimensions at its delivery end 10 than at its inner end. The said Walls of the chamber at the inner end thereof merge and form an u neck 11 tapered in the direction of its upper end and connected in any suitable manner at its said end with the lower end of the tone arm 2. The delivery resonance chamber is disposed a proxiinately'fiush with the open side 4 of t ecabinet 1 as clearly shown m Fig. lot the draw ing's, or it may rotrude in an ornamental.

manner upwar y or downwardly away from the said front and while the said end of the resonance box is illustrated in the drawings as left entirely open, it will be of the ordinarymeans partly closing the same.

As previously stated, the resonance box pwardly curved end 10 of the of the present invention is so constructed that it may contain a volumeof water or other li uid which will serve as a medium for mo ulating the reproduced tones and uality. In-order that the resonance cham er or sound outlet may beso adapted, its bottom wall 9-is disposed horizontally and the said wall is extended forwardly beyond the delivery end 10 of the box to form the bottom 12 of a basin indicated in general by the numeral 13. Likewise the bottom wall 12 is extended laterally as at 14 and at its lateral portions'is likewise preferabl extended rearwardl as at 15 so that the ottom of the basin will not only extend in front of the cabinet 1 but also partly at the sides 4 shown in Fig.

thereof. The purpose of this construction will presently be made clear. The numeral 16 indicates the upright wall of the basin which wall has a front portion 17,- side portions 18 which extend at the outer edges of the respective portions 16 of the bottom ofthe basin, and other portions 19 which extend opposite the portions 18 and around the forward corners of the open front of the compartment 3 as at 20 and are joined to the side walls 7 of the resonance chamber. Thus the basin extends not only within the interior of the compartment 3 but also across the front of the said compartment and consequently across the front of the cabinet, and also partly at the sides of the cabinet.

The resonance chamber will preferably be made of glass although any other material or combination of'materials may be employed for this purpose and it will be'understood that the exposed portions of the .said chamber may be suitably ornamented so as to add to the attractive appearance of the cabinet of the instrument as a whole. In the lateral portions of the basin, and if desired even in the front portion thereof, flow ers may be arranged so as to further add to the appearance of the instrument, the basin beingfilled to any desired level with water or any other liquid as best shown in Figs. 1 and 3 of the drawings.

In order that the liquid may be drawn of? whenever desired, a drain pipe 20 is fitted through the rear end of the basin as best 3 of the drawings and leads through the rear wall of the cabinet 1 and is provided with any suitable type of fancet21.'

As before stated, cut flowers or aquaticplants may be arranged within the lateralor even the front portion of the basin, and also ifi desired. various aquarium ornaments ma be arranged within the basin..-

ile as stated it is preferable that the I neeaeoa as reproduced are modulated in the same manner as are other musical sounds when heard across a body of water.

Having thus described the invention, what is claimed as new is:

1. A resonance chamber for sound reproducing apparatus having in its lower por- By reason tion a bottom, and a wall completely surrounding the bottom and providing a basin adapted to contain a volume of liquid.

2. A resonance chamber for sound reproducing apparatus having a liquid containin basin forming its lower portion, the said basin extendin to a point in advance of the delivery end 0 the chamber.

3. A resonance chamber for sound reproducing apparatus having a liquid containing basin forming its lower portion, the said basin extending to a point in advance of the delivery end of'the chamber and being also extended laterally. 4. A resonance chamber for sound reproducing apparatus having bottom, side and top walls, the bottom wall being extended beyond the delivery end of the chamber, and an upright wall surrounding the extended portion of the bottom wall-whereby to'provide a liquid containing basin.

5. A resonance chamber for sound reproducing apparatus, having a lower portion constructed to contain a volume of liquid, and valved means whereby the liquid may be drained from the said chamber.

In testimony whereof I afiix my signature.

HERMANN- SCHRODER.
